RESUMEN

This systematic review addressed the issue of the abuse and neglect of older women (age 60 and over) in rural and remote areas, examining these phenomena's prevalence, risk and protective factors, consequences, and associated perceptions. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Arksey and O'Malley methodological framework, peer-reviewed articles published until September 2023 were identified in six electronic databases. Out of the manuscripts initially identified (n = 219), 28 articles met the selection criteria. The study's quality was assessed using the Mixed Methods Appraisal Tool. The included studies provided a comprehensive overview of this phenomenon, encompassing data from 6,579 older rural women. Prevalence rates of abuse and neglect exhibited wide variability, with an average of 27.3%. Among the risk factors, financial dependence and incapacity stood out, while higher income and education levels were protective factors, among others. Emotional/psychological abuse emerged as the most common form, with significant impacts on older women's physical and mental health. Cultural norms and gender expectations also influenced perceptions of abuse and victims' coping mechanisms. In a context in which access to specialized resources and services is hampered by significant limitations, community awareness and education prove vital to address this issue, which positions social work as key to addressing these challenges. The prevalence of abuse against older rural women is significant. Emotional abuse stands out as a major issue, underscoring the need for comprehensive interventions accounting for cultural and gender factors.

RESUMEN

The relationship between growth hormone (GH) excess and cancer is a controversial matter. Until 2016, most studies in patients with acromegaly found links with colon and thyroid neoplasms. However, recent studies found increased risks in gastric, breast, and urinary tract cancer also. Concordantly, clinical situations where GH and insulin-like growth facto-I deficits exist are indeed associated with diminished malignancy incidence. In line with these observations, gain-of-function mutations of various enzymes belonging to the GH and IGF-I signaling pathways have been associated with increased carcinogenesis; similarly, loss-of-function mutations of other enzymes that usually work as tumor repressors are also associated with augmented cancer risk. In a study performed in Ecuador, it was demonstrated that subjects in the Ecuadorian cohort with Laron syndrome (ELS), who have a mutant GH receptor and greatly diminished GH and IGF-I signaling, display diminished incidence of cancer. Along with absent action of GH and IGF-I, ELS individuals also have low serum insulin levels and decreased insulin resistance. Furthermore, hyperglycemia and hyperinsulinemia are indispensable for fast cell mitosis, including that of those cells present in the benign and malignant neoplasms. Notably, and despite their obesity, subjects with the ELS display normoglycemia and hypo-insulinemia, along with diminished incidence of malignancies. We believe that the dual low-IGF-I/low insulin serum levels are responsible for the cancer protection, especially considering that the insulin/INSR signaling is a central site for energy generation in the form of ATP and GDP, which are indispensable for all and every GH/IGF-I physiologic as well as pathologic events.

RESUMEN

OBJECTIVES: In 2019, >71 million children aged <5 had spent their entire lives in conflict-affected settings. Compounding adversities including violence, poverty, and displacement have immediate and long-term effects on early childhood development, health, behavior, and well-being. In response, adaptations of Reach Up have been implemented in conflict and crisis settings. METHODS: This article uses exploratory multiple case study methodology, drawing from implementation and qualitative data from 3 interventions: a mobile phone-based intervention promoting nurturing care among Rohingya and crisis-affected host communities in Bangladesh; Reach Up amid acute violence and displacement in Northeast Syria; and Reach Up group sessions and home visits integrated with health services for an indigenous population in Venezuela. RESULTS: In Bangladesh, tailoring interactive voice response messages improved responsiveness to the developmental needs of young children, yet complementary in-person services were identified as a key program enhancement. In Syria, rapid adaptations of Reach Up addressed the needs of families in acute crisis, including social-emotional learning games for school-aged children. In Venezuela, Reach Up, coupled with complementary lactation counseling, yielded high rates of uptake and satisfaction, and children's language development was highlighted as a key area of growth. CONCLUSIONS: Recommendations to promote early childhood development in crisis and conflict settings include: (1) cultural adaptation based on a holistic understanding of children and caregivers' needs; (2) the integration of child and family safety and linkages with complementary services on the basis of community needs and priorities, and (3) the importance of designing for scale through blended models and costing analyses.

RESUMEN

Meta-analyses from 2018-2022 have shown that obesity increases the risk of various cancers such as acute myeloid lymphoma, chronic myeloid lymphoma, diffuse beta cell lymphoma, Hodgkin's lymphoma, leukemia, multiple myeloma, non-Hodgkin's lymphoma, bladder, breast, cholangiocarcinoma, colorectal, ovarian, esophageal, kidney, liver, prostate, thyroid, and uterus. Contextually, obesity, and its comorbidities, is the largest, most lethal pandemics in the history of mankind; hence, identification of underlying mechanisms is needed to adequately address this global health threat. Herein, we present the metabolic and hormonal mechanisms linked to obesity that might etiologically contribute to neoplasia, including hyperinsulinemia and putative places in the insulin-signaling pathway. Excess insulin, acting as a growth factor, might contribute to tumorigenesis, while abundant ATP and GDP supply the additional energy needed for proliferation of rapidly dividing cells. Our observations in the Ecuadorian cohort of subjects with Laron syndrome (ELS) prove that obesity does not always associate with increased cancer risk. Indeed, despite excess body fat from birth to death, these individuals display a diminished incidence of cancer when compared to their age- and sex-matched relatives. Furthermore, in cell cultures exposed to potent oxidizing agents, addition of ELS serum induces less DNA damage as well as increased apoptosis. ELS individuals have absent growth hormone (GH) counter-regulatory effects in carbohydrate metabolism due to a defective GH receptor. The corresponding biochemical phenotype includes extremely low basal serum concentrations of insulin and insulin-like growth factor-I, lower basal glucose and triglyceride (TG) levels, and diminished glucose, TG, and insulin responses to orally administered glucose or to a mixed meal.

RESUMEN

Los quistes epidermoides son patologías benignas que se originan cuando células germinativas quedan atrapadas dentro de los arcos branquiales durante su cierre. Su prevalencia es baja, siendo aún menos prevalente su par, el quiste dermoide. Se presenta el caso clínico de una paciente de 17 años, de sexo femenino que debuta con aumento de volumen en piso de la cavidad, bilateral (de larga data), con obstrucción parcial de vía aérea, dificultad a la fonación y deglución. La tomografía computarizada entrega una imagen hipodensa, autolimitada, en los espacios submandibular y sublingual. Como hipótesis diagnóstica se sugiere un quiste dermoide o epidermoide. La paciente es intervenida y la muestra entregada a anatomopatología. El diagnóstico definitivo corrobora la hipótesis presuntiva de quiste epidermoide.


Epidermoid cysts are benign pathologies that originate when germinative cells become trapped within the branchial arches during their closure. Its prevalence is low, and its peer, the dermoid cyst, is even less prevalent. The clinical case is presented of a 17-year-old female patient who presents a bilateral increase in the oral cavity (long- standing), with partial obstruction of the airway, difficulty in phonation and swallowing. The computed tomography provides a hypodense, self-limited image in the submandibular and sublingual spaces. A dermoid or epidermoid cyst is suggested as a diagnostic hypothesis. The patient undergoes surgery, and the sample is delivered to pathology. The definitive diagnosis corroborates the presumptive hypothesis of an epidermoid cyst.

RESUMEN

Abstract In Argentina there are no reports on Aspergillus fumigatus fumagillin-producingstrains. In this study we describe the isolation and mycotoxin production capacity of ten A.fumigatus strains isolated from farm and clinical samples. Farm strains were isolated frommilk samples taken from dairy cows in Córdoba province, some of which were associated withsubclinical mastitis. A culture medium was defined to optimize fumagillin production and adetection method was developed by HPLC chromatography. It is known that in addition to thehost immune status, strain virulence is a fundamental characteristic that will determine itspathogenicity and, in this sense, fumagillin is considered to be among the virulence factors. Inthe present work, all the strains tested for the production of fumagillin were able to synthesizeit, highlighting that the strain A. fumigatus RC2243, from a milk sample from a cow with clinicalmastitis, was the most productive. The existence of fumagillin-producing strains represents apotential risk of mycotoxins being transferred to raw milk, constituting a public health risk.


Resumen En Argentina no existen reportes sobre cepas de Aspergillus fumigatus productoras de fumagilina. En este trabajo se describe el aislamiento y la producción de dicha micotoxina clínicaspor 10 cepas, provenientes del medioambiente rural y aisladas de muestras clínicas. Las cepasde origen rural fueron aisladas de vacas lecheras en tambos de la provincia de Córdoba, yalgunas de esas cepas se asociaron a casos de mastitis subclínica. Se definió la composición deun medio de cultivo para optimizar la producción de fumagilina y se desarrolló un método decromatografía HPLC para su determinación. Es conocido que, además del estado inmunitario delhuésped, la virulencia de la cepa es una de las características fundamentales que determinansu potencial patogénico y, en este sentido, la fumagilina es considerada un factor de virulencia. En el presente trabajo todas las cepas estudiadas fueron capaces de sintetizarla y la cepa A.fumigatus RC2243, proveniente de leche de una vaca con mastitis subclínica, se destacó comola cepa más productora. La existencia de cepas productoras de fumagillina representa un riesgopotencial por el pasaje de dicha micotoxina a la leche, lo cual constituye un problema para lasalud pública.

RESUMEN

Narcolepsy is a chronic and disabling neurological disorder characterized by excessive daytime sleepiness (EDS) and cataplexy. Historically, some medications have demonstrated efficacy in managing EDS and cataplexy symptoms. However, some patients cannot tolerate them, become refractory, or may use concomitant medications that preclude the use due to drug-drug interaction. Therefore, there is a necessity to explore the efficacy of new treatments, such as solriamfetol (JZP-110), a 2019 FDA-approved drug indicated to improve wakefulness in adults with EDS associated with narcolepsy. We conducted this systematic review to investigate the effectiveness of solriamfetol in EDS and cataplexy, and the drug's overall safety. For this study, we used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and MOOSE protocol. After an initial search of 119 papers, we included four clinical trials to investigate and analyze the use of solriamfetol for the treatment of narcolepsy. Solriamfetol was proven to improve objective measures of EDS in all clinical trials. We conducted this systematic review using objective measures such as the Epworth Sleepiness Scale and the Maintenance of Wakefulness Test. Overall, cataplexy was not formally evaluated in the four clinical trials; however, it demonstrated that EDS improved in patients with and without cataplexy. More clinical trials are needed to analyze the efficacy of solriamfetol on cataplexy. The effect of solriamfetol in EDS seems to be conclusive.

RESUMEN

Ramsay Hunt syndrome is a rare complication of herpes zoster that results from reactivation of varicella-zoster virus in the geniculate ganglion of the VII cranial nerve. Immunosuppression can lead to reactivation of latent varicella-zoster virus, resulting in herpes zoster. Here, we present a case of Ramsay Hunt syndrome in a patient with ulcerative colitis under treatment with infliximab. LEARNING POINTS: Ramsay Hunt syndrome is a rare form of herpes zoster and characterized by the presence of otalgia, facial palsy, vertigo and vesicular rash in the external ear or on the oropharynx.Treatment with TNF inhibitors increases the risk of its development.Although not generally recommended, vaccination may reduce the risk of herpes zoster recurrence during TNF inhibitor therapy.

RESUMEN

Human size is achieved by the coordinated expression of many genes. From conception to adulthood, a given genomic endowment is modified by highly variable environmental circumstances. During each stage of a person's life, distinct nutritional and hormonal influences continuously shape growing physical features until mature characteristics are attained. Underlying processes depend on precise provision of substrates and energy extracted by insulin action from nutrients, which allows cell proliferation, differentiation, and survival, under the concerted actions of growth hormone and insulin-like growth factor-I (IGF-I). It should be noted that growth and metabolic signaling pathways are interdependent and superimposed at multiple levels. Attainment of a fully developed human phenotype should be considered as a harmonious increment in body size rather than a simple increase in height. From this perspective we herein analyze adult features of individuals with an inactive growth hormone receptor, who consequently have severely diminished concentrations of serum insulin and endocrine IGF-I.

RESUMEN

The Ecuadorian cohort of subjects with LS has taught us valuable lessons since the late 80's. We have learned about migration of Sephardic Jews to our country, their isolation in remote hamlets and further inbreeding. These geographical, historical and social determinants induced dissemination of a growth hormone (GH) receptor mutation which widely occurred in those almost inaccessible villages. Consequently, the world's largest Laron syndrome (LS) cohort emerged in Loja and El Oro, two of the southern provinces of Ecuador. We have been fortunate to study these patients since 1987. New clinical features derived from GH insensitivity, their growth patterns as well as treatment with exogenous insulin-like growth factor I (IGF-I) have been reported. Novel biochemical characteristics in the field of GH insensitivity, IGFs, IGF binding proteins (BP) and their clinical correlates have also been described. In the last few years, studies on the morbidity and mortality of Ecuadorian LS adults surprisingly demonstrated that despite obesity, they had lower incidence of diabetes and cancer than their relatives. These events were linked to their metabolic phenotype of elevated but ineffective GH concentrations and low circulating IGF-I and IGFBP-3. It was also noted that absent GH counter-regulation induces a decrease in insulin resistance (IR), which results in low but highly efficient insulin levels which properly handle metabolic substrates. We propose that the combination of low IGF-I signaling, decreased IR, and efficient serum insulin concentrations are reasonable explanations for the diminished incidence of diabetes and cancer in these subjects.

RESUMEN

We present isotopic and morphometric evidence suggesting the migration of farmers in the southern Andes in the period AD 1270-1420, leading up to the Inka conquest occurring ~ AD 1400. This is based on the interdisciplinary study of human remains from archaeological cemeteries in the Andean Uspallata Valley (Argentina), located in the southern frontier of the Inka Empire. The studied samples span AD 800-1500, encompassing the highly dynamic Late Intermediate Period and culminating with the imperial expansion. Our research combines a macro-regional study of human paleomobility and migration based on a new strontium isoscape across the Andes that allows identifying locals and migrants, a geometric morphometric analysis of cranio-facial morphology suggesting separate ancestral lineages, and a paleodietary reconstruction based on stable isotopes showing that the migrants had diets exceptionally high in C4 plants and largely based on maize agriculture. Significantly, this migration influx occurred during a period of regional demographic increase and would have been part of a widespread period of change in settlement patterns and population movements that preceded the Inka expansion. These processes increased local social diversity and may have been subsequently utilized by the Inka to channel interaction with the local societies.

RESUMEN

The National Center for Advancing Translational Sciences has called for more comprehensive research with priority populations to reduce disparities and for the development of additional resources to assist researchers in implementing these recommendations. Here we report the development and initial evaluation of five Priority Populations Toolkits, which are resources developed by the University of Illinois Center for Clinical and Translational Science to meet these goals. Three aims guide the content: increasing knowledge, facilitating communication, and improving research design. Materials were curated from scientific literature reviews and Internet searches and revised iteratively. Analytics and user surveys provide information about usage. In 22 months, 387 unique users accessed the toolkits. The top reason for usage was to improve research recruitment. Comprehensive toolkits for working with priority populations show promising potential for increasing knowledge and readiness to work with underrepresented populations. Further toolkit development and evaluation of effectiveness are warranted.

RESUMEN

INTRODUCTION: The aim of this in vivo study was to compare the accuracy of 3 electronic apex locators (EALs) (Root ZX mini [J Morita Corp, Tokyo, Japan], Apex ID [SybronEndo, Glendora, CA], and Propex Pixi [Dentsply Maillefer, Ballaigues, Switzerland]) to determine the working length. METHODS: Thirty single-rooted human teeth that were scheduled for extraction were selected for the study. Electronic measurements were performed with the 3 EALs. After the teeth had been extracted, a #10 K-file was used to determine the actual working length, which was established at 0.5 mm short of the major foramen. The data were statistically analyzed with analysis of variance (α = 0.05). RESULTS: No significant differences were found among the experimental groups (P > .05). The mean distance from the actual working length to the file tip was 0.163 ± 0.032 mm when Root ZX mini was used, 0.343 ± 0.032 mm for Propex Pixi , and 0.012 ± 0.008 mm for Apex ID. CONCLUSIONS: Under the in vivo conditions of this study, no statistically significant differences were observed among the 3 EALs.

RESUMEN

RESUMEN: Objetivo: Evaluar el grado de concordancia entre las prevalencias de trastornos articulares inflamatorios (TAI) de las Articulaciones Temporomandibulares (ATM), obtenidas con los Criterios Diagnósticos de Investigación para Trastornos Temporomandibulares (RDC/TMD) y los Criterios Diagnósticos para Trastornos Temporomandibulares (DC/TMD). Materiales y métodos: 59 pacientes adultos chilenos fueron examinados según el Eje I de los RDC/TMD y el Eje I de los DC/TMD para determinar la prevalencia de TAI. Luego se compararon los resultados obtenidos de cada protocolo con el test Kappa de Cohen para evaluar la concordancia entre ambos. Resultados: La prevalencia de TAI para ambos criterios fue de 22%, con una concordancia casi perfecta (kappa=0,91). Al comparar las prevalencias de TAI por articulación, se obtuvo un grado de acuerdo sustancial (kappa=0,77) para la ATM derecha y un grado de acuerdo casi perfecto (kappa=0,94) para la ATM izquierda. Al comparar las prevalencias de TAI según género y edad se obtuvo una concordancia estadísticamente significativa en la mayoría de los casos. Conclusión: Hay concordancia estadísticamente significativa entre los datos obtenidos con los RDC/TMD y los DC/TMD, en el diagnóstico de trastornos articulares inflamatorios.


ABSTRACT: Aim: To assess the agreement between the prevalence of inflammatory joint disorders (IJD) obtained with Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Materials and methods: 59 Chilean adult patients were examined according to Axis I of the RDC/TMD and Axis I of the DC/TMD to determine prevalence of IJD. Then, the results obtained from each protocol were compared with Cohen's Kappa test to assess the agreement between them. Results: The prevalence of IJD for both criteria was 22%, with almost perfect agreement (kappa = 0.91). When comparing the prevalences of IJD per joint, a substantial agreement (kappa = 0.77) was obtained for the right TMJ and an almost perfect agreement (kappa = 0.94) for the left TMJ. When comparing the prevalences of IJD according to gender and age, a statistically significant agreement was obtained in the majority of cases. Conclusion: There is statistically significant agreement between the data obtained with the RDC/TMD and the DC/TMD, in the diagnosis of inflammatory joint disorders.

RESUMEN

BACKGROUND: Artificial Mitochondrial Transfer or Transplant (AMT/T) can be used to reduce the stress and loss of viability of damaged cells. In MitoCeption, a type of AMT/T, the isolated mitochondria and recipient cells are centrifuged together at 4 °C and then co-incubated at 37 °C in normal culture conditions, inducing the transfer. Ultraviolet radiation (UVR) can affect mitochondria and other cell structures, resulting in tissue stress, aging, and immunosuppression. AMT/T could be used to repair UVR cellular and mitochondrial damage. We studied if a mitochondrial mix from different donors (Primary Allogeneic Mitochondrial Mix, PAMM) can repair UVR damage and promote cell survival. RESULTS: Using a simplified adaption of the MitoCeption protocol, we used peripheral blood mononuclear cells (PBMCs) as the recipient cell model of the PAMM in order to determine if this protocol could repair UVR damage. Our results showed that when PBMCs are exposed to UVR, there is a decrease in metabolic activity, mitochondrial mass, and mtDNA sequence stability as well as an increase in p53 expression and the percentage of dead cells. When PAMM MitoCeption was used on UVR-damaged cells, it successfully transferred mitochondria from different donors to distinct PBMCs populations and repaired the observed UVR damage. CONCLUSION: Our results represent an advancement in the applications of MitoCeption and other AMT/T. We showed that PBMCs could be used as a PAMM source of mitochondria. We also showed that these mitochondria can be transferred in a mix from different donors (PAMM) to UVR-damaged, non-adherent primary cells. Additionally, we decreased the duration of the MitoCeption protocol.

RESUMEN

BACKGROUND: A survey on Fusarium species and moniliformin (MON) occurrence in sorghum grains collected from one of the main sorghum-producing areas of Argentina was conducted. Also, growth of F. thapsinum, one of the main sorghum pathogens, and MON production under different water activity (aw ) conditions on a sorghum-based medium were determined. RESULTS: Infection of sorghum grains by Fusarium species ranged from 82.5 to 99%; closely related species F. verticillioides, F. thapsinum and F. andiyazi were the most frequently recovered, followed by F. proliferatum and F. subglutinans. By sequencing a portion of the translation elongation factor-1α (TEF-1α) gene and by maximum parsimony analysis, F. verticillioides and closely related species were identified as F. thapsinum, F. andiyazi and F. verticillioides. Species within the F. graminearum species complex (FGSC) were isolated in high frequency. Maximum growth rates of 12 F. thapsinum strains were obtained at 0.995 aw . All evaluated strains were able to produce MON at all aw values tested, but MON production was higher at 0.995-0.982 aw . MON was detected in 41% of the samples at levels ranging from 363.2 to 914.2 µg kg-1 . CONCLUSION: This study provides new data on the occurrence of Fusarium species in sorghum grains destined for animal consumption in Argentina. The production of MON at different aw values showed that the toxin can be produced under field conditions. The risk to livestock exposed to daily low levels of MON associated with the toxin occurrence in the sorghum grains analyzed is unknown. © 2018 Society of Chemical Industry.

RESUMEN

Aspergillus fumigatus, the major etiological agent of human and animal aspergillosis, is a gliotoxinogenic species into section Fumigati commonly found in contaminated animal environments. In dairy herds, exposed areas of lactating cows, as mammalian glandule, can be easily contaminated by them. This study was aimed to identify A. fumigatus sensu lato strains (identified based on morphology) isolated from raw cow milk at species level, by morphological and molecular techniques, and to estimate their genetic variability. Forty-five A. fumigatus strains showed similar RAPD profiles (generated with PELF and URP1F primers) to each other and to A. fumigatus sensu stricto reference strains; also, they were almost identical to clinical human and feed-borne A. fumigatus strains included in the assay, since their similarity coefficient ranged from 0.7 to 1.00. Therefore, all strains were characterized as belonging to A. fumigatus sensu stricto species. This result was supported by sequencing the benA gene of selected strains and by maximum parsimony analysis. In addition, RAPD fingerprinting demonstrated intra-specific genetic variability into the A. fumigatus sensu stricto cluster. The results found in this study strengthen the fact that A. fumigatus sensu stricto is the predominant species in the Aspergillus section Fumigati found in animal environments such as dairy herd environments, while other species such as A. novofumigatus, A. fumigatiaffinis, A. udagawae and A. lentulus may be rarely isolated. Since no differences between animal and human strains were observed they can become pathogenic also for farm handlers'. Moreover, the presence of A. fumigatus sensu stricto in raw cow milk is probably a very important risk factor since milk and its by-products are generally indented for human consumption, then gliotoxin could be transferred to them.

RESUMEN

This study describes the use of the Internet for health information research by patients attending a gynecologic oncology practice and examines the association between its use and anxiety. A self-administered survey assessed patients' demographic information and Internet use. The Hospital Anxiety and Depression Scale (HADS) and the State-Trait Anxiety Inventory (STAI) were administered concurrently. Of 212 patients who consented to the study, 98 (46%) had an appointment because of a cancer diagnosis. Of 199 respondents, 91 (46%) reported searching the Internet for information about their condition. Internet searching was unassociated with race/ethnicity and positively associated with education level, annual household income, and married/partnered civil status. Only 16% of the patients reported that a health-care provider recommended use of the Internet for research. Comparing patients who used the Internet for research with those who did not, the STAI state and trait anxiety scores were similar. The HADS anxiety subscale score was higher for those who used the Internet versus those who did not, which suggests heightened anxiety. Internet use for research is common in gynecologic oncology patients, and its use is associated with increased anxiety. Physicians can use this medium to educate patients about their disease, build trust, and alleviate fear.
