Bedside Physical Examination for the Diagnosis of Aortic Stenosis: A Systematic Review and Meta-analysis.

Background: Patients with obstruction to the left ventricular outflow tract from degenerative aortic stenosis (AS) usually do not become symptomatic until their disease becomes graded as severe. We sought to assess the accuracy of the physical examination for the diagnosis of AS of at least moderate severity. Methods: A systematic review and meta-analysis of case series and cohorts of patients who received a cardiovascular physical examination prior to receiving a left heart catheterization or an echocardiogram. PubMed, Ovid MEDLINE, the Cochrane Library, ClinicalTrials.gov, and Embase were searched with a date range from inception through December 10, 2021, without language restrictions. Results: Our systematic review yielded 7 observational studies with adequate data to perform a meta-analysis on 3 physical examination assessments. Auscultating a diminished second heart sound (likelihood ratio [LR] = 10.87, 95% confidence interval [CI], 3.94-30.12, P < 0.05) and palpating a delayed carotid upstroke (LR = 9.04, 95% CI, 3.12-25.44, P < 0.05) are useful for detecting AS of at least moderate severity. The absence of a systolic murmur radiating to the neck (LR = 0.11, 95% CI, 0.06-0.23, P < 0.05) rules against AS of at least moderate severity. Conclusions: Low-quality evidence from observational studies supports a diminished second heart sound and a delayed carotid upstroke as having moderate accuracy in diagnosing the presence of AS of at least moderate severity, whereas the absence of a murmur radiating to the neck is equally accurate in excluding this diagnosis.

Contexte: Les patients présentant une obstruction de la voie d'éjection ventriculaire gauche consécutive à une sténose aortique (SA) dégénérative ne montrent habituellement pas de symptômes avant que la maladie ne soit de grade sévère. Nous cherchions donc à évaluer la fiabilité des examens physiques dans le diagnostic de SA modérée ou plus grave. Méthodologie: Une revue systématique et une métanalyse de séries de cas et de cohortes de patients qui ont subi un examen cardiovasculaire avant de recevoir un cathétérisme du côté gauche du cœur ou un échocardiogramme ont été effectuées. Les bases de données PubMed, Ovid MEDLINE, Cochrane, ClinicalTrials.gov et Embase ont été interrogées pour trouver les études publiées entre la date de début de l'indexation des bases jusqu'au 10 décembre 2021, sans restriction quant à la langue de publication. Résultats: Notre revue systématique a permis de relever sept études observationnelles contenant des données permettant de réaliser une métanalyse sur trois examens physiques. La présence d'un deuxième bruit diminué à l'auscultation (quotient de vraisemblance [QV] : 10,87; intervalle de confiance [IC] à 95 % : 3,94 à 30,12; p < 0,05) et d'un flux carotidien démodulé à la palpation (QV : 9,04; IC à 95 % : 3,12 à 25,44; p < 0,05) permet de détecter une SA modérée ou plus grave. L'absence d'un souffle systolique irradiant jusqu'au cou (QV : 0,11; IC à 95 % : 0,06 à 0,23; p < 0,05) permet d'éliminer la possibilité de SA modérée ou plus grave. Conclusions: Les données de faible qualité provenant d'études observationnelles témoignent d'une fiabilité modérée d'un deuxième bruit diminué et d'un flux carotidien démodulé dans le diagnostic de SA modérée ou plus grave, alors que l'absence d'un souffle irradiant jusqu'au cou présente la même fiabilité dans l'exclusion de ce diagnostic.

Vitamin D insufficiency and serum levels related to the incidence and stage of cutaneous melanoma: a systematic review and meta-analysis.

Cutaneous melanoma (CM) is the deadliest skin cancer, and vitamin D insufficiency has been suggested as a risk factor. We evaluated the relationship between both vitamin D insufficiency and 25-hydroxy vitamin D levels with the incidence and stage of CM. Five databases were searched from inception until 11 July 2022. Inclusion criteria were cohort and case-control studies that reported mean 25-hydroxy vitamin D levels or the presence of vitamin D insufficiency in CM patients and compared with healthy controls; or those that reported vitamin D insufficiency and Breslow tumor depth or the development of metastasis in CM. Fourteen studies were included in the analysis. Statistically significant relationships were found between vitamin D level <20 ng/dl and incidence of CM [pooled RR 1.45, 95% confidence interval (CI) 1.04-2.02]; lower mean vitamin D level and Breslow depth >1 mm (SMD 0.19, 95% CI 0.11-0.28); and vitamin D level >20 ng/dl and Breslow depth <1 mm (pooled RR 0.69, 95% CI 0.58-0.82). Statistical significance was not found in the relationships between vitamin D levels and the presence of metastasis (pooled SMD -0.13, 95% CI, -0.38 to 0.12); or mean vitamin D level and the incidence of CM (pooled SMD -0.39, 95% CI, -0.80 to 0.01). We identified an association of increased incidence of CM and vitamin D insufficiency, as well as less favorable Breslow tumor depth with lower levels of vitamin D and the presence of vitamin D insufficiency.

Disparities in melanoma incidence and mortality in rural versus urban Michigan.

INTRODUCTION: We sought to identifying the possible existence of disparities between rural and urban residents of Michigan for the incidence by stage of disease and disease-specific mortality for cutaneous melanoma (CM). METHODS: Incidence rates for stage of disease and disease-specific mortality of cutaneous melanoma were calculated and controlled for gender, age, and area of residence from January 1, 2014, to December 31, 2018, from data collected form the Michigan Department of Health and Human Services and the Centers for Disease Control and Prevention. RESULTS: The incidence rates for CM were significantly higher in rural Michigan counties, from 2014-2018, for all patients, both age groups, both genders and all stages. Melanoma-specific mortality rates were also significantly higher for all patients, both age groups and both genders in rural Michigan counties. Using logistic regression analysis, while controlling for age and gender, rural Michigan counties continued to have a higher melanoma-specific morality rate during our study period (OR = 1.491; 95% CI, 1.27-1.74; p = <.001). CONCLUSION: We found significant disparities in the incidence rates and disease specific mortality for cutaneous melanoma in rural compared to urban Michigan from 2014-2018.

Physical Examination for the Detection of Pulmonary Hypertension: A Systematic Review.

We performed a systematic review to determine whether the physical examination can reliably assist in the diagnostic approach for patients suspected of having pulmonary hypertension (PH). Using dual extraction, two investigators independently searched PubMed, Ovid MEDLINE, Cochrane Library, and Embase for studies that compared physical examination findings with a right heart catheterization, from inception until July 10, 2021. We obtained data from four studies that evaluated physical examination findings in patients receiving a right heart catheterization to diagnose PH. Pooled diagnostic odds ratios (DOR) were calculated for right ventricular heave, a loud pulmonic component of the second heart sound (P2), jugular venous pressure (JVP) 3 cm above sternal angle, and a palpable P2. Three physical examination findings had DOR that supports the diagnosis of PH: the JVP > 3 cm above the sternal angle (5.90, 95% CI 2.57, 13.57), a loud P2 (2.91, 95% CI 1.38, 6.10), and a right ventricular heave (2.78, 95% CI 1.12, 6.89). The palpable P2 had a DOR less than one and was not able to be conclusive in diagnosing PH. Our systematic review found a small body of evidence supporting the use of physical examination tests in the diagnostic evaluation of pulmonary hypertension. The JVP > 3 cm above the sternal angle was the most accurate physical examination sign for the diagnosis of PH. Larger cohort studies using a combination of tests may shed more light on the role of the physical examination in the diagnosis and early detection of pulmonary hypertension.

Cancer Screening During the COVID-19 Pandemic: A Systematic Review and Meta-analysis.

The purpose of this study was to assess the impact of measures designed to mitigate the spread of coronavirus disease 2019 (COVID-19) on worldwide cancer screening. We systematically searched PubMed, Ovid MEDLINE, the Cochrane COVID-19 Study Register, ClinicalTrials.gov, and EMBASE without language restrictions for studies published between January 1, 2021, and February 10, 2021. Studies selected for full-text review contained data on patients screened for any type of cancer during the COVID-19 pandemic and comparison data from a time interval just prior to the pandemic. Data were obtained through dual extraction. All the included studies were assessed for quality and risk of bias. A meta-analysis was performed on 13 studies: 7 on screening mammography, 5 on colon cancer screening, and 3 on cervical cancer screening. Two of our studies reported on more than one type of cancer screening. The screening outcomes were reported as pooled incidence rate ratios using the inverse variance method and random effects models. All studies included in our meta-analysis reported the number of patients screened for cancer in defined time intervals before and during the COVID-19 pandemic. We found that the pooled incidence rate ratios were significantly lower for screening during the COVID-19 pandemic for breast cancer (0.63; 95% CI, 0.53 to 0.77; P<.001), colon cancer (0.11; 95% CI, 0.05 to 0.24; P<.001), and cervical cancer (0.10; 95% CI, 0.04 to 0.24; P<.001). These findings may add further morbidity and mortality to this public health crisis.

Impact of Biopsy Technique on Clinically Important Outcomes for Cutaneous Melanoma: A Systematic Review and Meta-analysis.

We performed a systematic review and meta-analysis to examine the relationship between the type of biopsy technique employed in the diagnosis of cutaneous melanoma and 4 clinically important outcomes: melanoma-specific mortality, all-cause mortality, Breslow tumor depth, or melanoma recurrence. Our database was obtained by searching PubMed, Ovid MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews, and the Cochrane Library from inception until December 6, 2019. Studies were identified that compared biopsy techniques used to diagnose cutaneous melanoma with any of our study outcomes. We included 7 observational studies for our meta-analysis after screening 3231 titles and abstracts. Pooled data identified a significantly higher all-cause mortality in the punch biopsy group (risk ratio [RR], 1.520; P=.02). A higher, but nonsignificant, rate of melanoma-specific mortality (RR, 1.96; P=.22) and melanoma recurrence (RR, 1.20; P=.186) was also found for the punch biopsy group. Breslow tumor thickness was not significantly lower for punch incision (standardized mean difference, -0.42; P=.27). We found limited evidence for differences in clinically important outcomes across the spectrum of the most common methods employed in clinical practice for the initial diagnosis of cutaneous melanoma. A small, but significant, increase (P=.02) in all-cause mortality with punch biopsies was not seen for the other outcomes and was most likely due to small sample sizes and demographic differences in the included studies and unlikely represents a clinically important outcome. Our findings support the use of existing clinical practice guidelines for evaluating pigmented lesions suspicious for cutaneous melanoma.

Correction: Physical examination in dyspnea.

On page 949 of the article, "Diagnostic value of the physical examination in patients with dyspnea" (Shellenberger RA, Balakrishnan B, Avula S, Ebel A, Shaik S. Cleve Clin J Med 2017; 84[12]:943-950), the terms "abdominojugular reflex" and "hepatojugular reflex" should have been "abdominojugular reflux" and "hepatojugular reflux." This error also occurred in Table 5 on that page.

Diagnostic value of the physical examination in patients with dyspnea.

We reviewed the evidence for the diagnostic accuracy of the physical examination in diagnosing pneumonia, pleural effusion, chronic obstructive pulmonary disease, and congestive heart failure in patients with dyspnea and found that the physical examination has reliable diagnostic accuracy for these common conditions.
