Home-based initiatives for acute management of COVID-19 patients needing oxygen: differences across The Netherlands.

OBJECTIVE: During the COVID-19 pandemic new collaborative-care initiatives were developed for treating and monitoring COVID-19 patients with oxygen at home. Aim was to provide a structured overview focused on differences and similarities of initiatives of acute home-based management in the Netherlands. METHODS: Initiatives were eligible for evaluation if (i) COVID-19 patients received oxygen treatment at home; (ii) patients received structured remote monitoring; (iii) it was not an 'early hospital discharge' program; (iv) at least one patient was included. Protocols were screened, and additional information was obtained from involved physicians. Design choices were categorised into: eligible patient group, organization medical care, remote monitoring, nursing care, and devices used. RESULTS: Nine initiatives were screened for eligibility; five were included. Three initiatives included low-risk patients and two were designed specifically for frail patients. Emergency department (ED) visit for an initial diagnostic work-up and evaluation was mandatory in three initiatives before starting home management. Medical responsibility was either assigned to the general practitioner or hospital specialist, most often pulmonologist or internist. Pulse-oximetry was used in all initiatives, with additional monitoring of heart rate and respiratory rate in three initiatives. Remote monitoring staff's qualification and authority varied, and organization and logistics were covered by persons with various backgrounds. All initiatives offered remote monitoring via an application, two also offered a paper diary option. CONCLUSIONS: We observed differences in the organization of interprofessional collaboration for acute home management of hypoxemic COVID-19 patients. All initiatives used pulse-oximetry and an app for remote monitoring. Our overview may be of help to healthcare providers and organizations to set up and implement similar acute home management initiatives for critical episodes of COVID-19 (or other acute disorders) that would otherwise require hospital care.

The Psychosocial Impact of the COVID-19 Pandemic on Families of Children With Cancer in the Low-income Setting.

The coronavirus disease 2019 (COVID-19) pandemic has had a profound effect on families' psychosocial well-being worldwide. This study aimed to investigate the pandemic's impact on families of children with cancer in a low-income setting in Syria. The study conducted a cross-sectional survey of 50 families of children with cancer receiving treatment at a nongovernmental organization-based pediatric oncology unit in Syria. The survey used the Corona Anxiety Scale (CAS) to assess the pandemic's impact on families' anxiety, and other items to evaluate the financial toxicity of the strict measures implemented during the pandemic's first months. The study's results revealed that the COVID-19 pandemic significantly negatively impacted the psychosocial well-being of families of children with cancer in Syria. Specifically, 22% of families reported a major increase in anxiety levels (CAS of >9), and the majority of families (84%) reported excessive indirect financial costs, including travel and living expenses. The study emphasizes the significant social and psychological impact of the COVID-19 pandemic on families of children with cancer in Syria, highlighting the need for additional psychosocial interventions to mitigate future global health crises or pandemics' impact on this vulnerable population. The interventions should prioritize promoting resilience and adaptive coping strategies.

SMPD4 regulates mitotic nuclear envelope dynamics and its loss causes microcephaly and diabetes.

Biallelic loss-of-function variants in SMPD4 cause a rare and severe neurodevelopmental disorder with progressive congenital microcephaly and early death. SMPD4 encodes a sphingomyelinase that hydrolyses sphingomyelin into ceramide at neutral pH and can thereby affect membrane lipid homeostasis. SMPD4 localizes to the membranes of the endoplasmic reticulum and nuclear envelope and interacts with nuclear pore complexes (NPC). We refine the clinical phenotype of loss-of-function SMPD4 variants by describing five individuals from three unrelated families with longitudinal data due to prolonged survival. All individuals surviving beyond infancy developed insulin-dependent diabetes, besides presenting with a severe neurodevelopmental disorder and microcephaly, making diabetes one of the most frequent age-dependent non-cerebral abnormalities. We studied the function of SMPD4 at the cellular and organ levels. Knock-down of SMPD4 in human neural stem cells causes reduced proliferation rates and prolonged mitosis. Moreover, SMPD4 depletion results in abnormal nuclear envelope breakdown and reassembly during mitosis and decreased post-mitotic NPC insertion. Fibroblasts from affected individuals show deficient SMPD4-specific neutral sphingomyelinase activity, without changing (sub)cellular lipidome fractions, which suggests a local function of SMPD4 on the nuclear envelope. In embryonic mouse brain, knockdown of Smpd4 impairs cortical progenitor proliferation and induces premature differentiation by altering the balance between neurogenic and proliferative progenitor cell divisions. We hypothesize that, in individuals with SMPD4-related disease, nuclear envelope bending, which is needed to insert NPCs in the nuclear envelope, is impaired in the absence of SMPD4 and interferes with cerebral corticogenesis and survival of pancreatic beta cells.

Intermediate-term Visual Outcomes and Complications of Type 1 Boston Keratoprosthesis With and Without Glaucoma Surgery.

PURPOSE: Glaucoma is a cause of comorbidity in patients receiving the Boston keratoprosthesis (KPro). The aim of this study was to report the outcomes of the Boston KPro with or without glaucoma surgery. METHODS: This was a retrospective single-center cohort study. Patients who underwent Boston KPro from March 2009 to February 2019 were included. One eye per patient (the first surgery) was included in this study. Patients were classified into 2 groups: KPro only (group 1) and KPro with any form of glaucoma procedure (group 2). Main outcome measures were Best-corrected visual acuity (BCVA), functional success (BCVA 20/200 or better), anatomical success (retention of KPro at the last follow-up), and complications. RESULTS: Seventy-one eyes were included: 27 eyes (38%) in group 1 and 44 (62%) in group 2. There was no statistically significant difference in BCVA between groups 1 and 2 at each time point. Of the eyes in group 1, 11% lost light perception vision and 4.5% in group 2 ( P = 0.293). There was no difference in anatomical success with 70% in group 1 and 77% in group 2 ( P = 0.703) at the last follow-up, with a median failure time of 18 months. The functional success was 48% for group 1 and 50% for group 2 ( P = 0.541). CONCLUSIONS: Eyes undergoing KPro with glaucoma surgery before or at the same time carry a similar functional and anatomical success to eyes without glaucoma surgery.

Quarantine-related traumatic stress, views, and experiences during the first wave of Coronavirus pandemic: A mixed-methods study among adults in Saudi Arabia.

PURPOSE: Mental health is a significant problem following exposure to a traumatic event. This study aimed to examine quarantine-related experiences, traumatic stress, and coping strategies among adults quarantined in Saudi Arabia due to coronavirus disease 2019 (COVID-19) exposure or travel history. METHODS: Individuals aged ≥ 18 years who were quarantined in Saudi Arabia due to COVID-19 exposure or travel history were included. We used a sequential mixed methods design, using an online survey followed by in-depth individual telephonic interviews. The Impact of Event Scale-Revised (IES-R) was used to measure post-traumatic stress disorder (PTSD) symptoms after the quarantine. To identify factors associated with significant symptoms (IES-R score ≥ 33), prevalence ratios (PR) with 95% confidence intervals were computed using Poisson regression with robust error variance. In the next phase, a subset of the participants (n = 26) were interviewed to elicit their quarantine-related experiences and coping responses. Major themes and subthemes were identified. RESULTS: Of the 111 adults who completed the survey, 32 (28.8% [95% CI, 21.1-38.0%]) had significant PTSD symptoms (IES-R score ≥ 33) and 27 (24.3% [95% CI, 17.2-33.3%]) had severe symptoms (IES-R score > 37). Marital status was the only variable that was significantly associated with significant PTSD symptoms (P = 0.028). Significant symptoms were twice as prevalent in married adults than among other marital groups (PR 2.00, 95% CI, 1.08-3.72). Participants reported negative emotions such as overwhelming fear, helplessness, anxiety, and disgust. Participants utilized both problem-centered coping (e.g., use of social support) and emotion-centered coping (e.g., use of positive diversionary activities) during the quarantine period. CONCLUSION: PTSD symptoms were present in one out of every four quarantined persons. The quarantine experience is viewed negatively. These findings highlight the need for increased awareness about stress-related disorders among quarantined individuals. Efforts are needed to detect and manage these symptoms early while making the quarantine experience more satisfying for the involved individuals and groups.

Assessing patient cosmetic satisfaction after glaucoma drainage device surgery for different patch grafts.

BACKGROUND: The use of a tissue patch graft is common practice with a glaucoma drainage device (GDD). Patch grafts can be visible in the palpebral fissure and may be cosmetically displeasing for some patients. The aim of this study was to report the cosmetic satisfaction of pericardial, scleral, and corneal patch grafts related to superior GDD surgery. METHODS: Baseline clinical data were collected for consecutive patients with glaucoma operated between 2014 and 2019 at two tertiary eye care institutions (for superiorly-placed) Ahmad glaucoma valve implant using sclera, cornea and pericardium patch graft. A patient questionnaire that contained 4 concise questions, with a Likert-scale grading relating to cosmetic satisfaction was administered by a telephone-based interview. Responses and scores for each question were compared across patients who received the three different types of graft. A binominal logistic regression analysis was used to assess the effects of age, gender, type of graft, number of previous ocular surgeries, and final visual acuity to explain differences. RESULTS: We included 92 patients who met our inclusion criteria (24 patients received a corneal patch graft, 30 who received sclera and 38 who received pericardium). The mean (±SD) age was 50 (±17.5) years, and the average follow up was 20.7 (± 18.6) months. Regardless of the type of patch graft, most (67-84%) of patients were satisfied with the appearance of their eyes. Patients who received cornea or sclera were more likely to report that their eye looked 'abnormal' by others. Younger age was significantly associated with the response to this question. CONCLUSION: Patients are generally satisfied with the appearance of their eye following GDD surgery with each of the patch grafts for superiorly-placed GDDs. Younger patients with cornea or sclera were more likely to report that their eyes looked abnormal.

Perception of Ophthalmologists of COVID-19 Using the Health Belief Model.

Purpose To assess ophthalmologists' preparedness in such a critical period in the history of pandemics, a logical socio-psychological framework assessment using the health belief model (HBM) is essential to evaluate their risk perception, their willingness to actively participate in engaging in protective health behavior and acknowledge its benefits, and their capability to perform adequate successful methods for limiting the spread of coronavirus disease 2019 (COVID-19) and overcome the barriers they might encounter while implementing such precautions. Methods A cross-sectional study conducted at King Khaled Eye Specialist Hospital using a questionnaire-based (HBM) was distributed to 135 ophthalmologists in the institute to evaluate their risk perception of COVID-19 and determine which components of the HBM contribute to preventive health behavior related to the COVID-19 infection. Results The questionnaire had a reasonable response rate (79.3%, 107 ophthalmologists, including 48 consultants, 51 fellows, and 36 residents). The study demonstrated that this model is useful and mapped how several components were significantly correlated to actions. Most significantly, perceived susceptibility was the most important predictor of action. The second most important determinant of action was the perceived benefit. Conclusion Pandemics such as COVID-19 are likely to happen again in the future. Explicit attention to factors influencing motivation such as threat perception to adopt appropriate health-related behavior to limit the spread of communicable diseases is necessary. This study has successfully represented preparedness and risk behavior perception of ophthalmologists of the novel COVID-19 pandemic in one of the largest tertiary eye hospitals in the Middle East using the Health Belief Model.

Effect of Bandage Contact Lens Exchange on Pain and Healing After Photorefractive Keratectomy-A Randomized Control Trial.

OBJECTIVE: To evaluate the corneal re-epithelialization and patient-perceived pain after bandage contact lens (BCL) exchange on day one, after photorefractive keratectomy (PRK). METHODS: A randomized controlled trial, of all patients who underwent bilateral transepithelial-PRK (trans-PRK) or bilateral alcohol debridement and PRK (A-PRK), between March and October 2019. One eye of each patient was randomly assigned to BCL exchange on the first postoperative day (exchange group) and the BCL was not exchanged in the fellow eye (control group). Patients were evaluated daily until healing was complete. At each visit, the corneal epithelial defect was measured, and a questionnaire was used to assess pain, photophobia, and excessive tearing. P<0.05 was statistically significant. RESULTS: The study sample was comprised of 56 patients (mean age 27.2±5.7 years). Trans-PRK was performed in 20 (34.5%) and A-PRK in 36 (64.3%) patients. At day 3, 40 (71.4%) eyes of the exchange group healed completely compared with 38 (67.9%) eyes of the control group (P=0.5). At day-1 follow-up, the pain score was 1.87±1.4 in the exchange group and 2.29±1.3 in the control group (P=0.009). The mean pain score was 1.58±1.4 among patients who underwent A-PRK and 2.35±1.2 among patients operated by trans-PRK (P=0.04). CONCLUSION: The epithelial healing did not vary when BCL was exchanged one day after refractive surgery. However, postoperative pain score after PRK was lower at day 1, when the BCL was exchanged. Compared with A-PRK, trans-PRK group demonstrated a higher pain score in the early postoperative phase.

Incidence and outcome of suprachoroidal hemorrhage associated with pediatric glaucoma surgery.

PURPOSE: To report the incidence and outcomes of suprachoroidal hemorrhage (SCH) associated with pediatric glaucoma surgery. METHOD: The medical records of pediatric patients (<18 years of age) who had undergone glaucoma surgery and developed SCH from June 2014 to September 2017 were reviewed retrospectively. In all cases, the SCH was suspected clinically and was confirmed by B-scan ultrasound. Baseline characteristics, intraoperative details (including surgery type), and subsequent and final outcomes were extracted from the records. RESULTS: Of 2,656 glaucoma surgeries during the study period, 17 cases of SCH were documented, for an overall incidence of 0.64%. Of the 17 cases, 16 occurred postoperatively, and 1 was noted intraoperatively. By surgery type, the incidence of SCH was highest for trabeculectomy (4/121), followed by glaucoma drainage device surgery (6/463), deep sclerectomy (6/851), and transcleral cyclophotocoagulation (1/542). Four children had received prior transcleral cyclophotocoagulation, and 5 of the children were aphakic at the time of the glaucoma surgery. At a mean final follow-up of 1.71 ± 1.08 years), visual acuity in the affected eye was 20/50 or better in 3 children, between 20/50 and 20/200 in 5 children, and counting fingers or worse in 9 children. CONCLUSIONS: In our study cohort, the overall incidence of SCH associated with glaucoma surgery was 0.64%. Further study of risk factors for SCH associated with glaucoma surgery in children is needed.

Knowledge and attitude towards hazardous effects of laser pointers among attendees of football matches in Riyadh, Saudi Arabia.

PURPOSE: There has been a recent increase in accidental retinal injuries due to the careless use of handheld laser devices. The scenarios under which these incidents occur suggest a lack of awareness of the sight-threatening hazards of some handheld lasers. This study aimed to assess knowledge of the population to plan awareness programs and establish protective health policies. METHODS: This observational cross-sectional study used a newly-developed, validated, and pilot-tested questionnaire to survey attendees of football matches in Saudi Arabia between September to October 2018. RESULTS: Five-hundred and sixty-nine attendees were surveyed, and 76% of respondents knew laser pointers were harmful and could damage the eye. However, 73% of respondents did not think that the blue laser was dangerous, indicating poor awareness regarding this particular laser. Only 38% knew which ocular structure is most commonly damaged, and 15.6% did not realize that brief exposure can cause vision loss. Females had better knowledge compared to males. Respondents between 25 and 40 years old, females, and married individuals had the highest levels of a positive attitude. There was no statistically significant difference in the mean knowledge score between those in the medical field and other fields (P = 0.5). CONCLUSION: There is an inadequate knowledge of protective measures against handheld lasers. However, there's an overall positive attitude towards spreading awareness about this issue. Yet, targeted awareness campaigns are still needed in addition to more strict government laws to prevent importing or using high-powered handheld laser pointers.

Amsterdam tool for clinical medication review: development and testing of a comprehensive tool for pharmacists and general practitioners.

BACKGROUND: Drug-related problems are prevalent among older patients, and substantially increase the risk of morbidity, (re-)hospitalisation and mortality. To detect drug-related problems and optimize treatment primary caregivers should periodically review the medication of older patients. The aim was to develop a structured, comprehensive but practicable tool to facilitate and support the reviewing of medication of older patients with a chronic disease by pharmacists and general practitioners. METHODS: A tool facilitating clinical medication review by community pharmacists was developed on the basis of treatment guidelines, literature data on drug-related problems. For the identification of drug-related problems from the patient's perspective, a script for structured interviews was developed. The tool was optimized by means of a Delphi method with an expert panel and testing in a trial. RESULTS: The medication review tool consists of a comprehensive checklist of 124 drug-related problems divided by 20 sections according to physiological systems and diseases, and includes a structured interview script for a patient interviews. CONCLUSION: A structured, comprehensive and practical tool to assist pharmacists and general practitioners to perform clinical medication review including a list of potential drug-related problems in older patients with chronic disease, as well as a script for structured patient interviews, was developed.

Identification of drug-related problems of elderly patients discharged from hospital.

BACKGROUND: Drug-related problems (DRP) following hospital discharge are common among elderly patients using multiple drugs for the treatment of chronic diseases. The aim of this study was to investigate the occurrence of DRP in these patients using a specific tool for the identification of DRP by community pharmacists. METHODS: An observational study involving 340 patients aged over 60 years using at least five prescription drugs and discharged from hospital. The occurrence of DRP was assessed by means of an identification tool specifically developed for use by community pharmacists, including a semistructured patient interview and a checklist of common DRP. RESULTS: In total, 992 potential DRP were observed in the 340 patients (mean 2.9 ± 1.7). No drug prescribed but clear indication, an unnecessarily long duration of treatment, dose too low, and incorrect drug selection were the DRP most commonly observed. Ten percent of DRP occurring in 71 patients were drug-drug interactions. The number of DRP was related to the number of drugs prescribed. Frequently occurring DRP found using the patient interview were fear of side effects and no or insufficient knowledge of drug use. Medication of patients discharged from the pulmonary department and of those with type 2 diabetes was particularly associated with occurrence of DRP. CONCLUSION: Following hospital discharge, DRP occur frequently among elderly patients using five or more drugs for the treatment of chronic disease. The number of DRP increased with the number of drugs used. An important task for community pharmacists is to identify, resolve, and prevent the occurrence of DRP among this patient group. Since DRP are associated with an increased risk of hospital readmissions, morbidity, and mortality, it is very important to develop intervention strategies to resolve and prevent DRP.

Genetic variation for postzygotic reproductive isolation between Caenorhabditis briggsae and Caenorhabditis sp. 9.

The process of speciation is key to the origins of biodiversity, and yet the Caenorhabditis nematode model system has contributed little to this topic. Genetic studies of speciation in the genus are now feasible, owing to crosses between the recently discovered Caenorhabditis sp. 9 and the well-known C. briggsae producing fertile F(1) hybrid females. We dissected patterns of postzygotic reproductive isolation between these species by crossing eight isogenic strains of C. briggsae reciprocally with six strains of C. sp. 9. We determined that overall patterns of reproductive isolation are robust across these genetic backgrounds. However, we also quantified significant heritable variation within each species for interspecific hybrid incompatibilities for total adult progeny, egg-to-adult viability, and the percentage of male progeny. This demonstrates that intraspecific variation for interspecific hybrid incompatibility occurs despite extensive, albeit incomplete, reproductive isolation. Therefore, this emerging general phenomenon of variable reproductive isolation is not restricted to highly interfertile, early-stage incipient species, but also applies to species in the latest stages of the speciation process. Furthermore, we confirm Haldane's rule and demonstrate strongly asymmetric parent-of-origin effects (Darwin's corollary) that consistently manifest more extremely when hermaphroditic C. briggsae serves as maternal parent. These findings highlight Caenorhabditis as an emerging system for understanding the genetics of general patterns of reproductive isolation.

Effect of medication review and cognitive behaviour treatment by community pharmacists of patients discharged from the hospital on drug related problems and compliance: design of a randomized controlled trial.

BACKGROUND: Drug related problems (DRPs) are common among elderly patients who are discharged from the hospital and are using several drugs for their chronic diseases. Examples of drug related problems are contra-indications, interactions, adverse drug reactions and inefficacy of treatment. Causes of these problems include prescription errors and non-compliance with treatment. The aim of this study is to examine the effect of medication review and cognitive behaviour therapy of discharged patients by community pharmacists to minimize the occurrence of drug related problems. METHODS/DESIGN: A randomized controlled trial will be performed. Community pharmacists will be randomized into a control group and an intervention group. 342 Patients, aged over 60 years, discharged from general and academic hospitals, using five or more prescription drugs for their chronic disease will be asked by their pharmacy to participate in the study. Patients randomized to the control group will receive usual care according to the Dutch Pharmacy Standard. The medication of patients randomised to the intervention group will be reviewed by the community pharmacist with use of the national guidelines for the treatment of diseases, when patients are discharged from the hospital. The Pharmaceutical Care network Europe Registration form will be used to record drug related problems. Trained pharmacy technicians will counsel patients at home at baseline and at 1,3,6,9 and 12 months, using Cognitive Behaviour Treatment according to the Theory of Planned Behaviour. The patient's attitude towards medication and patient's adherence will be subject of the cognitive behaviour treatment. The counselling methods that will be used are motivational interviewing and problem solving treatment. Patients adherence towards drug use will be determined with use of the Medication Adherence Report Scale Questionnaire. There will be a follow-up of 12 months.The two primary outcome measures are the difference in occurrence of DRPs between intervention and control group and adherence with drug use. Secondary endpoints are attitude towards drug use, incidence of Re-hospitalisations related to medicines, functional status of the patient, quality of life and the cost-effectiveness of this intervention. DISCUSSION: Combining both medication review and Cognitive Behaviour Treatment may decrease DRPs and may result in more compliance with drug use among patients discharged from the hospital and using 5 or more chronic drugs. TRIAL REGISTRATION: Dutch Trial Register NTR1194.

Evidence-based practice among primary care physicians in Kuwait.

OBJECTIVES: The level of evidence-based practice (EBP) and awareness has not been previously assessed among primary care physicians in Kuwait. The objectives of this study were to quantify the level of EBP and awareness in Kuwait and identify the factors related to EBP. METHOD: We used a cross sectional study that enrolled 332 primary care physicians in 57 primary care centres randomly chosen in Kuwait. A self-administered questionnaire was used to collect the data with a response rate of about 93%. RESULTS: Although half of the physicians self reported that they use EBP most of the time, further analysis revealed that only about 24% of this group had a reasonable understanding of EBP. Most of the clinical practice in the Kuwaiti primary care system seems to be based on the clinician's own judgment or what they learned in the medical school and traditional text books, rather than evidence-based sources. None of the physicians had an Internet connection at their work place and a vast majority of them had no access to international journals nor were confident about critical appraisal of published evidence. CONCLUSION: Overall level of awareness of evidence-based medicine (EBM) among primary care physicians in Kuwait was considerably low. Training in the areas of EBM as well as making sure the Kuwaiti primary care centres have access to evidence-based sources are critically important if primary care in Kuwait were to become evidence based.
