AbstractFor many historical and contemporary experimental studies in marine biology, seawater carbonate chemistry remains a ghost factor, an uncontrolled, unmeasured, and often dynamic variable affecting experimental organisms or the treatments to which investigators subject them. We highlight how environmental variability, such as seasonal upwelling and biological respiration, drive variation in seawater carbonate chemistry that can influence laboratory experiments in unintended ways and introduce a signal consistent with ocean acidification. As the impacts of carbonate chemistry on biochemical pathways that underlie growth, development, reproduction, and behavior become better understood, the hidden effects of this previously overlooked variable need to be acknowledged. Here we bring this emerging challenge to the attention of the wider community of experimental biologists who rely on access to organisms and water from marine and estuarine laboratories and who may benefit from explicit considerations of a growing literature on the pervasive effects of aquatic carbonate chemistry changes.Coronavirus disease-2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has abruptly transformed the outlook of employer health benefits plans for 2020 and 2021. Containing the spread of the virus and facilitating care of those infected have quickly emerged as immediate priorities. Employers have adjusted health benefits coverage to make COVID-19 testing and treatment accessible and remove barriers to care in order to facilitate the containment of the disease. Employers also are introducing strategies focused on testing, surveillance, workplace modifications, and hygiene to keep workforces healthy and workplaces safe.

Such considerations include (1) return to work practices focused on mitigating the spread of COVID-19 through safety practices, testing and surveillance; and (2) anticipating the impact of COVID-19 on health benefits and costs (including adaptations in delivery of care, social and behavioral health needs, and managing interrupted care for chronic conditions).The single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) has been introduced in the past few years for the treatment of morbid obesity. SADI-S has shown good results in terms of long-term results and short-term complications. However, the management of patients undergoing SADI-S and suffering from a leak is a great challenge for surgeons. We present an extensive review of the currently available literature on the management of leak after SADI in morbid obese (MO) patients. We aim at providing objective information regarding the optimal management, including diagnosis, technical options for the different strategies that have been proposed, to facilitate the selection of the best individual approach for each MO patient.<br /><br /> This study evaluates the spectrum of visual impairment in stroke survivors.<br /><br /> The Impact of Visual Impairment after Stroke (IVIS) study is a multi-centre, acute stroke unit, prospective epidemiology study. Comprehensive visual examination was offered to all stroke survivors.<br /><br /> 1500 stroke admissions were recruited. 1204 stroke survivors had visual assessment. Reduced central vision was documented in 529, visual field loss in 308, ocular motility abnormalities in 533 stroke survivors, visual perception deficits in 59 stroke survivors and visual inattention in 315 stroke survivors. About half, regardless of visual impairment type, were visually asymptomatic. Recovery, whether full or partial, was best for central vision, ocular motility abnormalities and visual perception deficits (about 70% improvement) occurring over a mean follow-up period of 2-3 months.<br /><br /> Incidence of impaired central vision, visual field loss, ocular motility disorders and visual inattention was 29.4%, 24.8%, 39.3% and 26.2% respectivelyatic cases raise concerns for acute stroke units where robust specialist vision screening is not routine. Those with partial/no recovery require specialist follow-up and management whilst the wide range of abnormalities highlight the need for specialist visual assessment acutely.Implications for rehabilitationVisual impairment is a common consequence of stroke.Incidence of visual impairment is about 60%.Significant numbers of stroke survivors are visually asymptomatic, highlighting the need for standardised vision assessments.Many stroke survivors have persistent long-term visual impairment, necessitating referral and access to specialist eye care services.<br /><br /> Illness narratives are cultural artifacts that reflect the ways through which a certain culture perceives and constructs a given illness. Against this backdrop, the study explored the social construction of MS in Israeli society.<br /><br /> Thematic content analysis of all (70) illness narratives posted on the Israel MS Society's website between 2012-2018, was employed.<br /><br /> Five themes were identified in our analysis, according to chronological order (1) "Becoming ill" - consisted of framing MS as a sudden affliction or constructing MS as a gradual development. (2) "Negative changes" depicted MS as inflicting negative bodily changes and a disruption to the social order. The "happy ending" of the narratives pertained to (3) "adjustments" to MS and, (4) "never giving up" to MS. These were facilitated by embracing (5) "positive thinking and optimism."<br /><br /> MS is perceived in Israel as a form of "deviance" and as a biomedical phenomenon. Rehabilitation and healthcare staff, therefore, need to actively engage in interventionsollaborate with people with MS and disability advocates in order to reconstruct and shape policies and the planning of communities such that they address the socio-cultural barriers that people with MS face.Background The internet is a broadly preferred source of information both by patients and medical professionals. YouTube™ is a significant information source that may be a useful tool to inform the public, medical students, and residents, and may improve the learning experience if used adequately. In this study, we aimed to estimate the quality and accuracy of videos regarding Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) aired on YouTube, which is the most popular video platform of the online world. Materials and Methods We evaluated the first 50 videos, returned by the YouTube research engine, in reply to the "TOETVA" keyword. The popularity of the videos was assessed using the video power index (VPI). The educational quality, accuracy, and transparency of the content regarding TOETVA were estimated by using the DISCERN questionnaire score (DISCERNqs), Journal of American Medical Association benchmark criteria (JAMABC), and global quality score (GQSc). The technical quality was ranked through TOETVA Scoring System (TOETVA-SS) by a TOETVA practicioning endocrine surgeon.
