Knowledge and Awareness Regarding Bell's Palsy in the Al-Qassim Region, Saudi Arabia

Introduction: Bell's palsy, characterized by acute onset unilateral facial weakness, is caused by the paralysis of the seventh cranial nerve, which controls the muscles of the face. This condition can result in functional disabilities, and early detection and management are crucial for quick recovery. Awareness was found to be one of the factors associated with early detection and interventions. Therefore, this study aimed to assess the awareness of the population of Al-Qassim, Saudi Arabia, regarding Bell's palsy.

METHODS

We conducted a cross-sectional study on 1,198 participants in Al-Qassim, Saudi Arabia, between May and July 2023. We used a self-administered online questionnaire inquiring about knowledge and awareness of Bell's palsy. We performed descriptive and correlation analyses, and a p-value of less than 0.05 indicated a statistical significance.

RESULTS

The mean (± SD) knowledge score was 7.02 ± 2.03 out of a total of 13 points. Almost a third of participants (n=353, 29.5%) expressed uncertainty about the causes of Bell's palsy, with 346 (28.9%) and 107 (8.9%) attributing it to idiopathic factors and viral infections, respectively. Most participants (n=520, 43.4%) believed both genders were equally affected, while 563 (46.9%) correctly identified cranial nerve 7 as the affected nerve. Treatment awareness varied, with 629 (58.2%) acknowledging physiotherapy and (n=777, 64.9%) acknowledging traditional medicine. Interestingly, only 111 (9.3%) thought that Bell's palsy was permanent, most participants (n=1023, 85.4%) recognized Bell's palsy as treatable, and 1,105 (92.2%) correctly perceived it as non-contagious. There were significant correlations between awareness and age (p<0.001), gender (p<0.001), marital status (p<0.001), occupation (p<0.001), information source (p<0.001), nationality (p=0.009), and education levels (p<0.031). Addressing these gaps and demographic nuances through targeted educational campaigns is crucial for enhancing overall awareness of Bell's palsy.

CONCLUSION

These findings indicate suboptimal awareness among participants in general, poor knowledge about causes and clinical manifestation, and a relatively better awareness of treatments. We recommend further studies exploring awareness and associated factors.

Musculoskeletal Disorders and Their Impact on Job Performance Among School Teachers in Buraydah City

INTRODUCTION

Musculoskeletal disorders (MSD) pose a significant challenge to the well-being and productivity of individuals and various occupational groups, including teachers. Among teachers, the prevalence of MSD has raised concerns globally, impacting their daily activities and overall quality of life. Buraidah and Saudi Arabia, like many other regions, face the implications of this issue. This study aimed to explore the prevalence and associated risk factors of MSD among teachers in Buraydah, providing valuable insights into the extent of the problem and potential areas for intervention.

METHODOLOGY

 An analytic cross-sectional study was conducted for three months, from April 1 to June 30, 2023, using the Arabic version of the standardized Nordic Musculoskeletal Disorder Questionnaire. This study was conducted in all schools in Buraydah City, Saudi Arabia. The study population was all schoolteachers (including principals, vice principals, etc.) in Buraydah City. The study analyzed responses from 648 teachers and 139 school workers using statistical tests, including chi-square tests and logistic regression models.

RESULTS

 The results indicated a notable prevalence of MSD among teachers, with a significant association found between age, gender, and major depressive disorder (MDD) and MSD. The study reveals that females are at higher risk of MSD compared to males, emphasizing the need for gender-specific interventions. Moreover, the presence of MDD is identified as a significant contributor to MSD among teachers. However, certain demographic and lifestyle factors, such as marital status, level of school, smoking habits, and fixed rest times, do not show significant associations with MSD. Although age and years of experience are correlated, only age is found to significantly contribute to MSD. Regular exercise and BMI also do not emerge as significant contributors, although a lack of exercise shows a marginal impact.

CONCLUSION

 This study's findings have implications for educational institutions and policymakers, highlighting the need for tailored interventions to address MSD among teachers. It underscores the importance of ergonomic interventions, gender-sensitive approaches, and mental health support.

Perceived stress and resilience levels during the COVID-19 pandemic among critical care nurses in Saudi Arabia: a correlational cross-sectional study

Background

The continuous spreading of the respiratory coronavirus disease, COVID-19, has been a threat to global health, especially among those fighting directly against it. Nurses who work in critical care have reported very high levels of stress during these extreme circumstances. It is very important to measure the level of stress and resilience among these nurses in order to diminish further psychological distress. This study aims to assess the levels of perceived stress and resilience among critical care nurses.

Methodology

In this correlational cross-sectional study, critical care nurses (n = 139) were recruited by gatekeepers in a governmental university hospital in Riyadh City between 12 March and 8 April 2021 to complete an online questionnaire. The measurement tools used in this study were the Connor-Davidson Resilience Scale 10 (CD-RISC-10) and the Perceived Stress Scale of COVID-19 (PSS-10 items). Data were analyzed using a descriptive and inferential analysis to calculate frequencies to determine the distribution of stress and resilience, and multiple regression was applied to assess the relationship between them.

Results

One hundred and thirty-nine critical care nurse (64%) responded. The perceived levels of stress reported were: no stress (8%; n = 12), mild stress (14%; n = 21), moderate stress (38%; n = 55), high stress (22%; n = 32), and severe stress (18%; n = 26). The levels of resilience reported were: very low (8%; n = 11), low (18%; n = 26), moderate (42%; n = 62), and high (32%; n = 47). The level of stress and resilience reported by the majority of critical care nurses was moderate; there was no significant correlation between COVID-19-related stress and resilience among the critical care nurses. Severe levels of stress were mostly reported among critical care nurses working in the NICU and high levels of stress were reported among those working in the emergency department. The nurses reported being highly confident that they were able to handle personal epidemic related problems with a mean score of 2.36. This reflects having a high level of resilience (42%; n = 62) and was significantly associated with years of experience as a nurse (p < 0.0027).

Conclusion

Although COVID-19 cases had declined significantly during the study period in Saudi Arabia, the majority of nurses were still experiencing moderate to high levels of stress about the epidemic, but were, at the same time, moderately resilient. Continued monitoring of the stress levels of this high-risk group is highly essential. Conducting more research is needed to measure the effectiveness of psychosocial support interventions.

A novel and simple test of gait adaptability predicts gold standard measures of functional mobility in stroke survivors

BACKGROUND

Although there is evidence that stroke survivors have reduced gait adaptability, the underlying mechanisms and the relationship to functional recovery are largely unknown. We explored the relationships between walking adaptability and clinical measures of balance, motor recovery and functional ability in stroke survivors.

METHODS

Stroke survivors (n=42) stepped to targets, on a 6m walkway, placed to elicit step lengthening, shortening and narrowing on paretic and non-paretic sides. The number of targets missed during six walks and target stepping speed was recorded. Fugl-Meyer (FM), Berg Balance Scale (BBS), self-selected walking speed (SWWS) and single support (SS) and step length (SL) symmetry (using GaitRite when not walking to targets) were also assessed. Stepwise multiple-linear regression was used to model the relationships between: total targets missed, number missed with paretic and non-paretic legs, target stepping speed, and each clinical measure.

RESULTS

Regression revealed a significant model for each outcome variable that included only one independent variable. Targets missed by the paretic limb, was a significant predictor of FM (F(1,40)=6.54, p=0.014,). Speed of target stepping was a significant predictor of each of BBS (F(1,40)=26.36, p<0.0001), SSWS (F(1,40)=37.00, p<0.0001). No variables were significant predictors of SL or SS asymmetry.

DISCUSSION

Speed of target stepping was significantly predictive of BBS and SSWS and paretic targets missed predicted FM, suggesting that fast target stepping requires good balance and accurate stepping demands good paretic leg function. The relationships between these parameters indicate gait adaptability is a clinically meaningful target for measurement and treatment of functionally adaptive walking ability in stroke survivors.

Seasonality and prevalence of rotavirus in Al-Ain, United Arab Emirates

Background: Rotaviruses are the single most important causative agent of acute neonatal enteritis in most avian and mammalian species including humans. Rotaviruses infections have also been shown to be associated with the elderly, immunocompromised individuals and more recently with epidemic diarrheal illness in adults.

Objectives: To study the incidence and the effect of seasonality on the prevalence of rotaviruses in Al-Ain, United Arab Emirates.

Study design: A total of 650 stool samples submitted to the laboratories of two University Teaching Hospitals (Al-Ain and Tawam) and a private hospital (Oasis) were examined for the presence of rotaviruses from January 1990–December, 1992, using a commercially available latex agglutination assay. The meteorological data (temperature, relative humidity and rainfall) recorded during the sampling period was analyzed statistically to examine the effect of seasonality on the prevalence of rotavirus cases in Al-Ain, United Arab Emirates.

Results: Rotavirus was detected in 21.4% of the samples examined. The predominant number of positive cases (35%) were in the 7–12 months age group. It was interesting to find rotavirus-positive cases in as low an age group as <3 months (3.6%) and as high as 10 years (8.04%). There was no significant difference on infection rates between male and female groups in the study. However, there was a significant difference between the national (38.18%) and non-national children (61.28%). The higher rate of the latter may be due to import of infections. There appeared to be a seasonal pattern of rotavirus occurrence in the cases studied, with a marked increase in the number of positive cases during the months when the relative humidity was low (25–45%) and there was no rainfall.

Conclusions: Rotavirus was detected in all age groups with a predominance in 7–12 month age groups, and a higher incidence in non-nationals. There was a marked increase in the number of positive cases during the months when the relative humidity was low (25–45%) and there was no rainfall. These findings are discussed in relation to the epidemiology and prophylaxis of rotavirus infections.

Suppression of transplant immunity in experimental trichinellosis

Skin allograft rejection in Balb/c and C57BL/6J mice following experimental infection with 300 larvae of Trichinella spiralis or Trichinella pseudospiralis was studied. Skin grafts from normal C57BL/6J mice were transplanted to infected Balb/c mice and vice versa at days 3, 10, 20 and 30 post-infection. The clinical criteria for graft rejection, scarring and graft falling, were followed. The results indicated that T. spiralis and T. pseudospiralis infections induced a significant delay in graft rejection when compared to the control groups. A maximum rejection time of 24 days was observed in T. spiralis infected C57BL/6J mice which received skin grafts from Balb/c mice on day 3 post-infection. The rejection in the uninfected control group was on day 7 post transplant. The mean rejection times for transplants on various days post-infection, with both species were very similar. Also, the rejection profiles in Balb/c mice were comparable to that observed in C57BL/6J mice, with a maximum delay of 26 days to rejection again obtained in mice transplanted on day 3 post-infection, for both species. When the skin grafts were performed 5 or 10 days prior to infection, the rejection occurred on day 7, as in the control group. The effect of T. spiralis and T. pseudospiralis soluble larval extracts (TSE or TPE) on graft rejection was also examined. Four intraperitoneal injections of 50 micrograms each of TSE or TPE every 48 h for 7 days did not induce any significant delay in graft rejection. In contrast, secretory antigens prepared from cultured larvae in vitro induced significant delays in graft rejection.(ABSTRACT TRUNCATED AT 250 WORDS)

Studies on the rate of selective uptake of amino acids by Trichinella larvae in vivo

Groups of C57BL/6J mice, orally infected with 300 larvae each of Trichinella spiralis or T. pseudospiralis were injected with [3H]-alanine, tyrosine, tryptophan or glycine. The incorporation of isotope labelled amino acids into larval proteins was measured at 2, 6, and 12 months post-infection. It was shown that there is a significant increase in the in vivo uptake of isotope labelled amino acids with time by the larvae of T. spiralis and T. pseudospiralis. The level of uptake was highest for tyrosine followed by tryptophan, alanine and then glycine, for both species. The in vivo uptake of amino acids by T. pseudospiralis larvae was always higher than T. spiralis or the host at 6 and 12 months post-infection. At 2 months post-infection, T. spiralis uptake of these amino acids was higher, except for tyrosine. This may be related to the special needs of these larvae during the process of encystation. The higher metabolic requirements of T. pseudospiralis may be related to the higher energy needs of these non encapsulated, highly motile and mobile muscle larvae.
