ABSTRACT

OBJECTIVES: To study the prevalence of tumor marker (TM) carcinoembryonic antigen (CEA), cancer antigen 125 (CA 125), and cancer antigen 15-3 (CA 15-3) levels in the Saudi population, based on gender, age, and demographic region, and whether the patients were referred by a hospital or self-referred.

METHODS: Retrospective analysis was carried out on 7,019 samples gathered from the Western, Northern, Central, Southern, and Eastern regions of Saudi Arabia between 2021-2022. The TMs were categorized into normal and abnormal levels, according to the reference ranges. Statistical analysis was carried out to assess the relations between variants (age groups, gender, and demographic regions) using the Chi-square test, and their correlations were assessed using Spearman’s test.

RESULTS: Among all patients, CEA, CA 125, and CA 15-3 levels were found to be significantly correlated with age (p=0.0001). The CEA and CA 15-3 levels increased in both males and females with age. The CA 125 was shown to have an abnormally increased level in males with age.

CONCLUSION: Increased levels of CEA, CA 125, and CA 15-3 TMs in the study population were significantly correlated with age. The CEA and CA 15-3 levels were within the normal range, while CA 125 levels were above the normal range in the older male population. These results suggest that the utilization of such TMs is age dependent and would have validity if applied with other parameters.

ABSTRACT

OBJECTIVES: To assess the risk variables related to the types of candidemia for each patient, who was admitted into the intensive care unit regardless of the patient with or without complete diagnosis of COVID-19, during the period of March 2019 to December 2022.

METHODS: The evaluation comparison of demographic and clinical data of COVID-19 positive and negative patients with candidemia confirmed in blood, 113 cases were assessed. Variables such as gender, age, age of hospitalization, history of hospitalization, concurrently infection, The acute physiology and chronic health evaluation-II scores, comorbidity checking, intubation, central venous catheter use, parenteral nutrition use, steroid use, antibiotic use, lymphopenia, and laboratory variables were evaluated. Candida species distribution, antifungal susceptibility in blood culture were determined.

RESULTS: Coronavirus disease-19 was present in 62.8% of cases confirmed candidemia, and these cases were significantly different from COVID-19 negative cases. Significance was found in more intubation, central venous catheter use, parenteral nutrition, and steroid therapy in Group 2. There was no significance with species distribution and associated infection. In total, COVID-19 positive had higher hemoglobin, aspartate aminotransferase, alanine transaminase, and white blood cell levels, which may be associated with the possibility of revealing and controlling candidemia.

CONCLUSION: Candida albicans and Candida Parapsilosis (C. parapsilosis) are the species seen in infected COVID-19 patients, while C. parapsilosis and Candida tropicalis are found in non-COVID-19 ones. Risk factors were intubation, parenteral nutrition, central venous catheter, and steroid in the COVID-19 group.

ABSTRACT

OBJECTIVES: To assess the prevalence of various frontal sinus fractures (FSF) and examine the relationships between these fractures, types of treatments, and potential complications.

METHODS: A retrospective study was carried out in King Saud Medical City, Riyadh, Saudi Arabia. The study analyzed the records of patients who were diagnosed and treated with FSF from 2011-2021. Files with missing documents or incomplete treatment were excluded. The retrieved data includes: patients age, gender, types, locations, treatment, and complications of FSF. Data was analyzed by the statistical Package for the Social Sciences Statistics, version 23.0 using descriptive statistics and Chi-square test.

RESULTS: A total of 72 cases were included, 94.4% males and 5.6% females. Road traffic accidents were the common cause of trauma (91%). Frontal sinus fractures were unilateral in 59.7% and associated other injuries in 80.6% of cases. Anterior table fractures were the largest proportion (58.3%), followed by anterior and posterior table (37.5%). The carried out surgical procedures were obliteration (23.9%), cranialization and obliteration (23.9%), and fixation only (52.2%). The post-operative complications were categorized into; neurological (22.2%), ophthalmic (15.3%), infection (2.8%), and deformity (16.7%). Anterior and posterior table had the highest percentage among these categories.

CONCLUSION: Frontal sinus fractures were mostly required surgical treatment (63.9%) and post-operative complications occurred especially the neurological and ophthalmic. We recommend studies on the association of complications and different types of obliteration materials.

ABSTRACT

OBJECTIVES: To analyze the relationship between chronically ill patients’ behaviors in acquiring and verifying health information from a digital environment with health literacy and patient empowerment using a structural equation modeling approach.

METHODS: This study was carried out in a public hospital in Turkey between February and May 2023. The study consisted of 365 participants and used descriptive and correlation-based designs for statistical analyses. It also executed computations for descriptive statistics and correlations to carry out a path analysis to assess model fitness and to identify direct and indirect effects.

RESULTS: This study identified that Web 1.0 and health information acquisition and digital verification variables statistically and significantly affected access to information, understanding information, appraisal (valuing)/evaluation, and application/use variables. The study also found that access to information variables was statistically significant on identity/identicalness, self-control, decision-making, and recognition and comprehension. The tested model fit the data well and adequately explained the direct effects of the variables.

CONCLUSION: The study concluded by suggestively improving the chronically ill patients’ media or digital literacy levels through special training to stimulate their internet use effectively.

ABSTRACT

OBJECTIVES: External beam radiation with sensitizing platinum is the recommended therapy for locally advanced vulvar cancers not amenable to curative surgery and is associated with considerable acute and chronic side effects. Radical vulvectomy post-radiation for persistent disease is often compromised with poor wound healing. We describe clinical outcomes for patients who received neoadjuvant chemotherapy plus bevacizumab followed by radical vulvectomy for locally advanced vulvar cancer.

METHODS: We performed retrospective analyses of all patients at our institution who underwent radical vulvectomy from January 2015 to November 2023. Of 113 patients, 13 patients underwent neoadjuvant chemotherapy. Demographics and clinicopathologic data were extracted, and descriptive statistical analyses were performed. Cases with neoadjuvant chemotherapy plus bevacizumab were further evaluated for response, adverse effects, and survival.

RESULTS: Neoadjuvant chemotherapy was administered to 13 patients with stage II-IV disease that involved the urethra, vagina, or anus. Lesion sizes ranged from 4 to 20 cm (median 7 cm). Patients received 2-6 cycles of carboplatin or cisplatin, paclitaxel, and bevacizumab. Nine (69.2%) patients had partial pathologic responses, and four patients had complete responses. All patients had negative surgical margins. Ten (76.9%) patients had radiographic evidence of inguinal lymph node metastasis prior to neoadjuvant chemotherapy, and four had residual nodal disease. Only one patient developed a superficial groin seroma. Three patients developed recurrence, two locally and one distant, and there was one death. The median follow-up was 23 months (range 6-84 months).

CONCLUSIONS: Neoadjuvant chemotherapy using combination platinum/paclitaxel/bevacizumab was efficacious for locally advanced vulvar cancer, resulting in complete resections, negative margins, and excellent wound healing. A multi-institutional phase II trial is warranted to validate these findings.

ABSTRACT

BACKGROUND: As an initial treatment for primary membranous nephropathy (PMN), there remains a significant proportion of patients for whom rituximab is not fully effective. Here, we aimed to assess the effectiveness and safety of obinutuzumab as initial treatment in patients with PMN.

METHODS: In this observational case series, patients diagnosed with PMN and treated with obinutuzumab as initial treatment were included. Treatment response was assessed by 24-h urine total protein (24 h UTP) and serum albumin, and immunologic remission was assessed by phospholipase A2 receptor (PLA2R) antibodies.

RESULTS: Twelve patients with PMN receiving obinutuzumab as initial treatment were included. Over 6 months, a statistically significant reduction in 24 h UTP levels (p = 0.003) and an increase in serum albumin levels were observed (p < 0.001). By the 6-month follow-up, two patients (16.7%) achieved complete remission, eight (66.6%) reached partial remission, and two (16.7%) showed no remission. Immunological remission was observed in 44.4% of evaluable patients (n = 9) after 3 months, increasing to 100% (6/6) at 6 months. Except for cases 1, 2, and 3, the total B cell counts in the remaining patients fell to less than 5 cells/μL before the administration of the second dose of obinutuzumab, including seven patients with counts as low as 0 cells/μL. Mild to moderate treatment-related adverse events (TRAEs) were reported in 58.3% (7/12) of the patients. No serious TRAEs were reported.

CONCLUSIONS: Obinutuzumab demonstrates promising potential as an initial treatment for PMN, with good effectiveness and a manageable safety profile. Further large-scale prospective studies are needed to confirm these findings.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness of an educational stepwise robot-assisted radical prostatectomy (RARP) procedure for urology residents.

METHODS: We performed a detailed evaluation of 42 RARP procedures performed by a single urology resident from July 2019 to February 2022. The RARP procedures were divided into the following nine steps: (1) bladder dissection, (2) endopelvic fascia dissection, (3) bladder neck dissection, (4) seminal vesicle dissection, (5) Denonvilliers’ fascia dissection, (6) dorsal vascular complex ligation, (7) dissection of the prostatic apex, (8) posterior anastomosis, and (9) urethro-vesical anastomosis. The procedures were further subcategorized as anatomical understanding, spatial recognition, and technical skills for evaluation of resident training. The surgeries were divided into first and second halves, and patient characteristics and operative outcomes were statistically analyzed. The operative time of each of the nine steps and the reasons for proctor intervention were compared.

RESULTS: Among 42 patients, there were no significant differences in operative outcomes between the two groups. The median operative time was 169 min (164 vs. 179 min, p = .12), and the median console time was 128 min (127 vs. 130 min, p = .74). Although there were no significant differences in the time of the nine steps, the resident significantly overcame (7) dissection of the prostatic apex and (8) posterior anastomosis based on the evaluation of the proctored reasons for intervention.

CONCLUSIONS: Urology residents can safely perform and efficiently learn RARP with this stepwise educational system. This educational stepwise RARP procedure can effectively help residents to develop their skills.

ABSTRACT

AIMS: Early clinical studies have indicated that the pharmacokinetics of Atuliflapon (AZD5718) are time and dose dependent. The reason(s) for these findings is(are) not fully understood, but pre-clinical profiling suggests that time-dependent CYP3A4 inhibition cannot be excluded. In clinical practice, Atuliflapon will be co-administered with CYP3A4 substrates; thus, it is important to determine the impact of Atuliflapon on the pharmacokinetics (PK) of CYP3A4 substrates. The aim of this study was to evaluate the effect of Atuliflapon on the pharmacokinetics of a sensitive CYP3A4 substrate, midazolam, and to explore if the time-/dose-dependent effect seen after repeated dosing could be an effect of change in CYP3A4 activity.

METHODS: Open-label, fixed-sequence study in healthy volunteers to assess the PK of midazolam alone and in combination with Atuliflapon. Fourteen healthy male subjects received single oral dose of midazolam 2 mg on days 1 and 7 and single oral doses of Atuliflapon (125 mg) from days 2 to 7. A physiologically based pharmacokinetic (PBPK) model was developed to assess this drug-drug interaction.

RESULTS: Mean midazolam values of maximum plasma concentration (C_max) and area under the curve (AUC) to infinity were increased by 39% and 56%, respectively, when co-administered with Atuliflapon vs. midazolam alone. The PBPK model predicted a 27% and 44% increase in AUC and a 23% and 35% increase in C_max of midazolam following its co-administrations with two predicted therapeutically relevant doses of Atuliflapon.

CONCLUSIONS: Atuliflapon is a weak inhibitor of CYP3A4; this was confirmed by the validated PBPK model. This weak inhibition is predicted to have a minor PK effect on CYP3A4 metabolized drugs.

ABSTRACT

Given the high and growing prevalence of obesity among adults in the United States, obesity treatment and prevention are important topics in biomedical and public health research. Although researchers recognize the significance of this problem, much remains unknown about safe and effective prevention and treatment of obesity in adults. In response to the worsening obesity epidemic and the many unknowns regarding the disease, a group of key scientific and program staff members of the National Institutes of Health (NIH) and other federal and non-government agencies gathered virtually in September 2021 to discuss the current state of obesity research, research gaps, and opportunities for future research in adult obesity prevention and treatment. The current article synthesizes presentations given by attendees and shares their organizations’ current initiatives and identified gaps and opportunities. By integrating the information discussed in the meeting and current initiatives, we identify potential targets and overlapping priorities for future research, including health equity and disparities in obesity, the heterogeneity of obesity, and the use of technological and innovative approaches in interventions.

ABSTRACT

BACKGROUND: Recent randomized clinical trials and meta-analyses confirm that the use of a prophylactic mesh doesn’t significantly reduce the parastomal hernia rate. Data about the benefits of these meshes concerning the symptoms of the parastomal hernia lack in the existing literature.

OBJECTIVE: The aim of this study was to perform a post-hoc analysis of the patients presenting parastomal hernia from the GRECCAR 7 randomized clinical trials cohort on whether the presence or absence of the mesh influenced the symptoms, the quality of life and complications of patients with parastomal hernias.

DESIGN: We studied the parastomal hernia related symptoms among the two groups of the GRECCAR 7 randomized clinical trial, with or without prophylactic mesh at the time of the index surgery.

SETTINGS: Data were retrospectively extracted and analyzed from the GRECCAR 7 database.

PATIENTS: Patients diagnosed with a parastomal hernia during the two years of the GRECCAR 7 study.

MAIN OUTCOME MEASURES: Several prospectively collected data about the symptoms were studied among this population. We also studied the average interval between parastomal hernia repair surgery and both index surgery and diagnosis of parastomal hernia.

RESULTS: Among the 199 patients included in the GRECCAR study, 36 patients (35.6%) were diagnosed with clinical and/or radiological parastomal hernia in the non-mesh group at 2 years follow-up and 33 (33.7%) in the mesh group, without statistically significant difference (p = 0.89). None of the studied symptoms showed any statistically significant difference between the groups.

LIMITATIONS: This study relies on a relatively small number of patients, and although data were prospectively collected, we lacked some details about the categorization of the parastomal hernias.

CONCLUSIONS: We believe that the use of a prosthetic mesh in a sublay position to prevent parastomal hernia in terminal end colostomy patients should no longer be recommended. See Video Abstract.
