Newborn hearing screening(NHS) programs are essential to identify hearing loss early in life and to improve outcomes in children. In Saudi Arabia, the national NHS program has been operational since 2016;however, few studies have evaluated its status, and none have covered all provinces across the country. This cross-sectional retrospective study provides an overview of the program's status across all provinces, focusing on screening coverage rates, referral/fail rates, and follow-up procedures. In 2021, 199,034 newborns were screened, with a coverage rate of 92.6% and an overall referral/fail rate of 1.87%. These performance measures provide a foundation for future progress and improvements. This study highlights the importance of ongoing efforts to enhance the program's effectiveness and sustainability.

Bullous pemphigoid (BP) is the most prevalent autoimmune sub-epidermal blistering disease that affects mainly the elderly and could lead to serious morbidity. It has numerous risk factors and triggers, including an aging population with several comorbidities and drug exposure. In the published paper, we reported a case about a 32 years old male patient with unknown medical conditions who presented with erythematous patches and plaques on the scalp, face, and trunk with scattered blisters two weeks after initiating doxycycline treatment for folliculitis. The exact pathogenesis of the drug-reaction in drug- associated bullous pemphigoid (DABP) remains controversial. In conclusion, it is crucial for clinicians to be aware of DABP when prescribing doxycycline. The purpose of this case report is to raise awareness of the possible association between bullous pemphigoid and doxycycline.

Real-time capabilities and computational efficiency are provided by parallel image processing utilizing OpenMP. However, race conditions can affect the accuracy and reliability of the outcomes. This paper highlights the importance of addressing race conditions in parallel image processing, specifically focusing on color inverse filtering using OpenMP. We considered three solutions to solve race conditions, each with distinct characteristics: #pragma omp atomic: Protects individual memory operations for fine-grained control. #pragma omp critical: Protects entire code blocks for exclusive access. #pragma omp parallel sections reduction: Employs a reduction clause for safe aggregation of values across threads. Our findings show that the produced images were unaffected by race condition. However, it becomes evident that solving the race conditions in the code makes it significantly faster, especially when it is executed on multiple cores.

Surface Electromyography(sEMG)plays a key role in many applications such as control of Human-Machine Interfaces(HMI)and neuromusculoskeletal modeling.It has strongly nonlinear relations to joint kinematics and reflects the subjects’intention in moving their limbs.Such relations have been traditionally examined by either integrated biomechanics and multi-body dynamics or gesture-based classification approaches.However,these methods have drawbacks that limit their usability.Different from them,joint kinematics can be continuously reconstructed from sEMG via estimation approaches,for instance,the Artificial Neural Networks(ANNs).The Comparison of different ANNs used in different studies is difficult,and in many cases,impossible.The current study focuses on fairly evaluating four types of ANN over the same dataset and conditions in proportional and simultaneous estimation of 15 hand joint angles from 10 sEMG signals.The presented ANNs are Feedforward,Cascade-Forward,Radial Basis Function(RBFNN),and Generalized Regression(GRNN).Each ANN is applied to its special parametric study.All the methods efficiently solved the regression problem of the complex multi-input multi-output bio-system.The RBFNN has the best performance over the others with a 79.80%mean correlation coefficient over all joints,and its accuracy reaches as high as 92.67%in some joints.Interestingly,the highest accuracy over individual joints is 93.46%,which is achieved via the GRNN.The good accuracy suggests that the proposed approaches can be used as alternatives to the previously adopted ones and can be employed effectively to synchronously control multi-degrees of freedom HMI and for general multi-joint kinematics estimation purposes.

Football is one of the most-watched sports,but analyzing players’per-formance is currently difficult and labor intensive.Performance analysis is done manually,which means that someone must watch video recordings and then log each player’s performance.This includes the number of passes and shots taken by each player,the location of the action,and whether or not the play had a successful outcome.Due to the time-consuming nature of manual analyses,interest in automatic analysis tools is high despite the many interdependent phases involved,such as pitch segmentation,player and ball detection,assigning players to their teams,identifying individual players,activity recognition,etc.This paper proposes a system for developing an automatic video analysis tool for sports.The proposed system is the first to integrate multiple phases,such as segmenting the field,detecting the players and the ball,assigning players to their teams,and iden-tifying players’jersey numbers.In team assignment,this research employed unsu-pervised learning based on convolutional autoencoders(CAEs)to learn discriminative latent representations and minimize the latent embedding distance between the players on the same team while simultaneously maximizing the dis-tance between those on opposing teams.This paper also created a highly accurate approach for the real-time detection of the ball.Furthermore,it also addressed the lack of jersey number datasets by creating a new dataset with more than 6,500 images for numbers ranging from 0 to 99.Since achieving a high perfor-mance in deep learning requires a large training set,and the collected dataset was not enough,this research utilized transfer learning(TL)to first pretrain the jersey number detection model on another large dataset and then fine-tune it on the target dataset to increase the accuracy.To test the proposed system,this paper presents a comprehensive evaluation of its individual stages as well as of the sys-tem as a whole.

Advances in the oncology field have led to improved survival rates.Consequently,quality of life after remission is anticipated,which includes the possibility to conceive children.Since cancer treatments are potentially gonadotoxic,fertility preservation must be proposed.Male fertility preservation is mainly based on ejaculated sperm cryopreservation.When this is not possible,testicular sperm extraction(TESE)may be planned.To identify situations in which TESE has been beneficial,a systematic review was conducted.The search was carried out on the PubMed,Scopus,Google Scholar,and CISMeF databases from 1 January 2000 to 19 March 2020.Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)recommendations were followed in selecting items of interest.Thirty-four articles were included in the systematic review,including 15 articles on oncological testicular sperm extraction(oncoTESE),18 articles on postgonadotoxic treatment TESE and 1 article on both oncoTESE and postgonadotoxic treatment TESE.Testicular sperm freezing was possible for 42.9%to 57.7%of patients before gonadotoxic treatment and for 32.4%to 75.5%of patients after gonadotoxic treatment,depending on the type of malignant disease.Although no formal conclusion could be drawn about the chances to obtain sperm in specific situations,our results suggest that TESE can be proposed before and after gonadotoxic treatment.Before treatment,TESE is more often proposed for men with testicular cancer presenting with azoospermia since TESE can be performed simultaneously with tumor removal or orchiectomy.After chemotherapy,TESE may be planned if the patient presents with persistent azoospermia.

Objective: COVID-19 has been significantly associated with both psychosocial stress and physiologic stress, both of which are known to trigger telogen effluvium. This study was performed to estimate the prevalence of hair loss among patients with COVID-19 and to determine the correlation of the severity of COVID-19 with the severity of hair loss.Methods: Data were collected through a self-administered electronic questionnaire that was distributed among social media platforms. Participants were invited to complete the survey using a convenience sampling technique. A multiple response dichotomies analysis and chi-square test of independence were used to analyze data.Results: Among 420 participants who reported a positive PCR result of SARS-CoV-2, 77.6% reported hair loss after COVID-19 development. Notably, the onset of hair loss was within 3 weeks of COVID-19 development in 29% of participants. Most of the participants reported that the duration of hair loss was up to 6 months, and hair regrowth was noticed within 1 year after COVID-19 development. Patients who were admitted to the hospital, who experienced respiratory difficulties, who had lost weight due to COVID-19, and who experienced symptoms for longer than 10 days were significantly more prone to experience severe hair loss following COVID-19 (P < 0.001).Conclusion: This study demonstrated a high frequency of self-reported hair loss after the development of COVID-19. Interestingly, even patients with mild COVID-19 symptoms were significantly more prone to experience moderate hair loss. Unique to COVID-19 infection, the onset of hair loss following the development of COVID-19 was within 3 weeks in one-third of the participants.

Cellulose nanocrystal(CNC)is a biomaterial derived from plant lignocellulosic components,widely applied in various industrial fields.Concurrently,with the growth of awareness in developing green nanomaterial,the explored Washingtonia fibre could be alternative biomass for obtaining CNC products.In the present work,different acid concentrations of 5%,15%,and 25%hydrochloric solutions were employed to produce CNCs from Washingtonia fibre.With the chemical treatments,the yield of the CNC product was successfully retained at 21.6%-25.1%.Individually separated and needle-shaped CNC particles could be observed under the microscopic viewing with the increased acid concentrations.From elemental analysis,a relatively pure cellulose compartment was produced for all CNC samples.The zeta potential values between-10 to-16 mV proved that each nanoparticle sample possessed dispersion ability within an aqueous solution.Meanwhile,the degree of crystallinity and the thermal behavior of CNCs were enhanced with the increased acidic concentrations.Hence,the isolated CNCs(with 15%)from Washingtonia fibre lead a CNC with the highest aspect ratio(30).This parameter is so important that these structures show empowering points of view as nanomaterials for reinforced polymer composites,and it could be a reliable nano-filler for the composite fabrication process in the future.
