Knowledge, awareness and attitude towards breast cancer: Risk factors, signs and screening among Health and Allied students: A prospective study.

Introduction: Breast cancer (BC) is the second most common cancer in Saudi women. Therefore, understanding BC and its related risk factors, symptoms, and screening is critical for early detection and intervention. The current study was meant to explore the knowledge, awareness, and attitude (KAA) gap in BC: risk factors, symptoms, and screening. Material and Methods: This cross-sectional investigation was carried out with Health Professions Students (HPS) using a predesigned and validated study questionnaire to examine HPS knowledge and attitudes concerning BC and associated risk factors, symptoms, and screening. Results: A total of 277 female students responded to the survey. The frequency of correct answers for the BC knowledge questions varied from the lowest of 27.8% to the highest of 88.8%, with only 5 out of 15 questions (33.3%) answered correctly by more than 60% of the participants, displaying poor knowledge and awareness of BC. A majority (>60%) of the participants identified only 7 of the 18 risk factors of BC correctly, whereas 11 of the 13 early warning signs of BC were identified correctly by the majority (>60%) of the participants. Among the participants, only 26.4% were aware of the breast cancer screening center, but 94.6% of them agreed that early detection of breast cancer is important and 82.7% agreed to participate in the screening program if offered. Conclusion: Participants' knowledge and awareness of BC were found to be relatively low; however, their attitudes towards BC screening were positive. As a result, it is critical to develop effective education programs, curricular activities, and awareness campaigns to address the lack of awareness of BC and to have an appropriate response to screening to reduce disease burden.

TNIK Inhibition Sensitizes TNIK-Overexpressing Lung Squamous Cell Carcinoma to Radiotherapy.

Most patients with lung squamous cell carcinoma (LSCC) undergo chemotherapy, radiotherapy, and adjuvant immunotherapy for locally advanced disease. The efficacy of these treatments is still limited because of dose-limiting toxicity or locoregional recurrence. New combination approaches and targets such as actionable oncogenic drivers are needed to advance treatment options for patients with LSCC. Moreover, other options for chemotherapy-ineligible patients are limited. As such, there is a critical need for the development of selective and potent chemoradiosensitizers for locally advanced LSCC. In this study, we investigated inhibiting TRAF2- and NCK-interacting protein kinase (TNIK), which is amplified in 40% of patients with LSCC, as a strategy to sensitize LSCC tumors to chemotherapy and radiotherapy. Employing a range of human LSCC cell lines and the TNIK inhibitor NCB-0846, we investigated the potential of TNIK as a chemo- and radiosensitizing target with in vitro and in vivo preclinical models. The combination of NCB-0846 with cisplatin or etoposide was at best additive. Interestingly, pre-treating LSCC cells with NCB-0846 prior to ionizing radiation (IR) potentiated the cytotoxicity of IR in a TNIK-specific fashion. Characterization of the radiosensitization mechanism suggested that TNIK inhibition may impair the DNA damage response and promote mitotic catastrophe in irradiated cells. In a subcutaneous xenograft in vivo model, pretreatment with NCB-0846 significantly enhanced the efficacy of IR and caused elevated necrosis in TNIKhigh LK2 tumors but not TNIKlow KNS62 tumors. Overall, these results indicate that TNIK inhibition may be a promising strategy to increase the efficacy of radiotherapy in patients with LSCC with high TNIK expression.

Prevalence, Etiology, Risk Factors, and Complications of Facial Nerve Palsy at King Abdulaziz Medical City: A Multicenter Study.

BACKGROUND: Facial nerve palsy is a condition of nerve damage that results in impaired facial movement on one or both sides of the face. OBJECTIVES: This multicenter study aimed to determine the prevalence of facial nerve palsy and evaluate the association between its risk factors and complications to identify its etiology among patients admitted to King Abdulaziz Medical City in Jeddah and Riyadh, Saudi Arabia, between 2016 and 2023. METHODS: A retrospective cross-sectional study was conducted to obtain data from medical records using the best care system for patients with facial nerve palsy. Data were analyzed using IBM SPSS Statistics for Windows, Version 20.0 (Released 2011; IBM Corp., Armonk, New York, United States), Chi-square test, t-test, and ANOVA. The level of statistical significance was set at p<0.05. RESULTS:  The study involved 123 patients, with 0.0164% prevalence. Bell's palsy was the most common etiology, accounting for 81.8% of cases, followed by head injuries, dental trauma, otitis media, stroke, and head and neck tumors. Obesity was the most significant risk factor, followed by upper respiratory problems. Hypertension and diabetes exert similar effects. Facial asymmetry, ophthalmic complications, and eye twitching were the most common complaints followed by speech difficulties, psychological and social effects, mouth twitching, and synkinesis. CONCLUSION:  Facial nerve palsy is common in this region. We recommend health education sessions to increase public awareness and provide preventive strategies to reduce the complications of facial nerve damage. We recommend further research on the association between the risk factors and complications of facial nerve palsy.

Non-mitotic proliferation of malignant cancer cells revealed through live-cell imaging of primary and cell-line cultures.

INTRODUCTION: Anti-mitosis has been a key strategy of anti-cancer therapies, targeting at a fundamental property of cancer cells, their non-controllable proliferation due to overactive mitotic divisions. For improved anti-cancer therapies, it is important to find out whether cancer cells can proliferate independent of mitosis and become resistant to anti-mitotic agents. RESULTS: In this study, live-cell imaging was applied to both primary-cultures of tumor cells, and immortalized cancer cell lines, to detect aberrant proliferations. Cells isolated from various malignant tumors, such as Grade-III hemangiopericytoma, atypical meningioma, and metastatic brain tumor exhibit distinct cellular behaviors, including amoeboid sequestration, tailing, tunneling, nucleic DNA leakage, as well as prokaryote-like division such as binary fission and budding-shedding, which are collectively referred to and reported as 'non-mitotic proliferation' in this study. In contrast, benign tumors including Grade-I hemangiopericytoma and meningioma were not obvious in such behaviors. Moreover, when cultured in medium free of any anti-cancer drugs, cells from a recurrent Grade-III hemangiopericytoma that had been subjected to pre-operation adjuvant chemotherapy gradually shifted from non-mitotic proliferation to abnormal mitosis in the form of daughter number variation (DNV) and endomitosis, and eventually regular mitosis. Similarly, when treated with the anti-cancer drugs Epirubicin or Cisplatin, the cancer cell lines HeLa and A549 showed a shift from regular mitosis to abnormal mitosis, and further to non-mitosis as the dominant mode of proliferation with increasing drug concentrations. Upon removal of the drugs, the cells reversed back to regular mitosis with only minor occurrences of abnormal mitosis, accompanied by increased expression of the stem cell markers ALDH1, Sox, Oct4 and Nanog. CONCLUSIONS: The present study revealed that various types of malignant, but not benign, cancer cells exhibited cellular behaviors indicative of non-mitotic proliferation such as binary fission, which was typical of prokaryotic cell division, suggesting cell level atavism. Moreover, reversible transitions through the three modes of proliferation, i.e., mitosis, abnormal mitosis and non-mitosis, were observed when anticancer drug concentrations were grossly increased inducing non-mitosis or decreased favoring mitosis. Potential clinical significance of non-mitotic proliferation in cancer drug resistance and recurrence, and its relationship with cancer stem cells are worthy of further studies.

Disease characteristics, pathogenesis, and treatment controversies of axial psoriatic arthritis.

Axial psoriatic arthritis (axPsA) has considerable overlap with axial spondyloarthritis (axSpA) but has some unique features that sometimes preclude classification into axSpA. It has some clinical and radiographic differences compared to axSpA. Imaging typically shows asymmetric syndesmophytes, mainly in the cervical spine, with less frequent sacroiliitis. It more commonly presents later in life and is associated with less severe inflammatory back pain than axSpA. The interleukin (IL) IL-23/IL-17 axis is central to the pathogenesis of both diseases. However, the response to therapies targeting these cytokines has been different. IL-23 inhibitors are ineffective in axSpA but may be effective in psoriatic arthritis (PsA). Recent post hoc analyses of clinical trial data with IL-23 inhibitors in PsA have raised the possibility of their efficacy in axPsA and need evaluation in future clinical trials. Moreover, there is a need for classification criteria for axPsA and better tools to assess therapeutic response.

The effectiveness of kangaroo mother care in lowering postpartum depression in mothers of preterm and low birth weight babies: a systematic review and meta-analysis.

Background: Kangaroo mother care (KMC) intervention involves skin-to-skin contact between mother and infant. Some studies have shown a decrease in postpartum depression (PPD) in mothers of preterm and low birth weight (LBW) infants. However, the literature is scattered and of variable quality. Aims: To conduct a systematic review of available literature and provide a comprehensive picture of the effect of KMC on PPD among mothers of preterm and LBW infants. Methods: The study was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Guidelines. After PROSPERO registration, a systematic search was conducted using PubMed, Cochrane Central Library, and Google Scholar from the inception of the databases till 14 June 2021. Of the 2944 studies assessed for titles and abstracts, nine studies with 2042 participants were included in the review. Included articles targeted mothers with LBW (<2500 g) or preterm infants (<37 weeks), used an authentic PPD tool, and had standard care or an incubator as the control group. Studies not published in English and in which mothers had a previous psychiatric illness were excluded. The risk of bias was assessed using the Cochrane Risk of Bias Tool for randomized control trials and the Newcastle-Ottawa Scale for observational studies. All the results were converted to standard mean deviation and pooled together using a random-effects model with a 95% CI. A P-value of less than 0.05 is considered significant. Results: KMC Intervention was significantly associated with a lower depression score than control groups. The reduction in depression in the intervention (KMC) group was moderate: SMD=-0.38 (-0.68 to -0.08; 95% CI; I 2=86%; P=0.013). No significant difference was found between the PPD scores of both groups using the Edinburgh Postpartum Depression Scale score. Conclusions: The authors conclude that the negative effects of LBW and preterm birth experience on maternal mental health can be avoided to a moderate degree by KMC. Due to a lack of methodological uniformity, different scales for outcome measurement, and discrepancies in intervention features, significantly high heterogeneity was detected. The authors need further larger-scale studies with a uniform study design to better predict the efficacy of KMC better.

HLA-B*27 and Ankylosing Spondylitis: 50 Years of Insights and Discoveries.

PURPOSE OF REVIEW: To commemorate the 50th anniversary of the groundbreaking discovery of a remarkably strong association between HLA-B*27 and ankylosing spondylitis (AS). RECENT FINDINGS: In addition to HLA-B*27, more than 116 other recognized genetic risk variants have been identified, while epigenetic factors largely remain unexplored in this context. Among patients with AS who carry the HLA-B*27 gene, clonally expanded CD8 + T cells can be found in their bloodstream and within inflamed tissues. Moreover, the α and ß chain motifs of these T-cell receptors demonstrate a distinct affinity for certain self- and microbial-derived peptides, leading to an autoimmune response that ultimately results in the onset of the disease. These distinctive peptide-binding and presentation characteristics are a hallmark of the disease-associated HLA-B*27:05 subtype but are absent in HLA-B*27:09, a subtype not associated with the disease, differing by only a single amino acid. This discovery represents a significant advancement in unraveling the 50-year-old puzzle of how HLA-B*27 contributes to the development of AS. These findings will significantly accelerate the process of identifying peptides, both self- and microbial-derived, that instigate autoimmunity. This, in return, will pave the way for the development of more accurate and effective targeted treatments. Moreover, the discovery of improved biomarkers, in conjunction with the emerging technology of electric field molecular fingerprinting, has the potential to greatly bolster early diagnosis capabilities. A very recently published groundbreak paper underscores the remarkable effectiveness of targeting and eliminating disease-causing T cells in a HLA-B*27 patients with AS. This pivotal advancement not only signifies a paradigm shift but also bolsters the potential for preventing the disease in individuals carrying high-risk genetic variants.

General Public Knowledge, Attitude, and Practice Regarding the Impact of Air Pollution and Cardiopulmonary Diseases in Jeddah, Saudi Arabia.

Introduction Air pollution is a critical public health issue associated with various respiratory and cardiovascular diseases. The lungs and heart are the organs most affected by air pollution, and damage to these organs is strongly associated with inhaled particulate matter produced by burning fossil fuels. Household and ambient air pollution have been closely linked to lower respiratory infections, with ambient air pollution alone estimated to be responsible for millions of deaths globally each year. Therefore, this study aimed to assess the general public knowledge attitude and practice regarding air pollution and cardiopulmonary morbidity in Jeddah, Saudi Arabia. Methods The study was conducted in Saudi Arabia using a self-administered questionnaire distributed through popular social media apps. A snowball sampling technique was used, including only Saudi citizens aged 18 or older. The questionnaire consisted of 30 questions derived from a comprehensive literature review on the subject matter. Questions were validated through face validity, pilot testing, and Cronbach's alpha reliability measurement. The questionnaire included questions on demographic data, knowledge of air pollution, the relationship between air pollution and cardiopulmonary diseases, and attitudes and practices toward lowering exposure to air pollution. Results The study included 649 participants, with a mean age of 32.11 ± 13.47 years, and over half were females (54.7%). Most participants were aware of outdoor and indoor air pollution, but only a tiny percentage recognized cooking as a primary indoor source of pollution. However, the majority believed that indoor pollution could contribute to outdoor pollution. Participants associated air pollution with cardiopulmonary diseases, mainly secondhand tobacco smoke and outdoor air pollution caused by factories and industrial facilities. Knowledge and practice levels varied, with older individuals, females, and those in non-health-related occupations having higher levels of knowledge. Positive attitudes, particularly believing that moving to a less polluted area improves health, were associated with better knowledge. Females exhibited better air pollution-related practices, and there was a positive correlation between knowledge and practice scores. Conclusion The study highlighted the need for targeted public health campaigns to improve awareness and promote healthier practices, particularly among young adults, to mitigate the potential health impacts of air pollution, especially cardiopulmonary health.

Neurological Manifestations in Hospitalized Geriatric Patients With COVID-19 at King Abdulaziz Medical City in Jeddah, Western Region, Saudi Arabia From 2020 to 2021: A Cross-Sectional Study.

Introduction COVID-19 involvement in the nervous system has been reported in many cases. Viral neuroinvasion has multiple routes of entry. Neurological manifestations of COVID-19 can be divided into ones of the central nervous system (CNS), such as headache, dizziness, altered mental status, ataxia, and seizure, and of the peripheral nervous system (PNS), including ageusia, anosmia, acute illness demyelinating polyneuropathy, and neuralgia. Aim and objectives This study aims to observe and report the neurological manifestations in geriatric patients who were diagnosed with COVID-19 at KAMC-J and report the duration of admission to the in-patient and ICU wards. Methods This was a cross-sectional study conducted on admitted geriatric patients with PCR-confirmed COVID-19 from April 1, 2020 to June 30, 2021 at KAMC-J. Using Raosoft®, the sample size was estimated with a CI of 95% and a 36.4% prevalence of neurological symptoms in COVID-19 patients to be 289. Convenience sampling was used, and the data were collected from BESTCare EMRs. IBM SPSS Statistics for Windows, Version 20 (Released 2011) was used for descriptive and inferential statistical analysis. Results In this study, a total of 290 patients' data were collected, 161 (55.5%) of which were males. In addition, the median age was 71 (Q1-Q3: 65-78) years; furthermore, the median body mass index (BMI) was 30(Q1-Q3: 25-34) kg/m2. In descending order, the most prevalent comorbidities were hypertension (HTN) (70.3%), diabetes mellitus (DM) (68.6%), cardiac disease (42.1%), chronic kidney disease (26.6%), neurological disease (23.6%), cancer malignancy (13.1%), and finally chronic respiratory disease (11.4%). Regarding typical COVID-19 manifestations, 181 patients claimed to have experienced cough (62.4%), dyspnea by 164 (56.7%), fever by 154 (53.5%), fatigue by 93 (32.3%), a reading of anoxia by 68 (23.4%), abdominal pain by 58 (20.0%), diarrhea by 56 (19.4%), and finally throat pain by 19 (6.6%). Manifestations and pathologies of the CNS included headache (25.4%), dizziness (21.5%), impaired consciousness (17.2%), delirium (6.6%), ischemic stroke (4.1%), focal cranial nerve dysfunction (2.8%), seizure (2.8%), intracerebral hemorrhage (ICH) (0.3%), and ataxia (0.3%). Moreover, pathologies of the PNS manifested as taste impairment in 46 patients (15.9%), smell impairment in 33 (11.4%), nerve pain in 7 (24%), visual impairment in 5 (1.7%), Bell's palsy in 2 (0.7%), and Guillain-Barre syndrome in 1 (0.3%). Moreover, the majority of patients who developed an ischemic stroke or ICH, or required admission to the ICU had either DM or HTN. In addition, 17 (25.4%) of the 67 patients admitted to the ICU developed impaired consciousness. All-cause mortality in our study was 31 (10.71%) cases. Conclusion Neurological manifestations of COVID-19 are common and can result in serious complications if not detected and managed early, especially in the elderly. These complications are mostly seen in severely ill patients and may be the only symptoms in COVID-19 patients. In addition, patients' clinical conditions could deteriorate rapidly and result in significant morbidity and mortality. Therefore, a high index of suspicion is required among healthcare providers when dealing with such cases. Moreover, we recommend systematically collecting data on the short- and long-term neurological complications of COVID-19 globally and documenting the functional long-term outcomes after these complications.

Efficacy of varicocelectomy on semen parameters and conception rates.

Objective: Varicocele, the dilation of the pampiniform plexus of the spermatic cord. It is discovered incidentally in most patients. Symptoms vary, but its impact is especially experienced in the field of fertility and reflected in semen parameters. Varicocelectomy is a surgical approach to correct the varicocele, however, reports are conflicting regarding its success. Our aim was to evaluate the efficacy of varicocelectomy on semen parameters and conception rates in patients who underwent surgery and its association with comorbidities such as diabetes, hypertension, and obesity. Materials and Methods: This cross-sectional study included the complete medical records of 86 patients. Data collection form included the patient's age, body mass index (BMI), chronic diseases, smoking, surgical history, medication usage, and the reason for performing surgery. Presurgical and postsurgical semen parameters were evaluated 3 months before surgery and an average of 6 months postoperatively. Data were analyzed with SPSS, Chi-square test, and independent and paired t-test. Results: No significant difference was found between primary and secondary infertility regarding semen analysis, postoperative semen analysis indicated an improvement in semen motility at 180 min with no effect on other parameters. Using spontaneous intercourse or in vitro fertilization (IVF) after varicocelectomy was significantly associated with increasing conception rates irrespective of the type of infertility. Diabetes, hypertension, BMI, and smoking did not appear to affect semen parameters. Conclusion: Patients who underwent varicocelectomy had improved sperm motility at 180 min and subsequently had a higher chance of successful conception either through spontaneous intercourse or IVF. Further studies are needed to understand the relationship between conception and sperm motility. Semen parameters were not affected if the patient had comorbidities such as diabetes and hypertension. Furthermore, smoking and BMI did not appear to affect the conception rate.

Late Presentation of Acute Coronary Syndrome Complicated by Ventricular Septal Rupture.

Acquired ventricular septal rupture (VSR) is a rare but potentially fatal complication of late-presenting myocardial infarction (MI). In the era of revascularization and reperfusion therapy, the incidence of VSR has significantly decreased. Ruptures occur predominantly in patients with late-presenting ST elevation MI. Patients may present with a wide variety of symptoms ranging from chest pain and mild hemodynamic instability to profound cardiogenic shock. Inotropes, vasopressors, and mechanical support with intra-aortic balloon pumps and extracorporeal membrane oxygenation can be used to bridge patients to surgery. Despite treatment with ventricular septal repair, postsurgical mortality remains high. There is a wide variety of complications that can occur in the postoperative period. A multidisciplinary approach is vital in these patients who develop VSR. Improving awareness among healthcare professionals regarding the symptoms of acute coronary syndrome can hopefully help prevent delayed presentation of patients to healthcare facilities.

Compliance With the World Health Organization Surgical Safety Checklist at a Tertiary Care Hospital: A Closed Loop Audit Study.

BACKGROUND AND OBJECTIVE: The WHO launched the "Safe Surgery Saves Lives" campaign in 2008 to improve patient safety during surgery. The campaign includes the use of the WHO Surgical Safety Checklist, which has been proven effective in reducing complications and mortality rates in several studies. This article discusses a clinical audit at a tertiary healthcare facility that assesses compliance with all three components of the checklist to minimize errors and improve safety standards. MATERIALS AND METHODS: This prospective, observational, closed-loop clinical audit study was conducted at Hayatabad Medical Complex, a tertiary care public sector hospital located in Peshawar, Pakistan. The audit aimed to assess compliance with the WHO Surgical Safety Checklist. The first phase of the audit cycle commenced on October 5, 2022, and involved collecting data from 91 surgical cases in randomly selected operating rooms. Following the completion of the first phase on December 13, 2022, an educational intervention was then conducted on December 15 to underscore the significance of adhering to the checklist, and the second phase of data collection began the following day, ending on February 22, 2023. The results were analyzed using SPSS Statistics version 27.0. RESULTS: The first phase of the audit showed that there was poor compliance with the latter two parts of the checklist. Certain components of the WHO Surgical Safety Checklist were well-complied with, including patient identity confirmation (95.6%), obtaining informed consent (94.5%), and counting of sponges and instruments (95.6%), while the lowest compliance rates were in recording allergies (26.3%), assessing blood loss risk (15.3%), introducing team members (62.6%), and inquiring about patient recovery concerns (64.8%, 34%, and 20.8% for surgeons, anesthetists, and nurses, respectively). In the second phase, after an educational intervention, compliance with the checklist improved significantly, particularly for those components with low compliance rates in the first phase, marking recording allergies (89.0%), introducing team members 91.2%), and inquiring about patient recovery concerns (79.1%, 73.6%, and 70.3% for surgeons, anesthetists, and nurses, respectively). CONCLUSION: The study showed that education is a critical factor in improving compliance with the WHO Surgical Safety Checklist. The study suggests that overcoming the obstacles to implementing the checklist requires a collaborative environment and effective instruction. It emphasizes the importance of adhering to the checklist in all surgical settings.

A single-center experience of post-transplant atypical hemolytic uremic syndrome.

PURPOSE: Atypical hemolytic uremic syndrome (aHUS) is a genetic-based thrombotic microangiopathy (TMA) that is mediated by the activation of the alternative complement pathway. Heterozygous deletion in CFHR3-CFHR1 occurs in 30% of the general population and has not been classically linked to aHUS. Post-transplant aHUS has been associated with a high rate of graft loss. Herein, we report our case series of patients who developed aHUS after solid-organ transplantation. MATERIALS AND METHODS: Five consecutive cases of post-transplant aHUS were identified at our center. Genetic testing was performed in all but one. RESULTS: One patient had a presumed TMA diagnosis before transplant. One heart and 4 kidney (KTx) transplant recipients were diagnosed with aHUS based on the clinical picture of TMA, acute kidney injury, and normal ADAMTS13 activity. Genetic mutation testing revealed heterozygous deletion in CFHR3-CFHR1 in 2 patients and a heterozygous complement factor I (CFI) variant of uncertain clinical significance (VUCS) (Ile416Leu) in a third. Four patients were on tacrolimus, 1 had anti-HLA-A68 donor-specific antibody (DSA), and another had borderline acute cellular rejection at the time of aHUS diagnosis. Four responded to eculizumab, and 1 out of 2 patients came off renal replacement therapy. One KTx recipient died from severe bowel necrosis in the setting of early post-transplant aHUS. CONCLUSION: Calcineurin inhibitors, rejection, DSA, infections, surgery, and ischemia-reperfusion injury are common triggers that could unmask aHUS in solid-organ transplant recipients. Heterozygous deletion in CFHR3-CFHR1 and CFI VUCS may be important susceptibility factors acting as the first hit for alternative complement pathway dysregulation.

The impact of epidural analgesia for acute pancreatitis on maternal and fetal outcome: a cohort study.

It is anticipated that between 1 in 10, 000 and 1 in 30, 000 pregnancies will be affected by acute pancreatitis (AP). The authors wanted to evaluate the impact of epidural analgesia on maternal and fetal outcomes and its effectiveness in the pain treatment of obstetric patients with AP. Methodology: The period for this cohort research was from January 2022 to September 2022. Fifty pregnant women with AP symptoms were enrolled in the study. Conservative medical management was done using intravenous (i.v.) analgesics, including fentanyl and tramadol. Fentanyl was infused i.v. at a rate of 1 µg/kg every hour, while tramadol was bolused i.v. at 100 mg/kg every 8 h. Boluses of 10-15 ml of 0.1% ropivacaine were injected into the L1-L2 interspace at 2-3-h intervals to provide high lumbar epidural analgesia. Results: In this study, 10 patients were given an i.v. infusion of fentanyl, and 20 patients were given tramadol boluses. Epidural analgesia showed the most promising results decreasing the visual analog scale score from 9 to 2 in half of the patients. Most fetal complications were noticed in the tramadol group, including prematurity, respiratory distress, and babies requiring noninvasive ventilation. Conclusion: Patients with AP during pregnancy may benefit from a new technique for simultaneous analgesia during labor and cesarean section administered via a single catheter. When AP is detected and treated during pregnancy, the mother and child benefit from pain control and recovery.

Prevalence of Etiological Factors in Adult Patients With Epilepsy in a Tertiary Care Hospital in the Western Region of Saudi Arabia: A Cross-Sectional Study.

Background Epilepsy is a chronic neurologic condition with different risk factors and genetic predispositions. It is characterized by the occurrence of an epileptic seizure. To our knowledge, most studies have focused on revealing epilepsy prevalence in Saudi Arabia, but the etiological prevalence is still not well-studied in the region. Thus, this research aims to raise awareness and provide more insights into the etiological prevalence of this disorder. Methodology A cross-sectional study was performed among 431 adult patients diagnosed with epilepsy in the Neurology Department at King Abdulaziz Medical City in Jeddah, Saudi Arabia. Patients' data were retrospectively collected from electronic medical files covering the period between May 2016 and April 2021. Epilepsy etiologies were classified as suggested by the International League Against Epilepsy 2017. Results The most commonly identified seizures were generalized (25.3%) and focal (8.9%). However, 66.1% of seizure types were unidentifiable. The most common etiology was structural (42.9%), followed by genetic (7.2%), with strokes (24.3%) and tumors (23.8%) being the most prevalent structural etiologies. However, 47.6% of the patients were classified under unknown etiology. Conclusions This study suggested that epilepsy diagnosed as generalized was by far the most common seizure type in our cohort. Structural etiology was evident in most patients, with stroke being the highest presented etiology.

Practising refraction in ophthalmology: instructive or outdated? A prospective study and literature review.

CLINICAL RELEVANCE: Many ophthalmologists preform clinical refactions, although little is known of the perceptions and practise of refraction by ophthalmologists and key barriers preventing this aspect of ophthalmic practice. BACKGROUND: Although there are numerous studies on visual acuity in ophthalmology, there is no study to date on the practice of refraction by ophthalmologists. This study evaluates the practice patterns of ophthalmologists in current practice. It specifically addresses perceptions of ophthalmologists about (a) the importance of refraction in clinical practice, and (b) barriers to performing refraction. The methodology and frequency of performing refraction by ophthalmologists is also assessed. METHODS: This cross-sectional study was conducted at the Annual Scientific Congress of the Royal Australian and New Zealand College of ophthalmologists in 2017, held in Perth, Australia. All attending ophthalmologists and ophthalmology trainees were invited to participate. Participants completed a 17-variable questionnaire on the perceptions of practitioners about refraction and their practice of it. Data were analysed using Microsoft Excel and IBM SPSS Version 24. RESULTS: At this Congress, 213 attendees completed the survey, with most being consultant general ophthalmologists (85%). Twenty-six percent of participants either 'really loved' or 'liked' refracting patients. Those who reported feeling competent with refraction were more likely to perform it themselves (p = 0.001). Individuals most commonly reported taking 3-5 minutes to refract a patient (38%). Participants under the age of 65, and participants practising paediatric ophthalmology, were more likely to perform a refraction. CONCLUSIONS: The literature indicates that this is the first study to describe the practice patterns of refraction by ophthalmologists. Although ophthalmologists found refraction important, the majority preferred patients to be refracted by others. Key barriers to ophthalmologists performing refraction included the time required to perform the refraction, a busy clinic, and the availability of alternative providers.

Assessment of Pre-existing Type 2 Diabetes Mellitus Prevalence and Risk Factors Among Colorectal Cancer Patients in King Abdulaziz Medical City, Jeddah.

BACKGROUND: Diabetes mellitus (DM) and cancer are recognized as non-communicable chronic disorders which are among the top ten causes of death globally. In Saudi Arabia, the prevalence of type 2 DM (T2DM) and colorectal cancer (CRC) is alarmingly high. Both T2DM and CRC share common risk factors. In this study, we aim to assess the prevalence of pre-existing T2DM among CRC Saudi patients. METHODS: In this cross-sectional study, data were collected from the medical records of 275 Saudi adult patients with CRC from 2009 to 2018 at King Abdulaziz Medical City, Jeddah (KAMC-J). RESULTS: Participants had a mean age of 57.0 years, standard deviation (SD) of 13.0, and were mostly males (60.00%) and Saudi (100.0%). Participants had a mean BMI of 26.42 (7.35) kg/m2. The prevalence of pre-existing T2DM in this study was 40.80%. 15.8% of participants were overweight and obese (BMI>30), respectively. The average age of diabetics and non-diabetics was 63.6 (10.64) and 52.73 (12.43), respectively. Diabetic patients are significantly older than non-diabetic patients (p<0.001). The average BMI for diabetics was 26.96 (7.26) kg/m2, whereas the average BMI for non-diabetics was 25.93 (7.48) kg/m2. No significant differences were found between the two groups. CONCLUSION: This study provides new insight into the high prevalence of pre-existing T2DM in CRC patients in Saudi Arabia. In particular, the age of diagnosis of CRC in diabetic patients was significantly higher than in non-diabetics.

Immune checkpoint inhibitor-related gastrointestinal toxicity in patients with malignancy involving the luminal gastrointestinal tract and its impact on cancer outcomes.

Background: Immune checkpoint inhibitors (ICI) are known to cause immune-related adverse events (irAE) with the gastrointestinal (GI) tract among the most affected. Our knowledge of GI irAE in patients with luminal GI malignancies is poor. We aimed to characterize the incidence, clinical features, treatment, and outcomes of these GI irAEs. Methods: This was a retrospective study of patients with malignancies involving the luminal GI tract and GI irAEs at MD Anderson Cancer Center from January 2010 to June 2020. Clinical data were collected and analyzed. Results: Eighteen patients with luminal GI tract malignancies treated with ICIs had evidence of GI irAEs based on clinical symptoms and/or histology. The predominant GI irAE symptom was diarrhea (78%). Ten had non-ulcerative inflammation (56%) and 5 had ulcerative inflammation (28%) on endoscopy. Histologically, 3 patients (17%) had evidence of acute inflammation, 4 (22%) had chronic inflammation, and 9 (50%) had both. Ten patients (56%) received immunosuppressant treatment, which included steroids alone (n=2, 20%), steroids with biologics (infliximab or vedolizumab) (n=7, 70%), or biologics alone (n=1, 10%), with clinical remission in all cases. Of the 6 patients who previously had stable or ICI-responsive cancer and received immunosuppressants, none developed progression of GI luminal malignancy during the study period. Conclusions: GI irAEs occurred in 2.4% of patients treated with ICI for cancer involving the luminal GI tract. Immunosuppressant therapies (e.g., vedolizumab) appear to be effective for GI irAEs, showing no association with further GI luminal cancer progression, recurrence, or a subsequent poor response to ICI therapy.

Normative Values for Corneal Tomography and Comparison of Both Eyes in Young Saudi Males with 20/20 Vision Using Pentacam-HR Scheimpflug Imaging.

Purpose: Anterior segment evaluation using Scheimpflug imaging with the Pentacam scanner allows the acquisition of a plethora of information. It aids in screening and diagnosing corneal pathologies and determining suitability for keratorefractive procedures. This research has significant benefits in terms of establishing normative tomographic values, which is crucial in countries where Keratoconus (KC) is more prevalent, especially among young age group, along with aiding future research in the field of refractive surgery by providing relevant normative data. Methods: A retrospective review of digital corneal tomography images for a group of medically and ophthalmologically free males aged between 18 and 21 years with 20/20 unaided distant visual acuity was performed. Results: A total of 1272 subjects (2544 eyes) were included. Findings revealed a mean maximal corneal curvature (Kmax) of 42.91 ± 1.40D (range 36.90-47.80D). The mean flat keratometry (K1) was 41.87 ± 1.31D (range 36.00-46.40D). The mean steep keratometry (K2) was 42.66 ± 1.35D (range 36.70-47.60D). The mean corneal astigmatism (CA) was 0.79 ± 0.37D (range 0.00D-2.30D). The mean central corneal thickness (CCT) was 558.53 ± 33.84 µm (range 421-677 µm). The mean thinnest corneal location thickness (TCLT) was 551.64 ± 34.08 µm (range 417-669µm). The mean corneal diameter (CD) and anterior chamber depth (ACD) were 12.13 ± 0.39 mm (range 10.50-13.60 mm) and 3.12 ± 0.29 mm (range 2.08-4.08 mm), respectively. The median differences between both eyes of the same subject were as follows: kmax difference of 0.20D (IQR 0.1-0.4); K1, K2 and CA difference of 0.20D (IQR 0.1-0.3) for all 3 parameters; CCT and TCLT difference of 5.00 µm (IQR 3.0-9.0) and 6.00 µm (IQR 3.0-10.0), respectively; CD difference of 0.10 mm (IQR 0.0-0.1); and ACD difference of 0.04 (IQR 0.02-0.06). Conclusion: We believe our data can aid in establishing normative tomographic values and acceptable differences between both eyes. Our data may also help detect subtle corneal pathology and be useful for researchers and innovators in the field of ophthalmology.
