Abstract
INTRODUCTION Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. METHODS A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. RESULTS A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence. Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. CONCLUSION The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations. Inadequate use of combination therapy was observed. This study underscores the urgent need for targeted interventions addressing cardiovascular risk factors in poor areas to mitigate the burden of CVD.

Abstract
Atherosclerosis is one of the most relevant and prevalent cardiovascular diseases of our time. It is one of the pathological entities that increases the morbidity and mortality index in the adult population. Pathophysiological connections have been observed between atherosclerosis and the gut microbiome (GM), represented by a group of microorganisms that are present in the gut. These microorganisms are vital for metabolic homeostasis in humans. Recently, direct and indirect mechanisms through which GM can affect the development of atherosclerosis have been studied. This has led to research into the possible modulation of GM and metabolites as a new target in the prevention and treatment of atherosclerosis. The goal of this review is to analyze the physiopathological mechanisms linking GM and atherosclerosis that have been described so far. We also aim to summarize the recent studies that propose GM as a potential target in atherosclerosis management.

Abstract
Abstract:
The emergence of the novel coronavirus SARS-CoV-2 has had a significant impact on the population of the world, disrupting healthcare systems around the globe and leading to human and material losses. While different vaccines have been approved in record time, there continues to be a high number of daily new cases and patients face a wide range of presentations of the disease, from asymptomatic to potentially fatal. Therefore, the search for therapeutic agents that can aid in the management and control of the disease has become one of the main goals for researchers and clinicians. As an inflammatory disease, targets for the treatment of COVID-19 have largely involved the immune system. Inflammation has also been associated with mental health disorders, and studies have shown the potential involvement of inflammatory pathways in the pathophysiology of depression. As a consequence, the hypothesis of using antidepressants and other psychotropics for the treatment of COVID-19 has emerged. In this review, we aim to summarize the molecular pathways that could be involved as well as the emergent evidence that has been reported by studies performed since the appearance of SARS-CoV-2 in 2019. While it has been observed that there are potential therapeutic pathways for the use of antidepressants in the treatment of COVID-19, additional studies are needed to evaluate the feasibility, safety, and efficacy of psychotropics in this disease.

Abstract
Background:
Parkinson’s disease (PD) is the second most common neurodegenerative disorder worldwide. The symptoms of PD are characterized not only by motor alterations but also by a spectrum of nonmotor symptoms. Some of these are psychiatric manifestations such as sleep disorders; depression; cognitive difficulties that can evolve into dementia; and symptoms of psychosis, which include hallucinations, illusions, and delusions. Parkinson’s disease psychosis (PDP) occurs in 18%–50% of patients with PD. Treating PDP is challenging because antipsychotic drugs tend to be inefficient or may even worsen the motor symptoms of the disease.
Methods:
This is a narrative review in which an extensive literature search was performed on the Scopus, EMBASE, PubMed, ISI Web of Science, and Google Scholar databases, from inception to August 2021. The terms “Parkinson’s disease psychosis,” “Parkinson psychosis,” “neurodegenerative psychosis,” and “dopamine psychosis” were among the keywords used in the search.
Objective:
current understanding of the molecular mechanisms involved in PDP, as well as recent innovative alternatives for its treatment.
Results:
Recently, views on the etiology of hallucinations and illusions have evolved remarkably. PDP has been cemented as a multifactorial entity that is dependent not only on extrinsic mechanisms but also novel intrinsic mechanisms including genetic factors, neurostructural alterations, functional disruptions, visual processing disturbances, and sleep disorders. Consequently, innovative pharmacological and biological treatments have been proposed. Pimavanserin, a selective 5-HT2A inverse agonist, stands out after its approval for the treatment of PDP-associated hallucinations and illusions.
Conclusion:
Future results from upcoming clinical trials should further characterize the role of this drug in the management of PDP as well as other treatment options with novel mechanisms of action, such as saracatinib, SEP-363856, cannabidiol, electroconvulsive therapy, and transcranial magnetic stimulation.

Abstract
Chronic pain (CP) is a severe clinical entity with devastating physical and emotional consequences for patients, which can occur in a myriad of diseases. Often, conventional treatment approaches appear to be insufficient for its management. Moreover, considering the adverse effects of traditional analgesic treatments, specialized pro-resolving lipid mediators (SPMs) have emerged as a promising alternative for CP. These include various bioactive molecules such as resolvins, maresins, and protectins, derived from ω-3 polyunsaturated fatty acids (PUFAs); and lipoxins, produced from ω-6 PUFAs. Indeed, SPMs have been demonstrated to play a central role in the regulation and resolution of the inflammation associated with CP. Furthermore, these molecules can modulate neuroinflammation and thus inhibit central and peripheral sensitizations, as well as long-term potentiation, via immunomodulation and regulation of nociceptor activity and neuronal pathways. In this context, preclinical and clinical studies have evidenced that the use of SPMs is beneficial in CP-related disorders, including rheumatic diseases, migraine, neuropathies, and others. This review integrates current preclinical and clinical knowledge on the role of SPMs as a potential therapeutic tool for the management of patients with CP.

Abstract
Metabolic syndrome (MS) is a set of cardio-metabolic risk factors that includes central obesity, hyperglycemia, hypertension, and dyslipidemias. The syndrome affects 25% of adults worldwide. The definition of MS has evolved over the last 80 years, with various classification systems and criteria, whose limitations and benefits are currently the subject of some controversy. Likewise, hypotheses regarding the etiology of MS add more confusion from clinical and epidemiological points of view. The leading suggestion for the pathophysiology of MS is insulin resistance (IR). IR can affect multiple tissues and organs, from the classic “triumvirate” (myocyte, adipocyte, and hepatocyte) to possible effects on organs considered more recently, such as the central nervous system (CNS). Mild cognitive impairment (MCI) and Alzheimer’s disease (AD) may be clinical expressions of CNS involvement. However, the association between MCI and MS is not understood. The bidirectional relationship that seems to exist between these factors raises the questions of which phenomenon occurs first and whether MCI can be a precursor of MS. This review explores shared pathophysiological mechanisms between MCI and MS and establishes a hypothesis of a possible MCI role in the development of IR and the appearance of MS.

Abstract
At present, Alzheimer’s disease (AD) and type 2 diabetes mellitus (T2DM) are two highly prevalent disorders worldwide, especially among elderly individuals. T2DM appears to be associated with cognitive dysfunction, with a higher risk of developing neurocognitive disorders, including AD. These diseases have been observed to share various pathophysiological mechanisms, including alterations in insulin signaling, defects in glucose transporters (GLUTs), and mitochondrial dysfunctions in the brain. Therefore, the aim of this review is to summarize the current knowledge regarding the molecular mechanisms implicated in the association of these pathologies as well as recent therapeutic alternatives. In this context, the hyperphosphorylation of tau and the formation of neurofibrillary tangles have been associated with the dysfunction of the phosphatidylinositol 3-kinase and mitogen-activated protein kinase pathways in the nervous tissues as well as the decrease in the expression of GLUT-1 and GLUT-3 in the different areas of the brain, increase in reactive oxygen species, and production of mitochondrial alterations that occur in T2DM. These findings have contributed to the implementation of overlapping pharmacological interventions based on the use of insulin and antidiabetic drugs, or, more recently, azeliragon, amylin, among others, which have shown possible beneficial effects in diabetic patients diagnosed with AD.

Abstract
BACKGROUND Visceral adiposity is related to insulin resistance (IR), a metabolic state considered as a risk factor for other cardiometabolic diseases. In that matter, mathematical indexes such as the visceral adiposity index (VAI) and the lipid accumulation product (LAP) could indirectly assess IR based on visceral adiposity. OBJECTIVE To evaluate the association and diagnostic accuracy of VAI and LAP to diagnose IR in the adult population of Maracaibo city. METHODS This is a cross-sectional descriptive study with multistage sampling. Receiver operating characteristic (ROC) curves were built to determine VAI and LAP cutoff points to predict IR. A set of logistic regression models was constructed according to sociodemographic, psychobiologic, and metabolic variables. RESULTS 1818 subjects were evaluated (51.4% women). The area under the curve (AUC) values for LAP and VAI were 0.689 (0.665-0.714) and 0.645 (0.619-0.670), respectively. Both indexes showed a higher IR risk in the upper tertile in bivariate analysis. However, in the logistic regression analysis for the IR risk, only the 2nd (OR: 1.91; 95% CI: 1.37-2.65; p < 0.01) and 3rd (OR: 5.40; 95% CI: 3.48-8.39; p < 0.01) LAP tertiles showed a significant increase. This behaviour was also observed after adjusting for hs-C-reactive protein (hs-CPR). CONCLUSION Although both indexes show a low predictive capacity in individuals with IR in the Maracaibo city population, the LAP index was more strongly associated with IR.

Abstract
Patients with rheumatoid arthritis (RA) may be classified as seropositive or seronegative according to the presence of autoantibodies. An abnormal B cell phenotype and function could be one of the main components of the immunopathology of seropositive patients; however, there is little information regarding B cell defects in these patients. This study shows a broad characterization of the B cell phenotype and function in patients with seropositive RA. We focused mainly on the evaluation of subsets, the expression of modulatory molecules of cell activation (CD22, FcɣRIIb and FcµR), calcium mobilization, global tyrosine phosphorylation, expression of activation markers, cytokine and immunoglobulin (Ig) production, proliferation and the in-vitro generation of plasma cells. Increased frequency of CD27- IgM- IgD- and CD21- B cells was observed in patients with seropositive RA compared with healthy donors (HD). Decreased expression of CD22 was primarily found in memory B cells of patients with RA regardless of seropositivity. B cells from seropositive patients exhibited normal proliferation, calcium mobilization kinetics and global tyrosine phosphorylation, but showed an increased frequency of CD86+ B cells compared with HD. B cells of seropositive patients secrete less interleukin-10 after in-vitro activation and showed a decreased frequency of plasma cell differentiation and IgM production compared with HD. Our data indicate that patients with seropositive RA have an increased frequency of atypical B cell populations previously associated with chronic activation and antigen exposure. This may result in the observed low responsiveness of these cells in vitro.

Abstract
Aging is a time-dependent inevitable process, in which cellular homeostasis is affected, which has an impact on tissue function. This represents a risk factor for the development of numerous non-transmissible diseases. In consequence, the scientific community continues to search for therapeutic measures capable of improving quality of life and delaying cellular aging. At the center of this research is metformin, a widely used drug in Type 2 Diabetes Mellitus treatment that has a reduced adverse effects profile. Furthermore, there is evidence that this drug has beneficial health effects that go beyond its anti-hyperglycemic properties. Among these effects, its geronto-protection capability stands out. There is growing evidence that points out to an increased life expectancy as well as the quality of life in model organisms treated with metformin. Therefore, there is an abundance of research centered on elucidating the mechanism through which metformin has its anti-aging effects. Among these, the AMPK, mTORC1, SIRT1, FOXO, NF.kB, and DICER1 pathways can be mentioned. Furthermore, studies have highlighted the possibility of a role for the gut microbiome in these processes. The next step is the design of clinical essays that have as a goal evaluating the efficacy and safety of metformin as an anti-aging drug in humans to create a paradigm in the medical horizon. The question being if metformin is, in fact, the new antiaging therapy in humans?

Abstract
At present, the pathologic spectrum of obesity-insulin resistance (IR)-diabetes mellitus (DM) represents not only a pressing matter in public health but also a paramount object of study in biomedical research, as they constitute major risk factors for cardiovascular disease (CVD), and other chronic non-communicable diseases (NCD). Phytotherapy, the use of medicinal herbs (MH) with treatment purposes, offers a wide array of opportunities for innovation in the management of these disorders; mainly as pharmacological research on small molecules accumulates. Several MH has displayed varied mechanisms of action relevant to the pathogenesis of obesity, IR and DM, including immunological and endocrine modulation, reduction of inflammation and oxidative stress (OS), regulation of appetite, thermogenesis and energy homeostasis, sensitisation to insulin function and potentiation of insulin release, among many others. However, the clinical correlates of these molecular phenomena remain relatively uncertain, with only a handful of MH boasting convincing clinical evidence in this regard. This review comprises an exploration of currently available preclinical and clinical research on the role of MH in the management of obesity, IR, and DM.

Abstract
Background Evidence shows that the ageing process is a determining factor in fat distribution, composition, and functionality. The goal of this research was to determine cut-off points for waist circumference according to age in the adult population from Maracaibo city, Venezuela. Methodology The Metabolic Syndrome Prevalence Study is a descriptive, cross-sectional study with multi-stage randomized sampling. In this post-hoc analysis 1902 individuals ≥18 years and from both sexes were evaluated. Waist circumference ROC curves were built for each age group and sex, using metabolic phenotypes for classification. Results 52.2% (n = 992) were women, and the mean age was 38.7 ± 2. Cut-off points obtained for the <30 years age group were: 91 cm for women (Sensitivity: 96,8%, Specificity: 97,7%) and 94 cm for men (Sensitivity:100%, Specificity: 99,2%); for 30-49 years: women 94 cm (Sensitivity: 93.7%, Specificity: 97.1%) and men 95 cm (Sensitivity: 97.3%, Specificity: 100%); for ≥50 years: women 94 cm (Sensitivity: 91.8%, Specificity: 86.7%) and men 101 cm (Sensitivity: 100%, Specificity: 100%). Conclusion The use of specific cut-off points according to age groups is proposed to determine abdominal obesity in Maracaibo city due to the underestimation seen in young people and the overestimation observed in older people when using a unique cut-off point.

Abstract
Background:
Depression is a heavily prevalent mental disorder. Symptoms of depression
extend beyond mood, cognition, and behavior to include a spectrum of somatic manifestations in all
organic systems. Changes in sleep and neuroendocrine rhythms are especially prominent, and disruptions
of circadian rhythms have been closely related to the neurobiology of depression. With the
advent of increased research in chronobiology, various pathophysiologic mechanisms have been
proposed, including anomalies of sleep architecture, the effects of clock gene polymorphisms in
monoamine metabolism, and the deleterious impact of social zeitgebers. The identification of these
chronodisruptions has propelled the emergence of several chronotherapeutic strategies, both pharmacological
and non-pharmacological, with varying degrees of clinical evidence.
Methods:
The fundamental objective of this review is to integrate current knowledge about the role
of chronobiology and depression and to summarize the interventions developed to resynchronize
biorhythms both within an individual and with geophysical time.
Results:
We have found that among the non-pharmacological alternatives, triple chronotherapywhich
encompasses bright light therapy, sleep deprivation therapy, and consecutive sleep phase
advance therapy-has garnered the most considerable scientific interest. On the other hand,
agomelatine appears to be the most promising pharmacological option, given its unique melatonergic
pharmacodynamics.
Conclusions:
Research in chronotherapy as a treatment for depression is currently booming. Novel
interventions could play a significant role in adopting new options for the treatment of depression,
with Tripe Cronotherapy standing out as the most promising treatment.

Abstract
Gonadotrophins are included in oestrous/ovulation synchronization (E/OS) regimens when breeding early in the transitional phase to promote follicular development. However, the time of use has been a matter of debate. Hence, the objective of this study was to determine whether equine and human chorionic gonadotrophins (eCG and hCG, respectively) given 24h before or 24h after concurrent removal of intravaginal progestagen (P4) and prostaglandin (PGF2α) delivery influences pregnancy rate (PR) and/or embryo viability (EV). Relatedly, the influence of gonadotrophin-releasing hormone (GnRH) 5 days post-breeding (dpb) on PR and/or EV was also considered. A prospective randomised control trial was conducted using lactating and non-lactating Alpine breed goats of different parity, average±s.e. age, and bodyweight (3.7±2.6), and (52.5±7), respectively. Goats were time-bred at 48h after P4 removal by laparoscopy (LAI; n=75) or by natural service (NS; n=29) during the early transitional breeding phase in mid-September through mid-December (corresponding to 12:12h daylight/darkness). E/OS used an intravaginal device containing 300mg of P4 for 12±1d. At P4 removal, 2mL of PGF2α was administered IM. Twenty-four hours before (E) or 24h after (L) P4 removal, an IM dose of 1.5mL containing 120IU of eCG and 60IU of hCG was given. A third control (C) group (n=38) was not exposed to gonadotrophins. GnRH analogue was given (n=51) 5 days after insemination, and the remaining goats (n=53) received an IM dose of 2mL of saline solution. PR was evaluated at 18 to 24 (dpb) by non-return to oestrus (NRE), at 30 dpb by pregnancy-specific protein B (PSPB), and at 40 dpb by ultrasound imaging (UI). EV was determined from the difference between pregnancy outcomes for NRE and PSPB, and PSPB and UI. Statistical analysis (JMP/SAS vs.11; SAS Institute Inc.) were obtained using logistic regression. All concomitant variables (i.e. parity, bodyweight, days of P4 exposure, and lactation were not influenced by PR or EV; P>0.07). The overall PR was 71% for LAI and 69% for NS and, as shown in Table 1, was similar (P>0.49) at all times (at 18 to 24, 30, and 40 dpb). Likewise, the breeding procedure did not influence the levels of EV at 30 or 40 dpb. E/OS protocol or the use of GnRH 5 dpb did not affect PR or EV at any of the time points evaluated.

Abstract
Oestrus and ovulation synchronization (E/OS) regimens for fixed-timed breeding are useful when consistently eliciting ovulation. Early synchronization in the reproductive season promotes unreliable oestrus behavioural and physiologic response due to insufficient ovarian priming. In ruminants, equine (eCG) or human chorionic gonadotrophin (hCG) has FSH bioactivity or elicits ovulation, correspondingly. Hence, 120 and 60IU of eCG and hCG, respectively, are included in goat E/OS regimes. This experiment addresses the time when eCG/hCG (CG) is given relative to progestagen (P4) withdrawal and its effect on oestrus and ovulation. Fourteen non-lactating, Alpine breed goats, ranging from 1 to 6 kiddings, averaging±s.d. 3.9±2.0 years of age, and 56.3±5.0kg of bodyweight (BW), and body condition score (BCS) of 2.6±0.2, were evaluated early in the transitional reproductive phase (12h daylight:12h darkness). E/OS was accomplished with 12 day of P4 (200 mg) exposure by intravaginal insert. Three treatments were evaluated: Traditional (T; n=4) did not receive CG and served as the control group; early (E; n=5) received CG 24h before P4 removal; and reverse (R; n=5) received PGF2α 24h before P4 withdrawal as well as CG concurrent with P4 withdrawal. Oestrus response to E/OS was evaluated 24h after breeding using epididymectomized bucks. Ovaries were scanned by transrectal ultrasound (Aloka SSD-500V/7.5-MHz linear array probe) for 4 consecutive days starting with the first i.m. injection of 1.0mL of PGF2α or 1.5mL of CG. Images were digitized (MediCapture™) for later morphometry. The absence of effect (P>0.05) from concomitant variables age, BW, BCS, and parity was ascertained using a logistic regression model (JMP/SAS v15; SAS Institute Inc.). Ovulation, defined as the disappearance of the largest (>7mm) preovulatory follicle on a subsequent observation, was 100, 80, and 100%; and the average±s.e. number of ovulations per goat was 2±0.41, 1±0.32, and 1.3±0.49 (P>0.05). Table 1 summarises follicular size documented of 122 observations of ovulatory areas. Graafian follicle location was not different for left or right ovaries (P>0.05). Oestrus behavioural response to each E/OS treatment (T, E, or L) up to 24h after P4 removal was 50, 80, and 80% (P>0.05), respectively. In summary, oestrus response and ovulation were not affected by the variables studied. In this experience the timing of CG was not relevant.

Abstract
Gonadotrophin-releasing hormone (GnRH) or equine and human chorionic gonadotrophins (eCG and hCG) were evaluated for oestrus/ovulation synchronization (E/OS), as well as the influence of GnRH 5 days post-breeding (dpb) on embryo viability (EV), and progesterone (P4) levels on Day 16 and 30 after laparoscopic AI (LAI) or natural service (NS). Fifty-four lactating/non-lactating Alpine breed goats (average of 3.82±1.2s.d. years of age) of mixed parity were E/OS during the early transitional breeding phase using 12±1 day of 300mg of P4 and 2mL of prostaglandin F2α analogue given at P4 removal. The experiment included a sub-group from a larger study in which a completely randomised design was used. The germane data were arranged as a 2×2×2 factorial. This study focused on goats receiving 120IU of eCG and 60IU of hCG (n=40), or GnRH analogue (n=14) 24h after P4 removal. At 5 dpb, 25 goats received 1mL (IM) of GnRH and the control (n=29) received 1mL of physiologic saline. Goats were time-bred 48h after P4 withdrawal by LAI (n=33) or NS (n=21). Pregnancy was diagnosed at 18 to 24, 30, and 40 dpb by non-return to oestrus, pregnancy-specific protein B, and ultrasound, respectively. EV was evaluated as the difference between pregnancy diagnosis results. Blood serum P4 was evaluated at 5, 16, and 30 dpb. A logistic regression model was used for statistical analysis. Pregnancy rate (PR) for LAI or NS, at 18–24, 30, and 40 days was 73 vs. 76%, 67 vs. 62%, and 64 vs. 67%, respectively (P>0.72). In contrast, when GnRH was used for E/OS, the 5 dpb GnRH influenced EV at 30 days (95 vs. 81%; P=0.06) but not at 40 days (89 vs. 86%; P>0.35), compared with placebo. Similarly, with the exception of PR at 40 days (43 vs. 72%; P=0.05), for the GnRH and eCG/hCG E/OS groups, respectively, PR was not affected (P>0.12) by either E/OS or GnRH 5 dpb or their interaction (P>0.35) at any pregnancy diagnosis (i.e. 18–24, 30, or 40 dpb). Likewise, levels of P4 at 5, 16, and 30 dpb did not affect PR at 18–24, 30, and 40 dpb (P>0.92, 0.71, and 0.11). As shown in Table 1, the level of P4 was not influenced for goats receiving GnRH or placebo at 5, 16, or 30 dpb. The baseline mean P4 blood serum level for goats receiving GnRH 5 dpb differed at 16 but not at 30 dpb (P<0.001).

Abstract
UNLABELLED There is a pressing need to equip youth-serving community organizations to respond to the unique needs of trauma-exposed children. Early prevention measures can be an effective means of redirecting children to self-regulatory healing, while facilitating their transition toward strength-based thriving. Sport can offer a powerful opportunity to reach these children; however there remains little information on how to effectively develop, deliver, evaluate, and sustain trauma-sensitive sport programs in a community context. The purpose of this paper is to outline a case study of integrating sport-based trauma-sensitive practices with BGC Canada's national Bounce Back League program. An interdisciplinary partnership of academic, community, and practice experts used a community-based participatory action research approach, paired with a knowledge translational approach, to guide the process of program development. Mixed methods (e.g., surveys, logbooks, interviews, focus groups, online communications) were used to generate ongoing insights of staff's training experiences, successes and challenges of program implementation, and potential impact of program on club members. Several stages of program development are described, including: (a) collaboratively planning the program; (b) piloting the program to three clubs; (c) adapting the program using pilot insights; (d) expanding the adapted program to ten clubs; and (e) creating opportunities to maintain, sustain, and scale-out practices throughout grant duration and beyond. Lessons learned regarding the leadership team's experiences in terms of developing, adapting, and integrating trauma-sensitive practices in this community context are shared.

Abstract
Modern times have seen depression and cardiovascular disease (CVD) become notorious public health concerns, corresponding to alarming proportions of morbidity, mortality, decreased quality of life, and economic costs. Expanding comprehension of the pathogenesis of depression as an immunometabolic disorder has identified numerous pathophysiologic phenomena in common with CVD, including chronic inflammation, insulin resistance, and oxidative stress. These shared components could be exploited to offer improved alternatives in the joint management of these conditions. Abundant preclinical and clinical data on the impact of established treatments for CVD in the management of depression have allowed for potential candidates to be proposed for the joint management of depression and CVD as immunometabolic disorders. However, a large proportion of the clinical investigation currently available exhibits marked methodological flaws which preclude the formulation of concrete recommendations in many cases. This situation may be a reflection of pervasive problems present in clinical research in psychiatry, especially pertaining to study homogeneity. Therefore, further high-quality research is essential in the future in this regard.

Abstract
Although novel pharmacological options for the treatment of type 2 diabetes mellitus (DM2) have been observed to modulate the functionality of several key organs in glucose homeostasis, successful regulation of insulin resistance (IR), body weight management, and pharmacological treatment of obesity remain notable problems in endocrinology. Leptin may be a pivotal player in this scenario, as an adipokine which centrally regulates appetite and energy balance. In obesity, excessive caloric intake promotes a low-grade inflammatory response, which leads to dysregulations in lipid storage and adipokine secretion. In turn, these entail alterations in leptin sensitivity, leptin transport across the blood-brain barrier and defects in post-receptor signaling. Furthermore, hypothalamic inflammation and endoplasmic reticulum stress may increase the expression of molecules which may disrupt leptin signaling. Abundant evidence has linked obesity and leptin resistance, which may precede or occur simultaneously to IR and DM2. Thus, leptin sensitivity may be a potential early therapeutic target that demands further preclinical and clinical research. Modulators of insulin sensitivity have been tested in animal models and small clinical trials with promising results, especially in combination with agents such as amylin and GLP-1 analogs, in particular, due to their central activity in the hypothalamus.

Abstract
Oestrus and ovulation synchronisation (E/OS) regimens containing equine chorionic gonadotrophin (ECG) are used for follicular stimulation during the early transitional reproductive phase and goat anestrus. However, the effects of ECG when applied at different times are unknown. Thus, the objective was to evaluate the influence of ECG, breeding procedure, and gonadotrophin-releasing hormone (GnRH) on pregnancy, embryonic viability, and kidding rate in dairy goats. We used 41 alpine goats (mean±standard deviation: 3.82±1.2 years old; 57.0±6.0kg of bodyweight; 1.75-2.25 body condition score; 195±16.7 days in milk; range of 1-4 kiddings). This study took place during the transitional phase (12h of daylight, 12h of dark) in September (35.9° N, 97.3° W) using controlled internal drug release intravaginal inserts (300mg of progestagen; P4) for 11, 12, or 13 days with a 2-mL intramuscular dose containing 10mg of dinoprost tromethamine at P4 removal. The E/OS protocols differed on the time when the 1-mL intramuscular dose of P.G. 600© (Merck Animal Health; 120 and 60IU of ECG and human chorionic gonadotrophin, respectively) was given (i.e. early=24h before P4 removal; late=24h after P4 removal), and the traditional control group did not receive P.G. 600. Time breeding, either by laparoscopic-aided insemination using frozen-thawed semen (n=28) or natural (n=13), was scheduled 48h after P4 removal. To improve embryo survival, 5 days post-breeding (dpb) 21 goats received 1mL of GnRH analogue intramuscularly as 50µgmL−1 gonadorelin diacetate tetrahydrate, and 20 control goats received 1mL of placebo intramuscularly. Pregnancy rate (PR) was evaluated at d 18-24 by non-return to oestrus, d 30 by pregnancy-specific protein B, and d 40 by ultrasound. Kidding rate was determined for females with at least one newborn. Logistic regression was used to establish statistical significance. Days of P4 exposure did not influence any response variable (P>0.20). Table 1 summarises the results; age influenced all PR evaluations. The number of kiddings and administration of GnRH at 5 dpb had a significant effect on PR, whereas bodyweight, days in milk, E/OS protocol, and breeding procedure were not influential. Embryo viability and kidding rate were not influenced by any variable. In short, P.G. 600 had no bearing on any response variable analysed. Late-lactating goats can be evaluated early in the transitional breeding phase using PR at 18-24, 30, or 40 dpb. As indicated by the lack of effect on embryo viability at 30 and 40 days, the mechanism by which GnRH increases PR was not by decreasing embryo mortality.

Abstract
Regulatory T cells (Tregs ) modulate the magnitude of immune responses and possess therapeutic potential in an array of immune diseases. Statins reduce the activation and proliferation of conventional T cells (Tcons ), and they seem to up-regulate the frequency and function of Tregs . However, there is a lack of simultaneous evaluation of the in-vitro effect of statins on the functional profile of Tregs versus Tcons . Herein, magnetically purified Tcons and Tregs were stimulated with CD3/CD28/interleukin (IL)-2 in the presence of atorvastatin (ATV) at 1 or 10 µM. The suppressive function of Tregs , the expression of markers associated with Treg function, activation levels, cytokine production and calcium flux in both subpopulations were assessed by flow cytometry. ATV had no cytotoxic effect on T cells at the concentrations used. Interestingly, 10 µM ATV hampered the suppressive capacity of Tregs . Moreover, this higher concentration reduced the expression of forkhead box protein 3 (FoxP3), cytotoxic T lymphocyte antigen (CTLA-4) and programmed death 1 (PD-1). In Tcons , ATV at 10 µM decreased PD-1 and CD45RO expression. The expression of CD25, CD69, CD95, CD38, CD62L, CCR7 and perforin was not affected in both subpopulations or at any ATV concentrations. Remarkably, 10 µM ATV increased the percentage of tumour necrosis factor (TNF)-α-producing Tregs . Although there was a reduction of calcium flux in Tcons and Tregs , it was only significant in 10 µM ATV-treated Tcons . These results suggested that 10 µM ATV affects the cellular functions of both populations; however, this concentration particularly affected several aspects of Treg biology: its suppressive function, cytokine production and expression of Treg -specific markers.

Abstract
From centuries ago cannabis has been known as a botanic product with several properties, with medical use in the ancient world. Nowadays, it is recognized as the active component of marijuana, the drug with the highest rates of illicit use and abuse worldwide according to data provided by the World Health Organization. A huge debate has emerged in these past years with the growing interest to employ cannabis-based products with therapeutic purposes, a strategy that has increased in various European countries, Canada and more than half of the states that conform the United States, simultaneously with an important increase of flexibility in laws and regulations regarding the recreational use of this substance, especially in North America. Although valid arguments can exist for each side, the potential therapeutic use of substances that have ethical-legal implications such as the case of cannabis, require the prescribing doctor to be knowledgeable and to always be updated on the subject, a robust doctor-patient relationship and educational campaigns with truthful information that allow for full awareness of risks vs benefits.

Abstract
INTRODUCTION Subclinical hypothyroidism (ScH) is an endocrine alteration that is related to cardiovascular risk factors, including those categorized as components of the Metabolic Syndrome (MS). However, findings in prior reports regarding an association between these alterations are inconsistent. The purpose of this study was to determine the relationship between both entities in adult subjects from Maracaibo City, Venezuela. MATERIALS AND METHODS The Maracaibo City Metabolic Syndrome Prevalence Study is a descriptive, cross-sectional study with random and multistage sampling. In this substudy, 391 individuals of both genders were selected and TSH, free T3, and free T4 tests were performed as well as a complete lipid profile, fasting glycaemia, and insulin blood values. ScH was defined according to the National Health and Nutrition Examination Survey (NHANES) criteria: high TSH (≥4.12mUI/L) and normal free T4 (0.9-1,9 ng/dL) in subjects without personal history of thyroid disease. MS components were defined according to IDF/AHA/NHLBI/WHF/IAS/IASO-2009 criteria. A multiple logistic regression analysis was used to assess the relationship between MS components and ScH diagnosis. RESULTS Of the evaluated population, 10.5% (n=41) was diagnosed with ScH, with a higher prevalence in women (female: 13.6% versus male: 7.7%; χ2=3.56, p=0.05). Likewise, 56.1% (n=23) of the subjects with ScH were diagnosed with MS (χ2=4.85; p=0.03), being hyperglycemia the main associated criterion (χ2=11.7; p=0.001). In multivariable analysis, it was observed that the relationship was exclusive with the presence of type 2 diabetes mellitus (T2DM) OR: 3.22 (1.14-9.14); p=0.03. CONCLUSION The relationship between ScH and MS in our population is dependent on the presence of hyperglycemia, specifically T2DM diagnosis, findings that vary from those previously reported in Latin American subjects.

Abstract
INTRODUCTION The evaluation and treatment of pain in hospitalized is still an important health pro blem. OBJECTIVE To know the prevalence, characteristics and approaches to pain management in children and adolescents hospitalized in the Pediatric Hospital of the Pereira Rossell Center (HP-CH- PR), a pediatric reference center in Uruguay. PATIENTS AND METHOD Cross-sectional study, through survey and review of clinical records on 09/13/16. All hospitalized children under the age of 19 were included. VARIABLES age, gender, reason for admission, presence of cognitive disorder, the prevalen ce of pain at some time during hospitalization, in the last 24 hours and during the interview, cause of maximum pain, intensity, pharmacological and non-pharmacological treatment. RESULTS 97.4% (152/156) hospitalized children were included. Pain prevalence at some point during hospitalization: 51.3% (78/152, 95% CI: 43.2-59.3); in the previous 24 hours: 39.5% (60/152, 95% CI: 31.7-47.2); during the interview: 15.8% (24/152, 95% CI: 10-21.5). Intensity: mild 13/24, moderate-severe 11/24. Maximum pain referred during hospitalization: needle punctures 48.5% (38/78). They had some analgesic prescription 47.3% of them had some analgesic prescription. Inadequate interdose inter val: 45.8%; adequate dose 98.9%; intravenous administration: 43.7%; contraindication to oral route: 40.5%. CONCLUSIONS Regarding children and adolescents hospitalized, 39.5% reported pain 24 hours before being the interviewed and 15.8% reported pain during the interview. The maximum pain reported during hospitalization was due to needle punctures. Children in pain with inappropriate analgesic prescriptions are still detected.

Abstract
Background Wide international variation in the prevalence of disabling low back pain (LBP) among working populations is not explained by known risk factors. It would be useful to know whether the drivers of this variation are specific to the spine or factors that predispose to musculoskeletal pain more generally. Methods Baseline information about musculoskeletal pain and risk factors was elicited from 11 710 participants aged 20–59 years, who were sampled from 45 occupational groups in 18 countries. Wider propensity to pain was characterized by the number of anatomical sites outside the low back that had been painful in the 12 months before baseline (‘pain propensity index’). After a mean interval of 14 months, 9055 participants (77.3%) provided follow‐up data on disabling LBP in the past month. Baseline risk factors for disabling LBP at follow‐up were assessed by random intercept Poisson regression. Results After allowance for other known and suspected risk factors, pain propensity showed the strongest association with disabling LBP (prevalence rate ratios up to 2.6, 95% CI: 2.2–3.1; population attributable fraction 39.8%). Across the 45 occupational groups, the prevalence of disabling LBP varied sevenfold (much more than within‐country differences between nurses and office workers), and correlated with mean pain propensity index (r = 0.58). Conclusions Within our study, major international variation in the prevalence of disabling LBP appeared to be driven largely by factors predisposing to musculoskeletal pain at multiple anatomical sites rather than by risk factors specific to the spine. Significance Our findings indicate that differences in general propensity to musculoskeletal pain are a major driver of large international variation in the prevalence of disabling low back pain among people of working age.

Abstract
The CEA family consists of two structurally and functionally distinct subgroups; the group including CEA, NCA and CGM-6 which are cell surface-bound by phosphatidylinositol (PI) linkages, and the group of BGP splice variants which have transmembrane and cytoplasmic domains. Although all CEA family members mediate intercellular adhesion in vitro, the PI-linked group show Ca++ and temperature independent adhesion whereas the BGP group show rapidly reversible Ca++ and temperature dependent adhesion. From the close alignment in cDNA nucleotide sequences between family members and between repeated domains in one family member, it is apparent that the CEA family is now rapidly evolving; in fact, analogs of only the transmembrane BGP group have been found so far in the mouse. The addition of a new group of potent adhesion molecules to complex species at some time after the rodent radiation has strong evolutional implications, which are discussed.

Abstract
BACKGROUND Cellular and molecular mechanisms of acute and chronic lung allograft rejection have yet to be clearly defined, and obliterative bronchiolitis (OB) remains the primary limitation to survival in lung transplant recipients (LTRs). We have previously shown that T-bet-deficient recipients of full major histocompatibility complex (MHC)-mismatched, orthotopic left lung transplants develop accelerated obliterative airway disease (OAD) in the setting of acute cellular rejection characterized by robust alloimmune CD8+ interleukin (IL)-17 and interferon (IFN)-γ responses that are attenuated with neutralization of IL-17. Azithromycin has been shown to be beneficial in some LTRs with bronchiolitis obliterans syndrome/OB. Here, we evaluated the effects of azithromycin on rejection pathology and T-cell effector responses in T-bet-/- recipients of lung transplants. METHODS Orthotopic left lung transplantation was performed in BALB/c → B6 wild type or BALB/c → B6 T-bet-/- strain combinations as previously described. Mice treated with azithromycin received 10 mg/kg or 50 mg/kg subcutaneously daily. Lung allograft histopathology was analyzed at day 10 or day 21 post-transplantation, and neutrophil staining for quantification was performed using anti-myeloperoxidase. Allograft mononuclear cells were isolated at day 10 for T-cell effector cytokine response assessment using flow cytometry. RESULTS We show that while azithromycin significantly decreases lung allograft neutrophilia and CXCL1 levels and attenuates allospecific CD8+ IL-17 responses early post-transplantation, OAD persists in T-bet-deficient mice. CONCLUSIONS Our results indicate that lung allograft neutrophilia is not essential for the development of OAD in this model and suggest allospecific T-cell responses that remain despite marked attenuation of CD8+ IL-17 are sufficient for obliterative airway inflammation and fibrosis.

Abstract
The Southern Westerly Winds (SWW) are the surface expression of geostrophic winds that encircle the southern mid-latitudes. In conjunction with the Southern Ocean, they establish a coupled system that not only controls climate in the southern third of the world, but is also closely connected to the position of the Intertropical Convergence Zone and CO2 degassing from the deep ocean. Paradoxically, little is known about their behavior since the last ice age and relationships with mid-latitude glacier history and tropical climate variability. Here we present a lake sediment record from Chilean Patagonia (51°S) that reveals fluctuations of the low-level SWW at mid-latitudes, including strong westerlies during the Antarctic Cold Reversal, anomalously low intensity during the early Holocene, which was unfavorable for glacier growth, and strong SWW since ~7.5 ka. We detect nine positive Southern Annular Mode-like events at centennial timescale since ~5.8 ka that alternate with cold/wet intervals favorable for glacier expansions (Neoglaciations) in southern Patagonia. The correspondence of key features of mid-latitude atmospheric circulation with shifts in tropical climate since ~10 ka suggests that coherent climatic shifts in these regions have driven climate change in vast sectors of the Southern Hemisphere at centennial and millennial timescales.

Abstract
To determine the predictive power of various anthropometric indices for the identification of dysglycemic states in Maracaibo, Venezuela. A cross-sectional study with randomized, multi-staged sampling was realized in 2230 adult subjects of both genders who had their body mass index (BMI), waist circumference (WC) and waist-height ratio (WHR) determined. Diagnoses of type 2 diabetes mellitus (DM2) and impaired fasting glucose (IFG) were made following ADA 2015 criteria. ROC curves were used to evaluate the predictive power of each anthropometric parameter. Area under the curve (AUC) values were compared through Delong's test. Of the total 2230 individuals (52.6 % females), 8.4 % were found to have DM2, and 19.5 % had IFG. Anthropometric parameters displayed greater predictive power regarding newly diagnosed diabetics, where WHR was the most important predictor in both females (AUC = 0.808; CI 95 % 0.715-0.900. Sensitivity: 82.8 %; specificity: 76.2 %) and males (AUC = 0.809; CI 95 % 0.736-0.882. Sensitivity: 78.6 %; specificity: 68.1 %), although all three parameters appeared to have comparable predictive power in this subset. In previously diagnosed diabetic subjects, WHR was superior to both WC and BMI in females, and WHR and WC were both superior to BMI in males. Lower predictive values were found for IFG in both genders. Accumulation of various altered anthropometric measurements was associated with increased odds ratios for both newly and previously diagnosed DM2. The predictive power of anthropometric measurements was greater for DM2 than IFG. We suggest assessment of as many available parameters as possible in the clinical setting.

Abstract
PURPOSE OF REVIEW Describing the diverse molecular mechanisms (particularly immunological) involved in the death of the pancreatic beta cell in type 1 and type 2 diabetes mellitus. RECENT FINDINGS Beta cell death is the final event in a series of mechanisms that, up to date, have not been entirely clarified; it represents the pathophysiological mechanism in the natural history of diabetes mellitus. These mechanisms are not limited to an apoptotic process only, which is characteristic of the immune-mediated insulitis in type 1 diabetes mellitus. They also include the action of proinflammatory cytokines, the production of reactive oxygen species, DNA fragmentation (typical of necroptosis in type 1 diabetic patients), excessive production of islet amyloid polypeptide with the consequent endoplasmic reticulum stress, disruption in autophagy mechanisms, and protein complex formation, such as the inflammasome, capable of increasing oxidative stress produced by mitochondrial damage. SUMMARY Necroptosis, autophagy, and pyroptosis are molecular mechanisms that modulate the survival of the pancreatic beta cell, demonstrating the importance of the immune system in glucolipotoxicity processes and the potential role for immunometabolism as another component of what once known as the "ominous octet."

However, there is controversy regarding magnesium-related neonatal adverse outcomes, largely driven by a limited understanding of the factors that influence neonatal serum magnesium concentrations and associated outcomes. The objective of this study was to examine the relationship between antenatal maternal magnesium dose and serum concentrations, neonatal serum magnesium concentration and immediate neonatal outcomes. STUDY DESIGN A retrospective study was conducted at a community-based teaching hospital. Neonatal serum magnesium concentrations within 48 h of birth were used to stratify magnesium-exposed neonates into three groups: group 1: <2.5 mg dl-1, group 2: ⩾2.5 to <4.5 mg dl-1, and group 3:⩾4.5 mg dl-1. Immediate neonatal outcomes were compared between the three groups. Total maternal magnesium dose and serum magnesium concentrations before the delivery were correlated with neonatal serum magnesium concentrations and outcomes. RESULTS Of the 304 mother-baby dyads between 24 and 34 weeks gestation, 237 received antenatal magnesium. Neonatal serum magnesium concentration was 3.14±0.83 mg dl-1 in exposed and 1.96±0.42 mg dl-1 in unexposed neonates (P<0.001). Compared with group 2, neonates had higher odds of grade 3 or 4 intraventricular hemorrhage in group 1 (adjusted odds ratio (AOR) 5.95 (95% confidence interval (CI) 1.05 to 33.66)) and group 3 (AOR 8.42 (95% CI 1.35 to 52.54)). Group 3 neonates also had increased odds of periventricular leukomalacia (AOR: 5.37 (95% CI 1.02 to 28.28) compared with group 2 neonates. Predictors of neonatal serum magnesium concentrations included maternal magnesium dose (r=0.66, P<0.0001), duration of therapy (r=0.70, P<0.0001) and serum concentration (r=0.72, P<0.001). CONCLUSION The between-group differences highlight that there is a therapeutic range of neonatal serum magnesium concentrations for neuroprotective effects of antenatal magnesium sulfate, while concentrations outside of this range may be associated with adverse neonatal outcomes. Further studies are needed to determine the optimal dose and duration of maternal magnesium to minimize adverse neonatal outcomes.

Abstract
The release of DNA into the extracellular milieu by neutrophil during a process called NETosis has been postulated as an additional source of autoantigens; a process believed to be important in the pathogenesis of some autoimmune disease, such as systemic lupus erythematosus (SLE). However, it is not established if the B and T cells undergo the release of DNA to the extracellular milleu, in response to different stimuli. In this study, it was observed that the treatment of B and T cells with PMA, ionomycin and the serum from patients with SLE induced the extracellular DNA presence in B and T cells. These findings suggest that the phenomenon were similar to those observed in neutrophil's Etosis; B and T cells also released their DNA into the extracellular milieu. The findings express that serum from patients with SLE and SLEDAI ≤ 8 triggers the release of extracellular DNA in neutrophils, B and T cells, that suggested the presence of soluble factors in the serum that favoured this phenomenon.

Abstract
Few studies have reported on sexually transmitted infections at the US–Mexico border, so the prevalence of Chlamydia trachomatis in this population remains uncertain. This binational project investigated the prevalence of, and risk factors for, C. trachomatis among women along the Arizona, US–Sonora, Mexico border. Women who self-referred for routine gynaecological care were invited to complete an interviewer-administered questionnaire and to undergo a Pap smear, C. trachomatis test, and HPV test. In 2270 women, C. trachomatis prevalence overall was 8.2% as measured by hybrid capture and 2.6% by enzyme immunoassay. Infection was associated with young age, a history of new sexual partner(s) in the previous three months, HPV infection, and proximity of clinic to the international border. Antibiotic use in the previous 30 days was associated with decreased odds of infection. Women in Arizona–Sonora border communities are at increased risk for C. trachomatis infection compared to women attending clinics in non-border locations.

Abstract
Stool samples were obtained from healthy children and children with diarrhoea in Rio de Janeiro, Brazil, and analysed for aichivirus A and salivirus by reverse transcription PCR. Aichivirus A was detected in 5 (0.8%) and salivirus in 10 (1.7%) of the samples obtained from children with diarrhoea. None of the healthy children tested positive for these viruses. The results demonstrate that these viruses continuously circulate in the country, although at a low frequency.

Abstract
Histological observations showed the presence of a Perkinsus sp. parasite in Cerastoderma edule tissues for the first time in the Spanish Mediterranean coast. ITS molecular characterization by PCR-RFLP, in situ hybridization and sequencing, identified the parasite as Perkinsus chesapeaki, with a maximum identity of 99-100% with GenBank P. chesapeaki sequences from France and 97% with P. chesapeaki sequences of North American origin when BLAST analysis was carried out. Furthermore, phylogenetic studies placed the European cockle parasite in a well defined cluster together with the other European isolates. This is the first report of P. chesapeaki in the cockle C. edule.
