Basal characteristics of patients who responded to Ovarian Fragmentation for Follicular Activation (OFFA) or In Vitro Activation (IVA): a systematic review and meta-analysis.

A systematic review and meta-analysis were performed to identify if there is a subset of patients with POI who are more likely to show follicular growth after ovarian fragmentation for follicular activation (OFFA) or in vitro activation (IVA). Five studies met inclusion criteria for meta-analysis with a total of 164 patients. Forty-three patients showed follicle development (26.21%). Of those, the pregnancy rate was 35.58% (11/43) and the live birth rate was 20.93% (9/43). Our meta-analysis showed that age was not associated with follicle growth. However, lower baseline FSH, lower duration of amenorrhea/diagnosis, and presence of follicles remaining in biopsy were statistically significant for follicle development. Patients with basal characteristics mentioned before may have more chances to show follicle growth after OFFA or IVA. Taking into account that approximately 20% of patients with follicle growth had live birth, these results are very promising. Given the overall certainty of evidence, future studies are needed to confirm said results.

Rewarding Effects of the Hallucinogen 4-AcO-DMT Administration and Withdrawal in Rats: A Challenge to the Opponent-Process Theory.

According to the opponent-process theory of drug addiction, the intake of an addictive substance initiates two processes: a rapid primary process that results in the drug's rewarding effects, and a slower opponent process that leads to the aversive motivational state of drug aftereffects. This aversive state is integral in the desire, pursuit, and maintenance of drug use, potentially leading to dependence and addiction. However, current observational and experimental evidence suggests that the administration of a 5-hydroxytryptamine receptors-type 2A (5-HT2A) agonist, while capable of inducing a positive mental state in humans, may not generate the behavioral patterns typically associated with drugs of abuse. In this study, we found that administering the 5-HT2A agonist 4-Acetoxy-N,N-dimethyltryptamine fumarate (4-AcO-DMT) did not result in place preference in male rats compared to control saline administration 24 h later, after the drug has been cleared from the organism. However, in a modified place preference test where only the acute motivational effects of the drug were evaluated (excluding withdrawal), 4-AcO-DMT was found to be rewarding. Furthermore, in another modified place preference test where only the motivational effects of drug withdrawal were evaluated (excluding the acute effects of drug administration), the 24-hour aftereffect of 5-HT2A agonist administration also resulted in a robust place preference. Therefore, while 4-AcO-DMT administration was able to induce place preference, its 24-hour aftereffect also produced a strong reward. In the counterbalanced test, this reward from the aftereffect effectively overshadowed its acute rewarding properties, which could potentially create a false impression that 4-AcO-DMT lacks motivational properties. This suggests that 5-HT2A agonist administration follows a different dynamic than that proposed by the opponent-process theory of motivation and implies that the administration of 5-HT2A agonists may lead to behavioral patterns less typical of drugs associated with addiction.

Adecuación del esfuerzo terapéutico: retos en pediatría / Adequacy of therapeutic effort: Challenges in pediatrics

La adecuación del esfuerzo terapéutico reemplaza la expresión limitación terapéutica y se define como la decisión de no iniciar medidas diagnósticas y terapéuticas o de suspenderlas en respuesta a la condición del paciente, para evitar conductas potencialmente inapropiadas y redireccionar los objetivos de tratamiento hacia el confort y el bienestar. En la población pediátrica, esta decisión es aún más desafiante debido a la naturaleza de la relación médico-paciente-familia y a la escasez de guías que orienten su implementación. La adecuación del esfuerzo terapéutico está enmarcada en principios éticos y legales, pero existen diversos retos a nivel práctico. Cada proceso de adecuación es único y dinámico, y debe abordarse contemplando a quién realizarlo, cuándo, cómo y con qué medidas.

The term "therapeutic limitation" has been replaced by "adequacy of therapeutic effort" and is defined as the decision to withhold or withdraw diagnostic and therapeutic measures in response to the patient's condition, avoiding potentially inappropriate behaviors and redirectong treatment goals towards comfort and well-being. In the pediatric population, this decision is even more challenging given the nature of the physician-patient-family relationship and the paucity of guidelines to address treatment goals. The adequacy of therapeutic effort is framed by ethical and legal principles, but, in practice, there are several challenges. Each adequacy process is unique and dynamic, and should be addressed by taking into account with what measures, how, when, and in whom it should be implemented

Amapola, lindísima amapola: de los opiáceos y los opioides, utilidad y riesgos / Poppy, beautiful poppy: opiates and opioids, utility and risks

Resumen El opio y sus derivados, y recientemente los opioides, han acompañado a la humanidad desde las civilizaciones más antiguas hasta la actualidad. Sus efectos analgésicos, hipnóticos y placenteros no pasaron desapercibidos para los antiguos, los consideraron de utilidad médica y beneficiosa para el estado de ánimo. Hoy en día no existe otro tipo de medicamentos que puedan tratar el dolor más intenso tan eficientemente como estos potentes analgésicos. Sin embargo, el uso médico y recreativo de los opiáceos y los opioides conlleva riesgos para la salud, como la tolerancia, la hiperalgesia y la adicción. Actualmente, además de ser indiscutiblemente el tratamiento médico más poderoso para mitigar el sufrimiento ocasionado por el dolor, se ha convertido también en un problema de salud pública debido a la alta cantidad de personas con trastorno por uso de opioides y por las muertes ocasionadas por sobredosis. En esta revisión se hará mención de las bondades de los opiáceos y opioides, y también de los efectos no deseados que estos producen.

Abstract Opium and its derivatives, and recently the opioids have accompanied the humankind since the ancient civilizations to the present day. Its analgesic, hypnotic and pleasant effects did not go unnoticed by ancient people, which considered most of these effects of medical utility and noticed that they had remarkable mood benefits. Currently, there are no other kind of drugs that can palliate intense pain as efficiently as these powerful analgesics. However, the medical and recreational use of opiates and opioids may carry health risks such as tolerance, hyperalgesia, and addiction. Nowadays, in addition to being indisputably the most powerful medical treatment to alleviate the suffering caused by pain, it has also become a public health problem due to the high number of people with opioid use disorder that have facilitated deaths caused by opioids overdose. In this review we will discuss the medical benefits of opiates and opioids, as much as the unwanted effects they produce.

Intersectionality of Socioecological Factors Associated With Cognitive Function Among Older Women With HIV in the United States: A Structural Equation Model Analysis Using Data From the Women's Interagency HIV Study.

ABSTRACT: Increased life expectancy of people with HIV has health implications including the intersection of the long-term use of antiretroviral treatment, inflammatory events, and age-related immunosenescence. In a cross-sectional study utilizing using the Socio-Eecological Model, we identified pathways of cognitive function (CF) among 448 women with HIV, 50 years and older. A structural equation model showed the direct effects of mood (ß = -0.25, p < .01), comorbidities (ß = --0.13, p < .05), race (ß = --0.13, p < .05), and abuse (ß = 0.27, p < .001) on the latent variable CF. Substance and alcohol use, depressive symptoms, cigarette smoking, and the number of comorbidities are important considerations when designing interventions utilizing using a multi-level and intersectional lens to maximize positive CF outcomes.

Seguridad de las drogas biológicas y sintéticas dirigidas utilizadas en pacientes con enfermedades reumáticas inmunomediadas. Datos del registro BIOBADASAR 3.0 / Safety of biological and targeted synthetic drugs in patients with immune-mediated rheumatic diseases. Data from the BIOBADASAR 3.0 registry

Introducción: conocer la seguridad de las drogas actualmente disponibles para el tratamiento de las enfermedades reumáticas es muy importante al momento de tomar decisiones terapéuticas objetivas e individualizadas en la consulta médica diaria. Asimismo, datos de la vida real amplían el conocimiento revelado por los ensayos clínicos. Objetivos: describir los eventos adversos (EA) reportados, estimar su frecuencia e identificar los factores relacionados con su desarrollo. Materiales y métodos: se utilizaron datos BIOBADASAR, un registro voluntario y prospectivo de seguimiento de EA de tratamientos biológicos y sintéticos dirigidos en pacientes con enfermedades reumáticas inmunomediadas. Los pacientes son seguidos hasta la muerte, pérdida de seguimiento o retiro del consentimiento informado. Para este análisis se extrajeron datos recopilados hasta el 31 de enero de 2023. Resultados: se incluyó un total de 6253 pacientes, los cuales aportaron 9533 ciclos de tratamiento, incluyendo 3647 (38,3%) ciclos sin drogas modificadoras de la enfermedad biológicas y sintéticas dirigidas (DME-b/sd) y 5886 (61,7%) con DME-b/sd. Dentro de estos últimos, los más utilizados fueron los inhibidores de TNF y abatacept. Se reportaron 5890 EA en un total de 2701 tratamientos (844 y 1857 sin y con DME-b/sd, respectivamente), con una incidencia de 53,9 eventos cada 1000 pacientes/año (IC 95% 51,9-55,9). La misma fue mayor en los ciclos con DME-b/sd (71,1 eventos cada 1000 pacientes/año, IC 95% 70,7-77,5 versus 33,7, IC 95% 31,5-36,1; p<0,001). Las infecciones, particularmente las de la vía aérea superior, fueron los EA más frecuentes en ambos grupos. El 10,9% fue serio y el 1,1% provocó la muerte del paciente. El 18,7% de los ciclos con DME-b/sd fue discontinuado a causa de un EA significativamente mayor a lo reportado en el otro grupo (11,5%; p<0,001). En el análisis ajustado, las DME-b/sd se asociaron a mayor riesgo de presentar al menos un EA (HR 1,82, IC 95% 1,64-1,96). De igual manera, la mayor edad, el mayor tiempo de evolución, el antecedente de enfermedad pulmonar obstructiva crónica, el diagnóstico de lupus eritematoso sistémico y el uso de corticoides se asociaron a mayor riesgo de EA. Conclusiones: la incidencia de EA fue significativamente superior durante los ciclos de tratamientos que incluían DME-b/sd.

Introduction: knowing the efficacy and safety of the drugs currently available for the treatment of rheumatic diseases is very important when making objective and individualized therapeutic decisions in daily medical consultation. Likewise, real-life data extends the knowledge revealed by clinical trials. Objectives: to describe the reported adverse events (AEs), estimate their frequency and identify factors associated to them. Materials and methods: BIOBADASAR data were used, which is a voluntary, prospective follow-up registry of AEs of biological and synthetic treatments in patients with immune-mediated rheumatic diseases. Patients are followed until death, loss of followup, or withdrawal of informed consent. To carry out this analysis, the data collected up to January 31, 2023 was extracted. Results: a total of 6253 patients were included, who contributed with 9533 treatment periods, including 3647 (38.3%) periods without b/ts-DMARDs and 5886 (61.7%) with b/ts-DMARDs. Among the latter, the most used were TNF inhibitors and abatacept. A total of 5890 AEs were reported in a total of 2701 treatments (844 and 1857 without and with b/ts-DMARDs, respectively), with an incidence of 53.9 events per 1000 patients/ year (95% CI 51.9-55.9). It was higher during the periods with b/ts-DMARDs (71.1 events per 1000 patients/year, 95% CI 70.7-77.5 vs 33.7, 95% CI 31.5-36.1, p<0.001). Infections, particularly those of the upper respiratory tract, were the most frequent AEs in both groups. 10.9% were severe and 1.1% were associated with the death of the patient. 18.7% of the periods with b/ts-DMARDs were discontinued due to an AE, significantly higher than that reported in the other group (11.5%; p<0.001). In the adjusted analysis, b/ts-DMARDs were associated with a higher risk of presenting at least one AE (HR 1.82, 95% CI 1.64-1.96). Similarly, older age, longer evolution time, history of chronic obstructive pulmonary disease, diagnosis of systemic lupus erythematosus, and use of corticosteroids were associated with a higher risk of AE. Conclusions: the incidence of AEs was significantly higher during those treatment periods that included DME-b/sd.

GPR55 activation prevents amphetamine-induced conditioned place preference and decrease the amphetamine-stimulated inflammatory response in the ventral hippocampus in male rats.

Inflammatory response in the Central Nervous System (CNS) induced by psychostimulants seems to be a crucial factor in the development and maintenance of drug addiction. The ventral hippocampus (vHp) is part of the reward system involved in substance addiction and expresses abundant G protein-coupled receptor 55 (GPR55). This receptor modulates the inflammatory response in vitro and in vivo, but there is no information regarding its anti-inflammatory effects and its impact on psychostimulant consumption. The aim of the present study was to investigate whether vHp GPR55 activation prevents both the inflammatory response induced by amphetamine (AMPH) in the vHp and the AMPH-induced conditioned place preference (A-CPP). Wistar adult male rats with a bilateral cannula into the vHp or intact males were subjected to A-CPP (5 mg/kg). Upon the completion of A-CPP, the vHp was dissected to evaluate IL-1ß and IL-6 expression through RT-PCR, Western blot and immunofluorescence. Our results reveal that AMPH induces both A-CPP and an increase of IL-1ß and IL-6 in the vHp. The GPR55 agonist lysophosphatidylinositol (LPI, 10 µM) infused into the vHp prevented A-CPP and the AMPH-induced IL-1ß increase. CID 16020046 (CID, 10 µM), a selective GPR55 antagonist, abolished LPI effects. To evaluate the effect of the inflammatory response, lipopolysaccharide (LPS, 5 µg/µl) was infused bilaterally into the vHp during A-CPP acquisition. LPS strengthened A-CPP and increased IL-1ß/IL-6 mRNA and protein levels in the vHp. LPS also increased CD68, Iba1, GFAP and vimentin expression. All LPS-induced effects were blocked by LPI. Our results suggest that GPR55 activation in the vHp prevents A-CPP while decreasing the local neuro-inflammatory response. These findings indicate that vHp GPR55 is a crucial factor in preventing the rewarding effects of AMPH due to its capacity to interfere with proinflammatory responses in the vHp.

Locoregional relapse after sparing mastectomies and immediate reconstruction in women with breast cancer.

INTRODUCTION: In recent years, cultural changes in today's society and improved risk assessment have increased the indication for mastectomies in women with breast cancer. Various studies have confirmed the oncological safety of sparing mastectomies and immediate reconstruction. The objective of this study is to analyze the incidence of locoregional relapses of this procedure and its impact on reconstruction and overall survival. PATIENTS AND METHODS: Prospective study of patients with breast carcinoma who underwent a sparing mastectomy and immediate reconstruction. Locoregional relapses and their treatment and their impact on survival were analyzed. RESULTS: The study group is made up of 271 women with breast carcinoma treated with a skin-sparing mastectomy and immediate reconstruction. The mean follow-up was 7.98 years and during the same 18 locoregional relapses (6.6%) were diagnosed: 72.2% in the mastectomy flap and 27.8% lymph node. There were no significant differences in the pathological characteristics of the primary tumor between patients with and without locoregional relapse, although the percentage of women with hormone-sensitive tumors was higher in the group without relapse. Patients with lymph node relapse had larger tumors (80% T2-T3) and 60% had axillary metastases at diagnosis, compared to 7.7% of women with skin relapse (p = 0.047). All patients operated on for locoregional relapse preserved their reconstruction. The incidence of metastases and deaths was significantly higher in patients with a relapse, causing a non-significant decrease in overall survival. CONCLUSION: Locoregional relapses are a rare event in women with a sparing mastectomy and immediate reconstruction. Most patients with locoregional relapse can preserve their initial reconstruction through local resection of the tumor and adjuvant and / or neoadjuvant therapies.

Evolución clínica del tratamiento empírico versus dirigido de la infección relacionada a catéter de hemodiálisis

RESUMEN Introducción: las infecciones relacionadas a catéteres utilizados en hemodiálisis constituyen una de las causas de morbimortalidad más frecuentes. No se dispone de estudios previos en el Paraguay que demuestren la diferencia entre tratamiento empírico y dirigido de infección relacionada a catéter de hemodiálisis Objetivo: determinar la evolución clínica del tratamiento empírico de la infección relacionada a catéter versus el tratamiento dirigido en pacientes adultos. Material y métodos: se aplicó un diseño observacional, retrospectivo, de corte transversal que incluyó 128 pacientes internados en el Hospital Nacional, Itauguá, Paraguay, durante los años 2020 y 2021. Fueron divididos en grupos de tratamiento dirigido (64 pacientes) y empírico (64 pacientes). Resultados: la edad media fue 52 ± 14 años. El acceso vascular yugular fue el más utilizado (78,91%). Se observó que el transcurso de días entre la colocación de catéter de hemodiálisis hasta su infección fue 16 ± 7,6 días. El crecimiento microbiano predominante en ambos grupos fue de cocos gram positivos (84,37%). S. aureus se aisló en 84,31% del grupo tratamiento dirigido y en 15,68% del grupo con tratamiento empírico. El grupo antibiótico más utilizado en ambos grupos fueron los glucopéptidos (77,34%) y la combinación más utilizada fue ciprofloxacina con vancomicina tanto en el grupo dirigido (37,5%) como en el empírico (31,25%). El desenlace curación de infección se observó en 90,62% en el grupo de tratamiento empírico y en 82,81% en el grupo dirigido. La frecuencia de sepsis fue 17,18% en el grupo empírico y 32,8% en grupo dirigido. La mortalidad fue 9,37% en grupo empírico y 14,06% en grupo dirigido. Conclusión: el germen más prevalente fue S. aureus. La curación de infección relacionada a catéter fue más frecuente en el grupo empírico, la mortalidad y sepsis predominaron en el grupo dirigido.

ABSTRACT Introduction: Infections related to catheters used in hemodialysis are one of the most frequent causes of morbidity and mortality. There are no previous studies in Paraguay that demonstrate the difference between empirical and directed treatment of hemodialysis catheter-related infection. Objective: To determine the clinical course of empirical treatment versus targeted treatment of catheter-related infection in adult patients. Material and methods: An observational, retrospective, cross-sectional design was applied including 128 patients admitted to the Hospítal Nacional of Itauguá, Paraguay, during the years 2020 and 2021. They were divided into directed (64 patients) and empirical (64 patients) treatment groups. Results: The mean age was 52 ± 14 years. The jugular vascular access was the most used (78.91%). It was observed that the time between hemodialysis catheter placement and infection was 16±7.6 days. The predominant microbial growth in both groups was gram-positive cocci (84.37%). S. aureus was isolated in 84.31% of the directed treatment group and in 15.68% of the empirical treatment group. The most used antibiotic group in both groups were glycopeptides (77.34%) and the most used combination was ciprofloxacin with vancomycin, both in the targeted group (37.5%) and in the empirical group (31.25%). The outcome of infection cure was observed in 90.62% in the empirical treatment group and in 82.81% in the directed group. The frequency of sepsis was 17.18% in the empirical group and 32.8% in the directed group. Mortality was 9.37% in the empirical group and 14.06% in the directed group. Conclusion: The most prevalent germ was S. aureus. Cure of catheter-related infection was more frequent in the empiric group, while mortality and sepsis predominated in the directed group.

Complicaciones de la endocarditis infecciosa al momento del diagnóstico y su relación con los gérmenes aislados en pacientes adultos

RESUMEN Introducción: la endocarditis infecciosa es una enfermedad de una variada presentación clínica. Es cada vez más frecuente debido a los cuidados relacionados con la salud. Objetivo: determinar las complicaciones de los pacientes con endocarditis infecciosa bacteriana al momento del diagnóstico y su relación con el agente causal y ofrecer una descripción general de las características demográficas y clínicas presentes en pacientes del Hospital Nacional, Itauguá, Paraguay, en el periodo 2017-2021. Material y métodos: estudio descriptivo, observacional, retrospectivo que incluyo 37 pacientes con el diagnóstico de endocarditis infecciosa con germen aislado. Resultados: la edad media fue 45 ±14 años, la mayoría provenía del área urbana y era del sexo masculino (65%). La comorbilidad más frecuente fue enfermedad renal crónica (50%). Los procedimientos invasivos (catéter venoso central simple) fueron el foco de bacteriemia más frecuente (65,22%). La válvula más comprometida fue la aórtica, la complicación más frecuente fue la insuficiencia cardiaca (70,27%), hubieron 49% de desenlaces fatales. El germen más frecuente y causante de la mayor morbimortalidad fue Staphylococcus aureus (43,24%). Conclusión: la enfermedad renal crónica fue el principal factor de riesgo. Ser portador de catéter venoso simple de hemodiálisis estuvo relacionado al aislamiento del Staphylococcus aureus como agente causal más frecuente. Este germen estuvo relacionado a la alta tasa de complicaciones al momento del ingreso y con el alto porcentaje de desenlaces fatales.

ABSTRACT Introduction: Infective endocarditis is a disease with a varied clinical presentation. It is becoming more frequent due to health-related care. Objective: To determine the complications of patients with bacterial infective endocarditis at the time of diagnosis and their relationship with the causal agent and offer a general description of the demographic and clinical characteristics present in patients of the Hospital Nacional of Itauguá, Paraguay, in the period 2017- 2021. Material and methods: Descriptive, observational, retrospective study that included 37 patients diagnosed with infective endocarditis with isolated germ. Results: The mean age was 45±14 years, the majority came from the urban area and was male (65%). The most frequent comorbidity was chronic kidney disease (50%). Invasive procedures (simple central venous catheter) were the most frequent source of bacteremia (65.22%). The most compromised valve was the aortic, the most frequent complication was heart failure (70.27%) and there was 49% of fatal outcomes. The most frequent germ and cause of the highest morbidity and mortality was Staphylococcus aureus (43.24%). Conclusion: Chronic kidney disease was the main risk factor. Being a carrier of a simple venous hemodialysis catheter was related to the isolation of Staphylococcus aureus as the most frequent causal agent. This germ was related to the high rate of complications at the time of admission and the high percentage of fatal outcomes.

Shoulder and Upper Back Pain: An Unusual Initial Presentation of Rare Stage IV Small Cell Neuroendocrine Cervical Cancer.

While musculoskeletal pain is cited as the primary cause of disability and reason for visiting the emergency department in the United States, secondary etiologies should be considered. In this case report, we are reporting a unique case of a 38-year-old multiparous healthy female who presented to multiple emergency departments with fleeting pain on the shoulders and upper back. She was diagnosed with muscle spasms and joint arthritis and discharged home multiple times. The patient then developed vaginal bleeding, belt-line numbness, and was found to have T6 spinal cord compression. Imaging prompted workup for malignancy, which revealed small cell neuroendocrine cervical cancer (SCNECC) with metastasis to intra-abdominal lymph nodes, bone, and brain. SCNECC is very rare, aggressive, occurs in less than 3% of cervical cancers, and does not have established treatment guidelines. Because it is commonly misdiagnosed and has an overall poor prognosis, SCNECC can be missed if it is not part of the differential.

Inflammatory reactivity to the influenza vaccine is associated with changes in automatic social behavior.

Recent evidence suggests differential patterns of social behavior following an inflammatory challenge, such that increases in inflammation may not uniformly lead to social withdrawal. Indeed, increases in inflammation have been associated with enhanced self-reported motivation to approach a specific close other, and greater neural sensitivity to positive social cues. However, no known studies have examined the association between inflammation in response to an inflammatory challenge and social behavior in humans, nor has past research examined specifically how approach and withdrawal behavior may differ based on whether the target is a close other or stranger. To address this, 31 participants (ages 18-24) received the influenza vaccine to elicit a low-grade inflammatory response. The morning before and approximately 24 h after the vaccine, participants provided a blood sample and completed a computer task assessing automatic (implicit) approach and withdrawal behavior toward a social support figure and strangers. Greater increases in the inflammatory cytokine interleukin-6 (IL-6) in response to the vaccine were associated with an increase in accuracy in avoiding strangers and a decrease in accuracy in approaching them. Increases in IL-6 were also associated with a decrease in reaction time to approach a support figure, but only when controlling for baseline IL-6 levels. There were no associations between change in IL-6 and changes in self-reported motivation to engage in social behavior with either close others, or strangers. Together, these findings reveal that increases in inflammation following the influenza vaccine are associated with automatic social behavior, especially behavior suggesting avoidance of unfamiliar social targets and ease in approaching a support figure. These data add to the growing literature suggesting that the association between inflammation and social behavior includes both social withdrawal and social approach, depending on the specific target.

Prevalence of Epilepsy, Human Cysticercosis, and Porcine Cysticercosis in Western Kenya.

Cysticercosis is the leading cause of acquired epilepsy worldwide and has been shown to be highly prevalent in pig populations in western Kenya. We conducted a community-based door-to-door survey in a region of western Kenya with a high proportion of pig-keeping households. Persons with epilepsy (PWE) were determined using a screening questionnaire followed by a neurologist evaluation. Cysticercosis serum apDia antigen ELISAs and Western blot for LLGP and rT24h antigen were performed on all PWE and 2% of screen-negative patients. All PWE or people with positive apDia underwent contrast-enhanced brain computed tomography (CT). Of a sample of 810 village residents, 660 (81%) were present in the homestead, of whom 648 (98%) participated. Of these, 17 were confirmed to have lifetime epilepsy, an estimated crude prevalence of 2.6%. No humans with (N = 17) or without (N = 12) epilepsy had serological evidence of cysticercosis infection. Fourteen PWE and one individual with borderline positive apDia antigen ELISA underwent brain CT; none had radiographic findings consistent with neurocysticercosis. Nearly 30% of households kept pigs, with 69% always tethered in both wet and dry seasons. More than 8% (6/72) of pigs had palpable lingual cysts; these pigs all originated from homesteads with latrines, one-third of which were free-ranging at least some of the time. Epilepsy prevalence in our study was greater than the national prevalence, but we found no individuals with epilepsy attributable to cysticercosis. Additional studies are required to identify causes of epilepsy, human and porcine cysticercosis, the role of spatial clustering, and protective factors like host-pathogen immunity.

Abstract Preliminary results of a research that seeks to characterize the intervention model of an Intensive Outpatient Program for the treatment of drug and/or alcohol use in pregnant and maternity women of the CRS of the Hospital El Pino, in the commune of San Bernardo, Chile, are presented. The objective is to describe the characteristics of the accompaniment process with a gender approach carried out by the health team working in the program and to consider its transdisciplinary character as keys to improving adherence, reducing dropout rates, favoring therapeutic discharges, promoting autonomy and the exercise of rights. The methodological design corresponds to qualitative research with an emic and intracultural approach, which seeks the point of view within the team. The sample is purposive, and the information was produced through nine participative group interviews with the work teams and an individual semi-structured interview with the head of the program, carrying out a thematic analysis of the experiences shared. The results indicate that the accompaniments from a gender and human rights perspective favor transdisciplinary work, key aspects to reduce equity gaps, and favor access to health for women in vulnerable conditions. Being the occupational therapies from the south are important to enhance these processes.

Biocide effect against SARS-CoV-2 and ESKAPE pathogens of a noncytotoxic silver-copper nanofilm.

Nanometric materials with biocidal properties effective against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) and pathogenic bacteria could be used to modify surfaces, reducing the risk of touching transmission. In this work, we showed that a nanometric layer of bimetallic AgCu can be effectively deposited on polypropylene (PP) fibers. The virucidal properties of the AgCu nanofilm were evaluated by comparing the viral loads remaining on uncoated and coated PP after contact times between 2 and 24 h. Quantification of virion numbers for different initial concentrations indicated a reduction of more than 95% after 2 h of contact. The bactericidal action of the AgCu nanofilm was also confirmed by inoculating uncoated and coated PP with a pool of pathogenic bacteria associated with pneumonia (ESKAPE). Meanwhile, no cytotoxicity was observed for human fibroblasts and keratinocyte cells, indicating that the nanofilm could be in contact with human skin without threat. The deposition of the AgCu nanofilm on the nonwoven component of reusable cloth masks might help to prevent virus and bacterial infection while reducing the pollution burden related to the disposable masks. The possible mechanism of biocide contact action was studied by quantum chemistry calculations that show that the addition of Ag and/or Cu makes the polymeric fiber a better electron acceptor. This can promote the oxidation of the phospholipids present at both the virus and bacterial membranes. The rupture at the membrane exposes and damages the genetic material of the virus. More studies are needed to determine the mechanism of action, but the results reported here indicate that Cu and Ag ions are good allies, which can help protect us from the virus that has caused this disturbing pandemic.

Removal of nutrients from Organic Liquid Agricultural Waste using filamentous algae / Remoção de nutrientes de Resíduos Agrícolas Líquidos Orgânicos utilizando algas filamentosas

Abstract A feasibility analysis of tertiary treatment for Organic Liquid Agricultural Waste is presented using filamentous algae belonging to the genus Cladophora sp. as an alternative to chemical tertiary treatment. The main advantages of tertiary treatments that use biological systems are the low cost investment and the minimal dependence on environmental variables. In this work we demonstrate that filamentous algae reduces the nutrient load of nitrate (circa 75%) and phosphate (circa 86%) from the organic waste effluents coming from dairy farms after nine days of culture, with the added advantage being that after the treatment period, algae removal can be achieved by simple procedures. Currently, the organic wastewater is discarded into fields and local streams. However, the algae can acquire value as a by-product since it has various uses as compost, cellulose, and biogas. A disadvantage of this system is that clean water must be used to achieve enough water transparency to allow algae growth. Even so, the nutrient reduction system of the organic effluents proposed is friendly to the ecosystem, compared to tertiary treatments that use chemicals to precipitate and collect nutrients such as nitrates and phosphates.

Resumo Uma análise de viabilidade do tratamento terciário para Resíduos Agrícola Líquidos Orgânicos é apresentada usando algas filamentosas pertencentes ao gênero Cladophora sp. como alternativa ao tratamento químico terciário. Os tratamentos terciários que utilizam sistemas biológicos têm baixo custo de investimento e a dependência de variáveis ​​ambientais é mínima. Neste trabalho, é demonstrado que essas algas filamentosas reduzem a carga nutricional de nitrato (circa 75%) e fosfato (circa 86%) dos efluentes de resíduos orgânicos provenientes de fazendas de leite em nove dias de cultura e tem a vantagem de que as algas podem ser facilmente coletadas posteriormente. Atualmente, as águas residuais orgânicas são descartadas nos campos e córregos locais. Posteriormente, as algas podem ser consideradas como matéria prima, uma vez que possuem várias utilidades como composto, celulose e biogás. Uma desvantagem desse sistema é que água limpa deve ser usada para obter transparência de água suficiente para permitir o crescimento de algas. Mesmo assim, o sistema de redução de nutrientes dos efluentes orgânicos propostos e amigável ao ecossistema, comparado aos tratamentos terciários que utilizam produtos químicos para precipitar e coletar nutrientes como nitratos e fosfatos.

Characterization of HIV-Associated Neurocognitive Impairment in Middle-Aged and Older Persons With HIV in Lima, Peru.

Background: With widespread use of antiretroviral medications, people living with HIV (PWH) are living longer worldwide, increasing their risk of developing neurocognitive impairment (NCI). The proportion of Peruvians over age 60 is expected to increase to 25% of the population by 2050, including PWH. Therefore, the problem of aging and NCI, especially in the setting of HIV infection, is uniquely pressing. We sought to study the rates of and risk factors associated with NCI among middle-aged and older PWH in Lima, Peru. Materials and Methods: Sociodemographic, medical (infectious and non-infectious), and psychiatric comorbidity and laboratory data were collected. We administered a brief neuropsychological battery evaluating seven cognitive domains affected in HIV-associated NCI and a depression screening. Cognitive test raw scores were converted to T-scores that were demographically adjusted. Descriptive statistics were performed together with regression (unadjusted and adjusted) analyses to determine potential risk factors for NCI among PWH. Results: This was a cross-sectional study in which 144 PWH aged ≥40 years attending a large HIV clinic in Lima, Peru, were recruited from September 2019 to March 2020. Mean age was 51.6 ± 7.7 years, and mean years of education were 14.0 ± 3.1 with 15% females. Median [interquartile range (IQR)] current CD4 and nadir CD4 were 554 (371, 723) and 179 (83, 291), respectively, and 10% currently had AIDS. The prevalence of NCI was 28.5%, and many demonstrated difficulty with attention and working memory (70%). One-quarter of PWH had mild depression or worse on Patient Health Questionnaire 9 (PHQ-9 ≥ 5). In bivariate analyses, neither a depression history nor a higher PHQ-9 score correlated with NCI. No other non-communicable medical or psychiatric comorbidity nor HIV characteristic was predictive of NCI. Having a positive lifetime history of hepatitis B infection, pulmonary tuberculosis, or syphilis increased risk of NCI (PR 1.72; 95% CI 1.04-2.86) in unadjusted analyses, but not in adjusted analyses. Conclusions: NCI among older Peruvians with HIV was found to be highly prevalent with levels consistent with prior reports of HIV-associated NCI worldwide. Common latent HIV-associated co-infections, including latent syphilis, hepatitis B infection, or pulmonary tuberculosis, may increase the risk of NCI among middle-aged and older PWH in Peru.
