Effects of novel GLT-1 modulator, MC-100093, on neuroinflammatory and neurotrophic biomarkers in mesocorticolimbic brain regions of male alcohol preferring rats exposed chronically to ethanol.

Chronic ethanol consumption can lead to increased extracellular glutamate concentrations in key reward brain regions, such as medial prefrontal cortex (mPFC) and nucleus accumbens (NAc), and consequently leading to oxidative stress and neuroinflammation. Previous studies from our lab tested ß-lactam antibiotics and novel beta-lactam non-antibiotic, MC-100093, and showed these ß-lactam upregulated the major astrocytic glutamate transporter, GLT-1, and consequently reduced ethanol intake and normalized glutamate homeostasis. This present study tested the effects of novel synthetic ß-lactam non-antibiotic drug, MC-100093, in chronic ethanol intake and neuroinflammatory and trophic factors in subregions of the NAc (NAc core and shell) and mPFC (Prelimbic, PL; and Infralimbic, IL) of male P rats. MC-100093 treatment reduced ethanol intake after 5-week drinking regimen. Importantly, MC-100093 attenuated ethanol-induced downregulation of brain derived neurotrophic factor (BDNF) expression in these brain regions. In addition, MC-100093 attenuated ethanol-induced upregulation of pro-inflammatory cytokines such as TNF-a and HMGB1 in all these brain regions. Furthermore, MC-100093 treatment attenuated ethanol-induced increase in RAGE in these brain regions. MC-100093 prevented neuroinflammation caused by ethanol intake as well as increased neurotrophic factor in mesocorticolimbic brain regions. MC-100093 treatment reduced ethanol intake and this behavioral effect was associated with attenuation of reduced trophic factors and increased pro-inflammatory factors. MC-100093 is considered a small molecule that may have potential therapeutic effects for the treatment of the effects of chronic exposure to ethanol.

Flexible 3D Force Sensor Based on Polymer Nanocomposite for Soft Robotics and Medical Applications.

The three-dimensional (3D) force sensor has become essential in industrial and medical applications. The existing conventional 3D force sensors quantify the three-direction force components at a point of interest or extended contact area. However, they are typically made of rigid, complex structures and expensive materials, making them hard to implement in different soft or fixable industrial and medical applications. In this work, a new flexible 3D force sensor based on polymer nanocomposite (PNC) sensing elements was proposed and tested for its sensitivity to forces in the 3D space. Multi-walled carbon nanotube/polyvinylidene fluoride (MWCNT/PVDF) sensing element films were fabricated using the spray coating technique. The MWCNTs play an essential role in strain sensitivity in the sensing elements. They have been utilized for internal strain measurements of the fixable 3D force sensor's structure in response to 3D forces. The MWCNT/PVDF was selected for its high sensitivity and capability to measure high and low-frequency forces. Four sensing elements were distributed into a cross-beam structure configuration, the most typically used solid 3D force sensor. Then, the sensing elements were inserted between two silicone rubber layers to enhance the sensor's flexibility. The developed sensor was tested under different static and dynamic loading scenarios and exhibited excellent sensitivity and ability to distinguish between tension and compression force directions. The proposed sensor can be implemented in vast applications, including soft robotics and prostheses' internal forces of patients with limb amputations.

Impact of COVID-19 pandemic on transplant laboratories: How to mitigate?

A positive flow cytometry crossmatch (FCXM) due to donor specific antibodies (DSA) constitutes a risk for kidney transplantation; such a finding may indicates an unacceptable donor for this patient. However, positive FCXM in the absence of DSA is considered discordant and need further investigations. During COVID-19 pandemic, we observed 22% discordant results out of 445 FCXM performed during eight months period in our laboratory and another 7% were invalid due to high background negative control (NC). No study has addressed the impact of COVID-19 pandemic on FCXM and the overall pre-kidney transplant workups or described a solution to deal with these non-specific reactivities. Herein, we analyzed all FCXM results in SARS-CoV-2 seropositive patients and addressed how this pandemic affected significantly the pre-kidney transplant workups, highlighting both technical and financial implications. We also shared our modified FCXM procedures using dithiotheritol (DTT) sera treatment or blocking donor cells with negative control human serum (NCS) which we found to be successful to abrogate 98% of all discordant FCXM results and to validate all invalid results due to high background NC. In conclusion, COVID-19 pandemic has affected our HLA laboratory significantly by creating many false positive or invalid crossmatch results. Transplant laboratories must consider this before test interpretations and immune risk assessments. We recommend the use of DTT serum treatment to remove nonspecific bindings in the sera of kidney transplant candidates and the use of NCS-blocked donor cells to correct high background when performing FCXM in transplant candidates or donors with recent history of SARS-CoV-2 immunization respectively.

Awareness of Diabetic Patients in the Qassim Region About Diabetic Foot and Its Complications.

Introduction Diabetes mellitus (DM) is a chronic condition brought on by either insufficient insulin production by the pancreas or inefficient insulin utilization by the body. A hormone called insulin controls blood sugar. Patients with type 1 or type 2 diabetes frequently experience diabetes complications, which are also a major cause of morbidity and mortality. Microvascular and macrovascular problems of diabetes are the two main categories, with the former having a significantly higher prevalence than the latter. In contrast to macrovascular problems, which include cardiovascular disease, stroke, and peripheral artery disease (PAD), microvascular sequelae include neuropathy, nephropathy, and retinopathy. The occurrence of a foot ulcer coupled with neuropathy, PAD, and infection is known as diabetic foot (DF) syndrome, and it is a primary factor in lower limb amputation. Finally, there are additional diabetes problems that fall outside of the two categories listed before, including birth defects, dental disease, and decreased infection resistance. Aim This study aimed to evaluate the awareness of diabetic patients in the Qassim region about diabetic foot and its complications. Patient and methods This retrospective cohort study was conducted between January 2021 and January 2022 among diabetic patients. The patients were contacted through the contact numbers listed in their medical charts at the Diabetic Center in King Saud Hospital in Unaizah and the Diabetes Center in King Fahad Specialist Hospital. The data were collected by sending the link to the targeted patients using the Google Form questionnaire. Results Of the 384 diabetic patients, 51.6% were females, and 28.6% were aged between 18 and 30 years old. A previous history of foot ulcers has been reported by 10.4%. The overall mean score was 11.3 (SD 2.99) out of 20 points, with poor, moderate, and good awareness levels constituting 25.8%, 66.4%, and 7.8%, respectively. Factors associated with increased awareness include younger age, female gender, having no associated chronic disease, and not experiencing soreness on the foot or leg. Conclusion There was modest awareness among the diabetic population regarding diabetes foot care and its complications. Independent significant predictors of increased knowledge include younger age, female gender, having no associated chronic disease, and not experiencing soreness on the foot or leg. Increased diabetic education is vital to improving awareness levels of diabetic foot complications.

External validation of the Manchester Acute Coronary Syndromes ECG risk model within a pre-hospital setting.

OBJECTIVES: The Manchester Acute Coronary Syndromes ECG (MACS-ECG) prediction model calculates a score based on objective ECG measurements to give the probability of a non-ST elevation myocardial infarction (NSTEMI). The model showed good performance in the emergency department (ED), but its accuracy in the pre-hospital setting is unknown. We aimed to externally validate MACS-ECG in the pre-hospital environment. METHODS: We undertook a secondary analysis from the Pre-hospital Evaluation of Sensitive Troponin (PRESTO) study, a multi-centre prospective study to validate decision aids in the pre-hospital setting (26 February 2019 to 23 March 2020). Patients with chest pain where the treating paramedic suspected acute coronary syndrome were included. Paramedics collected demographic and historical data and interpreted ECGs contemporaneously (as 'normal' or 'abnormal'). After completing recruitment, we analysed ECGs to calculate the MACS-ECG score, using both a pre-defined threshold and a novel threshold that optimises sensitivity to differentiate AMI from non-AMI. This was compared with subjective ECG interpretation by paramedics. The diagnosis of AMI was adjudicated by two investigators based on serial troponin testing in hospital. RESULTS: Of 691 participants, 87 had type 1 AMI and 687 had complete data for paramedic ECG interpretation. The MACS-ECG model had a C-index of 0.68 (95% CI: 0.61 to 0.75). At the pre-determined cut-off, MACS-ECG had 2.3% (95% CI: 0.3% to 8.1%) sensitivity, 99.5% (95% CI: 98.6% to 99.9%) specificity, 40.0% (95% CI: 10.2% to 79.3%) positive predictive value (PPV) and 87.6% (87.3% to 88.0%) negative predictive value (NPV). At the optimal threshold for sensitivity, MACS-ECG had 50.6% sensitivity (39.6% to 61.5%), 83.1% specificity (79.9% to 86.0%), 30.1% PPV (24.7% to 36.2%) and 92.1% NPV (90.4% to 93.5%). In comparison, paramedics had a sensitivity of 71.3% (95% CI: 60.8% to 80.5%) with 53.8% (95% CI: 53.8% to 61.8%) specificity, 19.7% (17.2% to 22.45%) PPV and 93.3% (90.8% to 95.1%) NPV. CONCLUSION: Neither MACS-ECG nor paramedic ECG interpretation had a sufficiently high PPV or NPV to 'rule in' or 'rule out' NSTEMI alone.

Towards exploring current challenges and future opportunities relating to the prehospital triage of patients with traumatic brain injury: a mixed-methods study protocol.

INTRODUCTION: Traumatic brain injury (TBI) is a major global health burden that results in disability and loss of health. Identifying those patients who require specialist neuroscience care can be challenging due to the low accuracy of existing prehospital trauma triage tools. Despite the widespread use of decision aids to 'rule out' TBI in hospitals, they are not widely used in the prehospital environment. We aim to provide a snapshot of current prehospital practices in the UK, and to explore facilitators and challenges that may be encountered when adopting new tools for decision support. METHODS AND ANALYSIS: A mixed-methods study will be conducted using a convergent design approach. In the first phase, we will conduct a national survey of current practice in which every participating ambulance service in the UK will receive an online questionnaire, and only one response is required. In the second phase, semistructured interviews will be conducted to explore the perceptions of ambulance service personnel regarding the implementation of new triage methods that may enhance triage decisions. The survey questions and the interview topic guide were piloted and externally reviewed. Quantitative data will be summarised using descriptive statistics; qualitative data will be analysed thematically. ETHICS AND DISSEMINATION: This study has been approved by the Health Research Authority (REC reference 22/HRA/2035). Our findings may inform the design of future care pathways and research as well as identify challenges and opportunities for future development of prehospital triage tools for patients with suspected TBI. Our findings will be published in peer-reviewed journals, relevant national and international conferences, and will be included in a PhD thesis.

Formulation of Multicomponent Chrysin-Hydroxy Propyl ß Cyclodextrin-Poloxamer Inclusion Complex Using Spray Dry Method: Physicochemical Characterization to Cell Viability Assessment.

The work aimed to enhance chrysin (CHR) water solubility, dissolution, and in vitro antibacterial as well as cell viability. Chrysin binary, as well as ternary inclusion complex, were prepared using the spray drying method. The influence of an auxiliary component (poloxamer; PLX) was also assessed after being incorporated into the chrysin HP ßCD complex (CHR-BC) and formed as a chrysin ternary complex (CHR-TC). The phase solubility investigation was carried out in order to assess the complexation efficiency and stability constant. The samples were assessed for the dissolution test, physicochemical evaluation, antibacterial activity, and cell viability tests were also assessed. The results of the phase solubility investigation showed that the stability constant for the binary system (268 M-1) was lower than the ternary system (720 M-1). The complex stability was validated by the greater stability constant value. The dissolution results showed that pure CHR had a limited release of 32.55 ± 1.7% in 60 min, while prepared CHR-TC and CHR-BC both demonstrated maximum CHR releases of 99.03 ± 2.34% and 71.95 ±2.1%, respectively. The dissolution study's findings revealed that the release of CHR was much improved over that of pure CHR. A study using a scanning electron microscope showed that CHR-TC contains more agglomerated and amorphous components. The higher conversion of crystalline CHR into an amorphous form is responsible for the structural alterations that are observed. After complexation, the distinctive peaks of pure CHR changed due to the complexation with HP ßCD and PLX. The antimicrobial and cell viability results revealed improved antimicrobial activity as well as a lower IC50 value than pure CHR against the tested anticancer cell line (MCF7).

National research guideline for prehospital emergency medical care: A prospective Delphi-study.

OBJECTIVES: To identify the most important research topics to establish a national research agenda and protocol for prehospital research in Saudi Arabia (KSA). METHODS: A 3-round modified Delphi consensus methods were used to determine high-priority research topics. Round I included an open-ended question to list all high-priority research topics in a prehospital setting in Riyadh, KSA. Rounds II and III included ranking evaluation and consensus agreement. The included topics were listed based on the agreement of ≥70% of the experts participating in the study. The study was carried out between November 2021 and February 2022. RESULTS: In total, 100 prehospital experts in KSA were invited to participate in all 3 rounds. Of these, 47 responded in round I, 34 in round II, and 39 in round III. In round I, participants submitted 278 research topics. After deduplication and sorting, 78 topics were assessed in the other 2 rounds. CONCLUSION: In this modified Delphi study, an expert panel identified the top prehospital emergency medical services (EMS) care research priorities. The leading research priorities included clinical and operational ideas. The proposed 32 high-priority topics can be used to guide researchers, research networks, policymakers, and funding organizations involved in EMS.

The diagnostic accuracy of prehospital triage tools in identifying patients with traumatic brain injury: A systematic review.

INTRODUCTION: Prehospital care providers are usually the first responders for patients with traumatic brain injury (TBI). Early identification of patients with TBI enables them to receive trauma centre care, which improves outcomes. Two recent systematic reviews concluded that prehospital triage tools for undifferentiated major trauma have low accuracy. However, neither review focused specifically on patients with suspected TBI. Therefore, we aimed to systematically review the existing evidence on the diagnostic performance of prehospital triage tools for patients with suspected TBI. METHODS: A comprehensive search of the current literature was conducted using Medline, EMBASE, CINAHL Plus and the Cochrane library (inception to 1st June 2021). We also searched Google Scholar, OpenGrey, pre-prints (MedRxiv) and dissertation databases. We included all studies published in English language evaluating the accuracy of prehospital triage tools for TBI. We assessed methodological quality and risk of bias using a modified Quality Assessment of Diagnostic Studies (QUADAS-2) tool. Two reviewers independently performed searches, screened titles and abstracts and undertook methodological quality assessments. Due to the heterogeneity in the population of interest and prehospital triage tools used, a narrative synthesis was undertaken. RESULTS: The initial search identified 1787 articles, of which 8 unique eligible studies met the inclusion criteria (5 retrospective, 2 prospective, 1 mixed). Overall, sensitivity of triage tools studied ranged from 19.8% to 87.9% for TBI identification. Specificity ranged from 41.4% to 94.4%. Two decision tools have been validated more than once: HITS-NS (2 studies, sensitivity 28.3-32.6%, specificity 89.1-94.4%) and the Field Triage Decision Scheme (4 studies, sensitivity 19.8-64.5%, specificity 77.4%-93.1%). Existing tools appear to systematically under-triage older patients. CONCLUSION: Further efforts are needed to improve and optimise prehospital triage tools. Consideration of additional predictors (e.g., biomarkers, clinical decision aids and paramedic judgement) may be required to improve diagnostic accuracy.

Towards enhanced telephone triage for chest pain: a Delphi study to define life-threatening conditions that must be identified.

BACKGROUND: Improving telephone triage for patients with chest pain has been identified as a national research priority. However, there is a lack of strong evidence to define the life-threatening conditions (LTCs) that telephone triage ought to identify. Therefore, we aimed to build consensus for the LTCs associated with chest pain that ought to be identified during telephone triage for emergency calls. METHODS: We conducted a Delphi study in three rounds. Twenty experts in pre-hospital care and emergency medicine experience from the UK were invited to participate. In round I, experts were asked to list all LTCs that would require priority 1, 2, and 4 ambulance responses. Round II was a ranking evaluation, and round III was a consensus round. Consensus level was predefined at > = 70%. RESULTS: A total of 15 participants responded to round one and 10 to rounds two and three. Of 185 conditions initially identified by the experts, 26 reached consensus in the final round. Ten conditions met consensus for requiring priority 1 response: oesophageal perforation/rupture; ST elevation myocardial infarction; non-ST elevation myocardial infarction with clinical compromise (defined, also by consensus, as oxygen saturation < 90%, heart rate < 40/min or systolic blood pressure < 90 mmHg); acute heart failure; cardiac tamponade; life-threatening asthma; cardiac arrest; tension pneumothorax and massive pulmonary embolism. An additional six conditions met consensus for priority 2 response, and three for priority 4 response. CONCLUSION: Using expert consensus, we have defined the LTCs that may present with chest pain, which ought to receive a high-priority ambulance response. This list of conditions can now form a composite primary outcome for future studies to derive and validate clinical prediction models that will optimise telephone triage for patients with a primary complaint of chest pain.

A systematic review of population-based gingival health studies among children and adolescents with autism spectrum disorder.

The prevalence of autism spectrum disorder (ASD) is close to 1% in the United States of America and other countries. Special attention should be given to oral health in individuals with ASD as they are often affected by oral diseases. However, gingival health in children with ASD and adolescents is controversial in terms of the severity of disease and number of people affected. AIM: To conduct a systematic review and meta-analysis to assess the gingival health status of children and adolescents with ASD. METHODS: The search was conducted using eight databases for articles that met the inclusion and exclusion criteria. This search produced 742 relevant papers, but only five with sufficient data on gingival and plaque indices were eligible for inclusion in this systematic review and meta-analysis. RESULTS: The homogeneity of the sample was tested using the Cohen Q test, which identified significant heterogeneity (P < 0.0001), indicating the use of the random effect's standard mean difference. Significantly higher gingival index and plaque index values were found in children and adolescents with ASD than in children without ASD. CONCLUSION: Individuals with ASD need help and better access to oral healthcare. Further investigation is needed with regard to gingival health in individuals with ASD and caries risk assessment to understand how this disorder affects oral health. A standardized index for gingival health will help in the inclusion of more studies to assess gingival health in children and adolescents with ASD.

Simultaneous Central Slip and Volar Plate Injuries at PIP Joint: A Novel Therapeutic Approach.

BACKGROUND: Central slip and volar plate injuries rarely occur in the same finger, with only two cases previously reported in published literature. In these two patients, both teenagers, two highly distinct protocols were used. Here, we report a third case involving a 51-year-old gentleman who closed a door on his left third finger. METHODS: Because the fractures were noncomminuted and only minimally displaced, he was treated nonsurgically using a multi-step process of splinting to prevent impairment of either proximal interphalangeal joint extension or flexion, combined with active range of motion exercises. This included five weeks of splinting in neutral, 24-hour daily use of a proximal interphalangeal dorsal block, followed by active range of motion exercises combined with nocturnal splinting using a PIP volar block over the next 7 weeks, with relative motion and Joint Jack splints added over the final 4 of these 7 weeks. RESULTS: Twelve weeks after initial splinting, the patient's finger was pain free, with swelling largely resolved, normal extension (-10 degrees) and near-normal flexion (95 degrees) achieved, and full function restored. The patient was very satisfied with the result. CONCLUSIONS: Ours is just the third case of concomitant central slip and volar plate injuries reported in the literature. Other surgeons are strongly encouraged to publish similar cases, approaches, and results, as clinical wisdom can sometimes be gleaned from even a small number of well-documented clinical cases.

The pedicled lateral forehead flap in reconstructing oral floor defect - The last resort; case report.

INTRODUCTION AND IMPORTANCE: Locoregional flaps, particularly the pedicled lateral forehead flap, are not usually used in reconstructing oral floor defects following oncologic resection. Rather, microscopic free flaps have evolved to be the standard of care in head and neck reconstruction. However, the pedicled lateral forehead flap could be valuable in floor of the mouth reconstruction in the absence of resources or other options. CASE PRESENTATION: A-56 years old lady with multiple comorbidities who underwent near total glossectomy, bilateral supraomohyoid neck dissection, and right lateral mandibulotomy due to a locally advanced lingual squamous carcinoma. The last resort was the pedicled lateral forehead flap after many unsuccessful reconstructive attempts utilizing the free anterolateral flap, free radial forearm flap, and pedicled pectoralis major flap. CLINICAL DISCUSSION: Decreased donor site morbidity and reliable anatomy are among many of the advantages that made free flaps favorable over locoregional pedicled flaps, especially in oral cavity defects coverage. Of the latter, the pedicled forehead flap, rich in vascularity and neighboring the oropharyngeal defects, could be used with different techniques and modifications. Close monitoring and patient condition optimization is required. CONCLUSION: Choosing a particular reconstructive option should be done considering the available resources and expertise and the patient's condition. The pedicled forehead flap remains valuable when other options are inappropriate or have failed.

Accuracy of emergency medical services (EMS) telephone triage in identifying acute coronary syndrome (ACS) for patients with chest pain: a systematic literature review.

OBJECTIVE: To systematically appraise the available evidence to determine the accuracy of decision aids for emergency medical services (EMS) telephone triage of patients with chest pain suspected to be caused by acute coronary syndrome (ACS) or life-threatening conditions. DESIGN: Systematic review. DATA SOURCES: Electronic searches were performed in Embase 1974, Medline 1946 and CINAHL 1937 databases from 3 March 2020 to 4 March 2020. ELIGIBILITY CRITERIA: The review included all types of original studies that included adult patients (>18 years) who called EMS with a primary complaint of chest pain and evaluated dispatch triage priority by telephone. Outcomes of interest were a final diagnosis of ACS, acute myocardial infarction or other life-threatening conditions. DATA EXTRACTION AND SYNTHESIS: Two authors independently extracted data on study design, population, study period, outcome and all data for assessment of accuracy, including cross-tabulation of triage priority against the outcomes of interest. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 assessment tool. RESULTS: Searches identified 553 papers, of which 3 were eligible for inclusion. Those reports described the evaluation of three different prediction models with variation in the variables used to detect ACS. The overall results showed that dispatch triage tools have good sensitivity to detect ACS and life-threatening conditions, even though they are used to triage signs and symptoms rather than diagnosing the patients. On the other hand, prediction models were built to detect ACS and life-threatening conditions, and therefore, prediction models showed better sensitivity and negative predictive value than dispatch triage tools. CONCLUSION: We have identified three prediction models for telephone triage of patients with chest pain. While they have been found to have greater accuracy than standard EMS dispatch systems, prospective external validation is essential before clinical use is considered. PROSPERO REGISTRATION NUMBER: This systematic review was pre-registered on the International prospective register of systematic reviews (PROSPERO) database (reference CRD42020171184).

Exploring satisfaction level among outpatients regarding pharmacy facilities and services in the Kingdom of Saudi Arabia; a large regional analysis.

BACKGROUND: Evaluation of patients`satisfaction towards pharmacy services is of utmost importance to ensure the quality of care. It helps in identifying domains requiring improvements to provide high quality pharmacy services to ensure the provision of enhanced pharmaceutical care. The current study aims to ascertain the extent of satisfaction towards pharmacy services among patients attending outpatient pharmacies in Kingdom of Saudi Arabia. METHODS: A hospital-based cross-sectional study involving 746 patients attending outpatient pharmacies of various public hospitals was conducted from 01 January to 15 February 2020. Information on socio-demographic profile of the study subjects along with their satisfaction towards outpatient pharmacy was extracted by using a 23-items questionnaire. These questions were divided into two domains including 7 questions related to the pharmacy facilities (questions from 1F to 7F) and 8 questions for pharmacy services (questions from 1S to 8S), where F and S denotes facilities and services, respectively. The cumulative satisfaction score was estimated by a 5-item Likert scale with a maximum score of 5 for each item. The relationship between demographics and satisfaction scores was evaluated by using appropriate statistics. RESULTS: There were 746 patients with male preponderance (58.8%). The overall satisfaction score was 2.97 ± 0.65. Satisfaction towards pharmacy services scored lower (mean score: 3.91 ± 0.77) than pharmacy facilities (mean score: 4.03 ± 0.66). Items related to patient`s counseling (3F, 2S, 3S, 6S) scored least during the analysis. Older patients (p = 0.006), male gender (p<0.001), Saudi nationality (0.035), patients attending primary care centers (p = 0.02), and patients with chronic illnesses were significantly associated with lower satisfaction score. CONCLUSION: This study reported that the satisfaction level of patients attending outpatient pharmacies was low and differed among various socio-demographic groups. Approximately one-half of the patients were not satisfied with outpatient pharmacy services. These findings underscore the dire need for managerial interventions including the hiring of trained professionals, onsite training of pharmacy staff, initiation of clinical or patient centered pharmacy services, evaluation of patient`s response towards the services and appropriate controlling measures, irrespective to the type of hospitals.

Demographic and Cultural Differences in the Acceptance and Pursuit of Cosmetic Surgery: A Systematic Literature Review.

Worldwide, the numbers of cosmetic procedures continue to climb. However, cosmetic surgery (CS) continues to be plagued by negative stigmatization. This study reviews the literature to identify how attitudes toward CS vary by sex, age, race, culture, and nationality, and aims to determine how other factors like media exposure interact with demographics to influence how well CS is accepted. METHODS: A PRISMA-guided systematic review of the literature was conducted to identify all English-language papers reporting on CS or plastic surgery acceptance, attitudes, or stigmatization, specifically examining for data on age, sex, race/ethnicity, culture, and media influence. RESULTS: In total, 1515 abstracts were reviewed, of which 94 were deemed pertinent enough to warrant a full-text review. Among the potential demographic predictors of CS acceptance, the one with the most supportive data is sex, with women comprising roughly 90% of all CS patients in virtually all populations studied and consistently exhibiting greater CS knowledge and acceptance. Culturally, the pursuit of beauty through CS is a universal phenomenon, although different countries, races, and cultures differ in how willingly CS is embraced, and in the aesthetic goals of those choosing to have it. In countries with culturally diverse societies like the United States, non-Hispanic Whites continue to predominate among CS patients, but the number of CS patients of other races is rising disproportionately. In this trend, social media is playing a major role. CONCLUSION: Healthcare practitioners performing cosmetic procedures need to consider demographic and cultural differences of the patients in order to enhance their understanding of their patients' aesthetic goals and expectations.

Gene Expression Profiling of Apoptotic Proteins in Circulating Peripheral Blood Mononuclear Cells in Type II Diabetes Mellitus and Modulation by Metformin.

INTRODUCTION: Insulin resistance in obesity and type 2 diabetes mellitus (T2DM) is associated with cardiovascular complications such as atherosclerosis. On the other hand, the reduction of apoptosis in macrophages has been linked with accelerated atherosclerosis. Apoptosis is controlled by a different family of proteins including Bcl-2 and caspases. METHODS: To examine apoptosis in insulin resistance, we assessed the mRNA expression by qRT-PCR of several Bcl-2 family members, as well as caspase-3, -7, -8, and -9 in peripheral blood mononuclear cells (PBMCs) isolated from lean, obese, diabetic, and diabetic on metformin individuals. RESULTS: PBMCs of diabetic individuals exhibited reduced expression of caspase-7 and increased expression of Bcl-10, Bad, Bax, Bid, and caspase-3. T2DM on metformin group had significantly higher Bad, Bax, and caspase-7 expression. DISCUSSION: The moderate up-regulation of pro-apoptotic Bcl-10, Bax, Bad, Bid, and the effector caspase-3 coupled with inhibition of caspase-7 in circulating PBMCs of T2DM could be the result of increased inflammation in T2DM. Metformin treatment significantly inhibited the expression of Bcl-10, Bid, and caspase-3 and upregulated Bad/Bax/caspase-7 pathway suggesting the activation of Bad/Bax/caspase-7 apoptotic pathway. Further studies are warranted to elicit the underlying apoptotic pathways of PBMCs in T2DM and following metformin treatment.

Impact of Drug Use Policy on the Appropriate Use of Direct Acting Antiviral Agents for Hepatitis C in Saudi Arabia.

BACKGROUND: Ministry of National Guard-Health Affairs in Saudi Arabia developed a new policy for the use of direct antiviral agents (DAAs) for hepatitis C. The present study was conducted to evaluate prescribers' compliance and the impact of the policy on DAAs appropriate use. MATERIALS AND METHODS: This study was conducted at King Abdul Aziz Medical City in Jeddah, Saudi Arabia. The study compares patients' data during 1 year before and 1 year after policy initiation. The primary outcomes were compliance to monitoring parameters, appropriateness of treatment and treatment eligibility. Secondary outcomes included sustained virologic response at 12 weeks, documentation of potential drug-drug interactions and treatment costs. Independent samples t-test and Chi-square test were used when applicable. A P < 0.05 was considered statistically significant. RESULTS: One hundred and three patients were included in analysis (46 before and 57 after policy). Prescriber compliance to baseline monitoring parameters was 67.4% before policy and 82.5% after-policy (P = 0.076). International normalized ratio (INR) was requested in 84.8% of cases before policy compared to 96.5% after-policy (P = 0.036). Treatment options offered to patients were appropriate in 52.2% of cases before policy and in 82.5% after-policy (P = 0.001). CONCLUSION: There is a significant improvement in the baseline monitoring of INR. Treatment options offered after policy implementation were significantly more appropriate.

Ketogenic Diets: Side Effects, Attitude, and Quality of Life.

INTRODUCTION: The ketogenic diet has been in use since the 1920s as a therapy for epilepsy. Since the 1960s, it has also become widely known as one of the methods for obesity treatment. Recently, this diet has been promoted as a lifestyle, making it highly controversial in terms of its practicality as a lifestyle diet and its duration without affecting one's health or quality of life. Hence, this study assessed ketogenic diets from the people's perspective of side effects, attitude, and quality of life. METHOD: This retrospective observational study evaluated people who experienced or still practice a ketogenic diet. Health-related quality of life, the standard four-item set of healthy days core questions, was employed. We distributed the survey as an electronic self-assessment using Google Forms. The data were reviewed and automatically copied into a personal computer, arranged in a data-sheet in Microsoft Excel, and analyzed using Statistical Package for the Social Sciences version 27 (Armonk, NY: IBM Corp.). The data were mainly expressed as numbers and percentages. RESULTS: A total of 226 subjects who adopted a ketogenic diet were interviewed to explore their diet experience. Females were slightly more than males (52.7% vs. 47.3%), and more than one-half (55.3%) of this study population aged 18-35 years. Obesity accounted for 55.3%, and the majority of the respondents (69.9%) adopted a ketogenic diet for more than one month. Among the most frequently reported symptoms were nausea (mild, 29.2%; moderate, 16.4%; severe nausea, 5.8%), dizziness (mild, 39.8%; moderate, 27.4%; severe, 11.5%), polyuria (72.1% in total), and lethargy (69.7%). Furthermore, 90.3% of them felt happy about adopting a ketogenic diet, and 81.9% would recommend it for anyone who wants to lose weight. CONCLUSION: A ketogenic diet was practiced mostly for one to six months, making it a short-term solution to weight loss. The outcomes of the participants approved the efficacy of the ketogenic diet in weight reduction. Different symptoms and side effects occurred with varying intensities, especially in the first few days of adopting this diet. Overall, the ketogenic diet did not affect the quality of life and yielded a very positive overall experience.
