Assessment of the services provided at the family medicine staff clinics in King Saud Medical City, Riyadh.

Background: Patient satisfaction is the subjective evaluation of a patient's cognitive and emotional responses. This reflects their expectations regarding the ideal healthcare to be provided. This study aims to assess the satisfaction level of the attendees to the family medicine staff clinics at King Saud Medical City, Riyadh. Materials and Methods: A descriptive cross-sectional study recruited 378 participants. An adapted and piloted questionnaire was used to gather the data. The questionnaire enquires about the communication skills of the receptionist, the triage nurse, and the assigned physician. It included questions regarding the structure of the clinics. Results: Females represent the majority of about 255 (67.5%). About 2/3 of the respondents were within the age group of 18-34 years, 245 (64.8%). A high level of satisfaction was reported by the participants regarding the professionalism, kindness, interest of the staff member, and waiting time. Gender, marital status, and age group have no significant effect on the satisfaction level; the P value was uniformly more than 0.05. Conclusion: The result of this study identified high satisfaction responses regarding the communication skills of the receptionist, triage nurse, and physicians. The overall evaluation of the experience during staff clinic visits was satisfactory. Periodic evaluation of these attributes and other indicators that promote patient-centered care should be undertaken to improve the overall quality of care.

A challenging diagnosis of spinal epidural lipomatosis: A case report and review of the literature.

INTRODUCTION: Spinal Epidural Lipomatosis (SEL) is a rare disorder of pathological overgrowth of the spinal epidural fat in the extradural space. The pathogenesis of SEL usually involves exogenous steroid use or endogenous steroids overproduction. However, idiopathic cases have been reported. Magnetic resonance imaging (MRI) is the gold standard for diagnosis. Both conservative and surgical approaches are employed in management of these patients. CASE PRESENTATION: A 17-year-old male presented to our hospital complaining of progressive lower limb weakness, loss of sensation with urinary incontinence which ended up with paraplegia. He underwent extensive investigations and received multiple inaccurate diagnoses. MRI of the thoracic spine showed spinal epidural lipomatosis with dorsal kyphosis. Hemi-laminectomy for spinal cord decompression and trans-pedicular fixation for correction of kyphosis were performed showing excellent outcomes. CLINICAL DISCUSSION: Diagnosing SEL can be challenging due to its symptom overlap with other neurological conditions. Thus, higher levels of clinical suspicions and utilization of numerous diagnostic modalities including MRI are required. Treatment is largely determined by the clinical presentation and the severity of symptoms. Given the severity of neurological symptoms in our case, surgical intervention was performed resulting in fully regained functionality of previously paralyzed muscles. CONCLUSION: This case highlights the rare presentation and the diagnostic challenges of spinal epidural lipomatosis SEL in a young patient who was misdiagnosed for 9 consecutive months before receiving the correct diagnosis, emphasizing the importance of considering SEL in the differential diagnosis for progressive neurological deficits and the importance of MRI, especially in atypical cases.

Acute coronary syndrome in young (≤45 years) patients: a multi-centre observational study.

Introduction: Acute coronary syndrome (ACS) in young individuals (≤45 years) is increasingly recognized as a significant health concern, yet research in this demographic remains limited, particularly within the Palestinian context. This study aims to bridge this gap by comprehensively investigating the clinical characteristics, age-specific profiles, gender disparities, treatment modalities, and angiographic patterns of ACS in young patients compared to their older counterparts. Materials and methods: A multi-centre observational study was conducted, enroling 468 participants aged 18-55 diagnosed with ACS and admitted to three prominent Palestinian hospitals. Data were collected from medical records, and statistical analysis was performed to assess demographic characteristics, clinical presentations, risk factors, treatment strategies, and outcomes. Results: The majority of participants were male (87%), with a higher proportion in the older age group (>45 years). Clinical presentations varied, with non-ST segment elevation myocardial infarction (NSTEMI) being the most common diagnosis (48%). Risk factors such as smoking, hypertension, and diabetes were prevalent, with notable gender and age-specific differences. Percutaneous coronary intervention (PCI) was the predominant treatment strategy (83%), with consistent medication use across age groups. Conclusion: ACS in young patients poses a significant public health challenge in Palestine, necessitating tailored preventive strategies and comprehensive management approaches. Understanding the unique demographic and clinical characteristics of young ACS patients is crucial for informing targeted interventions and policies aimed at reducing the burden of cardiovascular disease in this population. These findings contribute valuable insights to the existing literature and underscore the importance of further research in this area to improve outcomes and mitigate the impact of ACS in young individuals globally.

Pilomatrix carcinoma of the lower extremity: A rare case report and literature review.

INTRODUCTION: Pilomatrix carcinoma (PC) is a rare skin malignancy of the hair follicles matrix that tends to be locally aggressive with 10-16 % risk of metastasis mostly to the pulmonary and lymphatic system. There are no clear protocols for the management of PCs, however surgical intervention with clear margins has been highly considered in PC management to decrease risk of recurrence. CASE PRESENTATION: A 40 year-old male patient presented to our clinic to evaluate an asymptomatic, slow-growing nodule localized on his left thigh. A CT scan revealed a well-defined, enhanced lesion with microcalcification. "En bloc" surgical resection of the lesion was performed and histopathology confirmed the diagnosis of pilomatrix carcinoma. CLINICAL DISCUSSION: Given its rarity, there are no definitive guidelines regarding PC treatment. However, surgical intervention with clear margins including wide local excision or Mohs micrographic surgery has been highly considered. In our case, wide excision of the lesion with clear margins was performed with no evidence of recurrence one year later. CONCLUSION: Given the local aggressive nature of PC, appropriate surgical intervention is essential in decreasing the risk of recurrence. Wide excision with clear margins has been proposed to decrease the risk of recurrence. Additionally, total-body skin examination should be done 2-3 times annually to evaluate for recurrence or metastasis.

Association of ACE1 I/D polymorphism and susceptibility to COVID-19 in Egyptian children and adolescents.

BACKGROUND: Given the sparse data on the renin-angiotensin system (RAS) and its biological effector molecules ACE1 and ACE2 in pediatric COVID-19 cases, we investigated whether the ACE1 insertion/deletion (I/D) polymorphism could be a genetic marker for susceptibility to COVID-19 in Egyptian children and adolescents. METHODS: This was a case-control study included four hundred sixty patients diagnosed with COVID-19, and 460 well-matched healthy control children and adolescents. The I/D polymorphism (rs1799752) in the ACE1 gene was genotyped by polymerase chain reaction (PCR), meanwhile the ACE serum concentrations were assessed by ELISA. RESULTS: The ACE1 D/D genotype and Deletion allele were significantly more represented in patients with COVID-19 compared to the control group (55% vs. 28%; OR = 2.4; [95% CI: 1.46-3.95]; for the DD genotype; P = 0.002) and (68% vs. 52.5%; OR: 1.93; [95% CI: 1.49-2.5] for the D allele; P = 0.032). The presence of ACE1 D/D genotype was an independent risk factor for severe COVID-19 among studied patients (adjusted OR: 2.6; [95% CI: 1.6-9.7]; P < 0.001. CONCLUSIONS: The ACE1 insertion/deletion polymorphism may confer susceptibility to SARS-CoV-2 infection in Egyptian children and adolescents. IMPACT: Recent studies suggested a crucial role of renin-angiotensin system and its biological effector molecules ACE1 and ACE2 in the pathogenesis and progression of COVID-19. To our knowledge, ours is the first study to investigate the association of ACE1 I/D polymorphism and susceptibility to COVID-19 in Caucasian children and adolescents. The presence of the ACE1 D/D genotype or ACE1 Deletion allele may confer susceptibility to SARS-CoV-2 infection and being associated with higher ACE serum levels; may constitute independent risk factors for severe COVID-19. The ACE1 I/D genotyping help design further clinical trials reconsidering RAS-pathway antagonists to achieve more efficient targeted therapies.

The Role of Pre-bone Marrow Transplantation Pulmonary Function Test in Predicting Post-transplant Noninfectious Pulmonary Complications.

Background: Pulmonary function test (PFT) is used as a tool for pre-transplant risk assessment and as a predictor of post-transplant outcomes. As there are currently few studies that discuss the role of PFT in bone marrow transplantation (BMT) patients in Saudi settings, and as the number of transplant patients with benign and malignant conditions continues to increase, this study was conducted with the aim of assessing the local practice. Methods: This retrospective cohort study included all adult patients who underwent BMT at Princess Noorah Oncology Center, King Abdulaziz Medical City, Jeddah, between 2014 and 2020. The association between established patient-related risk factors and the incidence of pulmonary complications among autologous and allogeneic groups was assessed. Results: A total of 186 patients were included (autologous = 143; allogenic = 43), of which 115 (61.8%) were male. At the pre-BMT phase, about 30% of the patients had comorbidities and 51% had received two rounds of salvage chemotherapy, while 16.1% had received radiation therapy. In the autologous group, the only PFT parameter that was a significant predictor of post-BMT pulmonary complications was forced vital capacity <80% (P = 0.012), while in the allogenic group, no parameter was significantly associated with pulmonary complications. The patient-related factors that were associated with respiratory distress in the autologous group were lung involvement (P = 0.03) and pre-transplant radiation (P = 0.044). Conclusion: The findings of this study indicated that forced vital capacity <80% was a significant factor in predicting non-infectious complications in the autologous group. Furthermore, lung involvement and pre-transplant radiation were the patient-related factors associated with pulmonary complications.

Barriers of exclusive breastfeeding among mothers attending primary health-care centers in Jazan, Saudi Arabia.

Background: Exclusive breastfeeding (EBF) describes infants who were only breastfed for 6 months. Many Saudi mothers have suboptimal breastfeeding practices. Therefore, this study aims to assess breastfeeding knowledge and determine barriers to EBF among mothers attending primary health care centers in Jazan City. Methods: A descriptive cross-sectional study was done that included all mothers attending the PHC centers. Data were collected through a self-administered questionnaire. Results: Most study participants understand breastfeeding's health benefits for babies and mothers, but most believe that synthetic milk is the best alternative for working mothers to feed their babies. A percentage of 66.7 of mothers practiced breastfeeding during the first 6 months of the child's life. EBF shows a significant relationship with knowledge and barriers. Sixty percent of mothers have never had any information about breastfeeding; the primary source was from their mothers and only 31.4% from hospital staff. Most respondents disagreed with statements of barriers to EBF, which elicits an unexpected response. Conclusions: Most participants have good knowledge concerning breastfeeding benefits for both mother and infant and disagreed on the mentioned barriers for EBF that include lack of breastmilk, deficiency of information, and working conditions.

Cotton 4-coumarate-CoA ligase 3 enhanced plant resistance to Verticillium dahliae by promoting jasmonic acid signaling-mediated vascular lignification and metabolic flux.

Lignins and their antimicrobial-related polymers cooperatively enhance plant resistance to pathogens. Several isoforms of 4-coumarate-coenzyme A ligases (4CLs) have been identified as indispensable enzymes involved in lignin and flavonoid biosynthetic pathways. However, their roles in plant-pathogen interaction are still poorly understood. This study uncovers the role of Gh4CL3 in cotton resistance to the vascular pathogen Verticillium dahliae. The cotton 4CL3-CRISPR/Cas9 mutant (CR4cl) exhibited high susceptibility to V. dahliae. This susceptibility was most probably due to the reduction in the total lignin content and the biosynthesis of several phenolic metabolites, e.g., rutin, catechin, scopoletin glucoside, and chlorogenic acid, along with jasmonic acid (JA) attenuation. These changes were coupled with a significant reduction in 4CL activity toward p-coumaric acid substrate, and it is likely that recombinant Gh4CL3 could specifically catalyze p-coumaric acid to form p-coumaroyl-coenzyme A. Thus, overexpression of Gh4CL3 (OE4CL) showed increasing 4CL activity that augmented phenolic precursors, cinnamic, p-coumaric, and sinapic acids, channeling into lignin and flavonoid biosyntheses and enhanced resistance to V. dahliae. Besides, Gh4CL3 overexpression activated JA signaling that instantly stimulated lignin deposition and metabolic flux in response to pathogen, which all established an efficient plant defense response system, and inhibited V. dahliae mycelium growth. Our results propose that Gh4CL3 acts as a positive regulator for cotton resistance against V. dahliae by promoting JA signaling-mediated enhanced cell wall rigidity and metabolic flux.

Vitamin D deficiency and vitamin D receptor FokI polymorphism as risk factors for COVID-19.

BACKGROUND: Given the sparse data on vitamin D status in pediatric COVID-19, we investigated whether vitamin D deficiency could be a risk factor for susceptibility to COVID-19 in Egyptian children and adolescents. We also investigated whether vitamin D receptor (VDR) FokI polymorphism could be a genetic marker for COVID-19 susceptibility. METHODS: One hundred and eighty patients diagnosed to have COVID-19 and 200 matched control children and adolescents were recruited. Patients were laboratory confirmed as SARS-CoV-2 positive by real-time RT-PCR. All participants were genotyped for VDR Fok1 polymorphism by RT-PCR. Vitamin D status was defined as sufficient for serum 25(OH) D at least 30 ng/mL, insufficient at 21-29 ng/mL, deficient at <20 ng/mL. RESULTS: Ninety-four patients (52%) had low vitamin D levels with 74 (41%) being deficient and 20 (11%) had vitamin D insufficiency. Vitamin D deficiency was associated with 2.6-fold increased risk for COVID-19 (OR = 2.6; [95% CI 1.96-4.9]; P = 0.002. The FokI FF genotype was significantly more represented in patients compared to control group (OR = 4.05; [95% CI: 1.95-8.55]; P < 0.001). CONCLUSIONS: Vitamin D deficiency and VDR Fok I polymorphism may constitute independent risk factors for susceptibility to COVID-19 in Egyptian children and adolescents. IMPACT: Vitamin D deficiency could be a modifiable risk factor for COVID-19 in children and adolescents because of its immune-modulatory action. To our knowledge, ours is the first such study to investigate the VDR Fok I polymorphism in Caucasian children and adolescents with COVID-19. Vitamin D deficiency and the VDR Fok I polymorphism may constitute independent risk factors for susceptibility to COVID-19 in Egyptian children and adolescents. Clinical trials should be urgently conducted to test for causality and to evaluate the efficacy of vitamin D supplementation for prophylaxis and treatment of COVID-19 taking into account the VDR polymorphisms.

Abnormal corneal nerve morphology and brain volume in patients with schizophrenia.

Neurodevelopmental and neurodegenerative pathology occur in Schizophrenia. This study compared the utility of corneal confocal microscopy (CCM), an ophthalmic imaging technique with MRI brain volumetry in quantifying neuronal pathology and its relationship to cognitive dysfunction and symptom severity in schizophrenia. Thirty-six subjects with schizophrenia and 26 controls underwent assessment of cognitive function, symptom severity, CCM and MRI brain volumetry. Subjects with schizophrenia had lower cognitive function (P ≤ 0.01), corneal nerve fiber density (CNFD), length (CNFL), branch density (CNBD), CNBD:CNFD ratio (P < 0.0001) and cingulate gyrus volume (P < 0.05) but comparable volume of whole brain (P = 0.61), cortical gray matter (P = 0.99), ventricle (P = 0.47), hippocampus (P = 0.10) and amygdala (P = 0.68). Corneal nerve measures and cingulate gyrus volume showed no association with symptom severity (P = 0.35-0.86 and P = 0.50) or cognitive function (P = 0.35-0.86 and P = 0.49). Corneal nerve measures were not associated with metabolic syndrome (P = 0.61-0.64) or diabetes (P = 0.057-0.54). The area under the ROC curve distinguishing subjects with schizophrenia from controls was 88% for CNFL, 84% for CNBD and CNBD:CNFD ratio, 79% for CNFD and 73% for the cingulate gyrus volume. This study has identified a reduction in corneal nerve fibers and cingulate gyrus volume in schizophrenia, but no association with symptom severity or cognitive dysfunction. Corneal nerve loss identified using CCM may act as a rapid non-invasive surrogate marker of neurodegeneration in patients with schizophrenia.

Occupational ocular health problems among marble workers at Shaq El Tho'ban industrial area in Egypt.

Eye health of the working population is an essential condition for productivity. Marble industry is processed at large scale at Shaq El Tho'ban area where much dust, crushed pieces of stone, and fluctuating temperatures are endangering employees' health generally and eye health specifically. The objectives of this study were assessing the prevalence of the most common ocular health problems associated with marble industry and investigating the impact of the working environment and occupational risk factors on the oculo-visual status of marble workers. A cross-sectional study was conducted among 250 workers, working at Shaq El Tho'ban area in Egypt during the period from August 2020 to September 2021, using a semi-structured questionnaire and eye examination comprised of full ocular history, visual acuity testing (unaided/aided), slit lamp examination, ophthalmoscopy, and Schirmer's type I and tear break up time tests. The current study showed that gritty sensation (65.2%) and eye dryness (51.2%) were the commonest symptoms complained. By examination, conjunctival hyperemia (59.6%) was the most prevalent finding. By performing dry eye tests, dry eye was diagnosed in 60.4% and 51.2% of workers by Schirmer's test and tear break up time test respectively. The study's results indicated that age, working category, smoking, and diabetes had significant impact on development of ocular symptoms, while working duration, diabetes, smoking, ocular symptoms, and ocular foreign body had significant impact on development of dry eye disease. Implementation of engineering control measures, proper designing, and supply of eye PPE together with adequate health education to all workers about occupational health risks and preventive measures are recommended.

Prevalence and predictors of occupational asthma among workers in detergent and cleaning products industry and its impact on quality of life in El Asher Men Ramadan, Egypt.

Cleaning products are mixtures of many chemical ingredients that are known to contain sensitizers, disinfectants, and fragrances, as well as strong airway irritants which associated with lower respiratory tract and asthma symptoms. The aim of this study is to assess the prevalence and possible risk factors of occupational asthma and its effect on quality of life among workers in detergent and cleaning products industries in El Asher men Ramadan city. This cross-sectional study was conducted on 780 workers. All participants were personally interviewed at their workplaces and were subjected to a questionnaire regarding sociodemographic, work characteristics and asthma symptoms, clinical examination, chest X-ray, spirometer, and bronchodilator test. The prevalence of occupational asthma among the studied workers was 35.4%. Multivariate logistic regression analysis revealed that female gender [odds ratio 1.397; 95% CI 1.09-1.96], manually working participants [odds ratio 3.067; 95% CI 1.72-5.46], and history of atopy [odds ratio 1.596; 95% CI 1.09-2.33] were risk factors for development of occupational asthma. The total mean score of asthma-specific quality of life was significantly lower in asthmatic (5.10 ± 0.49) than non-asthmatic workers (5.89 ± 0.46) (P < 0.01) indicating impairment of quality of life among asthmatic group. Workers in detergent and cleaning products industry are at higher risk for developing occupational asthma that adversely affects their general health and quality of life.

Occupational dermatoses: knowledge, attitudes and perceptions among motor vehicle repair workers.

Objectives. Motor vehicle repair workers are a vulnerable group for developing occupational dermatoses. They are exposed to a wide range of chemical, physical and mechanical hazards. This study aimed to assess the prevalence of occupational dermatoses among motor vehicle repair workers and their risk factors, and to evaluate the effect of a health educational program. Methods. The study was conducted among 106 motor vehicle repair workers. All participants were personally interviewed at their workshops and were subjected to the Nordic occupational skin questionnaire, dermal exposure knowledge, attitudes and perceptions questionnaire, dermatological examination and health educational program. Then, evaluation of the effects of health the program was done after 2 months. Results. Exclusively occupational dermatoses (18.9%) were followed by work-related dermatoses (17.9%). Chronic contact dermatitis was the most frequent exclusively occupational dermatoses (12.26%), followed by tar/oil acneform rash (3.77%) and mechanical injury (3.77%). Xerosis (6.6%) and hyperpigmentation (4.71%) were the most frequent work-related dermatoses. Lack of use of personal protective equipment, older age, longer duration of work, exposure to chemical hazards and car mechanics were the independent risk factors. Conclusions. A significant improvement occurred in the participants' knowledge about dermal exposure, behavioral action for prevention and overall belief (pre/post intervention) (p < 0.01).

Early infection in post-autologous hematopoietic stem cell transplant patients: Princess Noorah Oncology Center experience.

OBJECTIVES: To assess local epidemiology and risk factors for bacterial, fungal, and viral infections among the autologous bone marrow transplant population. METHODS: This study is a retrospective correlational cohort design comprising 150 adult patients who underwent autologous transplants at Princess Noorah Oncology Center, Jeddah, Saudi Arabia between 2014 and 2020. RESULTS: The study findings indicate that bacterial infection prevalence differed significantly across the different disease status pre-salvage as patients with the relapsed disease were more likely to have bacterial infections. The median of engraftment days differed significantly between those who had a bacterial infection and those who did not. Interestingly, previous pneumonia infection had a positive relationship with the number of hospital stays. CONCLUSIONS: Bacterial infections are the dominant type of infection among the autologous patient population. The research reflects authentic practice and reports unique characteristics of autologous transplant patients in terms of the prevalence and types of infection these patients experience.

Advantages of Small Incision Lenticule Extraction (SMILE) for Mass Eye and Ear Special Issue.

This review summarizes the advantages of Small-incision lenticule extraction (SMILE), including improved patient intraoperative experience, improved postoperative ocular surface, low incidence of regression, low re-treatment rates, and advantageous biomechanical corneal stability. Visual and refractive outcomes are similar to those achieved with LASIK, notably in large population studies. Since the inception of SMILE almost 10 years ago, the procedure has been rapidly growing in popularity. With the implementation of the novel SMILE technology in their practice, refractive surgeons generate excitement and potential for expanding the refractive market. Other parts of the world, including Asia, Europe, and Russia, SMILE has become the most popular refractive procedure performed. It is speculated that as SMILE continues to grow in popularity in the US since FDA approval in 2016 and more refractive surgeons implement this technology into their practice, it will drive an increase in the refractive market similar to what is seen in other countries.

Genetic Modification of mfsT Gene Stimulating the Putative Penicillin Production in Monascus ruber M7 and Exhibiting the Sensitivity towards Precursor Amino Acids of Penicillin Pathway.

: The biosynthesis of penicillin G (PG) is compartmentalized, which forces penicillin and its intermediates to cross the membrane barriers. Although many aspects around the penicillin intermediates traffic system remain unclosed, the transmembrane transporter protein involvement has been only predicted. In the present work, detection of PG and isopenicillin N (IPN) in Monascus ruber M7 was performed and functions of mfst gene as a transporter were investigated by the combination of gene deletion (Δmfst) complementation (ΔmfsT::mfsT) and overexpression (M7::PtrpC-mfsT). While, the feeding of PG pathway precursor side chain and amino acids, i.e., phenylacetic acid, D-valine, and L-cysteine was performed for the interpretation of mfsT gene role as an intermediate transporter. The results showed that, the feeding of phenylacetic acid, D-valine, and L-cysteine possessed a significant effect on morphologies, secondary metabolites (SMs) production of all above-mentioned strains including M. ruber M7. The results of UPLC-MS/MS revealed that, ΔmfsT interrupt the penicillin G (PG) production in M. ruber M7 by blocking the IPN transportation, while PG and IPN produced by the ΔmfsT::mfsT have been recovered the similar levels to those of M. ruber M7. Conclusively, these findings suggest that the M. ruber M7 is, not only a PG producer, but also, indicate that the mfsT gene is supposed to play a key role in IPN intermediate compound transportation during the PG production in M. ruber M7.
