Cholelithiasis is the most common biliary tract disorder. Surgery is the treatment of choice for symptomatic gallstones. Aims of this study were to investigate the feasibility and short-term safety of a new endoscopic procedure with a specially designed Nitinol gallbladder stent for blockage of gallstone migration, the Shai™ Stent. The Shai stent is designed to enable free bile flow, which will be supposed to prevent recurrent attacks. The Shai™ Stent was inserted into the gallbladder during a standard ERCP procedure using a conventional metal stent delivery system. The aim of the present study was to investigate the feasibility and safety of insertion and deployment and removal of the stent into the gallbladder of pigs. In addition, the short-term safety of the stent was evaluated. Fifteen stents were placed in the gallbladder of 15 pigs. Mean procedure time was 25 min (15–37). The maximum follow-up before sacrifice was 42 days. The stent in 1 pig had migrated at the 42 days follow-up but there were no macroscopic changes in its gallbladder or other organs. The stent remained in place in the remaining 12 pigs at autopsy, and the gallbladder and bile ducts were macroscopically normal. Stent removal was easily done in two pigs immediately after placement. Correct placement and removal of the Shai™ Stent in the gallbladder is safe and feasible in pigs. Further clinical trials are warranted to confirm these results and to effectively evaluate the capability of this stent as an innovative biotechnology to block gallstones from migration and impaction.

Acute kidney injury (AKI) is a highly fatal complication of malaria. We used the Kidney Disease Improving Global Outcomes (KDIGO) and Pediatric Risk, Injury, Failure, Loss, End-Stage Kidney Disease (pRIFLE) guidelines to assess AKI among children. One hundred children with Plasmodium falciparum malaria were recruited from the St. Andrew's Catholic Hospital. Admission and 48-h serum creatinine were estimated. Weight and height of the participants were measured, and AKI status determined with the KDIGO and pRIFLE guidelines. A questionnaire was used to collect the socio-demographic and clinical data of participants. Two percent and 5% of the participants had AKI according to the KDIGO and pRIFLE criteria, respectively. Per the KDIGO guidelines, 1% of the participants had Stage 2 and 1% also had Stage 3 AKI. Four percent had Stage 1 (risk) and 1% had Stage 2 (injury) AKI per the pRIFLE criteria. Participants with AKI were dehydrated, and neither had sepsis or on antibiotics when the KDIGO guideline was used. Participants who had AKI were dehydrated, with 80% having sepsis and 40% on antibiotics when the pRIFLE criteria were used. There was no association between the KDIGO and pRIFLE criteria with respect to AKI status of participants (k = -0.029, P = 0.743). Two percent and 5% of the study participants had AKI when the KDIGO and pRIFLE guidelines were used respectively. One percent of the participants had Stage 2 and 1% also had Stage 3 AKI per KDIGO; 4% had Stage 1 (risk) and 1% had Stage 2 (injury) AKI per the pRIFLE.

The article sought to discuss the impact of value chain development and local economic development among rice farmers in Asutuare in the Shai-Osudoku District Assembly of Ghana. The study specifically examined the actors in the rice value chain development process, their roles and how their roles shaped the final output for the consumer and the extent to which the value chain development and local economic development resulted in job opportunity creation, income generation, and poverty reduction in the area. Using the mixed method, the study found that the actors in the value chain process could be grouped into four. They are pre- production actors, which is made of actors involved in activities such as land preparation, tilling, bonding and spraying; production actors who are mainly made up of the actual rice farmers; post production actors who include those involved in harvesting, threshing milling among others; and financing system actors, which involves financial institutions and individual financiers (sponsors). The study opines that rice value chain and local economic development resulted in both direct and indirect employment and income generation for the rice farmers and the “agrigators”. However, there was a mixed outcome in poverty reduction in that 5.3% of the actors sampled for the study were below the poverty line, while the remaining 94.7% were above the poverty line. Challenges such as lack of access to finance, absence of sufficient rice processing factories, poor road networks, and lack of modern agriculture equipment were hindrances to effective rice value chain and local economic development promotion. Based on the findings and challenges, the following were recommended: the establishment of a rice processing factory in the Asutuare area as part of the One District One Factory policy, consistent fiscal policy aimed at supporting rice farmers in the locality, and the provision of modern equipment to modernize rice production. Key words: Local economic development, value chain, value chain development, poverty reduction.

With the popularity of phrases such as “shai( Open image in new window ) + Open image in new window (happiness)” and “xiu( Open image in new window ) + Open image in new window (loves)”, more and more nouns or noun phrases are coming into the structures of “shai( Open image in new window ) + NP” and “xiu( Open image in new window ) + NP”. In such a structure, the intuitive and cognitive perception is that “ shai( Open image in new window ) + NP” and “ xiu( Open image in new window ) + NP” express similar semantic connotations. But in the process of observing the corpus, we find that some nouns or noun phrases are unable to replace each other. With regard to this language phenomenon, we take the BCC Corpus of Beijing Language and Culture University as the research corpus, from which the relevant corpus is extracted, and discuss the similarities and differences between the two language structures from two aspects of word formation ability and collocation words by observing the collocation of index lines.

Background. Dysmenorrhea has been the most common gynecological problem worldwide. Reports of dysmenorrhea are greatest among individuals in their late teens and 20s and usually declining with age. It has also been reported that dysmenorrhea affects more than 80% of women in the reproductive age. The study objective was to examine the predictors of dysmenorrhea, its effect, and coping mechanisms among adolescents in Shai Osudoku District, Ghana. Methods. We conducted a cross-sectional study in September and November 2017 in selected schools in Shai Osudoku District, Ghana. We employed self-administered questionnaire to obtain data from adolescents volunteered to participate in the study. We analyzed the data using the SPSS programme IBM version 20. We used the Pearson chi-square test and multiple logistic regression analysis to assess the association between exposure variables and the outcome variable. The odds ratio was reported to establish the risk of dysmenorrhea at a confidence interval of 95%, and statistical significance was assumed at p<0.05. Results. The prevalence of dysmenorrhea was 68.1% (95% CI, 65.0–72.0) with one-third recounting their pain as severe. The pain during menstruation negatively influences the daily physical activities (22.5%), school attendance (6.9%), concentration during classes’ hours (27.9%), and academic performance (31.1%) of the respondents. Besides, adolescents who do not live with their parent experienced a 53.1% increase in odds of self-reporting dysmenorrhea (AOR, 1.53 (95% CI, 1.02–2.23)). Similarly, respondents who had irregular menstrual cycle experienced a 72.5% increase in odds of self-reporting dysmenorrhea (AOR, 1.73 (95% CI, 1.16–2.57)). Finally, a significant association between irregular menstrual cycle (p<0.01), not lived with their parent (p<0.04), and self-reported dysmenorrhea was found. Conclusion. This study establishes that dysmenorrhea is high among adolescents in Shai Osudoku District which negatively affects the daily activity of majority of them.

Purpose – This paper aims to investigate the information-seeking behaviour of traditional leaders in the Shai Osudoku District of Ghana. Design/methodology/approach – The case study methodology was used. An interview schedule was designed to elicit information from 12 chiefs from the Shai Traditional Council. Findings – The findings of the study showed that traditional leaders sought information on issues that bordered on their community as well as information for their personal use. It also showed that they usually used informal sources such as the traditional council and their subjects but also exhibited similar information-seeking behaviour to that of professionals. They also used information dissemination or transfer methods that were in line with the oral culture of their traditional society. They had challenges in the use of information technology due to their low educational level, as well as challenges in having access to formal sources due to unavailability. Practical implications – The study brought to light the challenges traditional leaders encountered in executing their roles. It was therefore recommended that government agencies collaborate with them to enhance their work. Originality/value – Several studies have been conducted on information-seeking behaviour of different categories of people within different contexts. However, few studies have been conducted on the information-seeking behaviour of traditional leaders. This study thus sought to serve as a foundation research on the information-seeking behaviour of traditional leaders, with Shai Osudoku District of Ghana as the study area.

The focus of the study was to investigate health information seeking behavior as well as the barriers to health information seeking among rural dwellers in Ghana using Shai Osudoku District as a case study. The convenient and purposive sampling technique was used to sample 210 community members within Shai Osudoku District. The Statistical Package for Social Sciences (SPSS) version 21.0 was employed to process the quantitative data. The data was processed into statistical tables and charts for interpretation and discussion. The outcome of the study revealed that the most common sources of health information seeking among rural community members in the district of investigation are posters, health care providers and families/friends, with radio being the most used platform. It was also revealed that those respondents with higher level of education are more likely to use the Internet and television in accessing health information (p = 0.001 and 0.000 respectively). Similarly, respondents with primary education or informal education were more likely to contact family members for health information (p = 0.001) The outcome of the study also shows that many rural communities in Ghana, particularly rural dwellers of Shai Osudoku District, face numerous challenges in accessing health information. Notable among them are language barrier, location of the villages and inaccessibility to emerging technologies such as mobile phones and television sets. We conclude that, policies for improving health information access and reducing barriers to health information seeking in rural communities should be designed and implemented by Ghana health service. Also, education on how to access health-related information with easily accessible sources either free or at low-priced could be a way to help people in rural settings in Ghana with limited health information.

The objective of this study was to assess livelihood opportunities among smallholder farmers in five communities namely Dodowa, Ayikuma, Agomeda, Asutsuare and Doryum in the Shai Osudoku district of the Greater Accra Region, Ghana. One hundred and fifty (150) farmers were selected from the Shai Osudoku district using multi-stage sampling procedure. Purposive sampling was used to select these communities due to their intensive involvement in farming. Furthermore, simple random sampling technique was adopted to pick 150 farmers for the survey. The study showed that farm households were able to 'pair' their farming activities with alternative livelihoods without abandoning their primary livelihoods, which is farming. The income levels of farmers from their primary livelihood activities were comparatively low with majority, 82.7%, earning GH₵ 100 or less every month compared with fewer farmers, 13.3%, earning above GH₵ 150. However, more than half of farmers (58%) earned above GH₵ 150 every month from their alternative livelihoods. Again, farmers who decided to undertake their primary and alternative livelihoods concurrently have seen a rise in the level of their income and accordingly contributing to the reduction of income poverty among rural farm households.

Background Influenza vaccination is recommended by the World Health Organization for high risk groups, yet few data exist on influenza disease burden in West Africa. Methods We estimated medically attended influenza-associated illness rates among residents of Shai-Osudoku and Ningo Pram-Pram Districts (SONPD), Ghana. From May 2013 to April 2015, we conducted prospective surveillance for severe acute respiratory illness (SARI) and influenza-like illness (ILI) in 17 health facilities. In 2015, we conducted a retrospective assessment at an additional 18 health facilities to capture all SONPD SARI and ILI patients during the study period. We applied positivity rates to those not tested to estimate total influenza cases. Results Of 612 SARI patients tested, 58 (9%) were positive for influenza. The estimated incidence of influenza-associated SARI was 30 per 100,000 persons (95% CI: 13-84). Children aged 0 to 4 years had the highest influenza-associated SARI incidence (135 per 100,000 persons, 95% CI: 120-152) and adults aged 25 to 44 years had the lowest (3 per 100,000 persons, 95% CI: 1-7) (p

According to creation theory, opportunities do not exist independently of entrepreneurs; instead they are created by the actions of entrepreneurs. However, little is known about the process of how opportunities are actually acted upon. We explore the role of communication in opportunity enactment by analysing an extreme case: Shai Agassi and the frequently cited business model innovation of his company Better Place, with which he wants to eliminate the car industry’s dependence on oil. For the first time, we take a look at the practice of communication of the case and find patterns that play a vital role in creating a market. The findings of our case study research can help entrepreneurs to understand communication practices for changing an established industry. The findings also further advance our understanding of entrepreneurial practices within creation theory.

Working with Teenage Parents: Handbook of Theory and Practice for Practitioners Working with Pregnant Teenagers, Young Parents and Their Children By J. Raphael-Leff, N. Malberg, D. Shai, M. Mills, E. Hopper, M. Zaphirious Woods, Anna Freud Centre, 2011, £15.00, pb, 258 pp. ISBN: 9780954931933

Successful worm detection at real-time OC-48 and OC-192 speed requires hardware to extract web based binary sequences at faster than these speeds, and software to process the incoming sequences to identify worms. Computer hardware advancement in the form of field programmable gate arrays (FPGAs) makes real-time extraction of these sequences possible. Lacking are mathematical algorithms for worm detection in the real time data sequence, and the ability to convert these algorithms into lookup tables (LUTs) that can be compiled into FPGAs. Data Modeling provides the theory and algorithms for an effective mathematical framework for real-time worm detection and conversion of algorithms into LUTs. Detection methods currently available such as pattern recognition algorithms are limited both by the amount of time to compare the current data sequence with a historical database of potential candidates, and by the inability to accurately classify information that was unseen in the training process. Data Modeling eliminates these limitations by training only on examples of nominal behavior. This results in a highly tuned and fast running equation model that is compiled in a FPGA as a LUT and used at real-time OC-48 and OC-192 speeds to detect worms and other anomalies. This paper provides an overview of our approach for generating these Data Change Models for detecting worms, and their subsequent conversion into LUTs. A proof of concept is given using binary data from a WEBDAV, SLAMMER packet, and RED PROBE attack, with BASIC source code for the detector and LUT provided.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.

The aim of this study is to assess the benefit of transcutaneous electrical nerve stimulation (TENS) for persons diagnosed with fibromyalgia.Patients and Methods: Adults meeting diagnostic criteria for fibromyalgia were randomized in a double-blind trial to receive either an active (n=62) or sham (n=57) wearable TENS device for 3-months. Subjects were classified as having lower or higher pain sensitivity by Quantitative Sensory Testing (QST). Patient Global Impression of Change (PGIC, primary outcome) and secondary efficacy measures including Fibromyalgia Impact Questionnaire (FIQR), Brief Pain Inventory (BPI) and painDETECT questionnaire (PDQ) were assessed at baseline, 6-weeks and 3-months. Treatment effects were determined by a mixed model for repeated measures (MMRM) analysis of the intention-to-treat (ITT) population (N=119). A pre-specified subgroup analysis of pain sensitivity was conducted using an interaction term in the model.Results: No differences were found between active and sham treatment on PGIC scores at 3-months (0.34, 95% CI [− 0.37, 1.04], p=0.351) in the ITT population. However, in subjects with higher pain sensitivity (n=60), PGIC was significantly greater for active treatment compared to sham (1.19, 95% CI [0.24, 2.13], p=0.014). FIQR total score (− 7.47, 95% CI [− 12.46, − 2.48], p=0.003), FIQR pain item (− 0.62, 95% CI [− 1.17, − 0.06], p=0.029), BPI Interference (− 0.70, 95% CI [− 1.30, − 0.11], p=0.021) and PDQ (− 1.69, 95% CI [− 3.20, − 0.18], p=0.028) exhibited significant improvements for active treatment compared to sham in the ITT population. Analgesics use was stable and comparable in both groups.Conclusion: This study demonstrated modest treatment effects of reduced disease impact, pain and functional impairment from wearable TENS in individuals with fibromyalgia. Subjects with higher pain sensitivity exhibited larger treatment effects than those with lower pain sensitivity. Wearable TENS may be a safe treatment option for people with fibromyalgia.Clinicaltrials.gov Registration: NCT03714425.Keywords: fibromyalgia, wearable, transcutaneous electrical nerve stimulation, neuromodulation, non-pharmacological treatment, clinical trial

Background: Auricular keloids belong to the most perplexing medical conditions, which have significant psychosocial impact on the patient’s body image and quality of life. Summary: The article is purposed to provide dermatologists and plastic surgeons with the best proven practice using intralesional cryosurgery for the treatment of the different auricular keloid types in order to obtain superior clinical results by minimizing the probability of recurrence. In the past 20 years, the authors have developed novel procedures in order to increase the effectiveness of intralesional cryosurgery on auricular keloids, including hydrodissection, warm gauze technique, and excision of dangling skin. Long-lasting clinical results with a low recurrence rate and a satisfactory aesthetic outcome are achieved with no deformation of the ear framework.

Background Adherence to direct oral anticoagulants (DOACs) remains a concern among non‐valvular atrial fibrillation (AF) patients. We aimed to assess patterns of adherence with DOACs and examine their association with ischemic stroke and systemic embolism (SE). Methods This retrospective cohort study includes all adult members of Clalit Health Services, the largest healthcare provider in Israel, with newly diagnosed non‐valvular AF between January 2014 and March 2019, who initiated DOACs within 90 days of AF diagnosis and used DOACs exclusively. Adherence was assessed using the proportion of days covered (PDC) over the first year of treatment, and high adherence was defined as PDC ≥80%. Regression models were used to identify predictors of high adherence to DOACs and to examine the association between adherence and stroke or SE. Results Overall 15,255 patients were included in this study. The proportion of highly adherent (PDC ≥80%) DOACs users was around 75% and decreased slightly over the years. On multivariable analyses, the likelihood of high adherence to DOACs increased with age and across higher socioeconomic classes, and was more likely among females, Jews, statins users, and patients with CHA2DS2‐VASc score ≥2. Risk of stroke and SE was lower among highly adherent DOACs users; adjusted HR 0.56 (95% CI, 0.45–0.71), compared to users with PDC

BACKGROUND & AIMS There is a lack of convenient, sensitive, non-invasive strategies for screening and surveillance for colorectal neoplasia. An assay combining the results of circulating gastrointestinal epithelial cells (CEC) and somatic mutations of cell-free DNA adjusting for age/sex using a unique algorithm is evaluated in patients requiring colonoscopy. METHODS A prospective single-site 458-subject study (asymptomatic: 43% screening/43% surveillance, enriched with 65 symptomatic subjects) undergoing colonoscopy was conducted. The test analyzed CEC and somatic mutations. The probability of advanced neoplasia (advanced adenoma (AA) and CRC) was determined by logistic regression methods adjusted for expected CRC incidence rate, prior history of AA, patient age and sex on a training subset. A linear predictor was developed to generate a score scaled from 0-100. The test performance was evaluated on an independent set of subjects using pre-specified algorithms and cutpoint. RESULTS Based on a pre-defined clinical threshold and predictive model derived from the training set (n=232), analysis of an independent asymptomatic validation set (n=194) yielded 89% (Lower exact one-sided 95% CI: 80%) specificity and 100% (95% CI: 37%)/78% (95% CI: 61%) sensitivity for detection of CRC/AA. In a secondary analysis, excluding surveillance subjects, the 97-subject screening cohort yielded 91% (95% CI: 79%) specificity and CRC/AA sensitivity at 100% (95% CI:37%)/83% (95% CI: 56%, 87% for advanced neoplasia 95% CI: 64%). Significant associations, (p CONCLUSIONS A multimodal blood test that included CEC and somatic mutations with adjustment for age and sex demonstrated high sensitivity for the diagnosis of advanced colorectal neoplasia. The resulting score captures prognostic information for CRC progression of index adenoma size and number and has the potential to enable stratification of patients for screening or post- polypectomy surveillance colonoscopy.

AML can be associated with autoimmune or inflammatory phenomena (AIP) occurring prior, concomitantly, or after its diagnosis. Trisomy 8 is one of the most common cytogenetic abnormalities associated with AML. We describe three patients with AML, trisomy 8, and associated AIP and review the known literature on this association. All of our patients had major symptomatic relief when treated with leukemia-directed therapy and corticosteroids. AIP in AML may be an underdiagnosed phenomenon, particularly in patients with trisomy 8.

Endoscopic findings in early esophageal cancer are often subtle and require careful inspection and meticulous endoscopic examination. When dysplasia is suspected, we recommend performing 1 or 2 targeted biopsies of the abnormal area and review with a pathologist specialized in evaluating gastrointestinal diseases. In the case of adenocarcinoma, after resection of any visible cancer, residual Barrett's can be treated by ablation. Endoscopic resection can offer the opportunity for patients to avoid surgery. Further studies are needed to evaluate the optimal management of circumferential and near-circumferential lesions as well as tools and techniques to facilitate the performance of endoscopic submucosal dissection and endoscopic mucosal resection.

We report a case of huge carcinosarcoma of lung initially presenting as an intra-abdominal mass: treatment with enucleation of the firm sarcomatous component followed by pulmonary resection. A 65-year-old man with mild mental retardation who smoked one pack of cigarettes per day until 1-month before he was admitted to our hospital complaining of a progressively poorer appetite, vomiting and an abdominal mass at the left upper quadrant region. Physical examination revealed a palpable mass over the left upper abdomen with percussion dullness of the lower hemithorax. Chest radiograph revealed a homogeneous mass lesion in the left lower lung field with obliteration of the costophrenic angle. Computed tomography scans of the chest disclosed a huge mass over the left lower thorax and upper abdomen with compression of the heart and shift of the esophagus and descending aorta to the midline. Sono-guided aspiration biopsy cytology revealed squamous cell carcinoma. Surgical intervention with enucleation of the very firm sarcomatous component with fragmentation followed by radical lobectomy. Chemotherapy was planned as adjuvant therapy in the postoperative period, but the patient's family declined it. The patient is currently survived without tumor recurrence 14 months after surgery. Our case revealed a huge tumor not only mediastinal compression but also initial presenting abdominal symptoms. Initially, from the symptoms and nonbiopsy study, we were unable to determine exactly if it was an intrathoracic tumor or an intra-abdominal tumor. This case highlights the importance of remaining clinically vigilant to differentiate an unusual tumor mass, and preoperative tissue proof is warranted.

Scarring of the face following chemical peeling is an uncommon and devastating complication. This case report describes the successful treatment of bulky mature keloids on both cheeks following deep chemical peeling by using a combined approach of intralesional cryosurgery followed by pulsed dye and ablative fractional CO2 laser therapy. Level of evidence: Level V, therapeutic study.

While perforations, postoperative fistulas, and leaks have traditionally led to surgical or interventional radiology consultation for management, the introduction of the over-the-scope clip has allowed increased therapeutic possibilities for endoscopists. While primarily limited to case reports and series, the over-the-scope clip successfully manages gastrointestinal bleeding, perforations, as well as postoperative leaks and fistulas. Retrospective studies have demonstrated a relatively high success rate and a low complication rate. Given the similarity to variceal banding equipment, the learning curve with the over-the-scope clip is rapid. However, given the higher risk of procedures involving the use of the over-the-scope clip, it is essential to obtain the scope in a stable position and grasp sufficient tissue with the cap using a grasping tool and/or suction. From our experience, while closure may be successful in lesions sized up to 3 cm, successful outcomes are obtained for lesions sized

Purpose Apparent diffusion coefficient (ADC) values in the developing fetus provide valuable information on the diagnosis and prognosis of prenatal brain pathologies. Normative ADC data has been previously established in 1.5 T MR scanners but lacking in 3.0 T scanners. Our objective was to measure ADC values in various brain areas in a cohort of normal singleton fetuses scanned in a 3.0 T MR scanner. Methods DWI (diffusion-weighted imaging) was performed in 47 singleton fetuses with normal or questionably abnormal results on sonography followed by normal structural MR imaging. ADC values were measured in cerebral lobes (frontal, parietal, temporal lobes), basal ganglia, and pons. Regression analysis was used to examine gestational age-related changes in regional ADC. Results Median gestational age was 30.1 weeks (range, 26-34 weeks). There was a significant effect of region on ADC values, whereby ADC values were highest in cerebral lobes (parietal > frontal > temporal lobes), compared with basal ganglia. The lowest values were found in the pons. On regression analysis, there was a decrease in ADC values in basal ganglia and pons with increasing gestational age. ADC values in frontal, parietal, and temporal lobes were stable in our cohort. Conclusion Regional brain ADC values in 3.0 T scanners are comparable with previously reported values in 1.5 T scanners, with similar changes over gestational age. Using 3.0 T scanners is increasing worldwide. For fetal imaging, establishing normal ADC values is critical as DWI enables a sensitive and quantitative technique to evaluate normal and abnormal brain development.

Introduction: Skin biopsies can be used to evaluate physiological effects of aging targeted intervention at the tissue/cellular levels. Recent clinical trials have shown that hyperbaric oxygen therapy (HBOT) can target aging hallmarks, including telomere shortening, senescent cells clearance and angiogenesis. The aim of this study was to evaluate the effects of HBOT on the skin of a normal, non-pathological, aging population. Methods: The study was performed as a prospective clinical trial. After signing informed consent and undergoing baseline evaluations, the subjects were assigned to a three-month control period followed by three months of HBOT daily sessions. Skin biopsies were taken at baseline, after three months of no intervention (control) and 1-2 weeks following the last HBOT session. Trichrome, Orecin, lipofuscin and CD31 staining were used to evaluate collagen fibers, elastic fibers, senescent cells and blood vessels, respectively. Results: Out of the cohort of 70 participants in the normal aging population study, thirteen male patients (age 68.07±2.5y) gave consent for repeated skin biopsies. Following HBOT, there was a significant increase in collagen density (p

Background COVID-19, the novel coronavirus, has caused a global pandemic affecting millions of people around the world. Risk factors for critical disease in adults are advanced age and underlying medical comorbidities, including cancer. Data are sparse on the effect of COVID-19 infection on pediatric patients with cancer during their active antineoplastic therapy. The optimal management of antineoplastic treatment during COVID-19 infection in this unique population is controversial. Aim To describe the severity and clinical course of COVID-19 infection in pediatric patients with cancer during active antineoplastic treatment and to study their course of treatment. Methods Clinical and laboratory data were collected from medical files of patients diagnosed with COVID-19, confirmed by polymerase chain reaction (PCR), who received active antineoplastic treatment between March 2020 and May 2021 in a large tertiary pediatric medical center. Results Eighteen patients with diverse pediatric cancers are described. They were infected with COVID-19 at different stages of their antineoplastic treatment regimen. Eight had an asymptomatic COVID-19 infection, nine had mild symptoms, and one had severe disease. All of them recovered from COVID-19 infection. Two patients experienced delays in their antineoplastic treatment; none of the other patients had delays or interruptions, including patients who were symptomatic for COVID-19. Conclusion In pediatric patients with cancer who test positive for COVID-19, yet are asymptomatic or have mild symptoms, the continuance of antineoplastic therapy may be considered.

Purpose To define injection index (II) and assess its impact on visual acuity (VA) in pigment epithelial detachment from age-related macular degeneration over 5 years. Methods Injection index is defined as the mean anti-vascular endothelial growth factor injections per year from presentation. A retrospective study of 256 eyes in 213 patients was performed. Patients were stratified by II (high: ≥9, low: Results Baseline characteristics showed no differences across II groups. Mean (range) follow-up, in years, was 5.02 (1.04-12.74) for all patients. Mean logMAR VA (Snellen VA) were 0.60 (20/80) and 0.56 (20/73) at baseline, 0.52 (20/66) and 0.59 (20/78) at Year 1, 0.45 (20/56) and 0.67 (20/94) at Year 2, 0.38 (20/48) and 0.66 (20/91) at Year 3, 0.41 (20/51) and 0.89 (20/155) at Year 4, and 0.35 (20/45) and 0.79 (20/123) at Year 5 for the high and low II groups, respectively. Linear regression analysis showed a gain of 0.5 approxETDRS letters with each additional injection per year. Conclusion Increased II was associated with better mean VA, suggesting that long-term continuous vascular endothelial growth factor suppression may improve VA in eyes thought to carry poor prognoses.

The growing human population is currently facing an unprecedented challenge on global food production and sustainability. Despite recognizing poultry as one of the most successful and rapidly growing food industries to address this challenge; poultry health and safety remain major issues that entail immediate attention. Bacterial diseases including colibacillosis, salmonellosis, and necrotic enteritis have become increasingly prevalent during poultry production. Likewise, outbreaks caused by consumption of undercooked poultry products contaminated with zoonotic bacterial pathogens such as Salmonella, Campylobacter and Listeria, are a serious public health concern. With antimicrobial resistance problem and restricted use of antibiotics in food producing animals, bacteriophages are increasingly recognized as an attractive natural antibacterial alternative. Bacteriophages have recently shown promising results to treat diseases in poultry, reduce contamination of carcasses, and enhance the safety of poultry products. Omics technologies have been successfully employed to accurately characterize bacteriophages and their genes/proteins important for interaction with bacterial hosts. In this review, the potential of using lytic bacteriophages to mitigate the risk of major poultry-associated bacterial pathogens are explored. This study also explores challenges associated with the adoption of this technology by industries. Furthermore, the impact of omics approaches on studying bacteriophages, their host interaction and applications is discussed.

Background: Acute kidney injury (AKI) affects up to 30% of patients undergoing cardiac surgery, leading to increased in-hospital and long-term morbidity and mortality. Teprasiran is a novel small interfering RNA that temporarily inhibits p53-mediated cell death that underlies AKI. Methods: This prospective, multicenter, double-blind, randomized, controlled phase 2 trial evaluated the efficacy and safety of a single 10 mg/kg dose of teprasiran versus placebo (1:1), in reducing the incidence, severity, and duration of AKI after cardiac surgery in high-risk patients. The primary end point was the proportion of patients who developed AKI determined by serum creatinine by postoperative day 5. Other end points included AKI severity and duration using various prespecified criteria. To inform future clinical development, a composite end point of major adverse kidney events at day 90, including death, renal replacement therapy, and ≥25% reduction of estimated glomerular filtration rate was assessed. Both serum creatinine and serum cystatin-C were used for estimated glomerular filtration rate assessments. Results: A total of 360 patients were randomly assigned in 41 centers; 341 dosed patients were 73±7.5 years of age (mean±SD), 72% were men, and median European System for Cardiac Operative Risk Evaluation score was 2.6%. Demographics and surgical parameters were similar between groups. AKI incidence was 37% for teprasiran- versus 50% for placebo-treated patients, a 12.8% absolute risk reduction, P =0.02; odds ratio, 0.58 (95% CI, 0.37–0.92). AKI severity and duration were also improved with teprasiran: 2.5% of teprasiran- versus 6.7% of placebo-treated patients had grade 3 AKI; 7% teprasiran- versus 13% placebo-treated patients had AKI lasting for 5 days. No significant difference was observed for the major adverse kidney events at day 90 composite in the overall population. No safety issues were identified with teprasiran treatment. Conclusions: The incidence, severity, and duration of early AKI in high-risk patients undergoing cardiac surgery were significantly reduced after teprasiran administration. A phase 3 study with a major adverse kidney event at day 90 primary outcome that has recently completed enrollment was designed on the basis of these findings (NCT03510897).

BACKGROUND: Temporal lobe T2 hyperintensity has been described in association with prenatal cytomegalovirus (CMV) infection on fetal MRI. However, these findings are often perplexing with high inter-observer variability. Our objective was to evaluate temporal lobe T2 signal quantitatively in prenatal CMV infection. METHODS: In this retrospective study, 119 fetuses, of which 51 fetuses with suspected CMV exposure (29–36 weeks of gestation) based on maternal seroconversion and age-matched 68 normal controls, were included. Mean and maximal temporal lobe T2 signal were evaluated quantitatively by measuring the T2 signal in the temporal lobes relative to the amniotic fluid’s signal. Intra-observer, inter-observer variability and diagnostic performance were assessed. The occurrence of neonatal sensorineural hearing loss (SNHL) was recorded. RESULTS: Relative temporal lobe T2 signal did not change along with the examined gestational age. Of our suspected CMV cohort, 29 fetuses were positive for fetal CMV infection on polymerase chain reaction (PCR) analysis. There were no statistically significant differences in the relative mean or maximal temporal lobes T2 signal between CMV positive, CMV negative fetuses, or normal controls. No correlation was found between neonatal SNHL and temporal lobe T2 signal. CONCLUSIONS: When temporal lobe T2 signal is analyzed quantitatively, CMV infected fetuses do not present an increased signal than age-matched controls. Thus, reported subjective temporal T2 hyperintensities should be interpreted carefully and should have a limited effect on pregnancy management, especially as an isolated finding. Our study illustrates the importance of quantitative imaging in diagnostic neuroradiology.

Background We recently reported that autologous fecal microbiota transplantation (aFMT), derived from the time of maximal weight-loss and administrated in the regain-phase, might preserve weight loss and glycemic control in moderately obese subjects, and is associated with specific microbiome signatures. Here, we sought to explore the global effect of aFMT on adipokines, inflammatory markers and blood cholesterol and on the overall gut microbiome preservation. Methods In the DIRECT-PLUS weight-loss trial, abdominally obese participants were randomized to three distinct weight-loss diets. Following the expected weight loss phase (0–6 m), 90 participants were randomized to receive their personal frozen fecal microbiota or placebo oral capsules (ten 1 g-capsules over ten sessions-total=100 g) during the expected weight regain phase (8–14 m). Results Of the 90 participants (age=52 yr; 0–6 m weight loss=-8.3 kg), 95.6% ingested at least 80/100 oral aFMT/placebo capsules over 6 months. Overall, the gut microbiome community structure was associated with plasma levels of leptin, cholesterol and interleukin-6 at baseline and after 6 m, whereas 6 m (weight loss phase) changes in specific microbiome species associated with the dynamic of leptin and inflammatory biomarkers. Following the 8–14 m aFMT administration phase, aFMT maintained decreased levels of leptin (ΔaFMT=-3.54 ng/mL vs. Δplacebo=-0.82 ng/mL;P = 0.04), C-reactive-protein (ΔaFMT=-1.45 mg/L vs. Δplacebo=-0.66 mg/L;P = 0.009), Interleukin-6 (ΔaFMT=-0.03pg/mL vs. Δplacebo=1.11pg/mL;P = 0.03) and total cholesterol (ΔaFMT=2.2 mg/dl vs. Δplacebo=13.1 mg/dl;P = 0.04) achieved in the weight loss phase. Overall, aFMT induced a significant preservatory effect on personal gut microbiome global composition (P = 0.03;Jensen-Shannon distance), as compared to placebo. Conclusions aFMT treatment in the regain phase might retain weight-loss induced metabolic benefits. These findings may suggest a novel aFMT treatment approach for personal metabolic attainment preservation.

Acute chorioamnionitis complicates 1-2% of all pregnancies and might increase the prevalence of endometritis that can cause Asherman syndrome or adhesions, but little is known about the direct effects of chorioamnionitis on future fertility. We aimed to evaluate the effect of chorioamnionitis on future fertility and obstetrics complications in patients diagnosed with chorioamnionitis during their pregnancy. We performed an observational, case-control retrospective study of pregnant women aged 18-40 years old, hospitalized with a diagnosis of chorioamnionitis between January 2013 and December 2017. The control group consisted of patients with similar demographic/obstetrics characteristics, matched with a ratio of 1:2 without chorioamnionitis. The prevalence of post gestational diagnostic hysteroscopy was significantly higher in the study group as compared to the control group (22.9% versus 9.0%, respectively

This article queries how learning analytics systems can support content-specific group formation to develop students’ thinking about a specific mathematical concept. Automated group formation requires identifying personal characteristics, designing tasks to probe students’ perceptions, and grouping them to increase individual learning chances. Designers of automated group formation recommendation modules (GFRMs) rarely consider content-specific objectives. We draw on theories on conceptual learning in mathematics and dialogic thinking to emphasize the role of a dialogic gap between students’ voices to enhance individual learning. In an experiment, fifty 8th and 9th grade students solved three mathematical tasks in a pre-intervention-post-set-up: individually, then in dyads, and then individually again. We used a learning analytics system to collect fine-grained content-specific data on students’ responses based on four pre-defined aspects of the parabola concept. We compared students’ answers with those of their peers in order to identify interpersonal relations. The experiment results indicate that students’ thinking about the parabola concept was the most successfully developed when every group member had a different perception of this concept. We illustrate the learning trajectories of four students and elaborate on the learning sequence of one of these students in particular. This article suggests that the centrality of a dialogic gap in developing personal learning is probably content independent. We thus call for software engineers to think about GFRMs that can support content-specific learning and instruction.

Third trimester amniocentesis is often performed when indications arise after 24 weeks of gestation—typically to investigate new sonographic findings, and might be related to pre-term birth. Scarcity of data exists concerning the risks of third-trimester amniocentesis in twin pregnancies. A retrospective cohort study of all twin gestations that underwent amniocentesis in a tertiary hospital between 2007 and 2016. Outcomes and procedure-related complications were compared between third-trimester (≥ 24 weeks) and mid-trimester amniocentesis (16–23 weeks). Primary outcome was defined as membrane rupture within four weeks of procedure. Logistic regression analysis was utilized to adjust results to potential confounders. Overall, 185 eligible women were included, of them, 28 (15.1%) underwent third-trimester amniocentesis and 157 (84.9%) underwent mid-trimester amniocentesis. Women in the third-trimester amniocentesis group were younger and presented higher frequencies of intra-uterine growth restriction (31.5 vs. 35.3, p

Tuberous sclerosis complex (TSC) is a genetic disorder characterized by multiorgan hamartomas, including cerebral lesions, with seizures as a common presentation. Most TSC patients will also experience neurocognitive comorbidities. Our objective was to use machine learning techniques incorporating clinical and imaging data to predict the occurrence of major neurocognitive disorders and seizures in TSC patients. A cohort of TSC patients were enrolled in this retrospective study. Clinical data included genetic, demographic, and seizure characteristics. Imaging parameters included the number, characteristics, and location of cortical tubers and the presence of subependymal nodules, SEGAs, and cerebellar tubers. A random forest machine learning scheme was used to predict seizures and neurodevelopmental delay or intellectual developmental disability. Prediction ability was assessed by the area-under-the-curve of receiver-operating-characteristics (AUC-ROC) of ten-fold cross-validation training set and an independent validation set. The study population included 77 patients, 55% male (17.1 ± 11.7 years old). The model achieved AUC-ROC of 0.72 ± 0.1 and 0.68 in the training and internal validation datasets, respectively, for predicting neurocognitive comorbidity. Performance was limited in predicting seizures (AUC-ROC of 0.54 ± 0.19 and 0.71 in the training and internal validation datasets, respectively). The integration of seizure characteristics into the model improved the prediction of neurocognitive comorbidity with AUC-ROC of 0.84 ± 0.07 and 0.75 in the training and internal validation datasets, respectively. This proof of concept study shows that it is possible to achieve a reasonable prediction of major neurocognitive morbidity in TSC patients using structural brain imaging and machine learning techniques. These tools can help clinicians identify subgroups of TSC patients with an increased risk of developing neurocognitive comorbidities.

Vascular dysfunction is entwined with aging and in the pathogenesis of Alzheimer's disease (AD) and contributes to reduced cerebral blood flow (CBF) and consequently, hypoxia. Hyperbaric oxygen therapy (HBOT) is in clinical use for a wide range of medical conditions. In the current study, we exposed 5XFAD mice, a well-studied AD model that presents impaired cognitive abilities, to HBOT and then investigated the therapeutical effects using two-photon live animal imaging, behavioral tasks, and biochemical and histological analysis. HBOT increased arteriolar luminal diameter and elevated CBF, thus contributing to reduced hypoxia. Furthermore, HBOT reduced amyloid burden by reducing the volume of pre-existing plaques and attenuating the formation of new ones. This was associated with changes in amyloid precursor protein processing, elevated degradation and clearance of Aß protein and improved behavior of 5XFAD mice. Hence, our findings are consistent with the effects of HBOT being mediated partially through a persistent structural change in blood vessels that reduces brain hypoxia. Motivated by these findings, we exposed elderly patients with significant memory loss at baseline to HBOT and observed an increase in CBF and improvement in cognitive performances. This study demonstrates HBOT efficacy in hypoxia-related neurological conditions, particularly in AD and aging.

Introduction: Fear of infection with SARS-CoV-2 has become widespread. All over the world, since the very beginning of the pandemic, older adults have been considered one of the groups at highest risk of SARS-CoV-2 infection and death due to COVID-19. The aim of the study was to evaluate the severity of anxiety symptoms related to COVID-19 in the older adults who are participants of the Universities of the Third Age in Poland. Material and methods: The study included participants of the University of the Third Age in Poland. A total of 296 persons were enrolled, including 258 women and 38 men. The study was a diagnostic survey, conducted with the use of the following validated psychometric scales: General Anxiety Disorder-7 (GAD-7), Short Health Anxiety Inventory (SHAI), and State-Trait Anxiety Inventory (STAI). Results: In two scales (STAI and SHAI), the mean scores demonstrated mild symptoms indicative of anxiety disorders in the older respondents. Women and men did differ significantly in terms of the scores obtained in STAI X-1 and STAI X-2. Single respondents differed significantly from divorced ones in terms of STAI X-1 scores. Moreover, widows/widowers differed significantly from divorced ones in terms of STAI X-2, and GAD-7 scores. Respondents declaring their financial status as average differed significantly from those declaring their financial status as good in terms of: STAI X-1, STAI X-2, SHAI, and GAD-7 scores. Conclusions: The subjective experience of anxiety symptoms associated with fear of contracting COVID-19 was increased due to the ongoing pandemic, but was not significantly high in the analysed population of older people. COVID-19-related anxiety was significantly more common in lonely individuals and in those of worse financial status. Women and men differed significantly in terms of perceived state anxiety and trait anxiety measured by STAI. More studies addressing COVID-19-related anxiety in older people participating in the Polish Universities of the Third Age are needed to determine a more accurate distribution of this phenomenon in Poland.

Corporate Social Responsibility (CSR) initiatives play an important starring role in changing the livelihoods of community members close to casinos around Gauteng. In addition, a contested industry such as gaming needs to ensure CSR initiatives are in place and communicated. The specific objective was to develop a CSR conceptual framework with guidelines for implementation in the casino industry using an Exploratory Factor Analysis (EFA). The study used quantitative research approach which involved eight casinos in Gauteng province, South Africa. Accidental sampling was used with a sample size of 385 with adjacent community members. Structured questionnaires were used as data collection instrument. The results indicated that social aspects and involvement, business and socio-environment, financial contribution, community basic services and food and nutrition are the basic initiatives to be incorporated in casino’s strategies and communicated to different stakeholders in order to improve community satisfaction, ideal public relations and gaining competitive advantage. Findings offer valuable cognizance in helping community members, Gauteng Gambling Board, CSR managers in casinos, employees and other interested stakeholders to review and evaluate the casinos’ CSR policies and implementation strategies.

An “unplanned excision” refers to soft tissue sarcomas excised without planning imaging studies and a diagnostic biopsy, resulting in the presence of residual disease and usually necessitating a re-excision procedure. We aimed to assess the impact of previous unplanned excisions on the intra-operative pathologic assessment at the time of re-excision, in terms of need to perform repeat assessments and the accuracy to predict margin status of the final pathologic specimen. Data was collected for all patients with extremity soft tissue sarcoma who had undergone wide local excision limb salvage surgery or amputation between 2012 and 2017. Intra-operative pathologic assessment with frozen sections was performed in all cases and was classified as negative, negative but close (
