Prevalence of Chronic Pain After Spinal Surgery: A Systematic Review and Meta-Analysis.

Degenerative disc disease and low back pain are common challenges that persist even after a discectomy. However, characterizations and quantifications of these illnesses from the patients' perspective are insufficient. We aimed to perform a systematic review of the literature and meta-analysis to determine the frequency of chronic pain after spinal surgery. We searched MEDLINE (PubMed), Google Scholar, and the Saudi Digital Library to retrieve research articles describing the frequency of persistent back pain, reoccurring disc herniation, and undergoing another operation following primary lumbar discectomy. We excluded articles that did not disclose the proportion of patients who experienced ongoing back or leg pain for over six months after the operation. We included 16 studies evaluating 85,643 patients. The pooled prevalence of persistent pain was 14.97% (95% confidence interval: 12.38-17.76). With all advancements in technology and operation techniques, many patients (14.97%) still have failed back surgery syndrome. Appropriate preoperative communication and multidisciplinary and coordinated treatment strategies yielded the best results.

Frequency and predictive factors for spontaneous normalization of anti-tissue transglutaminase-IgA serology among Saudi children with type 1 diabetes mellitus: A cohort study.

Background: Celiac serology can be transiently elevated in patients with type 1 diabetes mellitus (T1DM) and normalized despite gluten consumption. This study aimed to identify the frequency and predictive factors of spontaneous normalization of anti-tissue transglutaminase (anti-TTG-IgA) antibodies in these patients. Methods: The charts of all patients (≤18 years) with T1DM were retrospectively reviewed from 2012 to 2021 at a tertiary care center in Riyadh, Saudi Arabia. The following data were collected: clinical characteristics of the participants, anti-TTG-IgA-immunoglobulin (Ig) A antibody, and histological findings. The outcome of positive anti-TTG-IgA-IgA in patients with T1DM and the predictive factors for spontaneous normalization were investigated. Results: Of the 1,006 patients with T1DM, 138 (13.7%) had elevated anti-TTG-IgA antibodies, celiac disease was diagnosed in 58/138 (42%) patients, spontaneous normalization of anti-TTG-IgA was observed in 65 (47.1%) patients, and fluctuating anti-TTG-IgA antibodies were seen in 15 (10.9%) patients. The patients with anti-TTG-IgA levels at 3-10 times the upper normal limits (UNL), and those with levels ≥10 times UNL were less likely to have spontaneous normalization of anti-TTG-IgA compared to patients with levels at 1-3 times UNL (hazard ratio [HR] = 0.28, 95% confidence interval [Cl] = 0.13-0.61, P = 0.001, and HR = 0.03, 95% Cl = 0.00-0.19, P < 0.001, respectively). Conclusion: Asymptomatic patients with T1DM with mild elevation of anti-TTG-IgA need not be rushed for invasive endoscopy or exposed to an un-needed gluten-free diet but should rather have a regular follow-up of their celiac serology.

Microbial surveillance of Hajj tents: Bioaerosol sampling coupled with real-time multiplex PCR.

BACKGROUND: Respiratory tract infections are common among pilgrims attending annual Hajj in Mecca, Saudi Arabia. Pilgrims typically spend most of the Hajj period inside ventilated tents, where microorganisms may be transmitted through bioaerosols and droplets. OBJECTIVE: To perform microorganism surveillance inside Hajj tents and assess the similarities between microorganisms isolated from tent bioaerosol samples and nasopharyngeal swabs (NP) of tent occupants. METHODS: Respiratory microorganisms in bioaerosols collected from Hajj tents over a 4-day period were compared with NP of tent occupants using real-time multiplex polymerase chain reaction analysis. RESULTS: A total of 152 samples were collected: 120 tent bioaerosol samples collected on days 9, 10, 11, and 12 of Dhu al-Hijjah, and 32 NP collected on day 12 of Dhu al-Hijjah (corresponding to 23/08/2018). Eighty-three (69.2%) bioaerosol samples tested positive for at least 1 microorganism, with the number of pathogens increasing over the 4 days of sampling. Twenty-seven (84.38%) NP swabs from tent occupants also tested positive. Microorganisms identified in pilgrim nasal carriage and tent bioaerosol samples were similar, and included K. pneumonia, S. aureus, S. pneumonia, human adenovirus, Moraxella, influenza A, and H. influenza. CONCLUSIONS: The data suggest that the Hajj tent environment may contribute to the spread of airborne infections during Hajj. This can have important ramifications for novel pathogens with pandemic potential.

Prevalence and the Associated Factors of Erectile Dysfunction Among Saudi Married Males.

OBJECTIVES: To estimate the prevalence of erectile dysfunction (ED) and to determine the associated factors of erectile dysfunction among Saudi married male subjects. METHODS:  A cross-sectional study based on data collected from 313 male subjects. The questionnaire was given to the randomly selected subjects from the appointment list in KKUH outpatient clinics using a simple random sampling method. The study questionnaire included the following sections: demographic, lifestyle, and medical history. The international index of erectile function-15 (IIEF-15) scale was used to assess ED. Statistical analyses were done using Statistical Package for Social Sciences (SPSS, IBM Corp., Armonk, NY, USA). RESULTS:  Out of 313 participants 33 had ED (10.53%). The associated factors were age (odds ratio= 14.4), lower education level (odds ratio= 15.85), mild physical activity (odds ratio= 7.69), and medical conditions like diabetes mellitus, hypertension, and hypercholesteremia (odds ratio= 3.6). CONCLUSION:  The diagnosis of ED in Saudi Arabia is underestimated and services for the diagnosis and treatment should be provided for diabetes, hypertension, hypercholesteremia and elderly patients.

Beverage Consumption and Ulcerative Colitis: A Case-Control Study from Saudi Arabia.

BACKGROUND: The association between beverage intake and ulcerative colitis (UC) is not well-established, with no available data from Arab countries. Herein, we investigated the potential association of consuming coffee, tea, and carbonated soft drinks with UC among a population from Saudi Arabia. METHODS: This hospital-based case-control study used data of 171 newly diagnosed UC patients and 400 patients with other gastrointestinal conditions who served as controls. All UC cases were ascertained by endoscopy, while beverage intake was assessed by a questionnaire that was completed before diagnosis. We computed odds ratios (ORs) and 95% confidence intervals (95% CIs) of UC and UC extension for frequent versus infrequent intakes of coffee, tea, and carbonated soft drinks using logistic regression. RESULTS: Overall, 23.4% of UC patients had pancolitis, 21.1% extensive, 51.4% left-sided, and 4.1% proctitis. UC patients had a similar sex distribution to the controls but were older and had a lower BMI. After adjustment for age, sex, body mass index, and smoking history, frequent intakes of coffee and tea were associated with lower odds of UC: 0.62 (0.42, 0.91) and 0.53 (0.35, 0.79), respectively. On the other hand, frequent intakes of carbonated soft drinks were associated with increased odds of UC: 9.82 (6.12, 15.76). The frequency of beverage consumption was not associated with UC extension. CONCLUSION: UC was negatively associated with frequent coffee and tea consumption but positively associated with frequent carbonated soft drink intake in Saudi people. More population-based prospective cohort studies are needed to confirm our findings.

Long-Term Weight Outcomes after Bariatric Surgery: A Single Center Saudi Arabian Cohort Experience.

BACKGROUND: Obesity is considered a global chronic disease requiring weight management through lifestyle modification, pharmacotherapy, or weight loss surgery. The dramatic increase in patients with severe obesity in Saudi Arabia is paralleled with those undergoing bariatric surgery. Although known to be beneficial in the short term, the long-term impacts of surgery within this group and the sustainability of weight loss after surgery remains unclear. OBJECTIVES: We aimed to assess the long-term weight outcomes after bariatric surgery. SETTING: The study was conducted at King Khalid University Hospital (KKUH), King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia. METHODS: An observational prospective cohort study on adult patients with severe obesity undergoing bariatric surgery (sleeve gastrectomy (SG) or Roux-en Y gastric bypass (RYGB)) during the period between 2009 and 2015 was conducted. Weight loss patterns were evaluated pre- and post-surgery through clinical and anthropometric assessments. Absolute weight loss was determined, and outcome variables: percent excess weight loss (%EWL), percent total weight loss (%TWL), and percent weight regain (%WR), were calculated. Statistical analysis using univariate and multivariate general linear modelling was carried out. RESULTS: A total of 91 (46 males and 45 females) patients were included in the study, with the majority belonging to the SG group. Significant weight reductions were observed at 1 and 3 years of follow-up (p < 0.001) from baseline. The %EWL and %TWL were at their maximum at 3 years (72.4% and 75.8%) and were comparable between the SG and RYGB. Decrements in %EWL and %TWL and increases in %WR were seen from 3 years onwards from bariatric surgery until the study period ended. The yearly follow-up attrition rate was 20.8% at 1 year post-surgery, 26.4% at year 2, 31.8% at year 3, 47.3% at year 4, 62.6% at year 5, and 79.1% at end of study period (at year 6). CONCLUSION: The major challenge to the successful outcome of bariatric surgery is in maintaining weight loss in the long-term and minimizing weight regain. Factors such as the type of surgery and gender need to be considered before and after surgery, with an emphasis on the need for long-term follow-up to enssure the optimal benefits from this intervention.

The Prevalence of C-Section Delivery and Its Associated Factors Among Saudi Women Attending Different Clinics of King Khalid University Hospital.

Objective Cesarean section (C-section) is one of the most common surgical procedures worldwide that may be performed to deliver one or more newborns. The objective of our study was to determine the prevalence of C-section delivery among Saudi women attending different clinics of King Khalid University Hospital (KKUH) who were pregnant, previously pregnant, and had delivered. Methods A quantitative observational cross-sectional study using a self-administered questionnaire that has been handed to the participants after explaining the purpose of the study. A total of 524 pregnant and non-pregnant women were enrolled in the study randomly collected from all female clinics of KKUH. The study sample were given a self-administered questionnaire. Data were analyzed using the Statistical Package for Social Sciences (SPSS), version 21 (IBM SPSS Statistics, Armonk, NY) to analyze the data. Results Of the 524 study participants, 32.6% underwent C-section. There was a statistical significance in women aged 23 years old, as well as teachers, in relation to undergoing C-section (p-values = 0.0001 and 0.044, respectively). We concluded that malpresentation is the most common medical indication, with an overall percentage of 25%. There was no evident statistical association between body mass index (BMI), the highest level of education, marital status, Income status, mode of delivery, and the number of normal births or stillbirths. Conclusion It was found that the prevalence of Saudi women attending KKUH who underwent C-section was 32.6%. Medical indications to undergo C-sections, in comparison to the non-medical ones, were higher. Malpresentation was the most common medical indication, with an overall percentage of 25%.

Perceptions, attitudes, and barriers toward obesity management in Saudi Arabia: Data from the ACTION-IO study.

BACKGROUND: The ACTION IO study (NCT03584191) aimed to identify perceptions, attitudes, behaviors, and potential barriers to effective obesity care across people with obesity (PwO) and healthcare professionals (HCPs). Results from Saudi Arabia are presented here. METHODS: A survey was conducted from June to September 2018. In Saudi Arabia, eligible PwO were ≥18 years with a self reported body mass index of ≥30 kg/m2. Eligible HCPs were in direct patient care. RESULTS: The survey was completed by 1,000 PwO and 200 HCPs in Saudi Arabia. Many PwO (68%) and HCPs (62%) agreed that obesity is a chronic disease. PwO felt responsible for their weight management (67%), but 71% of HCPs acknowledged their responsibility to contribute. Overall, 58% of PwO had discussed weight with their HCP in the past 5 years, 46% had received a diagnosis of obesity, and 44% had a follow up appointment scheduled. Although 50% of PwO said they were motivated to lose weight, only 39% of HCPs thought their patients were motivated to lose weight. Less than half of PwO (39%) and HCPs (49%) regarded genetic factors as a barrier to weight loss. Many PwO had seriously attempted weight loss (92%) and achieved ≥5% weight loss (61%), but few maintained their weight loss for >1 year (5%). CONCLUSION: Saudi Arabian results have revealed misperceptions among PwO and HCPs about obesity, highlighting opportunities for further education and training about obesity including the biologic basis and clinical management.

Prevalence of Premenstrual Syndrome Levels and Its Management Among Female Students of Medical and Non-Medical Colleges in Riyadh.

Objective The purpose of this study is to measure the prevalence of premenstrual syndrome (PMS), its management, and its possible association with depression, anxiety, and stress among female medical and non-medical students. Methods A cross-sectional study was conducted at King Khalid University Hospital and King Saud University Female Campus. A self-administered questionnaire following the American College of Obstetricians and Gynecologists (ACOG) criteria was used to measure levels of PMS. It also included the Depression Anxiety Stress Scale (DASS) to measure depression, anxiety, and stress. The inclusion criteria were: females of reproductive age who had menstrual cycles for two consecutive months. Meanwhile, the exclusion criteria included gynecological or psychological problems, pregnancy, and the use of oral contraceptive pills. Of the 513 responses, 414 met the above criteria and were used in the study. An analysis was done using the Statistical Package for the Social Sciences (SPSS, version. 21.0, IBM Armonk, NY). To compare the mean values of quantitative variables, the student's t-test for independent samples was used. Accordingly, Pearson's correlation quantified the linear relationship between the two quantitative variables. Results The majority of female students have a moderate level of PMS, and only 8% have severe PMS. Notably, 8.9% of the students have moderate anxiety while 1.7% and 0.7% have severe and extremely severe anxiety, respectively. Moreover, 11.8% and 3.4% of the students have moderate depression and stress, respectively, whereas 1.7% have severe depression. The results show a positive correlation between PMS and anxiety, depression, and stress. Depression and stress scores vary significantly between medical and non-medical students. Conclusion Premenstrual syndrome is a prevalent issue among females, and it can negatively affect their health. There is a need to study PMS thoroughly to optimize and guide its management for further improving women's health.

Prevalence of self-reported computer vision syndrome symptoms and its associated factors among university students.

PURPOSE: To determine the prevalence of symptoms of computer vision syndrome and to identify its associated factors. The secondary objective was to assess knowledge and practices related to preventing computer vision syndrome symptoms. METHODS: The data for this cross-sectional study were collected through a self-administered questionnaire distributed to 713 female undergraduates studying business and medicine in Saudi Arabia. The questionnaire included computer vision syndrome validated symptoms and factors associated with computer vision syndrome development. RESULTS: The most common symptom due to prolonged computer use was neck or shoulder pain, reported by 82.2% of the subjects. Overall, 66.5% of the subjects suffered from headache and 51.5% from dry eyes, in mild, moderate, or severe form. Business students were 1.6 times as likely as medical students to suffer from computer vision syndrome (odds ratio = 1.65; 95% confidence interval: 1.22, 2.24). The use of electronic devices for more than 5 h (odds ratio = 1.52; 95% confidence interval: 1.07, 2.16) was also associated with experiencing computer vision syndrome symptoms. Regarding computer vision syndrome prevention, factors such as hours of use, screen distance, screen brightness, and room illumination showed statistically significant difference between the two groups (p < 0.0001). CONCLUSION: The prevalence of computer vision syndrome symptoms was significantly higher among business students, who reported lower awareness and poor practice measures of computer use recommendations. Relevant awareness campaigns focusing on the appropriate use of computers are highly recommended.

Treatment Adherence Among Patients with Five Dermatological Diseases and Four Treatment Types - a Cross-Sectional Study.

PURPOSE: Treatment non-adherence leads to negative therapeutic outcomes and financial burdens on the healthcare system. This study aims to compare the mean adherence scores among patients with five dermatological diseases and four treatment types and to identify the associated patient-related factors. PATIENTS AND METHODS: This is a cross-sectional study conducted from January 2019 to August 2019. The questionnaire was distributed among patients attending the outpatient dermatology clinic at King Khalid University Hospital, Riyadh, Saudi Arabia. It included 2330 patients who were over 16 years old and diagnosed with any of the five dermatological diseases (psoriasis, chronic dermatitis, acne vulgaris, hair growth disorders, and vitiligo). The 12-item Medication Adherence Scale was used to quantify the mean adherence score. RESULTS: Patients with psoriasis or chronic dermatitis were less adherent to treatments than patients with acne vulgaris, hair growth disorder, or vitiligo. Oral treatment and phototherapy had higher mean adherence scores than injection or topical treatment. High adherence was found in female, single patients; those who did not feel stigmatized from using treatment; those who did not have bad experience with the treatment; those who did not suffer from forgetfulness; those who connected receiving treatment with a habit; those who did not lack treatment responsiveness; those who had an excellent relationship with a dermatologist; and patients with a lesion in an exposed area. Stepwise multiple linear regression was also used to identify the independent variables related to adherence score. CONCLUSION: Psoriasis and chronic dermatitis patients had the lowest mean adherence scores. Patient who were on oral medication had the highest adherence score, while those on topical medication had the lowest score. The thoughtful consideration of factors associated with high adherence is important for optimal therapeutic outcomes.

Vascular sclerosing effects of bleomycin on cutaneous veins: a pharmacopathologic study on experimental animals.

BACKGROUND:: Varicose veins and the complications of venous disease are common disorders in humans. OBJECTIVE:: To study the effects of bleomycin as a potential new sclerosing agent and its adverse events in treating varicose veins. METHODS:: Bleomycin-loaded liposomes 0.1ml was injected in the dorsal ear veins of white New Zealand rabbits. Sodium tetradecyl sulfate was used as a positive control. Normal saline was used as negative control. The blood vessels of the treated ears were photographed before and at one hour and two, eight and 45 days after treatment. Biopsies from the treated areas were obtained for histological examination. Blood samples were collected to determine any possible toxicity. RESULTS:: Bleomycin by itself was ineffective; therefore, liposomes were used as a vector to deliver bleomycin to the vein lumen. Subsequently, bleomycin started showing its sclerosing effects. Toxicity monitoring showed no apparent hematologic, pulmonary, hepatic or renal toxicities. This study revealed that bleomycin induced vasculitis, which led to vascular occlusion, which was observed on day 1 and day 8. No bleomycin-related injury was noted by histopathological examination of lung sections. The calculation of the lung/body weight coefficient indicated that edema was present in the experimental groups compared with the negative and positive controls. STUDY LIMITATIONS:: Relatively small number of experimental animals used. CONCLUSIONS:: This study showed that bleomycin-loaded liposomes were able to induce vasculitis and vascular occlusion without any toxicity or complications. It might be useful, hence, to treat patients suffering from Varicose veins and other ectatic vascular diseases with this agent.
