Rate of severe and fatal infections in a cohort of patients with interstitial lung disease associated with rheumatoid arthritis: a multicenter prospective study.

Objective: To describe severe infection, foci of infection, microorganisms, associated factors, and impact on mortality in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD). Patients and methods: The study was based on a multicenter prospective cohort of patients with RA-ILD followed up from 2015 to 2023. The main outcome measures were incident severe infection and fatal infection. We evaluated infectious foci, etiologic agents, vaccination status, variables associated with lung function, and clinical-therapeutic variables in RA. The incidence rate (IR) for infection and mortality was calculated per 100 person-years, and 3 multivariate models were constructed to explore factors associated with infection. Results: We followed up 148 patients with RA-ILD for a median 56.7 months (699.3 person-years). During this period, 142 patients (96%) had at least 1 infection. A total of 368 infectious episodes were recorded, with an IR of 52.6 per 100 person-years. Of the 48 patients who died, 65% did so from infection. Respiratory infections were the most common first infection (74%), infection overall (74%), and fatal infection (80%) and were caused mostly by SARS CoV-2, Streptococcus pneumoniae, Pseudomonas aeruginosa, and influenza A virus. The factors associated with an increased risk of infection and death in patients with RA-ILD were age, inflammatory activity, and therapy with corticosteroids and immunosuppressants. Conclusion: Patients with RA-ILD have a high risk of serious infection, especially respiratory infection. Infection develops early, is recurrent, and is frequently fatal. The presence of associated factors such as advanced age, joint inflammation, and treatment highlight the importance of integrated and preventive medical care.

Severity and impact of digestive impairment perceived by patients with systemic sclerosis: a cross-sectional study.

OBJECTIVES: To describe the severity and impact of gastrointestinal involvement in patients with systemic sclerosis (SSc) and identify associated factors. PATIENTS AND METHODS: Non-controlled cross-sectional study of patients with SSc (2013 American College of Rheumatology/European League Against Rheumatism criteria). The main variables were severity of gastrointestinal involvement according to the University of California, Los Angeles Scleroderma Clinical Trials Consortium Gastrointestinal Tract 2.0 instrument (UCLA SCTC GIT 2.0) and dysphagia according to the Eating Assessment Tool-10 (EAT-10). We evaluated reflux, distension, diarrhoea, faecal soilage, constipation, emotional well-being and social functioning, as well as dysphagia. Clinical and epidemiological data were collected using the Mini Nutritional Assessment Short Form (MNA-SF) and the EuroQol-5D-3L. The degree of skin fibrosis was assessed using the modified Rodnan skin score (mRSS). Multivariate models were constructed to analyse factors associated with gastrointestinal involvement and dysphagia. RESULTS: Of the 75 patients with SSc included, 58.7% had moderate, severe or very severe reflux, 57.4% had constipation according to UCLA SCTC GIT 2.0 and 49.7% had abdominal distension. Gastrointestinal symptoms interfered significantly with social functioning (42.7%) and emotional well-being (40.0%). Dysphagia (EAT-10≥3) was recorded in 52% of patients, and according to MNA-SF poor nutrition in 30.7%, and clear malnutrition requiring a nutritional intervention in 5.3%. Multivariate adjustment revealed an association between severity of gastrointestinal symptoms according to the mRSS (ß=0.249; p=0.002) and Visual Analogue Scale 3-Level EuroQol-5D (VAS-EQ-5D-3L) (ß=-0.302; p=0.001), whereas presence of dysphagia was associated with the mRSS (OR=2.794; p=0.015), VAS-EQ-5D-3L (OR=0.950; p=0.005) and malnutrition (MNA-SF≤7; OR=3.920; p=0.041). CONCLUSIONS: Patients with SSc frequently present severe gastrointestinal symptoms. These are associated with poor quality of life, more severe skin involvement and malnutrition.

Effects of Dry Needling on Active Myofascial Trigger Points and Pain Intensity in Tension-Type Headache: A Randomized Controlled Study.

Tension-type headache is the most prevalent type of headache and is commonly associated with myofascial pain syndrome and the presence of active myofascial trigger points. This randomized controlled trial aimed to assess the impact of dry needling on the total number of active trigger points, pain intensity, and perceived clinical change in tension-type headache subjects. Thirty-two subjects were randomly assigned to the control and dry needling groups. The presence of active trigger points in 15 head and neck muscles, the headache intensity, and the perceived clinical change were evaluated. A single dry needling technique was administered at each active trigger point across three sessions. Significant differences were observed in the post-treatment measures favouring the dry needling group, including reductions in the headache intensity scores (p = 0.034) and the total number of active trigger points (p = 0.039). Moreover, significant differences in the perception of clinical change were found between the control and treatment groups (p = 0.000). Dry needling demonstrated positive effects in reducing the number of active trigger points and improving the short-term headache intensity in tension-type headache patients. A single dry needling session applied in the cranio-cervical area resulted in a self-perceived improvement compared to the control subjects.

OriPlex: Origami-enabled multiplexed detection of respiratory pathogens.

Origami biosensors leverage paper foldability to develop total analysis systems integrated in a single piece of paper. This capability can also be utilized to incorporate additional features that would be difficult to achieve with rigid substrates. In this article, we report a new design for 3D origami biosensors called OriPlex, which leverages the foldability of filter paper for the multiplexed detection of bacterial pathogens. OriPlex immunosensors detect pathogens by folding nanoparticle reservoirs containing different types of nanoprobes. This releases antibody-coated nanoparticles in a central channel where targets are captured through physical interactions. The OriPlex concept was demonstrated by detecting the respiratory pathogens Pseudomonas aeruginosa (PA) and Klebsiella pneumoniae (KP) with a limit of detection of 3.4·103 cfu mL-1 and 1.4·102 cfu mL-1, respectively, and with a turn-around time of 25 min. Remarkably, the OriPlex biosensors allowed the multiplexed detection of both pathogens spiked into real bronchial aspirate (BAS) samples at a concentration of 105 cfu mL-1 (clinical infection threshold), thus demonstrating their suitability for diagnosing lower tract respiratory infections. The results shown here pave the way for implementing OriPlex biosensors as a screening test for detecting superbugs requiring personalized antibiotics in suspected cases of nosocomial pneumonia.

Dietary and Smoking Acrylamide and Prostate Cancer Risk: CAPLIFE Study.

Acrylamide is a probable carcinogen. Its main sources are the diet and tobacco. The association between acrylamide intake from the diet and tobacco and prostate cancer (PCa) has not been previously evaluated. We aimed to evaluate the relationship between dietary acrylamide intake and exposure to acrylamide through cigarettes and PCa risk. A population-based case-control (CAPLIFE) study was conducted, including 428 incident PCa cases and 393 controls. Smoking and dietary information, with a validated food frequency questionnaire, was collected. We calculated the amount of acrylamide from both sources, and tertiles (Ts) were created. Multivariable logistic regression and restricted cubic spline models were applied to assess the association between exposure to acrylamide and PCa risk. The median was similar for acrylamide in both dietary and smoking acrylamide among PCa cases and controls. No association was observed between dietary acrylamide intake and overall PCa risk (adjusted ORT3vsT1 = 0.90 (95% CI 0.59, 1.37)). A risk trend was observed for acrylamide exposure from cigarette smoking (p-trend = 0.032), with the highest odds in those subjects with the high exposure to acrylamide through cigarettes (adjusted ORT3vsT1 = 1.67 (95% CI 0.92, 3.04)). The restricted cubic splines suggested a linear relationship. In conclusion, acrylamide from smoking could be positively associated with PCa risk, but no association was observed for dietary acrylamide.

Effects of the WHO Labour Care Guide on cesarean section in India: a pragmatic, stepped-wedge, cluster-randomized pilot trial.

Cesarean section rates worldwide are rising, driven by medically unnecessary cesarean use. The new World Health Organization Labour Care Guide (LCG) aims to improve the quality of care for women during labor and childbirth. Using the LCG might reduce overuse of cesarean; however, its effects have not been evaluated in randomized trials. We conducted a stepped-wedge, cluster-randomized pilot trial in four hospitals in India to evaluate the implementation of an LCG strategy intervention, compared with routine care. We performed this trial to pilot the intervention and obtain preliminary effectiveness data, informing future research. Eligible clusters were four hospitals with >4,000 births annually and cesarean rates ≥30%. Eligible women were those giving birth at ≥20 weeks' gestation. One hospital transitioned to intervention every 2 months, according to a random sequence. The primary outcome was the cesarean rate among women in Robson Group 1 (that is, those who were nulliparous and gave birth to a singleton, term pregnancy in cephalic presentation and in spontaneous labor). A total of 26,331 participants gave birth. A 5.5% crude absolute reduction in the primary outcome was observed (45.2% versus 39.7%; relative risk 0.85, 95% confidence interval 0.54-1.33). Maternal process-of-care outcomes were not significantly different, though labor augmentation with oxytocin was 18.0% lower with the LCG strategy. No differences were observed for other health outcomes or women's birth experiences. These findings can guide future definitive effectiveness trials, particularly in settings where urgent reversal of rising cesarean section rates is needed.

Introducción: En los últimos años ha aumentado el número de suicidios en nuestro país con 4003 suicidios en 2021 (el mayor número desde que existen datos), representando también la 1ª causa de muerte externa. A su vez un 77% de las personas que se suicidan tuvieron contacto con algún profesional de atención primaria en el año previo y un 45% el mes previo al suicidio. Material y método: Se empleó un formulario autoadministrado de Google para recoger información acerca del conocimiento de la conducta e ideación suicida, los factores de riesgo y las acciones que se llevan a cabo ante esta situación en Atención Primaria por parte de los profesionales de Enfermería y Medicina. Resultados: A través de la encuesta autoadministrada, se concluyó que casi la totalidad de los participantes están de acuerdo en la relevancia del aumento del número de suicidios en 2022 en España. Más del 50% de la muestra afirma tener un conocimiento escaso o ningún conocimiento acerca de la conducta de riesgo suicida, su detección y abordaje desde Atención Primaria. Además, más del 75% indica no haber recibido formación sobre la prevención de la ideación suicida, considerando necesaria una preparación específica para el adecuado abordaje en la prevención y atención del riesgo de suicidio. Conclusiones: La presente investigación identifica la necesidad de una mayor formación de los profesionales de Atención Primaria en el área de salud estudiada, para realizar un correcto abordaje del paciente suicida.

Caso clínico: “Nadie lo hará por mí” / [Clinical case: “No one will do it for me”]

La adherencia terapéutica, es un hecho variante y complejo ya que son diversos los factores que influyen en él. En los países desarrollados la adherencia terapéutica de los pacientes que padecen enfermedades crónicas es del 50%, requiriendo acciones de prevención y promoción de la salud, que se ven intensificadas cuando la falta de adherencia terapéutica está unida al abuso de sustancias y la dependencia de alcohol. El señor D.R. es un paciente varón de 69 años con paresia crural izquierda, trastorno de la marcha, dependencia para las ABVD y AIVD, HTA, ateromatosis carotidea, mala adherencia terapéutica, abuso de alcohol, sobrepeso e hipercolesterolemia, que ingresa en el hospital en el servicio de Neurología tras sufrir un ictus isquémico. Durante este ingreso, se distingue el progreso en el nivel de implicación y compromiso del paciente con su propia salud. A través de la taxonomía NANDA-I, NOC y NIC, se llevó a cabo un plan de cuidados, aplicando un lenguaje estandarizado y con intervenciones basadas en la evidencia científica. (AU)

Efecto de un multivitamínico sobre la resistencia a la insulina, inflamación y estrés oxidante en un modelo de obesidad inducida en ratas Wistar / Effect of a multivitamin on insulin resistance, inflammation, and oxidative stress in a Wistar rat model of induced obesity

Introducción: la acumulación excesiva de tejido adiposo se acompaña de alteraciones en el estado inflamatorio y aumento del estrés oxidativo, variables que se asocian con la resistencia a la insulina e incremento en los niveles de glucosa e insulina. las vitaminas y minerales refuerzan la capacidad antioxidante e inflamatoria, por lo que planteamos que podrían coadyuvar en el control de resistencia a la insulina y en el metabolismo de la glucosa y lípidos en un modelo de obesidad en rata. Objetivo: analizar el efecto de un suplemento multivitamínico sobre marcadores de resistencia a la insulina, inflamación y estrés oxidativo en ratas obesas con dieta de cafetería. Métodos: se dividieron aleatoriamente 35 ratas macho Wistar de 28 días de edad en cuatro grupos: 1, control dieta estándar; 2, dieta estándar más multivitamínico; 3, obesas con dieta de cafetería; y 4, obesas con dieta de cafetería más multivitamínico. Después de los tratamientos se analizaron los niveles de glucosa, HbA1c, insulina, TNF-α, IL-6, estrés oxidativo y perfil de lípidos por métodos colorimétricos, así como el porcentaje de tejido adiposo y los índices Homeostasis Model Assessment (HOMA) y Quantitative Insulin Sensitivity Check Index (QUICKI). Resultados: el suplemento multivitamínico disminuyó significativamente el tejido adiposo visceral, el índice HOMA, la glucosa, la HbA1c, el estrés oxidante y los marcadores inflamatorios en el grupo obeso más multivitamínico, en comparación con el grupo obeso con dieta de cafetería y el grupo control con dieta estándar. Sin embargo, en el grupo al que se le administró solo el multivitamínico sin dieta de cafetería aumentaron sus niveles de tejido adiposo total, glucosa y estrés oxidativo, así como el índice QUICKI con relación al grupo control con dieta estándar.

Introduction: excessive accumulation of adipose tissue is accompanied by alterations in the inflammatory state and increased oxidative stress, and these variables are associated with insulin resistance and increased glucose and insulin levels. On the other hand, vitamins and minerals reinforce the antioxidant and inflammatory capacity, for this reasons we propose that they could contribute to the control of insulin resistance, glucose and lipid metabolism in a rat model of obesity. Objective: to analyze the effect of a multivitamin supplement on markers of insulin resistance, inflammation, and oxidative stress in obese rats on a cafeteria diet. Methods: thirty-five 28-day-old male Wistar rats were randomly divided into four groups: 1, standard diet control; 2, standard diet plus multivitamin; 3, obese on a cafeteria diet; and 4, obese on a cafeteria diet plus multivitamin. After the treatments, glucose levels, HbA1c, insulin, TNF-α, IL-6, oxidative stress and lipid profile were analyzed by colorimetric methods, as well as the percentage of adipose tissue, Homeostasis Model Assessment (HOMA) index y Quantitative Insulin Sensitivity Check Index (QUICKI). Results: multivitamin supplementation significantly decreased visceral adipose tissue, HOMA index, glucose, HbA1c, oxidant stress, and inflammatory markers in the obese plus multivitamin rat group, compared with the obese cafeteria diet rat group and the standard diet rat control group. However, the group that was administered only the multivitamin without the cafeteria diet had increased levels of total adipose tissue, glucose, and oxidative stress, as well as the QUICKI index relative to the control group with the standard diet.

Interstitial Lung Disease Is Associated with Sleep Disorders in Rheumatoid Arthritis Patients.

OBJECTIVE: To evaluate sleep disorders and associated factors in patients with rheumatoid-arthritis-associated interstitial lung disease (RA-ILD). METHODS: We performed an observational study of 35 patients with RA-ILD (cases) and 35 age- and sex-matched RA patients without ILD (controls). We evaluated sleep disorders (Oviedo Sleep Questionnaire), positive psychological factors (resilience using the Wagnild and Young Resilience Scale, emotional intelligence using the 24-item Trait Meta-Mood Scale), anxiety and depression (Hospital Anxiety and Depression Scale), quality of life (36-item short-form survey), and fatigue (Functional Assessment of Chronic Illness Therapy Questionnaire). Other variables studied included the Charlson Comorbidity Index (CCI) and RA activity according to the DAS28-ESR. RESULTS: Compared to the controls, the cases were characterized by poorer sleep quality with a higher prevalence of insomnia (42% vs. 20%; p = 0.039), greater severity of insomnia (p = 0.001), and lower sleep satisfaction (p = 0.033). They also had poorer resilience and emotional recovery and more severe anxiety and depression. A diagnosis of ILD was the only factor independently associated with the three dimensions of sleep quality. The predictors of poorer sleep satisfaction in patients with RA-ILD were age (ß = -0.379), DAS28-ESR (ß = -0.331), and usual interstitial pneumonia pattern (ß = -0.438). The predictors of insomnia were DAS28-ESR (ß = 0.294), resilience (ß = -0.352), and CCI (ß = 0.377). CONCLUSIONS: RA-ILD is associated with significant sleep disorders. RA-ILD seems to be an independent risk factor for sleep alterations, with a greater impact on insomnia. Age, disease activity, and comorbidity also play a role in sleep disorders in patients with RA-ILD.

Sociodemographic Barriers to Physical Activity and Healthy Diet Through Social Networks in Mexican Breast Cancer Survivors.

Introduction Female breast cancer (BC) survivors are affected by poor eating habits and physical inactivity due to certain environmental, physical, and social barriers to healthy lifestyles. This study aimed to identify the sociodemographic, physical, and economic barriers hindering the adoption of physical activity (PA) and a healthy diet, as well as providing insights into how BC survivors cope with these barriers using social networks. Methods A cross-sectional mixed-methods study was conducted, with a self-administered questionnaire and open-ended questions to determine the barriers to PA and healthy eating, while in the second phase, an interpretive qualitative study was carried out with semi-structured interviews. Descriptive statistics, odds ratios (ORs), correspondence analysis, and multivariate analysis were used to estimate the association between moderate to vigorous PA and fruit and vegetable consumption and BC covariates. Results During the COVID-19 lockdown, 150 Mexican BC survivors were studied. The multivariate analysis showed that age (OR = 2.7, 95% CI: 1.0 to 7.03), socioeconomic level (OR = 3.2, 95% CI: 1.3 to 8.2), and overweight (OR = 3.6, 95% CI: 1.5 to 9.7) were significantly associated with low schooling. BC diagnosis of less than three years and age > 40 years were associated with lack of exercise. Survivors individually addressed the challenges associated with BC without the support of specialists. As a result, they sought information on social networks. Conclusions Regarding BC survivors, age > 40 years, low socioeconomic status, and being overweight were important gaps to PA and a healthy diet. In the testimonials, the primary obstacle to engaging in PA was lack of time, while the high cost of food was the most frequently cited reason for not following a healthy diet. Many of the individuals maintained a poor diet with a low intake of fruits and vegetables. Thus, appropriate information must be provided using technologies to develop skills to deal with BC.

Impacto de la fracción de eyección del ventrículo izquierdo en el consumo de recursos, los costes y el pronóstico en pacientes con insuficiencia cardiaca / Differences in clinical outcomes, health care resource utilization and costs in heart failure patients according to left ventricular ejection fraction

Introducción y objetivos: No se conoce bien el impacto de la fracción de eyección del ventrículo izquierdo (FEVI) en el coste y la utilización de recursos sanitarios (URS) en la insuficiencia cardiaca (IC). El objetivo de nuestro trabajo es comparar el consumo de costes, la URS y el pronóstico según grupos de FEVI. Métodos: Estudio observacional retrospectivo que incluyó a todos los pacientes con diagnóstico principal de IC en urgencias o en una hospitalización en un centro terciario español durante 2018. Se excluyó la IC de nuevo diagnóstico. Se compararon los resultados clínicos, los costes y la URS según la FEVI (reducida [IC-FEr], ligeramente reducida [IC-FElr] y conservada [IC-FEc]) a 1 año. Resultados: De 1.287 pacientes con diagnóstico de IC en urgencias, 365 (28,4%) fueron dados de alta (grupo de urgencias [GU]) y 919 (71,4%), hospitalizados (GH). En total, 190 pacientes (14,7%) tenían IC-FEr; 146 (11,4%), IC-FElr y 951 (73,9%), IC-FEc. La media de edad fue 80,1±10,7 años, y el 57,1% eran mujeres. La mediana [intervalo intercuartílico] del coste por paciente-año fue de 1.889 [259-6.269] euros en el GU y 5.008 [2.747-9.589] euros en el GH (p <0,001). Los pacientes con IC-FEr del GU sufrieron más hospitalizaciones. El coste de la IC-FEr por paciente-año fue superior en ambos grupos: en el GU, 4.763 [2.076-17.155] euros con IC-FEr frente a 3.900 [590-8.013] euros con IC-FElr frente a 3.812 [259-5.486] euros con IC-FEc; en el GH, 6.321 [3.335-796] frente a 6.170 [3.189-10.484] frente a 4.636 [2.609-8.977] euros respectivamente; todos, p <0,001). Esta diferencia se debió a que los pacientes con IC-FEr ingresaron con mayor frecuencia en unidades de cuidados críticos y recibieron más pruebas diagnóstico-terapéuticas. Conclusiones: La FEVI influye significativamente en los costes y URS en la IC. Los pacientes con IC-FEr, especialmente los hospitalizados, concentran un mayor coste que aquellos con IC-FEc.(AU)

Introduction and objectives: The impact of left ventricular ejection fraction (LVEF) on health care resource utilization (HCRU) and cost in heart failure (HF) patients is not well known. We aimed to compare outcomes, HCRUs and costs according to LVEF groups. Methods: Retrospective, observational study of all patients with an emergency department (ED) visit or admission to a tertiary hospital in Spain 2018 with a primary HF diagnosis. We excluded patients with newly diagnosed heart failure. One-year clinical outcomes, costs and HCRUs were compared according to LVEF (reduced [HFrEF], mildly reduced [HFmrEF], and preserved [HFpEF]). Results: Among 1287 patients with a primary diagnosis of HF in the ED, 365 (28.4%) were discharged to home (ED group), and 919 (71.4%) were hospitalized (hospital group [HG]). In total, 190 patients (14.7%) had HFrEF, 146 (11.4%) HFmrEF, and 951 (73.9%) HFpEF. The mean age was 80.1±10.7 years; 57.1% were female. The median [interquartile range] of costs per patient/y was €1889 [259-6269] in the ED group and €5008 [2747-9589] in the HG (P <.001). Hospitalization rates were higher in patients with HFrEF in the ED group. The median costs of HFrEF per patient/y were higher in patients in both groups: €4763 [2076-17 155] vs €3900 [590-8013] for HFmrEF vs €3812 [259-5486] for HFpEF in the ED group, and €6321 [3335-796] vs €6170 [3189-10484] vs €4636 [2609-8977], respectively, in the hospital group (all P <.001). This difference was driven by the more frequent admission to intensive care units, and greater use of diagnostic and therapeutic tests among HFrEF patients. Conclusions: In HF, LVEF significantly impacts costs and HCRU. Costs were higher in patients with HFrEF, especially those requiring hospitalization, than in those with HFpEF.(AU)

Red Blood Cell Transfusion after Postpartum Hemorrhage: Clinical Variables Associated with Lack of Postpartum Hemorrhage Etiology Identification.

Postpartum hemorrhage (PPH) remains a significant obstetric emergency worldwide and a leading cause of maternal death. However, it is commonly underreported, which can represent a major concern for maternal morbidity and mortality. This retrospective case series study analyzed patients with red blood cell transfusion (RBCt) in the postpartum period over a four-year interval at a specific center. A total of 18,674 patients delivered between January 2018 and December 2021. Patients with postpartum RBCt were classified into two groups: those with identified PPH (i-PPH) and those without (non-i-PPH). Clinical variables, delivery details, blood loss data, and treatment information were collected. Statistical analysis involved a comparison of variables between the i-PPH and non-i-PPH groups. Univariate and multivariate analyses were performed, aiming to identify significant associations between the clinical variables and a lack of PPH identification. The incidence of RBCt was 1.26% (236 cases). Patients receiving RBCt had higher rates of cesarean delivery, twin pregnancy, labor induction, and previous cesarean section. Among patients with postpartum RBCt, 34.3% lacked an identified PPH. The rarity of postpartum RBCt contrasts with the increasing rates of PPH, highlighting the importance of diagnosing PPH and postpartum anemia. A strategy of systematic quantification of blood loss during delivery could help detect PPH and anemia before adverse consequences occur.

Effects of a Therapeutic Exercise Protocol for Patients with Chronic Non-Specific Back Pain in Primary Health Care: A Single-Group Retrospective Cohort Study.

BACKGROUND: Back pain is highly prevalent; in Spain, it produces a very high economic cost and the scientific evidence supporting treatments shows low to moderate evidence for exercise. Therefore, the aim of this study was to assess the effectiveness of a therapeutic group exercise protocol in reducing pain intensity and disability in patients with back pain in primary health care setting. METHODS: A total sample of 149 patients who suffered from chronic non-specific back pain was selected. Patients received a therapeutic exercise protocol, including auto-mobilization exercises for the neck and lumbar regions, as well as core stabilization exercises. Pain intensity and disability were evaluated before and after the therapeutic exercise protocol. RESULTS: Statistically significant differences (p < 0.05) were shown in pain intensity and disability for patients with non-specific neck and low-back pain, with an effect size from moderate to large. CONCLUSIONS: A therapeutic exercise protocol may provide beneficial effects upon disability and pain intensity in patients with chronic non-specific back pain, including neck and low-back pain conditions In addition, It could be considered for inclusion as a back-pain-approach program in primary healthcare.

Use of silicone wristbands to measure firefighters' exposures to polycyclic aromatic hydrocarbons (PAHs) during live fire training.

Firefighters experience exposures to carcinogenic and mutagenic substances, including polycyclic aromatic hydrocarbons (PAHs). Silicone wristbands (SWBs) have been used as passive samplers to assess firefighters' exposures over the course of a shift but their utility in measuring short term exposures, source of exposure, and correlations with other measurements of exposure have not yet been investigated. In this study, SWBs were used to measure the concentrations of 16 priority PAHs inside and outside of firefighters' personal protective equipment (PPE) while firefighting. SWBs were placed on the wrist and jacket of 20 firefighters conducting live fire training. Correlations were made with matching data from a sister project that measured urinary concentrations of PAH metabolites and PAH concentrations from personal air samples from the same participants. Naphthalene, acenaphthylene and phenanthrene had the highest geometric mean concentrations in both jacket and wrist SWB, with 1040, 320, 180 ng/g SWB for jacket and 55.0, 4.9, and 6.0 ng/g SWB for wrist, respectively. Ratios of concentrations between the jacket and wrist SWBs were calculated as worker protection factors (WPFs) and averaged 40.1 for total PAHs and ranged from 2.8 to 214 for individual PAHs, similar to previous studies. Several significant correlations were observed between PAHs in jacket SWBs and air samples (e.g., total and low molecular weight PAHs, r = 0.55 and 0.59, p < 0.05, respectively). A few correlations were found between PAHs from SWBs worn on the wrist and jacket, and urinary concentrations of PAH metabolites and PAH concentrations in air samples. The ability of the SWBs to accurately capture exposures to various PAHs was likely influenced by short sampling time, high temperatures, and high turbulence. Future work should further examine the limitations of SWBs for PAH exposures in firefighting, and other extreme environments.

Short text classification approach to identify child sexual exploitation material.

Producing or sharing Child Sexual Exploitation Material (CSEM) is a severe crime that Law Enforcement Agencies (LEAs) fight daily. When the LEA seizes a computer from a potential producer or consumer of the CSEM, it analyzes the storage devices of the suspect looking for evidence. Manual inspection of CSEM is time-consuming given the limited time available for Spanish police to use a search warrant. Our approach to speeding up the identification of CSEM-related files is to analyze only the file names and their absolute paths rather than their content. The main challenge lies in handling short and sparse texts that are deliberately distorted by file owners using obfuscated words and user-defined naming patterns. We present two approaches to CSEM identification. The first employs two independent classifiers, one for the file name and the other for the file path, and their outputs are then combined. Conversely, the second approach uses only the file name classifier to iterate over an absolute path. Both operate at the character n-gram level, whereas novel binary and orthographic features are presented to enrich the text representation. We benchmarked six classification models based on machine learning and convolutional neural networks. The proposed classifier has an F1 score of 0.988, which can be a promising tool for LEAs.

Workshop for Basic Gynaecological Examinations: Improving Medical Student Learning through Clinical Simulation.

INTRODUCTION: This study was designed to evaluate whether the Workshop on Basic Principles for Clinical Gynaecological Exploration, offered to medical students, improves theoretical-practical knowledge, safety, confidence, global satisfaction and the achievement of the proposed objectives in the area of gynaecological clinical examinations. MATERIALS AND METHODS: This was a quasi-experimental pre-post-learning study carried out at the Gynaecology and Obstetrics department of Gregorio Marañón Hospital in Madrid (Spain). The volunteer participants were 4th-year students earning a degree in Medicine during the 2020-2021 and 2021-2022 academic years. The study period was divided into the following stages: pre-workshop, intra-workshop and 2 weeks post-workshop. In the pre-workshop stage, students completed a brief online course to prepare for the workshop. The effectiveness of the workshop was evaluated through multiple-choice tests and self-administered questionnaires to assess self-assurance, self-confidence, self-satisfaction and the achievement of the objectives. RESULTS: Of the 277 students invited in both academic years, 256 attended the workshop (92.4%), with a total participation in the different stages of the study greater than 70%. A total of 82.5% of the students in the 2020-2021 academic year and 80.6% of students in the 2021-2022 academic year did not have any type of experience performing gynaecological clinical examinations. Between the pre-workshop and 2 weeks post-workshop stages, there was significant improvement in theoretical-practical knowledge (improvement mean = 1.38 and 1.21 in 2020-2021 and 2021-2022 academic years, respectively). The security and confidence of the students prior to the workshop were low (average scores less than 5 points) in both academic years. However, post-workshop scores for satisfaction and the achievement of objectives were high in the two academic years; all the values approached or exceeded 8 points. CONCLUSIONS: Our students, after outstanding participation, evaluated the BPCGE, and improved their theoretical and practical knowledge, as well as their skills in a gynaecological clinical examination. Moreover, in their view, after the workshop, they felt very satisfied, far outreaching the proposed aims. In addition, excellent results were maintained over time, year after year.

Prevalence of Malnutrition and Associated Factors in Older Patients with Rheumatoid Arthritis: A Cross-Sectional Study.

OBJECTIVE: To describe the frequency of malnutrition in older patients with rheumatoid arthritis (RA) and investigate associated risk factors. METHODS: This multicenter, cross-sectional study included participants aged ≥65 years who met the 2010 ACR/EULAR criteria for RA. Nutritional status was assessed using the Mini Nutritional Assessment Short Form (MNA-SF) and based on variables, such as albumin level, the Geriatric Nutritional Risk Index (GNRI), and vitamin D. Data were also collected on epidemiological variables, inflammatory disease activity, quality of life, physical function, and frailty. Multivariate models were used to study factors associated with nutritional status. RESULTS: The study population comprised 76 RA patients aged ≥65 years, of whom 68.4% had a normal nutritional status, and 31.5% had an impaired nutritional status: 28.9% were at risk of malnutrition, and 2.6% were malnourished. Additionally, 10% had albumin levels <3.8 g/L. Patients with impaired nutritional status had poorer quality of life and physical function. The factors associated with compromised nutritional status (OR [95% CI]) were age (1.0 [1.0-1.1]; p = 0.035), DAS28-ESR (1.8 [1.0-3.2]; p = 0.024), and EuroQoL-5D-5L (0.9 [0.9-0.9]; p = 0.040). Furthermore, the GNRI was associated with the MNA score (0.06 [0.0-0.1]; p = 0.014). CONCLUSIONS: Approximately one-third of older patients with RA have impaired nutritional status. Older age, higher inflammatory disease activity, and decreased quality of life are associated with impaired nutritional status. The MNA and GNRI are valuable tools for assessing the nutritional status of patients with RA.

The duration of intervals on the oral cancer care pathway and implications for survival: a systematic review and meta-analysis.

Introduction: Previous studies measuring intervals on the oral cancer care pathway have been heterogenous, showing mixed results with regard to patient outcomes. The aims of this research were (1) to calculate pooled meta-analytic estimates for the duration of the patient, diagnostic and treatment intervals in oral cancer, considering the income level of the country, and (2) to review the evidence on the relationship of these three intervals with tumor stage at diagnosis and survival. Materials and methods: We conducted a systematic review with meta-analysis following PRISMA 2020 guidelines (pre-registered protocol CRD42020200752). Following the Aarhus statement, studies were eligible if they reported data on the length of the patient (first symptom to first presentation to a healthcare professional), diagnostic (first presentation to diagnosis), or treatment (diagnosis to start of treatment) intervals in adult patients diagnosed with primary oral cancer. The risk of bias was assessed with the Aarhus checklist. Results: Twenty-eight studies reporting on 30,845 patients met the inclusion criteria. The pooled median duration of the patient interval was 47 days (95% CI = 31-73), k = 18, of the diagnosis interval 35 days (95% CI = 21-38), k = 11, and of the treatment interval 30 days (95% CI = 23-53), k = 19. In lower-income countries, the patient and treatment intervals were significantly longer, and longer patient intervals were related to later stage at diagnosis. In studies with a lower risk of bias from high-income countries, longer treatment intervals were associated with lower survival rates. Conclusion: Interval duration on the oral cancer care pathway is influenced by the socio-economic context and may have implications for patient outcomes.
