Association between childhood obesity and gut microbiota:16S rRNA gene sequencing-based cohort study

BACKGROUND This study aimed to identify characteristic gut genera in obese and normal-weight children(8-12 years old)using 16S rDNA sequencing.The research aimed to provide insights for mechanistic studies and prevention strategies for childhood obesity.Thirty normal-weight and thirty age-and sex-matched obese children were included.Questionnaires and body measurements were collected,and fecal samples underwent 16S rDNA sequencing.Significant differences in body mass index(BMI)and body-fat percentage were observed between the groups.Analysis of gut microbiota diversity revealed lowerα-diversity in obese children.Differences in gut microbiota composition were found between the two groups.Prevotella and Firmicutes were more abundant in the obese group,while Bacteroides and Sanguibacteroides were more prevalent in the control group.AIM To identify the characteristic gut genera in obese and normal-weight children(8-12-year-old)using 16S rDNA sequencing,and provide a basis for subsequent mechanistic studies and prevention strategies for childhood obesity.METHODS Thirty each normal-weight,1:1 matched for age and sex,and obese children,with an obese status from 2020 to 2022,were included in the control and obese groups,respectively.Basic information was collected through questionnaires and body measurements were obtained from both obese and normal-weight children.Fecal samples were collected from both groups and subjected to 16S rDNA sequencing using an Illumina MiSeq sequencing platform for gut microbiota diversity analysis.RESULTS Significant differences in BMI and body-fat percentage were observed between the two groups.The Ace and Chao1 indices were significantly lower in the obese group than those in the control group,whereas differences were not significant in the Shannon and Simpson indices.Kruskal-Wallis tests indicated significant differences in unweighted and weighted UniFrac distances between the gut microbiota of normal-weight and obese children(P<0.01),suggesting substantial disparities in both the species and quantity of gut microbiota between the two groups.Prevotella,Firmicutes,Bacteroides,and Sanguibacteroides were more abundant in the obese and control groups,respectively.Heatmap results demonstrated significant differences in the gut microbiota composition between obese and normal-weight children.CONCLUSION Obese children exhibited lowerα-diversity in their gut microbiota than did the normal-weight children.Significant differences were observed in the composition of gut microbiota between obese and normal-weight children.

Association of preschool children behavior and emotional problems with the parenting behavior of both parents

BACKGROUND Parental behaviors are key in shaping children’s psychological and behavioral development,crucial for early identification and prevention of mental health issues,reducing psychological trauma in childhood.AIM To investigate the relationship between parenting behaviors and behavioral and emotional issues in preschool children.METHODS From October 2017 to May 2018,7 kindergartens in Ma’anshan City were selected to conduct a parent self-filled questionnaire-Health Development Survey of Preschool Children.Children’s Strength and Difficulties Questionnaire(Parent Version)was applied to measures the children’s behavioral and emotional performance.Parenting behavior was evaluated using the Parental Behavior Inventory.Binomial logistic regression model was used to analyze the association between the detection rate of preschool children’s behavior and emotional problems and their parenting behaviors.RESULTS High level of parental support/participation was negatively correlated with conduct problems,abnormal hyperactivity,abnormal total difficulty scores and abnormal prosocial behavior problems.High level of maternal support/participation was negatively correlated with abnormal emotional symptoms and abnormal peer interaction in children.High level of parental hostility/coercion was positively correlated with abnormal emotional symptoms,abnormal conduct problems,abnormal hyperactivity,abnormal peer interaction,and abnormal total difficulty scores in children(all P<0.05).Moreover,paternal parenting behaviors had similarly effects on behavior and emotional problems of preschool children compared with maternal parenting behaviors(all P>0.05),after calculating ratio of odds ratio values.CONCLUSION Our study found that parenting behaviors are associated with behavioral and emotional issues in preschool children.Overall,the more supportive or involved the parents are,the fewer behavioral and emotional problems the children experience;conversely,the more hostile or controlling the parents are,the more behavioral and emotional problems the children face.Moreover,the impact of fathers’parenting behaviors on preschool children’s behavior and emotions is no less significant than that of mothers’parenting behaviors.

Relationship between postoperative rehabilitation style, gastrointestinal function, and inflammatory factor levels in children with intussusception

BACKGROUND Intussusception occurs in children and progresses rapidly.If not treated in time,it may lead to secondary complications such as intestinal perforation,which affect the quality of life and health of children.Surgery is the most common clinical treatment and has a good effect.However,the postoperative prognosis of children with intussusception has a correlation with the postoperative rehabilitation method.Therefore,in this study,we explored the relationship between postopera-tive rehabilitation,gastrointestinal function,and the expression of inflammatory factors in children with intussusception.The medical records of 18 children who were admitted to our hospital for intussusception surgery between October 2022 and May 2024 were retrospectively reviewed.The patients were divided into the routine nursing group(n=6)and rehabilitation training group(n=12)according to the postoperative rehabilitation method.The general data,gastrointestinal function,and inflammatory factor levels of the two groups were statistically analyzed.Pearson correlation analysis of gastrointestinal function,inflammatory factors,and postoperative rehabil-itation was performed.RESULTS We found no significant intergroup differences in sex,age,or disease course(P>0.05).The times to first defecation,bowel sound recovery,and anal exhaust were shorter and inflammatory factor levels were lower in the rehabilitation training group than in the routine nursing group(P<0.05).Pearson correlation analysis showed that gastrin and motilin levels were positively correlated with postoperative rehabilitation(P<0.05).Interleukin(IL)-2,IL-4,IL-6,IL-10,high-sensitivity C-reactive protein,and tumor necrosis factor-αlevels were negatively correlated with postoperative rehabilitation(P<0.05).Gastrointestinal function was positively correlated(P<0.05),and levels of inflammatory factors were negatively correlated with postoperative recovery time(P<0.05).CONCLUSION We found a positive correlation between gastrointestinal function and postoperative rehabilitation training,and a negative correlation between inflammatory factor levels and rehabilitation training in children with intussus-ception.

Adherence to 24-hour movement guidelines in children with mental,behavioral,and developmental disorders:Data from the 2016-2020 National Survey of Children's Health

Background:Adopting a healthy lifestyle during childhood could improve physical and mental health outcomes in adulthood and reduce relevant disease burdens.However,the lifestyles of children with mental,behavioral,and developmental disorders(MBDDs)remains under-described within the literature of public health field.This study aimed to examine adherence to 24-hour movement guidelines among children with MBDDs compared to population norms and whether these differences are affected by demographic characteristics.Methods:Data were from the 2016-2020 National Survey of Children’s Health—A national,population-based,cross-sectional study.We used the data of 119,406 children aged 6-17 years,which included 38,571 participants with at least 1 MBDD and 80,835 without.Adherence to the 24-hour movement guidelines was measured using parent-reported physical activity,screen time,and sleep duration.Results:Among children with MBDDs,20.3%,37.0%,60.7%,and 77.3%met the physical activity,screen time,sleep,and at least 1 of the 24-hour movement guidelines.These rates were lower than those in children without MBDDs(22.8%,46.2%,66.7%,and 83.4%,respectively;all p<0.001).Children with MBDDs were less likely to meet these guidelines(odds ratio(OR)=1.21,95%confidence interval(95%CI):1.13-1.30;OR=1.37,95%CI:1.29-1.45;OR=1.29,95%CI:1.21-1.37;OR=1.45,95%CI:1.35-1.56)than children without MBDDs.Children with emotional disorders had the highest odds of not meeting these guidelines(OR=1.43,95%CI:1.29-1.57;OR=1.48,95%CI:1.37-1.60;OR=1.49,95%CI:1.39-1.61;OR=1.72,95%CI:1.57-1.88)in comparison to children with other MBDDs.Among children aged12-17 years,the difference in proportion of meeting physical activity and screen time guidelines for children with vs.children without MBDD was larger than that among children aged 6-11 years.Furthermore,the above difference of meeting physical activity guidelines in ethnic minority children was smaller than that in white children.Conclusion:Children with MBDDs were less likely to meet individual or combined 24-hour movement guidelines than children without MBDDs.In educational and clinical settings,the primary focus should be on increasing physical activity and limiting screen time in children aged 12-17 years who have MBDDs;and specifically for white children who have MBDDs,increasing physical activity may help.

Objective: To understand the application of echocardiography combined with blood SAA, IL-6, PCT, and CRP detection in the diagnosis and treatment of Kawasaki disease in children. Methods: 56 children with Kawasaki disease were selected as the study subjects as the treatment group, and 54 children with other diseases during the same period were selected as the control group. Echocardiography, blood SAA, IL-6, PCT and CRP were detected before and after treatment to observe the results of the two groups. A database was established to compare the changes of various indicators between the two groups, as well as the application value of each indicator in the clinical diagnosis and treatment of Kawasaki disease, and the pros and cons of the application of each indicator in the diagnosis and treatment of children with Kawasaki disease were analyzed, so as to provide a clearer early warning mechanism for the clinical diagnosis and treatment of children with Kawasaki disease. Results: There was no significant difference in the results of related imaging indexes in the control group before and after treatment (P > 0.05). There was no significant difference in the results of relevant imaging indicators in the treatment group before and after treatment (P > 0.05), except for LMCA (P < 0.05). The comparison of imaging related indicators before and after treatment between the two groups showed that except for no statistically significant difference in LMCA and RMCA before treatment (P > 0.05), all other indicators had statistical significance (P < 0.05). The results of relevant laboratory indexes in control group before and after treatment were statistically significant (P < 0.05). The results of relevant laboratory indexes before and after treatment in the treatment group were statistically significant (P < 0.05). The results of relevant laboratory indicators were compared between the two groups, except for the results of SAA, IL-6 and PCT before treatment, which were not statistically significant (P > 0.05), the differences in all other indicators were statistically significant (P Conclusion: The combination of echocardiography with blood SAA, IL-6, PCT, and CRP detection can establish the optimal evaluation plan for accurate and effective diagnosis, treatment, and prognosis of Kawasaki disease in children, providing more accurate and reliable diagnostic and treatment methods and laboratory data for clinical practice, and thus providing strong protection for children’s health.

Analysis of the Effects of Maternal Body Mass Index and Gestational Weight Gain on Maternal and Neonatal Outcomes in Twin Pregnancy

Objective:To investigate the effects of maternal body mass index(BMI)and gestational weight gain on maternal and neonatal outcomes in twin pregnancies.Methods:Five hundred cases of twin pregnancies were divided into a low body weight group(68 cases),a normal weight group(355 cases),an overweight group(65 cases),and an obesity group(12 cases)according to the World Health Organization(WHO)Body Mass Index(BMI)classification guidelines Results:Comparison of weight gain during different pregnancies revealed that pregnant women were mainly of low weight and average weight.The higher the BMI before pregnancy,the higher the incidence of excessive weight gain during pregnancy.The incidences of gestational diabetes mellitus(GDM)and premature rupture of membranes in women with low weight gain were significantly higher than those in women with average weight gain and high weight gain(P<0.05).The incidences of gestational hypertension,preeclampsia,and anemia in women with high weight gain were significantly higher than those in women with low weight gain and average weight gain(P<0.05).The incidence of neonatal birth weight,fetal distress,and macrosomia in the high weight gain group was significantly higher than those in the low weight gain and average weight gain groups(P<0.05).The birth weight of newborns in low-weight gain mothers was significantly lower than that of normal-weight gain mothers(P<0.05).Conclusion:Poor maternal and infant outcomes were common in women with insufficient or excessive weight gain during pregnancy.Therefore,for women with twin pregnancies,weight management is crucial to ensure maternal and infant health.

Benefits of Mindfulness Training on the Mental Health of Women During Pregnancy and Early Motherhood:A Randomized Controlled Trial

Objective This study aimed to evaluate the effects of a mindfulness-based psychosomatic intervention on depression,anxiety,fear of childbirth(FOC),and life satisfaction of pregnant women in China.Methods Women experiencing first-time pregnancy(n=104)were randomly allocated to the intervention group or a parallel active control group.We collected data at baseline(T0),postintervention(T1),3 days after delivery(T2),and 42 days after delivery(T3).The participants completed questionnaires for the assessment of the levels of depression,anxiety,FOC,life satisfaction,and mindfulness.Differences between the two groups and changes within the same group were analyzed at four time points using repeated-measures analysis of variance.Results Compared with the active control group,the intervention group reported lower depression levels at T2(P=0.038)and T3(P=0.013);reduced anxiety at T1(P=0.001)and T2(P=0.003);reduced FOC at T1(P<0.001)and T2(P=0.04);increased life satisfaction at T1(P<0.001)and T3(P=0.015);and increased mindfulness at T1(P=0.01)and T2(P=0.006).Conclusion The mindfulness-based psychosomatic intervention effectively increased life satisfaction and reduced perinatal depression,anxiety,and FOC.

Endoscopic polidocanol foam sclerobanding for the treatment of grade Ⅱ-Ⅲ internal hemorrhoids:A prospective,multi-center,randomized study

BACKGROUND Endoscopic rubber band ligation(ERBL)is a nonsurgical technique for the treatment of symptomatic internal hemorrhoids but is limited by recurrence and post-procedural pain.AIM To evaluate satisfaction,long-term recurrence,and post-procedural pain in managing internal hemorrhoids using a combination of polidocanol foam sclerotherapy and ERBL.METHODS This was a prospective,multicenter,randomized study.A total of 195 consecutive patients diagnosed with grade II-III internal hemorrhoids were enrolled from four tertiary hospitals and randomly divided into a cap-assisted endoscopic polidocanol foam sclerobanding(EFSB)or an ERBL group.All patients were followed-up for 12 months.Symptom-based severity and post-procedural pain were assessed using a hemorrhoid severity score(HSS)and a visual analog scale(VAS).Continuous variables were reported as medians and interquartile range.RESULTS One hundred and ninety-five patients were enrolled,with 98 in the EFSB group.HSS was lower in the EFSB group than in the ERBL group at 8 weeks[4.0(3.0-5.0)vs 5.0(4.0-6.0),P=0.003]and 12-month[2.0(1.0-3.0)vs 3.0(2.0-3.0),P<0.001]of follow-up.The prolapse recurrence rate was lower in the EFSB group at 12 months(11.2%vs 21.6%,P=0.038).Multiple linear regression analysis demonstrated that EFSB treatment[B=-0.915,95%confidence interval(CI):−1.301 to−0.530,P=0.001]and rubber band number(B=0.843,95%CI:0.595-1.092,P<0.001)were negatively and independently associated with the VAS score 24 hours post-procedure.The median VAS was lower in the EFSB group than in the ERBL[2.0(1.0-3.0)vs 3.0(2.0-4.0),P<0.001].CONCLUSION Cap-assisted EFSB provided long-term satisfaction and effective relief from the recurrence of prolapse and pain 24 hours post-procedure.

3'-Deoxyadenosin alleviates methamphetamine-induced aberrant synaptic plasticity and seeking behavior by inhibiting the NLRP3 inflammasome

Methamphetamine addiction is a brain disorder characterized by persistent drug-seeking behavior, which has been linked with aberrant synaptic plasticity. An increasing body of evidence suggests that aberrant synaptic plasticity is associated with the activation of the NOD-like receptor family pyrin domain containing-3(NLRP3) inflammasome. 3′-Deoxyadenosin, an active component of the Chinese fungus Cordyceps militaris, has strong anti-inflammatory effects. However, whether 3′-deoxyadenosin attenuates methamphetamine-induced aberrant synaptic plasticity via an NLRP3-mediated inflammatory mechanism remains unclear. We first observed that 3′-deoxyadenosin attenuated conditioned place preference scores in methamphetamine-treated mice and decreased the expression of c-fos in hippocampal neurons. Furthermore, we found that 3′-deoxyadenosin reduced the aberrant potentiation of glutamatergic transmission and restored the methamphetamine-induced impairment of synaptic plasticity. We also found that 3′-deoxyadenosin decreased the expression of NLRP3 and neuronal injury. Importantly, a direct NLRP3 deficiency reduced methamphetamine-induced seeking behavior, attenuated the impaired synaptic plasticity, and prevented neuronal damage. Finally, NLRP3 activation reversed the effect of 3′-deoxyadenosin on behavior and synaptic plasticity, suggesting that the anti-neuroinflammatory mechanism of 3′-deoxyadenosin on aberrant synaptic plasticity reduces methamphetamine-induced seeking behavior. Taken together, 3′-deoxyadenosin alleviates methamphetamine-induced aberrant synaptic plasticity and seeking behavior by inhibiting the NLRP3 inflammasome.

Serum proteins differentially expressed in gestational diabetes mellitus assessed using isobaric tag for relative and absolute quantitation proteomics

BACKGROUND As a well-known fact to the public,gestational diabetes mellitus(GDM)could bring serious risks for both pregnant women and infants.During this important investigation into the linkage between GDM patients and their altered expression in the serum,proteomics techniques were deployed to detect the differentially expressed proteins(DEPs)of in the serum of GDM patients to further explore its pathogenesis,and find out possible biomarkers to forecast GDM occurrence.METHODS Subjects were divided into GDM and normal control groups according to the IADPSG diagnostic criteria.Serum samples were randomly selected from four cases in each group at 24-28 wk of gestation,and the blood samples were identified by applying iTRAQ technology combined with liquid chromatography-tandem mass spectrometry.Key proteins and signaling pathways associated with GDM were identified by bioinformatics analysis,and the expression of key proteins in serum from 12 wk to 16 wk of gestation was further verified using enzyme-linked immunosorbent assay (ELISA).RESULTS Forty-seven proteins were significantly differentially expressed by analyzing the serum samples between the GDMgravidas as well as the healthy ones. Among them, 31 proteins were found to be upregulated notably and the rest16 proteins were downregulated remarkably. Bioinformatic data report revealed abnormal expression of proteinsassociated with lipid metabolism, coagulation cascade activation, complement system and inflammatory responsein the GDM group. ELISA results showed that the contents of RBP4, as well as ANGPTL8, increased in the serumof GDM gravidas compared with the healthy ones, and this change was found to initiate from 12 wk to 16 wk ofgestation.CONCLUSION GDM symptoms may involve abnormalities in lipid metabolism, coagulation cascade activation, complementsystem and inflammatory response. RBP4 and ANGPTL8 are expected to be early predictors of GDM.

Effect of comprehensive nursing on the quality of life and swallowing function in individuals diagnosed with ischemic stroke

BACKGROUND Ischemic stroke(IS)is a widely recognized disease characterized by high preva-lence,mortality,morbidity,disability,and recurrence rates.It ranks prominently in terms of mortality,constituting 60%-80%of stroke cases.AIM To explore the impact of comprehensive nursing care on the quality of life and swallowing function in individuals diagnosed with IS.METHODS This study comprised 172 patients with IS admitted to our hospital between February 2018 to March 2021.The participants were divided into two groups,namely the control group(n=80)receiving routine care and the research group(n=92)receiving comprehensive care.Various assessment scales,including the standard swallowing function assessment scale(SSA),National Institutes of Health Stroke scale(NIHSS),European stroke scale(ESS),self-rating anxiety scale(SAS),self-rating depression scale(SDS),Barthel index(BI),and the motor func-tion assessment scale(MAS),were employed to evaluate the improvement in swallowing function,neurological deficits,clinical outcomes,anxiety,depression,daily living activities,and motor function before and after care.Furthermore,the study compared the occurrence of adverse reactions during the nursing period,life quality before and after the intervention,rehabilitation compliance,and nursing satisfaction between the two groups.RESULTS After the nursing intervention,the research group exhibited significantly improved SSA and NIHSS scores compared to the control group(P<0.05).Moreover,both groups demonstrated significant reductions in SAS and SDS scores(P<0.05),with the research group showing more obvious advantages(P<0.05).Compared to the control group,the research group displayed significantly better ESS,BI,and MAS scores(P<0.05),coupled with a lower incidence of adverse reactions(P<0.05).Additionally,the research group demonstrated markedly higher levels of life quality,rehabilitation compliance,and nursing satisfaction compared to the control group(P<0.05).CONCLUSION Comprehensive nursing effectively improved swallowing function,quality of life,and patient satisfaction,high-lighting its clinical significance.

Anemia status of infants and young children aged six to thirty-six months in Ma'anshan City:A retrospective study

BACKGROUND Anemia in infants and young children can have long-term effects on cognitive and physical development.In Ma'anshan City,China,there has been growing concern about the prevalence of anemia among children aged 6 to 36 mo.Understanding the factors influencing this condition is crucial for targeted interventions and improving overall child health in the region.AIM To analyze the anemia status and influencing factors of infants and young children aged 6 to 36 mo in Ma'anshan City,China.Providing scientific evidence for reducing the incidence of anemia and improving the health level of children in this age group.METHODS The study encompassed 37698 infants and young children,aged from 6 to 36 mo,who underwent health examinations at the Ma'anshan Maternal and Child Health Hospital from January 2018 to October 2022 were included in the study.Basic information,physical examination,and hemoglobin detection data were collected.Descriptive analysis was used to analyze the prevalence of anemia in children in the region,and univariate analysis was used to analyze the influencing factors of anemia.RESULTS The mean hemoglobin level of infants and young children aged 9 to 36 mo increased with age,and the anemia detection rate decreased with age.The anemia detection rate in rural infants aged 6,9,and 12 mo was higher than that in urban infants.Although the anemia detection rate was higher in 6-mo-old boys than girls,it was higher in 24-mo-old girls than boys.There were statistically significant differences in the anemia detection rates among 9-mo-old and 12-mo-old infants with different nutritional statuses(emaciation,overweight,obese,and normal).Moreover,there were no statistically significant differences in anemia detection rates among infants and young children with different nutritional statuses at other ages.Besides,the anemia detection rates in obese infants aged 9 and 12 mo were higher than those in normal and overweight infants,with statistically significant differences.Finally,there were no statistically significant differences in the anemia detection rates between emaciation infants and those with other nutritional statuses.CONCLUSION The anemia situation among infants and young children aged 6 to 36 mo in Ma'anshan City,China,is relatively prominent and influenced by various factors.Our result shown that attention should be paid to the anemic infant and young child population,with strengthened education and targeted prevention and dietary guidance to help them establish good living habits,improve nutritional status,and reduce the occurrence of anemia to improve children's health levels.

Recognition System for Diagnosing Pneumonia and Bronchitis Using Children’s Breathing Sounds Based on Transfer Learning

Respiratory infections in children increase the risk of fatal lung disease,making effective identification and analysis of breath sounds essential.However,most studies have focused on adults ignoring pediatric patients whose lungs are more vulnerable due to an imperfect immune system,and the scarcity of medical data has limited the development of deep learning methods toward reliability and high classification accuracy.In this work,we collected three types of breath sounds from children with normal(120 recordings),bronchitis(120 recordings),and pneumonia(120 recordings)at the posterior chest position using an off-the-shelf 3M electronic stethoscope.Three features were extracted from the wavelet denoised signal:spectrogram,mel-frequency cepstral coefficients(MFCCs),and Delta MFCCs.The recog-nition model is based on transfer learning techniques and combines fine-tuned MobileNetV2 and modified ResNet50 to classify breath sounds,along with software for displaying analysis results.Extensive experiments on a real dataset demonstrate the effectiveness and superior performance of the proposed model,with average accuracy,precision,recall,specificity and F1 scores of 97.96%,97.83%,97.89%,98.89%and 0.98,respectively,achieving superior performance with a small dataset.The proposed detection system,with a high-performance model and software,can help parents perform lung screening at home and also has the potential for a vast screening of children for lung disease.

Postpartum Hemorrhage: Incidence, Causes and Maternal Outcomes at Muhimbili National Hospital, Tanzania—A Retrospective Descriptive Hospital-Based Study

Worldwide obstetric hemorrhage remains the leading cause of maternal mortality, accounting for over one quarter of maternal deaths. Over half of these deaths occur in Sub-Saharan Africa with mortality rates of 500 - 1000 per 100,000 births, compared to approximately 5 - 10 in developed countries. Over decades in Sub Saharan Africa preventive measures and treatment protocols have been made to reduce maternal mortality caused by PPH. While rates of postpartum hemorrhage have continued to rise, there is a need to evaluate if its etiology and patterns have changed over time. Broad Objective: This study aims at describing trends in incidence, causes and maternal outcomes of Postpartum Hemorrhage at Muhimbili National Hospital for a period of 7 years. Methodology: This is a retrospective descriptive hospital-based study that has included all cases of postpartum hemorrhage at Muhimbili National Hospital, a tertiary hospital in Tanzania from 2014 to 2020. The data was analyzed using SPSS Version 26 and presented using frequency tables, figures and percentages. The trends of postpartum hemorrhage over time were determined using chi-square test and P-value where less than 0.05 was considered statistically significant. Results: Overall, the incidence of postpartum hemorrhage has been fluctuating over the years with minimum of 1.78% and maximum of 2.87% with no statistical significance. Out of 1113 enrolled cases of PPH, 422 (37.9%) were attributed to genital tears followed by uterine atony 285 (25.6%). A statistically significant increase in linear trend was observed in the postpartum hemorrhage cases due to uterine atony, uterine rupture and sub analysis on genital tears (cervical tear). Overall, there was a statistically significant change in trend of maternal outcomes throughout the years, with a P-value < 0.001 and likelihood of complications increasing over time. Conclusion: The trend in the incidence of postpartum hemorrhage has been fluctuating over the years during the study period. The leading cause of postpartum hemorrhage was genital tears, followed by uterine atony with a significant increase in adverse maternal outcomes over the years. Continuous health education to medical personnel to improve timely and proper diagnosis of women in danger of PPH and timely referral, thus improve maternal morbidity and mortality.

Drosophila models used to simulate human ATP1A1 gene mutations that cause Charcot-Marie-Tooth type 2 disease and refractory seizures

Certain amino acids changes in the human Na^(+)/K^(+)-ATPase pump,ATPase Na^(+)/K^(+)transporting subunit alpha 1(ATP1A1),cause Charcot-Marie-Tooth disease type 2(CMT2)disease and refractory seizures.To develop in vivo models to study the role of Na^(+)/K^(+)-ATPase in these diseases,we modified the Drosophila gene homolog,Atpα,to mimic the human ATP1A1 gene mutations that cause CMT2.Mutations located within the helical linker region of human ATP1A1(I592T,A597T,P600T,and D601F)were simultaneously introduced into endogenous Drosophila Atpαby CRISPR/Cas9-mediated genome editing,generating the Atpα^(TTTF)model.In addition,the same strategy was used to generate the corresponding single point mutations in flies(Atpα^(I571T),Atpα^(A576T),Atpα^(P579T),and Atpα^(D580F)).Moreover,a deletion mutation(Atpα^(mut))that causes premature termination of translation was generated as a positive control.Of these alleles,we found two that could be maintained as homozygotes(Atpα^(I571T)and Atpα^(P579T)).Three alleles(Atpα^(A576T),Atpα^(P579)and Atpα^(D580F))can form heterozygotes with the Atpαmut allele.We found that the Atpαallele carrying these CMT2-associated mutations showed differential phenotypes in Drosophila.Flies heterozygous for Atpα^(TTTF)mutations have motor performance defects,a reduced lifespan,seizures,and an abnormal neuronal morphology.These Drosophila models will provide a new platform for studying the function and regulation of the sodium-potassium pump.

C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 pathway as a therapeutic target and regulatory mechanism for spinal cord injury

Spinal cord injury involves non-reversible damage to the central nervous system that is characterized by limited regenerative capacity and secondary inflammatory damage.The expression of the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis exhibits significant differences before and after injury.Recent studies have revealed that the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis is closely associated with secondary inflammatory responses and the recruitment of immune cells following spinal cord injury,suggesting that this axis is a novel target and regulatory control point for treatment.This review comprehensively examines the therapeutic strategies targeting the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis,along with the regenerative and repair mechanisms linking the axis to spinal cord injury.Additionally,we summarize the upstream and downstream inflammatory signaling pathways associated with spinal cord injury and the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis.This review primarily elaborates on therapeutic strategies that target the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis and the latest progress of research on antagonistic drugs,along with the approaches used to exploit new therapeutic targets within the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis and the development of targeted drugs.Nevertheless,there are presently no clinical studies relating to spinal cord injury that are focusing on the C-C motif chemokine ligand 2/C-C motif chemokine receptor 2 axis.This review aims to provide new ideas and therapeutic strategies for the future treatment of spinal cord injury.
