Analysis of physical activity in psoriatic arthritis: relationship with clinical and analytical parameters and comorbidity-description of the sedentary patient.

Objective: This study aimed to relate physical activity and a sedentary lifestyle to clinical, biological, functional, and comorbid parameters in a cohort of patients with psoriatic arthritis (PsA). Methods: A cross-sectional study was conducted with 232 PsA patients. Physical activity and sedentary lifestyle were obtained using the International Physical Activity Questionnaire (IPAQ) questionnaire. The demographic, clinical, and biological variables measured were age, time since PsA diagnosis, smoking, type of treatment used, clinical form, presence of enthesitis, dactylitis (present or past), fatigue, tumor necrosis factor (TNF)-alpha, and interleukin 6 (IL-6). Activity and functionality were measured using the Disease Activity Index for Psoriatic Arthritis (DAPSA) and Health Assessment Questionnaire (HAQ) in peripheral forms, while the Ankylosing Spondylitis Disease Activity Score (ASDAS-PCR) and Bath Ankylosing Spondylitis Functional Index (BASFI) were measured in axial forms. Disease impact was assessed using the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire. Alongside comorbidities, obesity, anxiety, depression [Hospital Anxiety and Depression Scale (HADS)], and sleep quality [Insomnia Severity Index (ISI)] were assessed. Results: The mean age was 54.6 (SD: 11.4) years, with 54.3% being male. A total of 25.6% of patients were sedentary. Physical activity and sedentary lifestyle were inversely correlated with fatigue, activity, functionality, and disease impact. Within comorbidities, they correlated with anxiety, depression, and insomnia. In addition, physical activity was inversely correlated with obesity. In linear regression analysis, physical activity was found to be related to body mass index (BMI) with a ß coefficient of -0.1 (p < 0.04; 95%CI: -194.1--4.5), and an R2 value of 0.11. In logistic regression analysis, a sedentary lifestyle was found to be related to pain, with an odds ratio (OR) of 1.5 (p < 0.001; 95%CI:1.1-1.8) and an R2 Nagelkerke value of 0.36. Conclusion: A quarter of the patients were sedentary. Lack of physical activity correlated with worse parameters of clinical activity, functionality, disease impact, and the presence of comorbidities.

What happened to my Index Medicus?

From its first printing in 1879 to when publication ceased in 2004, the Index Medicus had proved invaluable for persons wishing to conduct healthcare-related research. With the loss of this resource and the rapid expansion of alternative, online sources, it is vital that persons understand how to appropriately search for and use this information. The purpose of this review is to outline the information sources available, discuss how to use current search technology to best obtain relevant information while minimizing nonproductive references, and give the author's opinion on the reliability of the various informational sources available. Topics to be discussed will include Medical Subject Headings and PICO searches and sources ranging from the National Library of Medicine and Cochrane Reviews to Wikipedia and other sites, such as associations and commercial interest sites.

Association between gamma glutamyl transpeptidase to HDL-Cholesterol (GGT/HDL-C) ratio and metabolic syndrome resolution after sleeve gastrectomy.

OBJECTIVE: To evaluate the association between GGT/HDL-C ratio and resolution of MetS in adults after sleeve gastrectomy (SG). METHODS: We conducted a retrospective cohort study using secondary data from a Peruvian bariatric center. The study population consisted of adults aged 18 and above who underwent laparoscopic SG and were diagnosed with MetS prior to the surgery. The main outcome measured was MetS resolution 6 months post-surgery and the exposure variable was the GGT/HDL-C ratio. RESULTS: We analyzed 137 patients with a mean age of 38.9 ± 10.9 years; 64.2% were females. The median GGT/HDL-C ratio was 1.1 [0.7 - 1.5], and 83.9% of patients experienced resolution of MetS. Furthermore, both the middle tertile of GGT/HDL-C (aRR: 1.28; 95% CI: 1.04 - 1.58; p = .019) and the lowest tertile (aRR: 1.27; 95% CI: 1.01 - 1.60; p = .038) showed a significant association with the resolution of MetS. CONCLUSION: Eight out of 10 patients undergoing SG experience resolution of MetS within 6 months after surgery. Patients in the middle and lower tertiles of the GGT/HDL-C were more likely to achieve this outcome. Therefore, the GGT/HDL-C ratio should be considered a valuable and efficient biomarker for preoperative assessment of bariatric surgery candidates.

Plasmodium falciparum alters the trophoblastic barrier and stroma villi organization of human placental villi explants.

BACKGROUND: The sequestration of Plasmodium falciparum infected erythrocytes in the placenta, and the resulting inflammatory response affects maternal and child health. Despite existing information, little is known about the direct impact of P. falciparum on the placental barrier formed by trophoblast and villous stroma. This study aimed to assess placental tissue damage caused by P. falciparum in human placental explants (HPEs). METHODS: HPEs from chorionic villi obtained of human term placentas (n = 9) from normal pregnancies were exposed to P. falciparum-infected erythrocytes (IE) for 24 h. HPEs were embedded in paraffin blocks and used to study tissue damage through histopathological and histochemical analysis and apoptosis using TUNEL staining. Culture supernatants were collected to measure cytokine and angiogenic factors and to determine LDH activity as a marker of cytotoxicity. A subset of archived human term placenta paraffin-embedded blocks from pregnant women with malaria were used to confirm ex vivo findings. RESULTS: Plasmodium falciparum-IE significantly damages the trophoblast layer and the villous stroma of the chorionic villi. The increased LDH activity and pathological findings such as syncytial knots, fibrin deposits, infarction, trophoblast detachment, and collagen disorganization supported these findings. The specific damage to the trophoblast and the thickening of the subjacent basal lamina were more pronounced in the ex vivo infection. In contrast, apoptosis was higher in the in vivo infection. This disparity could be attributed to the duration of exposure to the infection, which significantly varied between individuals naturally exposed over time and the 24-h exposure in the ex vivo HPE model. CONCLUSION: Exposure to P. falciparum-IE induces a detachment of the syncytiotrophoblast, disorganization of the stroma villi, and an increase in apoptosis, alterations that may be associated with adverse results such as intrauterine growth restriction and low birth weight.

Tuberculosis in pregnancy and adverse neonatal outcomes in two peruvian hospitals.

Background: According to the World Health Organization, tuberculosis (TB) ranks among the top 10 causes of death worldwide. The significance of TB during pregnancy lies in its symptoms, which can be mistaken for physiological changes associated with pregnancy. This confusion can lead to maternal-perinatal complications. Objective: To evaluate the association between pulmonary TB in pregnancy and adverse neonatal outcomes in two Peruvian hospitals. Methods: This is a retrospective cohort study. The target population consisted of pregnant women with and without pulmonary TB whose deliveries were attended at two public hospitals, located in Lima, Peru. The adverse neonatal outcomes were prematurity, low birth weight (LBW), and being small for gestational age (SGA). Crude and adjusted relative risks (RRa) were calculated with their respective 95% confidence intervals (95%CI). Results: Information from 212 patients was analyzed; 48.1% had TB during pregnancy, and 23.1% had adverse neonatal outcomes (8%, 11.3%, and 12.3% for LBW, prematurity, and SGA, respectively). In the adjusted model, pregnant women with pulmonary TB had a 3.52 times higher risk of having a newborn with at least one of the adverse outcomes than those who were not exposed (aRR, 3.52; 95%CI: 1.93-6.68). Conclusion: Pulmonary TB in pregnancy was jointly and independently associated with adverse neonatal outcomes, including LBW, prematurity, and being SGA.

New non-local mean methods for MRI denoising based on global self-similarity between values.

Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that provides high-resolution 3D images and valuable insights into human tissue conditions. Even at present, the refinement of denoising methods for MRI remains a crucial concern for improving the quality of the images. This study aims to improve the prefiltered rotationally invariant non-local principal component analysis (PRI-NL-PCA) algorithm. We relaxed the original restrictions using particle swarm optimization to determine optimal parameters for the PCA part of the original algorithm. In addition, we adjusted the prefiltered rotationally invariant non-local mean (PRI-NLM) part by traversing the signal intensities of voxels instead of their spatial positions to reduce duplicate calculations and expand the search volume to the whole image when estimating voxels' signal intensities. The new method demonstrated superior denoising performance compared to the original approach. Moreover, in most cases, the new algorithm ran faster. Furthermore, our proposed method can also be applied to process Gaussian noise in natural images and has the potential to enhance other NLM-based denoising algorithms.

The mean annual incidence rate was 3.48 cases/10,000 inhabitants. 18 departments report continuous transmission; Madre de Dios (42.45 cases/10,000 inhabitants) and Cusco (15.78 cases/10,000 inhabitants) report the highest rates. The populations with higher absolute risk are men, adolescents, and young people; residents: from jungle districts; from the quintile with the highest monetary poverty; from the quintile with the highest percentage with at least 1 NBI; and from the quintile with the lowest human development index. Conclusion. Leishmaniasis is widely distributed in Peru, with 56.41% of the population living in districts reporting cases. There are population groups with a higher absolute risk, which can be the target of differentiated prevention and control interventions.

Systemic lupus erythematosus following COVID-19 vaccination. A systematic review of case reports and case series.

OBJECTIVE: Vaccination against SARS-CoV-2 reduced morbidity and mortality rates due to COVID-19 worldwide. However, several adverse effects have been documented and of great interest such as Systemic Lupus Erythematosus (SLE). The aim of the present study was to perform a systematic review of case reports and case series describing the development of SLE following COVID-19 against vaccination. METHODS: Case report and case series studies were included. Systematic reviews, narratives, letters to the editor, correspondence, etc. were excluded. A selective bibliographic search was performed in the PubMed, Scopus, and EMBASE databases. In addition, the Web of Science platform was consulted. The Joanna Brigs Institute (JBI) tool was used to assess the risk of bias and quality of the studies. The Statistical Package for the Social Sciences (SPSS) 23.0 was used for the formal analysis of the descriptive data. RESULTS: 12 studies met the eligibility criteria and reported a total of 16 patients. The mean age was 42.4 ± 18.69 years. A slight predominance of post-vaccination SLE was observed in females (females (n = 9) and males (n = 7). A higher association was found with Pfizer-BioNTech-162b2 vaccine (75%), followed by Sinopharm (12.5%), Moderna (6.25%). and AstraZeneca (6.25%) vaccines. Most cases were associated with the first dose (56.25%), followed by the second dose (37.5%) and only one case associated with the third dose. The number of days elapsed from vaccine administration to the appearance of the first clinical manifestations was between 1 and 30 days. Mainly there was involvement of the musculoskeletal and cutaneous system. All patients responded well to treatment with good evolution and there was no case of death. CONCLUSION: Cases of SLE associated with COVID-19 vaccination against are infrequent. However, clinical monitoring is recommended for persons receiving the SARS-CoV-2 vaccine, mainly those receiving the first dose and the Pfizer-BioNTech-162b2 vaccine.

Assessment of the Integrity and Function of Human Term Placental Explants in Short-Term Culture.

Human placental explants (HPEs) culture has generated significant interest as a valuable in vitro model for studying tissue functions in response to adverse conditions, such as fluctuations in oxygen levels, nutrient availability, exposure to pathogenic microorganisms, and toxic compounds. HPEs offers the advantage of replicating the intricate microenvironment and cell-to-cell communication involved in this critical and transient organ. Although HPEs culture conditions have been extensively discussed, a protocol for assessing the viability and function of HPEs during short-term culture has not been previously outlined. In this study, we have developed a short-term HPEs culture protocol, specifically up to 72 h, and have employed quantitative, semi-quantitative, and qualitative analyses to evaluate tissue viability and function over time. Under our standardized conditions, placental villi explants began to regain their structural properties (the integrity of the trophoblast and villous stroma) and the functionality of the HPEs (production of angiogenic, endocrine, and immunological factors) starting from 48 h of culture. This restoration ensures a suitable environment for several applications. The data presented here can be highly valuable for laboratories aiming to implement an HPEs model, whether in the process of standardization or seeking to enhance and optimize working conditions and timing with placental tissue.

Prognostic performance of neutrophil/lymphocyte ratio and platelet/lymphocyte ratio for mortality in patients with acute stroke.

OBJECTIVE: To evaluate the prognostic performance of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) for mortality in patients with acute stroke treated at a Peruvian hospital. DESIGN: Retrospective cohort study. SETTING: Tertiary care hospital. PATIENTS: Patients aged ≥18 years with a diagnosis of acute stroke and admitted to the hospital from May 2019 to June 2021. INTERVENTIONS: None. MAIN VARIABLES OF INTERESTS: Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and mortality. RESULTS: A total of 165 patients were included. The mean age was 66.1±14.2 years, and 59.4% were male. Only NLR had a performance superior to 0.7 (AUC: 0.75; 95%CI: 0.65-0.85), and its elevated levels were associated with an increased risk of mortality (aRR: 3.66; 95%CI: 1.77-8.85) after adjusting for confounders. CONCLUSION: The neutrophil-to-lymphocyte ratio has an acceptable prognostic performance for mortality in patients with acute stroke. Its use may be considered to stratify patients' risk and to consider timely alternative care and management.

Morphology of the pygidial glands and chemical composition of their secretions in two species of tiger beetles (Carabidae: Cicindelinae).

Pygidial glands are a common feature of all adephagans and their products play an important role in defense against predators. The morphology of the pygidial glands and the chemistry of their secretion were studied for the first time in two species of tiger beetles - Cicindela (Cicindela) sylvicola Dejean, 1822 and Cylindera (Cylindera) germanica (Linnaeus, 1758). The glands were examined by both bright-field microscopy and nonlinear microscopy. All morphological structures of the glands were measured and described in detail. The structures mentioned were compared with those of related taxa. The secretion extracts from the pygidial glands of the investigated taxa contained a total of 24 compounds, which were detected by gas chromatography-mass spectrometry (GC-MS). The secretion mixture of C. (C.) germanica was more complex (21 chemicals) than that of C. (C.) sylvicola (11 ones). Benzaldehyde was present in both secretion samples. Hydrocarbons were the most abundant group of secretory compounds. The purpose of the compounds, their distribution within the subfamily Cicindelinae and their effects on the ecology of the group were discussed.

A 12-month follow-up study of patients with systemic lupus erythematosus after immunization against SARS-CoV-2.

OBJECTIVE: To identify all post-BNT162b2 vaccination (BioNTech and Pfizer) events during the ensuing 12 months in patients with systemic lupus erythematosus (SLE) from the Immuno-Rheumatology Department at Cayetano Heredia Hospital's cohort, Lima, Perú. METHODS: A 12-month follow-up study was conducted from the first dose of immunization with the BNT162b2 vaccine, which was given between May and June 2021, to SLE patients from this cohort. RESULTS: The initial population was constituted by 100 patients (100 patients received the 1st dose, 90 the 2nd dose, and 85 the 3rd dose of this vaccine); 33 patients presented a SLE reactivation (flare), 9% (9/100) post 1st dose, 26.6% (24/90) post 2nd dose, and 16.4% (14/85) post 3rd dose. The most common types of flare were articular (26) and renal (14) with 5/33 (15.1%) requiring hospitalization for flare management. A negative association with flare occurrence was found between the use of hydroxychloroquine RR 0.43 (0.21-0.85) and the opposite was the case for azathioprine RR 2.70 (1.39-5.25). During follow-up, 26 patients developed SARS-CoV-2 infection of whom three required hospitalization, one of whom died. CONCLUSIONS: 33 of 100 SLE patients immunized with BNT162b2 vaccine against SARS-CoV-2, presented SLE flares (47 episodes in total); 5 of these patients required in-hospital management and all fully recovered; 26 patients had SARS-CoV-2 infection; three required hospitalization, one died.

Optimization Method to Predict Optimal Noise Reduction Parameters for the Non-Local Means Algorithm Based on the Scintillator Thickness in Radiography.

The resulting image obtained from an X-ray imaging system depends significantly on the characteristics of the detector. In particular, when an X-ray image is acquired by thinning the detector, a relatively large amount of noise inevitably occurs. In addition, when a thick detector is used to reduce noise in X-ray images, blurring increases and the ability to distinguish target areas deteriorates. In this study, we aimed to derive the optimal X-ray image quality by deriving the optimal noise reduction parameters based on the non-local means (NLM) algorithm. The detectors used were of two thicknesses (96 and 140 µm), and images were acquired based on the IEC 62220-1-1:2015 RQA-5 protocol. The optimal parameters were derived by calculating the edge preservation index and signal-to-noise ratio according to the sigma value of the NLM algorithm. As a result, a sigma value of the optimized NLM algorithm (0.01) was derived, and this algorithm was applied to a relatively thin X-ray detector system to obtain appropriate noise level and spatial resolution data. The no-reference-based blind/referenceless image spatial quality evaluator value, which analyzes the overall image quality, was best when using the proposed method. In conclusion, we propose an optimized NLM algorithm based on a new method that can overcome the noise amplification problem in thin X-ray detector systems and is expected to be applied in various photon imaging fields in the future.

Ethnic disparities in out-of-pocket expense on medicines in Peru: Evidence from a nationwide survey.

Background: Despite improvements in health insurance coverage, out-of-pocket (OOP) health spending remains a public health issue in Peru, and OOP payment has implications for disease treatment in ethnic minorities. We aimed to analyze the ethnic disparities in the OOP payment and estimate the gaps related to observable risk factors in the OOP payment on medicines by ethnic conditions during 2014-2016 in Peru. Study design: cross-sectional study. Methods: We conducted a secondary data analysis using the National Health User Satisfaction Survey. The outcome was the participants' OOP payment in self-reported medications. Ethnic minorities were considered participants who habitually spoke a language other than Spanish at home. Crude and adjusted linear regression models were performed, and the Oaxaca-Blinder decomposition method was used to assess the OPP payment differential by ethnic minority condition, explained by their individual and sociodemographic characteristics. Results: We analyzed 11,346 surveyed, the mean age was 40.78 years, and 57.67 % were women. There was lower OOP payment in medications among ethnic minorities in the adjusted analysis (Beta coefficient [ß]: -0.11; 95 % confidence interval [95%CI]: -0.21 to -0.01; p = 0.043). In the Oaxaca-Blinder decomposition analysis, a gap of 0.19 USD in the OOP payment in medicines among ethnic minorities was found (p < 0.001), and the explained component by the variables measured in this research only represents 40.5 % of the gap (p = 0.001). Conclusion: There was less OOP expenditure on medicines in ethnic minorities. However, the measured variables explain only 40.5 % of these gaps. Therefore, we recommend future research that measures other variables that explain aspects of OOP spending on medicines not identified in this research. Likewise, our findings can be used to establish policies with an intercultural approach that adapt health documents to native languages or are disseminated by trained people from their communities.

Cesarean section prevalence based on prenatal care provider, location, and wealth index: A comparative analysis in peru's healthcare systems.

BACKGROUND: Cesarean section rates are increasing and surpassing WHO guidelines. While sometimes necessary, excessive use poses risks and additional costs to pregnant women and healthcare systems. AIM: To evaluate the prevalence of cesarean section according to healthcare professionals, facility location, and the wealth index of pregnant women in each Peruvian healthcare system. METHODS: A cross-sectional study analyzed 20,870 records of women aged 12 to 49 from the Demographic and Family Health Survey (ENDES). The evaluated healthcare systems were the Ministry of Health, Social Health Insurance, Armed Forces and National Police, and private institutions. FINDINGS: The highest cesarean section prevalence was observed in women receiving prenatal care in private hospitals or clinics (69.13%) and Social Health Insurance hospitals (51.54%). Urban settings, "richest" wealth index, and medical professional involvement increased the probability of cesarean sections. Conversely, the probability of cesarean section was reduced in Ministry of Health facilities when pregnant women belonged to the "poorest" or "poorer" wealth index category and when prenatal care was provided by a midwife in a private facility. CONCLUSION: The prevalence of cesarean sections in Peru during 2021 is 33.75%, warranting evaluation of strategies to regulate their indiscriminate use in each system.

The road from manual to automatic semantic indexing of biomedical literature: a 10 years journey.

Biomedical experts are facing challenges in keeping up with the vast amount of biomedical knowledge published daily. With millions of citations added to databases like MEDLINE/PubMed each year, efficiently accessing relevant information becomes crucial. Traditional term-based searches may lead to irrelevant or missed documents due to homonyms, synonyms, abbreviations, or term mismatch. To address this, semantic search approaches employing predefined concepts with associated synonyms and relations have been used to expand query terms and improve information retrieval. The National Library of Medicine (NLM) plays a significant role in this area, indexing citations in the MEDLINE database with topic descriptors from the Medical Subject Headings (MeSH) thesaurus, enabling advanced semantic search strategies to retrieve relevant citations, despite synonymy, and polysemy of biomedical terms. Over time, advancements in semantic indexing have been made, with Machine Learning facilitating the transition from manual to automatic semantic indexing in the biomedical literature. The paper highlights the journey of this transition, starting with manual semantic indexing and the initial efforts toward automatic indexing. The BioASQ challenge has served as a catalyst in revolutionizing the domain of semantic indexing, further pushing the boundaries of efficient knowledge retrieval in the biomedical field.

Conclusion: Being male, glycosylated hemoglobin values greater than 7% and mean fasting glucose values greater than 130 mg/L were found to increase the likelihood of having a lower extremity amputation.

Impacto de la adicción a redes sociales en la salud mental de los estudiantes de medicina humana, en tiempos de Covid-19 / mpact of addiction to social networks on the mental health of human medicine students, in times of Covid-19

RESUMEN Objetivo: Determinar la asociación de la adicción a redes sociales y las consecuencias en salud mental en estudiantes de medicina humana de la Universidad Ricardo Palma, año 2021. Materiales y métodos: Estudio observacional transversal, participaron 454 estudiantes de medicina humana de primero a quinto año, elegidos por muestreo aleatorio estratificado proporcional al tamaño. El instrumento fue validado, obteniendo un Alpha de Cronbach (α=0,90), los cuestionarios empleados fueron: Adicción a redes sociales (ARS), escala de depresión, ansiedad, estrés (DASS-21) y índice de la calidad del sueño de Pittsburgh (PSQI). A fin de evaluar la asociación entre variables, utilizamos razón de prevalencia (RP) crudo y ajustado, mediante el modelo de regresiones de Poisson con el enlace logarítmico y con intervalo de confianza del 95%. Resultados: El 65,4% eran mujeres, con edad promedio 21,2 años. Se evidenció asociación significativa entre adicción a redes sociales alto y salud mental (RPc: 2,59; IC95%: 1,92-3,50; p: 0,000), así mismo, los niveles alto y medio de adicción a redes sociales con síntomas depresivos, ansiedad, estrés (p: 0,000) y calidad de sueño (p<0,010), respectivamente. El 41%, 49,1% y 9,9% de los estudiantes presentaron adicción a redes sociales bajo, medio y alto respectivamente. Un 57,5% presentaron síntomas depresivos, 56,4% ansiedad, 70,5% estrés y 77,3% mala calidad de sueño. Conclusiones: Encontramos una fuerte asociación entre ARS y salud mental. Por lo cual se recomienda a los universitarios que sean evaluados por especialistas de salud mental para una correcta identificación, evaluación y manejo de los problemas de la ARS.

ABSTRACT Objective: To determine the association of addiction to social networks and the consequences in mental health in human medicine students of the Ricardo Palma University, year 2021. Materials and methods: Cross-sectional observational study, with the participation of 454 human medicine students from first to fifth year, chosen by stratified random sampling proportional to size. The instrument was validated, obtaining a Cronbach's Alpha (α=0.90), the questionnaires used were: Addiction to Social Networks (ARS), Depression, Anxiety, Stress Scale (DASS-21) and Pittsburgh Sleep Quality Index (PSQI). In order to evaluate the association between variables, we used crude and adjusted prevalence ratio (PR), using the Poisson regression model with the logarithmic link and with the 95% confidence interval. Results: 65.4% were women, with an average age of 21.2 years. A significant association was found between high social network addiction and mental health (PRc: 2.59; 95% CI: 1.92-3.50; p: 0.000) and, likewise, between high and medium levels of social network addiction. social and with depression, anxiety, stress (p: 0.000) and sleep quality (p<0.010), respectively. 41%, 49.1% and 9.9% of the students presented low, medium and high addiction to social networks, respectively. 57.5% had depression, 56.4% anxiety, 70.5% stress and 77.3% poor sleep quality. Conclusions: There was a strong association between ARS and mental health. Therefore, it is recommended that university students visit mental health specialists quarterly for proper identification, evaluation, and management of the problems generated by ARS.
