Background: Older adults often struggle to find footwear suitable for their clinical needs, thus affecting mobility, safety, and quality of life. Proper footwear is important due to fall risk, balance impairments, knee osteoarthritis (OA), hallux rigidus, plantar fasciitis, diabetic neuropathy, and limb length discrepancies (LLDs). Barriers such as inadequate clinical guidance and limited patient understanding persist. This paper provides updated, evidence-based recommendations for these challenges.

Methods: A topic review was conducted to evaluate shoe wear characteristics that address geriatric needs. Recommendations were synthesized from more than 45 years of clinical experience in physical therapy and categorized by clinical conditions. Evidence identified effective shoe features, including sole stiffness, tread patterns, heel elevation, and orthotic modifications to improve function, reduce pain, and reduce fall risk.

Results: Balance and fall risk: Shoes with wide soles, medium-firm materials, low heels, and high collars improved stability and reduced postural sway. Cupped, rigid insoles enhanced dynamic control, while treaded rubber outsoles minimized slipping. Knee OA: Flexible shoes with laterally wedged insoles and minimal heel lift reduced medial knee loads and pain. Supportive shoes and medially wedged insoles decreased lateral knee loads and pain. Hallux rigidus/bunions: Rocker-bottom shoes and stiffer soles accommodate deformities, improving function and comfort. Plantar fasciitis: Orthoses, supportive therapies, and stretching regimens were efficacious. Diabetic neuropathy: Rigid rocker soles and custom insoles reduced plantar pressure and ulcer recurrence. LLDs: Gradual shoe lift introduction alleviated low back pain. General recommendations: Properly fitted, comfortable shoes with moderately firm insoles, slip-resistant outsoles, and secure fastening mechanisms improve safety and function.

Conclusions: Footwear significantly impacts the mobility, safety, and well-being of older adults. Tailored recommendations enhance pain management, independence, and fall prevention. Providers should involve patients in decisions and counsel against the use of slippers or excessively elevated heels.

Importance: Prenatal cannabis use continues to increase, and cannabis remains the most commonly used illegal substance in pregnancy. Accumulating evidence suggests potential adverse effects on fetal and neonatal outcomes following cannabis use in pregnancy.

Objective: To update a living systematic review and meta-analysis to provide a timely understanding regarding cannabis use in pregnancy and fetal and neonatal outcomes.

Data sources: The previous review was updated by searching bibliographic databases MEDLINE, CINAHL, PsycInfo, Global Health, and Evidence-Based Medicine Reviews Cochrane Database of Systematic Reviews from November 1, 2021, through April 4, 2024.

Study selection: Cohort or case-control studies comparing pregnancies with and without prenatal cannabis use on prespecified fetal or neonatal outcomes with adjustment for confounders, such as co-use of tobacco products, were included. Two independent reviewers screened studies, with disagreements resolved through discussion.

Data extraction and synthesis: Included studies were extracted by 1 reviewer and confirmed by a second. Risk of bias was assessed with the Newcastle-Ottawa Scale. Random-effects meta-analyses of unadjusted and adjusted odds ratios (ORs) were performed for all primary outcomes. Results were synthesized using the Grading of Recommendations Assessment, Development, and Evaluation approach.

Main outcomes and measures: Primary outcomes were preterm birth (PTB; <37 weeks of gestation), small for gestational age (SGA), low birth weight (LBW; <2500 g), and perinatal mortality.

Results: For this update, 8 new studies with 1 709 998 participants were added, for a total of 51 studies synthesized (N = 21 146 938). From meta-analyses of adjusted effect sizes, moderate-certainty evidence indicated that cannabis use in pregnancy was associated with increased odds of LBW (20 studies; OR, 1.75; 95% CI, 1.41-2.18), PTB (20 studies; OR, 1.52; 95% CI, 1.26-1.83), and SGA (12 studies; OR, 1.57; 95% CI, 1.36-1.81), and low-certainty evidence indicated that it was associated with greater odds of perinatal mortality (6 studies; OR, 1.29; 95% CI, 1.07-1.55). Previously, the evidence was rated as very low or low certainty.

Conclusions and relevance: Cannabis use in pregnancy was associated with greater odds of PTB, SGA, and LBW even after adjusting for co-use of tobacco products, and confidence in these findings increased from low in the prior review to moderate in the current meta-analysis. The findings of this study may help inform patient counseling and future public health policies.

What is already known about this topic?

Binge drinking increases the risk for adverse health conditions and death. Alcohol screening and brief intervention (SBI), recommended by the U.S. Preventive Services Task Force (USPSTF) for all adults in primary care, is effective in reducing binge drinking.

What is added by this report?

In 2017, 81% of survey respondents were asked by their health care provider about alcohol consumption and 38% about binge drinking at a checkup in the past 2 years. Among those asked about alcohol use and who reported current binge drinking, 80% received no advice to reduce their drinking.

What are the implications for public health practice?

Implementation of alcohol SBI as recommended by USPSTF, coupled with population-level evidence-based interventions, can reduce binge drinking among U.S. adults.
