Outcome of Cancer Patients with an Unplanned Intensive Care Unit Admission: Predictors of Mortality and Long-term Survival.

Background: Understanding the characteristics and outcomes of cancer patients with unplanned ICU admission is imperative for therapeutic decisions and prognostication purposes. Objective: To describe the clinical characteristics of patients with hematological and non-hematological malignancies (NHM) who require unplanned ICU admission and to determine the predictors of mortality and long-term survival. Methods: This retrospective study included all patients with cancer who had an unplanned ICU admission between 2011 and 2016 at a tertiary hospital in Saudi Arabia. The following variables were collected: age, gender, ICU length of stay (LOS), APACHE II score, type of malignancy, febrile neutropenia, source and time of admission, and need for mechanical ventilation (MV), renal replacement therapy (RRT), and treatment with vasopressors (VP). Predictors of mortality and survival rates at 28 days and 3, 6, and 12 months were calculated. Results: The study included 410 cancer patients with 466 unplanned ICU admissions. Of these, 52% had NHM. The average LOS in the ICU was 9.6 days and the mean APACHE score was 21.9. MV was needed in 73% of the patients, RRT in 15%, and VP in 24%, while febrile neutropenia was present in 24%. There were statistically significant differences between survivors and non-survivors in the APACHE II score (17.7 ± 8.0 vs. 25.6 ± 9.2), MV use (52% vs. 92%), need for RRT (6% vs. 23%), VP use (42% vs. 85%), and presence of febrile neutropenia (18% vs. 30%). The predictors of mortality were need for MV (OR = 4.97), VP (OR = 3.43), RRT (OR = 3.31), and APACHE II score (OR = 1.10). Survival rates at 28 days, 3, 6, and 12 months were 52%, 28%, 22%, and 15%, respectively. Conclusion: The survival rate of cancer patients with an unplanned admission to the ICU remains low. Predictors of mortality include need for MV, RRT, and VP and presence of febrile neutropenia. About 85% of cancer patients died within 1 year after ICU admission.

Prevalence and Risk Factors of Voice Disorders Among Teachers in Saudi Arabia.

Introduction Voice is a crucial tool for communication, and voice problems are more likely to occur in professionals who frequently use their voice for work. Teachers, whose profession requires sustained vocal use, are particularly susceptible to occupation-related voice disorders. This study aimed to quantify the prevalence of voice disorders among teachers in Saudi Arabia, with the general population serving as a control group, and to identify associated risk factors. Methods A cross-sectional study was conducted utilizing an online self-administered questionnaire, which was completed by both teachers and the general population in Saudi Arabia. The latter group acted as a control. The questionnaire included sections on sociodemographic data, teaching patterns, symptoms of voice issues, and the Voice Handicap Index-10 (VHI-10) for assessing voice disorders among participants. Results The study included 640 participants, with 438 (68.4%) being teachers, the majority of whom were females (N = 406; 63.4%). The most common voice-related symptoms reported by teachers were hoarseness (N = 210; 37.9%) and dry throat (N = 147; 26.9%). Voice disorders, as determined by the VHI, affected 355 (55.5%) of the teachers. A high VHI score was associated with a diagnosis of voice disorders and GERD. There was no significant difference in the VHI scores between teachers and the general population (p > 0.05). Conclusion Teachers in Saudi Arabia exhibited a higher prevalence of voice disorders compared to the general population. Risk factors, such as smoking, longer teaching experience, and more teaching hours per week, were more common among teachers with voice disorders. Further investigative studies are warranted to elucidate the causal relationships between these variables and voice disorders.

Resolution of Extensive Xanthomas Associated With Severe Hypertriglyceridemia via Modified Therapeutic Plasma Exchange.

Severe hypertriglyceridemia can be manifested by xanthomas. Therapeutic plasma exchange (TPE) is an invasive medical procedure that has been documented as a viable approach for severe hypertriglyceridemia when cases would be refractory to conventional therapies. TPE is mainly an optional therapeutic modality for cases of severe acute pancreatitis or preventing the recurrence of pancreatitis. Beyond this clinical application, data are scarce on TPE utilization in managing cutaneous lesions associated with hypertriglyceridemia. We present a case of severe hypertriglyceridemia accompanied by extensive xanthomas of various types and a history of recurrent pancreatitis. After conventional therapy failed, a modified plasmapheresis regimen was used and was able to achieve a fast and marked reduction in the patient's serum triglyceride levels with complete resolution of the extensive cutaneous lesions, providing him a newfound comfort he had not experienced in some time and suggesting the regimen potentially could be considered in the treatment of refractory severe hypertriglyceridemia with debilitating cutaneous complications.

Prevalence of Breech Presentation and Other Gestational/Delivery Characteristics Among Patients Born With Developmental Dysplasia of the Hip.

Introduction Developmental dysplasia of the hip (DDH) is the most common congenital disability in newborns. The condition can range from a slight laxity in the hip joint to secondary femoral head injury, early osteoarthritis (OA), and mobility issues. There are several risk factors for DDH, including positive family history, female sex, breech presentation, and the presence of clubfoot. Early detection and treatment are crucial to avoid long-term hip dysplasia and arthritis, which can cause difficulty in walking and discomfort. Breech presentation, in particular, is a significant risk factor for DDH, with spontaneous vaginal birth increasing the risk of hip pathology and instability compared to elective Caesarean section. However, whether breech presentation continues to be a risk factor for DDH in preterm children is unknown. Objective and methods This study aimed to investigate the prevalence of breech presentation and other gestational/delivery characteristics among newborns diagnosed with DDH. This retrospective study was conducted at Abha Maternity and Children Hospital, Abha, Saudi Arabia, over a period of six months. Data were collected from medical records of DDH cases diagnosed between 2016 and 2023. Data analysis was performed using Microsoft Excel (Microsoft Corporation, Redmond, Washington, United States) and IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States). Descriptive statistics and statistical tests were used to analyze the data. Results Most of the diagnosed children were female (86.7%), and bilateral hip dislocation (40%) was the most common presentation. X-ray was the most common diagnostic tool (48.3%), and operative management was the most common management strategy (73.3%). A positive family history of DDH was reported in more than one-third of cases. The study also analyzed the association between complications during pregnancy and various factors such as mode of delivery, presentation at delivery, gestational age at delivery, and associated maternal diseases. The difference in complication rates between women who delivered via C-section and those who delivered vaginally was insignificant (p = 0.14). Similarly, the difference in complication rates between women with breech and cephalic presentation was not statistically significant (p = 0.094). The difference in complication rates between women who delivered preterm, at term, or post-term was also not statistically significant (p = 0.578). Furthermore, the association between complications during pregnancy and pregnancy-associated maternal diseases was not statistically significant (p = 1.00). Conclusion DDH is a significant health issue in newborns, leading to long-term mobility problems and discomfort. Positive family history of DDH is a significant risk factor. Breech presentation was not significantly associated with DDH in preterm children, and no significant associations were found between complications during pregnancy and various factors. Early detection and treatment of DDH are crucial for preventing long-term complications. Family history should be considered an important risk factor, emphasizing the need for screening programs in families with a history of DDH.

Safety and tolerability of Empagliflozin use during the holy month of Ramadan by fasting patients with type 2 diabetes: A prospective cohort study.

Background: Type 2 Diabetes Mellitus (T2DM) patients are exposed to a 7.5 times higher risk of hypoglycemia while fasting during Ramadan. Relevant diabetes guidelines prioritize the use of SGLT2 inhibitors over other classes. There is a great need to enrich data on their safe and effective use by fasting patients at greater risk of hypoglycemia. Therefore, this study aims to assess the safety and tolerability of Empagliflozin in T2DM Muslim patients during Ramadan. Methodology: A prospective cohort study was conducted for adult Muslim T2DM patients. Patients who met the inclusion criteria were categorized into two sub-cohorts based on Empagliflozin use during Ramadan (Control versus Empagliflozin). The primary outcomes were the incidence of hypoglycemia symptoms and confirmed hypoglycemia. Other outcomes were secondary. All patients were followed up to eight weeks post-Ramadan. A propensity score (PS) matching and Risk Ratio (RR) were used to report the outcomes. Results: Among 1104 patients with T2DM who were screened, 220 patients were included, and Empagliflozin was given to 89 patients as an add-on to OHDs. After matching with PS (1:1 ratio), the two groups were comparable. The use of other OHDs, such as sulfonylurea, DPP4 inhibitors, and Biguanides, was not statistically different between the two groups. The risk of hypoglycemia symptoms during Ramadan was lower in patients who received Empagliflozin than in the control group (RR 0.48 CI 0.26, 0.89; p-value = 0.02). Additionally, the risk of confirmed hypoglycemia was not statistically significant between the two groups (RR 1.09 CI 0.37, 3.22; p-value = 0.89). Conclusion: Empagliflozin use during Ramadan fasting was associated with a lower risk of hypoglycemia symptoms and higher tolerability. Further randomized control trials are required to confirm these findings.

Roles and challenges of primary healthcare workers: lessons learned from COVID-19 pandemic.

Context: The COVID-19 pandemic has changed the structure of the healthcare system. As a response to the pandemic, the ministry of health applied many changes to the primary healthcare system. These changes created new challenges for healthcare workers (HCWs). Aims: To identify the roles and challenges of practitioners in primary healthcare (PHC) centers during COVID-19 in Al-Baha city, Saudi Arabia, in 2022. Methods and Materials: An analytical cross-sectional study was carried out in 2022 in Al-Baha city, Saudi Arabia. An electronic online questionnaire was distributed formally to HCWs in PHC centers. All primary HCWs during the COVID-19 pandemic in Al-Baha city, Saudi Arabia, were included. Results: A total of 424 responses were analyzed. Half (50.7%) of the participants had fieldwork roles during the pandemic. The two most commonly agreed-upon challenges were stress (78.7%) and worry about getting infected (79.8%). The majority (74.4%) of the participants' roles involved direct contact with suspected COVID-19 cases, whereas 50.9% involved direct contact with confirmed COVID-19 cases. Direct contact with confirmed cases showed a significant association with worrying about getting infected (P = 0.019). Conclusions: Workload, overtime, conflict ambiguity, fear of getting and transmitting the infection, stress, and lack of personal protective equipment were challenges faced by the primary HCWs, which negatively impacted the quality of delivered services and mental health. We recommend facilitating access of primary HCWs to psychiatric clinics to improve stress and help cope with new roles during the pandemics and changes in the healthcare system.

Perineurial Window is Critical for Experimental Reverse End-to-Side Nerve Transfer.

BACKGROUND: The depth of connective tissue window in the side of a recipient nerve in reverse end-to-side transfers (RETS) remains controversial. OBJECTIVE: To test whether the depth of connective tissue disruption influences the efficiency of donor axonal regeneration in the context of RETS. METHODS: Sprague-Dawley rats (n = 24) were assigned to 1 of the 3 groups for obturator nerve to motor femoral nerve RETS: group 1, without epineurium opening; group 2, with epineurium only opening; and group 3, with epineurium and perineurium opening. Triple retrograde labeling was used to assess the number of motor neurons that had regenerated into the recipient motor femoral branch. Thy1-GFP rats (n = 8) were also used to visualize the regeneration pathways in the nerve transfer networks at 2- and 8-week time point using light sheet fluorescence microscopy. RESULTS: The number of retrogradely labeled motor neurons that had regenerated distally toward the target muscle was significantly higher in group 3 than that in groups 1 and 2. Immunohistochemistry validated the degree of connective tissue disruption among the 3 groups, and optical tissue clearing methods demonstrated donor axons traveling outside the fascicles in groups 1 and 2 but mostly within the fascicles in group 3. CONCLUSION: Creating a perineurial window in the side of recipient nerves provides the best chances of robust donor axonal regeneration across the RETS repair site. This finding aids nerve surgeons by confirming that a deep window should be undertaken when doing a RETS procedure.

Reverse End-to-Side Transfer to Ulnar Motor Nerve: Evidence From Preclinical and Clinical Studies.

The disappointing outcomes of conventional nerve repair or grafting procedures for proximal ulnar nerve injuries have led the scientific community to search for better alternatives. The pronator quadratus branch of the anterior interosseous nerve has been transferred to the distal ulnar motor branch in a reverse end-to-side fashion with encouraging results. This transfer is now becoming commonly used as an adjunct to cubital tunnel decompression in patients with compressive ulnar neuropathy, underscoring the need for this knowledge transfer to the neurosurgical community. However, the mechanism of recovery after these transfers is not understood completely. We have reviewed the existing preclinical and clinical literature relevant to this transfer to summarize the current level of understanding of the underlying mechanisms, define the indications for performing this transfer in the clinic, and identify the complications and best practices with respect to the operative technique. We have also attempted to identify the major deficiencies in our current level of understanding of the recovery process to propose directions for future research.

Successful retrograde regeneration using a sensory branch for motor nerve transfer.

OBJECTIVE: The objective of this study was to test whether regenerating motor axons from a donor nerve can travel in a retrograde fashion using sensory branches to successfully reinnervate a motor nerve end organ. METHODS: This study has two parts. In part I, rats (n = 30) were assigned to one of five groups for obturator nerve (ON)-to-femoral nerve transfer: group 1, ON-to-saphenous nerve (SN) distal stump; group 2, ON-to-SN proximal stump without femoral nerve proper (FNP) injury; group 3, ON-to-SN proximal stump with FNP crush injury; group 4, ON-to-SN proximal stump with FNP transection injury; and group 5, gold standard transfer, ON-to-motor femoral nerve (MFN) branch. At 8 weeks, retrograde labeling was done from the distal MFN, and the spinal cords were examined to assess the degree of obturator motor axon regeneration across the five groups. In part II, only group 4 was examined (n = 8). Through use of immunostaining and optical tissue clearing methods, the nerve transfer networks were cleared and imaged using light-sheet fluorescence microscopy to visualize the regeneration pathways in 2D and 3D models at 2- and 8-week time points. RESULTS: Proximal FNP transection (group 4) enabled a significantly higher number of retrogradely regenerated motor axons compared with control groups 1-3. Moreover, group 4 had modest, but nonsignificant, superiority of motor neuron counts compared with the positive control group, group 5. Optical tissue clearing demonstrated that the axons traveled in a retrograde fashion from the recipient sensory branch to the FNP mixed stump, then through complex turns, down to distal branches. Immunostaining confirmed the tissue clearing findings and suggested perineurium disruption as a means by which axons could traverse across fascicular boundaries. CONCLUSIONS: Sensory branches can transmit regenerating axons from donor nerves back to main mixed recipient nerves, then distally toward target organs. The extent of retrograde regeneration is markedly influenced by the type and severity of injury sustained by the recipient nerve. Using a sensory branch as a bridge for retrogradely regenerating axons can open new potential horizons in nerve repair surgery for severely injured mixed nerves.

Society's Misconceptions About Intra-articular Injections: A Cross-Sectional Study From Saudi Arabia.

Objective This cross-sectional study aimed to identify and analyze misconceptions prevalent in Saudi Arabian society regarding intra-articular injections and their sources. It also sought to explore factors influencing patients' decision-making in the context of osteoarthritis (OA) treatment. Methods A sample of 405 adult participants from various educational backgrounds residing in Saudi Arabia completed a self-administered questionnaire. The survey focused on participants' knowledge about intra-articular injections, their sources of information, and their beliefs and perceptions related to these injections. Results The study unveiled a significant lack of awareness among the participants, with almost half (48.4%) reporting no knowledge of intra-articular injections. Of all, 16.1% held misconceptions about these injections, including believing that they are painful or they liquify the bone. Participants expressed varied thoughts on the effects of intra-articular injections, with 69.6% associating them with short-term pain relief. While 60.2% disagreed that intra-articular injections could provide long-term pain relief, 65.2% believed that these injections could delay the need for surgery. The source of knowledge varied, with 34.4% relying on orthopedics and 32.5% on friends and relatives. In those who had received intra-articular injections (n = 62), 83.9% cited the desire to delay or avoid surgery as a reason. While 56.5% were very satisfied with their doctor's guidance, 46.8% expressed concerns about relying on injections in the future. Furthermore, educational levels were correlated with knowledge, highlighting the need for more accessible and tailored patient education materials. However, even among those with a university education, misconceptions persisted. Effective patient-doctor communication was associated with secondary or university education (χ² = 11.05, p = 0.011). Conclusion The prevalence of misconceptions regarding intra-articular injections in Saudi Arabia underscores the need for comprehensive patient education and improved communication between healthcare providers and patients. Addressing these misconceptions is essential for empowering patients to make informed decisions about their healthcare and enhancing the overall quality of care they receive. This study's findings have implications not only for Saudi Arabia but also for healthcare systems globally, emphasizing the significance of patient-centered care and informed decision-making.

Functional Gait Assessment Using Manual, Semi-Automated and Deep Learning Approaches Following Standardized Models of Peripheral Nerve Injury in Mice.

Objective: To develop a standardized model of stretch−crush sciatic nerve injury in mice, and to compare outcomes of crush and novel stretch−crush injuries using standard manual gait and sensory assays, and compare them to both semi-automated as well as deep-learning gait analysis methods. Methods: Initial studies in C57/Bl6 mice were used to develop crush and stretch−crush injury models followed by histologic analysis. In total, 12 eight-week-old 129S6/SvEvTac mice were used in a six-week behavioural study. Behavioral assessments using the von Frey monofilament test and gait analysis recorded on a DigiGait platform and analyzed through both Visual Gait Lab (VGL) deep learning and standardized sciatic functional index (SFI) measurements were evaluated weekly. At the termination of the study, neurophysiological nerve conduction velocities were recorded, calf muscle weight ratios measured and histological analyses performed. Results: Histological evidence confirmed more severe histomorphological injury in the stretch−crush injured group compared to the crush-only injured group at one week post-injury. Von Frey monofilament paw withdrawal was significant for both groups at week one compared to baseline (p < 0.05), but not between groups with return to baseline at week five. SFI showed hindered gait at week one and two for both groups, compared to baseline (p < 0.0001), with return to baseline at week five. Hind stance width (HSW) showed similar trends as von Frey monofilament test as well as SFI measurements, yet hind paw angle (HPA) peaked at week two. Nerve conduction velocity (NCV), measured six weeks post-injury, at the termination of the study, did not show any significant difference between the two groups; yet, calf muscle weight measurements were significantly different between the two, with the stretch−crush group demonstrating a lower (poorer) weight ratio relative to uninjured contralateral legs (p < 0.05). Conclusion: Stretch−crush injury achieved a more reproducible and constant injury compared to crush-only injuries, with at least a Sunderland grade 3 injury (perineurial interruption) in histological samples one week post-injury in the former. However, serial behavioral outcomes were comparable between the two crush groups, with similar kinetics of recovery by von Frey testing, SFI and certain VGL parameters, the latter reported for the first time in rodent peripheral nerve injury. Semi-automated and deep learning-based approaches for gait analysis are promising, but require further validation for evaluation in murine hind-limb nerve injuries.

Utilization of focused ultrasound for opening of the blood-nerve barrier.

Objective. Focused ultrasound (FUS) use with and without microbubbles (MB) for investigation of the blood-nerve barrier (BNB) within the peripheral nervous system (PNS) has been performed in this study. We evaluate the feasibility of BNB opening in a rodent sciatic nerve model by direct vision FUS treatment and provide preliminary results of magnetic resonance guided FUS (MRgFUS).Approach. Twenty rodent bilateral sciatic nerves were investigated. Rodents were treated using a benchtop FUS system to directly visualize nerve FUS studies. Definity MB, Evans blue dye (EB) and latex micro beads were injected during studies. Selected animals underwent further compound muscle action potential (CMAP) studies. Sonication peak pressure (MPa), width, duty-cycle and duration as well as MB concentration were varied to investigate effective pressure threshold. Further preliminary MRgFUS studies were performed on selected animals. Immunohistochemistry and histological analysis under florescent microscopy were performed at termination of experiments to verify treatment outcomes.Main results. Three ultrasound pressures and three microbubble concentrations at a single sonication frequency (476.5 kHz) were performed under direct open targeting. Histological analysis demonstrated nerve internal architecture disruption at 1.2 MPa with 166.7µl kg-1while 0.3 MPa, with 40µl kg-1MB concentration was the lower threshold for consistently observed disruption of the BNB without anatomical microarchitecture disruption. EB leakage was confirmed at the target region in histological evaluation of nerve following MB injection and FUS sonication. Supra-harmonic emissions were detected during FUS exposures following MB injection but not at baseline reference, indicating effective MB response and stable cavitation. CMAP amplitudes showed delayed onset latency and lower amplitudes in sonicated nerves compared to control nerves without evidence of complete conduction block, suggesting a transient BNB disruption, while at lower limit pressure subtle conduction changes were observed. In MRgFUS, targeted nerves demonstrated further contrast agent leak as well as supra-harmonic frequency detection.Significance. Opening of the BNB in the PNS was achieved using FUS and MB in a rodent model. Ongoing work aims to refine FUS parameters for drug delivery into the nerve after experimental transient BNB disruption.

Comparison of human skin- and nerve-derived Schwann cells reveals many similarities and subtle genomic and functional differences.

Skin is an easily accessible tissue and a rich source of Schwann cells (SCs). Toward potential clinical application of autologous SC therapies, we aim to improve the reliability and specificity of our protocol to obtain SCs from small skin samples. As well, to explore potential functional distinctions between skin-derived SCs (Sk-SCs) and nerve-derived SCs (N-SCs), we used single-cell RNA-sequencing and a series of in vitro and in vivo assays. Our results showed that Sk-SCs expressed typical SC markers. Single-cell sequencing of Sk- and N-SCs revealed an overwhelming overlap in gene expression with the exception of HLA genes which were preferentially up-regulated in Sk-SCs. In vitro, both cell types exhibited similar levels of proliferation, migration, uptake of myelin debris and readily associated with neurites when co-cultured with human iPSC-induced motor neurons. Both exhibited ensheathment of multiple neurites and early phase of myelination, especially in N-SCs. Interestingly, dorsal root ganglion (DRG) neurite outgrowth assay showed substantially more complexed neurite outgrowth in DRGs exposed to Sk-SC conditioned media compared to those from N-SCs. Multiplex ELISA array revealed shared growth factor profiles, but Sk-SCs expressed a higher level of VEGF. Transplantation of Sk- and N-SCs into injured peripheral nerve in nude rats and NOD-SCID mice showed close association of both SCs to regenerating axons. Myelination of rodent axons was observed infrequently by N-SCs, but absent in Sk-SC xenografts. Overall, our results showed that Sk-SCs share near-identical properties to N-SCs but with subtle differences that could potentially enhance their therapeutic utility.

Simultaneous Localized Brain Mild Hyperthermia and Blood-Brain Barrier Opening via Feedback-Controlled Transcranial MR-Guided Focused Ultrasound and Microbubbles.

OBJECTIVE: Non-invasive methods to enhance drug delivery and efficacy in the brain have been pursued for decades. Focused ultrasound hyperthermia (HT) combined with thermosensitive therapeutics have been demonstrated promising in enhancing local drug delivery to solid tumors. We hypothesized that the presence of microbubbles (MBs) combined with transcranial MR-guided focused ultrasound (MRgFUS) could be used to reduce the ultrasound power required for HT while simultaneously increasing drug delivery by locally opening the blood-brain barrier (BBB). METHODS: Transcranial HT (42 °C, 10 min) was performed in wild-type mice using a small animal MRgFUS system incorporated into a 9.4T Bruker MR scanner, with infusions of saline or Definity MBs with doses of 20 or 100 µl/kg/min (denoted as MB-20 and MB-100). MR thermometry data was continuously acquired as feedback for the ultrasound controller during the procedure. RESULTS: Spatiotemporally precise transcranial HT was achieved in both saline and MB groups. A significant ultrasound power reduction (-45.7%, p = 0.006) was observed in the MB-20 group compared to saline. Localized BBB opening was achieved in MB groups confirmed by CE-T1w MR images. There were no structural abnormalities, edema, hemorrhage, or acutemicroglial activation in all groups, confirmed by T2w MR imaging and histology. CONCLUSION: Our investigations showed that it is feasible and safe to achieve spatiotemporally precise brain HT at significantly reduced power and simultaneous localized BBB opening via transcranial MRgFUS and MBs. SIGNIFICANCE: This study provides a new synergistic brain drug delivery method with clinical translation potential.

Internalized Weight Stigma: Prevalence and Association With Psychiatric Disorder Among Overweight and Obese Individuals.

Background and objective Unlike weight stigma, internalized weight stigma (IWS) may be a common but still underreported problem. With the recent emergence of studies investigating its various aspects in Arab-speaking countries, there is still scant data on its incidence and severity in the literature. In light of this, the aim of this study was to evaluate the prevalence of IWS and its association with psychiatric disorders and sociodemographic factors among overweight and obese individuals in a sample from a Saudi population. Methods A cross-sectional study was conducted among a Saudi population using a convenience sample technique and 868 individuals were enrolled to participate in this study. They were asked to fill out an electronic questionnaire about IWS, demographics, and other parameters such as Patient Health Questionnaire (PHQ)-9 and General Anxiety Disorder (GAD)-7. The association was tested using an independent t-test and chi-square test. Results The overall prevalence of internalized stigma in this study was 57%. Higher levels of internalization were more prevalent among younger respondents. We found that females were more prone to internalize weight stigma, at a slightly higher rate than males (59.26% vs. 53.66%), but this difference was not statistically significant. The other sociodemographic factors associated with higher internalization were as follows: being widowed, married, retired, or housewife. Those with higher IWS levels were individuals with higher BMI and with previous experiences of weight stigma. In addition, higher internalization was associated with the development of severe depression and anxiety (p<0.001). Conclusion The prevalence of IWS among overweight and obese individuals was found to be high, and it is highly associated with the development of severe depression and anxiety. There is a need to raise awareness about obesity stigma to help tackle IWS in overweight and obese individuals and to promote their quality of life.

Surgical Management of Abdominal Anterior Cutaneous Nerve Entrapment Syndrome: Case Report, Surgical Technique, and Literature Review.

Abdominal anterior cutaneous nerve entrapment syndrome (ACNES) is an emerging diagnosis, with estimated incidence of 13%-30% of the adult population. It is a syndrome characterized by chronic abdominal pain caused by entrapment of cutaneous branches of thoracoabdominal nerves at the lateral border of the rectus abdominis muscle. If conservative treatment with pain medication, botulinum toxin, or lidocaine injections is inadequate, surgical management is indicated. METHODS: We present a case of a 40-year-old woman presenting with a 1-year history of daily right anterior abdominal wall pain, consistent with a diagnosis of ACNES. We describe our approach for an anterior neurectomy of the intercostal nerve with closure of its fascial foramen. RESULTS: Three months after surgery, she remained pain free and was back to work full time. At a 13-month follow-up, the patient reported that her pain had resolved completely following surgery. CONCLUSIONS: Results are encouraging following anterior neurectomy for ACNES. Surgical descriptions in the literature are brief, with limited pictorial account. Our detailed surgical approach is provided along with a review of the existing literature on the management of ACNES.

Analysis of the effect of intraoperative neuromonitoring during resection of benign nerve sheath tumors on gross-total resection and neurological complications.

OBJECTIVE: The aim of this study was to examine the role of intraoperative neuromonitoring (IONM) during resection of benign peripheral nerve sheath tumors in achieving gross-total resection (GTR) and in reducing postoperative neurological complications. METHODS: Data from consecutive adult patients who underwent resection of a benign peripheral nerve sheath tumor at 7 participating institutions were combined. Propensity score matching was used to balance covariates. The primary outcomes of interest were the association between IONM and GTR and the association of IONM and the development of a permanent postoperative neurological complication. The secondary outcomes of interest were the association between IONM and GTR and the association between IONM and the development of a permanent postoperative neurological complication in the subgroup of patients with tumors involving a motor or mixed nerve. Univariate and multivariate logistic regression were then performed on the propensity score-matched samples to assess the ability of the independent variables to predict the outcomes of interest. RESULTS: A total of 337 patients who underwent resection of benign nerve sheath tumors were included. In multivariate analysis, the use of IONM (OR 0.460, 95% CI 0.199-0.978; p = 0.047) was a significant negative predictor of GTR, whereas none of the variables, including IONM, were associated with the occurrence of a permanent postoperative neurological complication. Within the subgroup of motor/mixed nerve tumors, in the multivariate analysis, IONM (OR 0.263, 95% CI 0.096-0.723; p = 0.010) was a significant negative predictor of a GTR, whereas IONM (OR 3.800, 95% CI 1.925-7.502; p < 0.001) was a significant positive predictor of a permanent postoperative motor deficit. CONCLUSIONS: Overall, 12% of the cohort had a permanent neurological complication, with new or worsened paresthesias most common, followed by pain and then weakness. The authors found that formal IONM was associated with a reduced likelihood of GTR and had no association with neurological complications. The authors believe that these data argue against IONM being considered standard of care but do not believe that these data should be used to universally argue against IONM during resection of benign nerve sheath tumors.

Clinical features and therapeutic outcomes of patients with acromegaly in Saudi Arabia: a retrospective analysis.

BACKGROUND: Acromegaly is a rare disease resulting in clinical sequelae with significant morbidity and mortality due to the central tumor mass effect and prolonged growth hormone (GH) hypersecretion. OBJECTIVES: The goal is to describe the epidemiology, clinical features, presence of comorbidities, and treatment outcomes of acromegaly in Saudi Arabia. METHODS: Data was collected through a retrospective review of the charts of all patients diagnosed with acromegaly from nine major hospitals in Saudi Arabia over a period of more than 25 years. RESULTS: A total of 195 patients (116 males and 79 females), with a mean age at diagnosis of 43 ± 12 (males) and 46 ± 14 years (females), from nine major hospitals were identified and included in the analysis. All cases were caused by pituitary adenomas, of which 92.4% were macroadenomas. Headache, coarse facial features, acral growth, and sweating/oily skin were by far the most frequent presenting complaints. The most common comorbidities were diabetes mellitus (51.7%), followed by hypertension (50%) and visual field defect (30.5%). The vast majority (95%) of patients were treated surgically (98%). Twenty-four percent also received radiotherapy, and 74.4% received medical therapy. When stringent criteria were applied for assessment of outcomes of therapy, 28.7% of the patients were cured and 30.1% had their disease under control, while 28.7% were found to have active disease despite receiving multimodal therapy. CONCLUSIONS: Our findings highlight the need for a national acromegaly registry to enable early identification, evaluation, and selection of the best therapeutic approaches to improve the outcome and remission rate of the disease.

Identification and Characterization of Salt-Responsive MicroRNAs in Vicia faba by High-Throughput Sequencing.

Salt stress has detrimental effects on plant growth and development. MicroRNAs (miRNAs) are a class of noncoding RNAs that are involved in post-transcriptional gene expression regulation. In this study, small RNA sequencing was employed to identify the salt stress-responsive miRNAs of the salt-sensitive Hassawi-3 and the salt-tolerant ILB4347 genotypes of faba bean, growing under salt stress. A total of 527 miRNAs in Hassawi-3 plants, and 693 miRNAs in ILB4347 plants, were found to be differentially expressed. Additionally, 284 upregulated and 243 downregulated miRNAs in Hassawi-3, and 298 upregulated and 395 downregulated miRNAs in ILB4347 plants growing in control and stress conditions were recorded. Target prediction and annotation revealed that these miRNAs regulate specific salt-responsive genes, which primarily included genes encoding transcription factors and laccases, superoxide dismutase, plantacyanin, and F-box proteins. The salt-responsive miRNAs and their targets were functionally enriched by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses, which showed that the miRNAs were involved in salt stress-related biological pathways, including the ABC transporter pathway, MAPK signaling pathway, plant hormone signal transduction, and the phosphatidylinositol signaling system, among others, suggesting that the miRNAs play an important role in the salt stress tolerance of the ILB4347 genotype. These results offer a novel understanding of the regulatory role of miRNAs in the salt response of the salt-tolerant ILB4347 and the salt-sensitive Hassawi-3 faba bean genotypes.
