Prostate cancer incidence in men with prostate-specific antigen below 3 ng/mL: The Finnish Randomized Study of Screening for Prostate Cancer

Prostate-specific antigen (PSA)-based screening for prostate cancer (PCa) can reduce PCa mortality, but also involves overdetection of low-risk disease with potential adverse effects. We evaluated PCa incidence among men with PSA below 3 ng/mL and no PCa diagnosis at the first screening round of the Finnish Randomized Study of Screening for PCa. Follow-up started at the first screening attendance and ended at PCa diagnosis, emigration, death or the common closing date (December 2016), whichever came first. Cox regression analysis was used to estimate hazard ratios and their confidence intervals (CI). Among men with PSA <3 ng/mL, cumulative PCa incidence was 9.1% after 17.6 years median follow-up. Cumulative incidence was 3.6% among men with baseline PSA 0 to 0.99 ng/mL, 11.5% in those with PSA 1.0 to 1.99 ng/mL and 25.7% among men with PSA 2 to 2.99 ng/mL (hazard ratio 9.0, 95% CI: 7.9-10.2 for the latter). The differences by PSA level were most striking for low-risk disease based on Gleason score and EAU risk group. PSA values <1 ng/mL indicate a very low 20-year risk, while at PSA 2 to 2.99 ng/mL risks are materially higher, with 4- to 5-fold risk for aggressive disease. Using risk-stratification and appropriate rescreening intervals will reduce screening intensity and overdetection. Using cumulative incidence of clinically significant PCa (csPCa) as the criterion, rescreening intervals could range from approximately 3 years for men with initial PSA 2 to 2.99 ng/mL, 6 years for men with PSA 1 to 1.99 ng/mL to 10 years for men with PSA <1 ng/mL.

Twelve tips for teaching a comprehensive disease-focused course with a global perspective: A sickle cell disease example

A disease-focused course entitled “Understanding Sickle Cell Disease: A Biopsychosocial Approach” addressed the complex nature of SCD using patient-centered, global and interdisciplinary approaches. Sickle cell disease (SCD) is a rare inherited blood disorder that requires multidisciplinary care. Worldwide 20–25 million individuals have SCD, which is associated with a shortened lifespan due to many medical complications and social and behavioral health challenges. Health care professionals often have limited knowledge of SCD as they typically learn about it within the context of their own disciplines. This article provides twelve tips for educators that can be used to develop a similar course on any disease, with considerations for both low- and high-resource countries. The tips were devised from personal experience and available literature. Through these twelve tips, we provide a practical framework for increasing knowledge of complex diseases like SCD using a comprehensive elective course.     

Talon cusp in the temporary dentition of a patient with Kabuki syndrome: Case report with a two‐year follow‐up

The presence of dental abnormalities in the same individual may be related to syndromic cases and occur through associated systemic changes. Kabuki syndrome presents well‐defined systemic changes, but its clinical characteristics related to the oral cavity have not been fully explained. This study aimed to report the dental changes in a child diagnosed with Kabuki syndrome. A male brown patient aged 2 years and 7 months, accompanied by his mother to the dental visit, they main complaint was the presented of an additional tooth behind upper right central incisor. Anamnesis, intra‐ and extraoral examinations, and dental X‐rays were performed, revealing a talon cusp. Considering the dental clinical findings, the patient was referred to a medical geneticist who additionally requested cardiological and genetic examinations, which established the Kabuki syndrome. The caregivers were advised that the talon cusp would not cause any injury to the natural exfoliation of the tooth and that oral hygiene should be performed carefully. Abnormalities in the oral cavity and developmental delay may be associated with a potential undiagnosed syndrome. The medical evaluation becomes decisive for investigation, diagnosis, and final conduct of the case.     

Narrative review of the psychometric properties of language tests used in anomia treatment for primary progressive aphasia (PPA)

Background: Primary progressive aphasia (PPA) is a neurodegenerative dementia in which language decline is the first and most prominent symptom. Among several interventions for PPA, language rehabilitation has been the most frequently used.

Aims: This narrative review aimed to evaluate existing standardised language tests used in the assessment of PPA, in order to determine whether they are appropriate and psychometrically adequate to detect change over time in the treatment of anomia.

Main Contribution: The present findings highlight the scarcity of psychometrically robust instruments used to measure therapy-induced gains in PPA. Additionally, most of these instruments were not validated for use with the PPA population, which consequently might bias the results. There is a need for population-based norms for existing instruments.

Conclusions: The accurate assessment of lexico-semantic deficits in PPA should rely on objective, reliable, valid, and responsive outcome measures. Psychometric studies are needed to evaluate and eventually improve the quality of language tests used in clinical practice.     

Optimization of infusional calcium gluconate for prevention of hypocalcemic reactions during therapeutic plasma exchange

We sought to optimize direct intravenous infusion of calcium gluconate (CaGlu) for maintaining plasma ionized calcium concentration ([Ca²⁺]) and preventing hypocalcemic reactions during 34 consecutive 1-volume therapeutic plasma exchanges (TPEs) in eight patients. CaGlu, 2 g in 50 mL of 0.9% NaCl, was prepared by our hospital pharmacy and infused at either 1.0 or 1.6 g/h during alternate TPE. Plasma [Ca²⁺] was monitored at intervals of 20 to 30 minutes. At 1 g/h of CaGlu, plasma [Ca²⁺] fell by 8.35% after 40 to 50 minutes and then plateaued. At 1.6 g/h of CaGlu, plasma [Ca²⁺] fell by 6% after 20 to 30 minutes and then plateaued. The difference at 40 to 50 minutes was significant (P = .015). Hypocalcemic reactions were noted in three patients during 5 of 17 TPE at 1.0 g/h (all after 40 to 60 minutes) but 0 of 17 TPE at 1.6 g/h (P = .044). CaGlu at 1.6 g/h stabilized plasma [Ca²⁺] and appears to prevent hypocalcemic reactions during TPE.     

Exercise Intolerance in Patients With Heart Failure: JACC State-of-the-Art Review

Exercise intolerance is the cardinal symptom of heart failure (HF) and is of crucial relevance, because it is associated with a poor quality of life and increased mortality. While impaired cardiac reserve is considered to be central in HF, reduced exercise and functional capacity are the result of key patient characteristics and multisystem dysfunction, including aging, impaired pulmonary reserve, as well as peripheral and respiratory skeletal muscle dysfunction. We herein review the different modalities to quantify exercise intolerance, the pathophysiology of HF, and comorbid conditions as they lead to reductions in exercise and functional capacity, highlighting the fact that distinct causes may coexist and variably contribute to exercise intolerance in patients with HF.
