Assessment of Healthcare System Capabilities and Preparedness in Yemen to Confront the Novel Coronavirus 2019 (COVID-19) Outbreak: A Perspective of Healthcare Workers

Background: In the past decade, Yemen has witnessed several disasters that resulted in a crumbled healthcare system. With the declaration of COVID-19 a global pandemic, and later the appearance of first confirmed cases in Yemen, there is an urgent need to assess the preparedness of healthcare facilities (HCFs) and their capacities to tackle a looming COVID-19 outbreak. Herein, we present an assessment of the current state of preparedness and capabilities of HCFs in Yemen to prevent and manage the COVID-19 outbreak. Methods: An online survey for HCFs was developed, validated, and distributed. The questionnaire is divided into five main sections: (1) Demographic variables for participants. (2) HCFs capabilities for COVID-19 outbreak. (3) Support received to face the emergence and spread of COVID-19. (4). Current practices of infection prevention and control measures in the HCFs. The last section focused on the recommendations to ensure effective and timely response to this outbreak in Yemen. Descriptive analysis was used to analyze data using statistical package for social sciences (SPSS), version 23. Results: Responses were received from healthcare workers (HCWs) from 18 out of 22 governorates in Yemen. Out of the 296 HCWs who participated in the study, the vast majority (93.9%) believed that the healthcare system in Yemen does not have the resources and capabilities to face and manage a COVID-19 outbreak. Approximately 82.4% of participants rated the general preparedness level of their HCFs as very poor or poor. More specifically, the majority of HCWs rated their HCFs as very poor or poor in term of availability of the following: an adequate number of mechanical ventilators (88.8%), diagnostic devices (88.2%), ICU rooms and beds (81.4%), and isolation rooms (79.7%). Conclusions: The healthcare facilities in Yemen are unprepared and lack the most basic resources and capabilities to cope with or tackle a COVID-19 outbreak. With the current state of a fragile healthcare system, a widespread outbreak of COVID-19 in Yemen could result in devastating consequences. There is an urgent need to provide support to the healthcare workers and HCFs that are on the frontline against COVID-19.
Malassezia spp. Yeasts of Emerging Concern in Fungemia

Malassezia spp. are lipid-dependent yeasts, inhabiting the skin and mucosa of humans and animals. They are involved in a variety of skin disorders in humans and animals and may cause bloodstream infections in severely immunocompromised patients. Despite a tremendous increase in scientific knowledge of these yeasts during the last two decades, the epidemiology of Malassezia spp. related to fungemia remains largely underestimated most likely due to the difficulty in the isolation of these yeasts species due to their lipid-dependence. This review summarizes and discusses the most recent literature on Malassezia spp. infection and fungemia, its occurrence, pathogenicity mechanisms, diagnostic methods, in vitro susceptibility testing and therapeutic approaches.
Neuropsychiatric Manifestation Screening Among Systemic Lupus Erythematosus Patients in Hasan Sadikin General Hospital Bandung

Background: Systemic Lupus Erythematosus (SLE) is an autoimmune diseases caused by deposition of immune complex with the involvement of various organ system and certain autoantibodies production. One of the most significant manifestation is neuropsychiatricsymptoms, known as NPSLE (Neuropsychiatric Systemic Lupus Erythematosus). This study aims to portray the distribution of neuropsychiatric manifestation of SLE patients using a screening method in Hasan Sadikin General Hospital.Method: An observative, descriptive categoric study, with consecutive sampling were done. Data were collected by spreading the questionnaire to subjects diagnosed as SLE who visiting Hasan Sadikin General Hospital during August-October 2016 and by tracingtheir medical records. Data analyzed included age, sex, education background, duration of lupus, diagnosis criteria, ongoing therapy, and neuropsychiatric manifestation.Result: Samples volunteered in this study were 97 patients. Of them 94 patients (96.9%) were women and 47 patients (48.5%) were senior high school graduated. Most common diagnosis criteria found was positive ANA test (91.8%). Most necessary ongoing therapygiven was methylprednisolone (96.9%). Common neuropsychiatric manifestations were mood disorders (73,2%), headache (57,7%), and mononeuropathy (51,5%). Conclusion: The common psychiatric, central nervous, and peripheral nervous manifestations were mood disorder, headache, and mononeuropathy, respectively.
AutoSEIR: Accurate Forecasting from Real-time Epidemic Data Using Machine Learning

Since the SARS-CoV-2 virus outbreak has been recognized as a pandemic on March 11, 2020, several models have been proposed to forecast its evolution following the governments' interventions. In particular, the need for fine-grained predictions, based on real-time and fluctuating data, has highlighted the limitations of traditional SEIR models and parameter fitting, encouraging the study of new models for greater accuracy. In this paper we propose a novel approach to epidemiological parameter fitting and epidemic forecasting, based on an extended version of the SEIR compartmental model and on an auto-differentiation technique for partially observable ODEs (Ordinary Differential Equations). The results on publicly available data show that the proposed model is able to fit the daily cases curve with greater accuracy, obtaining also a lower forecast error. Furthermore, the forecast accuracy allows to predict the peak with an error margin of less than one week, up to 50 days before the peak happens.
Assessing the Efficiency of Pan Traps for Collecting Bees (Hymenoptera: Apoidea)

Abstract Native bees provide important economic and ecological functions that include pollination of agricultural crops and natural plant communities, thus conservation of their declining populations is important. The use of pan traps for collecting and monitoring bee populations has become widespread because the method samples widely different habitats with equal effort. However, to the best of our knowledge no efforts have attempted to quantify their efficiency. We measured the efficiency of pan traps at collecting bees by using video cameras to record individuals coming to the traps. Videoed bees were classified as approaching the trap, making contact with the trap, or being captured. During 52 h of video, 16 bees (19%) were captured, 25 bees (30%) made contact with the trap but were not captured, and 42 bees (51%) approached the trap and departed without making contact. The results of this study suggest that pan traps collect <20% of the bees that are attracted to it and are likely to overestimate the abundance of smaller-bodied bees such as Lasioglossum spp.
A Case Series of Devastating Intracranial Hemorrhage During Venovenous Extracorporeal Membrane Oxygenation for COVID-19

Objective Anticoagulation may be a challenge in coronavirus disease 2019 (COVID-19) extracorporeal membrane oxygenation due to endothelial injury and dysregulation of coagulation, which may increase the risk of thrombotic and bleeding complications. This report was created to describe the authors’ single institutional experience, with emphasis on the high rate of intracranial hemorrhage for the first 10 patients with COVID-19 placed on venovenous extracorporeal membrane oxygenation (VV ECMO). Design Case series, retrospective analysis. Setting Single institution. Participants Ten patients. Interventions None. Measurements and Main Results Patient characteristics, mortality, stroke rate, and length of stay data were collected in all patients. In addition, laboratory values of D-dimer and C-reactive protein and standard measurements of prothrombin and activated partial thromboplastin time were collected on all patients. Ten patients, each confirmed with COVID-19 via reverse transcription-polymerase chain reaction, were supported on VV ECMO for acute respiratory distress syndrome (ARDS) for a mean duration of 9.4 ± 7 days. Four of 10 patients had hemorrhagic strokes, 3 of which resulted in death. At 30 days after initiation of VV ECMO, a total of 7 survivors included 6 patients discharged from the hospital and 1 patient who remained in the intensive care unit. Conclusions In this small study of 10 patients, intracranial hemorrhage was a common complication, resulting in a high rate of death. The authors urge caution in the anticoagulation management of VV ECMO for patients with severe ARDS and COVID-19 patients. Close monitoring of all hematologic parameters is recommended during ECMO support while awaiting larger, multicenter studies to examine the best practice.
Public Reactions towards the COVID-19 Pandemic on Twitter in the United Kingdom and the United States

Background: The coronavirus disease 2019 (COVID-19) has spread globally since December 2019. Twitter is a popular social media platform with active discussions about the COVID-19 pandemic. The public reactions on Twitter about the COVID-19 pandemic in different countries have not been studied. This study aims to compare the public reactions towards the COVID-19 pandemic between the United Kingdom and the United States from March 6, 2020 to April 2, 2020. Data: The numbers of confirmed COVID-19 cases in the United Kingdom and the United States were obtained from the 1Point3Acres website. Twitter data were collected using COVID-19 related keywords from March 6, 2020 to April 2, 2020. Methods: Temporal analyses were performed on COVID-19 related Twitter posts (tweets) during the study period to show daily trends and hourly trends. The sentiment scores of the tweets on COVID-19 were analyzed and associated with the policy announcements and the number of confirmed COVID-19 cases. Topic modeling was conducted to identify related topics discussed with COVID-19 in the United Kingdom and the United States. Results: The number of daily new confirmed COVID-19 cases in the United Kingdom was significantly lower than that in the United States during our study period. There were 3,556,442 COVID-19 tweets in the United Kingdom and 16,280,065 tweets in the United States during the study period. The number of COVID-19 tweets per 10,000 Twitter users in the United Kingdom was lower than that in the United States. The sentiment scores of COVID-19 tweets in the United Kingdom were less negative than those in the United States. The topics discussed in COVID-19 tweets in the United Kingdom were mostly about the gratitude to government and health workers, while the topics in the United States were mostly about the global COVID-19 pandemic situation. Conclusion: Our study showed correlations between the public reactions towards the COVID-19 pandemic on Twitter and the confirmed COVID-19 cases as well as the policies related to the COVID-19 pandemic in the United Kingdom and the United States.
Total elbow replacement – patient selection and perspectives

Total joint replacements for elbow arthritis were developed in the late 1960s at the same time as total joint replacements for knee joint arthritis. Since then, there has been a continuing annual increase in the number of patients treated with total knee joint replacement for arthritis, in line with replacement arthroplasty of the other major limb joints, but in contrast to total elbow joint replacement which is falling, since reaching a peak in the 1990s. Which raises the question, why? Continuing controversy about implant design, the relatively high reported complication rates associated with total elbow replacement (TER) and the difficulties encountered in revision surgery are identified as reasons together with changes in the patient population currently treated with TER. The purpose of this review is to explore the reasons for this in the context of the patient population requiring implant surgery for elbow arthritis and our current perspective of elbow pathology requiring treatment. This is not a systematic review of the whole of the literature concerning total elbow joint replacement arthroplasty but is drawn largely from the supporting literature that reflects my own clinical experience and illustrated with teaching materials I have commissioned together with radiographs and intraoperative photographs of patients I have treated.
Stigmasterol treatment increases salt stress tolerance of faba bean plants by enhancing antioxidant systems

The effect of different concentrations of NaCl (100, 150, and 200 mM) on cell membrane stability, photosynthetic pigment and carbohydrate contents, antioxidant enzymes activities, glutathione contents, and lipid peroxidation (malondialdehyde content) in faba bean ( Vicia faba ) leaves were investigated. In addition, the role of stigmasterol, a promising plant development regulatory substance in increasing tolerance to salt stress was evaluated. The results revealed that salt-stressed bean plants treated with stigmasterol had an increased membrane stability index, and photosynthetic pigment and carbohydrate contents compared with salt-stressed plants untreated with stigmasterol. The level of antioxidant system components (catalase, ascorbic acid peroxidase, and reduced glutathione) increased in response to stigmasterol treatment. Enhanced antioxidant activities helped to decrease oxidative damage from salt and develop tolerance against salt stress in stigmasterol-treated faba bean plants. An increase in the degree of salt tolerance induced by stigmasterol was indicated by the improvement of the membrane stability index, photosynthetic activity and consequently the carbohydrate pool. The data provided evidence that stigmasterol treatment reduced the adverse effects of salt stress on faba bean plants, and might play a key role in providing stress tolerance by stimulation of the antioxidant system as a stress protection mechanism.
Stand biomass dynamics of pine plantations and natural forests on dry steppe in Kazakhstan

Biomass dynamics were studied in isolated relict stands of Scots pine (Pinus sylvestris L.) on the dry steppe of Kazakhstan (53–54° N), where potential evaporation is 500–600 mm yr−1 and the rainfall is 250–260 mm yr−1. Samples were taken from seven plots in natural stands on sandy forest soils (aged 13–110 yrs) and ten plots in plantations on dark‐chestnut‐coloured soils (aged 5–50 yrs). Nine or ten sample trees were taken from each plot, giving a total of 68 and 96 sample trees in natural and plantation stands respectively. Root systems were excavated and fractionated in 11 plots. Analyses indicated that the stability of these stands becomes critical at 10–20 yrs, when foliage biomass reaches its maximum (7–13 t ha−1 dry weight), both in plantations and natural stands. Self‐regulating mechanisms in natural stands provide stability that may not develop in some plantations. Natural stands may show an abrupt decrease in foliage biomass at the time of canopy closure, but it increases again by age 40–50 yrs.
Seedling growth of four fire-following Mediterranean plant species deprived of single mineral nutrients.

1.Anthyllis vulneraria, Cistus creticus, Hippocrepis unisiliquosa and Pinus brutia are frequent post-fire colonizers whose seedlings are subjected to the mineral conditions imposed by ash in the early stages of growth. We test the hypothesis that the effective internal supply of mineral elements in the seeds of these species may complement the external availability of specific nutrients. 2. Newly germinated seedlings were grown in nutrient solutions, each deficient in one of the following elements: nitrogen, phosphorus or potassium. Control treatments consisted of full nutrients and distilled water. Seedling growth was monitored over 12weeks. The final dry masses of the seedlings were taken as a measure of the availability of each element from the seeds’ own stored reserves. 3. For the two legume species nitrogen was the most limiting element followed by phosphorus. Potassium deficiency had no effect on the final legume dry biomass. For Cistus, the order was nitrogen followed by potassium, while phosphorus deprivation had no effect on growth during the 12weeks of the experiment. Deprivation of single minerals had no significant effect on seedling growth of Pinus over the same period. The two legumes and Cistus when denied nitrogen had relatively greater relative root ratios than control plants. 4. The relative seedling requirements of each species for early external supplies of the various nutrients for establishment in the field are discussed with reference to the adaptation of the four species to post-fire regeneration.
Effect of bedding type and transient wetness on footpad dermatitis in broiler chickens

SUMMARY a high incidence of footpad dermatitis (FPD) is undesirable in broiler chicken production in terms of both animal welfare and profitability. Bedding type and bedding quality have been identified as possible causative agents of FPD. Four randomized block trials were conducted to determine whether bedding type and transient elevation in moisture influenced the incidence and severity of FPD in broiler chickens. in addition to broiler growth performance and litter moisture, the incidence and severity of FPD was assessed at different ages. the incidence of FPD was significantly increased when the litter moisture was increased by wetting at 14 d of age, but not when the broilers were older than 56 d of age. the severity of FPD was reduced with the improvements in bedding quality. Moreover, particle size of the litter had a direct effect on the occurrence of FPD. Wetting treatment and litter type had little influence on the live performance of broilers in 4 successive trials. From the standpoint of FPD etiology, litter moisture level and particle size may be crucial factors in the development of FPD. Similarly, FPD may be occurring early in the grow-out period, and subsequent improvements in litter quality could reverse the severity of lesions in market-age broilers.
The Professional Activities of Nurse Managers in Chinese Hospitals: A Cross-Sectional Survey in Hunan Province.

OBJECTIVE To explore nurse managers' perceptions of the frequency and importance of professional activities performed in their daily work in public hospitals in Hunan, China. BACKGROUND Nurse managers are responsible for the management of almost all nursing activities in Chinese hospitals. Understanding how nurse managers operationalize their role and their perceptions of the importance of each activity is essential for clarification of their role and the competencies required to perform it. METHODS A cross-sectional questionnaire survey. RESULTS A total of 1371 nurse managers in Hunan province completed the survey. Nursing quality/safety management and patient management were performed most frequently and perceived as most important. Nurse managers performed nursing information management frequently while perceiving it as less important. They seldom performed nursing research management and placed low value on it. CONCLUSIONS Patient-centred care remains central to nursing management. Nursing managers can create a leadership culture in their hospital settings that includes the effective management of information and facilitation of research knowledge to benefit nurse managers, staff and patients. IMPLICATIONS FOR NURSING MANAGEMENT The results provide evidence for standardization of roles and job descriptions of nurse managers and for developing their knowledge and skills to ensure quality patient care.
Feasibility of routine ultrasound-guided percutaneous transluminal angioplasty in the treatment of native arteriovenous fistula dysfunction

Background: Stenosis is the main cause of arteriovenous fistula failure and is due to neointimal hyperplasia. Percutaneous transluminal angioplasty is the gold standard for patients with vascular access stenosis. The aim of the study was to evaluate the efficacy and safety of ultrasound-guided percutaneous transluminal angioplasty in the treatment of native arteriovenous fistula venous stenosis. Methods: The need for intervention was determined by physical examination and duplex ultrasound in 162 patients. All patients with failing or not maturing arteriovenous fistula were treated in the outpatient setting under ultrasound guidance. Procedural success was assessed with repeated post-procedural ultrasound examinations. All procedures were performed under local anesthesia by a single nephrologist and were performed in a single vascular laboratory, while follow-up ultrasound was performed in the dialysis unit of destination. Results: Early technical success was obtained in 95.6% of cases (154 of 162). Complications occurred in 22 patients (13.5%) with no major complication requiring surgical or fluoroscopic endovascular intervention. Primary patency at 6 and 12 months was 84% and 69.8%, respectively. Risk factors for arteriovenous fistula failure/secondary percutaneous transluminal angioplasty were vascular access low blood flow rate and vintage, as well as the need for thrombolysis during the first percutaneous transluminal angioplasty. Conclusion: Ultrasound-guided percutaneous transluminal angioplasty is a valuable tool to treat vascular access stenosis.
Post-Renal Transplant Metabolic Acidosis: A Neglected Entity

Metabolic acidosis is a prevalent yet overlooked entity among renal transplant recipients (RTRs) and incurs adverse effects on graft function. Although graft dysfunction and calcineurin inhibitor usage have been linked with renal tubular acidosis (RTA), there is no Indian data on prevalence or risk factors of post-transplant acidosis. A cross-sectional study was conducted on 106 adult RTRs, with a transplant duration of >6 months and an estimated glomerular filtration rate (GFR) >40 ml/min/1.73 m2. Acidosis was diagnosed on basis of plasma bicarbonate and arterial pH. Serum and urine electrolytes with anion gap were determined to diagnose and type RTA. Acidosis was diagnosed in 44 of 106 patients (41.5%) with 23 (52.27%) having severe acidosis. Type I RTA was the most common subtype (52.5%) followed by type IV (30.9%) and type II RTA (7.5%). The correlation between estimated glomerular filtration rate and acidosis was minimally linear (r = 0.1088), with multivariate analysis revealing previous acute rejection episodes, current serum tacrolimus levels, cotrimoxazole usage and intake of animal proteins to be independent risk factors. The serum albumin levels were low in the acidosis group and showed linear correlation with bicarbonate levels (r = 0.298). There is a high prevalence of metabolic acidosis in RTRs with type I RTA being most common subtype. Screening of RTRs on a regular basis is a feasible approach for early diagnosis and intervention. However, prospective studies are needed to demonstrate the effect of acidosis on graft survival and benefit of bicarbonate therapy in RTRs.
