Diabetic Ketoacidosis in Type 1 Diabetes Onset in Latin American Children.

OBJECTIVE: To describe the patterns of diabetic ketoacidosis (DKA) occurrence in children newly diagnosed with type 1 diabetes (T1DM) across several Latin American pediatric diabetes centers from 2018 to 2022. METHODS: A retrospective chart review included children under 18 with new-onset T1DM from 30 Latin American pediatric diabetes centers (Argentina, Chile, and Peru) between 30 December 2018 and 30 December 2022. Multiple logistic regression models examined the relationships between age, gender, medical insurance, BMI, and DKA at new-onset T1DM. As far as we know, there are no large studies in Latin American countries exploring the patterns of DKA in new-onset T1DM. RESULTS: A total of 2,026 (983 females) children, median age 9.12 (5.8 -11.7) years with new-onset-T1DM were included. Approximately 50% had no medical insurance. Mean glucose values were 467 mg/dL, pH 7.21, bicarbonate 13 mEq/L, HbA1c 11.3%, and BMI 18. The frequency of DKA was 1,229 (60.7%), out of which only 447 (36%) were severe. There was a significant decrease in the frequency of DKA as age increased: 373 (70.2%) in children under 6, 639 (61.6%) in those between 6 and 12, 217 and (47.5%) in those over 12. Children with medical insurance (58.8%) had a significantly lower frequency of DKA than those without (62.7%). The multiple logistic regression models showed that DKA was significantly and inversely associated with age [OR, 0.72 (95% CI 0.60-0.86)], BMI [OR, 0.95 (95% CI 0.92-0.99)], and medical insurance [OR, 0.75 (95% CI 0.60-0.94)] adjusted for sex. CONCLUSION: Latin American children with new-onset T1DM exhibited a substantial occurrence of DKA. Younger ages and the lack of medical insurance were significantly associated with DKA in new-onset T1DM.

Sustainability of an Opt-Out Electronic-Health Record-based Tobacco Treatment Consult Service at a large safety-net hospital: A 6-year Analysis.

INTRODUCTION: Our safety-net hospital implemented a hospital-based tobacco treatment intervention in 2016. We previously showed the intervention, an "opt-out" Electronic Health Record (EHR)-based Best Practice Alert (BPA)+order-set that triggers consultation to an inpatient Tobacco Treatment Consult (TTC) service for all patients who smoke, improves smoking abstinence. We now report on sustainability, 6 years after inception. METHODS: We analyzed data collected between July 2016-June 2022 of patients documented as 'currently smoking' in the EHR. Across the 6 years, we used Pearson's correlation analysis to compare Adoption (clinician acceptance of the BPA+order-set, thus generating consultation to the TTC service); Reach (number of consultations completed by the TTC service); and Effectiveness (receipt of pharmacotherapy orders between patients receiving and not receiving consultations). RESULTS: Among 39,558 adult admissions (July 2016-June 2022) with "currently smoking" status in the EHR for whom the BPA triggered, clinicians accepted the TTC order-set on 50.4% (19,932/39,558), though acceptance varied across services [e.g., Cardiology (71%) and Obstetrics-Gynecology (12%)]. The TTC service consulted on 17% (6779/39,558) of patients due to staffing constraints. Consultations ordered (r=-0.28, p=0.59) and completed (r= 0.45, p=0.37) remained stable over six-years. Compared to patients not receiving consultations, patients receiving consultations were more likely to receive pharmacotherapy orders overall (inpatient: 50.8% vs 35.1%, p<.0001; at discharge: 27.1% vs 10%, p<.0001) and in each year. CONCLUSIONS: The "opt-out" EHR-based TTC service is sustainable, though many did not receive consultations due to resource constraints. Healthcare systems should elevate priority of hospital-based tobacco treatment programs to increase reach to underserved populations. IMPLICATIONS: Our study shows that opt-out approaches that utilize the EHR are a sustainable approach to provide evidence-based tobacco treatment to all hospitalized individuals who smoke, regardless of readiness to stop smoking and clinical condition.

Widespread Resistance to Temephos in Aedes aegypti (Diptera: Culicidae) from Mexico.

Organic synthetic insecticides continue to be part of the arsenal for combating vector-borne diseases in Mexico. Larvicides are a fundamental part of the process in programs for mosquito control, temephos being one of the most widely used in Mexico. In the present study, we analyzed the frequency of temephos resistance in twenty-three Aedes aegypti populations using the discriminating concentration (DC) of 0.012 mg/L. We also tested 5× DC (0.6 mg/L) and 10× DC (0.12 mg/L) of temephos. The resistance distribution to temephos was interpolated to unsampled sites using the inverse distance weighting (IDW) method. The populations of Ae. aegypti showed a high frequency of resistance (1× DC) with mortality rates below 93% in 22 of the 23 populations analyzed. Moderate resistance intensity (5× DC) was found in 78% of the populations, and high intensity (10× DC) in 30%. Predicted mortality was below 60% in the populations of the Pacific Coast, along the Gulf of Mexico, and in the state of Coahuila in Northeastern Mexico in relation to 1× DC; the Pacific Coast and Northeast patterns hold for 5× and 10× DC. The results suggest the need for rotation of the larvicide to effectively control the larval populations of the vector in the country.

Utilización de servicios de salud en México: cascada de atención primaria en 2022.

OBJETIVO: Presentar un panorama descriptivo de las elecciones de la población mexicana frente a una necesidad de salud en 2022. Material y métodos. Se utilizaron datos de la Encuesta Nacional de Salud y Nutrición Continua 2022. RESULTADOS: De 24.6% de la población que informó haber tenido una necesidad de salud en los últimos tres meses, 44% recibió atención en servicios públicos. El uso de servicios privados es extensivo a toda la población, pero fue más elevado en aquellos sin derechohabiencia. Se encontró que 71% de los motivos por los que las personas no se atendieran en el lugar que les correspondía de acuerdo con su derechohabiencia tuvo que ver con el acceso y 21% con la percepción de calidad. Entre los motivos de acceso para elegir el lugar donde se atendieron destacan la afiliación, la cercanía y el costo. En cuanto a la calidad, resaltan la atención rápida y la satisfacción con la atención. CONCLUSIONES: Con el fin de reducir la desigualdad de acceso y el gasto de bolsillo asociado con un mayor uso de servicios privados, sobre todo entre la población sin seguridad social, mejorar el acceso (como la distancia, los horarios de atención, las barreras burocráticas) puede ayudar a avanzar en este objetivo.

Exploring the relationship between baseline health-related quality of life (AQoL-4D utility values) and mortality during long-term follow-up for people living with a psychotic disorder.

Holistic summary measures of health-related quality of life (HRQoL) could provide useful information for screening and/or monitoring high-risk individuals. This study explores the association of baseline HRQoL (AQoL-4D values) with death from natural and external causes (such as suicide, overdose, or accident) in a prevalent cohort over a mean follow-up of 6.9-years. Baseline data were obtained from the 2010 National Survey of High Impact Psychosis (SHIP) and its 2012 sister survey, the North-Metro Survey of High Impact Psychosis. Follow-up data were obtained from the National Deaths Index (to January 18, 2018). Associations between baseline HRQoL (and the 12 individual items of the AQoL-4D) and deaths by cause, stratified by sex were investigated using multivariable Cox Proportional Hazards models, with age used as the time scale. Overall, 7.6 % of the cohort (137 of 1805 people meeting ICD-10 criteria for a psychotic disorder and agreeing to linkage) died, 4.2 % from natural causes (primarily heart disease and cancer) and 3.4 % from external causes. There was an association between low HRQoL (AQoL-4D ≤ 0.20) and mortality due to natural causes, primarily driven by difficulties with mobility and vision in men, and difficulty with household tasks in women. No significant associations were obtained between AQoL-4D utilities and death from external causes. Sleep problems were associated with death from external causes for men only. As people with psychotic disorders experience multiple causes of death with complex associations which are difficult to quantify, monitoring for low HRQoL using the AQoL-4D could be a useful indicator of increased mortality risk in this population. TWITTER: Monitoring for low HRQoL (AQoL-4D ≤ 0.20) could be a useful indicator of increased mortality risk from natural causes in people living with psychotic disorders, with differing but specific items of relevance to men and women.

Genetic or pharmacological GHSR blockade has sexually dimorphic effects in rodents on a high-fat diet.

The stomach-derived hormone ghrelin regulates essential physiological functions. The ghrelin receptor (GHSR) has ligand-independent actions, therefore, GHSR gene deletion may be a reasonable approach to investigate the role of this system in feeding behaviors and diet-induced obesity (DIO). Here we investigated the effects of a long-term (12 month) high-fat (HFD) versus regular diet on obesity-related measures in global GHSR-KO and wild type (WT) Wistar male and female rats. Our main findings were that the GHSR gene deletion protects against DIO and decreases food intake during HFD in male but not in female rats. GHSR gene deletion increased thermogenesis and brain glucose uptake in male rats and modified the effects of HFD on brain glucose metabolism in a sex-specific manner, as assessed with small animal positron emission tomography. RNA-sequencing was also used to show that GHSR-KO rats had upregulated expression of genes responsible for fat oxidation in brown adipose tissue. Central administration of a novel GHSR inverse agonist, PF-5190457, attenuated ghrelin-induced food intake, but only in male, not in female mice. HFD-induced binge-like eating was reduced by inverse agonism in both sexes. Our results support GHSR as a promising target for new pharmacotherapies for obesity.

Health-Related Quality of Life Scores and Values as Predictors of Mortality: A Scoping Review.

Health-related quality of life (HRQoL) can be assessed through measures that can be generic or disease specific, encompass several independent scales, or employ holistic assessment (i.e., the derivation of composite scores). HRQoL measures may identify patients with differential risk profiles. However, the usefulness of generic and holistic HRQoL measures in identifying patients at higher risk of death is unclear. The aim of the present study was to undertake a scoping review of generic, holistic assessments of HRQoL as predictors of mortality in general non-patient populations and clinical sub-populations with specified conditions or risk factors in persons 18 years or older. Five databases were searched from 18 June to 29 June 2020 to identify peer-reviewed published articles. The searches were updated in August 2022. Reference lists of included and cited articles were also searched. Of 2552 articles screened, 110 met criteria for inclusion. Over one-third of studies were from North America. Most studies pertained to sub-populations with specified conditions and/or risk factors, almost a quarter for people with cardiovascular diseases. There were no studies pertaining to people with mental health conditions. Nearly three-quarters of the studies used a RAND Corporation QoL instrument, predominantly the SF-36, and nearly a quarter, a utility instrument, predominantly the EQ-5D. HRQoL was associated with mortality in 67 of 72 univariate analyses (92%) and 100 of 109 multivariate analyses (92%). HRQoL was found to be associated with mortality in the general population and clinical sub-populations with physical health conditions. Whether this relationship holds in people with mental health conditions is not known. HRQoL assessment may be useful for screening and/or monitoring purposes to understand how people perceive their health and well-being and as an indicator of mortality risk, encouraging better-quality and timely patient care to support and maximize what may be a patient's only modifiable outcome.

Evaluation of susceptibility to organophosphates in populations of Aedes aegypti in La Guajira, Colombia / Evaluación de la sensibilidad a organofosforados en poblaciones de Aedes aegypti (L.) (Diptera: Culicidae) del departamento de La Guajira, Colombia

Introduction. Dengue is a public health problem in La Guajira region. Control has focused on the vector using insecticides, including organophosphates. Objective. To evaluate the state of susceptibility to organophosphates insecticides in fifteen Aedes aegypti (L.) populations in La Guajira, Colombia. Materials and methods. We collected samples of third-instar larvae and adult mosquitoes of Ae. aegypti in the municipalities of Albania, Barrancas, Dibulla, Distracción, El Molino, Fonseca, Hatonuevo, La Jagua del Pilar, Maicao, Manaure, Riohacha, San Juan del Cesar, Uribia, Urumita, Villanueva. Bioassays for temefos, malathion, and pirimiphos-methyl were carried out following the methodology of the World Health Organization, and the bottle technique using the guidance of the Centers for Disease Control and Prevention. Susceptibility to temefos was determined through the resistance ratio between lethal concentration 50 and lethal concentration 95; for the compounds temefos, malathion and pirimiphos-methyl, susceptibility was calculated using diagnostic dose and diagnostic time in the populations evaluated. Rockefeller susceptible strain was used as a control. Results: All evaluated populations of Ae. aegypti from La Guajira were found to be susceptible to temefos (ratio resistance to CL50<5.0; ratio resistance to CL95<5.0; 98 - 100 % mortality); pirimiphosmethyl (99 - 100 % mortality), and malathion (100 % mortality). Conclusion. Based on the results, the use of temefos, malathion, and pirimiphosmethyl is feasible for the control of Ae. aegypti in the evaluated populations.

Conclusión. Con base en los resultados obtenidos, es factible el uso de temefos, malatión y metil-pirimifos para el control de Ae. aegypti en las poblaciones evaluadas.

Warning labels on alcoholic beverage containers: a pilot randomized experiment among young adults in Mexico.

BACKGROUND: Little is known about the potential impacts of visible and up-to-date health warning labels on alcoholic beverage containers on a range of outcomes in low- and middle-income countries. We conducted an experimental study to test the potential impacts of visible health warning labels (on the principal panel of the package) on thinking about health risks, product attractiveness, visual avoidance, and intention to change alcohol use among students in Mexico aged 18-30 years. METHODS: A double-blind, parallel-group, online randomized trial was conducted from November 2021 to January 2022 in 11 states in Mexico. In the control group, participants were presented with the image of a conventional beer can with a fictional design and brand. In the intervention groups, the participants observed pictograms with a red font and white backgrounds (health warning label in red-HWL red) or with a black font and yellow backgrounds (health warning label in yellow-HWL yellow), located at the top, covering around one-third of the beer can. We used Poisson regression models -unadjusted and adjusted for covariates- to assess differences in the outcomes across study groups. RESULTS: Using intention-to-treat analysis (n = 610), we found more participants in groups HWL red and HWL yellow thought about the health risks from drinking beer compared to the control group [Prevalence Ratio (PR) = 1.43, CI95%:1.05,1.93 for HWL red; PR = 1.25, CI95%: 0.91, 1.71 for HWL yellow]. A lower percentage of young adults in the interventions vs control group considered the product attractive (PR 0.74, 95%CI 0.51, 1.06 for HWL red; PR 0.56, 95%CI 0.38, 0.83 for HWL yellow). Although not statistically significant, a lower percentage of participants in the intervention groups considered buying or consuming the product than the control group. Results were similar when models were adjusted for covariates. CONCLUSIONS: Visible health warning labels could lead individuals to think about the health risks of alcohol, reducing the attractiveness of the product and decreasing the intention to purchase and consume alcohol. Further studies will be required to determine which pictograms or images and legends are most contextually relevant for the country. TRIAL REGISTRATION: The protocol of this study was retrospectively registered on 03/01/2023: ISRCTN10494244.

Status of Acaricide Resistance and Detecting the Knockdown Resistance Mutation T2134A in the Cattle Tick Rhipicephalus microplus (Acari: Ixodidae) from Northeastern Mexico.

Rhipicephalus microplus is the most important tick in veterinary medicine, given its repercussions on animal production. The principal strategy to avoid adverse effects associated with R. microplus is the chemical control of tick populations through organosynthetic acaricides. Therefore, monitoring susceptibility to acaricides is paramount in any control program. This study aimed to analyze the resistance status of 2 populations of R. microplus from northeastern Mexico to the organochlorine (OC) lindane, organophosphates (OP) coumaphos, chlorfenvinphos, diazinon, and chlorpyrifos, and the synthetic pyrethroids (SPs) flumethrin, deltamethrin, and cypermethrin. Discriminating doses (DD) of each acaricide were used in the larval packet bioassay (LPT). Additionally, the presence of the knockdown resistance (kdr) mutation T2134A associated with pyrethroid resistance was evaluated using allele-specific polymerase chain reaction (PCR). The populations of R. microplus showed a high frequency of resistance to SP, with mortality rates of less than 5%; they also showed resistance to the OPs (diazinon and chlorpyrifos) with mortality rates ranging from 1.29% to 34.62%; meanwhile, they were susceptible to coumaphos and chlorfenvinphos. Mortality rates higher than 66% were observed for lindane, indicating susceptibility. The mutant allele of the kdr mutation T2134A was detected in 75% and 100% of the pools analyzed. The populations studied presented a highly resistant profile to pyrethroids, with the presence of the kdr mutant allele A2134. The susceptibility to the organophosphates such as coumaphos and chlorfenvinphos of R. microplus from northeastern Mexico should be noted.

The underexplored presence of seasonal affective disorder in the southern hemisphere: A narrative review of the Australian literature.

BACKGROUND: Seasonal Affective Disorder (SAD) is well documented in the medical literature, particularly in more northern latitudes in agreement with proposed hypotheses for SAD's pathophysiology. However, in the southern latitudes SAD's presence remains underexplored. The second largest country in the southern hemisphere is Australia. Australia has wide ranging geographical and climatic differences that are expected to support SAD's presence. The aim of this study is therefore, to establish an evidence base for SAD in Australia. METHODS: PubMed and Google Scholar were searched for published peer-review studies focussed on, or related to SAD, winter depression or seasonal variation in mood in Australia. There were no time-period restrictions. RESULTS: Thirteen studies were identified. Studies explored the presence/nature of SAD, contributing factors, autonomic activity, treatment, and the validity of the Seasonal Pattern Assessment Questionnaire in the Australian population. An association between changes in mood and behaviour and seasonal occurrence was clearly identified, with SAD's presence varying by location. The highest percentage of study participants with SAD in a single location was observed in Tasmania, Australia's most southern state. The findings and interpretations of the studies included in this review are subject to the number of locations assessed, the number of studies undertaken at each location and individual study limitations. CONCLUSIONS: Ascertaining information on the prevalence and correlates of SAD in the southern hemisphere, particularly in high-risk locations could contribute to clinical literacy into the syndrome, support management practices, and promote the early identification and treatment of the disorder.

A new WHO bottle bioassay method to assess the susceptibility of mosquito vectors to public health insecticides: results from a WHO-coordinated multi-centre study.

BACKGROUND: The continued spread of insecticide resistance in mosquito vectors of malaria and arboviral diseases may lead to operational failure of insecticide-based interventions if resistance is not monitored and managed efficiently. This study aimed to develop and validate a new WHO glass bottle bioassay method as an alternative to the WHO standard insecticide tube test to monitor mosquito susceptibility to new public health insecticides with particular modes of action, physical properties or both. METHODS: A multi-centre study involving 21 laboratories worldwide generated data on the susceptibility of seven mosquito species (Aedes aegypti, Aedes albopictus, Anopheles gambiae sensu stricto [An. gambiae s.s.], Anopheles funestus, Anopheles stephensi, Anopheles minimus and Anopheles albimanus) to seven public health insecticides in five classes, including pyrethroids (metofluthrin, prallethrin and transfluthrin), neonicotinoids (clothianidin), pyrroles (chlorfenapyr), juvenile hormone mimics (pyriproxyfen) and butenolides (flupyradifurone), in glass bottle assays. The data were analysed using a Bayesian binomial model to determine the concentration-response curves for each insecticide-species combination and to assess the within-bioassay variability in the susceptibility endpoints, namely the concentration that kills 50% and 99% of the test population (LC50 and LC99, respectively) and the concentration that inhibits oviposition of the test population by 50% and 99% (OI50 and OI99), to measure mortality and the sterilizing effect, respectively. RESULTS: Overall, about 200,000 mosquitoes were tested with the new bottle bioassay, and LC50/LC99 or OI50/OI99 values were determined for all insecticides. Variation was seen between laboratories in estimates for some mosquito species-insecticide combinations, while other test results were consistent. The variation was generally greater with transfluthrin and flupyradifurone than with the other compounds tested, especially against Anopheles species. Overall, the mean within-bioassay variability in mortality and oviposition inhibition were < 10% for most mosquito species-insecticide combinations. CONCLUSION: Our findings, based on the largest susceptibility dataset ever produced on mosquitoes, showed that the new WHO bottle bioassay is adequate for evaluating mosquito susceptibility to new and promising public health insecticides currently deployed for vector control. The datasets presented in this study have been used recently by the WHO to establish 17 new insecticide discriminating concentrations (DCs) for either Aedes spp. or Anopheles spp. The bottle bioassay and DCs can now be widely used to monitor baseline insecticide susceptibility of wild populations of vectors of malaria and Aedes-borne diseases worldwide.

Brucella abortus induces mast cell activation through TLR-2 and TLR-4.

The Gram-negative bacteria Brucella abortus is a major cause of brucellosis in animals and humans. The host innate immune response to B. abortus is mainly associated with phagocytic cells such as dendritic cells, neutrophils, and macrophages. However, as mast cells naturally reside in the main bacterial entry sites they may be involved in bacterial recognition. At present, little is known about the role of mast cells during B. abortus infection. The role of the innate immune receptors TLR2 and TLR4 in activation of mast cells by B. abortus (strain RB51) infection was analyzed in this study. The results showed that B. abortus did not induce mast cell degranulation, but did induce the synthesis of the cytokines IL-1ß, IL-6, TNF-α, CCL3, CCL4, and CCL5. Furthermore, B. abortus stimulated key cell signaling molecules involved in mast cell activation such as p38 and NF-κB. Blockade of the receptors TLR2 and TLR4 decreased TNF-α and IL-6 release by mast cells in response to B. abortus. Taken together, our results demonstrate that mast cells are activated by B. abortus and may play a role in inducing an inflammatory response during the initial phase of the infection.

Hipoacusia súbita asociada a depresión: síntoma inusual en adultos mayores infectados por Sars-CoV-2 / Sudden hearing loss associated with depression: an unusual symptom in older adults infected with Sars-CoV-2

Se comienza acumular información sobre las alteraciones en pacientes positivos a Covid-19, donde relacionan el virus con el daño del oído medio y oído interno, tanto en la porción vestibular como la auditiva en adultos mayores, generando episodios depresivos. Por tal razón, se propuso como objetivo evaluar la relación hipoacusia súbita asociada a depresión en adultos mayores infectados por Sars-CoV-2 atendidos en el Hospital Básico Pillaros, perteneciente al sector Ciudadela Ciudad Nueva, Ecuador 2020-2021. El estudio fue cuantitavo, descriptivo correlacional de corte transversal con una muestra de 87 pacientes >65 años positivos para Sars-CoV-2. Para la recolección de datos se aplicó el Test audiométrico y la escala de depresión geriátrica de Yesavage. El análisis de los datos fue con estadística descriptiva en base a frecuencias, porcentajes, IC 95% y X2 a través de SPSS. Como resultado 73,6% eran fememnino y 26,4% masculino, 54,0% tenían de 65-75 años, el tipo de presbiacusia más existente fue neural (31,2%) y coclear (31,0%). Así mismo, 81,6% presentaron signos de depresión, mientras que 18,4% no. En el test Vasayage 88,5% expresó no sentirse lleno de energía y 59,8% sienten temor a que algo malo suceda. Como conclusión, la presencia de trastornos auditivos constituye un problema para la comunicación de los adultos mayores que pudiese conllevar a estados depresivos, por ello, incentivar el desarrollo de investigaciones pudieran orientar hacia el desarrollo de alternativas de intervención temprana que favorezcan el mejoramiento de la calidad de vida de este grupo poblacional(AU)

Information is beginning to accumulate on the alterations in patients positive for Covid -19, where they relate the virus to damage to the middle ear and inner ear, both in the vestibular and auditory portions in older adults, generating depressive episodes. For this reason, the objective was to evaluate the relationship between sudden hearing loss associated with depression in older adults infected with Sars-CoV- treated at the Pillaros Basic Hospital, belonging to the Ciudadela Ciudad Nueva sector, Ecuador 2020-2021. The study was quantitative, descriptive correlational cross-sectional with a sample of 87 patients >65 years positive for Sars-CoV-2. For data collection, the audiometric test and the Yesavage geriatric depression scale were applied. The analysis of the data was with descriptive statistics based on frequencies, percentages, CI 95% and X2 through SPSS. As a result, 73.6% were female and 26.4% male, 54.0% were 65-75 years old, the most common type of presbycusis was neural (31.2%) and cochlear (31.0%). Likewise, 81.6% presented signs of depression, while 18.4% did not. In the Vasayage test, 88.5% expressed not feeling full of energy and 59.8% were afraid that something bad would happen. In conclusion, the presence of hearing disorders constitutes a problem for the communication of older adults that could lead to depressive states, therefore, encouraging the development of research could guide the development of early intervention alternatives that favor quality improvement. life of this population group(AU)

Accuracy of machine learning algorithms for the assessment of upper-limb motor impairments in patients with post-stroke hemiparesis: A systematic review and meta-analysis.

BACKGROUND: The assessment of motor function is vital in post-stroke rehabilitation protocols, and it is imperative to obtain an objective and quantitative measurement of motor function. There are some innovative machine learning algorithms that can be applied in order to automate the assessment of upper extremity motor function. OBJECTIVES: To perform a systematic review and meta-analysis of the efficacy of machine learning algorithms for assessing upper limb motor function in post-stroke patients and compare these algorithms to clinical assessment. MATERIAL AND METHODS: The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database. The review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The search was performed using 6 electronic databases. The meta-analysis was performed with the data from the correlation coefficients using a random model. RESULTS: The initial search yielded 1626 records, but only 8 studies fully met the eligibility criteria. The studies reported strong and very strong correlations between the algorithms tested and clinical assessment. The meta-analysis revealed a lack of homogeneity (I2 = 85.29%, Q = 48.15), which is attributable to the heterogeneity of the included studies. CONCLUSION: Automated systems using machine learning algorithms could support therapists in assessing upper extremity motor function in post-stroke patients. However, to draw more robust conclusions, methodological designs that minimize the risk of bias and increase the quality of the methodology of future studies are required.

Estrategias para mitigar hipoglucemias y variabilidad glucémica / Strategies to mitigate hypoglycemia and glycemic variability

La última década se ha destacado por los importantes avances en el desarrollo de nuevas tecnologías para pacientes que viven con diabetes mellitus (DM). Las innovaciones han estado orientadas principalmente a: mejorar la calidad de vida, reducir el impacto que genera la ocurrencia de hipoglucemias y reducir la carga de la enfermedad colaborando en la toma diaria de decisiones1. El monitoreo continuo de glucosa (MCG) es una herramienta que ha experimentado un importante avance al aportar información dinámica del estado metabólico en los pacientes y permitir la toma de decisiones, demostrado por un control metabólico estable, menores excursiones glucémicas, y una reducción significativa en la aparición y gravedad de las hipoglucemias2-5. Las presentes recomendaciones tienen como objetivo brindar herramientas rápidas para la interpretación de datos metabólicos y la consiguiente toma de decisiones terapéuticas. A tal fin se realizó una exhaustiva revisión de las principales guías y recomendaciones vigentes; posteriormente, el Grupo de Trabajo adaptó esa información según una serie de preguntas con criterio clínico práctico. El avance de los MCG es innegable, no solo en el desarrollo tecnológico, sino que se han convertido en una herramienta educativa para las personas con DM, su entorno y el equipo de salud al posibilitar un ajuste dinámico del tratamiento, prevenir complicaciones agudas y mejorar la calidad de vida. En esta ecuación enfatizamos la importancia de la educación diabetológica continua de la persona con DM y su entorno, participando activamente en la toma de decisiones para, de esta manera, cumplir con los objetivos propuestos: mejorar la calidad de vida, reducir la carga de la enfermedad y disminuir las excursiones glucémicas agudas.

The last decade has been highlighted by important advances in the development of new technologies for patients living with diabetes. The innovations have been oriented above all to improve the quality of life, reduce the impact generated by the occurrence of hypoglycemia and reduce the burden of the disease by collaborating in daily decision-making1. Continuous glucose monitoring (CGM) is a tool that has undergone significant progress, providing dynamic information on the metabolic status of patients, allowing decision making, demonstrated by stable metabolic control, lower glycemic excursions and a significant reduction in the occurrence and severity of hypoglycemia2-5. The purpose of these recommendations, developed by members of the Innovation Committee of the Argentine Society of Diabetes, is to provide rapid tools for the interpretation of metabolic data and the subsequent therapeutic decisionmaking. To this end, an exhaustive review of the main current guidelines and recommendations has been carried out, later the working group adapted this information according to a series of questions with practical clinical criteria. The progress of CGMs is undeniable, not only in technological development, but it has become an educational tool for people with diabetes, their environment, and the health team, offering the possibility of a dynamic adjustment of treatment, prevention of acute complications and improving quality of life. In this equation, we emphasize the importance of continuous diabetes education for the person with diabetes and their environment, actively participating in decision-making, and in this way, meeting the proposed objectives: improving quality of life, reducing the burden of disease, and decreasing acute glycemic excursions.

Recomendaciones para la práctica clínica sobre el manejo de la actividad física, ejercicio y deporte en niños, niñas y adolescentes con diabetes mellitus tipo 1 / Management of type 1 diabetes mellitus about physical activity, exercise and sports in children and adolescents

La presente recomendación busca brindar un marco de seguridad para la prescripción de actividad física en niños, niñas y adolescentes con diabetes mellitus tipo 1 (DM1), considerando la evaluación de las situaciones que puedan presentarse antes, durante y después de su práctica. Incluye las estrategias terapéuticas sobre el tipo de ejercicio, el control glucémico capilar (o mediante el uso de monitoreo continuo de glucosa, MCG) y la adecuación de la insulinoterapia y de la ingesta de hidratos de carbono. Se prioriza que, para optimizar los beneficios del ejercicio como parte del tratamiento de la DM1, es importante una completa y constante educación diabetológica para el paciente y sus cuidadores brindada por un equipo interdisciplinario entrenado en el manejo integral de niños, niñas y adolescentes con DM1.

It includes therapeutic strategies on the type of exercise, intensive capillary glycemic control or through the use of continuous glucose monitoring (CGM) and the adequacy of insulin therapy and carbohydrate intake. It is prioritized that to optimize the benefits of exercise as part of the treatment of DM1, a complete and constant diabetes education is important, provided by an interdisciplinary team trained in the comprehensive management of children and adolescents with DM1

Susceptibility to Organophosphates in Culex quinquefasciatus from Colombia.

Susceptibility to organophosphates was evaluated in 2 populations of Culex quinquefasciatus from the department of Atlantico, Colombia. Bioassays for temephos, malathion, and pirimiphos-methyl were performed with 3rd-stage larvae and adult females of Cx. quinquefasciatus from the municipalities of Soledad and Puerto Colombia, following the methods of the World Health Organization and Centers for Disease Control and Prevention, respectively. The median lethal concentration (LC50) and 90% lethal concentration (LC90) resistance ratios (RRLC50 and RRLC90) were determined for each insecticide in the field populations evaluated, using the Cartagena strain as the susceptible control. Relative to LC50 and LC90 of the Cartagena strain, the population from Puerto Colombia was moderately resistant to temephos (RRLC50 5.7-fold) and malathion (RRLC50 8.6-fold, RRLC90 9-fold) and susceptible to pirimiphos-methyl (RRLC50 and RRLC90 < 5-fold). The population from Soledad was susceptible to temephos and pirimiphos-methyl (RRLC50 and RRLC90 < 5-fold) and showed moderate resistance to malathion (RRLC50 7.5-fold). It is important to emphasize that routine monitoring of insecticide resistance in Cx. quinquefasciatus helps us detect resistance early and improve the effectiveness of control strategies.

Estrategias para mitigar hipoglucemias y variabilidad glucémica / Strategies to mitigate hypoglycemia and glycemic variability

Resumen La última década se ha destacado por los importantes avances en el desarrollo de nuevas tecnologías para pacientes que viven con diabetes mellitus (DM). Las innovaciones han estado orientadas principalmente a: mejorar la calidad de vida, reducir el impacto que genera la ocurrencia de hipoglucemias y reducir la carga de la enfermedad colaborando en la toma diaria de decisiones1. El monitoreo continuo de glucosa (MCG) es una herramienta que ha experimentado un importante avance al aportar información dinámica del estado metabólico en los pacientes y permitir la toma de decisiones, demostrado por un control metabólico estable, menores excursiones glucémicas, y una reducción significativa en la aparición y gravedad de las hipoglucemias2-5. Las presentes recomendaciones tienen como objetivo brindar herramientas rápidas para la interpretación de datos metabólicos y la consiguiente toma de decisiones terapéuticas. A tal fin se realizó una exhaustiva revisión de las principales guías y recomendaciones vigentes; posteriormente, el Grupo de Trabajo adaptó esa información según una serie de preguntas con criterio clínico práctico. El avance de los MCG es innegable, no solo en el desarrollo tecnológico, sino que se han convertido en una herramienta educativa para las personas con DM, su entorno y el equipo de salud al posibilitar un ajuste dinámico del tratamiento, prevenir complicaciones agudas y mejorar la calidad de vida. En esta ecuación enfatizamos la importancia de la educación diabetológica continua de la persona con DM y su entorno, participando activamente en la toma de decisiones para, de esta manera, cumplir con los objetivos propuestos: mejorar la calidad de vida, reducir la carga de la enfermedad y disminuir las excursiones glucémicas agudas.

Abstract The last decade has been highlighted by important advances in the development of new technologies for patients living with diabetes. The innovations have been oriented above all to improve the quality of life, reduce the impact generated by the occurrence of hypoglycemia and reduce the burden of the disease by collaborating in daily decision-making1. Continuous glucose monitoring (CGM) is a tool that has undergone significant progress, providing dynamic information on the metabolic status of patients, allowing decision making, demonstrated by stable metabolic control, lower glycemic excursions and a significant reduction in the occurrence and severity of hypoglycemia2-5. The purpose of these recommendations, developed by members of the Innovation Committee of the Argentine Society of Diabetes, is to provide rapid tools for the interpretation of metabolic data and the subsequent therapeutic decisionmaking. To this end, an exhaustive review of the main current guidelines and recommendations has been carried out, later the working group adapted this information according to a series of questions with practical clinical criteria. The progress of CGMs is undeniable, not only in technological development, but it has become an educational tool for people with diabetes, their environment, and the health team, offering the possibility of a dynamic adjustment of treatment, prevention of acute complications and improving quality of life. In this equation, we emphasize the importance of continuous diabetes education for the person with diabetes and their environment, actively participating in decision-making, and in this way, meeting the proposed objectives: improving quality of life, reducing the burden of disease, and decreasing acute glycemic excursions.
