Tracking Side Effects of the COVID-19 Vaccine in Mymensingh District of Bangladesh

The Coronavirus disease 2019 (COVID-19) has turned into a worldwide human tragedy and economic devastation. There had an intensive search for an effective drug against the coronavirus but not led to any breakthrough agents. Only one choice was left namely an effective and safe vaccine. Many people are ambivalent regarding corona vaccines because they also fear possible side effects from vaccination. This study was designed to track the side effects after first and second dose of the Oxford-AstraZeneca vaccines used in Mymensingh district of Bangladesh. This cross-sectional descriptive type of observational study was conducted in Mymensingh Medical College, Mymensingh, Bangladesh during the period of five months from 1 February, 2021 to 30 June, 2021 among 293 purposively selected vaccine recipients who received two doses of the Oxford-AstraZeneca vaccines. Data were collected by face to face interview of the selected vaccine recipients using a semi-structured questionnaire. Data were inputted into SPSS version 26.0. Qualitative data were summarized by percentage and quantitative data were summarized by mean and standard deviation. Necessary bivariate and multivariate analysis was done. Mean age of the respondents was 40.3 years with a standard deviation of ±8.7 years. Among the vaccine recipients female were 159(54.3%) and male were 134(45.7%). The most of the vaccine recipients were graduate and master 256(87.3%) and more than half of the vaccine recipients (156, 53.2%) were government service holder. The most of the vaccine recipients (242, 86.0%) were from urban area and 263(89.8%) vaccine recipients were non-smoker. Sixty eight (23.2%) of the vaccine recipients had different types of co-morbidities. It was found that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects after second dose. The difference in occurrence of side effects of first and second dose was statistically highly significant (p<0.001). Pain on the injection site was present in 172(58.7%) vaccine recipients after first dose and in 142 (48.5%) after second dose. Fever was prevalent in 98 (33.4%) after first dose and in 61 (20.8) after second dose. Headache was in 61(20.8%) and in 22(7.5%) after first and second dose respectively. Thirty one (10.6%) vaccine recipients had loose motion after first dose and 26(8.9%) had this after second dose. First dose of vaccination caused nausea in 28(9.6%) and second dose caused it in 16(5.5%) vaccine recipients. Joint pain was prevalent in 24(8.2%) after first dose and in 15(5.1%) after second dose. Rash was present in 9(3.1%) and in 3(1.0%) after first and second dose respectively. Cough was present in 5(1.7%) after first dose and in 2(0.7%) after second dose. Each 2(0.7%) had history of fainting and bodyache and 1(0.3%) reported intense weakness after first dose only. Side effects of first dose of AstraZeneca vaccine were more prevalent in female (124, 78.0%) than male (93, 69.4%). The side effects of second dose of AstraZeneca vaccine were also more prevalent in female (103, 64.8%) than male (59, 44.0%). The study results revealed that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects on second dose of the Oxford-AstraZeneca vaccine. Commonly experienced side effects were pain in the injection site, fever, headache, diarrhoea and joint pain. Most of the people tolerated these side effects and did not use any medicine.

Expression analysis of transcription factors in sugarcane during cold stress

Transcription factors (TF) are a wide class of genes in plants, and these can regulate the expression of other genes in response to various environmental stresses (biotic and abiotic). In the current study, transcription factor activity in sugarcane was examined during cold stress. Initially, RNA transcript reads of two sugarcane cultivars (ROC22 and GT08-1108) under cold stress were downloaded from SRA NCBI database. The reads were aligned into a reference genome and the differential expression analyses were performed with the R/Bioconductor edgeR package. Based on our analyses in the ROC22 cultivar, 963 TF genes were significantly upregulated under cold stress among a total of 5649 upregulated genes, while 293 TF genes were downregulated among a total of 3,289 downregulated genes. In the GT08-1108 cultivar, 974 TF genes were identified among 5,649 upregulated genes and 283 TF genes were found among 3,289 downregulated genes. Most transcription factors were annotated with GO categories related to protein binding, transcription factor binding, DNA-sequence-specific binding, transcription factor complex, transcription factor activity in RNA polymerase II, the activity of nucleic acid binding transcription factor, transcription corepressor activity, sequence-specific regulatory region, the activity of transcription factor of RNA polymerase II, transcription factor cofactor activity, transcription factor activity from plastid promoter, transcription factor activity from RNA polymerase I promoter, polymerase II and RNA polymerase III. The findings of above results will help to identify differentially expressed transcription factors during cold stress. It also provides a comprehensive analysis of the regulation of the transcription activity of many genes. Therefore, this study provides the molecular basis for improving cold tolerance in sugarcane and other economically important grasses.

Depression, Anxiety and Stress among the Students and Their Academic Performance in Selected Medical Colleges of Bangladesh

Medical education is associated with a great psychological distress that affects many aspects of students' lives, including their academic performance and professional development. The objective of the study was to determine the level of depression, anxiety and stress and their academic performance among fifth year medical students. This was a cross-sectional descriptive study conducted in Dhaka Medical College, Mymensingh Medical College, Anwar Khan Modern Medical College and Community Based Medical College of Bangladesh. For this purpose, 359 students were taken as sample and self-administered semi-structured questionnaire was used to collect data. Depression, anxiety and stress were assessed by using short form DASS-21 BV score. The results showed that, the mean age of students was 22.74 years with female predominance 230(64.0%). Majority 319(88.9%) of the respondents' parents monthly income was ≤100000 taka and one third 126(35.1%) respondents' monthly study expenditure was in between 5001 to 10000 taka. Four fifth 317(88.0%) of the respondents came from nuclear type of family and two third 245(68.2%) lived in hostel. Half 178(50.0%) of the respondents were eldest in birth order. Majority 221(61.6%) of the students were admitted to medical college by their own motivation and interest. Symptoms of depression, anxiety and stress were present in 179(49.9%), 215(59.9%) and 161(44.8%) respectively. No significant association was found between academic performance with depression or anxiety or stress, except class attendance of Gynaecology and Obstetrics which was significantly associated with stress (p=0.016); the students who suffered from more stress, their class attendance were very poor. Students who reappeared in MBBS professional examination were significantly associated with depression (p=0.032) and stress (p=0.036). There was significant difference between students of public and private medical colleges in terms of anxiety (p=0.031) that is students of public medical colleges more suffered from depression, anxiety and stress in comparison to private medical colleges. Depression (p=0.001) and anxiety (p=0.010) were significantly associated with motivation to study MBBS. No significant difference of depression, anxiety or stress was found with sex difference. This study revealed that fifth year MBBS students suffered more from depression, anxiety and stress. The causes of depression, anxiety and stress should be identified and resolved to improve their mental health and academic performance.

Characterization of wheat-Thinopyrum bessarabicum genetic stock for stripe rust and Karnal bunt resistance

Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup of most crops. Narrowed genetic makeup of these crops has made them vulnerable towards disease and insect epidemics. For sustainable crop production, genetic variability of these crops must be broadened against various biotic and abiotic stresses. One of the ways to widen genetic configuration of these crops is to identify novel additional sources of durable resistance. In this regard crops wild relatives are providing valuable sources of allelic diversity towards various biotic, abiotic stress tolerance and quality components. For incorporating novel variability from wild relative's wide hybridization technique has become a promising breeding method. For this purpose, wheat-Th. bessarabicum amphiploid, addition and translocation lines have been screened in field and screen house conditions to get novel sources of yellow rust and Karnal bunt resistant. Stripe rust screening under field conditions has revealed addition lines 4JJ and 6JJ as resistant to moderately resistant while addition lines 3JJ, 5JJ, 7JJ and translocation lines Tr-3, Tr-6 as moderately resistant wheat-Thinopyrum-bessarabicum genetic stock. Karnal bunt screening depicted addition lines 5JJ and 4JJ as highly resistant genetic stock. These genetic stocks may be used to introgression novel stripe rust and Karnal bunt resistance from the tertiary gene pool into susceptible wheat backgrounds.

Adjuvant Tyrosine Kinase Inhibitors in Renal Cell Carcinoma: A Concluded Living Systematic Review and Meta-Analysis

PURPOSE

Multiple large clinical trials have investigated adjuvant tyrosine kinase inhibitors (TKIs) to reduce the risk of cancer recurrence and progression to metastasis in high-risk renal cell carcinoma. We sought to maintain living and interactive evidence on this topic, until a high level of certainty is reached for key clinical outcomes such that further updates become unnecessary and unlikely to change clinical practice.

METHODS

We created a living interactive evidence synthesis platform to maintain a continuously updated meta-analysis on TKI monotherapy in adjuvant renal cell carcinoma. We implemented an automated search strategy with weekly updates to identify randomized phase 2 and 3 clinical trials. Study selection, appraisal, and data extraction were done in duplicate. Cumulative meta-analysis was performed using Analyzer Module in Living Interactive Evidence platform. For each outcome (overall survival [OS], disease-free survival [DFS], and all-cause and treatment-related adverse events), we assessed certainty of evidence using GRADE approach and conducted trial sequential analysis.

RESULTS

This final update includes five randomized trials including recently updated data from PROTECT trial. Meta-analysis shows that adjuvant TKI monotherapy offers no benefit in OS (hazard ratio, 1.01; 95% CI, 0.91 to 1.12, high certainty) or DFS (hazard ratio, 0.92; 95% CI, 0.86 to 1.00, high certainty) and significantly increases adverse event risk. Lack of benefit was consistent across subgroups including highest-risk patients (test for subgroup differences: P = .32). Optimal information size criteria were met, and there was high certainty of evidence for lack of DFS and OS benefit for adjuvant TKIs.

CONCLUSION

There is no guidance on when to stop maintaining a living review. In this example, we used trial sequential analysis and high certainty of evidence (future clinical trials unlikely to change current conclusions) as a benchmark to conclude a living review in view of convincing evidence.

Episode of Hepatitis C viral infection in the people of Swat, Pakistan

Infectious agents cause serious diseases in humans worldwide and are responsible for the high rate of morbidity and mortality. The prevalence and epidemiology of infectious disease (HCV) in the hospital visited patients referred by the physicians through the initial findings and their associated risk factors were studied in Swat. The data of 174 infected patients were collected during the period of 2015 to 2017 from two clinical laboratories of Tehsil Matta Swat. Inform consent form was taken before blood collection. After taking informed consent blood samples were collected and ICT test was performed and then ICT positive cases were conform through PCR. A total of 174 ICT positive samples [106 male and 68 females] were included in this study. Age was considered from 10 to 72 years. Of the 174 ICT strip positive, 99 [63 males, 36 females] were confirmed through PCR. The prevalence rate was recorded 56.89%. I.V/I.M injection was recorded in 100% of the individuals. Visits to the barber shop was reported in (58%) of the individuals, married individuals were (81.0), surgical operation was reported in (44.8%), sharing toothbrush was observed in (29.9%), piercing was reported in (39.7%), family history was reported in (26.4%), dental treatment was observed in (21.8%), jaundice were (13.2%) and tattooing was (1.7%). Blood transfusion, surgical operations, Jaundice, family history and dental treatment were found significant risk factors for acquiring HCV infection. It was concluded that proper implementation of precautionary measures should be needed to control the spread of HCV in far near future.

Disparities in reporting and representation of women, older adults and racial minorities in immune checkpoint inhibitor (ICI) clinical trials

6549

Background: Representation and outcomes of women, older adults, and racial minorities in ICI trials has not been previously described. Methods: MEDLINE and Embase were searched to identify ICI RCTs. Data for trial characteristics, proportion of trials reporting race, age and sex as well as the proportion of patients by race, age and sex enrolled in ICI trials was collected. Descriptive statistics were reported for trials reporting minority representation and proportion of included patients by race, age and sex. Disparities in representation were calculated using enrollment incidence disparity (EID) and enrollment incidence ratios (EIR) by comparing trial enrollment against U.S. population-based estimates acquired from the SEER 18 incidence database. The relationship of EID to key trial characteristics were compared using standard parametric and non-parametric statistical tests. Trends in EIR were analyzed using the Joinpoint Regression Analysis software. Results: 108 ICI trials from 2009 to 2020 with 48,360 patients were included in this analysis. All RCTs reported sex (101/101). 78 trials reported race (72%), of which only 41 trials (38%) reported data on all 5 U.S. racial categories (Black, White, Asian, Pacific Islander and Native American). Participation of Black patients was reported in 66 trials (61%), White participants in 78 trials (72%), Asians in 69 trials (64%), Native Americans and Pacific Islanders in 41 trials (38%), and Hispanics in 24 trials (22%). Age categories were inconsistently defined, and 80 trials (74%) reported the proportion of patient by age categories. Subgroup analyses of clinical outcomes by race, age and sex were reported in 17 (22%), 62 (79%) and 57 (73%) trials respectively. Women (trial proportion [TP]: 32%; EIR: 0.77), patients aged ≥ 65 years (TP: 42%; EIR: 0.74), Black participants (TP: 1.8%; EIR: 0.17) and Hispanic participants (TP: 5.9%; EIR: 0.67) were largely underrepresented, and Asians were overrepresented (TP: 15.9%; EIR: 2.64). Black patients were underrepresented across all cancer types. Similarly, women, older adults ( > 65 years of age) and Hispanic patients were consistently underrepresented across cancer types with few exceptions. Representation of older adults increased significantly from 2010-2020 (APC: 2.72), while representation of Black patients decreased significantly from 2009-2020 (APC: -23.37). Black patients were found to be significantly underrepresented in phase III trials (p = 0.0005), trials with OS as the primary endpoint (p = 0.004), and PD1 inhibitor trials (p = 0.002). Hispanics were significantly underrepresented in PD1 inhibitor trials (p = 0.003). Conclusions: There is both suboptimal reporting about participation and underrepresentation of women, racial minorities (particularly Black patients) and older adults in ICI trials as compared to their cancer incidence.

Effect of different protein based feed on the growth of mahseer

For the proper growth of fish, it is necessary to feed the fish with a proper and balanced diet. A study was conducted to find out the effect of different protein-based diets on fingerlings of Tor putitora (mahseer). A feed with dietary protein levels of 35%, 40%, 45%, and 50% were prepared. The effect of different protein-based feed on weight gain, standard growth rate (SGR), food conversion ratio (FCR), percent weight gain, food conversion efficiency (FCE), and protein efficiency ratio (PER) was studied. An increase was observed in the growth rate with an increase in protein concentration up to 45%. The fingerlings fed a 45% protein diet shown the highest growth, followed by 50%, 40%, and 35%. The SGR value was greatest for 45% protein diet (8.56) followed by 50% and 40%, while the least values were observed for 35% protein feed (1.57). The same trend was observed for FCE. The highest PER values was observed in fishes fed 45% protein-based feed (0.65) followed by 50% (0.56), 40% (0.38) and35% (0.17). The food conversion ratio was lowest for 45% protein diet (3.41), while the greatest for 35% protein feed (16.85). It was concluded that a 45% protein-based diet was the best feed formulation for higher production of Tor putitora. However, research on the same percentage of protein diet is recommended for yearlings.

Evaluation of microbial contamination level and the drug susceptible pattern of the isolates cultivated from famous dessert food

Present study endeavored to evaluate the microbial contamination level along with their drug resistant pattern in some popular desert food items collected from different food shops in Dhaka city, Bangladesh. The microbial evaluation was conducted through conventional cultural methods and drug susceptibility test was executed through disc diffusion method. All the samples were found to be contaminated with heterotrophic bacteria as well as fungi within the range of 103 to 105 CFU/g. In case of specific microflora, the growth of Staphylococcus spp. was very high in sweet, faluda, milk cake and ice cream as estimated up to 105 CFU/g, halua and sweet yogurt showed 104 CFU/g while rest of the samples revealed 103 CFU/g. E. coli was found only in faluda and ice cream up to 103 CFU/g whereas Klebsiella spp. was estimated in all the samples within the range of 102 CFU/g to 105 CFU/g. Salmonella spp., Pseudomonas spp. and Bacillus spp. were totally absent in all the samples. Most of the isolates were found to be resistant against most of the antibiotics. Meanwhile, streptomycin (10 µg), gentamicin (10 µg), azithromycin (15 µg), and nalidixic acid (5 µg) were effective drug against both E. coli and Staphylococcus spp.

Outcome of Management of Liver Abscess by Surgical Approach in a Tertiary Care Hospital

Liver abscess is a serious, life threatening condition. A recent development in the management of liver abscesses, facilitated by advances in diagnostic and interventional radiology, has decreased mortality rates. The purpose of this study is to search for the clinical presentations and surgical outcomes of liver abscess in our country. The markers of the outcome are mortality, duration of hospital stay and complications such as wound infection, residual disease following surgery, biliary leakage, intra abdominal abscess formation. This observational cross sectional study was conducted in Mymensingh Medical College & Hospital (MMCH), Bangladesh for 12 months from 1st January 2017 to 31st December 2017. Total 25 patients presenting with the features of liver abscess were included in this study by convenient and purposive sampling according to the inclusion and exclusion criteria. Surgical principles of liver abscess management were applied and outcomes were observed. The patients were diagnosed on the basis of clinical feature, findings of abdominal ultrasound and occasionally by doing CT scan. Most of the patients (28%) were in the age group of 51-60 years. Regarding sex distribution majority of the patients (64%) was male. Most of patients presented with fever (92%), anorexia and vomiting (32%), upper abdominal pain (84%). Hepatomegaly and reactive pleural effusion are the important findings present in 9(36%) and 8(32%) patients respectively. Size of the liver abscess was more than 5cm in 72% patients. Among the patients right lobe was predominantly involved. It was found during laparotomy that 4 patients (16%) had spontaneous rupture of abscess into peritoneal cavity. One (4%) patient developed biliary leakage after surgical drainage. No intra abdominal abscess or residual diseases was observed after surgery. Among the patients 24% developed wound infection. The overall mortality rate was 12%. The median length of hospital stay was 8 days (range: 1-15 days). Outcome of surgical drainage of liver abscess in tertiary care hospital of our country shows satisfactory result. So, patients with large multiple liver abscess, septic shock, failures of percutaneous drainage should be treated by early open surgical intervention.

Mortality and morbidity of stairlift injuries: Analysis of the UK TARN database

AIMS

To investigate the incidence and pattern of injury in patients with a diagnosis of a fall from a stairlift.

METHODS

Data was analysed from the Trauma Audit and Research Network (TARN) database from 2000 to 2018 for those recorded suffering stairlift related injuries between the ages of 40-100 years. Patient demographics, injury mechanism and pattern, mortality rate and height of fall were analysed.

RESULTS

1069 patients were identified in the initial search with 651 having an eligible mechanism of injury. The mean age was 82 (range 41.4-100.1) years. The most common site of injury was the limbs (49.2%) with the most severe injuries to the head (mean AIS 3.1). The mean ISS was 12.5 (Range 1-75). There was no relationship between height of fall and ISS (r_s 0.054 p = 0.4). Individuals were 78% more likely to have an ISS score of 15 or more if they had a head injury, (OR: 0.12; 95% CI: 0.06-0.24) and 79% more likely to have sustained an injury to the thorax (OR: 0.21; 95% CI: 0.11-0.41). Injury to the head was 95% more likely in individuals with an ISS score greater than 25 points or more (OR: 0.05; 95% CI: 0.01-0.16) and 69% more likely for those who sustain injury to the thorax. Individuals with an ISS score of 25 points or more were 18 times more likely to have sustained injury getting off their stair lift compared to any other method of falling from their stair lift. Mortality was associated with injuries to the thorax in those aged 70 years or below, injuries to the face, spine and limb for those aged 71-85 years and with head injury in those over 85 years. The overall mortality rate was 15.7%.

CONCLUSION

Falls from stairlifts commonly result in limb injuries and most severe injuries are sustained to the head. When patients fall getting off from astairlift, have injuries to their head or thorax they have a higher ISS. The overall mortality is 15.7%. Given the increasing use of stairlifts in our ageing population, strategies should be considered to make these safer.

Novel evidence synthesis system to support living systematic reviews and living guidelines for cancer immunotherapy

2054

Background: Systematic reviews that summarize the toxicity of Immune checkpoint inhibitors (ICIs) become outdated very soon after publication. Therefore, we reported results of a toxicity meta-analysis at 2019 ASCO meeting and informed the intent to create a living systematic review (LSR). LSRs combine human and machine effort and support rapid evidence synthesis and living clinical practice guidelines. Now, we report our experience maintaining a LSR on toxicity of ICIs. Methods: Steps include quarterly literature searches to identify new clinical trials reporting ICI-associated adverse events (AEs), AI-enabled screening of new citations which meet the inclusion criteria, automated cumulative meta-analysis and an online reporting platform. Standard data formats and protocols were designed for inputting text, tables and graphics. Software was written to interpret these data and output the information in the appropriate format, such as a forest plot and summary tables. Finally, a dynamic interface that enables user inputs and displays the associated output was designed. Results: The LSR is continuously updated incorporating toxicity data from new clinical trials as it becomes available. We have screened 8000 relevant citations and summarized the odds of Grade 3 or higher AEs and AEs of special interest in patient receiving ICIs. The results are updated on quarterly basis and are available online. The results are updated on quarterly basis and will be available on a website at the time of publication. Prototype with dummy data is available at this link . This interface can also be manipulated via user input to organize and sort data tables and forest plots by type of cancer, name or mechanism (PD-1 or PD-L1) of ICI agent, single agent or combination, type of control arm, line of treatment and several other clinically relevant filters. For example, a user can instantaneously generate a meta-analysis summarizing the risk of colitis or pneumonitis in metastatic lung cancer trials with pembrolizmuab. Conclusions: This LSR engine can prospectively synthesize toxicity data from ICI trials in an efficient manner providing accurate and timely information for advanced clinical decision support at point-of-care. Efforts are ongoing to improve efficiency of screening, improve AI-enabled processes for automated screening and data abstraction, and test across multiple clinical questions.

A Comparative Study of Craniosonogram and CT scan of Brain in CNS Complication of Perinatal Asphyxia

Pereinatal asphyxia is one of the most important complications related with the process of birth and this complications affect not only the brain but also many other organs. The purpose of this cross sectional study is to compare the role of craniosonogram and CT scan of the brain to delineate the cerebral pathology in respondent of preterm and term infant and to assess the Kappa test for agreement. This study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of July 2015 to June 2017. A total number of 40 neonates clinically diagnosed as perinatal asphyxia referred for Craniosonogram and Computed tomography (CT) were included in this study. The test of agreement of USG in detection of neonatal cerebral pathology was calculated. Male to female ratio was 1:1.4. More than half (55.0%) patients were preterm age. The mean birth weight was found 2.3±0.6 kg and mean age was 22.7±12.7 days. Fifty five percent respondent mothers had antenatal check up and 27% had anemia, 11% had premature rupture of membrane, 9% had multiple pregnancy and 7% patient had hypertension. Cerebral pathology was found 28 and 31 cases by Craniosonogram and CT scan respectively. Germinal matrix hemorrhage/IVH (Intra ventricular hemorrhage) found 7(17.5%) in USG and 4(10.0%) in CT scan. Hypoxic ischaemic changes with mild ventriculomegaly observed 5(12.5%) in USG and 7(17.5%) in CT scan. Hypoxic ischaemic change found 4(10.0%) in USG and 5(12.5%) in CT scan. In USG evaluation of 28 patients having cerebral pathology & 16(72.7%) had in preterm group and 12(66.7%) in term group. In CT scan of brain 31 patients with cerebral pathology & 15(37.5%) in preterm group and 16(40.0%) in term group. CT scan found cerebral pathology 77.5% (31/40) cases and USG found 70.0% (28/40), with Kappa value was 0.551, which indicates that fair agreement between USG and CT scan for detection of cerebral pathology in respondent. Craniosonogram is a useful method in all neonates specially preterm to see the CNS complication of perinatal asphyxia.

Wide Stromal Mapping Using an Anterior Segment Optical Coherence Tomography

Purpose

To quantify and assess the reproducibility of the corneal stromal thickness profiles captured by the SD-OCT. Secondly, we correlated the zonal thicknesses to the age, gender and axial length.

Methods

We included 227 normal eyes of 227 patients with a maximum hypermetropia of +5 and myopia of –6 diopters (D). Subjects with an intraocular pressure exceeding 22 mm Hg, evidence of cataract formation, history of ophthalmic surgery or disease were excluded. Lastly, reproducibility was evaluated in a subset of 50 participants by means of an identical scan protocol repeated by 2 different OCT operators.

Results

Stromal values were consistently thicker in the peripheral cornea (p<0.001). Age was negatively correlated with approximately every sector of the stroma with notable exceptions of the center (r=0.117, p=0.088) and the superior inner (r=0.057, 0.409), middle (r=0.086, p=0.209) and outer locations (r=0.120, p=0.079). There was no statistical significance in most sectors when looking at the axial length, gender and K1/K2. This method was highly reproducible in terms of both the ICC and COV.

Conclusion

Corneal stromal mapping is highly reproducible and shows a negative correlation to age. Additionally, the periphery of the stroma is consistently thicker to the center. Other variables like gender and axial length show no relationship to the corneal stroma.

Adjuvant therapy in high-risk renal cell cancer: A systematic review and cumulative meta-analysis

708

Background: Patients with high risk non-metastatic renal cell cancer (RCC) are at significant risk of recurrence following nephrectomy. Previously, we reported no benefit of adjuvant tyrosine kinase inhibitor (TKI) treatment in high-risk patients. Since our most recent publication, efficacy results from the multicenter double-blind SORCE trial have become available. We updated our meta-analysis to include these additional data and performed a cumulative meta-analysis. Methods: PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials were searched to identify relevant RCTs. A generic variance-weighted random effects model was used to derive estimates for efficacy. Heterogeneity was assessed using the Cochran Q statistic and was quantified using the I2 test. The primary outcome was disease-free survival (DFS), defined as the interval between randomization and the first recurrence, the occurrence of metastasis or a secondary cancer, or death due to any cause. Statistical analysis was performed using Comprehensive Meta-Analysis version 3 (Biostat). Results: Five phase 3 trials were identified, enrolling 6531 patients. Two trials compared sunitinib with placebo (S-TRAC and ECOG-ACRIN), two compared sorafenib with placebo (ECOG-ACRIN and SORCE) and one trial each compared pazopanib (PROTECT) and axitinib (ATLAS) vs placebo. Cumulative evidence suggests that adjuvant therapy with TKIs showed no significant improvement in (DFS) hazard ratio [HR] of 0.93 (95% CI, 0.85-1.02), compared to placebo. There was no significant heterogeneity among included trials ( I2= 52%, P= .41). Overall, the trials were at low risk of bias. Conclusions: Adjuvant vascular endothelial growth factor tyrosine kinase inhibitors in high-risk renal cell carcinoma did not improve DFS as compared to placebo. Improved patient selection using better prognostic biomarkers or scoring systems may identify subsets of patients who can benefit from adjuvant treatments. Toxicity estimates will be updated as data from SORCE trial publication becomes available.

Antithyroid Antibody Status in Non-Pregnant Adult Bangladeshi Patients with Subclinical Hypothyroidism

Sub clinical hypothyroidism (SCH) is common in clinical practice. Autoimmunity is thought to be the most important cause of SCH. In this cross-sectional study, we investigated 120 SCH patients and 100 healthy controls attending the Endocrinology Outpatient Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from June 2014 to April 2015 for anti-thyroid antibodies (anti-TPO and anti-Tg). Measurement of serum TSH, FT4, anti-TPO, and anti-Tg antibodies were done by using the chemiluminescent sequential immunometric assay. SCH patients had a higher mean age; the frequencies of female subjects, those having family history of thyroid disease or other autoimmune diseases, and goiter were higher in SCH group than in the control group. Forty-five percent (45%) of SCH patients were positive for anti-thyroid antibodies (23.3% for both anti-TPO and anti-Tg, 16.7% for only anti-TPO, and 5% positive for only anti-Tg) in comparison to only 10% anti-thyroid antibody positive controls (none for both antibodies, 8% for only anti-TPO, and 2% positive for only anti-Tg). The SCH subjects in the lower age group, females and with a TSH >10μIU/mL had the higher frequency of thyroid autoimmunity. Female gender, high socioeconomic condition, the presence of other autoimmune diseases, the presence of goiter and TSH >10μIU/mL were associated with higher odds of anti-thyroid antibody positivity in the SCH group, though none were statistically significant. The frequency of anti-thyroid antibody was higher in SCH and was more prevalent among the females, younger patients and those having a goiter, other autoimmune diseases, and TSH >10μIU/mL.

Lifestyle and Depression in Urban Elderly of Selected District of Bangladesh

Global population is ageing and Bangladesh has one of the fastest growing ageing populations in this region. Growth in the elderly population relative to other age groups challenges existing health services, family relationships and social security. Combined with this, depression has become a major mental health problem for elderly people especially for urban elderly for nuclear family norm in urban areas. The study was descriptive type of cross-sectional in nature and was conducted in Rangpur Medical College Hospital, Rangpur & Prime Medical College Hospital, Rangpur, Bangladesh. The objective of this study was to assess the lifestyle and level of depression in urban elderly. Depression was measured by questionnaire of geriatric depression scale among 254 respondents. 87.8% of the respondents were age between 60-70 years. Majorities (63%) of the respondents were male, 54% of the respondents lived in nuclear type family and the rest (46%) in joint type of family. Among respondents near half (47.2%) of the respondents found Mild depressive, around one third (32.7%) were severe depressive, and the rest (20.1%) were normal. There was significant association between occupational status of the respondents and depression (x² = 45.600, df=14, p=0.000). Farmers unemployed found severely depressive (52.1%) followed by day-labourer (50%) and businessmen (37.5%). There was significant association between financial self dependency and depression of the respondents (x²= 34.072, df=4, p=0.000). Severe depression (43.8%) was found among those who were not financially self dependent. There was also significant association between monthly income and depression of the respondents (x²= 67.327, df=8, p=0.000). The study also found that lower income group (<Tk 10000) suffer more from severe depression (42.1% vs. 16.67%) than that of higher income group (Tk 50000-99999). Another significant association found between respondents living with family and depression (x²=16.025, df=2, P=0.000). Respondents those not living with family were suffering more from severe depression (55.55%). Association between social activity and depression (x²=31.724, df=4, p=0.000) revealed that those not involved in social activities were in severe depression (40.55%). The study concluded that lifestyle factors and socio-demographic conditions directly influence the state of depression. Those who lead a healthy social life with friends and family, with a stable income source are less prone to severe depression and vice versa. The study recommended the formulation of strategies for the well being of urban elderly that should include social awareness about positive lifestyle changes, social mobilization, health assurance, and response from the government so that depression and its associated serious diseases can be prevented.
