    Cholelithiasis and Fatty Liver disease are usually observed to coexist. Patients who have gallstones also have Fatty Liver as both of the conditions have same associated risk factors I.e., diabetes mellitus, gender, age, obesity, metabolic syndrome, insulin resistance and high lipids level. Non-Alcoholic Fatty Liver Disease (NAFLD) is also an independent accountable risk factor for the formation of gallstones. We aimed to determine whether there is any correlation between cholelithiasis and fatty liver disease. The study was conducted in Lahore General Hospital, Lahore, Pakistan. The data was collected from March 24,2021 to May 24,2021. Informed consent was taken from all the participants. We did a cohort study comprising the data of 51 patients undergoing physical checkup. The data gathered included age, gender and whether they had normal or fatty liver. Cholelithiasis was diagnosed by confirming the presence of gallstones on abdominal ultrasonography after fasting for approximately 8hrs. it was an observational study for the assessment of correlation between cholelithiasis and fatty liver in the participants. A Total of 51 patients with cholelithiasis were included in our study. Most of the patients were 29 to 70 years of age. The average age of the patients was 42.3 ± 10.1 years. Out of 51 patients, there were 60.8% (P=31) females and 39.2%(P=20) males. Out of 51 cholelithiasis patients there were 31.4%(P=16) had Normal Liver and 68.6%(P=35) were positive with Fatty liver disease. Patients with stone size ranges from 1.90mm to 4.6mm hade Grade 1 Fatty liver as shown in table-5.4, Grade 2 Fatty liver was seen in patients with stone size ranges from 4.5mm to 5.8mm. Fatty liver Grade 3 was not observed in any included patient with cholelithiasis. Results of our study showed that both cholelithiasis and Fatty Liver disease are correlated with each other. Females are at higher risk to be affected by these with diseases. Early detection of Fatty liver in patients of cholelithiasis can help patients to prevent them further complications regarded to fatty liver and cholelithiasis and can play important role in health care of society.

    Why bias matters in medicine: Qualitative insights from anonymous, online reports

    No full text
    PURPOSE: Bias has been shown to influence the experience and mental health of healthcare professional trainees and faculty in academic medicine. The authors investigated the character and impact of self-reported bias experiences sustained in the academic medical arena that were submitted anonymously online to the website SystemicDisease.com. METHOD: This qualitative study analyzed 22 narratives submitted online to SystemicDisease.com between September 2015 and March 2017. Both deductive and inductive content analysis was performed, using a combination of a priori axial and open coding. RESULTS: The most commonly reported biases occurred on the basis of race and/or gender. Multiple submitters indicated this bias had influenced or threatened their intended career trajectory. Healthcare professional trainees also expressed altruistic concerns toward other underrepresented individuals as well as toward patients from disadvantaged backgrounds. CONCLUSION: Racial and gender bias constitute a considerable barrier for trainees and professionals in academic medicine. Institutional awareness of these impacts can inform interventions designed to foster a more inclusive professional climate

    Sex-disparities in chest pain workup: a retrospective cohort review of a university based clinical decision pathway

    Abstract Background Females have historically lower rates of cardiovascular testing when compared to males. Clinical decision pathways (CDP) that utilize standardized risk-stratification methods may balance this disparity. We sought to determine whether clinical decision pathways could minimize sex-based differences in the non-invasive workup of chest pain in the emergency department (ED). Moreover, we evaluated whether the HEART score would minimize sex-based differences in risk-stratification. Methods We conducted a retrospective cohort review of adult ED encounters for chest pain where CDP was employed. Primary outcome was any occurrence of non-invasive imaging (coronary CTA, stress imaging), invasive testing, intervention (PCI or CABG), or death. Secondary outcomes were 30-day major adverse cardiac events (MACE). We stratified HEART scores and primary/secondary outcomes by sex. Results A total of 1078 charts met criteria for review. Mean age at presentation was 59 years. Females represented 47% of the population. Low, intermediate, and high-risk patients as determined by the HEART score were 17%, 65%, and 18% of the population, respectively, without any significant differences between males and females. Non-invasive testing was similar between males and females when stratified by risk. Males categorized as high risk underwent more coronary angiogram (33% vs. 16%, p = 0.01) and PCI (18% vs. 8%, p = 0.04) than high risk females, but this was not seen in patients categorized as low or intermediate risk. Males experienced more MACE than females (8% vs. 3%, p = 0.001). Conclusions We identified no sex-based differences in risk-stratification or non-invasive testing when the CDP was used. High risk males, however, underwent more coronary angiogram and PCI than high risk females, and consequently males experienced more overall MACE than females. This disparity may be explained by sex-based differences in the pathophysiology driving each patient’s presentation

    All-Printed Flexible Memristor with Metal–Non-Metal-Doped TiO2 Nanoparticle Thin Films

    A memristor is a fundamental electronic device that operates like a biological synapse and is considered as the solution of classical von Neumann computers. Here, a fully printed and flexible memristor is fabricated by depositing a thin film of metal–non-metal (chromium-nitrogen)-doped titanium dioxide (TiO2). The resulting device exhibited enhanced performance with self-rectifying and forming free bipolar switching behavior. Doping was performed to bring stability in the performance of the memristor by controlling the defects and impurity levels. The forming free memristor exhibited characteristic behavior of bipolar resistive switching with a high on/off ratio (2.5 × 103), high endurance (500 cycles), long retention time (5 × 103 s) and low operating voltage (±1 V). Doping the thin film of TiO2 with metal–non-metal had a significant effect on the switching properties and conduction mechanism as it directly affected the energy bandgap by lowering it from 3.2 eV to 2.76 eV. Doping enhanced the mobility of charge carriers and eased the process of filament formation by suppressing its randomness between electrodes under the applied electric field. Furthermore, metal–non-metal-doped TiO2 thin film exhibited less switching current and improved non-linearity by controlling the surface defects

    Telomere length (TEL) regulation is important for genome stability and is governed by the coordinated role of shelterin proteins, telomerase (TERT), and CST (CTC1/OBFC1/TEN1) complex. Previous studies have shown the association of telomerase expression with the risk of acute lymphoblastic leukemia (ALL). However, no data are available for CST association with the ALL. The current pilot study was designed to evaluate the CST expression levels in ALL. In total, 350 subjects were recruited, including 250 ALL cases and 100 controls. The subjects were stratified by age and categorized into pediatrics (1–18 years) and adults (19–54 years). TEL and expression patterns of CTC1, OBFC1, and TERT genes were determined by qPCR. The univariable logistic regression analysis was performed to determine the association of gene expression with ALL, and the results were adjusted for age and sex in multivariable analyses. Pediatric and adult cases did not reflect any change in telomere lengths relative to controls. However, expression of CTC1, OBFC1, and TERT genes were induced among ALL cases. Multivariable logistic regression analyses showed association of CTC1 with ALL in pediatric [β estimate (standard error (SE)= −0.013 (0.007), p = 0.049, and adults [0.053 (0.023), p = 0.025]. The association of CTC1 remained significant when taken together with OBFC1 and TERT in a multivariable model. Furthermore, CTC1 showed significant association with B-cell ALL [−0.057(0.017), p = 0.002) and T-cell ALL [−0.050 (0.018), p = 0.008] in pediatric group while no such association was noted in adults. Together, our findings demonstrated that telomere modulating genes, particularly CTC1, are strongly associated with ALL. Therefore, CTC1 can potentially be used as a risk biomarker for the identification of ALL in both pediatrics and adults
