RESUMEN

PURPOSE: The comparative effectiveness of radical prostatectomy (RP) versus radiation therapy (RT) for prostate cancer remains a largely debated topic. Utilizing a provincial population-based linked data set from an equal-access, universal health care system, we sought to compare outcomes among patients treated with either radiation or prostatectomy for nonmetastatic prostate cancer. MATERIALS AND METHODS: We performed a retrospective cohort study by linking several administrative data sets to identify patients who were diagnosed with prostate cancer between 2004 and 2016 in Manitoba, Canada and who were subsequently treated with either RP or RT. Cox proportional hazard models with inverse probability of treatment weighting were used to compare rates of all-cause mortality, as well as prostate cancer specific mortality (PCSM) between patients who underwent RP vs RT. RESULTS: During the study period, 2,540 patients underwent RP and 1,895 underwent RT for prostate cancer. Unadjusted overall survival was higher for RP vs RT (5-year overall survival 95.52% for RP compared with 84.55% for RT, p <0.0001). In inverse probability of treatment weighting-adjusted Cox regression analysis, compared to patients in the RP groups, patients in the RT group had an increased rate of all-cause mortality (HR 1.93, 95% CI 1.65-2.26, p <0.0001), and PCSM (HR 3.98, 95% CI 2.89-5.49; p <0.0001). CONCLUSIONS: RT was associated with higher all-cause mortality and PCSM rates compared with RP. These findings highlight the importance of comparative effectiveness research to identify treatment disparities and warrant further investigation.

RESUMEN

PURPOSE: Non-surgical skills involving hand-eye coordination and bimanual dexterity may have a transferable impact on the acquisition of ureteroscopy skills. In this study, we aim to investigate the predictors of initial flexible ureteroscopy skills among novice trainees. METHODS: This was a prospective study involving students with no prior ureteroscopy exposure. Non-surgical parameters were assessed with a detailed survey, including demographics, video game, and musical history. Musical ability was objectively evaluated with the mini-Profile of Music Perception Skills test. Ureteroscopic performance was evaluated using a Boston Scientific© flexible ureteroscope on a bench model. Each participant completed diagnostic ureteroscopy and stone extraction. Outcomes included both speed and quality of performance, based on an Objective Structured Assessment of Technical Skills rubric. RESULTS: A total of 28 pre-clerkship medical students and 10 urology residents were included. Age and musical background were not associated with ureteroscopic aptitude. Those with video game history tended to perform ureteroscopy tasks faster with a higher OSATS score, although no statistical significance was reached. Male gender was associated with faster task completion with statistically higher OSATS score independent of video game activities (p = 0.011), however, the absolute score difference was small. CONCLUSIONS: Among novice trainees, musical and video game experience was not predictive of ureteroscopy skills. Male gender was associated with slightly faster and higher ureteroscopy technique scores, however, the differences are small and unlikely to represent clinical significance. Nevertheless, the use of ureteroscopy trainer provides useful insights and should be adopted in training programs as a marker of skills progression.

RESUMEN

PURPOSE: Treatment selection for localized prostate cancer is guided by risk stratification and patient preferences. While socioeconomic status (SES) disparities exist for access to care, less is known about the effect of SES on treatment decision-making. We sought to evaluate whether income status was associated with the treatment selected (radical prostatectomy [RP] vs radiation therapy [RT]) for nonmetastatic prostate cancer in a universal health care system. MATERIALS AND METHODS: All men from Manitoba, Canada who were diagnosed with nonmetastatic prostate cancer between 2005 and 2016 and subsequently treated with RP or RT were identified using a provincial cancer database. SES was defined as neighborhood income by postal code and divided into income quintiles (Q1-Q5, with Q1 the lowest quintile and Q5 the highest). Multivariable logistic regression nested models were used to compare whether SES was associated with treatment type received. RESULTS: We identified 3,966 individuals who were diagnosed with nonmetastatic prostate cancer and were treated with RP (2,354) or RT (1,612). After adjusting for demographic and clinicopathological characteristics, as income quintile increased, men were incrementally more likely to undergo RP than RT (range Q2 vs Q1: adjusted OR 1.40, 95% CI 1.01-1.93; Q5 vs Q1: adjusted OR 2.30, 95% CI 1.70-3.12). CONCLUSIONS: As income levels increased there was a stepwise incremental increase in the odds of receiving RP over RT for localized prostate cancer. These results may inform initiatives to better understand the values, priorities and barriers that patients experience when making treatment decisions in a universal health care system.

RESUMEN

OBJECTIVE: To evaluate the predictive ability of mid-upper arm circumference (MUAC) for detecting severe wasting (weight-for-height Z-score (WHZ) <-3) among children aged 6-59 months. DESIGN: Cross-sectional survey. SETTING: Rural Uttar Pradesh, India. SUBJECTS: Children (n 18 456) for whom both WHZ (n 18 463) and MUAC were available. RESULTS: The diagnostic test accuracy of MUAC for severe wasting was excellent (area under receiver-operating characteristic curve = 0·933). Across the lower range of MUAC cut-offs (110-120 mm), specificity was excellent (99·1-99·9 %) but sensitivity was poor (13·4-37·2 %); with higher cut-offs (140-150 mm), sensitivity increased substantially (94·9-98·8 %) but at the expense of specificity (37·6-71·9 %). The optimal MUAC cut-off to detect severe wasting was 135 mm. Although the prevalence of severe wasting was constant at 2·2 %, the burden of severe acute malnutrition, defined as either severe wasting or low MUAC, increased from 2·46 to 17·26 % with cut-offs of <115 and <135 mm, respectively. An MUAC cut-off <115 mm preferentially selected children aged ≤12 months (OR=11·8; 95 % CI 8·4, 16·6) or ≤24 months (OR=23·4; 95 % CI 12·7, 43·4) and girls (OR=2·2; 95 % CI 1·6, 3·2). CONCLUSIONS: Based on important considerations for screening and case detection in the community, modification of the current WHO definition of severe acute malnutrition may not be warranted, especially in the Indian context.

RESUMEN

BACKGROUND & OBJECTIVES: Dyslipidaemia is a major contributor to cardiovascular morbidity, which is increased in HIV. Data on dyslipidaemia in Indians with HIV are scant. This study was undertaken to determine the predictors of dyslipidaemia and lipoatrophy in Indians with HIV infection and their relation with body composition parameters. METHODS: A total of 382 consecutive patients with HIV infection were screened, of whom 257 clinically stable patients, without any acute comorbidity, having at least one year follow up underwent biochemical and DEXA analysis. RESULTS: The most common dyslipidaemia was hypertriglyceridaemia (47.08%), followed by hypercholesterolaemia [total cholesterol (TC)] (38.91%) and low high-density lipoprotein (HDL) cholesterol (38.52%), in patients having median age 37 (32-42) yr and HIV duration 57 (33-101) months. Patients with at least one dyslipidaemia (78.99%) had significantly higher insulin resistance (IR), per cent body fat, per cent trunk fat (PTF) and trunk limb fat ratio (TLFR). Baseline CD4 count and delta CD4 count (change in CD4 count 6-12 months following ART) had significant inverse correlation with triglycerides and TC. Patients with highest triglycerides and cholesterol quartiles had significantly higher immune reconstitution, metabolic syndrome, IR, trunk fat mass (FM), PTF and TLFR, with comparable total FM. Logistic regression revealed that body mass index, HIV duration and PTF were independent predictors of hypertriglyceridaemia, with only PTF being significant predictor of hypercholesterolaemia. Every unit increase in PTF was associated with 13 and 4.1 per cent increased hypertriglyceridaemia and hypercholesterolaemia. Lipoatrophy was present in 8.57 per cent patients and was a poor predictor of dyslipidaemia. INTERPRETATION & CONCLUSIONS: : High occurrence of dyslipidaemia was observed in patients with HIV on anti retroviral therapy. Central adiposity (TFM) was the most important predictor of dyslipidaemia in these patients.

RESUMEN

Background & objectives: Data on bone mineral density (BMD) and sarcopenia are scant from young females with HIV. This study was conducted to determine occurrence, predictors and impact of body composition alterations on osteoporosis in pre-menopausal women with HIV. Methods: A total of 214 females with serologically documented HIV infection were screened, of whom 103 pre-menopausal women, 25-45 yr age, clinically stable, having at least one year follow up data, underwent hormonal and dual-energy X-ray absorptiometry analysis for BMD and body composition. Seventy five matched controls were also evaluated. Results: Females with HIV had significantly lower BMD and. Z: -score at lumbar spine (LS), total femur, neck of femur (NOF), and radius ultra-distal (UD) compared to controls. Osteoporosis at least at one site was observed in 34.95 per cent patients, compared to eight per cent in controls (P<0.001). Most common site of osteoporosis in females with HIV was radius UD (24.27%), followed by radius 33 per cent (17.48%), radius total (15.53%) and greater trochanter, NOF and LS (6.80% each). HIV patients had significantly lower bone mineral content, lean mass (LM), fat per cent, android (A) fat, gynoid (G) fat, and A/G ratio. LM and fat mass (FM) were -15.65 and -11.54 per cent lower in HIV patients, respectively. Osteoporosis patients had significantly higher use of antiretroviral therapy and lower LM, FM and fat per cent. On logistic regression, LM followed by A/G ratio and BMI were the best predictors of osteoporosis. Sarcopenia was observed in 17.5 per cent patients. Interpretation & conclusions: Our results showed that osteoporosis and sarcopenia were significant problems in young women with HIV. HIV was associated with greater LM loss, which was critical for bone health. Sarcopenia may predict low BMD in HIV.

RESUMEN

PURPOSE: We evaluated whether an animated bladder training video was as effective as standard individual urotherapy in improving bladder/bowel symptoms. MATERIALS AND METHODS: Patients 5 to 10 years old who scored greater than 11 on the bladder/bowel Vancouver questionnaire were included in a noninferiority randomized, controlled trial. Children with vesicoureteral reflux, neuropathic bladder, learning disabilities, recent urotherapy or primary nocturnal enuresis were excluded from analysis. Patients were randomly assigned to receive standard urotherapy or watch a bladder training video in clinic using centralized blocked randomization schemes. Bladder/bowel symptoms were evaluated at baseline and 3-month followup by intent to treat analysis. A sample size of 150 patients ensured a 3.5 difference in mean symptomology scores between the groups, which was accepted as the noninferiority margin. RESULTS: Of 539 screened patients 173 (37%) were eligible for study and 150 enrolled. A total of 143 patients (95%) completed the trial, 5 (4%) were lost to followup and 2 (1%) withdrew. Baseline characteristics were similar between the groups. Baseline mean ± SD symptomology scores were 19.9 ± 5.5 for the bladder training video and 19.7 ± 6.0 for standard urotherapy. At 3 months the mean symptomology scores for the bladder training video and standard urotherapy were reduced to 14.4 ± 6.5 and 13.8 ± 6.0, respectively (p = 0.54). The mean difference was 0.6 (95% CI -1.4-2.6). The upper 95% CI limit of 2.6 did not exceed the preset 3.5 noninferiority margin. CONCLUSIONS: The bladder training video was not inferior to standard urotherapy in reducing bladder/bowel symptoms in children 5 to 10 years old. The video allows families to have free access to independently review bladder training concepts as often as necessary.

RESUMEN

INTRODUCTION: Postoperative imaging for deceased donor renal transplants is often delayed, as these surgeries occur after-hours. These delays can be critical in identifying immediate complications. To our knowledge, there are no formal training programs for point-of-care ultrasound (POCUS) in this setting; therefore, we aimed to develop and evaluate a feasible and practical POCUS curriculum for the assessment of a renal transplant graft. METHODS: Urology and nephrology transplant physicians completed a three-hour online course, followed by a five-hour hands-on seminar for sonographic scanning. Simulated patients with transplanted kidneys were used. Course material was developed with licensed ultrasound technologists based on Sonography Canada national competency profiles. Pre- and post-course surveys focused on user confidence, while pre- and post-course multiple-choice questionnaires assessed theoretical knowledge. RESULTS: Twelve participants were included, six of whom were urologists. Theoretical knowledge in POCUS improved significantly (p<0.001). Confidence in manipulation of ultrasound controls, Doppler imaging, and POCUS of the transplant kidney also improved (all p<0.001, d>2.0). Participants indicated an increased likelihood of POCUS use in clinical practice and that training should be integrated into a transplant fellowship. CONCLUSIONS: We introduced a novel and guideline-based POCUS curriculum that leveraged local ultrasound educators and found improved theoretical knowledge and skill confidence in our cohort of transplant physicians. This course will serve as the first step toward a validated competency-based training system for POCUS use in the immediate post-renal transplant setting, and likely will be incorporated into the training of the modern transplant physician.

RESUMEN

INTRODUCTION: Accurate diagnostic staging of upper tract urothelial cancer (UTUC) is challenging. Endoscopic staging is limited by its ability to provide adequate sampling of deeper layers of the ureter and renal pelvis. Further ability to accurately predict invasive disease would aid in better selecting the appropriate treatment for patients. We aimed to analyze the ability of preoperative cross-sectional radiologic findings to predict pathologic outcomes, including tumor grade, muscle-invasive disease, and presence of lymphovascular invasion (LVI). METHODS: All patients diagnosed with localized UTUC (cN0M0) who underwent nephroureterectomy between February 2012 and December 2018 in Manitoba, Canada, were identified. Preoperative radiologic characteristics, including the presence and severity of hydronephrosis, as well as tumor location were recorded. Patients' and pathologic characteristics were also recorded. Logistic regression analysis was used to assess the association between radiologic variables and pathologic outcomes at radical surgery. RESULTS: A total of 112 pathology reports of patients with UTUC were obtained. The median age was 70 years (range 50-87), and 58.8% of patients were men. On univariate analysis, ureteric location on computed tomography (odds ratio [OR] 2.240, 95% confidence interval [CU] 1.049- 4.783, p=0.037) and presence of hydronephrosis (OR 2.455, 95% CI 1.094-5.506, p=0.0029) were each independently associated with locally invasive disease (>pT2). No radiologic variables were found to be a predictor of adverse pathology on multivariable analysis. Only the presence of hydronephrosis was associated with high-grade disease on univariate analysis (OR 2.533, 95% CI 1.083-5.931, p=0.032). CONCLUSIONS: Our findings suggest a limited role for cross-sectional imaging in predicting the presence of high-grade disease, LVI, or locally advanced disease in UTUC.

RESUMEN

INTRODUCTION: Robotic surgery is used in the treatment of kidney tumors. We aimed to determine if robotic access was associated with initial choice of management for patients with a clinical stage I kidney mass. METHODS: Patients with a clinical stage I kidney mass were identified from the Canadian Kidney Cancer information system (CKCis) cohort. Sites were classified by year and access to robotic surgery. Associations between robotic access and initial management were determined using logistic regression. Univariable and multivariable analyses were performed, adjusting for tumor size and stage, and presented as relative risks (RR ) or adjusted RR (aRR) and 95% confidence intervals (CI). RESULTS: Overall, 4160 patients were included. Among patients treated with surgery, the proportion of partial nephrectomy compared to radical nephrectomy was significantly higher in robotic sites (77.3% for robotic sites vs. 65.9% for non-robotic sites; RR 1.17, 95% CI 1.12-1.23, p<0.0001; aRR 1.12, 95% CI 1.08-1.17, p<0.0001). Patients receiving partial nephrectomy at sites with robotic access were more likely to receive a minimally invasive approach compared to patients at non-robotic sites (61.4% vs. 50.9%, RR 1.21, 95% CI 1.12-1.30; aRR 1.16, 95% CI 1.08-1.25, p<0.0001). The proportion of patients managed by active surveillance was not significantly different between robotic (405, 16.9%) and non-robotic (258, 14.7%) sites (RR 1.15, 95% CI 0.99-1.32; aRR 0.97, 95% CI 0.84-1.12). CONCLUSIONS: Access to robotic kidney surgery was associated with increased use of partial nephrectomy and minimally invasive partial nephrectomy. Use of active surveillance was similar at robotic and non-robotic institutions. Limitations of this study include lack of data on perioperative complications and cancer recurrence.

RESUMEN

Introduction: Burnout is often misconstrued for stress, whereas it is one of the consequences of stress when not managed prosperously. Stress leads to apprehensiveness, loss of energy, and the primary damage is physical. Whereas, burnout is characterized by disengagement where emotions are blunted thus fostering helplessness and hopelessness leading to detachment and despondence, loss of motivation and ideals with the primary damage being emotional. Objectives: To find out the prevalence and severity of stress and burnout among bank officers in Meerut District and to find the correlation between the two parameters. Methods: Banks were selected by simple random sampling through computer random table method for our study. Further, officer grade bank employees were approached for data collection. A prevalidated seven-point Likert scale Shriom-Melamed Burnout Questionnaire was used for the assessment of burnout. Data were analyzed using appropriate statistical tests by EPI Info and Microsoft Excel 2013. Result: 19.7% bank officers have pathological burnout followed by 55.1% of bank officers who are at the brink of developing burnout. Severe stress was found only among 7.9% bank officers, whereas burnout was present in 19.4%. A positive correlation was found between stress and burnout. Conclusion: It was found that stress and job burnout are linked but do not entirely overlap, with individuals having a high risk of job burnout experiencing only moderate stress. Therefore, perceived stress cannot be taken as the only indicator of risk of burnout.

RESUMEN

OBJECTIVE: To assess the knowledge about hepatitis B among the medical, dental and nursing students of first year in Subharti University, a private medical university of North India. METHODS: A cross sectional institutional study was conducted among the first year students of medical, dental and nursing colleges of Subharti University. The total subjects studied were 250. Data was collected when the student came up for hepatitis B vaccination in the Department of Community Medicine. Data was entered in MS Excel and analyzed using Epi Info for Windows. Bivariate analysis using Chi-square test was applied. RESULTS: Overall, 83.32% of the study subjects had heard of hepatitis B. Only 42% knew that virus is a cause of hepatitis B. Awareness of mother to child transmission of hepatitis B was present in only 12% of the study subjects. Unsafe blood transfusion as a risk factor of hepatitis B was known by 35.2%, whereas, prevalence of knowledge regarding reused needles and unsafe sex as risk factors was lesser. Forty-four percent of the study subjects were not aware of vaccination against hepatitis B. There was a significant difference in the proportion of students of the different faculties about the correct knowledge about hepatitis B. CONCLUSION: The knowledge about hepatitis B was very low among the students entering in the medical, dental and nursing profession. This highlights the importance of informed and evidence based education programmes among the students of these healthcare professions.

RESUMEN

INTRODUCTION: It is often perceived that the presence of a distinct surgical personality plays an important role in predicting success in their surgical career. This study compares the personality profiles, perceived stress, and learning styles of surgical and nonsurgical residents. AIM: The aim of this study is to examine the differences in personality traits, learning style preferences, and perceived stress among surgical and nonsurgical residents. SETTING AND DESIGN: A cross-sectional study was conducted comparing surgical and non-surgical residents in a tertiary care teaching hospital. MATERIALS AND METHODS: The 50-item International Personality Item Pool Big- Five Factor Marker questionnaire was used to score 5 personality domains. The 24-item Learning Style Inventory Questionnaire was used to determine the preferential learning styles (visual, auditory, or tactile). The Perceived Stress Scale was administered to assess the perception of stress in the residents. STATISTICAL ANALYSIS: t-test and chi-square test were done for statistical analysis. RESULTS: A statistically significant difference was found in learning style preferences with visual (14.78 ± 3.73 vs. 7.4 ± 2.25) and kinesthetic styles being (13.84 ± 4.37 vs. 6.96 ± 1.47) preferred by surgical residents whereas auditory style was preferred by nonsurgical residents (P < 0.05). Surgical residents scored higher in extraversion (P = 0.00), conscientiousness (P = 0.00), and openness to experience (P = 0.00) which was statistically significant. Nonsurgical residents were found to have a higher perception of stress which was statistically significant (13.40 ± 7.10 vs. 21.12 ± 7.52) (P = 0.01). CONCLUSION: The significant trait variance supports the concept of surgical personality.

RESUMEN

In this study, the transmissibility estimation of novel coronavirus (COVID-19) has been presented using the generalized fractional-order calculus (FOC) based extended Kalman filter (EKF) and wavelet transform (WT) methods. Initially, the state-space representation for the bats-hosts-reservoir-people (BHRP) model is obtained using a set of fractional order differential equations for the susceptible-exposed-infectious-recovered (SEIR) model. Afterward, the EKF and Kronecker product based WT methods have been applied to the discrete vector representation of the BHRP model. The main advantage of using EKF in this system is that it considers both the process and the measurement noise, which gives better accuracy and probable states, which are the Markovian (processes). The importance of proposed models lies in the fact that these models can accommodate conventional EKF and WT methods as their special cases. Further, we have compared the estimated number of contagious people and recovered people with the actual number of infectious people and recovered people in India and China.

RESUMEN

AIM: The aim of this study was to evaluate the efficacy of various routinely used analgesics in the management of pulpal pain preoperatively. MATERIALS AND METHODS: A total of 150 patients were randomly selected and divided into five groups each. At initial visit, a self-administered questionnaire was given, and patients were asked to mark on the Visual Analog Scale (VAS) indicating severity of pain at that moment which is taken as a pretreatment VAS score. Group I patients received aceclofenac + paracetamol, Group II: ketorolac tromethamine, Group III: lornoxicam + paracetamol, Group IV: tramadol + paracetamol, and Group V: paracetamol. All the patients are requested to record their pain levels at 4 h, 6 h, 8 h, 24 h, and 48 h by means of VAS scores before and after treatment. RESULTS: There was no significant decrease in frequency of pain when compared in the first three groups, whereas in Group III and Group IV, the patients experienced an effective reduction in pain because of sustained releasing ability of these drugs. Overall, there was no statistically significant differences among all the groups. CONCLUSION: This study suggests that there was no significant difference in reduction of pain preoperatively. However, lornoxicam + paracetamol and tramadol + paracetamol were effective because of their sustained releasing ability. Ketorolac was effective to reduce the pain for shorter duration. Paracetamol can be advised in compromised patients where safety is concerned.

RESUMEN

PURPOSE: The prognostic significance of level of venous tumor thrombus (VTT) extension in patients with non-metastatic renal cell carcinoma (RCC) has been controversial. The aim of this study was to examine the prognostic significance of VTT extent in patients who underwent surgery for non-metastatic RCC. MATERIALS AND METHODS: The Canadian Kidney Cancer information system database was used to identify patients who underwent surgery for non-metastatic RCC and VTT from January 2011 to December 2019. Association between VTT level and recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS) was examined. Univariable and multivariable analyses were performed to estimate predictors of survival. RESULTS: Out of 6,340 patients during the study period, 228 patients (3.6%) had VTT. VTT was level 0 in 84 (37%), level I to II in 112 (49%), and level III to IV in 33 (14%) patients as per the Mayo Clinic classification. Median age was 65.4 years (interquartile range [IQR] 57.6-72.2) and 169 (74.1%) were male. After a median follow-up of 21.2 months, VTT level did not significantly impact the RFS, CSS, or OS. For VTT level 0, I to II, and III to IV, there was no significant difference in estimated 5-year RFS (31%, 23%, and 30.5%; P > 0.05), CSS (70%, 69%, and 55%; P > 0.05) and OS (64%, 66%, and 50%; P > 0.05). Adjusting for known prognostic factors, thrombus level was not associated with risk of recurrence or death. CONCLUSION: In a large, multi-institutional cohort of patients undergoing surgery for non-metastatic RCC with tumor thrombus, thrombus extent was not independently associated with recurrence or death.

RESUMEN

INTRODUCTION: The impact of paraneoplastic syndromes (PNS) on survival in patients with renal cell carcinoma (RCC) is uncertain. This study was conducted to analyze the association of PNS with recurrence and survival of patients with non-metastatic RCC undergoing nephrectomy. METHODS: The Canadian Kidney Cancer information system is a multi-institutional cohort of patients started in January 2011. Patients with nephrectomy for non-metastatic RCC were identified. PNS included anemia, polycythemia, hypercalcemia, and weight loss. Associations between PNS and recurrence or death were assessed using Kaplan-Meier curves and multivariable analysis. RESULTS: Of 4337 patients, 1314 (30.3%) had evidence of one or more PNS. Patients with PNS were older, had higher comorbidity, and had more advanced clinical and pathological tumor characteristics as compared to patients without PNS (all p<0.05). Kaplan-Meier five-year estimated recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were significantly worse in patients with PNS (63.7%, 84.3%, and 79.6%, respectively, for patients with PNS vs. 73.9%, 90.8%, and 90.1%, respectively, for patients without PNS, all p<0.005). On univariable analysis, presence of PNS increased risk of recurrence (hazard ratio [HR] 1.67, 95% confidence interval [CI] 1.48-1.90, p<0.0001) and cancer-related death (HR 1.85, 95% CI 1.34-2.54, p=0.0002). Adjusting for known prognostic factors, PNS was not associated with recurrence or survival. CONCLUSIONS: In non-metastatic RCC patients undergoing surgery, presence of PNS is associated with older age, higher Charlson comorbidity index score, advanced tumor stage, and aggressive tumor histology. Following surgery, baseline PNS is not strongly independently associated with recurrence or death.

RESUMEN

BACKGROUND: Bipolar disorder is a disabling psychiatric disorder. The existing literature suggests about 41% of patients to be nonadherent. Nonadherence leads to relapses, delay in recovery besides higher inpatient care cost as well as higher global cost of the disease. Nonadherence in bipolar affective disorder (BPAD) is a complex phenomenon, its critical determinants are yet to be identified with certainty. AIMS: This study aims to assess the prevalence of nonadherence in BPAD and to delineate the factors associated with it. METHODS: Medical records were reviewed in this study from 2005 to 2019 at a medical college in Kerala. Patients who were diagnosed with BPAD according to International Classification of Diseases 10 and who were needing or opting for prophylaxis were included. Patients who were not taking medications for at least 1 week were termed as nonadherent. We included 150 participants in our study. RESULTS: To test the statistical significance of the association of categorical variables between H/O of adherence and nonadherence, Chi-square test was used. In the sample, 82.7% had at least 1 week of history of noncompliance in the past. The most common reason was poor understanding of illness by the family (56%) followed by a negative aspect of the patient toward the drug (20%). CONCLUSION: Therefore, this study concludes that though majority of the patients have a history of nonadherence of at least 1 week on long-term follow-up, it was seen that majority of the patients were more than 80% adherent to medications.

RESUMEN

BACKGROUND AND AIMS: The impact of altered cholesterol metabolism on post-prandial lipids in Indians with hypothyroidism is not known. This study evaluated the impact of overt primary hypothyroidism (OPH) and subclinical hypothyroidism (ScH) on post-prandial lipids after a standardised, carbohydrate-rich, mixed meal. METHODS: Endocrinology outpatients were screened for possible inclusion into the study. Patients >18 years of age with hypothyroidism who were not taking levothyroxine and who did not present with any comorbidities underwent biochemical evaluation following a carbohydrate-rich, mixed meal. Assessments included total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), triglycerides, lipoprotein-A (Lp-A), apolipoprotein-A1 (apo-A1), apolipoprotein-B (apo-B), insulin and fasting glucose. Assessments were carried out 1 hour, 2 hours and 4 hours after the meal. Patients were compared against healthy matched controls recruited from healthcare professionals in the hospital (asymptomatic and apparently healthy nursing staff, reception staff and ward staff). RESULTS: Data from 194 patients (161 with ScH and 33 with OPH) and 40 euthyroid controls were analysed. Anthropometry, body mass index, glycaemia and insulin resistance were comparable among patients with OPH and ScH, and controls. LDL-C and Lp-A were significantly higher in those with OPH, compared with ScH and controls, at baseline, 1 hour, 2 hours and 4 hours after mixed meal consumption (all p<0.05). There was progressive and similar decline in post-prandial TC, LDL-C and Lp-A in all three groups. Triglycerides were similar among the OPH, ScH and control groups, both in fasting and post-prandial state, with a progressive and similar increase in post-prandial triglycerides in all three groups. CONCLUSION: This study demonstrated that severity of hypothyroidism had no impact on post-prandial TC, LDL-C and Lp-A. In addition, hypothyroidism had no impact on post-prandial triglycerides. Therefore, we conclude that lipid profile can be reliably estimated in a non-fasting state in individuals with ScH and OPH.

RESUMEN

The corpus callosum (CC) is the main commissure connecting the cerebral hemispheres. Previous evidence suggests the involvement of the CC in the pathophysiology of autism. However, most studies examined the mid-sagittal area and investigations applying novel methods are warranted. The goal of this investigation is to apply a volumetric method to examine the size of the CC in autism and to identify any association with clinical features. An MRI-based morphometric study of the total CC volume and its seven subdivisions was conducted and involved 22 children with autism (age range 8.1-12.7 years) and 23 healthy, age-matched controls. Reductions in the total volume of the CC and several of its subdivisions were found in the autism sample. Associations were observed between CC structures and clinical features including social deficits, repetitive behaviors, and sensory abnormalities. Volumetric alterations of the CC observed in this investigation are consistent with midsagittal area tracings of decreased CC size in autism. These findings support the aberrant connectivity hypothesis with possible decrease in interhemispheric communications.
