Microphallus early management in infancy saves adulthood sensual life: A comprehensive review.

Microphallus/Micropenis is a rare condition with significant physical and psychological implications for affected individuals. This article comprehensively reviews micropenis, its etiology, epidemiology, and various treatment options. We conducted a thorough literature review to collect relevant information on micropenis and microphallus, as well as related disorders. Our primary databases were PubMed, Medline, and Google Scholar. We searched for articles published in English between 2000 and 2023. Our analysis included 67 review articles, 56 research studies, 11 case reports, one guideline, and one editorial. Our search terms included "microphallus", "micropenis", "congenital hypogonadotropic hypogonadism", "androgen insensitivity syndrome", "pediatric management of micropenis", "testosterone therapy", and "psychosocial implications of micropenis". We focused on diagnosing micropenis and related conditions, including hormonal assessments, medical and surgical treatment options, psychosocial and psychological well-being, sexual development of adolescents, and sociocultural influences on men's perceptions of penile size. Additionally, we explored parenting and family dynamics in cases of micropenis and disorders of sex development, implications of hormonal treatment in neonates, and studies related to penile augmentation procedures and their effectiveness. The article highlights the importance of early diagnosis and intervention in addressing the physical and psychological well-being of individuals with micropenis. Surgical procedures, such as penile lengthening and girth enhancement, and non-surgical approaches like hormonal therapy are explored. The significance of psychological support, education, and lifestyle modifications is emphasized. Early management and comprehensive care are crucial for individuals with micropenis, from infancy to adolescence and beyond. A multidisciplinary approach involving urologists, endocrinologists, and mental health professionals is recommended. Regular assessment of treatment effectiveness and the need for updated guidelines are essential to provide the best possible care. Healthcare professionals should prioritize early diagnosis, and neonatologists should measure stretched penile length in neonates. A collaborative effort is needed among professionals, parents, and affected individuals to create a supportive environment that recognizes worth beyond physical differences. Continuous research and evidence-based updates are crucial for improving care standards.

Synergistically active Fe3O4 magnetic and EDTA modified cellulose cotton fabric using chemical method and their effective pollutants removal ability from wastewater.

A unique combination of cotton fabric (CF) with a mixture of EDTA and APTES Fe3O4 magnetic particles was developed and utilized for the first time as an adsorbent for removing pollutants from wastewater. Initially, Fe3O4 was synthesized using the co-precipitation method. Further, the surface of Fe3O4 was modified by introducing amino functional groups through a reaction with APTES, resulting in Fe3O4-NH2. Following this, the surface of carbon fiber (CF) was altered using ethylenediaminetetraacetic acid (EDTA) to create CF@EDTA. Through the use of EDC-HCl and NHS, Fe3O4-NH2 was attached to the surface of CF@EDTA, resulting in the final product CF@EDTA/Fe3O4. Subsequently, the prepared CF@EDTA/Fe3O4 was utilized to adsorb metal pollutants from wastewater, with a thorough analysis conducted using various characterization techniques including FTIR, SEM, EDX, XRD, VSM, and XPS to study the materials. The study specifically aimed to assess the adsorption performance of our cotton-based material towards As(III) and Cr3+ metal ions. The pH study was also performed. Results indicated that the material exhibited an adsorption capacity of approximately 714 mg/g for As(III) ions and 708 mg/g for Cr3+ ions. The Langmuir and Freundlich models, as well as pseudo-first and second-order models were also analyzed. The Langmuir and pseudo-second-order models were found to best fit the data. In terms of regeneration and reusability, the materials showed straightforward regeneration and recyclability for up to 15 cycles. The remarkable adsorption capacity, combined with the unique blend of cotton and Fe3O4 magnet, along with its recyclability, positions our material CF@EDTA/Fe3O4 as a promising contender for wastewater treatment and other significant areas in water research.

Regenerative Endodontic Procedure on an Immature Necrotic Molar: A Case Report with a 5-Year Review.

BACKGROUND The regenerative endodontic procedure (REP) for managing necrotic immature permanent teeth has the advantage of promoting root growth over the traditionally used apexification techniques. However, there is limited evidence on the long-term outcome of standardized REPs performed on immature molars. This case report presents the 5-year clinical and radiographic outcomes of REP performed on an immature mandibular first molar. CASE REPORT A healthy 7-year-old girl with a carious right mandibular first molar was referred to the endodontic clinic for evaluation and treatment. Clinical examination showed large occlusal caries, no tenderness to palpation and percussion tests, and no response to cold and electric pulp tests. Radiographic examination showed deep caries, apical radiolucency related to the open apices, and wide root canal space. Accordingly, the tooth was diagnosed with necrotic pulp and asymptomatic apical periodontitis. The REP was performed following the American Association of Endodontics guidelines, which comprise minimal instrumentation, disinfection with sodium hypochlorite irrigant, use of triple antibiotic paste, induced intracanal bleeding, and application of a coronal mineral trioxide aggregate plug. The patient missed the scheduled follow-up appointments but presented at the clinic 5 years later with an asymptomatic tooth. Clinical and radiographic examination revealed no tenderness to percussion and palpation test, no response to cold test, positive response to electric pulp test, apical healing, apical closure, root lengthening, and canal wall thickening and calcification. CONCLUSIONS While true pulp regeneration is unachievable, the REP, following the current protocol, is clinically successful in achieving root maturation and tooth retention.

Spectrofluorometric determination of futibatinib in human plasma and pharmaceutical formulations.

Futibatinib is a powerful inhibitor of fibroblast growth factor receptors that impedes its phosphorylation and subsequently leading to a reduction in in cell viability across various cell lines. Futibatinib was approved for initial use as an effective treatment for several diseases, including non-small cell lung cancer and breast cancer. Herein, a novel selective fluorescence probe was created for futibatinib quantification in various matrices, including pharmaceutical formulation and human plasma. The technique primarily depends on futibatinib's chemical conversion into a fluorescent product through a reaction with trimethylamine and bromoacetyl bromide. The created fluorescent probe exhibits maximum emission peak at 338 nm upon excitation at 248 nm. The method provided a low detection limit of 0.120 ng/mL and maintained a linear concentration-dependent relationship across the range of 1-200 ng/mL. High sensitivity, accuracy and precision were demonstrated for futibatinib quantification in pharmaceutical formulation and spiked plasma matrix by the method, which was validated in accordance with ICH requirements.

Assessment of Health-Related Quality of Life Among Patients with Chronic Diseases and Its Relationship with Multimorbidity: A Cross-Sectional Study from Saudi Arabia.

Objective: Chronic diseases hold the potential to worsen the overall health of patients by limiting their functional status, productivity, and capacity to live well, affecting their overall health-related quality of life (HRQoL). The purpose of the study was to assess the HRQoL of individuals with chronic diseases residing in the Al-Jouf region of Saudi Arabia. Furthermore, the current study also sought to ascertain the impact of multimorbidity and the duration of illness on HRQoL. Material and Methods: A cross-sectional study was conducted among the residents of Al-Jouf region for a period of 6 months. A self-administered EuroQoL (EQ-5D-5L) study tool was used. Appropriate statistical analysis was conducted to ascertain the relationship between various variables and HRQoL. Results: A total of 500 out of 562 participants completed the study, with a response rate of 88.97%. Participants had a mean age of 46.15 ± 16.79 years, and the majority were female (n = 299; 59.80%). A mean HRQoL score of 0.82 ± 0.20 was reported, poorest in patients with kidney failure (0.65 ± 0.26) and highest in hepatitis. However, nearly half of the participants had diabetes mellitus type II (n = 205, 39.20%). Patients aged <30 years (OR: 0.109; p = 0.002), male participants (OR: 0.053; p < 0.001), no disability (OR: 0.143; p = 0.002), and <2 comorbid diseases (0.84 ± 0.18; p < 0.001) reported better QoL. Additionally, comorbid conditions such as DM, prolong the duration of the overall illness (14.19 ± 7.67 years). Overall, imperfect health (n = 390, 78%) was reported by the study participants. Conclusion: The present study provided preliminary data about the current HRQoL status of individuals with imperfect health and lower HRQoL. In the future, large-scale longitudinal studies are required to investigate the most prevalent chronic diseases, their associations, and change in HRQoL, as there is a dearth of information in the Saudi population.

Serological investigation of Coxiella burnetii infection (Query fever) in livestock in Makkah Province, Saudi Arabia.

Background and Aim: Query fever (Q fever) is an endemic zoonotic disease and ruminants are considered to be the primary source of infection in humans. It is caused by Coxiella burnetii which is an obligate intracellular bacterial pathogen with a worldwide distribution. This study estimated the prevalence of Q fever in livestock with a history of abortion in Makkah Province, Saudi Arabia. Material and Methods: Sera from 341 camels, 326 sheep, and 121 goats of either sex from various locations (Makkah, Jeddah, AL-Taif, AL-Qunfudah, AL-Laith, and AL-Kamil) were examined using a Q fever indirect enzyme-linked immunosorbent assay. Results: Among the 788 serum samples, 356 animals had anti-Coxiella burnetii immunoglobulin G antibodies with an overall seroprevalence of 45.4%. Significant differences were observed in seroprevalence between species and locations. Camels had the highest percentage of Q fever-positive sera, with a prevalence of 50.4%, followed by goats (44.6%) and sheep (36.8%), with a high significant difference between animals (p = 0.000). The prevalence was significantly higher in Makkah (65.4%) than in Jeddah (28.8%). Conclusion: C. burnetii infection is prevalent in agricultural animals, especially camels maintained at livestock farms in Makkah province. Therefore, these animals considered as the main source of Q fever infections in Saudi Arabia, which is also a reason for the abortion in these animals. Therefore, there is an urgent need for further studies on Q fever infection with interventional approaches for prevention and control.

Khat chewing among parents and their children: A potential transgenerational effect.

Background: Khat has a stimulating and addictive effect and can induce consequences on the health and socioeconomic status of khat chewers. Objectives: This study aims to assess knowledge, attitude, and practice of khat chewing among parents in Jazan and its consequential effect on their children. Methods: This cross-sectional investigation was conducted in the Jazan region of Saudi Arabia. Data was collected via a web-based, self-administered questionnaire measuring demographics, knowledge, attitudes, and practices concerning khat chewing. The Chi-square test or Fisher's exact test was used to assess factors associated with khat chewing among parents and its consequential effect on their children. Results: A total of 724 parents were included. The sample had an overall good knowledge about the health hazards of khat chewing and an attitude against khat chewing. Nonetheless, the number of parents who reported that they had ever tried khat chewing was 200 (27.6%) and 106 parents (14.6%) confirmed that their children were khat chewers. Additionally, 98 (13.5%) parents declared that they practiced khat chewing in front of their children. Higher frequencies of parents who reported providing khat to their children were identified among parents with higher attitude levels that favor khat chewing (P value = 0.04). Conclusions: Efforts should be made to develop targeted preventive and educational strategies to reduce khat chewing among parents who have favorable attitudes toward khat chewing.

A Rare Case of Adult Cervicothoracic Cystic Lymphangioma Presenting as Neurogenic Thoracic Outlet Syndrome.

Cystic lymphangioma (CL) is an uncommon congenital malformation of the lymphatic system, often occurring in the head, neck, or mediastinum, potentially causing compression symptoms like dysphagia or dyspnea, and in rare cases, neurogenic thoracic outlet syndrome (nTOS). This report details a case of a 38-year-old male with a four-year history of a left lower neck mass, experiencing tingling in his left forearm over the last six months. The examination revealed a left supraclavicular cystic mass, with imaging suggesting CL compressing neurovascular structures. The patient underwent successful complete surgical excision through a left supraclavicular approach. Histopathology confirmed CL, with no recurrence observed over 19 months. The case highlights that cervicothoracic CL with adult presentation can cause pressure symptoms including nTOS. It also underscores the role of a multimodal diagnostic approach to differentiate it from other neck masses and that a supraclavicular approach can effectively remove the cyst, especially when the lower extension is not deep and there is no surrounding inflammation, thereby leading to relieving pressure and preventing recurrence.

Restoration of gut dysbiosis through Clostridium butyricum and magnesium possibly balance blood glucose levels: an experimental study.

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by an elevated level of blood glucose due to the absence of insulin secretion, ineffectiveness, or lack of uptake of secreted insulin in the body. The improperly diagnosed and poorly managed DM can cause severe damage to organs in the body like the nerves, eyes, heart, and kidneys. This study was aimed at investigating the effect of Clostridium butyricum (probiotic) with magnesium supplementation to evaluate the effect on gut microbial dysbiosis and blood glucose levels. In the laboratory, 6-8 weeks old 24 male albino rats weighing 200-250 g were given free access to water and food. Diabetes was induced using streptozotocin (60 mg/kg) in overnight fasted rats. Diabetic rats were randomly divided into four groups (n = 6, 6 replicates in each group). Metformin (100 mg/kg/day) with a standard basal diet was provided to control group (G0), Clostridium butyricum (1.5 × 105 CFU/day) with standard basal diet was provided to treatment group (G1), magnesium (500 mg/kg/day) was provided to group (G2). Clostridium butyricum (1.5 × 105 CFU/day) and magnesium (300 mg/kg/day) in combination with a standard basal diet was provided to group (G3). Blood Glucose, Magnesium blood test and microbial assay were done. Random blood glucose levels were monitored twice a week for 21 days and were represented as mean of each week. The results conclude that Clostridium butyricum (1.5 × 105 CFU) is very effective in balancing random blood glucose levels from 206.6 ± 67.7 to 85.1 ± 3.8 (p = 0.006) compared to other groups (p > 0.005). The results of stool analysis showed that Clostridium butyricum as probiotic restores microbial dysbiosis as evident by the 105 CFU Clostridium butyricum load in G1, which was higher than G0, G2 and G3 which were 103 and 104 CFU respectively. The findings of this study conclude that Clostridium butyricum supplementation improved blood glucose levels and intestinal bacterial load in type II diabetes mellitus.

Enhanced Arabic disaster data classification using domain adaptation.

Natural disasters, like pandemics and earthquakes, are some of the main causes of distress and casualties. Governmental crisis management processes are crucial when dealing with these types of problems. Social media platforms are among the main sources of information regarding current events and public opinion. So, they have been used extensively to aid disaster detection and prevention efforts. Therefore, there is always a need for better automatic systems that can detect and classify disaster data of social media. In this work, we propose enhanced Arabic disaster data classification models. The suggested models utilize domain adaptation to provide state-of-the-art accuracy. We used a standard dataset of Arabic disaster data collected from Twitter for testing the proposed models. Experimental results show that the provided models significantly outperform the previous state-of-the-art results.

Spectrofluorometric determination of calcium in the human nasal secretions investigating the association with olfactory function.

Ionic microenvironment of the nasal secretions especially calcium ions play essential role in the olfactory transmission. However, there is a critical need to determine the free calcium levels in healthy people's nasal secretions in contrast to those of patients with olfactory impairment. A selective spectrofluorometric method was created to quantify nasal calcium levels utilizing its quenching ability to the fluorescence of the functionalized carbon quantum dots. The surface of carbon quantum dots was functionalized with calcium ionophore A23187 and ion association complex, calcium phosphotungstate, to improve the selectively to quantify calcium ions. The functionalized carbon quantum dots exhibited a concentration-dependent fluorescence quenching upon interaction with calcium ions. Different factors influencing the quenching process were done to provide efficient analytical process. The new method, demonstrated accurate calcium determination over the concentration range of 200-4000 ng/mL. The suggested technique was used to measure the calcium in the nasal secretions of both healthy people and patients with olfactory impairment. The findings revealed significantly higher calcium levels in the patient with olfactory dysfunction (healthy vs. patient; 735 ± 20 ng/mL vs. 2987 ± 37 ng/mL, p < 0.05).

Diagnostic value of IgG antibody and stool antigen tests for chronic Helicobacter pylori infections in Ibb Governorate, Yemen.

The stool antigen test (SAT) and the serum Helicobacter pylori (H. pylori) IgG antibody assays exhibit significant utility in the clinical diagnosis of H. pylori infection and in distinguishing between acute and chronic infections. The main objective of the current study was to identify the diagnostic value of serum H. pylori IgG antibody and SAT in the detection of H. pylori infections among chronic H. pylori-infected patients residing in Ibb Governorate, Yemen. 200 patients with H. pylori infection, confirmed through positive results in the serum immunochromatographic antibody test, were selected for H. pylori infection confirmation using serum H. pylori IgG antibodies and SAT across diverse hospitals, gastroenterology, and Hepatology clinics in Ibb Governorate. After the selection of patients, blood and stool specimens were obtained from all participants and underwent analysis via the Statistical Package for the Social Sciences (SPSS). The prevalence of H. pylori infection demonstrated variability based on the confirmatory tests, with rates of 54% for SAT and 78.5% for serum H. pylori IgG antibody, contrasting with a 100% prevalence observed in the screening serum immunochromatographic antibody test. Clinically, the study categorized H. pylori infections into four stages, whereby a significant proportion of patients (40.5%) exhibited positivity for both serum H. pylori IgG antibody and SAT, indicative of active chronic infections. The majority of positive cases only manifested serum H. pylori IgG antibody presence (chronic infections) at 38%, whereas 13.5% exclusively tested positive for SAT, corresponding to acute infections. Moreover, 88% of patients did not have either serum H. pylori IgG antibody or SAT (absence of infections) during confirmatory tests. Noteworthy is the study's approach employing multiple tests for H. pylori infection detection, focusing predominantly on chronic infections-prevailing types caused by H. pylori. The results revealed a significant association between serum levels of H. pylori IgG antibody and SAT results with the presence of diverse gastrointestinal symptoms among patients, which increased with long H. pylori infection durations.

A True Human Tail In A Neonate Born In Saudi Arabia: A Case Report.

A caudal cutaneous appendage known as the true human tail is a rare and benign condition. Different classification systems have been established, mostly based on the presence of associated spinal dysraphism. Imaging studies play an important role in detecting the prognosis and developing a management plan. Here, we present a rare case of a true human tail with no underlying spinal dysraphism in a preterm neonate.

Chitosan nanoparticles loaded with Foeniculum vulgare extract regulate retrieval of sensory and motor functions in mice.

In this study, chitosan nanoparticles (CSNPs) encapsulating Foeniculum vulgare (FV) seed extract (SE) were prepared for the controlled delivery of bioactive phytoconstituents. The prepared CSNPs encapsulating FVSE as sustain-releasing nanoconjugate (CSNPs-FVSE) was used as a potent source of functional metabolites including kaempferol and quercetin for accelerated reclamation of sensory and motor functions following peripheral nerve injury (PNI). The nanoconjugate exhibited in vitro a biphasic diffusion-controlled sustained release of quercetin and kaempferol ensuring prolonged therapeutic effects. The CSNPs-FVSE was administered through gavaging to albino mice daily at a dose rate of 25 mg/kg body weight from the day of induced PNI till the end of the experiment. The conjugate-treatment induced a significant acceleration in the regain of motor functioning, evaluated from the sciatic function index (SFI) and muscle grip strength studies. Further, the hotplate test confirmed a significantly faster recuperation of sensory functions in conjugate-treated group compared to control. An array of underlying biochemical pathways regulates the regeneration under well-optimized glucose and oxidant levels. Therefore, oxidant status (TOS), blood glycemic level and total antioxidant capacity (TAC) were evaluated in the conjugate-treated group and compared with the controls. The treated subjects exhibited controlled oxidative stress and regulated blood sugars compared to the non-treated control. Thus, the nanoconjugate enriched with polyphenolics significantly accelerated the regeneration and recovery of functions after nerve lesions. The biocompatible nanocarriers encapsulating the nontoxic natural bioactive constitutents have great medicinal and economic value.

Sampling Procedures for Estimating the Infant Intake of Human Milk Leptin, Adiponectin, Insulin, Glucose, and Total Lipid.

Limited attention is given to the efficacy of protocols for the estimation of infant intake of milk components when investigating their impact on infant outcomes. We compared the actual measured intake of human milk components with estimations derived from 15 protocols to determine the most reliable approach for estimating intake of HM leptin, adiponectin, insulin, glucose, and total lipid. Twenty mothers who were 3-5 months postpartum completed a 24 h milk profile study with pre-/post-feed milk samples collection. The true infant intake (control group) based on 24 h milk intake (MI) was compared to estimated infant intakes using concentrations from five sampling protocols that were multiplied by one of true infant MI, considered mean MI (800 mL), or global mean MI (766 mL). The mean measured concentrations of six samples (three sets of pre- and post-feed samples, from morning (06:00-09:00), afternoon (13:00-16:00), and evening (19:00-22:00)) multiplied by the true infant MI, mean considered MI, and global mean MI produced the most accurate estimates of infant intake of these components. Therefore, in the absence of 24 h measurements and sampling, a sampling protocol comprising three sets of pre-/post-feed samples provides the most reliable infant intake estimates of HM leptin, adiponectin, insulin, glucose, and total lipid.

Exploring the reported adverse effects of COVID-19 vaccines among vaccinated Arab populations: a multi-national survey study.

The coronavirus disease 2019 (COVID-19) pandemic has been a major challenge worldwide for the past years with high morbidity and mortality rates. While vaccination was the cornerstone to control the pandemic and disease spread, concerns regarding safety and adverse events (AEs) have been raised lately. A cross-sectional study was conducted between January 1st and January 22nd, 2022, in six Arabic countries namely Saudi Arabia, Egypt, Syria, Libya, Iraq, and Algeria. We utilized a self-administered questionnaire validated in Arabic which encompassed two main parts. The first was regarding sociodemographic data while the second was about COVID-19 vaccination history, types, doses, and experienced AEs. A multistage sampling was employed in each country, involving the random selection of three governorates from each country, followed by the selection of one urban area and one rural area from each governorate. We included the responses of 1564 participants. The most common AEs after the first and second doses were local AEs (67.9% and 46.6%, respectively) followed by bone pain and myalgia (37.6% and 31.8%, respectively). After the third dose, the most common AEs were local AEs (45.7%) and fever (32.4%). Johnson and Johnson, Sputnik Light, and Moderna vaccines showed the highest frequency of AEs. Factors associated with AEs after the first dose included an increase in age (aOR of 61-75 years compared to the 12-18 years group: 2.60, 95% CI: 1.59-4.25, p = 0.001) and male gender (OR: 0.72, 95% CI: 0.63-0.82, p < 0.001). The cumulative post-vaccination COVID-19 disease was reported with Sinovac (16.1%), Sinopharm (15.8%), and Johnson and Johnson (14.9) vaccines. History of pre-vaccination SARS-CoV-2 infection significantly increases the risk of post-vaccination COVID-19 after the first, second, and booster doses (OR: 3.09, CI: 1.9-5.07, p < 0.0001; OR: 2.56, CI: 1.89-3.47, p < 0.0001; and OR: 2.94, CI: 1.6-5.39, p = 0.0005 respectively). In conclusion, AEs were common among our participants, especially local AEs. Further extensive studies are needed to generate more generalizable data regarding the safety of different vaccines.

Time to FIRE NORSE: A single acronym for a heterogeneous presentation. Further information from a case series and discussion of the literature.

PURPOSE: New-Onset Refractory Status Epilepticus (NORSE) is a rare and severe form of refractory status epilepticus without an apparent underlying cause at presentation or prior history of epilepsy. We aimed to describe the clinical features, etiology, treatment, and outcomes of NORSE in adults in a quaternary-level hospital in Saudi Arabia. METHODOLOGY: In this retrospective cohort study, inclusion criteria involved patients over 14 years old who met the 2018 consensus definition for NORSE. Patients were identified using a combination of medical record admission labels 'status epilepticus' and 'encephalitis', and continuous EEG reports documenting status epilepticus. Demographic, clinical, and radiological data were collected and then analyzed for factors correlated with specific etiologies, better functional outcomes, and future diagnosis of epilepsy. RESULTS: We found 24 patients presenting with NORSE between 2010 and 2021. Fever/infectious symptoms were the most common prodrome. Elevated inflammatory serum and cerebrospinal fluid markers in most patients. Brain MRI revealed T2/FLAIR hyperintensity patterns, predominantly affecting limbic and perisylvian structures. The etiology of NORSE varied, with immune-related causes being the most common. Long-term outcomes were poor, with a high mortality rate and most survivors developing drug-resistant epilepsy. CONCLUSION: This study provides valuable insights into NORSE's clinical characteristics, highlighting the heterogeneity of this condition. The poor outcome is likely related to the progressive nature of the underlying disease, where refractory seizures are a clinical symptom. Thus, we propose to focus future research on the etiology rather than the NORSE acronym.

Non-enzymatic paper-based analytical device for direct potentiometric detection of urine creatinine.

A paper-based analytical device (PAD) with an integrated composite electrode has been designed and fabricated for non-enzymatic creatinine sensing. Reduced graphene oxide (rGO) was employed to modify the PAD so that it could function as a solid-contact transducer. A new macrocyclic pyrido-hexapeptide derivative was made and used as a special ionophore in the creatinine membrane sensor. The synthesized PAD showed a detection limit of 1.0 µM (S/N = 3) and a potentiometric response towards creatinine throughout a log-linear range of 2.0 µM-10 mM (R2 = 0.9998). The sensor shows significant selectivity for a few related substances, including ephedrine, codeine, ketamine, caffeine, urea, urate, carbinoxamine, and dextromethorphan. It has been established that the testing method is appropriate for the direct potentiometric detection of creatinine in a variety of human urine sample types. When an indicating electrode and a reference electrode are put on the same flexible disposable, this lets applications with a small sample volume be done. For point-of-care creatinine measurement, the developed paper-based analytical equipment is a good choice because it is affordable, easily accessible, and self-pumping (especially when combined with potentiometric detection).

Awareness of Risk Factors for Coronary Artery Disease in the Population of Al-Majma'ah Region, Saudi Arabia.

BACKGROUND: Coronary artery disease (CAD) is a significant global health concern and a leading cause of morbidity and mortality. As a complex cardiovascular condition, CAD arises from the accumulation of atherosclerotic plaques within the coronary arteries, leading to restricted blood flow to the heart muscle. While CAD has been extensively studied, its prevalence remains a challenge, particularly in diverse populations with distinct cultural and lifestyle practices. OBJECTIVES:  To assess the awareness of risk factors for CAD in the population of Al-Majma'ah Region, Saudi Arabia. METHODS:  The purpose of this cross-sectional descriptive study was to determine participants' awareness of CAD risk factors among the population of Al-Majma'ah Region, Saudi Arabia. It was conducted by the use of a self-administered questionnaire that had been validated in prior research publications. Sociodemographic information as well as the prevalence of cardiovascular disease risk factors were covered in the survey. The data analysis was done using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). RESULTS: A total of 919 individuals were enrolled in the current study after meeting the inclusion criteria. The results showed that most of the respondents 626 (68.1%) had a good level of awareness, 261 (28.4%) had a fair level of awareness, while only 32 (3.5%) of the respondents had a poor level of CAD risk factors awareness. CONCLUSION: The majority of participants had a good level of knowledge regarding CAD risk factors. The correlation between monthly income and awareness of coronary artery risk factors was statistically significant.

Consanguineous marriages increase the incidence of recurrent tuberculosis: Evidence from whole exome sequencing.

BACKGROUND: In this study, we have identified multiple mutations in the IL-12R1 gene among Pakistani patients who have inherited them through consanguineous marriages. These patients have experienced severe Bacille-Calmette-Guérin (BCG) infection as well as recurrent tuberculosis. We will demonstrate the pivotal role of interleukin (IL)-12/interferon (IFN)-γ axis in the regulation of mycobacterial diseases. METHODOLOGY: First, we checked the patients' medical records, and then afterward, we assessed interferon-gamma (IFN-γ) production through ELISA. Following that, DNA was extracted to investigate IL-12/IFN- abnormalities. Whole exome sequencing was conducted through Sanger sequencing. Secretory cytokine levels were compared from healthy control of the same age groups and they were found to be considerably less in the disease cohort. To evaluate the probable functional impact of these alterations, an in silico study was performed. RESULTS: The study found that the patients' PBMCs produced considerably less IFN-γ than expected. Analysis using flow cytometry showed that activated T cells lacked surface expression of IL-12Rß1. Exon 7 of the IL-12Rß1 gene, which encodes a portion of the cytokine binding region (CBR), and exon 10, which encodes the fibronectin-type III (FNIII) domain, were found to have the mutations c.641 A > G; p.Q214R and c.1094 T > C; p.M365T, respectively. In silico analysis showed that these mutations likely to have a deleterious effect on protein function. CONCLUSION: Our findings indicate the significant contribution of the IL-12/IFN-γ is in combating infections due to mycobacterium. Among Pakistani patients born to consanguineous marriages, the identified mutations in the IL-12Rß-1 gene provide insights into the genetic basis of severe BCG infections and recurrent tuberculosis. The study highlights the potential utility of newborn screening in regions with mandatory BCG vaccination, enabling early detection and intervention for primary immunodeficiencies associated with mycobacterial infections. Moreover, the study suggests at the potential role of other related genes such as IL-23Rß1, TYK2, or JAK2 in IFN-γ production, warranting further investigation.
