Potential for optimizing management of obesity in the secondary prevention of coronary heart disease.

Eur Heart J Qual Care Clin Outcomes 2021 Jul 27. Epub 2021 Jul 27.

Department of Medicine, Solna, Karolinska Institutet, FoU - Tema Hjärta och Kärl, S1:02, Karolinska Universitetssjukhuset/Solna, SE-171 76, Stockholm, Sweden.

Aims: Prevention guidelines have identified the management of obese patients as an important priority to reduce the burden of incident and recurrent cardiovascular disease. Still, studies have demonstrated that over 80% of patients with coronary heart disease (CHD) fail to achieve their weight target. Here, we describe advice received and actions reported by overweight CHD patients since being discharged from hospital and how weight changes relate to their risk profile. Read More

Tracking Pandemic Severity Using Data on the Age Structure of Mortality: Lessons From the 1918 Influenza Pandemic in Michigan.

Am J Public Health 2021 Jul;111(S2):S149-S155

Siddharth Chandra is with the Asian Studies Center and James Madison College at Michigan State University, East Lansing, with a courtesy appointment in the Department of Epidemiology and Biostatistics. Julia Christensen is with James Madison College at Michigan State University, East Lansing.

To test whether distortions in the age structure of mortality during the 1918 influenza pandemic in Michigan tracked the severity of the pandemic. We calculated monthly excess deaths during the period of 1918 to 1920 by using monthly data on all-cause deaths for the period of 1912 to 1920 in Michigan. Next, we measured distortions in the age distribution of deaths by using the Kuiper goodness-of-fit test statistic comparing the monthly distribution of deaths by age in 1918 to 1920 with the baseline distribution for the corresponding month for 1912 to 1917.

Minimally invasive robotic cervicothoracic fusion: a case report and review of literature.

AME Case Rep 2021 25;5:24. Epub 2021 Jul 25.

Department of Neurosurgery, University of California San Diego School of Medicine, San Diego, CA, USA.

Minimally invasive surgery (MIS) of the posterior cervical spine with robotic assistance has recently emerged to treat degenerative disc disease. Robotic arms and 3D neuronavigation with preoperatively planned placement are used to achieve real-time intraoperative guidance, reducing screw malposition through increased accuracy and stability. This results in decreased blood loss, postoperative pain, and quicker recovery time compared to other techniques. Read More

Comparison of fatigue and fatigability correlates in Korean breast cancer survivors and differences in associations with anxiety, depression, sleep disturbance, and endocrine symptoms: a randomized controlled trial.

BMC Cancer 2021 Jul 26;21(1):855. Epub 2021 Jul 26.

College of Nursing, Mo-Im Kim Nursing Research Institute, Yonsei University, Seoul, Korea, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea.

Background: Fatigue is one of the most common and burdensome symptoms experienced by cancer patients. In interventions intended to reduce fatigue in such patients, fatigability, or perception of fatigue contextualized to activities of fixed intensity and duration, may also be measured. This study investigated the effects of a 15-month intervention on fatigue and fatigability in breast cancer survivors (BCS); explored the fatigue-fatigability relationship; and evaluated the impacts of fatigue and fatigability on anxiety, depression, sleep disturbance, and endocrine symptoms.

Boosting the input: 9-month-olds' sensitivity to low-frequency phonotactic patterns in novel wordforms.

Infancy 2021 Jul 23. Epub 2021 Jul 23.

Department of Psychology, University of Calgary, Calgary, Alberta, Canada.

To learn their first words, infants must attend to a variety of cues that signal word boundaries. One such cue infants might use is the language-specific phonotactics to track legal combinations and positions of segments within a word. Studies have demonstrated that, when tested across statistically high and low phonotactics, infants repeatedly reject the low-frequency wordforms. Read More

LDLR expression in the cochlea suggests a role in endolymph homeostasis and cochlear amplification.

Hear Res 2021 Jul 15;409:108311. Epub 2021 Jul 15.

GIGA-Neurosciences, Unit of Cell and Tissue Biology, University of Liège, C.H.U. B36, B-4000 Liège, Belgium. Electronic address:

There is now growing evidence that hypercholesterolemia and high serum levels of low-density lipoproteins (LDL) predispose to sensorineural hearing loss. Circulating LDL-cholesterol is delivered to peripheral tissues via LDL receptor (LDLR) -mediated endocytosis. Recently, it has been shown that LDLR gene polymorphisms are associated with higher susceptibility to sudden deafness. Read More

Cross-sectional and longitudinal evaluation of cannabidiol (CBD) product use and health among people with epilepsy.

Epilepsy Behav 2021 Jul 23;122:108205. Epub 2021 Jul 23.

Johns Hopkins University School of Medicine, Department of Psychiatry and Behavioral Sciences, Baltimore, MD, USA.

Recent approval of Epidiolex® (pharmaceutical cannabidiol/CBD) for the treatment of Lennox Gastaut syndrome (LGS) and Dravet syndrome highlights a therapeutic efficacy of CBD in the treatment of epilepsy. However, a large number of patients with epilepsy elect to use alternative artisanal CBD products due to cost or access constraints. Despite widespread availability and variety of these artisanal CBD products, studies evaluating their safety or efficacy are rare, making conclusions about clinical utility uncertain. Read More

Feasibility and impact of near-point-of-care integrated TB/HIV testing in Malawi and Zimbabwe.

AIDS 2021 Jul 22. Epub 2021 Jul 22.

Clinton Health Access Initiative, Boston, USA Clinton Health Access Initiative, Harare, Zimbabwe Clinton Health Access Initiative, Lilongwe, Malawi Ministry of Health and Child Care, Harare, Zimbabwe Ministry of Health and Population, Lilongwe, Malawi. Authors contributed equally.

Objectives: Near-point-of-care (POC) testing for early infant diagnosis (EID) and viral load (VL) expedites clinical action and improves outcomes, but requires capital investment. We assessed whether excess capacity on existing near-POC devices used for TB diagnosis could be leveraged to increase near-POC HIV molecular testing, termed integrated testing, without compromising TB services.
