Research shows that there has been a substantial increase in substance use and abuse during the COVID-19 pandemic, and that substance use/abuse is a commonly reported way of coping with anxiety concerning COVID-19. Anxiety about COVID-19 is more than simply worry about infection. Research provides evidence of a COVID Stress Syndrome characterized by (1) worry about the dangers of COVID-19 and worry about coming into contact with coronavirus contaminated objects or surfaces, (2) worry about the personal socioeconomic impact of COVID-19, (3) xenophobic worries that foreigners are spreading COVID-19, (4) COVID-19-related traumatic stress symptoms (e.g., nightmares), and (5) COVID-19-related compulsive checking and reassurance-seeking. These form a network of interrelated nodes. Research also provides evidence of another constellation or "syndrome", characterized by (1) belief that one has robust physical health against COVID-19, (2) belief that the threat of COVID-19 has been exaggerated, and (3) disregard for social distancing. These also form a network of nodes known as a COVID-19 Disregard Syndrome. The present study, based on a population-representative sample of 3075 American and Canadian adults, sought to investigate how these syndromes are related to substance use and abuse. We found substantial COVID-19-related increases in alcohol and drug use. Network analyses indicated that although the two syndromes are negatively correlated with one another, they both have positive links to alcohol and drug abuse. More specifically, COVID-19-related traumatic stress symptoms and the tendency to disregard social distancing were both linked to substance abuse. Clinical and public health implications are discussed.
Obstructive sleep apnoea (OSA) is an important factor in the development and progression of heart failure (HF). The prevalence of OSA is higher in patients with HF than in the general population. We sought to test the hypothesis that OSA severity was predictive of ventricular function and cardiac injury [as assessed by high-sensitivity cardiac troponin I(hs-cTnI)].

A total of 60 patients were recruited after evaluation for sleep disturbances using the Jenkins Sleep Questionnaire (JSQ) and Epworth Sleepiness Scale (ESS). Subsequently, they underwent polysomnography thus confirming the diagnosis of OSA and were equally divided into three groups according to OSA severity grade. Following polysomnography, the next morning patients underwent venous blood sampling and echocardiography.

We observed a statistically significant association (P=0.009) between diastolic dysfunction grades and severity grades of OSA. All the three diastolic dysfunction variables E/A ratio, deceleration time and E/e' ratio had a signwith the notion of a vicious cycle of frequent apnoea's or hypoxemia and recurrent myocardial injury, which could increase the risk of heart failure especially diastolic dysfunction in OSA.
On Nov 17, 2020, WHO launched a global initiative to accelerate the elimination of cervical cancer through the implementation of HPV vaccination, cervical cancer screening and treatment for precancer and cancer. China has the largest burden of cervical cancer in the world, but only has a national cervical cancer screening program in rural areas since 2009. Here, we aimed to evaluate the effectiveness and cost-effectiveness of cervical cancer screening in urban China, using Shenzhen City as an example.

We use an extensively validated platform ('Policy1-Cervix'), calibrated to data from Shenzhen city and Guandong Province. We evaluated a range of strategies that have previously been implemented as pilot studies in China, or recommended as guidelines within China and globally, spanning primary HPV, cytology and co-testing strategies. We additionally considered alternate triaging methods, age ranges and screening intervals, resulting in 19 algorithms in total.

Of the 19 strategies considered, the most effecr 100,000 over the long term. 17-AAG In order to achieve rates below 4 per 100,000, the elimination threshold set by the World Health Organization, vaccination will likely also be necessary.Specific Learning Disability (SLD) is a neurodevelopmental disorder with significant problems in language processing, which are evident through difficulties in reading, writing, spelling, and mathematics. SLD was notified as a disability by the Government of India in 2016. Until then, it was primarily left to the discretion of the individual education boards to decide the assessment procedures and support measures for a child suspected to have SLD. However, with the enforcement of the Rights of Persons with Disabilities Act 2016 (RPWD Act), there is a legal binding to follow specific guidelines for assessment and certification mentioned in the RPWD Act. Nonetheless, there are issues inherent to the construct of SLD described in the diagnostic manuals and the current certification processes under the RPWD Act. In this context, this paper highlights the discrepancies in the requirements of the RPWD Act and the diagnostic criteria of the International Classification of Diseases -10 (ICD-10) and the Diagnostic and Statistical Manual- 5 (DSM-5) and draws implications for assessment and certification procedures which will affect the lives of millions of children in the Indian context. It also presents potential solutions and possible future directions related to the assessment of the SLD.There are some challenges and unmet needs in the early diagnosis and management of Sjögren's syndrome (SjS) such as prominent glandular dysfunction at diagnosis and long diagnostic delay. Those challenges are partly attributed to the lack of a good knowledge of the early stages of SjS, which is a major obstacle to delivering appropriate care to SjS patients. Findings from both clinical and experimental studies suggest the plausibility of a redefined SjS course consisting of 4 stages, which includes initiation stage, preclinical stage, asymptomatic SjS stage and overt SjS stage. More studies focusing on the pathological processes and changes during the early stages of SjS are needed. To enable early diagnosis and treatment for SjS, more useful biomarkers of the early stages of SjS need to be identified, and individuals at high risk of SjS development need to be identified. Appropriate screening can be performed to facilitate the early diagnosis of SjS among those high-risk individuals.
