Diagnosis and treatment of refractory pituitary adenomas: a narrative review.

Gland Surg 2021 Apr;10(4):1499-1507

Chinese Pituitary Specialists Congress, Beijing, China.

Although aggressive pituitary adenomas (PAs) have been proposed and widely discussed for more than a decade, there is no general agreement regarding their definition, diagnosis or management. As one of the largest pituitary centers in China, we have diagnosed and treated more than fifty cases of aggressive PA and 3 pituitary carcinomas in the past 5 years and proposed a new term, i.e. Read More

Impact of modification to DSM-5 criterion A for hypomania/mania in newly diagnosed bipolar patients: findings from the prospective BIO study.

Int J Bipolar Disord 2021 May 3;9(1):14. Epub 2021 May 3.

Copenhagen Affective Disorders Research Centre (CADIC), Psychiatric Centre Copenhagen, Department O, 6233, Rigshospitalet, Blegdamsvej 9, 2100, Copenhagen, Denmark.

Background: DSM-IV states that criterion A for diagnosing hypomania/mania is mood change. The revised DSM-5 now states that increased energy or activity must be present alongside mood changes to diagnose hypomania/mania, thus raising energy/activity to criterion A. We set out to investigate how the change in criterion A affects the diagnosis of hypomanic/manic visits in patients with a newly diagnosed bipolar disorder. Read More

Adaptive sample size determination for the development of clinical prediction models.

Diagn Progn Res 2021 Mar 22;5(1). Epub 2021 Mar 22.

Department of Development & Regeneration, KU Leuven, Leuven, Belgium.

Background: We suggest an adaptive sample size calculation method for developing clinical prediction models, in which model performance is monitored sequentially as new data comes in.

Methods: We illustrate the approach using data for the diagnosis of ovarian cancer (n = 5914, 33% event fraction) and obstructive coronary artery disease (CAD; n = 4888, 44% event fraction). We used logistic regression to develop a prediction model consisting only of a priori selected predictors and assumed linear relations for continuous predictors. Read More

Implementation and Evolution of Mitigation Measures, Testing, and Contact Tracing in the National Football League, August 9-November 21, 2020.

MMWR Morb Mortal Wkly Rep 2021 Jan 29;70(4):130-135. Epub 2021 Jan 29.

The National Football League (NFL) and the NFL Players Association (NFLPA) began the 2020 football season in July, implementing extensive mitigation and surveillance measures in facilities and during travel and gameplay. Mitigation protocols* were evaluated and modified based on data from routine reverse transcription-polymerase chain reaction (RT-PCR) tests for SARS-CoV-2, the virus that causes coronavirus 2019 (COVID-19); proximity tracking devices; and detailed interviews. Midseason, transmission was observed in persons who had cumulative interactions of <15 minutes' duration, leading to a revised definition of high-risk contacts that required consideration of mask use, setting and room ventilation in addition to proximity and duration of interaction.

[Proposals for the diagnosis and treatment of andrologic diseases during the novel coronavirus pneumonia epidemic].

Zhonghua Nan Ke Xue 2020 Mar;26(3):200-204

Department of Andrology, The First Hospital of Sun Yat-sen University, Guangzhou, Guangdong 510080, China.

In December, 2019, several cases of novel coronavirus pneumonia (NCP) were reported in Wuhan, Hubei. Since then, more and more NCP cases, confirmed or suspected, have been found in China and other parts of the world, and the virus is now showing a tendency towards a wider spread. During the NCP epidemic, all medical workers are confronted with special challenges in the diagnosis and treatment of various diseases and required of even more accurate therapeutic protocols as well as stricter observation of the principles for the prevention and control of NCP.

Predementia constructs: Mild cognitive impairment or mild neurocognitive disorder? A narrative review.

Int J Geriatr Psychiatry 2020 Nov 26. Epub 2020 Nov 26.

Research Institute (Imas12), University Hospital "12 de Octubre", Madrid, Spain.

Background: Predementia is a heuristic umbrella concept to classify older adults with cognitive impairment who do not suffer dementia. Many diagnostic entities have been proposed to address this concept, but most of them have not had widespread acceptance.

Endonasal endoscopic surgery for sinonasal squamous cell carcinoma from an oncological perspective.

Auris Nasus Larynx 2021 Feb 4;48(1):41-49. Epub 2020 Dec 4.

International Head and Neck Scientific Group, Padua, Italy.

Endonasal endoscopic surgery (EES) has been applied to the management of sinonasal (SN) tumors based on recent advances in endoscopic surgical techniques and technologies over the past three decades. EES has been mainly indicated for benign tumors and less aggressive malignant tumors. Notwithstanding this, EES has been gradually adopted for squamous cell carcinoma (SCC), which is the most common histology among SN malignancies. Read More

Interpretation of serial interferon-gamma test results to measure new tuberculosis infection among household contacts in Zambia and South Africa.

BMC Infect Dis 2020 Oct 15;20(1):760. Epub 2020 Oct 15.

Department of Infectious Disease Epidemiology, London School of Hygiene and Tropical Medicine, London, UK.

Background: A more stringent QuantiFERON-TB Gold In-Tube (QFT) conversion (from negative to positive) definition has been proposed to allow more definite detection of recent tuberculosis (TB) infection. We explored alternative conversion definitions to assist the interpretation of serial QFT results and estimate incidence of TB infection in a large cohort study.

Methods: We used QFT serial results from TB household contacts aged ≥15 years, collected at baseline and during two follow-up visits (2006-2011) as part of a cohort study in 24 communities in Zambia and South Africa (SA). Read More

Early Prediction of Malignant Cerebellar Edema in Posterior Circulation Stroke Using Quantitative Lesion Water Uptake.

Neurosurgery 2021 02;88(3):531-537

Department of Diagnostic and Interventional Neuroradiology, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Background: Malignant cerebellar edema (MCE) is a life-threatening complication of ischemic posterior circulation stroke that requires timely diagnosis and management. Yet, there is no established imaging biomarker that may serve as predictor of MCE. Early edematous water uptake can be determined using quantitative lesion water uptake, but this biomarker has only been applied in anterior circulation strokes. Read More

Adrenal Venous Sampling-Guided Adrenalectomy Rates in Primary Aldosteronism: Results of an International Cohort (AVSTAT).

J Clin Endocrinol Metab 2021 Mar;106(3):e1400-e1407

Division of Diabetes and Endocrinology, National International Center for Global Health and Medicine, Tokyo, Japan.

Context: Adrenal venous sampling (AVS) is the current criterion standard lateralization technique in primary aldosteronism (PA). Japanese registry data found that 30% of patients with unilateral PA did not undergo adrenalectomy, but the reasons for this and whether the same pattern is seen internationally are unknown.

Late Diagnosis of Infants with PCD and Neonatal Respiratory Distress.

J Clin Med 2020 Sep 4;9(9). Epub 2020 Sep 4.

Institute of Social and Preventive Medicine, University of Bern, 3012 Bern, Switzerland.

Neonatal respiratory distress (NRD) is common among infants with primary ciliary dyskinesia (PCD), but we do not know whether affected neonates receive a timely diagnosis. We used data from the international PCD cohort and assessed the proportion of patients with PCD who had a history of NRD and their age at diagnosis, stratifying by presence of laterality defects. First we analyzed data from all participants diagnosed after 2000, followed by individuals from a subgroup diagnosed using stricter criteria. Read More
