As the global outbreak of COVID-19 continues to ravage the world, it is important to understand how frontline clinicians manage ventilatory support and the various limiting factors.

An online survey composed of 32 questions was developed and validated by an international expert panel.

Overall, 502 respondents from 40 countries across six continents completed the survey. The mean number (±SD) of ICU beds was 64 ± 84. The most popular initial diagnostic tools used for treatment initiation were arterial blood gas (48%) and clinical presentation (37.5%), while the national COVID-19 guidelines were the most used (61.2%). High flow nasal cannula (HFNC) (53.8%), non-invasive ventilation (NIV) (47%), and invasive mechanical ventilation (IMV) (92%) were mostly used for mild, moderate, and severe COVID-19 cases, respectively. However, only 38.8%, 56.6% and 82.9% of the respondents had standard protocols for HFNC, NIV, and IMV, respectively. The most frequently used modes of IMV and NIV were volume control (VC) (3us, with limited use of standard protocols and most frontline clinicians depending on isolated and varied management guidelines. We found increased staff workload, lack of trained staff and shortage of PPE to be the main limiting factors affecting global COVID-19 ventilatory support management.
The coronavirus COVID-19 has had very serious impacts on many aspects of people's lives worldwide, including the negative effect on the educational system that disturbed the normal functions of medical faculties. Understanding the experiences of medical faculty members will help to better prepare for making improvements in similar future crises. Moreover, to our extended knowledge, there is no study on e-learning in the field of medical university education in the Kingdom of Saudi Arabia. The aim of this qualitative study was to explore how online learning was applied at Taif University after the total transformation from traditional education to Blackboard during the COVID-19 crisis and how it can be improved.

The study used a descriptive qualitative study design. Staff from four medical colleges at Taif University, Saudi Arabia were invited to participate in a semi-structured interview. Eight Saudi lecturers participated, and data were analysed using thematic analysis.

This study revealed four themes Blackboard is professionally well designed; obstacles to the use of Blackboard; the need for Blackboard training; and student behavior through Blackboard.

The use of the Blackboard has its advantages and disadvantages, and the education sector needs to do more research to find out that issues and work to improve it.

Adverse maternal and child health outcomes due to adolescent pregnancy are central to public health research and practice. In addition, public health has emphasised that the care rendered by healthcare providers plays a pivotal role in the health and well-being of pregnant and parenting adolescents. Healthcare providers may differ in the ways they interpret adolescent pregnancy and parenting and consequently, this may have profound implications for healthcare decision making. The aim of this study was to explore the multiple perspectives of a diverse group of healthcare providers' delivering services and engaging with pregnant adolescents and adolescent mothers at a district hospital in Ugu, KwaZulu Natal, South Africa.

This descriptive qualitative study used semi-structured interviews (n=33). Healthcare providers rendering care to pregnant and parenting adolescents were recruited from the maternity, antenatal, paediatrics, psychology, dietetics, physiotherapy and social work departments, as well as from emental counselling and tailored services for pregnant adolescents and adolescent mothers are essential. When appropriately disseminated, the findings will assist relevant healthcare providers, administrators in healthcare institutions, policymakers, and officials of the Department of Health and the Department of Education in South Africa to address the lack of appropriate care for pregnant and parenting adolescents.
The study compares low-level laser therapy with topical medications for treating aphthous ulcers.

A search of articles in this systematic review was completed in six databases. Treatment and comparative groups comprised of patients subjected to laser therapy and topical medications, respectively. Two different treatment outcomes were considered; pain and size of the lesion. Risk of bias was assessed using the Revised Cochrane risk-of-bias tool for randomized trials.

From 109 articles, five randomized control trials fulfilled the selection criteria. The overall sample comprised of 98 males and 232 females, with a mean age of 32.4 years. The laser therapies in each included study had different active media and varying wavelengths. Topical medication used in the comparative group were triamcinolone acetonide, amlexanox, granofurin, and solcoseryl. Findings showed that patients who reported lower pain and decreased aphthous ulcer lesions were more in the laser therapy group than in the topical medication group.

Low-level laser therapy was better in treating aphthous ulcer lesions in comparison to topical medications, and all laser wavelengths in the included reports were seen to be effective. However, the results should be interpreted with caution, because no study demonstrated low-risk of bias in all the assessed domains.

Breast cancer is the most prominent form of cancer and the second leading cause of death in women behind lung cancer. The primary modes of treatment today include surgical excision (lumpectomy, mastectomy), radiation, chemoablation, anti-HER2/neu therapy, and/or hormone therapy. The severe side effects associated with these therapies suggest a minimally invasive therapy with fewer quality of life issues would be advantageous for treatment of this pervasive disease. Cryoablation has been used in the treatment of other cancers, including prostate, skin, and cervical, for decades and has been shown to be a successful minimally invasive therapeutic option. To this end, the use of cryotherapy for the treatment of breast cancer has increased over the last several years. Although successful, one of the challenges in cryoablation is management of cancer destruction in the periphery of the ice ball as the tissue within this outer margin may not experience ablative temperatures. In breast cancer, this is of concern dfor the treatment of breast cancer.Diabetes accelerates cancer cell proliferation and metastasis, particularly for cancers of the pancreas, liver, breast, colon, and skin. While pathways linking the 2 disease conditions have been explored extensively, there is a lack of information on whether there could be cytoarchitectural changes induced by glucose which predispose cancer cells to aggressive phenotypes. It was thus hypothesized that exposure to diabetes/high glucose alters the biomechanical and biophysical properties of cancer cells more than the normal cells, which aids in advancing the cancer. learn more For this study, atomic force microscopy indentation was used through microscale probing of multiple human breast cancer cells (MCF-7, MDA-MB-231), and human normal mammary epithelial cells (MCF-10A), under different levels of glycemic stress. These were used to study both benign and malignant breast tissue behaviors. Benign cells (MCF-10A) recorded higher Young's modulus values than malignant cells (MCF-7 and MDA-231) under normoglycemic conditions, which agrees with the current literature. Moreover, exposure to high glucose (for 48 hours) decreased Young's modulus in both benign and malignant cells, to the effect that the cancer cells showed a complete loss in elasticity with high glucose. This provides a possible insight into a link between glycemic stress and cytoskeletal strength. This work suggests that reducing glycemic stress in cancer patients and those at risk can prove beneficial in restoring normal cytoskeletal structure.
To assess the functional and refractive outcomes in hyperopia and presbyopia correction by clear lens exchange with the intraocular trifocal artificial lens (IOL) Acrysof IQ Panoptix implant at 1 year.

A number of 128 eyes (64 patients) underwent clear lens exchange with placement of the trifocal IOL Acrysof IQ Panoptix implant for hyperopia and presbyopia. Prior to the surgery the patients had a complete ocular examination. In all cases the artificial lens was implanted in the bag without any intraoperative complications. link2 Visual acuity (VA) at distance, intermediate and near and ocular refraction were evaluated at 4 weeks, 6 and 12 months postoperatively.

The mean age was 53.49 ±7.377 years old (range 40-73 years). As high as 51.57% of the patients were males and 48.43% were females. The mean achieved refraction was 0.26 ± 0.73D. Almost 60.93% of patients were within ±0.25D of the target refraction, with 82.03% eyes within ±0.50D of the planned correction. At 1 year after surgery, 96.45% of eyes had a isfaction with the outcomes of the surgery. Spectacle independence was obtained in 97.65% eyes.

The Acrysof Panoptix trifocal artificial lens offers a good vision at distance, intermediate and near, with a good quality of vision and refraction.

Telepsychiatry, a subset of telemedicine, has been increasingly studied to meet the growing demands for psychiatric care. link3 The utility of telepsychiatry is relevant now more than ever as the world endures the COVID-19 global pandemic. This paper describes the prior state and the changes that the COVID-19 outbreak brought to telepsychiatry in a selected group of Arab countries of the Middle East and North Africa (MENA) region.

We invited twelve early-career psychiatrists from different Arab nations to share information related to telepsychiatry in their respective countries before and during the COVID-19 pandemic. The information was collected using a semi-structured guide. This was complemented by a search for relevant articles in five search engines using terms such as "COVID-19," "telepsychiatry," and "Arab world".

Before the pandemic, digital mental health services were provided in several Arab countries, mainly through hotlines and messaging services. The COVID-19 pandemic has marked a major shift inultifactorial barriers. As affordable and attainable solutions cannot only rely on training and recruiting more psychiatrists, telepsychiatry would help meet the exceeding demands in the Arab world, particularly after the COVID-19 outbreak.Acne is a common skin disease that affect over 80% of adolescents. It is characterized by inflammation of the hair bulb and the attached sebaceous gland. To date, many strategies have been used to treat acne as a function of the disease severity. However, common treatments for acne seem to show several side effects, from local irritation to more serious collateral effects. The use of topical vesicular carriers able to deliver active compounds is currently considered as an excellent approach in the treatment of different skin diseases. Many results in the literature have proven that drug delivery systems are useful in overcoming the toxicity induced by common drug therapies, while maintaining their therapeutic efficacy. Starting from these assumptions, the authors reviewed drug delivery systems already realized for the topical treatment of acne, with a focus on their limitations and advantages over conventional treatment strategies. Although their exact mechanism of permeation is not often completely clear, deformable vesicles seem to be the best solution for obtaining a specific delivery of drugs into the deeper skin layers, with consequent increased local action and minimized collateral effects.
