Isolated and Combined Effects of Sedentary Behaviour and Physical Activity on Muscle Strength in Older Adults: A Prospective Cohort Study

ABSTRACT

Aim

We aim the isolated and combined effects of sedentary behaviour exposure time and physical activity levels on muscle strength in older adults.

Design

This prospective observational cohort study, analytical in nature, using exploratory survey methods and physical performance testing. With 5-year longitudinal follow-up (2015–2020).

Methods

A total of 459 older adults participated in the baseline, with a total of 224 being included/located again in the follow-up. We evaluate muscle strength using handgrip tests and sit-to-stand tests. The international physical activity questionnaire was used to measure physical activity and sedentary behaviour. Generalised Estimation Equations tested both independent and combined effects, reporting results as β coefficients and confidence intervals.

Results

Older adults exhibiting low sedentary behaviour displayed enhanced handgrip strength compared to those with high sedentary behaviour. Notably, older adults who were sufficiently active with low sedentary behaviour, sufficiently active with high sedentary behaviour, and insufficiently active with low sedentary behaviour showed increased handgrip strength compared to their counterparts who were insufficiently active with high sedentary behaviour. This trend was consistent for lower limb strength.

Conclusion

Interventions that encourage a reduction in sedentary behaviour and an increase in physical activity are essential to maintain muscle strength among older adults.

Implications for Practice

The findings of this study underscore the importance of addressing both sedentary behaviour and physical activity levels in clinical interventions aimed at preserving muscle strength in older adults. Routine assessments of physical activity and sedentary behaviour could help tailor personalised exercise programs, potentially enhancing functional independence and reducing the risk of frailty and disability in older patients.

Patient or Public Contribution

Patients were involved in the sample of the study.

Reporting Method

This study was conducted in accordance with the Strengthening Research in Observational Studies in Epidemiology (STROBE) guidelines.

Internal Regulation Core as a hub of disruptive innovation in hospital management: a scoping review protocol

Por: Gomes · L. M. · Moreira · F. d. M. B. · Junior · G. F. X. · Duani · H. · Andrade · M. V. M. d. · Ferrari · T. C. A.
Introduction

This scoping review protocol aims to examine the role of the Internal Regulation Core (IRC) as an intra-hospital governance structure that coordinates capacity and patient flow and may function as a strategic hub for disruptive innovation in hospital management. By integrating organisational routines, rules and, when available, enabling technologies, IRCs may strengthen operational efficiency and contribute to higher-quality care delivery. As hospitals face increasing operational complexity and constrained resources, clarifying what IRCs are, how they are implemented across settings, and what innovations and impacts are reported has become a priority.

Methods and analysis

This scoping review will follow the Joanna Briggs Institute guidance and Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. A comprehensive search will be conducted across five databases (MEDLINE/PubMed, Embase, Scopus, Web of Science and LILACS) and grey literature sources, without language or date restrictions. The searches were conducted up to 6 July 2025. Two reviewers will independently screen studies and extract data using a standardised form; disagreements will be resolved by consensus or a third reviewer. Findings will be synthesised descriptively and thematically, with results presented in tables and narrative summaries, including innovation streams.

Introduction

In Togo, the syndromic approach is used for the diagnosis and management of sexually transmitted infections (STIs). The aim of this study was to evaluate the syndromic approach for diagnosis of STIs among female sex workers (FSW) in Lomé, Togo.

Methods

A cross-sectional study was carried out from September to October 2023 among FSW in Lomé (Togo). FSW aged 18 years and above were included. A gynecological examination was performed for syndromic diagnosis, and the Xpert® CT/NG were used to screen vaginal swabs for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG). The performance (predictive values) of the syndromic approach to STI diagnosis was evaluated using the Xpert® CT/NG test as the gold standard.

Results

A total of 357 FSW were recruited. The median age of FSW was 32 years (IQR: [26–40 years]) and 8.2% had attained a higher level of education. The prevalence of syndromic STI among FSW was 33.3%. Vaginal swabs were positive for CT (8.4%) and NG (8.7%), with a prevalence of bacterial STIs (CT and/or NG) of 14.3%. The syndromic approach to STI diagnosis demonstrated a positive predictive value of 24.3%.

Conclusion

The prevalence of STIs is relatively high among FSW in Lomé. According to this study, the diagnosis of STIs using the syndromic approach has limited relevance. National STI screening and management policies urgently need to be rethought, incorporating recent technological advances.

Food pricing: A study on the sales of food in Brazilian private schools

by Ariene Silva do Carmo, Paulo César Pereira de Castro Júnior, Thais Cristina Marquezine Caldeira, Daniela Silva Canella, Rafael Moreira Claro, Luiza Delazari Borges, Larissa Loures Mendes

The present study analyzed the prices of food sold in canteens of Brazilian private schools and described price-based marketing strategies, according to the NOVA food classification system. This is a mixed methods study combining a cross-sectional component and time series analysis, with data from 2,241 canteens in private elementary and secondary schools in the 26 capitals of Brazil and the Federal District, collected between June 2022 and June 2024. Price data collected for unprocessed, minimally processed, or processed foods and culinary preparations based on these foods (UMPCP), and ultra-processed foods and culinary preparations based on these foods (UpCP) sold in school canteens and from the National System of Consumer Price Indices (SNIPC), were used to create a data set containing deflated monthly prices for food and beverages sold between August 2022 and July 2024. Calculations were made for adjusted prices (R$/100 g or ml) and absolute prices (R$ per portion), and frequency of use of strategies such as combos and promotions. UMPCP showed lower adjusted price, but higher absolute price than UpCP, especially for solid foods. About 27% of the study canteens implemented pricing strategies for both food groups. Most of these strategies did not exclusively favor healthy foods, indicating that promotions and combos were used without distinction. The affordability of healthy foods is disadvantaged in school canteens when considering the price per portion, which may negatively influence students’ food choices. The findings show that current prices for food sold in most canteens discourage the purchase of healthy items, but favor the purchase of unhealthy ones. These results reinforce the importance of interventions for promoting healthy foods and making them more affordable.

Prognostic significance of tumour-infiltrating T lymphocytes in ovarian cancer: a protocol for systematic review and meta-analysis

Introduction

Ovarian cancer remains a significant clinical challenge due to its aggressive nature and high mortality rate. Tumour-infiltrating lymphocytes (TILs) play a critical role in the tumour microenvironment, influencing treatment response and patient survival across various cancer types, including ovarian cancer. A systematic review is warranted to consolidate evidence on TILs as prognostic biomarkers in ovarian cancer, with the goals of integrating them into clinical practice to enhance patient outcomes. This study aims to assess the prognostic significance of TILs in ovarian cancer.

Methods and analysis

A comprehensive literature search will be conducted across multiple databases, including PubMed, Embase, Web of Science, Scopus, Cochrane Library, CINAHL, ScienceDirect and LILACS. No restrictions regarding publication date or language will be applied. Original studies evaluating the role of TILs in women with ovarian cancer will be considered for inclusion. Two independent authors will screen titles and abstracts, and any discrepancies will be resolved through discussion with a third author. The risk of bias in included studies will be assessed using the Quality in Prognosis Studies (QUIPS) tool. Data synthesis will be performed using R software (V.4.3.1).

Ethics and dissemination

This study reviews the published data; thus, obtaining ethical approval is unnecessary. The findings of this systematic review will be published in a peer-reviewed journal.

Introduction

Photobiomodulation therapy (PBMT), particularly when combined with a static magnetic field (PBMT-sMF), is a promising non-pharmacological approach for managing musculoskeletal disorders. However, high-quality evidence for its efficacy in lateral epicondylitis remains limited.

Objectives

The study aims to investigate the effectiveness of PBMT-sMF vs placebo in reducing pain, improving function and modulating inflammatory markers in individuals with lateral epicondylitis.

Design

Multicentre, randomised, triple-blinded, placebo-controlled trial.

Setting

Three outpatient physiotherapy clinics in Brazil.

Participants

50 adults (18–50 years) with unilateral lateral epicondylitis and baseline pain ≥50 on the visual analogue scale (VAS).

Interventions

Participants received either active PBMT-sMF (n=25) or placebo (n=25), 2 times per week for 3 weeks. PBMT-sMF involved multi-wavelength irradiation at 4 epicondyle sites (60 s; 27.1 J/site). The placebo group underwent the same procedure without active irradiation.

Primary and secondary outcome measures

The primary outcome was degree of pain rating (VAS). Secondary outcomes included forearm disability (Patient-Rated Tennis Elbow Evaluation, PRTEE), grip strength, serum tumour necrosis factor-alpha (TNF-α) levels and treatment satisfaction. Assessments were conducted at baseline, post-treatment (3 weeks) and at 4-week follow-up.

Results

PBMT-sMF yielded a higher responder rate (defined as the proportion of participants achieving at least a 30% reduction in pain intensity relative to baseline) than placebo (72% vs 40%, p=0.045), with a clinically and statistically significant between-group difference. Compared with placebo, the PBMT-sMF group showed significantly greater reductions in pain intensity both at the end of treatment (51.4±19.8 vs 36.9±22.6; p=0.0223) and at follow-up (37.4±24.1 vs 20.3±21.2; p=0.0049). TNF-α levels also decreased significantly in the PBMT-sMF group compared with placebo at both time points (p

Conclusions

PBMT-sMF significantly reduced pain intensity and TNF-α levels, suggesting an anti-inflammatory mechanism. Although functional outcomes were not improved, PBMT-sMF may be a valuable short-term, non-invasive option for lateral epicondylitis pain management.
