ABSTRACT

Adipocyte P2 (aP2), also known as FABP4, is an adipokine that adipose tissue produces and expresses in macrophages. Its primary role is to facilitate the transportation of fatty acids across cell membranes. Numerous studies have reported associations between FABP4 and the development of metabolic disorders. However, there is limited knowledge regarding FABP4 expression in diabetes and obesity, especially about different age groups, genders, and ethnicities. This study aims to investigate the association between FABP4 levels, diabetes mellitus, and obesity within various ethnic groups. We measured plasma FABP4 concentrations in a cohort of 2083 patients from the KDEP study and gathered anthropometric data. Additionally, we collected and analyzed clinical, biochemical, and glycemic markers using multivariate regression analysis. The average FABP4 concentration was significantly higher in female participants than in males (18.8 ng/mL vs. 14.4 ng/mL, p < 0.001, respectively), and in those over 50 years old compared to those under 50 years of age (19.3 ng/mL vs. 16.2 ng/mL, p < 0.001, respectively). In this study, significant positive associations were found between the plasma level of FABP4 and obesity markers: BMI (r = 0.496, p < 0.001), hip circumference (r = 0.463, p < 0.001), and waist circumference (WC) (r = 0.436, p < 0.001). Similar observations were also seen with glycemic markers, which included HbA1c (r = 0.126, p < 0.001), fasting blood glucose (FBG) (r = 0.184, p < 0.001), fasting insulin (r = 0.326, p < 0.001), and HOMA-IR (r = 0.333, p < 0.001). Importantly, these associations remained significant even after adjusting for age, gender, and ethnicity. Furthermore, FABP4 levels were negatively associated with male gender (ß: -3.85, 95% CI: -4.92, -2.77, p < 0.001), and positively associated with age (ß: 0.14, 95% CI: 0.096, 0.183, p < 0.001), BMI (ß: 0.74, 95% CI: 0.644, 0.836, p < 0.001), and fasting insulin (ß: 0.115, 95% CI: 0.091, 0.138, p < 0.001). In this study, plasma FABP4 levels were significantly higher in diabetic and obese participants, and they were strongly influenced by age, gender, and ethnicity. These findings suggest that FABP4 may serve as a valuable prognostic and diagnostic marker for obesity and diabetes, particularly among female patients, individuals over 50 years old, and specific ethnic groups.

ABSTRACT

Obesity has become a global epidemic in the modern world, significantly impacting the global healthcare economy. Lifestyle interventions remain the primary approach to managing obesity, with medical therapy considered a secondary option, often used in conjunction with lifestyle modifications. In recent years, there has been a proliferation of newer therapeutic agents, revolutionizing the treatment landscape for obesity. Notably, glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, liraglutide, and the recently approved dual GLP-1/GIP RAs agonist tirzepatide, have emerged as effective medications for managing obesity, resulting in significant weight loss. These agents not only promote weight reduction but also improve metabolic parameters, including lipid profiles, glucose levels, and central adiposity. On the other hand, bariatric surgery has demonstrated superior efficacy in achieving weight reduction and addressing overall metabolic imbalances. However, with ongoing technological advancements, there is an ongoing debate regarding whether personalized medicine, targeting specific components, will shape the future of developing novel therapeutic agents for obesity management.

ABSTRACT

Mycetoma is a serious, destructive, disfiguring chronic granulomatous inflammatory disease affecting the subcutaneous tissues that spread to involve the skin, deep tissues and bone. The disease predominately affects the limbs, and extrapedal mycetoma is rarely reported. The reported extrapedal ones are characterised by high morbidity and mortality. This communication reports on 420 patients with extrapedal mycetoma seen and managed at the Mycetoma Research Centre (MRC), University of Khartoum, between January 1991 and December 2021. In this descriptive, cross-sectional, hospital-based study, the electronic records of all mycetoma-confirmed patients seen during the study period were carefully and meticulously reviewed. The confirmed patients with extrapedal mycetoma were included in this study. The study included 420 patients with extrapedal mycetoma, 298 (70.7%) had eumycetoma, and 122 (29.3%) had actinomycetoma. There were 343 male patients (81.7%) and 77 (18.3%) females, with a male-to-female ratio of 4:1. Their ages ranged between 1.5 and 95 years, with a median of 28 years. Most of the patients were students and farmers. The majority of patients were from El Gezira, North Kordofan, and the White Nile States. Mycetoma was painful in 21%, and a family history of mycetoma was recorded in 11.5% of patients. The buttocks (37.9%) and head and neck (16.9%) were affected most. Less frequently affected sites were the trunk and back (12%) each, abdominal and chest walls (4.5%) each and loin (1%). The prominent clinical presentation findings were multiple sinuses discharging grains (55%), massive swellings (46%), and lymphadenopathy (11.5%). Less commonly observed clinical findings were local hyperhidrosis (5.3%) and dilated tortuous veins close to mycetoma lesions (0.5%). The study showed that 204 patients (48.6%) had clinical improvement in terms of decreased lesion size and healing of sinuses following medical therapy. Sixty-six patients (15.7%) had no noticeable improvement. The lesion continued progressing despite treatment in 44 patients (10.5%). In the study, 118 patients were on regular follow-up, and in this group, a cure was documented in 25 patients (21.1%) with eumycetoma and 23 (19.4%) with actinomycetoma. Post-operative recurrence among eumycetoma patients was 40%, with a 1% mortality rate. The treatment outcome was unsatisfactory, characterised by a low cure rate, high recurrence (40%) and follow-up dropout (57%) rates. This emphasises the importance of early case detection and management, objective health education programmes and thorough patient counselling to urge people to seek treatment early and reduce dropouts.

ABSTRACT

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a complex endocrine condition affecting women of reproductive age. It is characterised by insulin resistance and is a risk for type 2 diabetes mellitus (T2DM). The aim of this study was to review the literature on the effect of pioglitazone and rosiglitazone in women with PCOS. METHODS: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane Library and the Web of Science in April 2020 and updated in March 2023. Studies were deemed eligible if they were randomised controlled trials (RCTs) reporting the effect of pioglitazone and rosiglitazone in PCOS. The study follows the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two reviewers independently extracted data and assessed the risk of bias using the Cochrane risk of bias tool. RESULTS: Out of 814 initially retrieved citations, 24 randomised clinical trials (RCTs) involving 976 participants were deemed eligible. Among women with PCOS, treatment with rosiglitazone compared to metformin resulted in a significant increase in the mean body weight (mean difference (MD) 1.95 kg; 95% CI 0.03-3.87, p = 0.05). Metformin treatment was associated with a reduction in mean body mass index (BMI) compared to pioglitazone (MD 0.85 kg/m2; 95% CI 0.13-1.57, p = 0.02). Both pioglitazone compared to placebo (MD 2.56 kg/m2; 95% CI 1.77-3.34, p < 0.00001) and rosiglitazone compared to metformin (MD 0.74 kg/m2; 95% CI 0.07-1.41, p = 0.03) were associated with a significant increase in BMI. Treatment with pioglitazone compared to placebo showed a significant reduction in triglycerides (MD - 0.20 mmol/L; 95% CI - 0.38 to - 0.03, p = 0.02) and fasting insulin levels (MD - 11.47 mmol/L; 95% CI - 20.20, - 2.27, p = 0.01). Rosiglitazone compared to metformin was marginally significantly associated with a reduction in the luteinising hormone (LH) (MD - 0.62; 95% CI - 1.25-0.00, p = 0.05). CONCLUSION: Both pioglitazone and rosiglitazone were associated with significant increases in body weight and BMI when compared with metformin or placebo. Pioglitazone significantly reduced triglycerides and fasting insulin when compared with placebo while rosiglitazone showed a modest reduction of LH when compared with metformin.

ABSTRACT

Background: Cutaneous Leishmaniasis (CL) is a vector-borne skin infection that remains prevalent in regions with poor socioeconomic conditions. Stigmatization occurs when individuals with physical or psychological disorders interact with societal stereotypes. The aim of this study was to explore the perceived social stigma surrounding CL among people residing in Hubuna, Saudi Arabia. Methods: This cross-sectional community-based survey recruited 618 individuals aged 18 years and above using the snowball sampling technique to reach hidden cases within the target population. Data was collected using a self-administered questionnaire and the Explanatory Model Interview Catalogue for Perceived Social Stigma (EMIC-SS-12) was used to assess the level of perceived social stigma. It includes questions on demographic variables, behaviors, and experiences. The analysis was performed using SPSS. Results: The study included 618 participants, the majority of whom were women and girls (54.2%), with a mean age of 28 ± 12.7 years. The median score for perceived social stigma was 26.0. Only 2.1% (n = 13) of participants had the highest EMIC-SS-12 score of 36, while 7.6% (n = 47) scored zero. The mean score for overall perceived social stigma was 1.89 ± 0.91, while the mean score for experienced stigma was 1.99 ± 1.02. Univariate analysis showed that sex, employment, location of lesions, and number of lesions were insignificantly associated with stigmatization (P-value < 0.05), because these associations were uncertain because the CI includes or very close to 1. Conclusion: The study reveals insights into stigmatization associated with CL in the Habuna area of Saudi Arabia. It found that the median of perceived social stigma was 26. Factors such as sex, employment status, and location of the lesion are uncertainly associated with stigma. It is crucial to explore negative behaviors and perceptions and develop suitable health education programs.

ABSTRACT

Postoperative ileus (POI) is the leading cause of prolonged hospital stay after abdominal surgery and is characterized by a functional paralysis of the digestive tract, leading to symptoms such as constipation, vomiting, and functional obstruction. Current treatments are mainly supportive and inefficacious and yield acute side effects. Although electrical stimulation studies have demonstrated encouraging pacing and entraining of the intestinal slow waves, no devices exist today to enable targeted intestinal reanimation. Here, we developed an ingestible self-propelling device for intestinal reanimation (INSPIRE) capable of restoring peristalsis through luminal electrical stimulation. Optimizing mechanical, material, and electrical design parameters, we validated optimal deployment, intestinal electrical luminal contact, self-propelling capability, safety, and degradation of the device in ex vivo and in vivo swine models. We compared the INSPIRE's effect on motility in models of normal and depressed motility and chemically induced ileus. Intestinal contraction improved by 44% in anesthetized animals and up to 140% in chemically induced ileus cases. In addition, passage time decreased from, on average, 8.6 days in controls to 2.5 days with the INSPIRE device, demonstrating significant improvement in motility. Luminal electrical stimulation of the intestine via the INSPIRE efficaciously restored peristaltic activity. This noninvasive option offers a promising solution for the treatment of ileus and other motility disorders.

ABSTRACT

Calciphylaxis, also known as Calcific uremic arteriolopathy (CUA), is a serious disorder that presents with skin necrosis due to calcification of dermal and subcutaneous adipose tissue capillaries and arterioles. The condition occurs primarily in patients with end-stage renal disease (ESRD) on dialysis, and it carries high morbidity and mortality, primarily due to sepsis, with an estimated six-month survival of approximately 50%. Although there are no high-quality studies to guide the optimal treatment approach for patients with calciphylaxis, many retrospective studies and case series support treatment with sodium thiosulfate (STS). Despite the frequent use of STS as an off-label treatment, data regarding its safety and efficacy are limited. STS has generally been considered a safe drug with mild side effects. However, severe metabolic acidosis associated with STS is a rare and life-threatening complication of STS treatment and is often unpredictable. Herein, we report a 64-year-old female with ESRD on peritoneal dialysis (PD) who presented with a profound high anion gap metabolic acidosis and severe hyperkalemia while on STS treatment for CUA. No other etiology for her severe metabolic acidosis other than STS was identified. ESRD patients receiving STS should be monitored closely for this side effect. Dose reduction, increasing the duration of infusion, or even discontinuing STS treatment should be considered if severe metabolic acidosis develops.

ABSTRACT

Effective therapies for obesity require invasive surgical and endoscopic interventions or high patient adherence, making it challenging for patients with obesity to effectively manage their disease. Gastric mechanoreceptors sense distension of the stomach and perform volume-dependent vagal signaling to initiate the gastric phase and influence satiety. In this study, we developed a new luminal stimulation modality to specifically activate these gastric stretch receptors to elicit a vagal afferent response commensurate with mechanical distension. We designed the Vibrating Ingestible BioElectronic Stimulator (VIBES) pill, an ingestible device that performs luminal vibratory stimulation to activate mechanoreceptors and stroke mucosal receptors, which induces serotonin release and yields a hormonal metabolic response commensurate with a fed state. We evaluated VIBES across 108 meals in swine which consistently led to diminished food intake (~40%, P < 0.0001) and minimized the weight gain rate (P < 0.05) as compared to untreated controls. Application of mechanoreceptor biology could transform our capacity to help patients suffering from nutritional disorders.

ABSTRACT

This case report describes the presentation, diagnosis, and surgical management of a rare vesical ectopic pregnancy in a 36-year-old woman with a history of multiple cesarean sections. The patient presented with symptoms of suprapubic pain, fever, and amenorrhea. An initial ultrasound indicated retained products of conception, leading to a preliminary diagnosis of septic miscarriage. However, subsequent rescanning revealed an empty uterus and a non-viable fetus within the bladder, connected to the uterine cavity. Cystoscopy confirmed the presence of fetal parts inside the bladder. Finally, a laparotomy was performed and the fetus was removed from the bladder with repair of the underlying uterovesical fistula. An uneventful postoperative period ensued. The literature review revealed only four previously reported cases with similar overall presentations. This case highlights the importance of considering vesical ectopic pregnancies in patients with a history of cesarean sections and unusual symptoms, as prompt surgical intervention is crucial for ensuring successful management of the condition.

ABSTRACT

KIF20A is a critical kinesin for cell division and a promising anti-cancer drug target. The mechanisms underlying its cellular roles remain elusive. Interestingly, unusual coupling between the nucleotide- and microtubule-binding sites of this kinesin-6 has been reported, but little is known about how its divergent sequence leads to atypical motility properties. We present here the first high-resolution structure of its motor domain that delineates the highly unusual structural features of this motor, including a long L6 insertion that integrates into the core of the motor domain and that drastically affects allostery and ATPase activity. Together with the high-resolution cryo-electron microscopy microtubule-bound KIF20A structure that reveals the microtubule-binding interface, we dissect the peculiarities of the KIF20A sequence that influence its mechanochemistry, leading to low motility compared to other kinesins. Structural and functional insights from the KIF20A pre-power stroke conformation highlight the role of extended insertions in shaping the motor's mechanochemical cycle. Essential for force production and processivity is the length of the neck linker in kinesins. We highlight here the role of the sequence preceding the neck linker in controlling its backward docking and show that a neck linker four times longer than that in kinesin-1 is required for the activity of this motor.

ABSTRACT

Purpose: Although there is an established role for microbiome dysbiosis in the pathobiology of colorectal cancer (CRC), CRC patients of various race/ethnicities demonstrate distinct clinical behaviors. Thus, we investigated microbiome dysbiosis in Egyptian, African American (AA), and European American (EA) CRC patients. Patients and methods: CRCs and their corresponding normal tissues from Egyptian (n = 17) patients of the Alexandria University Hospital, Egypt, and tissues from AA (n = 18) and EA (n = 19) patients at the University of Alabama at Birmingham were collected. DNA was isolated from frozen tissues, and the microbiome composition was analyzed by 16S rRNA sequencing. Differential microbial abundance, diversity, and metabolic pathways were identified using linear discriminant analysis (LDA) effect size analyses. Additionally, we compared these profiles with our previously published microbiome data derived from Kenyan CRC patients. Results: Differential microbiome analysis of CRCs across all racial/ethnic groups showed dysbiosis. There were high abundances of Herbaspirillum and Staphylococcus in CRCs of Egyptians, Leptotrichia in CRCs of AAs, Flexspiria and Streptococcus in CRCs of EAs, and Akkermansia muciniphila and Prevotella nigrescens in CRCs of Kenyans (LDA score >4, adj. p-value <0.05). Functional analyses showed distinct microbial metabolic pathways in CRCs compared to normal tissues within the racial/ethnic groups. Egyptian CRCs, compared to normal tissues, showed lower l-methionine biosynthesis and higher galactose degradation pathways. Conclusions: Our findings showed altered mucosa-associated microbiome profiles of CRCs and their metabolic pathways across racial/ethnic groups. These findings provide a basis for future studies to link racial/ethnic microbiome differences with distinct clinical behaviors in CRC.

ABSTRACT

Effective therapies for obesity either require invasive surgical or endoscopic interventions or high patient adherence, making it challenging for the nearly 42% of American adults who suffer from obesity to effectively manage their disease. Gastric mechanoreceptors sense distension of the stomach and perform volume-dependent vagal signaling to initiate the gastric phase and influence satiety. In this study, we developed a new luminal stimulation modality to specifically activate these gastric stretch receptors to elicit a vagal afferent response commensurate with mechanical distension. Here we developed the Vibrating Ingestible BioElectronic Stimulator (VIBES) pill - an ingestible device that performs luminal vibratory stimulation to activate mechanoreceptors and stroke mucosal receptors, which induces serotonin release as well as yields a hormonal metabolic response commensurate with a fed state. We evaluated VIBES across 108 meals in swine which consistently led to diminished food intake (~40%, p< 0.0001) and minimized the weight gain rate (p< 0.03) as compared to untreated controls. Application of mechanoreceptor biology could transform our capacity to help patients suffering from nutritional disorders.

ABSTRACT

Background and Objectives: Salivary gland tumors (SGTs) are serious challenges to pathologists. Herein, we aimed to assess epidemiological and histopathological characteristics of SGTs among Sudanese patients. Materials and Methods: This retrospective descriptive study was undertaken at The pathology department in Khartoum State between 2008 and 2018. Patient records, histopathological reports, and slides were retrieved; and re-examined by two histopathologists. Diagnoses were reclassified according to the 2017 WHO classification of SGTs. Results: Overall, 150 cases of Sudanese patients with SGT were included (90 [60%] males and 60 [40%] females). Among these, 105 were benign (70%) and 45 were malignant (30%). The parotid glands were the most common site for both benign and malignant tumors (77/150; 51%: 59 benign (76.6%) and 18 malignant [23.4%]). The next common site was the submandibular gland (54 [36%]: 38 benign [70.3%] and 16 malignant [29.7%]), followed by minor salivary glands (19 [12.7%]: 8 benign and 11 malignant [57.9%]). Benign gland entities included pleomorphic adenoma (88/105; 83.7%), oncocytoma (5/105; 4.8%), myoepithelioma (4/105; 3.8%), Whartin tumors (3/105; 2.9%), basal cell adenoma (3/105; 2.9%), and sialolipoma (2/105; 1.9%). Malignant gland entities included adenoid cystic carcinoma (12; 26.7%), mucoepidermoid carcinoma (10; 22,2%), acinic cell carcinoma (6; 13.3%), poorly differentiated carcinoma (4; 8.9%), adenocarcinoma NOS (not otherwise specified) (4; 8.9%), basal cell adenocarcinoma (3; 6.7%), carcinoma ex pleomorphic adenoma (3; 6.7%), polymorphous adenocarcinoma (2; 4.4%), salivary duct carcinoma (1; 2.2%), and epithelial-myoepithelial carcinoma (2.2%). Conclusions: SGTs shared several epidemiological and histopathological features, exhibiting high incidence in the parotid and submandibular glands, lower prevalence in minor glands, and greater male predominance.

ABSTRACT

Commiphora gileadensis (C. gileadensis) has been identified and linked with various health benefits and pharmaceutical potential for its phytochemical activities and chemical constituents. This study aimed to evaluate ultrasonic-assisted extraction (USE) technique for total phenols content from C. gileadensis leaf compared to the hydrodistillation extraction (HDE). Our results showed that the USE operating conditions were identified as: MeOH·H2O solvent-to-fresh sample ratio of 80:20 (v/v); ultrasonic power/frequency at 150 W/20 kHz; and a temperature of 40 ± 1°C; subjected to acoustic waves intermittently for a calculated time (5 min) during the total programmed time of 12 min. The USE exhibited (118.71 ± 0.009 mg GAE/g DM) more amounts of all phenols than HDE (101.47 ± 0.005 mg GAE/g DM), and antioxidant (77.78 ± 0.73%, 75.27 ± 0.59% scavenging inhibition of DPPH), respectively. Anti-aging and Cytotoxicity activities were investigated. The results of biological evaluations showed that the crude extracts of C. gileadensis significantly extended the replicative lifespan of K6001 yeast. In addition, in vitro cytotoxicity against the HepG2 cell line showed significant anticancer activity, and approximately 100 µg/mL is required to decrease viability compared with that of the control. This study is proven for a larger scale to extract and isolate compounds of C. gileadensis for potential utilization in the pharmaceutical industry. In conclusion, advanced methods afford an extract with high activity in the biological properties of the extract.

ABSTRACT

Norovirus (NoV) is one of the most common causes of acute infectious gastroenteritis in the United States (US). The infection is typically short-lasting and self-limiting in immunocompetent hosts. Renal transplant recipients on immunosuppressive therapy are more prone to infectious gastroenteritis that can be caused by various common and opportunistic organisms. NoV infection in renal transplant patients presents as an acute diarrheal illness that may progress to a chronic infection with frequent relapses leading to adverse short-term complications (acute renal injury (AKI) and acute graft rejection from the reduction of the dose of immunosuppressive medications) and possibly long-term morbidities (malabsorption syndrome, and a decline in graft survival). The management of chronic NoV infections in renal transplant patients may be quite challenging, as no specific antiviral treatment is presently approved, and frequent adjustments of immunosuppressive therapy may be required in the setting of reduced renal clearance and the attempts to decrease immunosuppressive effects to enhance the viral clearance.Herein, the authors present a case of persistent NoV in a young female patient with a renal transplant that was associated with recurrent admissions with AKI, gross electrolyte disturbances, and significant weight loss. The relapsing NoV infection has negatively impacted the patient's quality of life and socioeconomic performance.

ABSTRACT

Osteoarticular infections (OAIs) caused by Gemella morbillorum (G. morbillorum) are a rare clinical entity. This study aimed to review all published cases of OAI due to G. morbillorum. A systematic review of PubMed, Scopus, and Cochrane Library was conducted to report the demographic and clinical characteristics, microbiological data, management, and outcome of OAIs caused by G. morbillorum in the adult population. A total of 16 studies reporting on 16 patients were included in this review. Eight patients had arthritis and eight patients had osteomyelitis/discitis. The most reported risk factors were immunosuppression, poor dental hygiene/dental infections, and recent gastrointestinal (GI) endoscopy. Five cases of arthritis occurred in a native joint while three patients had prostheses. The potential source of G. morbillorum infection was documented in more than half of the cases (56%) (most commonly odontogenic and GI sources (25% and 18%, respectively). The knee and hip joints were the most frequently affected joints in patients with arthritis, while the thoracic vertebrae were the most common sites for osteomyelitis/discitis. The blood cultures were positive in three patients with arthritis (37.5%) and five patients with osteomyelitis/discitis (62.5%). Associated endovascular infection was found in five patients with bacteremia. Contiguous spread (adjacent mediastinitis) was documented in two patients with sternal osteomyelitis and thoracic vertebral osteomyelitis. Surgical interventions were performed for 12 patients (75%). Most strains of G. morbillorum were susceptible to penicillin and cephalosporins. All patients with reported outcomes had achieved complete recovery. G. morbillorum is an emerging pathogen for OAIs in certain susceptible populations with specific risk factors. This review reported the demographic, clinical, and microbiological features of OAIs caused by G. morbillorum. A careful evaluation of an underlying infectious focus is warranted to control the source. When G. morbillorum bacteremia is present, it is also necessary to have a high index of suspicion to rule out an associated endovascular infection.

ABSTRACT

Non-tuberculous mycobacteria (NTM) are ubiquitous organisms in the environment that can potentially cause a range of pulmonary and extrapulmonary infections in humans. Epidemiological risk factors and the host's immune status determine the susceptibility to various clinical syndromes caused by different NTM species. Non-tuberculous mycobacteria pulmonary disease (NTM-PD) is primarily reported in patients with underlying lung disease. These infections often pose a significant disease burden on affected patients as they are often chronic, difficult to treat, and necessitate long-term multi-drug therapy. Mycobacterium avium complex (MAC) is the most common causative pathogen of NTM-PD in the USA, followed by Mycobacterium kansasii (M. kansasii). Less common species in the USA include Mycobacterium xenopi (M. xenopi), Mycobacterium abscessus, and others, largely depending upon the geographic location and exposure to species-specific predisposing risks. In this case series, the authors report on three elderly patients with chronic lung diseases who had pulmonary NTM disease caused by M. xenopi and MAC. The patients were encountered in both inpatient and outpatient settings from a community-based hospital in the midwestern USA. The clinical and radiological features of NTM-PD masqueraded as malignancy and posed a diagnostic dilemma. The epidemiology, clinical and radiological features, diagnosis, and management of NTM-PD are reviewed in this report.

ABSTRACT

Percutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure that represents an important supportive adjunctive component for patients with primary head and neck squamous cell carcinoma (HNSCC). The HNSCC population is considered a high-risk group for developing critical nutritional deficiency due to a multitude of factors. Nevertheless, as the use of PEG in modern practice is gaining more popularity due to various indications, unusual complications have been increasingly reported. PEG site metastasis from primary HNSCC has emerged as a rare, yet serious oncological phenomenon that warrants careful consideration. The authors report an unusual case of squamous cell carcinoma (SCC) of the hypopharynx that metastasized to the gastric body mucosa through a PEG site. The metastatic SCC presented as massive gastrointestinal bleeding, and esophagogastroscopy revealed an ulcerated mass in the gastric body masquerading as a primary gastric adenocarcinoma. Histopathology and immunohistochemistry examination confirmed metastatic SCC which concurred with the patient's primary hypopharyngeal SCC. The review of the updated literature revealed that a total of 121 cases of this rare oncological entity have been reported to date. Physicians need to be vigilant of the symptoms of PEG site metastasis to accurately diagnose and manage the care of this rare occurrence as it is associated with poor prognosis.

ABSTRACT

Intracranial hemorrhage, including subarachnoid hemorrhage (SAH), is associated with many cardiac effects, including cardiac rhythm abnormalities, ischemic electrocardiographic (ECG) changes, elevated cardiac troponin levels, and regional wall motion abnormalities on echocardiogram. About 40% of patients with SAH demonstrate increased serum markers for myocardial necrosis. Approximately 10% of patients with SAH demonstrate left ventricular (LV) wall motion abnormalities; a subset of these patients will have irreversible myocardial damage, but most regain LV function in several weeks. Cardiac effects of SAH are thought to be a result of an imbalance of the autonomic nervous system with resultant increased catecholamine effect on the myocardial cells rather than due to preexisting coronary artery disease. These cardiovascular complications carry a prognostic significance in patients with SAH and can also be misdiagnosed as primary cardiac problems and delay the diagnosis of SAH. Herein, we present a case of a 68-year-old female who presented to the emergency department with acute onset of upper back and neck pain. She was initially misdiagnosed with myocardial infarction in view of the ischemic changes in the ECG and elevated cardiac troponins. She was started on antiplatelets and anticoagulation but was later found to have a negative coronary angiography and was diagnosed with SAH via a computed tomography (CT) scan. Intracranial hemorrhage can be associated with elevated cardiac enzymes and ECG changes and can sometimes masquerade as an acute coronary syndrome (ACS). A careful history and examination and a high index of clinical suspicion are pivotal in such cases since early diagnosis significantly impacts prognosis and prevents the inadvertent use of antiplatelets and anticoagulation, which can be detrimental if used in such cases.

ABSTRACT

BACKGROUND: Polycystic ovarian syndrome, a common endocrine disorder, is an important cause of infertility among women of reproductive age. Within the Gulf Cooperation Council countries, polycystic ovarian syndrome is found to affect women increasingly. No study has been carried out to critically summarize the evidence on the prevalence of polycystic ovarian syndrome among women suffering from infertility in these countries. OBJECTIVE: This protocol aims to conduct a systematic review and meta-analysis of the studies reporting the prevalence of polycystic ovarian syndrome among women seeking infertility treatment in the six Gulf Cooperation Council countries (Bahrain, Kuwait, Oman, Saudi Arabia, Qatar, and United Arab Emirates). DESIGN/METHODS AND ANALYSIS: The systematic review and meta-analysis will follow the following method. DATA SOURCE: Five databases, including PubMed, Embase, CINAHL, Web of Science, and SCOPUS, will be searched for observational studies using a combination of relevant keywords and Medical Subject Headings from inception of databases. DATA EXTRACTION: Two reviewers will screen titles and abstracts, followed by a full-text search based on the eligibility criteria. The main outcome is to measure the proportion of women who have polycystic ovarian syndrome among infertility-diagnosed patients. In addition, the risk of bias in the included studies will be assessed using the national institute of health quality assessment tool for observational studies. DATA SYNTHESIS: The random-effects method of the analysis with the inverse variance will be used to calculate the pooled prevalence of polycystic ovarian syndrome-attributed infertility. Variation in prevalence estimates will be calculated using subgroup analysis based on study and patients' characteristics and publication bias will be assessed via funnel plot inspection and Eggar's test. DISCUSSION: A critical assessment of evidence on the prevalence of polycystic ovarian syndrome in women attending fertility clinics is helpful in risk quantification, enabling better planning for managing infertility in women with polycystic ovarian syndrome. REGISTRATION: This protocol has been registered with PROSPERO, protocol registration number (CRD42022355087).
