Evaluation of Mandibular Deprogramming Using TENS (Transcutaneous Electrical Nerve Stimulation) in Patients at the Specialty Clinic of the Juarez Autonomous University of Tabasco from 2022 to 2024

Temporomandibular disorders (TMD) negatively affect quality of life, causing pain and restricted jaw movements. This study evaluates the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS) on TMD patients before orthodontic treatment at the Juarez Autonomous University of Tabasco. A quantitative, quasi-experimental study was conducted with 30 patients who met the inclusion criteria: aged 18 to 65 years, with TMJ pain symptoms, diagnosed with temporomandibular disorders using the Helkimo index, and who had provided informed consent for the study. The range of mandibular movement and the Visual Analog Scale (VAS) were measured to record values before therapy. The electrodes of the TENS therapy were positioned on both sides of the jaw in the preauricular area and the masseter muscle, the therapy was administered for 40 minutes, utilizing a frequency of 2 - 4 Hz and a pulse duration of 300 microseconds. Following this, the range of mandibular movement and the VAS were reassessed to evaluate the outcomes., significantly improved maximum mouth opening (37.7 ± 6.4 mm to 44.6 ± 5.88 mm), right laterality (3.86 ± 1.57 mm to 5.43 ± 1.21 mm), left laterality (3.13 ± 1.63 mm to 4.53 ± 1.61 mm), protrusion (4.01 ± 1.7 mm to 5.36 ± 1.32 mm), and pain perception (4.56 ± 2.045 to 2.03 ± 1.5) (P < 0.01). TENS therapy enhances mandibular movement and reduces pain, making it a well-tolerated, non-invasive complementary treatment for TMD.

A novel saliva-based miRNA profile to diagnose and predict oral cancer

Oral cancer (OC) is the most common form of head and neck cancer. Despite the high incidence and unfavourable patient outcomes, currently, there are no biomarkers for the early detection of OC. This study aims to discover, develop, and validate a novel saliva-based microRNA signature for early diagnosis and prediction of OC risk in oral potentially malignant disorders (OPMD).The Cancer Genome Atlas (TCGA) miRNA sequencing data and small RNA sequencing data of saliva samples were used to discover differentially expressed miRNAs. Identified miRNAs were validated in saliva samples of OC (n=50), OPMD (n=52), and controls(n=60) using quantitative real-time PCR. Eight differentially expressed miRNAs (miR-7-5p, miR-10b-5p, miR-182-5p, miR-215-5p,miR-431-5p, miR-486-3p, miR-3614-5p, and miR-4707-3p) were identified in the discovery phase and were validated. The efficiency of our eight-miRNA signature to discriminate OC and controls was:area under curve (AUC):0.954, sensitivity:86%, specificity:90%,positive predictive value (PPV):87.8%and negative predictive value (NPV):88.5%whereas between OC and OPMD was:AUC:0.911,sensitivity:90%, specificity:82.7%, PPV:74.2%and NPV:89.6%. We have developed a risk probability score to predict the presence or risk of OC in OPMD patients. We established a salivary miRNA signature that can aid in diagnosing and predicting OC,revolutionising the management of patients with OPMD. Together, our results shed new light on the management of OC by salivary miRNAs to the clinical utility of using miRNAs derived from saliva samples.

Risk Groups and Mortality in Patients with SARS-CoV-2 from Family Medicine Unit No. 43 in Southeastern Mexico

SARS-CoV-2 infection is a viral disease that causes respiratory infections that can cause multiple complications. Patients with adjacent morbidities have a higher chance of complications and mortality. The National Health and Nutrition Survey (ENSANUT) in 2018 reported that in Mexico, 75.2% of adults aged 20 years and over are overweight and obese, both situations are closely related to the cases reported as severe COVID and even with a higher risk of mortality. The main objective was to evaluate the risk and mortality groups in patients with SARS-CoV-2 from family medicine in the south of México. The study was carried out during the 2020 year, in the Family Medicine Unit No. 43 of Villahermosa, Tabasco, a cross-sectional, retrospective investigation was carried out with an analytical approach, and the sample was obtained using the formula of n for infinite populations that correspond to 215, patients were included who met the selection criteria;3 groups were integrated: DM2, HAS and obesity. Descriptive statistics andχ2 formula were used, using the SPSS version 25 Windows program. The female gender presented the highest number of infections 122 (56.7%) and mortality: 5 (2.32%), obesity comorbidity presented the highest number of infections: 194 (90.2%), HAS: 153 (71.2%), and MD: 44 (20.46%). Complications were observed in 23 (10.69%), distributed in: SIRA: 7 (3.3%), multiple organ failure: 6 (2.8%), heart failure: 6 (2.8%) and pneumonia 4 (1.9%). The observed mortality was 8 (3.72%). The comorbidities of patients with the highest mortality were: SAH: 6 (75%) (χ2 = 9.169;df = 1;p = 0.010) and obesity: 6 (75%) (χ2 = 9.169;df = 1;p = 0.010). The group with the highest risk for SARS-CoV-2 was patients with overweight/obesity comorbidities. Mortality was 3.7%. The patients who died had at least one or more comorbidities. The main complications were ARIS, heart failure, and multiple organ failure.

Impacts of fighting against COVID-19 on critical care nurses'psychological and physical health:a literature review

Objective:To provide insight into the effects of the coronavirus disease(COVID-19)pandemic on the physical and psychological health of critical care nurses in adult units.Methods:A systematic search through the CINAHL,MEDLINE,and EMbase databases were performed.Studies that addressed“critical care nurses,”“COVID-19,”“physical effect,”and“psychological effect”from different perspectives were reviewed.Results:A total of 42 ar ticles were reviewed based on 2 aspects:critical care nurses'psychological and physical health.Negative emotions were the most common conditions:fear,anxiety,depression,and post-traumatic stress disorder(PTSD).Burnout,falling ill and having thoughts of self-harm,fatigue,physical burden,sleeping disorders,and chronic work overload also adversely affected the nurses'health.The nurses'health deteriorated because of the changes in the unfamiliar working environment and processes,colossal workload and chronic exhaustion,worries about themselves and their families,social response,and witnessing the death toll.Conclusions:Critical care nurses experienced adverse effects of the institutional reaction,social response,and individuals'reply to the COVID-19 pandemic upon their psychological and physical health.Suppor ting services and preparation for other unprecedented situations should be sustainably available.

The Fifth Plenary Session of the 19th CPC Central Committee called for adherence to a systemic approach to establishing a highquality development mode that is more efficient,equitable,sustainable and secure.Maintaining resource reserves and mitigating environmental pollution under the premise of food security is a major science issue for China’s sustainable development.

Rhinoplasty in Cleft Lip and Palate

Various surgical techniques and approaches have been described to repair cleft nose deformities. It is necessary to consider that since it is a congenital deformity, surgical management must consider the patient’s growth process, as well as the healing itself from the surgery. The present study aims to evaluate an alternative solution to secondary rhinology, aesthetic, and functional alterations to unilateral or bilateral cleft lift palate to minimize deformities and ensure good results. 11 patients were studied between 1995 to 2002, ten male and one female. In 8 cases, the patients had a history of cleft lip and palate on the left side, 2 patients with cleft lift palate on the right, and 1 patient with bilateral cleft lip and palate. 100% of the patients increased their naso-labial angle. This improved their appearance and structure, starting from a preoperative arithmetic mean of 39 degrees to a postoperative arithmetic mean of 96 degrees. Such intervention increased the naso-labial angle by 57 degrees. At the base of the nose, it was possible to improve the inclination of the alar line (line B) in 10 of the cases with a variation of 2 to 3 mm in relation to the perpendicular line A and only one case remained with the same inclination.

Pancreatic Pseudocyst Rupture: Cause of Acute Abdomen

Case report of a 23-year-old male patient with a pancreatic pseudocyst, initially was treated by the Interventional Radiology service by placing percutaneous drainage with poor evolution, abruptly presented abdominal pain, Systemic Inflammatory Response Syndrome and peritoneal irritation, so an urgent exploratory laparotomy was performed with a finding of rupture of the pancreatic pseudocyst into the abdominal cavity. He presented septic shock and died in the immediate postoperative period. Computerized Axial Tomography represents the ideal diagnostic method. Spontaneous rupture is extremely rare and requires urgent surgical intervention.

Biomarkers of Stress and Inflammation in Assessing the Quality of Welfare of Conditioned Vaquejada Horses

In recent decades, the intensity of training and equestrian competitions has significantly increased, thus the assessment of the well-being of the equine athlete has become essential in all equestrian modalities. The aim of this study was to ascertain whether equine athletes submitted to a vaquejada simulation test (VqST), comprised of three races, presented changes in blood biomarkers related to stress and health status. Fourteen healthy Quarter Horses, used as pull horses in this equestrian modality, were evaluated. Ten animals were submitted to the VqST and the remaining four were used as a control group. Blood samples were collected pre-test (during fast), immediately after, and at 1, 4 and 24 hours of recovery. The assessed blood biomarkers included cortisol, interleukin (IL)-6, IL-1β, iron, urea, creatinine, and gamma-glutamyl transferase (GGT) concentrations and results were analyzed using One Way ANOVA (time) with the SigmaStat 13.0 software. No differences between sample times were detected in both groups (p > 0.05) and no differences were found between groups (p > 0.05). The results suggest that all horses were well conditioned for the level of effort imposed by the three vaquejada races. The adaptation to physical exercise may enable the regulation of the acute response to stress in the tissues involved in the exercises, with no differences being observed in stress and health biomarkers, such as IL-6, IL-1β and cortisol. In conclusion, well-conditioned vaquejada horses exhibit a balanced regulation of biological processes, which contributes an increased athletic longevity and better quality of athletic life.

Modified (2+1)-dimensional displacement shallow water wave system and its approximate similarity solutions

Recently, a new （2＋1）-dimensional shallow water wave system, the （2＋1）-dlmenslonal displacement shallow water wave system （2DDSWWS）, was constructed by applying the variational principle of the analytic mechanics in the Lagrange coordinates. The disadvantage is that fluid viscidity is not considered in the 2DDSWWS, which is the same as the famous Kadomtsev-Petviashvili equation and Korteweg-de Vries equation. Applying dimensional analysis, we modify the 2DDSWWS and add the term related to the fluid viscidity to the 2DDSWWS. The approximate similarity solutions of the modified 2DDSWWS （M2DDSWWS） is studied and four similarity solutions are obtained. For the perfect fluids, the coefficient of kinematic viscosity is zero, then the M2DDSWWS will degenerate to the 2DDSWWS.

Simulation on the Conductivity of Charging Stock with Percolation Structure in the Submerged Arc Furnace

Based on the fractal geometry, a new way for selecting material burden ratio and size distribution, named physical design of burden, which is different from stoichiometric weight of carbon burden, would play a more important role in the operation of submerged arc furnace process. Cold simulation investigation was carried out to find how the fraction and size of metal balls affects the specific conductivity of charge mixture, by applying the percolation structure theory. A parameter equation, s/s=A(F-Fc)v, was suggested to calculate the specific conductivity of the charge mixture.

Neuropathic pain-like symptoms and pre-surgery radiographic severity contribute to patient satisfaction 4.8 years post-total joint replacement

AIM To investigate a comprehensive range of factors that contribute to long-term patient satisfaction post-total joint replacement(TJR) in people who had undergone knee or hip replacement for osteoarthritis.METHODS Participants(n = 1151) were recruited from Nottinghamshire post-total hip or knee replacement. Questionnaire assessment included medication use, the pain-DETECT questionnaire(PDQ) to assess neuropathic pain-like symptoms(NP) and TJR satisfaction measured on average 4.8 years post-TJR. Individual factors were tested for an association with post-TJR satisfaction, before incorporating all factors into a full model. Data reduction was carried out using LASSO and receiveroperator characteristic(ROC) curve analysis was used to quantify the contribution of variables to post-TJR satisfaction.RESULTS After data reduction, the best fitting model for post-TJR satisfaction included various measures of pain, history of revision surgery, smoking, pre-surgical X-ray severity, WOMAC function scores and various comorbidities. ROC analysis of this model gave AUC = 0.83(95%CI: 0.80-0.85). PDQ scores were found to capture much of the variation in post-TJR satisfaction outcomes: AUC = 0.79(0.75-0.82). Pre-surgical radiographic severity was associated with higher post-TJR satisfaction: OR_(satisfied) = 2.06(95%CI: 1.15-3.69), P = 0.015.CONCLUSION These results highlight the importance of pre-surgical radiographic severity, post-TJR function, analgesic medication use and NP in terms of post-TJR satisfaction. The PDQ appears to be a useful tool in capturing factors that contribute to post-TJR satisfaction.

A Coupled Hybrid Lattice: Its Related Continuous Equation and Symmetries

The hybrid lattice, known as a discrete Korteweg-de Vries (KdV) equation, is found to be a discrete modified Korteweg-de Vries (mKdV) equation in this paper. The coupled hybrid lattice, which is pointed to be a discrete coupled KdV system, is also found to be discrete form of a coupled mKdV systems. Delayed differential reduction system and pure difference systems are derived from the coupled hybrid system by means of the symmetry reduction approach. Cnoidal wave, positon and negaton solutions for the coupled hybrid system are proposed.

以便秘和腹泻为主的肠易激综合征与5-羟色胺信号改变

Background &Aims: Evidence suggests that postprandial platelet-depleted plasma 5-hydroxytryptamine (5-HT) concentrations may be abnormal in irritable bowel syndrome (IBS). However, interpretation of the data has been hampered by the variable methodology and rather small numbers used in previous studies. Therefore, the aim of this study was to measure concentrations of platelet-depleted plasma 5-HT and its metabolite 5-HIAA under fasting and fed conditions in a large group of patients with diarrhea-predominant (d-) and constipation-predominant (c-) IBS, compared with controls. The ratio of plasma 5-HIAA:5-HT and platelet stores was also assessed. Methods: Twenty-nine c-IBS patients (aged, 19-53 years), 55 d-IBS patients (aged, 19-52 years), and 35 healthy volunteers (aged, 18-46 years) had platelet-depleted plasma 5-HT/5-HIAA concentrations measured using reverse-phase, high-performance liquid chromatography with fluorimetric detection before and after a standard meal. Results: d-IBS patients had raised platelet-depleted plasma 5-HT concentrations under fasting and fed conditions (P < .05). However, the postprandial relative to fasting concentration was similar to controls. In contrast, c-IBS patients failed to show an increase in platelet-depleted plasma 5-HT concentration with meal ingestion compared with controls (P < .01). c-IBS was associated with decreased 5-HIAA (P < .01) but normal 5-HIAA:5-HT ratio and d-IBS with normal 5-HIAA concentrations but reduced 5-HIAA:5-HT ratio (P < .005). c-IBS but not d-IBS patients had increased platelet 5-HT. Conclusions: These results support the concept that d-IBS is characterized by reduced 5-HT reuptake, whereas impaired release may be a feature of c-IBS. These results also provide a rational basis for current pharmacologic approaches involving modulation of different 5-HT receptors in c-and d-IBS.

极早早产儿6岁时的神经和发育障碍

BACKGROUND: Birth before 26 weeks of gestation is associated with a high prev alence of neurologic and developmental disabilities in the infant during the fir st two years of life. METHODS: We studied at the time of early school age childr en who had been born at 25 or fewer completed weeks of gestation in the United K ingdom and Ireland in 1995. Each child had been evaluated at 30 months of age. T he children underwent standardized cognitive and neurologic assessments at six y ears of age. Disability was defined as severe (indicating dependence on caregive rs), moderate, or mild according to predetermined criteria. RESULTS: Of 308 surv iving children, 241 (78 percent) were assessed at a median age of six years and four months; 160 classmates delivered at full term served as a comparison group. Although the use of test reference norms showed that cognitive impairment (defi ned as results more than 2 SD below the mean) was present in 21 percent of the c hildren born extremely preterm (as compared with 1 percent in the standardized d ata), this value rose to 41 percent when the results were compared with those fo r their classmates. The rates of severe, moderate, and mild disability were 22 p ercent, 24 percent, and 34 percent, respectively; disabling cerebral palsy was p resent in 30 children (12 percent). Among children with severe disability at 30 months of age, 86 percent still had moderate to severe disability at 6 years of age. In contrast, other disabilities at the age of 30 months were poorly pre dictive of developmental problems at 6 years of age. CONCLUSIONS: Among extremel y preterm children, cognitive and neurologic impairment is common at school age. A comparison with their classroom peers indicates a level of impairment that is greater than is recognized with the use of standardized norms.

比较咪达唑仑含服与安定直肠给药紧急治疗儿童癫痫发作的安全性和有效性:一项随机对照试验

Background: Rectal diazepam and buccal midazolam are used for emergency treatment of acute febrile and afebrile (epileptic) seizures in children. We aimed to compare the safety and efficacy of these drugs. Methods: A multicentre, randomised controlled trial was undertaken to compare buccal midazolam with rectal diazepam for emergency-room treatment of children aged 6 months and older presenting to hospital with active seizures and without intravenous access. The dose varied according to age from 2.5 to 10 mg. The primary endpoint was therapeutic success: cessation of seizures within 10 min and for at least 1 hour, without respiratory depression requiring intervention. Analysis was per protocol. Findings: Consent was obtained for 219 separate episodes involving 177 patients, who had a median age of 3 years (IQR 1-5) at initial episode. Therapeutic success was 56%(61 of 109) for buccal midazolam and 27%(30 of 110) for rectal diazepam (percentage difference 29%, 95%CI 16-41). Analysing only initial episodes revealed a similar result. The rate of respiratory depression did not differ between groups. When centre, age, known diagnosis of epilepsy, use of antiepileptic drugs, prior treatment, and length of seizure before treatment were adjusted for with logistic regression, buccal midazolam was more effective than rectal diazepam. Interpretation: Buccal midazolam was more effective than rectal diazepam for children presenting to hospital with acute seizures and was not associated with an increased incidence of respiratory depression.

Mechanical Properties of Al_2O_3/Cr_3C_2/(W,Ti)C Ceramic Composites with Y_2O_3 Addition

Ceramic composites Al_2O_3/(W, Ti)C/Cr_3C_2 with different contents of Cr_3C_2 and (W, Ti)C particles, and with the additive Y_2O_3, were fabricated with hot-pressing technique at 1700 ℃ under 28 MPa pressure for 30 min in N_2 atmosphere. The mechanical properties were tested, and the microstructure was investigated by environment scanning electron microscope (ESEM), transmission electron microscope (TEM), energy dispersive analysis using X-ray (EDAX) and optical microscope (OM). Results indicate that the incorporation of Cr_3C_2 and (W,Ti)C particles can suppress the grain growth of the others, and the toughening and strengthening effects mainly originate from nano-particles, dispersion toughening and solidification strengthening. The multiphase composite ceramic material Al_2O_3/10%Cr_3C_2/20%(W,Ti)C shows good mechanical properties, especially the fracture toughness increases from 4.0 MPa·m 1/2 (Monolithic Al_2O_3 ceramic) to 8.92 MPa·m 1/2, the flexural strength from 260～340 MPa (Monolithic Al_2O_3 ceramic) to 496 MPa, due to incorporation of the suitable contents of Cr_3C_2 and (W,Ti)C particles.

New models of adipogenic differentiation highlight a cell-autonomous response to temperature

Temperature is a key regulator of brown adipose tissue(BAT)function,acting through central sensory inputs to influence metabolism and energy storage.Although animal models have produced a wealth of information on the pathways,effectors and responses mediating the physiological response of adipose tissue to temperature in vivo,the use of cell culture models now offers evidence of an additional cell-autonomous response to temperature changes,in the absence of neural input.In particular,stem cell models provide new insight into the regulation of adipogenic differentiation and the induction of browning features in vitro.Here the basis for adipogenic responsiveness to low temperature is discussed,together with different human cell models available to outline the benefits of cell-based approaches for future BAT research.
