Low muscle mass index is associated with type 2 diabetes risk in a Latin-American population: a cross-sectional study.

Objective: Diabetes mellitus is a growing disease with severe complications. Various scores predict the risk of developing this pathology. The amount of muscle mass is associated with insulin resistance, yet there is no established evidence linking muscle mass with diabetes risk. This work aims to study that relationship. Research methods and procedures: This cross-sectional study included 1,388 employees. The FINDRISC score was used to assess type 2 diabetes risk, and bioimpedance was used for body composition analysis. Appendicular skeletal muscle mass adjusted by body mass index (ASM/BMI) was analyzed. Sociodemographic, clinical and anthropometric measures were evaluated, logistic regression models with sex stratification were conducted and ROC curves were calculated to determine the ability of ASM/BMI index to predict T2D risk. Results: It was observed that patients with higher ASM/BMI had a lower FINDRISC score in both men and women (p < 0.001). A logistic regression model showed and association between ASM/BMI and diabetes risk in women [OR: 0.000 (0.000-0.900), p = 0.048], but not in men [OR: 0.267 (0.038-1.878), p = 0.185]. However, when the body mass index variable was excluded from the model, an association was found between muscle mass adjusted to BMI and diabetes risk in both men [OR: 0.000 (0.000-0.016), p < 0.001], and women [OR:0.001 (0.000-0.034), p < 0.001]. Other risk factors were having a low level of physical activity, waist circumference, age and sedentary lifestyle. A ROC curve was built and the optimal ASM/BMI cut-of value for predicting T2D risk was 0.82 with a sensitivity of 53.71% and specificity of 69.3% [AUC of 0.665 (0.64-0.69; p < 0.0001)]. Conclusion: When quantifying the risk of type 2 diabetes in both women and men, assessing muscle mass can help detect adult individuals with a high risk of developing type 2 diabetes.

Vaginal Microbiota and Proinflammatory Status in Patients with Polycystic Ovary Syndrome: An Exploratory Study.

Background/Purpose: Polycystic ovary syndrome (PCOS) is an endocrine-metabolic disease most common in patients of childbearing age. This pathology is associated with clinical, metabolic, and reproductive complications. We evaluated the diversity of the vaginal microbiota (VM), the vaginal inflammatory reaction (VIR), the proinflammatory state, and the activation of polymorphonuclear neutrophils (PMN) with the production of neutrophil extracellular traps (NETs). Methods: Thirty-three patients who attended a consultation at the Hospital UTPL-Santa Inés, Loja, Ecuador, from May to August 2023 who were diagnosed with PCOS participated in this study. Blood samples, vaginal discharge, and a survey were obtained. Results: A high number of patients, 23/33 (69.7%), presented altered microbiota in clinical variables associated with PCOS phenotypes A and B, sexual partners (>2), and oligomenorrhoea. A significant statistical association was only observed for sexually transmitted infections at sampling (p = 0.023) and insulin (p = 0.002). All eight cases studied with VIR had PMN/NETotic activity. A high frequency of proinflammatory states was observed in all vaginal microbiota states. Conclusions: These results suggest that the PCOS could trigger a proinflammatory state in the vaginal epithelium independently of the state of the vaginal microbiota. Furthermore, the presence of NETs observed in the cases studied could decrease fertility in these PCOS patients.

Phenotypic Characterization of Patients with Polycystic Ovary Syndrome in a Population from the Ecuadorian Andes: A Cross-Sectional Study.

Background: Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine-metabolic disorder in women of reproductive age. Diagnosis is based on the evidence-based international guideline 2018 and the Rotterdam Consensus to classify PCOS phenotypes. This study aims to characterize the biodemographic, clinical, metabolic, and reproductive variables and their relationship with PCOS phenotypes in a population from the Ecuadorian Andes. Methodology: A cross-sectional study was conducted with a non-random consecutive sample of 92 women who attended the outpatient gynecology and endocrinology clinic at the Hospital of the Technical University of Loja (UTPL)-Santa Inés, Loja, Ecuador, between January 2022 and July 2023. Descriptive statistics, mean calculations, standard deviation, parametric and nonparametric tests, odds ratios (OR), confidence intervals (CI), and p-values were employed. Results: The average age was 22 ± 3.4 years, with a predominantly mestizo, urban, single, highly educated, and medium-high socioeconomic level population. It was identified that phenotypes A + B are at a higher risk of developing oligomenorrhea and hypertriglyceridemia compared to phenotypes C + D, with statistically significant differences (p < 0.05). Furthermore, in terms of reproductive variables, phenotypes A + B exhibit a significantly higher frequency of elevated anti-Müllerian hormone (AMH) compared to phenotypes C + D, also with statistical significance (p < 0.05). Conclusions: The classical phenotypes A and B of PCOS are the most common in Ecuadorian Andean women and carry a higher risk of insulin resistance, anovulation, metabolic disorders, and elevated triglyceride levels compared to phenotypes C and D. Ethnic diversity and sociocultural habits influence the prevalence and clinical manifestations of these phenotypes.

Improving the Management of Children with Fevers by Healers in Native Rural Areas in the South of Ecuador.

BACKGROUND: Indigenous populations are represented among the poor and disadvantaged in rural areas. High rates of infectious diseases are observed in indigenous child populations, and fever as a general symptom is common. OBJECTIVE: We aim to improve the skills of healers in rural indigenous areas in the South of Ecuador for managing children with fevers. METHOD: We performed participatory action research (PAR) for this study with 65 healers. RESULTS: The PAR focused on the following four phases: (1) 'observation,' eight focus groups were used. (2) 'planning' phase was developed, and with culturally reflective peer group sessions, a culturally adapted flowchart was constructed titled "Management of children with fever." In phase (3): 'action', the healers were trained to manage children with fever. Phase (4): 'evaluation', 50% of the healers used the flowchart. CONCLUSIONS: Explicit recognition of the need for traditional healers and health professionals in indigenous communities to work together to improve health indicators such as infant mortality exists. Additionally, strengthening the transfer system in rural areas is based on knowledge and cooperation between the community and the biomedical system.

Epigenetics in Obesity and Diabetes Mellitus: New Insights.

A long-term complication of obesity is the development of type 2 diabetes (T2D). Patients with T2D have been described as having epigenetic modifications. Epigenetics is the post-transcriptional modification of DNA or associated factors containing genetic information. These environmentally-influenced modifications, maintained during cell division, cause stable changes in gene expression. Epigenetic modifications of T2D are DNA methylation, acetylation, ubiquitylation, SUMOylation, and phosphorylation at the lysine residue at the amino terminus of histones, affecting DNA, histones, and non-coding RNA. DNA methylation has been shown in pancreatic islets, adipose tissue, skeletal muscle, and the liver. Furthermore, epigenetic changes have been observed in chronic complications of T2D, such as diabetic nephropathy, diabetic retinopathy, and diabetic neuropathy. Recently, a new drug has been developed which acts on bromodomains and extraterminal (BET) domain proteins, which operate like epigenetic readers and communicate with chromatin to make DNA accessible for transcription by inhibiting them. This drug (apabetalone) is being studied to prevent major adverse cardiovascular events in people with T2D, low HDL cholesterol, chronic kidney failure, and recent coronary events. This review aims to describe the relationship between obesity, long-term complications such as T2D, and epigenetic modifications and their possible treatments.

Culturally adapted flowcharts in obstetric emergencies: a participatory action research study.

INTRODUCTION: Maternal mortality is a health problem in developing countries and is the result of several factors such as sociodemographic and economic inequalities and difficulties in accessing the health services. In addition, training strategies in obstetric emergencies targeting the non-medical personnel such as traditional midwives are scarce. The focus of this study is to develop learning and communication bridges on the management of obstetric emergencies and on policies of patients' referral to the biomedical health system in rural areas. METHODOLOGY: A Participant Action Research (PAR) study with a mixed methods approach was set up to elaborate culturally adapted flowcharts. The project lasted approximately 3,5 years, from September 2016 to January 2021. RESULTS: The study was conducted with 94 traditional midwives from southern Ecuador and is divided into 4 phases, namely: 1) Exploration: focus groups and interviews were conducted to document the management of obstetric emergencies through the presentation of "clinical case" scenarios in three important topics, namely: pre-eclampsia, shoulder dystocia and postpartum hemorrhage, 2) Planning: a number of reflective sessions were conducted between the researchers and the healers/midwives to elaborate flowcharts. 3) Action: the training was conducted in rooms dedicated to proficiency in the aforementioned topics and using the flowcharts, 4) Evaluation: 90% of the participants reported having used the flowcharts during the first year after the training. The most frequently used flowchart was that of pre-eclampsia for the recognition of warning signs during pregnancy control. CONCLUSION: This study documents common practices of pregnancy and delivery management by traditional midwives. Furthermore, cultural flowcharts were developed for and together with midwives to improve the clinical response to obstetric emergencies. The preliminary evaluation was favorable; the most frequently used flowchart concerned preeclampsia. In this process, establishing a partnership was crucial for successful intercultural collaboration.

Knowledge and Perceptions about Cervical Cancer and HPV Screening in Women in Rural Areas of Ecuador: A Qualitative Research Study.

BACKGROUND: Cervical cancer continues to be a major health problem in developing countries. Educational programs, as well as Pap and HPV screening and vaccination, are important tools to reduce the morbidity and mortality rates associated with this disease. The objective of this study is to explore the diverse knowledge and perceptions about cervical cancer and the different diagnostic tests for HPV of populations living in the rural parish "El Valle". METHOD: A qualitative study was conducted through eight focus groups, which included 46 participants from mixed ethnic groups. A phenomenological analysis was performed. RESULTS: Four topics and seven sub-topics were identified. By analyzing all the narratives, it was possible to identify that the perception of cervical cancer was focused on its severity, secondary to its infectious process and screening periodicity. However, despite the diverse knowledge, indigenous people do not relate it to the human papilloma virus; in addition, there is also certain resistance to undergo the Pap smear test, for reasons such as inaccessibility and its sampling process. CONCLUSIONS: It is necessary to develop educational programs for the prevention of cervical cancer and to implement diagnostic alternatives to reach populations with precarious accessibility, as well as women who refuse to undergo the Pap smear test.

Perceptions of Ecuadorian indigenous healers on their relationship with the formal health care system: barriers and opportunities.

BACKGROUND: The new paradigm of intercultural policies focuses on rethinking the common public culture. In Ecuador, the "Buen Vivir" plan seeks to incorporate the ancestral medical knowledge, experience and beliefs of traditional healers into the formal health services. This study explores views on the formal health system from the perspective of the healers belonging to the Kichwa and Shuar ethnicities in the South of Ecuador. METHODS: A qualitative study with a phenomenological approach was performed. Focus groups were conducted in three locations in Southern Ecuador. Shuar, Kichwa and Mestizo ethnic groups were included in the research. RESULTS: Eleven focus groups with a total of 110 participants belonging to the Shuar, Kichwa and Mestizo ethnic groups participated in the study. Six themes were created through analysis: 1) conflicts with health professionals, 2) acceptance of traditional healers, 3) respect, 4) work as a team, 5) environment and patient care, and 6) salary and recognition. CONCLUSION: This study indicated the perceived barriers compromising respectful collaboration between health staff and traditional healers from an indigenous perspective. Power inequalities and a historically unidirectional relationship and, in addition, differences in health beliefs, seem to create misunderstandings regarding each other's approach when faced with health and disease. However, insight in these barriers can create opportunities towards collaboration, which will have a positive effect on patient confidence in one or both systems and support continuity between traditional healers and the formal health system.

Towards an indigenous definition of health: an explorative study to understand the indigenous Ecuadorian people's health and illness concepts.

BACKGROUNDS: An intercultural society facilitates equitable and respectful interrelations. Knowing and understanding each other's sociocultural and linguitic contexts is a prerequisite for an intercultural society. This study explores the concepts of health and illness among healers of indigenous ethnicities in Southern Ecuador. METHODS: A qualitative observational study with eleven focus groups was conducted in three locations in Southern Ecuador; a total of 110 participants the Shuar, Kichwa and Mestizo ethnic groups were included. A phenomenological and hermeneutic analysis was conducted. RESULTS: Fourteen main subtopics around of two predefined themes, i.e., "Health" and "Illness" were identified: 1) four bodies, 2) religiosity, 3) health as a good diet, 4) health as god's blessing or a gift, 5) health as balance/ harmony, 6) health as community and social welfare, 7) health as potentiality or a skill, 8) health as peacefulness, 9) heath as individual will, 10) illness as an imbalance, 11) illness as bad energy, 12) illness as a bad diet, 13) illness as suffering or worry, and 14) illness from God, Nature and People illness. By analysing all the topics' and subtopics' narratives, a health and illness definition was developed. The principal evidence for this new framework is the presence of interculturality as a horizontal axis in health. The indigenous perspective of health and illness focus on a balance between 4 bodies: the physical, spiritual, social and mental bodies. Additionally, "good health" is obtained through of the good diet and balanced/harmony. CONCLUSION: Indigenous healers in Southern Ecuador have views on health and illness that differ from the Western biomedical model of care. These different views must be recognized and valued in order to build an intercultural (health) system that empowers both ancestral and modern medical knowledge and healing.

Cluster Analysis of Obesity Disease Based on Comorbidities Extracted from Clinical Notes.

Clinical notes provide a comprehensive and overall impression of the patient's health. However, the automatic extraction of information within these notes is challenging due to their narrative style. In this context, our goal was to identify clusters of patients based on fourteen comorbidities related to obesity, automatically extracted with the cTAKES tool from the i2b2 Obesity Challenge data. Furthermore, results were compared with clusters obtained from experts' annotated data. The sparse K-means algorithms were used in both experiment at two levels: at the first level, three clusters were found, and at the second, new clusters were found by applying the same algorithm to each of the clusters from the former level. The results show that three types of clusters could be identified based on the number of comorbidities and the percentage of patients suffering from them. Diabetes, hypercholesterolemia, atherosclerotic cardiovascular diseases, congestive heart failure, obstructive sleep apnea, and depression were the diseases with the highest weights contributing to the cluster distribution.
