Relationship between physical function and sarcopenia in the older adults from Amazonas: A cross-sectional study.

Physical functioning refers to the ability to perform daily living activities, namely basic activities, instrumental, and advanced activities. Poorer performance in these areas may indicate the potential presence of sarcopenia. To analyze the differences in physical function between older people with and without sarcopenia and to investigate the associations between physical function tests and sarcopenia. A cross-sectional study based on data from older people from the Northern region of Brazil in the year 2018 was conducted. Study participants included 312 older people aged ≥ 60 years (64.1% female). Sarcopenia was defined using the updated criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). Physical functioning was measured using functional physical fitness tests (30-second chair stand test, chair sit-and-reach test, 8-foot Up-and-Go Test, 6-minute walk test, 4-meter gait speed, and the Fullerton Advanced Balance Scale). Confirmed sarcopenia was detected in 29.2% of participants, but no participant had severe sarcopenia. Most physical function parameters in the crude analysis were associated with confirmed sarcopenia (all p < 0.05), except for the back scratch test. In a model adjusted for sex, age and body mass index, slower 4-meter gait speed (OR = 1.29, 95%CI = 1.08 to 1.54), slower 8-foot up-and-go test time (OR = 1.32, 95%CI = 1.16 to 1.49), greater chair sit-and-reach test (OR = 0.97, 95%CI = 0.94 to 0.99) and higher self-reported Composite Physical Function scores (OR = 0.94, 95%CI = 0.89 to 0.99) were significantly associated with confirmed sarcopenia status. EWGSOP2 confirmed sarcopenia is prevalent in older people residing in Brazil's Northern region and is independently associated with slower walking speed and chair rising ability, reduced trunk and lower-limb flexibility, as well as poorer self-reported physical function.

Wind farm noise negatively impacts the calling behavior of three frogs in Caatinga dry forests.

Acoustic signals play a fundamental role in the lives of anurans. With the increasing prevalence of wind farms in Caatinga ecosystems, our goal was to assess whether the noise generated by this energy source poses a threat to anuran communication. We analyzed acoustic parameters of the advertisement calls from 181 adult males, of the species Scinax pachycrus, Scinax x-signatus, and Physalaemus cicada. Call activity was recorded across noise gradients in 19 temporary ponds with similar vegetation structures, distributed in two wind farms. Our results revealed a significant relationship between wind turbine noise and changes in acoustic parameters of the three species, distinctly influencing their spectral and temporal parameters of the advertisement calls. Dominant frequency, frequency range of Scinax pachycrus were affected by the noise, decreasing in noisier temporary ponds, while Scinax x-signatus decreased call amplitude and call pulses. On the other hand, Physalaemus cicada showed changes only in temporal variables, with reductions in call duration and call pulses, and an increase in call rate to cope whit noise in temporary ponds. Therefore, noise pollution becomes particularly concerning for the anurans of the Caatinga, as the areas of greatest interest for wind power generation overlap with priority areas for biodiversity conservation.

A new marker for predicting sentinel lymph node metastasis in early (cT1-2N0) breast cancer: Tumor-infiltrating lymphocytes (TILs).

Tumor-infiltrating lymphocytes (TILs) are associated with lymph node metastasis and prognosis in breast cancer. Therefore, we explored the value of TILs in predicting sentinel lymph node metastasis (SLNM) in patients with early-stage (cT1-2N0) breast cancer and provided a new method for preoperative assessment of SLNM status. This study included 337 patients with early-stage breast cancer who underwent surgery at our hospital from January 2022 to December 2023. The expression of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki-67 in the patients was assessed using immunohistochemistry (IHC). TILs in the core needle biopsy samples were evaluated histopathologically, and patients were divided into high and low TILs groups based on the density of TILs. Statistical analysis was conducted, and a predictive model was established. The study found that patients with high TILs had a significantly lower rate of SLNM compared to those with low TILs (P < 0.001). The cT stage and the level of TILs were identified as independent predictive factors for SLNM. The ROC curve analysis indicated that the density of TILs has good predictive efficacy for SLNM. Based on the results of the multivariate regression analysis, a nomogram predictive model for SLNM was constructed. Our study showed that the density of TILs and cT stage are independent predictive factors for SLNM in early-stage (cT1-2N0) breast cancer, and the predictive effect of TILs density on SLNM is significant in Luminal and triple-negative breast cancers.

Long-term outcomes of biodegradable versus 2nd generation durable polymer drug-eluting stents in PCI: Protocol for a systematic review and meta-analysis.

More than 3 million individuals globally experience STEMI each year, with percutaneous coronary intervention (PCI) as the preferred revascularization method. While second-generation Drug Eluting Stents (DES) reduce restenosis compared to bare-metal stents, complications such as neoatherosclerosis and stent thrombosis remain. Second-generation stents, including durable polymer (DP-DES) and biodegradable polymer (BP-DES), aim to improve outcomes, though guidelines do not specify a preference. Given mixed results from prior studies and new long-term data, we aim to perform a systematic review and meta-analysis comparing long-term outcomes of DP-DES vs. BP-DES following PCI. This protocol has been developed following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. MEDLINE, Embase, and Scopus databases will be searched for eligible observational and interventional studies from inception up to 5th of October 2024. Screening (title/abstract and full text), data extraction, risk of bias assessment, and quality of evidence assessment will be conducted by two independent reviewers. A random-effects model will be used to meta-analyse outcomes. DES have greatly advanced PCI for STEMI. However, long-term stent thrombosis remains an issue due to chronic inflammation and impaired healing from the stent's polymer coating. To overcome this, BP-DES were introduced to dissolve their coating within 2-9 months. However, whether BP-DES offers superior long-term outcomes compared to second-generation DP-DES remains uncertain. While previous meta-analyses have shown similar outcomes, recent studies suggest BP-DES may offer better long-term results. This review will compare long-term outcomes (≥5 years) of BP-DES vs. DP-DES, providing important insights to inform clinical practice. Systematic review registration: PROSPERO (CRD42024592579).

A randomized controlled trial of the effects of dog-assisted versus robot dog-assisted therapy for children with autism or Down syndrome.

Research with controlled or crossover designs in animal-assisted therapy have largely used control groups receiving no treatment or treatment as usual, which can potentially inflate the effects of these interventions. It is therefore not always clear whether this type of therapy has a positive effect on, for example, the social skills of children with special support needs. To address this, the current study compared children (7-16 years, n = 65) with autism or Down syndrome who received five sessions of dog-assisted therapy (n = 24; 9 female) with an active control group who received five similar sessions of robot dog-assisted therapy (n = 21; 8 female) and a no-treatment control group (n = 20; 8 female). The robot dog was capable of performing autonomous behavior and responding to the child's actions and verbalizations. Using parental questionnaires, we assessed children's social and emotional skills before and after the therapy sessions or waiting period and included a follow-up measurement after 4-6 weeks. On a group level, multilevel analyses showed that children who received dog-assisted therapy improved significantly more in terms of emotional attunement and emotion regulation than children in the two other conditions. No significant differences were found for social confidence, conversational attunement, social cognition, and social motivation. Change from post-test to follow-up was also less apparent. Yet, on a more individual level, when looking at the Reliable Change Index (RCI), most of the highest RCIs (within the 90th percentile) were found in the dog-assisted therapy group. In contrast, most of the lowest RCIs (within the 10th percentile) were found in the robot-assisted group. We discuss the pros and cons of a more individualized approach in this field of study and propose a possible alternative by focusing on interaction dynamics.

Pelvic floor disorders and associated factors among women in sub-Saharan Africa: A systematic review and meta-analysis protocol.

Pelvic floor disorders (PFDs) are a group of conditions caused by injured or weakened pelvic muscles, ligaments, connective tissues, and nerves that support or hold pelvic organs in place so they can function correctly. Common PFDs are pelvic organ prolapse (POP), urinary incontinence (UI), and faecal incontinence (FI). A preliminary search on the subject within the last decade identified no review protocol or systematic review, despite a significant percentage of women in SSA suffering from it. A comprehensive literature search will be gathered from electronic databases such as PubMed, Embase, Hinari, Cochrane Library, African Journals Online (AJOL), and Google Scholar. The protocol followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses for Protocol (PRISMA-P) guideline. All studies conducted in sub-Saharan African countries will be included regardless of their study design as long as these studies report the magnitude of the problem under study. Joanna Briggs Institute's (JBI) appraisal checklist will be used to assess the quality of individual studies. Heterogeneity will be checked using Cochrane Q test statistics and I2 test statistics, and a random-effects model will be employed to estimate the pooled prevalence of PFDs and its associated factors. The present study will estimate the pooled prevalence of pelvic floor disorders and their associated factors in sub-Saharan Africa countries. This review was registered on PROSPERO with registration number CRD42024578550.

Bioavailability of zinc from different organic zinc chelates and their effect on the growth, whole body, tissue zinc content, enzymes activity and proximate composition of L. rohita.

Minerals play an essential role in aquatic animals to maintain their normal physiological and metabolic functions. This feeding trial assessed the impact of various zinc sources on L. rohita performance. Dietary treatments included a Control group with zinc sulfate (226.25 mg/kg), and treatment groups with zinc citrate (150.15 mg/kg), zinc acetate (230.56 mg/kg), zinc monomethionine (244.75 mg/kg), and zinc gluconate (395.94 mg/kg). In 15 aquaria, 300 fish (15.84 ± 0.07g) were randomly distributed in triplicate groups. Results revealed significantly (P < 0.05) higher final body weight (FBW), feed conversion ratio (FCR), body weight gain (BWG), and sediment growth rate (SGR) for zinc gluconate fed fish compared to the other sources. Zinc gluconate fed L. rohita also exhibited the lowest feed intake, while initial body weight (IBW) and survival rate (SR %) did not significantly differ. Proximate fish analysis showed non-significant (P > 0.05) differences among treatments. Tissue zinc analysis demonstrated significantly (P < 0.05) higher zinc content in L. rohita receiving zinc gluconate. Antioxidant enzyme activity indicated lower (2.12 ± 0.01) thiobarbituric acid reactive substances (TBARS) in the zinc gluconate treatment, with elevated levels of key biomarker enzymes, glutathione peroxidase (GPx), catalase (CAT), and superoxide dismutase (SOD). Stress and immune response indicators revealed significantly lower hematocrit (HCT), cortisol (CRT), and glucose (GLU) levels in zinc gluconate fed fish, while CRT was higher (36.62 ± 0.65 mg/ml). Blood serum parameters, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP), remained lower (29.65 ± 0.85 U/ml, 84.76 ± 2.45 U/ml, and 212.87 ± 6.14 U/ml), in fish fed zinc gluconate respectively. In conclusion, different organic zinc sources, particularly zinc gluconate, improved L. rohita growth, tissue zinc concentration, antioxidant enzyme activity, blood serum parameters, and stress and immune response to varying extents.

Understanding climate-sensitive diseases in Bangladesh using systematic review and government data repository.

Understanding the effects of climate change on health outcomes is crucial for effective policy formulation and intervention strategies. However, in Low- and Middle-Income Countries, like Bangladesh, the true extent of these effects remains unexplored due to data scarcity. This study aims to assess available evidence on climate change-related health outcomes in Bangladesh, to compare it with actual national occurrences, and to explore challenges related to climate change and health data. We first conducted a systematic review to summarize the climate-sensitive diseases examined in existing literature in Bangladesh. The review results were then compared with over 2.8 million samples from the government's data repository, representing reported cases of climate-sensitive diseases during 2017-2022. This comparison aimed to identify discrepancies between the diseases currently occurring in Bangladesh related to climate change and available knowledge through existing research. Additionally, we also explored the limitations of the data recorded in the government data repository. The available literature in Bangladesh reports only a few specific climate-sensitive diseases, including Diarrhea, Dengue, Cholera, Malaria, Pneumonia, Cardiovascular Diseases, Hypertension, Urinary-Tract Infections, and Malnutrition, which were also considered in few studies. This represents a segment of the total 510 reported climate-sensitive diseases in Bangladesh, of which 143 diseases were responsible for 90.66% of the total occurrences. The most common forms of diseases were diarrhea and gastroenteritis of presumed infectious (28.51%), pneumonia (18.88%), anxiety disorders, panic disorders, generalized anxiety disorders (13.2%), and others (13.15%). Additionally, Urinary-Tract infections (7.87%), cholera (3.03%), and typhoid fever (3.27%) were other frequently reported climate-sensitive diseases. We also explored several challenges related to available data in the government repository, which include inadequate collection of patients' comprehensive socio-demographic information and the absence of a unique patient identifier. The findings underscore the urgent need to tackle data challenges in understanding climate-sensitive diseases in Bangladesh. Policies and programs are required to prioritize the digitalization of the healthcare system and implement a unique patient identification number to facilitate accurate tracking and analysis of health data. Climate Change, including rising temperature and extreme weather events like cyclone and floods, poses a significant global health threat [1]. The World Health Organization estimates climate change already causes at least 150,000 deaths annually at the global level, and that number is projected to double by 2030. Beside these other impact of climate change are far-reaching, leading to forced displacement, malnutrition and increased incidence of diseases such as dengue, diarrhea, and pneumonia [2]. Additionally, climate change has established links to mental health issues, like anxiety and depression [3]. The effects are particularly severe in Low- and Middle-Income Countries (LMICs) due to limited resources and inadequate infrastructure for coping with erratic weather and disasters [4]. We undertook a comprehensive mixed-method study, incorporating a systematic review of existing studies conducted in Bangladesh, along with an analysis of government data repository. A detailed description of each component is presented below.

CFD-based design of air wall water blocking for underground garage entrances and exits.

In the increasingly perfect underground garage construction process, the underground garage entrance water blocking problem is getting more and more attention. This paper proposes a kind of air wall water-blocking device applied to underground garage. The device is installed on the side of the straight and curved paths at the entrances and exits of the spiral underground garage. It utilizes two fans to blow the water to the drain on the other side to achieve unobstructed access to stop the water. In this paper, CFD simulation is firstly carried out on the straight road of the spiral underground garage to verify the feasibility of the program. The accuracy of the simulation results was verified by building a straight road model and conducting experiments. After that, an equal-scale 3D model of the spiral underground garage was built. Orthogonal experiments on the effects of inlet water flow velocity, fan wind speed at the straight road and fan wind speed at the curved road on the water blocking effect were carried out by using CFD simulation. A preliminary range of water velocity of 2.250 m/min to 6.786 m/min was obtained experimentally, and this range of water velocity was used as an input parameter for the simulation. The results show that the speed of water flow at the entrance of the garage and the wind speed of the fan at the straight road have a greater effect on the water blocking effect than the wind speed of the fan at the curved road. When the wind speed of the fan at the straight road is 25m/s, proper adjustment of the wind speed of the fan at the curved road can realize a good water-blocking effect of the spiral underground garage entrance within the range of water flow rate of 2.250m/min ~ 6.786m/min. Therefore, in the practical application of using the air wall water blocking scheme to realize the underground garage entrance water blocking strategy is to give priority to improve the wind speed of the fan at the straight road to improve the effect of water blocking.
