RESUMO

African American (AA) kidney transplant recipients (KTRs) have poor outcomes, which may in-part be due to tacrolimus (TAC) sub-optimal immunosuppression. We previously determined the common genetic regulators of TAC pharmacokinetics in AAs which were CYP3A5 *3, *6, and *7. To identify low-frequency variants that impact TAC pharmacokinetics, we used extreme phenotype sampling and compared individuals with extreme high (n=58) and low (n=60) TAC troughs (N=515 AA KTRs). Targeted next generation sequencing was conducted in these two groups. Median TAC troughs in the high group were 7.7 ng/ml compared with 6.3 ng/ml in the low group, despite lower daily doses of 5 versus 12mg, respectively. Of 34,542 identified variants across 99 genes, 1,406 variants were suggestively associated with TAC troughs in univariate models (p-value <0.05), however none were significant after multiple testing correction. We suggest future studies investigate additional sources of TAC pharmacokinetic variability such as drug-drug-gene interactions and pharmacomicrobiome.

RESUMO

Subgenome dominance has been reported in diverse allopolyploid species, where genes from one subgenome are preferentially retained and are more highly expressed than those from other subgenome(s). However, the molecular mechanisms responsible for subgenome dominance remain poorly understood. Here, we develop genome-wide map of accessible chromatin regions (ACRs) in cultivated strawberry (2n = 8x = 56, with A, B, C, D subgenomes). Each ACR is identified as an MNase hypersensitive site (MHS). We discover that the dominant subgenome A contains a greater number of total MHSs and MHS per gene than the submissive B/C/D subgenomes. Subgenome A suffers fewer losses of MHS-related DNA sequences and fewer MHS fragmentations caused by insertions of transposable elements. We also discover that genes and MHSs related to stress response have been preferentially retained in subgenome A. We conclude that preservation of genes and their cognate ACRs, especially those related to stress responses, play a major role in the establishment of subgenome dominance in octoploid strawberry.

RESUMO

Introduction: Indocyanine green (ICG) angiography is the 'real-time intraoperative imaging' technique used to reduce the chances of hypoparathyroidism in post-thyroidectomy patients. In our study, the authors predicted the risk of early post-thyroidectomy hypocalcemia by intraoperative evaluation of parathyroid gland perfusion by ICG angiography. Materials and methods: In patients who underwent total thyroidectomy, ICG angiography was done using the SPY PHI imaging system (Stryker). Post-thyroid specimen removal, scoring of parathyroids was done in spy contrast mode. All 4 or <4 visualized parathyroids were scored for vascularity with the highest score of 8. Serum ionized calcium was done 6 h postsurgery and on the morning and evening of postoperative days 1 and 2. Calcium supplements were given to only those who developed clinical or severe biochemical hypocalcemia. Results: Out of 60, postoperative hypocalcemia was noted in 41 patients. Total ICG score ≤5 was seen in 34 patients, out of which 28 developed postoperative hypocalcemia showing PPV 82.3% and diagnostic accuracy of 68.3% while iPTH (4.28 pmol/l) showed PPV 76.7 and diagnostic accuracy 70 %. In eight patients, none of the glands was scored as 2 (White) and all these patients developed hypocalcemia requiring calcium infusion. Conclusion: The absence of visualization of at least 1 well-perfused (score 2) gland on ICG angiography is highly predictive of hypocalcemia and the majority of patients with total ICG score ≤5 developed hypocalcemia in the immediate postoperative period. ICG is a good predictor of the absence of hypoparathyroidism after thyroidectomy and is comparable to iPTH in the prediction of post-thyroidectomy hypocalcemia.

RESUMO

BACKGROUND: Pediatric endocrine disorders requiring surgical intervention are rare and so are experienced surgeons dealing with these. The aim of the current study was to investigate disease profile and perioperative outcome of pediatric patients with surgical endocrine disorders in an endocrine surgery unit. METHODS: This retrospective study (Sep 1989-Aug 2019) consisted of pediatric endocrine surgery patients (<18 years) who were managed by a team of pediatric endocrinologists and endocrine surgeons at our center. Patients were divided into three cohorts consisting of a decade each. Clinico-pathologic variables, perioperative events operative and follow-up details were recorded. RESULTS: A total of 332 children were included and their mean age was 14.6 ± 3.9 years (M:F = 1:1.6). Thyroid disorders were most prevalent (59.8%), followed by adrenal (28.2%), parathyroid (10.4%), and pancreas (1.5%). Incidence of benign, malignant, and congenital/developmental disorders were 65.4, 28.1 and 8.3, respectively. Familial association was observed in 8.9% children, which is highest among pheochromocytoma patients. Overall, 201 thyroidectomies + associated procedures, 35 parathyroidectomies, 96 adrenal and paraganglioma resections, and 5 pancreatic procedures were performed. Median hospital stay was 5.6 ± 4.1 days. The number of cases increased significantly over 3 decades. Clinical profile and outcome did not vary except for significant decrease in incidence of malignant pathology (p = 0.04) and increase in VHL cases (p = 0.04) in the last decade though overall increase in familial cases was nonsignificant (p = 0.11). No perioperative mortality was observed except for 3% after adrenalectomy. CONCLUSION: A team of dedicated endocrine surgeons and pediatric endocrinologists is effective in management of pediatric endocrine surgery.

RESUMO

OBJECTIVE: To describe determinants of persisting humoral and cellular immune response to the second COVID-19 vaccination among patients with myeloma. METHODS: This is a prospective, observational study utilising the RUDYstudy.org platform. Participants reported their second and third COVID-19 vaccination dates. Myeloma patients had an Anti-S antibody level sample taken at least 21 days after their second vaccination and a repeat sample before their third vaccination. RESULTS: 60 patients provided samples at least 3 weeks (median 57.5 days) after their second vaccination and before their third vaccination (median 176.0 days after second vaccine dose). Low Anti-S antibody levels (<50 IU/mL) doubled during this interval (p = .023) and, in the 47 participants with T-spot data, there was a 25% increase negative T-spot tests (p = .008). Low anti-S antibody levels prior to the third vaccination were predicted by lower Anti-S antibody level and negative T-spot status after the second vaccine. Independent determinants of a negative T-spot included increasing age, previous COVID infection, high CD4 count and lower percentage change in Anti-S antibody levels. CONCLUSIONS: Negative T-spot results predict low Anti-S antibody levels (<50 IU/mL) following a second COVID-19 vaccination and a number of biomarkers predict T cell responses in myeloma patients.

RESUMO

INTRODUCTION: Noise in the operating room is an ongoing problem that impacts the outcome of any surgery. Noise as a stressor can produce a startling reaction and activate the fight or flight response of the autonomic and endocrine systems. The psychobiology of stress as assessed by salivary cortisol level is a sensitive measure of allostatic load. This study aims to correlate, both subjectively and objectively, the salivary cortisol levels of the surgeon with noise level measurement in an endocrine surgery operating room (OR). MATERIALS AND METHODS: A prospective observational study was conducted in the Endocrine surgery OR of a tertiary care center. We recorded the noise from the shifting in of patients in the OR to shifting out using a digital sound level meter. The operating surgeon (S) provided two salivary cortisol samples (normal salivary cortisol <5 nmol/L), one baseline and another after the procedure. The questionnaire for the assessment of distraction during thyroidectomy was filled in by the S at the end of the procedure. Salivary cortisol levels were analyzed using SLV-4635 (formerly SLV-2930) DRG Instruments GmbH German using the ELISA technique. Statistical analysis was performed using SPSS 22.0. RESULTS: A total of 37 procedures with 74 salivary cortisol samples and 259 questionnaire responses from S were analyzed. All patients with only benign FNAC were operated upon (64.9% colloid). Mean TSH levels were 3.5 ± 6.7 mIU/L. The majority had a solitary thyroid nodule (STN) (25/37, 67.6%). Nineteen patients (51.3%) underwent open hemithyroidectomy, 10 patients total thyroidectomy, and eight patients endoscopic hemithyroidectomy. The mean noise level in the OR was 70 db. The maximum and minimum noise level in the OR was 90.06 and 51.81 dB, respectively. A total of 74 salivary cortisol samples from the S were collected (baseline and post-noise exposure) and mean cortisol levels were recorded. The surgeon was more significantly affected by surrounding noise, especially during critical phases 3 of surgery, mainly, RLN dissection and parathyroid dissection as recorded by their responses in the questionnaire (p = 0.003). The maximum value of post-operative salivary cortisol of surgeon was recorded as 23. 48 ng/mL and the minimum value recorded was 0.49 ng/mL. The difference in baseline cortisol and post-noise exposure cortisol levels of surgeon was found to be significant (p < 0.001). Maximum and mean noise levels were significantly associated with post-noise exposure salivary cortisol elevation in the surgeon (p = 0.032 and 0.014, respectively). The noise levels during RLN dissection were borderline significant with the post-noise exposure salivary cortisol of the surgeon (p = 0.055). CONCLUSION: Our research is the first such study which has been done to assess noise levels and their effect on thyroidectomy using objective salivary cortisol measurement. It challenges the misconstrued notion that visceral surgeries requiring lesser instruments are not associated with noise-related stress. Noise is a major distraction and the effect of long-term effect on the entire surgical team needs to be studied.

RESUMO

Teleost fishes, which are the largest and most diverse group of living vertebrates, have a rich history of ancient and recent polyploidy. Previous studies of allotetraploid common carp and goldfish (cyprinids) reported a dominant subgenome, which is more expressed and exhibits biased gene retention. However, the underlying mechanisms contributing to observed 'subgenome dominance' remains poorly understood. Here we report high-quality genomes of twenty-one cyprinids to investigate the origin and subsequent subgenome evolution patterns following three independent allopolyploidy events. We identify the closest extant relatives of the diploid progenitor species, investigate genetic and epigenetic differences among subgenomes, and conclude that observed subgenome dominance patterns are likely due to a combination of maternal dominance and transposable element densities in each polyploid. These findings provide an important foundation to understanding subgenome dominance patterns observed in teleost fishes, and ultimately the role of polyploidy in contributing to evolutionary innovations.

RESUMO

Background: Breast self-examination (BSE) plays an important role in the early diagnosis of breast cancer in India owing to the stigma attached to cancer. The authors compared the efficacies of animation video versus simulation techniques in BSE. Methods: Women with no previous history of conditions affecting the breasts were included in this prospective observational study and divided into an animation or simulation arm. The latter was further divided into three subgroups as per the simulation models used : the German (Delta Healthcare), British (Health Edco), and Indian (low-cost, validated) models used for teaching BSE. The hybrid animation video had a 9 min runtime with a lecture on BSE and a virtual character performing BSE. In both the arms, participants filled in a validated modified patient satisfaction questionnaire. Results: A total of 500 women participated. The mean age of the participants in the animation video arm was 20.21±3.88 years and 19.34±2.27, 22.94±9.6, and 18.97±1.31(20.41±5.99) years in the Indian, German, and British simulation models arm, respectively. The age difference between the two arms was statistically significant (P<0.05). Both animation video and simulation models were found to be useful by the participants. The participants' response to animation video being a better organized tool for learning BSE was statistically significant (90.48±7.98 vs. 84.02±15.09 P≤0.001) when compared to simulation models. The younger women (≤20 years) found these tools significantly more useful than those aged >20 years. Conclusions: All models had good efficiency and utility as learning tools for BSE. However, large studies in BSE set up with combination models are needed.

RESUMO

Monoclonal antibodies have been successfully utilized in a variety of animal models to treat auto-immune illnesses for a long time. Immune system responses will either be less active or more active depending on how the immune system is operating abnormally. Immune system hypoactivity reduces the body's capacity to fight off various invading pathogens, whereas immune system hyperactivity causes the body to attack and kill its own tissues and cells. For maximal patient compliance, we will concentrate on a variety of antibody therapies in this study to treat Type 1 diabetes (an autoimmune condition). T cells are responsible for the auto-immune condition known as T1D, which causes irregularities in the function of ß-cells in the pancreas. As a result, for the treatment and prevention of T1D, immunotherapies that selectively restore continuous beta cell-specific self-tolerance are needed. Utilizing monoclonal antibodies is one way to specifically target immune cell populations responsible for the auto-immune-driven disease (mAb). Numerous mAbs have demonstrated clinical safety and varied degrees of success in modulating autoimmunity, including T1D. A targeted cell population is exhausted by mAb treatments, regardless of antigenic specificity. One drawback of this treatment is the loss of obtained protective immunity. Immune effector cell function is regulated by nondepleting monoclonal antibodies (mAb). The antigen-focused new drug delivery system is made possible by the adaptability of mAbs. For the treatment of T1D and T cell-mediated autoimmunity, different existing and potential mAb therapy methods are described in this article.

RESUMO

Introduction Cavitary lung disease has a wide range of differential diagnoses, which include both benign and malignant lesions. Imaging differentiation of benign from malignant cavitary lesions has always been a challenge due to overlapping imaging findings. The present study describes the most accurate multidetector computed tomography (MDCT) findings that could help in differentiating benign from malignant conditions in correlation with the histopathological reports. Methods This retrospective study was carried out on diagnosed cases of cavitary lung lesions on MDCT from January 2022 to February 2023. We evaluated the number of cavitary lung lesions, their location with respect to lung segment/lobe, the maximum diameter of the largest lesion, the maximum wall thickness of the largest cavity, and additional findings associated with these lesions. Measurements of the maximum wall thickness were plotted on a graph. Statistical analysis was done, and a receiver operating characteristic curve (ROC) was calculated to find the accurate cut-off wall thickness for malignant and non-malignant lesions. These findings were then correlated with the histopathological report. Results A review of the MDCT scans of 47 patients was done; 30 (63.8%) of those were male with a mean age of 47.93±14.68 (SD) years while 17 (36.2%) were female with a mean age of 52.53 ±18.38 (SD) years. Out of 47 patients, 27 (57.4%) had benign lesions and 20 (42.5%) had malignant lesions. Significant differences (p<0.05) were found between benign and malignant lesions while comparing the averages of maximum wall thickness (8.1 mm and 14.5 mm, respectively) and the irregular inner margin of the largest cavitary lesions. The presence of consolidation and centrilobular nodules correlated significantly (p<0.05) with the benign nature of cavitary lung lesions. The maximum cut-off wall thickness was <6 mm and >17 mm for the differentiation of benign from malignant lung lesions, respectively. Conclusions The maximum wall thickness and irregular inner margin of cavitary lung lesions was a good indicator for the differentiation of benign and malignant etiologies on MDCT while consolidation and centrilobular nodules favoured the benign etiology more.

RESUMO

BACKGROUND: Myelolipomas are benign tumors usually found in adrenal glands. They can also be found extra-adrenally, either in 1 or multiple locations. Perinephric transplant myelolipoma has rarely been reported in the English literature. There's only been 1 instance of such a case reported in a kidney transplant patient, which was found on the explanted kidney. We report a case involving an asymptomatic patient with an ill-defined perinephric transplant mass. METHODS: The mass was then identified as myelolipoma on biopsy. The patient was then managed conservatively with serial imaging and laboratory testing. RESULTS: At the time of our report, the patient continues to have stable renal function and is doing well 24 months after the mass was first identified. CONCLUSIONS: We report the first case of perinephric transplant myelolipoma in a patient with ongoing stable renal allograft function. Based on our case report, we recommended that conservative management with serial imaging and routine testing be considered for patients with perinephric transplant myelolipoma.

RESUMO

BACKGROUND BK infections have been observed more frequently among people who are rapid metabolizers. The tacrolimus c/d ratio identifies rapid metabolizers after transplantation. Envarsus has a lower peak drug level exposure than tacrolimus and is more pronounced in rapid metabolizers. This study hypothesized that less exposure to high tacrolimus levels through use of Envarsus would reduce the incidence of BK infections. MATERIAL AND METHODS This study prospectively converted 43 consecutive kidney transplant recipients (identified as rapid metabolizers by c/d ratio of.

RESUMO

BACKGROUND: Margin assessment is an essential component of breast conservation surgery (BCS). Re-excision of infiltrated margin(s) detected on paraffin section histology (PSH) needs reoperation, adding time, inconvenience and cost. Intra-operative assessment of margins using frozen section histology (IFSH) can potentially obviate need for re-operation, thus facilitating one-step oncologically complete BCS. METHODS: IFSH and PSH reports of consecutive patients undergoing BCS (2010-2020) were reviewed. Accuracy and cost-efficacy of IFSH were assessed, considering PSH as gold standard. Cost of achieving oncologically complete BCS in whole cohort with IFSH (Scenario-A) was calculated and compared using appropriate statistical tests, with hospital costs for the cohort in a hypothetical Scenario-B, where IFSH was presumed not to have been used and all patients with infiltrated margin(s) on PSH would have been re-operated. RESULTS: Of the 367 patients screened, 39 were excluded due to incomplete IFSH data. Of 328 patients analyzed, 59 (18%) had one or more margins were reported infiltrated on IFSH, managed by re-excision or mastectomy in the same sitting, thus avoiding a reoperation. Additional 8 (2.4%) had involved margins on PSH (False negative IFSH). Significantly higher number of reoperations (p < 0.001) would have been needed in scenario-B. Average cost of the first operation with use of IFSH was Indian Rupees (INR) 25791 which included INR660 as IFSH cost. The average cost of reoperation was INR23724 which could be avoided in 59 (18%) by use of IFSH. The average cost per patient to achieve oncologically complete surgery in scenario A utilizing IFSH was significantly lower (p = 0.001) by INR3101 (11.7%), c.w. that in scenario B. Significant cost-saving with IFSH was maintained in cost-efficacy analysis undertaken with various higher and lower costs assumptions. CONCLUSIONS: Use of IFSH facilitates one-step oncologically complete BCS in majority of patients and results in considerable cost saving, resulting in avoidance of reoperations, besides preventing patient anxiety and delay in adjuvant treatment.

RESUMO

Background In India, a significant number of newborns die each year, with Madhya Pradesh having the highest neonatal mortality rate. However, there is a lack of information on factors that can predict neonatal mortality. Objective This study aimed to examine the factors influencing neonatal mortality among neonates admitted to a tertiary care centre's special newborn care unit (SNCU). Methods This retrospective record-based observational study was done at a tertiary care centre, where data from the special newborn care unit (SNCU) from 1st January 2021 to 31st December 2021 was used. We included data of all newborns who were treated in SNCU during the said period and excluded those who got referred or left against medical advice. We abstracted data on age at admission, gender, category, maturity status, birth weight, place of delivery, mode of transport, type of admission, indication of admission, duration of stay and outcome. Qualitative variables were described using frequency and percentage. The chi-square test was used to find out the association of different variables with the outcome, while multivariate logistic regression was conducted to identify risk factors of neonatal mortality. A p-value of <0.05 was considered significant. Results We finalized data of 1052 neonates for analysis. Among them, 846 neonates were successfully discharged while 206 neonates were deceased. The major cause of admission was perinatal asphyxia followed by prematurity. The major cause of mortality in this study was sepsis followed by respiratory distress syndrome, birth asphyxia, and prematurity. Mortality of neonates was significantly associated with maturity status, birth weight, place of delivery, age during admission and duration of stay. Prematurity (OR=3.762, 95% CI:1.93-7.33), birth weight 1000-1499g (OR=4.78, 95% CI:2.21-10.32), birth weight <1000g (OR=25.11, 95% CI:5.71-110.24), age at admission <1-day (OR=2.312, 95% CI:1.03-5.19), duration of stay 1-3-days (OR=12.98, 95% CI:7.48-22.52) and <1-day (OR=1271.88, 95% CI:121.39-13325.69) were significant predictors of mortality in our study. Conclusion Our study emphasizes monitoring and addressing risk factors like maturity status, birth weight, and age at admission to reduce neonatal mortality, with a focus on early management of preterm births and low birth weight.

RESUMO

Background and Aims: Postoperative analgesia for Total Knee Arthroplasty (TKA) is paramount for early mobilisation and rehabilitation. The newer motor sparing peripheral nerve blocks for analgesia for TKA are 4 in 1 block, modified 4 in 1 block, infiltration between popliteal artery and capsule of the knee (IPACK) block along with adductor canal block (ACB). We hypothesised that Modified 4 in 1 block is as efficient as the already proven technique of combined IPACK and ACB in providing post-operative analgesia to the patients of TKA. Methods: Seventy patients fulfilling the inclusion criteria posted for TKA surgery were randomised into two groups: Modified 4 in 1 block group (Group - M) and combined IPACK + ACB group (Group - I). After thorough preoperative evaluation and with mimimum standard monitoring the patients received sub-arachnoid block followed by the desired peripheral nerve block as per the group. After the surgery the visual analog scale (VAS) pain score was compared at 3, 6, 12, 24 hours postoperatively and tabulated. Results: The mean pain scores between both the groups was comparable at 3 hours, 6 hours and 24 hours. But at 12 hours after the surgery, VAS was less in Group-M in comparison to Group-I, Haemodynamic parameters were comparable between both the groups. None of the patients in both the groups showed any complications like muscle weakness in the post-operative period. Conclusion: Modified 4 in 1 block is a new and novel technique for the TKA surgeries and is comparable with already established combined IPACK+ACB technique for providing adequate postoperative analgesia after TKA.

RESUMO

Haematology patients contracting SARS-CoV-2 were identified at the start of the pandemic to be at higher risk of death or of persistent symptoms (post-COVID-19 syndrome). As variants with altered pathogenicity have emerged, uncertainty remains around how that risk has changed. We prospectively set up a dedicated post-COVID-19 clinic to monitor haematology patients infected with COVID-19 from the start of the pandemic. In total, 128 patients were identified and telephone interviews were conducted with 94 of 95 survivors. Ninety-day mortality attributed to COVID-19 has fallen sequentially from 42% for the Original and Alpha strains to 9% and to 2% for the Delta and Omicron variants respectively. Furthermore, the risk of post-COVID-19 syndrome in survivors has fallen from 46% for the Original or Alpha strains to 35% for Delta and 14% for the Omicron strain. Since vaccine uptake has been nearly universal in haematology patients, it is not possible to determine whether improved outcomes reflect the reduced pathogenicity of the virus, or widespread vaccine deployment. Whilst mortality and morbidity remain higher in haematology patients than in the general population, our data suggest that the absolute risks are now significantly lower. Given this trend, we believe clinicians should initiate conversations about risk with their patients on whether to maintain any self-imposed social isolation.

RESUMO

BACKGROUND: Tumor neo-angiogenesis plays an important role in the development and growth of breast cancers, but its detection by imaging is challenging. A novel microvascular imaging (MVI) technique, Angio-PLUS, promises to overcome the limitations of color Doppler (CD) in detecting low-velocity flow and small diameter vessels. PURPOSE: To determine the utility of the Angio-PLUS technique for detecting blood flow in breast masses and compare it with CD for differentiating benign from malignant masses. MATERIAL AND METHODS: A total of 79 consecutive women with breast masses were prospectively evaluated using CD and Angio-PLUS techniques, and biopsied as per BI-RADS recommendations. Vascular imaging scores were assigned using three factors (number, morphology, and distribution) and vascular patterns were divided into five groups: internal-dot-spot, external-dot-spot, marginal, radial, and mesh patterns. The independent samples t-test, Mann-Whitney U test, Wilcoxon signed rank test, or Fisher's exact test were used to compare the two groups as appropriate. Area under the receiver operating characteristic (ROC) curve (AUC) methods were used to assess diagnostic accuracy. RESULTS: Vascular scores were significantly higher on Angio-PLUS than CD (median=11, [IQR=9-13] vs. 5 [IQR=3-9], P < 0.001). Malignant masses had higher vascular scores than benign masses on Angio-PLUS (P < 0.001). AUC was 80% (95% CI=70.3-89.7; P < 0.001) for Angio-PLUS and 51.9% for CD. Using Angio-PLUS at a cutoff value of ≥9.5, sensitivity was 80% and specificity was 66.7%. Vascular pattern descriptors on AP showed good correlation with histopathological results (PPV mesh 95.5%, radial 96.9%, and NPV of marginal orientation 90.5%). CONCLUSION: Angio-PLUS was more sensitive in detecting vascularity and superior in differentiating benign from malignant masses compared to CD. Vascular pattern descriptors on Angio-PLUS were useful.
