Abstract
Purpose Epigenetic age and inflammatory markers have been proposed as indicators of severity and mortality in patients with COVID-19. Furthermore, they have been associated with the occurrence of neurological symptoms, psychiatric manifestations, and cognitive impairment. Therefore, we aimed to explore the possible associations between epigenetic age, neuropsychiatric manifestations and inflammatory markers (neutrophil-lymphocyte ratio [NLR], platelet-lymphocyte ratio [PLR], monocyte-lymphocyte ratio [MLR], and systemic immune-inflammation index [SII]) in healthcare personnel with post-COVID condition. Patients and Methods We applied the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) tests to 51 Mexican healthcare workers with post-COVID-19 condition; we also estimated their epigenetic age using the PhenoAge calculator. Results The participants had a post-COVID condition that lasted a median of 14 months (range: 1-20). High NLR (>1.73) had association with mild cognitive impairment by MMSE (p=0.013). Likewise, high MLR (>0.24) were associated with language domain in MOCA (p=0.046). Low PLR (<103.9) was also related to delayed recall in MOCA (p=0.040). Regarding comorbidities, hypertension was associated with SII (p=0.007), overweight with PLR (p=0.047) and alcoholism was associated with MLR (p=0.043). Interestingly, we observed associations of low PLR (<103.9) and low SII (<1.35) levels with increased duration of post-COVID condition (p=0.027, p=0.031). Likewise, increases in PhenoAge were associated with high levels of SII (OR=1.11, p=0.049), PLR (OR=1.12, p=0.035) and MLR (OR=1.12, p=0.030). Conclusion We observed neurocognitive changes related to inflammatory markers and increases in epigenetic age in healthcare personnel with post-COVID-19 condition. Future research is required to assess mental and physical health in individuals with post-COVID-19 symptoms.

Abstract
INTRODUCTION During the COVID-19 pandemic, several strategies were suggested for the management of the disease, including pharmacological and non-pharmacological treatments such as convalescent plasma (CP). The use of CP was suggested due to the beneficial results shown in treating other viral diseases. OBJECTIVE To determine the efficacy and safety of CP obtained from whole blood in patients with COVID-19. METHODS Pilot clinical trial in patients with COVID-19 from a general hospital. The subjects were separated into three groups that received the transfusion of 400ml of CP (n=23) or 400ml of standard plasma (SP) (n=19) and a non-transfused group (NT) (n=37). Patients also received the standard available medical treatment for COVID-19. Subjects were followed up daily from admission to day 21. RESULTS The CP did not improve the survival curve in moderate and severe variants of COVID-19, nor did it reduce the degree of severity of the disease evaluated with the COVID-19 WHO and SOFA clinical progression scale. No patient had a severe post-transfusion reaction to CP. CONCLUSIONS Treatment with CP does not reduce the mortality of patients even when its administration has a high degree of safety.

Abstract
Latent autoimmune diabetes in adults (LADA) has clinical and metabolic features of type 1 and type 2 diabetes. LADA does not have specific features for its diagnosis apart from autoantibody detection; however, these tests are not affordable in clinical settings. In this cross-sectional study, we analyzed clinical criteria, metabolic control, pharmacological treatment, and diabetic complications in two groups of patients with diabetes -LADA and T2D- in order to identify specific characteristic of these clinical entities. Finally, we evaluated if the estimated glucose disposal rate (eGDR) and age at diagnosis of diabetes could be used as a diagnostic criterion for LADA. Demographic, biochemical, clinical and treatment were measured in 377 individuals with diabetes. The diagnostics of LADA were determined using Glutamic acid decarboxylase autoantibodies levels. Chi-square test or t-Student test were used to establish differences between groups. To identify factors associated with LADA, a logistic regression analysis was used. Finally, a ROC curve was plotted to assess the possible variables as diagnostic criteria for LADA. The 377 patients with diabetes were separated into 59 patients with LADA and 318 patients with T2D. Patients with LADA showed lower fasting glucose values, fewer diabetic complications, younger age at diagnosis of diabetes, higher insulin use, and higher eGDR in comparison to patients with T2D. Both groups had a mean BMI classified as overweight. The ROC evaluated the sensitivity and specificity, this analysis indicated that an age younger than 40.5 years and an eGDR value higher than 9.75 mg/kg/min correlated better with LADA. These parameters could be useful to identify patients suspected to have LADA at the first level of medical care in the population of southeastern Mexico and refer them to a second level of care.

Abstract
BACKGROUND Due to the wide spread of SARS-CoV2 around the world, the risk of death in individuals with metabolic comorbidities has dangerously increased. Mexico has a high number of infected individuals and deaths by COVID-19 as well as an important burden of metabolic diseases; nevertheless, reports about features of Mexican individuals with COVID-19 are scarce. The aim of this study was to evaluate demographic features, clinical characteristics and the pharmacological treatment of individuals who died by COVID-19 in the south of Mexico. METHODS We performed an observational study including the information of 185 deceased individuals with confirmed diagnoses of COVID-19. Data were retrieved from medical records. Categorical data were expressed as proportions (%) and numerical data were expressed as mean ± standard deviation. Comorbidities and overlapping symptoms were plotted as Venn diagrams. Drug clusters were plotted as dendrograms. RESULTS The mean age was 59.53 years. There was a male predominance (60.1%). The mean hospital stay was 4.75 ± 4.43 days. The most frequent symptoms were dyspnea (88.77%), fever (71.42%) and dry cough (64.28%). Present comorbidities included diabetes (60.63%), hypertension (59.57%) and obesity (43.61%). The main drugs used for treating COVID-19 were azithromycin (60.6%), hydroxychloroquine (53.0%) and oseltamivir (27.3%). CONCLUSIONS Mexican individuals who died of COVID-19 had shorter hospital stays, higher frequency of shortness of breath, and higher prevalence of diabetes than individuals from other countries. Also, there was a high frequency of off-label use of drugs for their treatment.

Abstract
BACKGROUND Up to now there is not enough evidence that supports the use of electrotherapy in the treatment of Bell's palsy. OBJECTIVE Through a systematic review, we aimed to verify whether the use of electrotherapy is effective for treating Bell's palsy or peripheral paralysis. METHODS Publications were searched in PubMed, EBSCO and Web of Science. The present systematic review included studies that analyzed the electrotherapy as a therapeutic method for treating individuals with Bell's palsy, in order to recover the function of facial muscles. RESULTS Seven studies involving a total of 131 cases and 113 controls were included in this systematic review. In the studies analyzed, patients received electrotherapy combined with other treatments such as hot-wet facial napkins, massages and muscle reeducation. Although the effect of electrotherapy alone was not evaluated, the use of electrotherapy combined with other treatments produced a significant improvement in the individuals evaluated. CONCLUSIONS Due to the diverse methodologies used and the small number of individuals included in the studies, we could not fully prove the efficacy of electrotherapy for treating Bell's Palsy. Future studies with larger samples and homogenous populations should be performed to obtain conclusive results.

Abstract
Metformin (biguanide) is a drug widely used for the treatment of type 2 diabetes. This drug has been used for 60 years as a highly effective antihyperglycemic agent. The search for the mechanism of action of metformin has produced an enormous amount of research to explain its effects on gluconeogenesis, protein metabolism, fatty acid oxidation, oxidative stress, glucose uptake, autophagy and pain, among others. It was only up the end of the 1990s and beginning of this century that some of its mechanisms were revealed. Metformin induces its beneficial effects in diabetes through the activation of a master switch kinase named AMP-activated protein kinase (AMPK). Two upstream kinases account for the physiological activation of AMPK: liver kinase B1 and calcium/calmodulin-dependent protein kinase kinase 2. Once activated, AMPK inhibits the mechanistic target of rapamycin complex 1 (mTORC1), which in turn avoids the phosphorylation of p70 ribosomal protein S6 kinase 1 and phosphatidylinositol 3-kinase/protein kinase B signaling pathways and reduces cap-dependent translation initiation. Since metformin is a disease-modifying drug in type 2 diabetes, which reduces the mTORC1 signaling to induce its effects on neuronal plasticity, it was proposed that these mechanisms could also explain the antinociceptive effect of this drug in several models of chronic pain. These studies have highlighted the efficacy of this drug in chronic pain, such as that from neuropathy, insulin resistance, diabetic neuropathy, and fibromyalgia-type pain. Mounting evidence indicates that chronic pain may induce anxiety, depression and cognitive impairment in rodents and humans. Interestingly, metformin is able to reverse some of these consequences of pathological pain in rodents. The purpose of this review was to analyze the current evidence about the effects of metformin in chronic pain and three of its comorbidities (anxiety, depression and cognitive impairment).

Abstract
BACKGROUND Circulating cell-free mitochondrial DNA (cf-mtDNA) fragments in blood plasma have been reported in patients with schizophrenia (SZ). Although the relationship of cf-mtDNA to the cognitive status of patients with SZ has not yet been explored, it is known that cognitive impairment in SZ compromises the functional and social capacity of these patients and diminishes their quality of life. In this sense, the assessment of the severity of cognitive impairment in a Mexican population with SZ and its association with cf-mtDNA levels in blood plasma may provide the possibility of using cf-mtDNA as a biomarker to determine the status of the disease and the possible ensuing changes over time. METHODS Subjects for a case-control study will be recruited. cf-mtDNA obtained from blood plasma will be quantified by real-time polymerase chain reaction, using melting curve technology with SYBR green as amplification marker. Patients with SZ will be grouped into those with severe, mild, and no cognitive impairment according to Montreal Cognitive Assessment scale scores, to determine differences between cognitive performance and cf-mtDNA levels in blood plasma. ETHICS AND COMMUNICATION This study has been approved by the ethics and investigation committees of the High Specialty Regional Hospital of Mental Health (Hospital Regional de Alta Especialidad de Salud Mental); project No. HRAESM/DG/RP/1128/2018. We plan to communicate our research findings in scientific conferences and in peer-reviewed journals. CONCLUSION It is known that cognitive dysfunction provokes negative effects in an SZ patient´s life. This project aims to provide better knowledge about the role of cf-mtDNA in the pathogenesis of cognitive impairment in SZ, as an attempt to achieve improvements to the existing treatments, thereby helping to prevent major cognitive deterioration.

Abstract
BACKGROUND It is accepted that there is a genetic factor that influences the risk of suicidal behavior. The catechol-O-methyltransferase (COMT) gene, especially the Val108/158Met polymorphism, has been associated with suicide; however, no conclusive outcome has been attained. Therefore, the aim of the present study was to assess the role of COMT Val108/158Met in suicidal behavior throughout an updated meta-analysis. METHODS We performed an online search using PubMed and Web of Science (up to March 2017). Our systematic review included case-control studies of individuals who attempted suicide and completed suicide. We tested allelic, homozygous, heterozygous, dominant, and recessive inheritance models. The meta-analysis was performed in accordance with the statement of Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS The meta-analysis comprised 17 studies, which included 3,282 cases and 3,774 controls, and showed that when evaluating the overall population, the Val108/158Met polymorphism of COMT was not associated with suicidal behavior in any of the inheritance models; however, the subanalyses showed that this polymorphism exhibits a risk factor in males and a protective effect in females. Additionally, it conveyed a risk factor in Asian populations when using the allelic (OR 1.25; CI: 1.04-1.51) and recessive models (OR 1.32; CI: 1.03-1.68). CONCLUSION Our updated meta-analysis suggests a possible association between COMT Val108/158Met and suicidal behavior in Asian populations. However, in view of the small number of studies, these results should be considered exploratory. We recommend that more studies be performed with larger samples.

Abstract
Suicide is the second cause of death in youth population. The aim of the present study was to analyze demographic characteristics and suicide methods used, as well as to identify gender differences among Mexican children and adolescents (aged 10-17 years) that committed suicide. Between January 2003 and December 2013, 167 suicides of children and adolescents between 10 and 17 years of age were documented by the Secretary of Health of the state of Tabasco, Mexico. All sociodemographic characteristics were compared according to gender. Our sample included 67.7% males and 32.3% females (male to female 2.1:1). The predominant marital status was single (89.6%) and hanging (93.7%) was the principal method of suicide used. Both female and male adolescents were predominantly students (50%); however, female adolescents were more frequently married (17%) and were housewives (26.4%). Our results identified that hanging is the principal suicide method used by children and adolescents in Mexican population; we also detected main gender differences in terms of poisoning/drug toxicity as the method used, occupation and marital status. These results should be taken into consideration when designing suicide prevention programs due to the differences found by gender.

Abstract
OBJECTIVE In recent years, suicide in children and adolescents has increased considerably, becoming the second cause of death in this age group. Therefore, the aim of this study was to identify characteristics and factors that could precipitate deaths by suicide in children and adolescents. METHODS Using the psychological autopsy method, we studied 28 suicide cases of children and adolescents between 10 and 17 years old. Socio-demographic factors, characteristics of the suicide and family history were documented. RESULTS The proportion of deaths by suicide was the same in females and males (50% each). Most of the suicides were performed at the child/adolescent's home (78.6%) and no history of previous suicide attempts were registered (85.7%). Also, the majority of suicidal individuals came from a dysfunctional family (60.7%). CONCLUSIONS Our results identified characteristics of children and adolescents that had died by suicide, such as dying at their homes and coming from dysfunctional families. Knowing the characteristics of children and adolescents that had ended their lives by suicide should be considered in future studies to help developing preventive programs and strategies for treating suicidal behaviors in Mexican children and adolescents.

Abstract
Preclinical Research Metformin-dependent mechanisms have been implicated in the antinociceptive effect of some non-steroidal anti-inflammatory drugs (NSAIDs). In this study, the effect of local peripheral or systemic administration of metformin on the local peripheral or systemic antinociception induced by indomethacin, ketorolac and metamizole was assessed in the rat carrageenan-induced thermal hyperalgesia model. Rats were injected with carrageenan (1%, 50 µl) into the right hindpaw which reduced paw withdrawal latency, a measure of thermal hyperalgesia. Local peripheral or systemic administration of indomethacin, ketorolac or metamizole dose-dependently reduced carrageenan-induced thermal hyperalgesia. Local peripheral pre-treatment with metformin (800 µg/paw) partially inhibited the anti-hyperalgesic effect of indomethacin (200 µg/paw) and metamizole (200 µg/paw), but not that of ketorolac (200 µg/paw). In contrast, systemic pre-treatment with metformin (200 mg/kg) attenuated the antihyperalgesic effect of metamizole (10 mg/kg), but not that observed with either indomethacin (10 mg/kg) or ketorolac (10 mg/kg). These findings suggest that some but not all NSAIDs have effects mediated by metformin-dependent mechanisms. Drug Dev Res 78 : 98-104, 2017. ©2017 Wiley Periodicals, Inc.

Abstract
BACKGROUND The aim of this case-control study was to explore the association by gender between the HTR2C gene variants and suicidal behavior in a Mexican population. SUBJECTS AND METHODS A total of 183 suicide attempters and 208 healthy volunteers were included in this study. We genotyped five polymorphisms of HTR2C (rs547536, rs2192372, rs4272555, rs6318, and rs2428707), then measured the association by genotype, allele, and haplotype. RESULTS In the female group, we found an association between two polymorphisms of the HTR2C (rs4272555 and rs2428707) and suicide attempts. The C allele of the single-nucleotide polymorphism (SNP) rs4272555 was associated with a decreased risk of suicide attempt (P=0.01, odds ratio =0.26, 95% confidence interval: 0.09-0.79), whereas the G allele of the SNP rs2428707 was associated with an increased risk of suicide attempt (P=0.01, odds ratio =3.68, 95% confidence interval: 1.24-10.90). No significant association was observed between the other polymorphisms studied (rs547536, rs2192372, rs6318) or haplotypes with suicide attempts. CONCLUSION These findings suggest a possible risk factor of the HTR2C gene in the pathology of suicidal behavior in Mexican population. More studies are necessary to confirm this association.
