Importance: Accurate assessment of intravascular volume facilitates management decisions about fluid management in patients with volume overload.

Objective: To identify the most accurate clinical examination, radiographic, and laboratory findings for assessing volume overload in nonintubated patients.

Data sources and study selection: MEDLINE was searched (1946 to January 6, 2026) to identify peer-reviewed English-language studies about the diagnostic accuracy of the clinical examination of spontaneously breathing patients with intravascular volume overload.

Data extraction and synthesis: Three authors independently extracted data for each finding and calculated sensitivity, specificity, and likelihood ratios (LRs). A 2-level mixed logistic regression model was used to pool estimates.

Results: Forty studies, involving 11 490 adult patients, were included, with a prevalence of volume overload of 35% to 69%. Thirty-three of those studies evaluated patients with dyspnea. Prevalence of volume overload was more likely when the physical examination revealed jugular venous distention with the highest point of pulsation more than 3 cm in a vertical line above the sternal angle (LR, 4.1 [95% CI, 2.9-5.6]; specificity, 92%), lower extremity edema (LR, 2.2 [95% CI, 1.5-3.1]; specificity, 80%), or crackles on auscultation (LR, 2.7 [95% CI, 1.7-4.5]; specificity, 81%). Vascular congestion on chest radiography increased the likelihood of intravascular volume overload (LR, 5.9 [95% CI, 2.9-12.0]; specificity, 91%). Point-of-care ultrasonography that identified bilateral pulmonary B-lines suggested volume overload (LR, 4.0 [95% CI, 2.6-6.1]; specificity, 77%), and absence of pulmonary B-lines made volume overload unlikely (LR, 0.09 [95% CI, 0.04-0.23]; sensitivity, 93%). Inferior vena cava collapsibility index of less than 50% increased the likelihood of volume overload (LR, 3.9 [95% CI, 2.5-6.1]; specificity, 79%), and a collapsibility index of at least 50% made it less likely (LR, 0.22 [95% CI, 0.11-0.45]; sensitivity, 82%). Point-of-care ultrasonographic measurement of jugular venous pressure (JVP; >8 cm) also increased the likelihood of volume overload (LR, 2.8 [95% CI, 2.2-3.5]; specificity, 71%), although JVP of 8 cm or less identified patients less likely to have volume overload (LR, 0.26 [95% CI, 0.20-0.33]; sensitivity, 81%). A plasma brain-type natriuretic peptide (BNP) level of 100 ng/mL or higher was the single best test to identify those most likely to have volume overload (LR, 6.9 [95% CI, 2.4-20.4]; specificity, 87%), and a normal value made it less likely (LR, 0.14 [95% CI, 0.08-0.24]; sensitivity, 87%).

Conclusions and relevance: A BNP level of 100 ng/mL or higher and presence of vascular congestion on chest radiography may be the most useful tests to identify patients with volume overload. Absence of pulmonary B-lines using point-of-care ultrasonography or BNP levels of less than 100 ng/mL may be most useful to exclude volume overload.

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.

Background: This cross-sectional study aimed to describe proportions of patients with indications of alcohol consumption using phosphatidylethanol (PEth), the Alcohol Use Disorders Identification Test (AUDIT), and its consumption-focused version (AUDIT-C), in relation to blood pressure (BP) control, overall and by sex.

Methods: A total of 270 hypertensive primary care patients (ICD-10: I10.9) were stratified into BP control groups: controlled (<140/90 mmHg), uncontrolled (≥140/90 mmHg), and apparent treatment-resistant hypertension (aTRH; ≥140/90 mmHg with ≥3 antihypertensive drugs). A randomized sample from each stratum was invited, baseline data were collected. Alcohol consumption using predefined categories for PEth and AUDIT, and hazardous use (PEth ≥ 0.122 µmol/L; AUDIT ≥ 8; AUDIT-C ≥ 5 for men, ≥4 for women), were analyzed in relation to BP control groups.

Results: Mean age was 67 ± 11 years; 42% were women. PEth indicated high and regular alcohol consumption in 6.4% of controlled, 5.3% of uncontrolled, and 19.2% of aTRH patients (controlled vs. aTRH, P = .027; uncontrolled vs. aTRH, P = .013). AUDIT showed no significant differences in hazardous use between BP groups (P = .865). AUDIT-C identified slightly higher proportions of hazardous use than PEth, across BP groups and sexes. No significant differences were found between BP groups for hazardous use by PEth (P = .339) or AUDIT-C (P = .150).

Conclusions: PEth revealed significantly higher alcohol use in the aTRH group, undetected by AUDIT. AUDIT-C and PEth identified more hazardous use than AUDIT, suggesting their potential to prompt alcohol-related discussions and support evidence-based hypertension care. PEth correlated more strongly with AUDIT-C than with AUDIT.

Background
Vitamin B12 deficiency is common in the elderly population and can cause severe complications. The use of certain medication has in previous studies been associated with vitamin B12 deficiency in the general population. To identify elderly patients at risk for vitamin B12 deficiency due to medication use, we evaluated the association between medication use and vitamin B12 deficiency in the elderly population.

Methods
Hospitalized geriatric patients 65 years of age or over with a serum vitamin B12 measurement within one week of the admittance date were included. Patients were classified as either B12 normal (258–635 pmol/L) or B12 deficient (< 148 pmol/L). Upon hospital admission patients’ medication use was verified. The association between vitamin B12 deficiency and the use of antacid, antiepileptic, antidiabetic, lipid lowering and other medication was evaluated by univariate and multivariate analyses.

Results
Of the 7132 patients included in the study, 532 (7.5%) had vitamin B12 deficiency and 3433 (48.1%) patients had normal vitamin B12 concentrations. Metformin use was significantly and independently (adjusted OR 2.5; 95% CI 1.7–3.6) associated with a dose-dependent higher risk of vitamin B12 deficiency. The use of other medication evaluated in this study was not associated with vitamin B12 deficiency.

Conclusions
Metformin use is significantly associated with vitamin B12 deficiency in the elderly, and this risk rises with higher metformin doses. Monitoring and timely start of vitamin B12 supplementation along with the lowest possible metformin dose are essential to prevent complications.
