Visceral adipose tissue predicts severity and prognosis of acute pancreatitis in obese patients

Acute pancreatitis is a common systemic inflammatory disease, manifested by a spectrum of severity, ranging from mild in the majority of patients to severe acute pancreatitis. Patients with severe acute pancreatitis suffer from severe local and systemic complications and organ failure, leading to a poor prognosis. The early recognition of the severe condition is important to improve prognosis. Obesity has risen in tandem with an increase in the severity of acute pancreatitis in recent years. Studies have revealed that adipose tissue, particularly visceral adipose tissue is associated with the prognosis of acute pancreatitis. This review discussed the role of visceral adipose tissue in obese patients with acute pancreatitis and explored the possible mechanism involved.

Evaluation of retinal and choroidal thickness changes in overweight and obese adults without ocular symptoms by swept-source optical coherence tomography

AIM:To evaluate the relationship of overweight and obesity with retinal and choroidal thickness in adults without ocular symptoms by swept-source optical coherence tomography(SS-OCT).METHODS:According to the body mass index(BMI)results,the adults enrolled in the cross-sectional study were divided into the normal group(18.50≤BMI<25.00 kg/m^(2)),the overweight group(25.00≤BMI<30.00 kg/m^(2)),and the obesity group(BMI≥30.00 kg/m^(2)).The one-way ANOVA and the Chi-square test were used for comparisons.Pearson’s correlation analysis was used to evaluate the relationships between the measured variables.RESULTS:This research covered the left eyes of 3 groups of 434 age-and sex-matched subjects each:normal,overweight,and obesity.The mean BMI was 22.20±1.67,26.82±1.38,and 32.21±2.35 kg/m^(2) in normal,overweight and obesity groups,respectively.The choroid was significantly thinner in both the overweight and obesity groups compared to the normal group(P<0.05 for all),while the retinal thickness of the three groups did not differ significantly.Pearson’s correlation analysis showed that BMI was significantly negatively correlated with choroidal thickness,but no significant correlation was observed between BMI and retinal thickness.CONCLUSION:Choroidal thickness is decreased in people with overweight or obesity.Research on changes in choroidal thickness contributes to the understanding of the mechanisms of certain ocular disorders in overweight and obese adults.

Piperine regulates the circadian rhythms of hepatic clock gene expressions and gut microbiota in high-fat diet-induced obese rats

The interplay between the host circadian clock and microbiota has significant influences on host metabolism processes,and circadian desynchrony triggered by high-fat diet(HFD)is closely related to metabolic disorders.In this study,the modulatory effects of piperine(PIP)on lipid metabolism homeostasis,gut microbiota community and circadian rhythm of hepatic clock gene expressions in obese rats were investigated.The Sprague-Dawley(SD)rats were fed with normal diet(ND),HFD and HFD supplemented with PIP,respectively.After 9 weeks,rats were sacrificed with tissue and fecal samples collected for circadian analysis.Results showed that chronic PIP administration ameliorated the obesity-induced alterations in lipid metabolism and dysregulation of hepatic clock gene expressions in obese rats.The gut microbial communities studied through 16S rRNA sequencing showed that PIP ameliorated the imbalanced nicrobiota and recovered the circadian rhythm of Lactobacillaceae,Desulfovibrionaceae,Paraprevotellaceae,and Lachnospiraceae.The fecal metabolic profiles indicated that 3-dehydroshikimate,cytidine and lithocholyltaurine were altered,which were involved in the amino acid and fatty acid metabolism process.These findings could provide theoretical basis for PIP to work as functional food to alleviate the lipid metabolism disorder,circadian rhythm misalignment,and gut microbiota dysbiosis with wide applications in the food and pharmaceutic industries.

Effects of excessive body fat on colostrum lipid patterns: overweight/obese vs. normal weight mothers

Prenatal overweight/obesity(OW/OB)can alter colostrum lipid patterns,thereby affecting the lipid metabolism and even the cognitive and healthy development of infants.However,studies on changes in colostrum lipids in the context of OW/OB are limited,particularly for glycerides and polar lipids.Therefore,this study investigated the infl uence of maternal prenatal weight on colostrum in lipid subclasses and molecular species.The concentration of triacylglycerols(TAGs)in the colostrum of the OW/OB group(35894.43 mg/L)was higher than that of the normal weight(NW)group(26639.20 mg/L),suggesting that colostrum from OW/OB mothers could provide more energy to their infants.Further analysis of the fatty acid composition of TAGs revealed that elevated maternal body weight enhanced the concentration of TAGs containing saturated or n-6 fatty acids and shortened the carbon number of TAGs.Docosahexaenoic acid(DHA)/arachidonic acid(AA)/choline-containing lipids,such as DHA-containing TAGs,AA/DHA-containing phosphatidylethanolamine,and choline-containing phospholipids,were present in higher levels in the colostrum of OW/OB mothers than NW mothers.However,the concentrations of palmitic acid-containing TAGs,linoleic acid-containing TAGs,dihomo-γ-linolenic acid-containing TAGs,and polar lipids and the ratio of TAGs containing n-6 fatty acid/n-3 fatty acid were signifi cantly higher in the colostrum of OW/OB mothers than in that of NW mothers.The fatty acid composition and sphingoid bases of sphingolipids were also altered due to elevated body weight.In conclusion,OW/OB affects colostrum lipids with respect to composition,concentration,and percentage.Although the colostrum of healthy OW/OB mothers can provide suffi cient DHA/AA/choline-containing lipids to their infants,normalization of body weight and fat reserves should be considered as a strategy for highquality human milk lipids.

Diet restriction and exercise alleviate cognitive reduction of high fat diet (HFD)-induced obese mice by rescuing inflammation-mediated compromised insulin signaling pathway through activating AMPK/SIRT1 signal pathway and suppressing TLR4 signal pathway

Obesity,caused by excessive energy,leads to body weight gain and various diseases,including cognitive impairment.Current studies suggest that diet restriction such as optimal fasting and regular exercise are crucial for improving cognitive capacity.However,further exploration is needed to understand the specific mechanisms of high fat diet(HFD)-induced cognitive decline in obesity.In the present study,4-month-old mice were subjected to HFD feeding for 18 weeks,followed by aerobic exercise and high-intensity intermittent exercise,regular diet feeding,and intermittent fasting for 8 weeks,and then used to evaluate cognitive capacity,inflammation,compromised insulin signaling pathway,and apoptosis in hippocampal tissue,as well as AMPK/SIRT1 and TLR4 signal pathways.Obese mice revealed impaired cognitive capacity as compared with mice fed with regular diets.In contrast,aerobic exercise,high-intensity intermittent exercise,regular diet,and intermittent fasting could inhibit apoptosis caused by inflammation-mediated compromised insulin signaling pathway in hippocampal tissues through activating the AMPK/SIRT1 signal pathway and suppressing the TLR4 signal pathway,thereby rescuing the cognitive impairment of obese mice.Therefore,diet restriction and exercise interventions may play a positive role in reverting obesity-induced cognitive impairment.

Interaction between adolescent sleep rhythms and gender in an obese population

BACKGROUND The obesity rate of adolescents is gradually increasing,which seriously affects their mental health,and sleep plays an important role in adolescent obesity.AIM To investigate the relationship between sleep rhythm and obesity among adolescents and further explores the interactive effect of sleep rhythm and gender on adolescent obesity,providing a theoretical basis for developing interventions for adolescent obesity.METHODS Research data source Tianjin Mental Health Promotion Program for Students.From April to June 2022,this study selected 14201 students from 13 middle schools in a certain district of Tianjin as the research subject using the convenient cluster sampling method.Among these students,13374 accepted and completed the survey,with an effective rate of 94.2%.The demographic data and basic information of adolescents,such as height and weight,were collected through a general situation questionnaire.The sleep rhythm of adolescents was evaluated using the reduced version of the morningness-eveningness questionnaire.RESULTS A total of 13374 participants(6629 females,accounting for 49.56%;the average age is 15.21±1.433 years)were analyzed.Among them,the survey showed that 2942 adolescent were obesity,accounting for 22%and 2104 adolescent were overweight,accounting for 15.7%.Among them,1692 male adolescents are obese,with an obesity rate of 25.1%,higher than 18.9%of female adolescents.There is a statistically significant difference between the three groups(χ2=231.522,P<0.000).The obesity group has the smallest age(14.94±1.442 years),and there is a statistical difference in age among the three groups(F=69.996,P<0.000).Obesity rates are higher among individuals who are not-only-child,have residential experience within six months,have family economic poverty,and have evening-type sleep(P<0.05).Logistic regression analysis shows a correlation between sleep rhythm and adolescent obesity.Evening-type sleep rhythm can increase the risk of obesity in male adolescents[1.250(1.067-1.468)],but the effect on female obesity is not remarkable.Further logistic regression analysis in the overall population demonstrates that the interaction between evening-type sleep rhythm and the male gender poses a risk of adolescent obesity[1.122(1.043-1.208)].CONCLUSION Among adolescents,the incidence of obesity in males is higher than in females.Evening-type sleep rhythm plays an important role in male obesity but has no significant effect on female obesity.Progressive analysis suggests an interactive effect of sleep rhythm and gender on adolescent obesity,and the combination of evening-type sleep and the male gender promotes the development of adolescent obesity.In formulating precautions against adolescent obesity,obesity in male adolescents with evening-type sleep should be a critical concern.

Effects of exercise training on glucose metabolism indicators and inflammatory markers in obese children and adolescents:A metaanalysis

BACKGROUND Obesity in children and adolescents is a serious problem,and the efficacy of exercise therapy for these patients is controversial.AIM To assess the efficacy of exercise training on overweight and obese children based on glucose metabolism indicators and inflammatory markers.METHODS The PubMed,Web of Science,and Embase databases were searched for randomized controlled trials related to exercise training and obese children until October 2023.The meta-analysis was conducted using RevMan 5.3 software to evaluate the efficacy of exercise therapy on glucose metabolism indicators and inflammatory markers in obese children.RESULTS In total,1010 patients from 28 studies were included.Exercise therapy reduced the levels of fasting blood glucose(FBG)[standardized mean difference(SMD):-0.78;95%confidence interval(CI):-1.24 to-0.32,P=0.0008],fasting insulin(FINS)(SMD:-1.55;95%CI:-2.12 to-0.98,P<0.00001),homeostatic model assessment for insulin resistance(HOMA-IR)(SMD:-1.58;95%CI:-2.20 to-0.97,P<0.00001),interleukin-6(IL-6)(SMD:-1.31;95%CI:-2.07 to-0.55,P=0.0007),C-reactive protein(CRP)(SMD:-0.64;95%CI:-1.21 to-0.08,P=0.03),and leptin(SMD:-3.43;95%CI:-5.82 to-1.05,P=0.005)in overweight and obese children.Exercise training increased adiponectin levels(SMD:1.24;95%CI:0.30 to 2.18,P=0.01)but did not improve tumor necrosis factor-alpha(TNF-α)levels(SMD:-0.80;95%CI:-1.77 to 0.18,P=0.11).CONCLUSION In summary,exercise therapy improves glucose metabolism by reducing levels of FBG,FINS,HOMA-IR,as well as improves inflammatory status by reducing levels of IL-6,CRP,leptin,and increasing levels of adiponectin in overweight and obese children.There was no statistically significant effect between exercise training and levels of TNF-α.Additional long-term trials should be conducted to explore this therapeutic perspective and confirm these results.

Global research trends and hotspots in overweight/obese comorbid with depression among children and adolescents: A bibliometric analysis

BACKGROUND Overweight/obesity combined with depression among children and adolescents(ODCA)is a global concern.The bidirectional relationship between depression and overweight/obesity often leads to their comorbidity.Childhood and adolescence represent critical periods for physical and psychological development,during which the comorbidity of overweight/obesity and depression may increase the risk of adverse health outcomes.AIM To evaluate the relationship between ODCA,we conduct a bibliometric analysis to aid in formulating prevention and treatment strategies.METHODS From 2004 to 2023,articles related to ODCA were selected using the Science Citation Index Expanded from the Web of Science Core Collection.Bibliometric analysis of relevant publications,including countries/regions,institutions,authors,journals,references,and keywords,was conducted using the online bibliometric analysis platforms,CiteSpace,VOSviewer,and bibliometrix.RESULTS Between 2004 and 2023,a total of 1573 articles were published on ODCA.The United States has made leading contributions in this field,with Harvard University emerging as the leading contributor in terms of research output,and Tanofsky being the most prolific author.The J Adolescent Health has shown significant activity in this domain.Based on the results of the keyword and reference analyses,inequality,adverse childhood experiences,and comorbidities have become hot topics in ODCA.Moreover,the impact of balancedrelated behavior and exploration of the biological mechanisms,including the potential role of key adipocytokines and lipokines,as well as inflammation in ODCA,have emerged as frontier topics.CONCLUSION The trend of a significant increase in ODCA publications is expected to continue.The research findings will contribute to elucidating the pathogenic mechanisms of ODCA and its prevention and treatment.

Comparative observation of the effectiveness and safety of remimazolam besylate versus dexmedetomidine in gastrointestinal surgery in obese patients

BACKGROUND Surgery for obese patients carries a higher risk of anesthesia complications compared with surgery for nonobese patients.Thus,a safe and effective anesthesia strategy is necessary to improve the medical experience of such patients and ensure their safety.AIM To compared the effectiveness and safety of remimazolam besylate versus dexmedetomidine(DEX)in gastrointestinal surgery in obese patients.METHODS The study cohort included 60 obese patients undergoing gastrointestinal surgery between July 2021 and April 2023,comprising 30 patients who received DEX intervention(control group)and 30 patients who received remimazolam besylate intervention(research group).Heart rate(HR),respiratory rate(RR),mean arterial pressure(MAP),blood oxygen saturation(SpO_(2)),safety(nausea and vomiting,bradycardia,hypotension,and apnea),anesthesia and examination indices[induction time,anesthesia recovery time,and postanesthesia care unit(PACU)discharge time],sedation effect(Ramsay Sedation Scale),and postoperative pain visual analog scale were comparatively analyzed before anesthesia(T0),during anesthesia(T1),and after anesthesia(T2).RESULTS At T1,the research group showed significantly smaller changes in HR,RR,MAP,and SpO_(2) than the control group,with a significantly lower adverse reaction rate and shorter induction,anesthesia recovery,and PACU discharge times.Additionally,the intra-and postoperative Ramsay Sedation Scale scores were statistically higher in the research group than in the control group.CONCLUSION Remimazolam besylate was significantly more effective than DEX in gastrointestinal surgery in obese patients and had a higher safety profile and value in clinical promotion.

MiRNA-200a and miRNA-200b expression,and vitamin-D level:Prognostic significance in obese non-diabetic and obese type 2 diabetes mellitus individuals

BACKGROUND Obesity and type 2 diabetes mellitus(T2DM)are frequent co-occurring disorders that affect regular metabolic functions.Obesity has also been linked to an inc-reased risk of developing diabetes.Obesity and diabetes are on the rise,increa-sing healthcare costs and raising mortality rates.Research has revealed that the expression profile of microRNAs(miRNAs)changes as diabetes progresses.Fur-thermore,vitamin D may have an anti-obesity effect and inverse association with body weight and body mass index(BMI).Low vitamin D levels do not solely cause obesity,which could be a factor in the etiology of T2DM.METHODS This study included 210 participants,of which,82 were obese(BMI>30 kg/m2)without T2DM,28 were obese with T2DM,and 100 were healthy controls.BMI was evaluated and both fasting and postprandial blood glucose were used to confirm T2DM.Exosomal miRNA-200a and miRNA-200b expression were analyzed using real-time PCR using Taqman probes,and vitamin-D levels were evaluated using an electrochemiluminescence-based immunoassay technique.All data analyses were performed using SPSS 20.0 and GraphPad Prism 5 software.RESULTS Overall,a 2.20-and 4.40-fold increase in miRNA-200a and miRNA-200b expression was observed among participants compared to healthy controls.MiRNA-200a and miRNA-200b expression among obese participants increased 2.40-fold and 3.93-fold,respectively,while in obese T2DM participants these values were 2.67-fold,and 5.78-fold,respectively,and these differences were found to be statistically significant(P=0.02)(P<0.0001).Obese participants showed a vitamin D level of 34.27 ng/mL,while in obese-T2DM participants vitamin D level was 22.21 ng/mL(P<0.0001).Vitamin D was negatively correlated with miRNA-200a(r=-0.22,P=0.01)and miRNA-200b(r=-0.19,P=0.04).MiRNA-200a sensitivity was 75%,and specificity was 57%,with a cutoff value of 2.07-fold.MiRNA-200b sensitivity was 75%,and specificity was 71%with a cutoff value of 4.12-fold,suggesting that miRNA-200a and miRNA-200b with an increased expression of 2.07-and 4.12-fold could be predictive indicators for the risk of diabetes in obese participants.CONCLUSION MiRNA-200a and miRNA-200b were higher in diabetic obese participants vs non-diabetic obese participants,and insufficient vitamin D levels in obese T2DM participants may be involved in poor clinical outcome.

Ovarian Reserve in a Population of Obese Infertile Patients in Kinshasa

Background: The ovarian reserve, which is an important marker in the management of couple infertility, undergoes depletion over time. This depletion could accelerate in the presence of certain circumstances, such as obesity. The contradictory results of studies on the impact of obesity on the ovarian reserve throughout the world accelerated ovarian ageing in infertile women from Kinshasa, as well as the high rate of obese women in this population, seemed necessary to undertake this study to find out if this obesity impacted the ovarian reserve of Kinshasa women. The objective of this study was to identify the profile of markers of ovarian reserve in obese infertile patients according to certain characteristics. Method: A case-control study with retrospective data collection on 439 obese infertile patients (cases) and 439 normal-weight infertile patients (controls) who had consulted for the desire to conceive at the University Hospital of Kinshasa and the Edith Medical Center between January 2016 and December 2021. Results: The average age of the patients was 33.6 years ± 4.3 years, with 47.8% of patients aged at least 35 years. Menarche and menstrual duration were correlated with AMH in linear regression (p = 0.043 and 0.021, respectively). Late menarche and irregular cycle were risk factors for ovarian ageing [OR: 4.6;95% CI: (1.052 - 20.636);p = 0.043 and OR: 4.8;95% CI: (1.633 - 14.566);p = 0.005] while PCO was a protective factor for ovarian ageing [OR: 0.109;95% CI: (0.182 - 0.652);p = 0.015]. Conclusion: Within the limits of our study, we found that the more obese the patients were, the faster the ovaries aged.

Epidemiological, Clinical and Paraclinical Profile of Osteoarthritis of the Lower Limbs in Obese Patients at the Cocody University Teaching Hospital

Objective: To describe the epidemiological, clinical and paraclinical characteristics of osteoarthritis of the lower limbs in obese patients at the Cocody University Teaching Hospital. Methodology: This was an analytical cross-sectional study carried out in the rheumatology department of the Cocody UTH in Abidjan (Ivory Coast) from March 1 to April 30 2023. Patients who came for rheumatology consultation presenting with mechanical arthralgia of the lower limbs, who were obese, had radiographic images were included. All patients without radiographic images were excluded. Obesity was defined as a body mass index (BMI) greater than or equal to 30 kg/m. The Chi2 test was used to compare proportions and determine the existence of associations between osteoarthristis and obesity, obesity severity and radiographic stage of osteoarthritis as well as the functional impact. A p-value below a predefined threshold (p = 0,05) indicates a significant relationship between the variables. Result: Out of 185 patients received for osteoarthritis of the lower limbs during the study period, 136 were obese (74%). There were 115 women (84.6%) with an average age of 56.03 with a standard deviation of 12.72 years (extremes: 22 and 84 years). The main socio-professional category was the informal sector (30%). The majority of patients had a low socio-economic level (80.2%) and lived in urban areas (92.6%). The most common past medical history was hypertension (33.08%) followed by peptic ulcer disease (16.91%). Patients had a body mass index class 1 (81.6%), class 2 (15.40%) and class 3 (2.90%). The average duration of symptom progression until diagnosis was 11 months. Genu varum was the main static disorder (56.10%) and the knee joint was the dominant topography (90.4%) with a bilateral localization (80%). The average Lequesne index was greater than 8 (59.5%). The Kellgren and Lawrence radiographic stages were stage 1 (9.20%), stage 2 (46.90%), stage 3 (29.20%) and stage 4 (6.90%). The Obesity severity was significantly associated with osteoarthritis of the knee (p = 0.042). There was no statistically significant association between obesity severity and radiographic stage of osteoarthritis (p = 0.163) or functional impact (p = 0.180). Conclusion: Osteoarthritis of the lower limbs affected obese women and was dominated by stage 2 osteoarthritis of the knee (Kellgren and Lawrence). There is an association between the severity of obesity and osteoarthritis of the knee.

Gunsight suture with subcutaneous vacuum drainage during enterostomy decreased the surgical site infection rate in obese rectal cancer patients:A retrospective study

Background:Surgical site infection(SSI)is the most common complication after stoma closure and is particularly common in obese patients.To reduce the incidence of SSI,various skin closure techniques have been proposed;however,the best technique is still under debate.The purpose of this study was to explore the effectiveness of subcutaneous vacuum drains(SVDs)after two surgical suture techniques following stoma reversal in obese patients. Methods:Data from 190 obese patients with rectal cancer who underwent stoma reversal for enterostomy between February 2012 and April 2023 at Jinxiang Hospital Affiliated to Jining Medical University were retrospectively analyzed.These patients were divided into two groups:gunsight suture(GS)with SVD and primary linear suture(PLS)with SVD.The GS group and PLS group included 90 and 100 patients,respectively.The clinical characteristics and short-term outcomes were compared between the two groups.Postoperative pain scores were analyzed using a generalized estimation equation. Results:Surgery was successfully performed in both groups.The rate of SSI in the GS group was significantly lower than that in the PLS group(2.2%vs 9.0%,P=0.046).Patients in the GS group had a significantly shorter wound healing time than did patients in the PLS group,as well as a significantly shorter postoperative fasting time(P<0.05).No significant differences were found between the groups in terms of the postoperative hospital stay,operative time,and estimated blood loss(P>0.05).The results of the generalized estimation equation analysis showed that the GS group had significantly lower pain scores at 12,24,48,and 72 h after surgery than the PLS group(P<0.05).Moreover,the GS group showed significantly better alleviation of wound pain between 12 and 72 h after surgery(P<0.05). Conclusions:The GS technique with SVD may be recommended for wound closure of a nonfunctioning stoma in obese patients.

Laryngeal mask airway bougie ultrasonography guided intubation in a morbidly obese patient with diffi cult airway

Airway management of morbidly obese patients is challenging due to inherent anatomical and physiological variations.[1]The frequent association of compromised hemodynamics,hypoxemia,or acidosis in an emergency department(ED)setting adds to the difficulty of the procedure.Rapid airway management position(RAMP),awake fiber-optic guided intubation,use of intubating laryngeal mask airway(ILMA),and video-laryngoscope are a few techniques that have been described to tackle difficult airways in these patients.[2]Studies have shown that the availability of fi ber-optic scopes(3%–60%),videolaryngoscopes(39%–88%),and laryngeal mask airways(LMA)(65%–83%)varies in different ED settings.[3,4]Furthermore,a lack of adequate training and the need for time-bound resuscitation make implementation of the above techniques challenging.

Edible mushrooms as a potent therapeutics of subclinical thyroid dysfunction among adults,especially in obese individuals:a prospective cohort study

Background:Mushrooms are a good source of many nutrients which are potentially beneficial for chronic diseases.We speculated that due to its abundant nutrients edible mushrooms might have a beneficial effect on the prevention of subclinical thyroid dysfunction(SCTD).Therefore,we designed a large-scale cohort study to examine whether mushrooms consumption is a protective factor for SCTD in adults.Methods:This prospective cohort study investigated 6631 participants(mean age:(45.0±10.2)years;55.1%men).Edible mushrooms consumption was measured at baseline using a validated food frequency questionnaire.SCTD was defined as abnormal serum thyroid-stimulating hormone levels and normal free thyroxine.Cox proportional hazards regression models were used to examine the association of edible mushrooms consumption with incident SCTD.Results:During follow-up period,a total of 262 new cases of SCTD were identified,the incidence rate of subclinical hypothyroidism was 8.9/1000 person-years and subclinical hyperthyroidism was 7.2/1000 person-years.After adjusting potential confounding factors,the multivariable hazard ratios(95%confidence intervals)for subclinical hypothyroidism were 1.00(reference)for almost never,0.53(0.29,0.97)for 1-3 times/week and 0.30(0.10,0.87)for≥4 times/week(P for trend=0.02).It also showed edible mushrooms consumption was inversely associated with subclinical hypothyroidism in obese individuals but not non-obese individuals,the final hazard ratios(95%confidence intervals)were 0.14(0.03,0.73)(P for trend<0.01).Conclusions:This population-based prospective cohort study has firstly demonstrated that higher edible mushrooms consumption was significantly associated with lower incidence of subclinical hypothyroidism among general adult population,especially in obese individuals.

Effects of glucagon-like peptide-1 receptor agonists on glucose excursion and inflammation in overweight or obese type 2 diabetic patients

BACKGROUND Currently,the lack of comparative studies between weekly and daily formulations of glucagon-like peptide-1 receptor agonists(GLP-1RAs)for glucose excursion is worth investigation.AIM To investigate the effects of weekly and daily formulations of GLP-1RA on glucose excursion and inflammation in overweight and obese patients with type 2 diabetes.METHODS Seventy patients with type 2 diabetes mellitus who were treated at our hospital between January 2019 and January 2022 were enrolled in this retrospective analysis.All patients were treated with metformin.We evaluated changes in blood glucose levels and a series of important indicators in patients before and after treatment with either a weekly or daily preparation of GLP-1RA(group A;n=33 and group B;n=37).RESULTS The degree of decrease in the levels of fasting blood glucose,mean blood glucose,mean amplitude of glycemic excursions,total cholesterol,triglycerides,tumor necrosis factor-α,interleukin-6,and high-sensitivity C-reactive protein after treatment in group A was higher than that in group B(P<0.05),whereas the 2-h postprandial blood glucose levels decreased more so in group B than in group A(P<0.001).However,there were no statistically significant differences in the levels of glycated hemoglobin,standard deviation of blood glucose,coefficient of variation,absolute mean of daily differences,percentage of time with 3.9 mmol/L<glucose<10 mmol/L,and high-and low-density lipoproteins between the two groups(P>0.05).The incidence of adverse reactions was significantly lower in group A than in group B(P<0.05).CONCLUSION The effect of the weekly preparation of GLP-1RA in controlling blood glucose levels in the patients,suppressing inflammation,and reducing adverse reactions was significantly higher than that of the daily preparations,which is worthy of clinical promotion.

Chronotropic incompetence is more frequent in obese adolescents and relates to systemic inflammation and exercise intolerance

Background:Adults with obesity may display disturbed cardiac chronotropic responses during cardiopulmonary exercise testing,which relates to poor cardiometabolic health and an increased risk for adverse cardiovascular events.It is unknown whether cardiac chronotropic incompetence(CI)during maximal exercise is already present in obese adolescents and,if so,how that relates to cardiometabolic health.Methods:Sixty-nine obese adolescents(body mass index standard deviation score=2.23±0.32,age=14.1±1.2 years;mean±SD)and 29lean adolescents(body mass index standard deviation score=-0.16±0.84,age=14.0±1.5 years)performed a maximal cardiopulmonary exercise testing from which indicators for peak performance were determined.The resting heart rate and peak heart rate were used to calculate the maximal chronotropic response index.Biochemistry(lipid profile,glycemic control,inflammation,and leptin)was studied in fasted blood samples and during an oral glucose tolerance test within obese adolescents.Regression analyses were applied to examine associations between the presence of CI and blood or exercise capacity parameters,respectively,within obese adolescents.Results:CI was prevalent in 32 out of 69 obese adolescents(46%)and 3 out of 29 lean adolescents(10%).C-reactive protein was significantly higher in obese adolescents with CI compared to obese adolescents without CI(p=0.012).Furthermore,peak oxygen uptake and peak cycling power output were significantly reduced(p<0.05)in obese adolescents with CI vs.obese adolescents without CI.The chronotropic index was independently related to blood total cholesterol(standardized coefficientβ=-0.332;p=0.012)and C-reactive protein concentration(standardized coefficientβ=-0.269;p=0.039).Conclusion:CI is more common in the current cohort of obese adolescents,and is related to systemic inflammation and exercise intolerance.

Importance of proper ventilator support and pulmonary rehabilitation in obese patients with heart failure:Two case reports

BACKGROUND The optimal treatment for heart failure(HF)is a combination of appropriate medications.Controlling the disease using only medical therapy is difficult in patients with HF,severe hypercapnia,and desaturation.These patients should first receive ventilator support followed by pulmonary rehabilitation(PR).CASE SUMMARY We report two cases in which arterial blood gas(ABG)improved and PR was possible with appropriate ventilator support.Two patients with extreme obesity complaining of worsening dyspnea–a 47-year-old woman and a 36-year-old man both diagnosed with HF–were hospitalized because of severe hypercapnia and hypoxia.Despite proper medical treatment,hypercapnia and desaturation resolved in neither case,and both patients were transferred to the rehabilitation department for PR.At the time of the first consultation,the patients were bedridden because of dyspnea.Oxygen demand was successfully reduced once noninvasive ventilation was initiated.As the patients’dyspnea gradually improved to the point where they could be weaned off the ventilator during the daytime,they started engaging in functional training and aerobic exercise.After 4 mo of followup,both patients were able to perform activities of daily living and maintain their lower body weight and normalized ABG levels.CONCLUSION Symptoms of patients with obesity and HF may improve once ABG levels are normalized through ventilator support and implementation of PR.
