Grading the evidence for physical activity and any outcome in cancer survivors: An Umbrella review of 740 meta-analytic associations.

Background: To contribute to the refinement of future physical activity (PA) guidelines, which have remained mostly generic until now, we performed an umbrella review of meta-analyses for PA in cancer survivors.

Methods: Medline and Scopus databases were searched in January 2024 for systematic reviews and meta-analyses on the association/effect of any type of PA in every cancer type and for any studied outcome. Statistically significant meta-analyses were categorized into four evidence groups (strong, highly suggestive, suggestive, weak) using pre-established grading criteria.

Breakthrough in RAS targeting with pan-RAS(ON) inhibitors RMC-7977 and RMC-6236.

The multi-selective tri-complex RAS(ON) inhibitors RMC-7977 and RMC-6236 signal new avenues for RAS targeting. This systematic review aims to comprehensively present the available preclinical and early clinical data on these agents. We screened Medline, Scopus, the ESMO and ASCO conference sites and ClinicalTrials.

Associations of blood lipids and LDL cholesterol lowering drug-targets with colorectal cancer risk: a Mendelian randomisation study.

Background: Whether blood lipids are causally associated with colorectal cancer (CRC) risk remains unclear.

Methods: Using two-sample Mendelian randomisation (MR), our study examined the associations of genetically-predicted blood concentrations of lipids and lipoproteins (primary: LDL-C, HDL-C, triglycerides, and total cholesterol), and genetically-proxied inhibition of HMGCR, NPC1L1, and PCSK9 (which mimic therapeutic effects of LDL-lowering drugs), with risks of CRC and its subsites. Genetic associations with lipids were obtained from the Global Lipids Genetics Consortium (n = 1,320,016), while genetic associations with CRC were obtained from the largest existing CRC consortium (n = 58,221 cases and 67,694 controls).

Treatment outcomes among patients with isoniazid mono-resistant tuberculosis in Mumbai, India: A retrospective cohort study.

Background: Tuberculosis (TB) remains a significant cause of mortality globally, with India accounting for 27% of the estimated number of people with TB. Multidrug-resistant TB (MDR-TB) and isoniazid (INH) resistance pose additional challenges to effective treatment. We aimed to describe treatment outcomes of INH mono-resistant TB patients under programmatic conditions in Mumbai, India.

Allometric fat mass index and alanine aminotransferase attenuate the associations of platelet parameters with lung cancer risk.

We have previously shown that body mass index attenuates a positive association of platelet count (PLT) and inverse of mean platelet volume (MPV) with lung cancer risk in men. It is unclear whether fat mass, lean mass, or liver function tests (LFTs) show similar attenuations. Using bioelectrical impedance measurements (UK Biobank cohort) and multivariable Cox proportional hazards models, we examined the associations of allometric fat-mass index (AFI, fat mass adjusted for height), allometric lean-mass index (ALI, fat-free mass adjusted for height and fat mass), and LFTs with lung cancer risk and their multiplicative and additive interactions with platelet parameters.

Temporal trajectories of long-COVID symptoms in adults with 22 months follow-up in a prospective cohort study in Norway.

Objectives: There is a lack of large studies on long-COVID symptoms with symptoms measurements before the onset of COVID-19. Therefore, long-COVID is still poorly defined.

Methods: The Norwegian COVID-19 Cohort Study is a population-based, open cohort of adult participants (aged 18-96 years) from Norway.

Usability and acceptability of self-testing for hepatitis C virus exposure in a high-prevalence urban informal settlement in Karachi, Pakistan.

Background: Hepatitis C virus (HCV) antibody self-testing (HCVST) may help expand screening access and support HCV elimination efforts. Despite potential benefits, HCVST is not currently implemented in Pakistan. This study aimed to assess the usability and acceptability of HCVST in a high HCV prevalence informal settlement in Karachi, Pakistan.

Association of inflammatory cytokines with lung function, chronic lung diseases, and COVID-19.

We investigated the effects of 35 inflammatory cytokines on respiratory outcomes, including COVID-19, asthma (atopic and non-atopic), chronic obstructive pulmonary disease (COPD), and pulmonary function indices, using Mendelian randomization and colocalization analyses. The emerging associations were further explored using observational analyses in the UK Biobank. We found an inverse association between genetically predicted macrophage colony stimulating factor (MCSF), soluble intercellular adhesion molecule-1 (sICAM), and soluble vascular cell adhesion molecule-1 with risk of COVID-19 outcomes.

Circulating inflammatory and immune response proteins and endometrial cancer risk: a nested case-control study and Mendelian randomization analyses.

Background: Inflammation and immune dysregulation are hypothesized contributors to endometrial carcinogenesis; however, the precise underlying mechanisms remain unclear.

Methods: We measured pre-diagnostically 152 plasma protein biomarkers in 624 endometrial cancer case-control pairs nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Odds ratios (ORs) were estimated using conditional logistic regression, accounting for confounding and multiple comparisons.

Incidence of prostate, colorectal and male breast cancers in relation with statins and testosterone replacement therapy: SEER-Medicare 2007-2015.

Introduction: Statins and testosterone replacement therapy (TTh) have been inconsistently associated with a reduced risk of hormone-related cancers (HRCs, prostate [PCa], colorectal [CRC], and male breast cancers [BrCa]). Yet, the joint association of statins and TTh with the incidence of these cancers, and whether these associations vary by race, remains poorly understood. The objective of this retrospective cohort study is to examine the independent and joint effects of pre-diagnostic use of statins and TTh on the risk of HRCs, including PCa, CRC, and male BrCa.

Elucidating the non-genetic risk factors for celiac disease: an umbrella review of meta-analyses.

The breadth and validity of the associations of nongenetic risk factors with celiac disease (CeD) are elusive in the literature. We aimed to evaluate which of these associations have strong epidemiological credibility and assessed presence and extent of potential literature biases. We systematically searched PubMed until April 2024 for systematic reviews and meta-analyses of studies examining associations between putative risk factors and CeD.

Bone Mineral Density in Survivors of Childhood Cancer: A Meta-Analysis.

Context: There is an increasing population of childhood cancer survivors (CCS) at risk for treatment-related toxicities, including skeletal morbidities. Bone mineral density (BMD) is a proxy for bone health and reductions are associated with osteoporosis and fractures.

Objective: To investigate bone health in CCS by conducting a systematic review and meta-analysis of BMD after completed treatments.

Non-genetic factors and breast cancer: an umbrella review of meta-analyses.

Background: Previous research has found associations between various non-genetic factors and breast cancer (BrCa) risk. This study summarises and appraises the credibility of the available evidence on the association between non-genetic factors and BrCa risk.

Methods: We conducted an umbrella review of meta-analyses.

Treatment Adherence and Health Status of Patients With COPD Under Treatment With Salmeterol/Fluticasone via the Elpenhaler® Device: The AHEAD Study.

Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous progressive lung condition characterized by long-term respiratory symptoms and airflow limitation. Appropriate bronchodilation is the cornerstone of COPD treatment, leading to better health status as well as benefits in prognosis and mortality.

Methods: In the current open, noninterventional, observational study, 716 patients diagnosed with COPD of variable severity were administered a fixed-dose combination (FDC) of fluticasone propionate and salmeterol (500 + 50 mcg) through the Elpenhaler® device.

The dietary changes during Ramadan and their impact on anthropometry, blood pressure, and metabolic profile.

Background: The effect of Ramadan intermittent fasting (RIF) on the metabolic profile, anthropometry and blood pressure has been investigated in multiple studies. However, it is still unknown to what extent changes in nutrient intakes contribute to these changes.

Methods: This observational study was conducted in London (UK) in 2019.

Safety of intravitreal chemotherapy in the management of retinoblastoma: A systematic review of the literature.

Intravitreal chemotherapy is used as a salvage therapy for retinoblastoma with persistent or recurrent vitreous seeding after primary treatment. To assess the safety of this technique, we conducted a systematic review of all studies reporting ocular toxicity data. Forty-eight trials involving 2751 eyes were included.

The effect of SGLT2 inhibitors and GLP1 receptor agonists on arterial stiffness: A meta-analysis of randomized controlled trials.

Background: Pulse wave velocity (PWV) and augmentation index (AIx) are indices used to assess arterial stiffness. We evaluated the effect of sodium glucose co-transporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1-RA) on arterial stiffness indices.

Methods: We searched PubMed (up to January 2024) for RCTs assessing the effect of SGLT2i or GLP1-RA on arterial stiffness with reporting outcomes PWV and AIx.

Effects of antipsychotic medications in glucose and lipid metabolism at the fasted state in drug-naïve first episode patients with psychosis after six months and three years of treatment.

Diabetes and dyslipidemia are common in patients with psychosis and may be related to adverse effects of antipsychotic medications. Metabolic disturbances in first-episode patients with psychosis are common, even prior to any antipsychotic treatment, and antipsychotic medications are implicated in the development of metabolic syndrome, at least in the long run. We therefore aimed to follow a group of drug-naïve, first-episode patients with psychosis at different time points (baseline, six months, and 36 months after the initiation of antipsychotic treatment) in order to evaluate the progression of metabolic abnormalities after antipsychotic therapy and the time-course of their onset.
