Molecular subtypes of invasive breast carcinoma of no special type, their correlation with histopathological features, Ki 67 index and tumor budding: A retrospective comparative study

Context: Tumor budding (TB), poorly differentiated clusters (PDCs), and Ki 67 index are proven adverse prognostic factors in breast carcinoma. Though the relation of Ki 67 index with molecular subtypes of breast carcinoma have been extensively studied, there is very limited information on the role of TB and PDCs. Aims: To grade TB, PDCs, and Ki 67 index and assess histological features and relationship of all these with molecular subtypes of invasive breast carcinoma of no special type. Methods and Material: Retrospective study of 148 cases from 1/1/2019 to 30/12/2019. Division of molecular groups – Luminal A, Luminal B, Her2 neu positive, and triple-negative breast carcinomas (TNBC), and Ki 67 index grades based on St Gallen criteria, intratumoral and peritumoral TB and PDC grades as per the International Tumor Budding Consensus Conference (ITBCC) criteria for colon and correlation between these and other histological features with the molecular subtypes were done. Statistical Analysis: Chi-square test, univariate and multivariate logistic regression models were used. Results: Significant correlation was seen between TB and lymphovascular emboli, Luminal B tumors with high-grade TB and PDCs, Her 2 neu positive and TNBC tumors with low-grade TB, circumscribed tumor margins, tumor necrosis, and Luminal B, Her 2 neu positive and TNBC tumors with larger tumor size and high nuclear grades.Conclusions: TB and PDCs are useful in the prognostication of Luminal A and B tumors when the Ki 67 index values are low/intermediate. Her 2 neu positive and TNBC tumors have a high nuclear grade with necrosis and no association with TB or PDCs.

Feto-maternal haemorrhage: a review after and a case report

Feto-maternal haemorrhage is the transmission of fetal blood cells to the maternal blood stream. It is quite common in small volumes- occurring in most pregnancies. Large volumes of feto-maternal haemorrhage can have serious consequences. Some risk factors are identified, but they are not always present. Decreased perception of fetal movements is most important clinical sign, together with a pathological NST. Prompt diagnosis and immediate obstetric care is fundamental, as serious risk to the fetus might result from this condition. Author described the case report of 35 years old G3P1L1A1 with 37 weeks 5 days pregnancy, who came in outpatient department with reduced perception of fetal movements during the previous 10 hours. There was no history of abdominal trauma. Cardiotocograph showed nonreactive NST with minimal beat to beat variability for more than 40minutes. An emergency caesarean section was performed and a female limp baby delivered with heart rate <60/minutes, pale, no respiration and no reflexes. Baby resuscitated with bag and tube ventilated. APGAR score was 3/5/6 at 0, 1, and 5 minutes. Fetal haemoglobin at the first hour of life was 3.0gm/dl. Kleihauer-Betke test revealed 265.7ml of fetal erythrocytes in the maternal blood stream. Despite being rare, it is important to detect a massive feto-maternal haemorrhage. Fetal anemia could be suspected, but the diagnosis was only made after delivery. This case reveals the importance of keeping a high suspicion in obstetric practice, as feto-maternal haemorrhage is a rare but potentially catastrophic event for a fetus.

Correlation of admission labour admission test in low risk pregnancies with pregnancy outcome

Background: Aim of the study was to evaluate the role of NST (labour admission test) as a screening method in management of low risk pregnancies and to study the correlation of NST with fetal outcome.Methods: A prospective observational study conducted over 500 patients managed at our centre after proper evaluation. Patients were evaluated for mode of delivery and neonatal outcome.Results: The maximum number 352 of patients belonged to 20-30 years age group, 113 patients belonged to 31-35 age group. 200 patients were of 37-40 weeks gestation and 185 were of 40-41 weeks gestation. There were 125 patients in the 41-42 weeks gestational period. Among the 500 pregnant mothers who were included in the study 82.6% had Normal NST, 11.6% had suspicious and 5.8% had pathological NST. Cesarean rate was 14.4% in normal NST group, 58.62% in suspicious group and 72.41% in pathological group study. 6.77% in Normal group had meconium stained liquor at delivery whereas 29.31% in suspicious group and 37.93% in pathological group had same.Conclusions: The non-stress test is an important screening tool to identity the fetus in jeopardy in utero. This enables an appropriate timely intervention to achieve the most favorable outcome.

Objective:To investigate the efficacy and safety of different doses of tirofiban combined with coronary artery intervention in treatment of Non ST-segment elevation acute coronary syndromes (NST-ASC).Methods:110 cases with NST-ACS from October 2014 to January 2016 in our hospital were chosen and divided into the all dose group and half dose group.The TIMI blood grade before and after treatment,cardiac function before and after treatment for 30 d,major adverse cardiac events and bleeding events,hospitalization expenses and hospitalization days were recorded and compared between two groups.Results:Compared with before treatment,the TIMI 2 grade and 3 grade were obvious decreased,and the left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV) after treatment for 30 d were all obvious decreased,while the left ventricular ejection fraction (LVEF) were significant increased,P＜0.05.And the TIMI blood flow grading,LVEDV,LVESV and LVEF before and after treatment in two groups had no significant difference (P＞0.05),and the major adverse cardiac events and hospitalization days of two groups had no significant difference,P＞0.05.While the bleeding events and hospitalization expense of all dose group was obvious higher than those of half dose group,P＜0.05.Conclusions:The half dose group of tirofiban combined with coronary artery intervention in treatment NST-ACS has obvious efficacy,it can decrease the bleeding events and hospitalization expense.

La Enfermedad de Parkinson: Etiología, Tratamientos y Factores Preventivos / Parkinson Disease: Etiology, Treatments and Preventive Factors

La enfermedad de Parkinson (EP) es la patología neurodegenerativa motora con mayor incidencia a nivel mundial, cuyas causas aún no son claras. Actualmente no existe cura, pero es posible contar con diferentes tratamientos que permiten aliviar algunos de sus síntomas y enlentecer su curso. Debido a la gran cantidad de informaciones, en ocasiones contradictorias sobre los llamados "factores de riesgo" (entendidos éstos como situaciones que pueden exacerbar la posibilidad de aparición de la enfermedad, incluyendo desde la predisposición familiar hasta la exposición prolongada a substancias exógenas), en esta revisión se pretende ofrecer una panorámica actual sobre factores asociados a la aparición de EP Se revisan también algunos tratamientos que buscan contrarrestar la pérdida de la función dopaminérgica de la substancia nigra (SN) y algunas de las aproximaciones terapéuticas tanto farmacológicas, como por estimulación cerebral profunda (ECP) o por implante celular. Se revisan también investigaciones sobre el potencial terapéutico de compuestos con alta especificidad a receptores colinérgicos (nAChRs) y antagonistas de receptores de adenosina, específicamente del subtipo A2A. Posiblemente durante las próximas décadas, nuestro conocimiento en epigenética pueda arrojar nuevas luces sobre esta interacción, así como sobre las relaciones entre ciertas líneas de microbios intestinales y aparición de EP. En este momento, la alternativa terapéutica que ofrece mayor eficacia es la ECP, sin embargo, a futuro se espera que el desarrollo de nuevas estrategias de implante cerebral pueda ofrecer una cura real de la EP.

Parkinson's disease (PD) is the most prevalent neurodegenerative motor pathology worldwide, the causes of which are still unclear. Currently there is no cure, but it is possible to have different treatments that allow to alleviate some of its symptoms and slow its course. Due to the large amount of information, sometimes contradictory, about the so-called "risk factors" (understood as situations that may exacerbate the possibility of the onset of the disease, from family predisposition to prolonged exposure to exogenous substances), in this review aims to provide a current overview of factors associated with the occurrence of PD. We also review some treatments that seek to counteract the loss of the dopaminergic function of the substance nigra (SN) and some of the therapeutic approaches both pharmacologically, by deep brain stimulation (DBS) or by cellular implantation. Also reviewed investigations on the therapeutic potential of compounds with high specificity to cholinergic receptors (nAChRs) and adenosine receptor antagonists, specifically the A2A subtype. Possibly, during the next decades, our knowledge in epigenetics may shed new light on this interaction, as well as on the relationships between certain lines of intestinal microbes and onset of PD. At this time, the most effective therapeutic alternative is DBS; however, in the future it is expected that the development of new brain implant strategies may offer a real cure for PD.

Adaptive thermogenesis of the brown adipose tissue in tree shrews (Tupaia belangeri) during cold acclimation / 中国实验动物学报

Objective To investigate the effect of ambient temperature on body mass, thermogenic activity and un-coupling protein-1 ( UCP1) content of brown adipose tissue ( BAT) in tree shrews ( Tupaia belangeri) , and to provide the-oretical basis for establishing tree shrews model of obesity.Methods Forty healthy adult tree shrews with similar body mass were uesd in our experiment.The tree shrews were divided into five groups (n=8):control group (0 d), the ani-mals were maintained under 25 ±1℃ and 12L:12D ( light : dark, lights on 08:00) photoperiod; and the animals were maintained under 5 ±1℃and 12L:12D photoperiod for 7 d, 14 d, 21 d and 28 d groups, respectively.At the end of ex-periment, the changes of body mass, nonshivering thermogenesis (NST), BAT mass and uncoupling protein 1 (UCP1) con-tent were determined.Results Compared with the control group (0 d), the body mass, NST, BAT mass and UCP1 con-tent of the cold acclimation groups were improved significantly, the BAT color also obviously deepened, and after cold accli-mation for 28 d, the body mass, NST, BAT mass and UCP1 content were increased by 26.32%, 20.65, 53.85%and 43%, respectively.Apparently, the UCP1 content was significantly positively correlated with BAT mass and NST.Conclusions BAT proliferation may be induced and UCP1 expression upregulated by cold acclimation in Tupaia belangeri, therefore, en-hancing the thermogenic activity of brown adipose tissue to increase energy expenditure.We would speculate that BAT might be used as a target organ for treatment of obesity by energetic approach in the future.

Clinical Nutrition Service in Korean Tertiary Hospitals and General Hospitals: Result of Nationwide Cross-Sectional Survey

The purpose of this study was to investigate the status of clinical nutrition services provided at tertiary hospitals and general hospitals in Korea. In total, 157 questionnaires were distributed to the departments of nutrition at hospitals on September 2013. The results of this study are as follows. The median number of beds was 607 and average length of stay was 8 days. 63.1% of dietitians had over 5 years of career experience. Nutritional screening rate was 97% in tertiary hospitals but only 67.2% in general hospitals (P<0.001). The rate of equipment with computerized nutritional screening system was 100% in tertiary hospitals but 71.9% in general hospitals (P<0.001). Hospitals with the best regarding nutritional care were hospitals accredited by JCI (Joint Commission International). On the other hand, hospitals not accredited by the JCI but KOIHA (Korea Institute for Healthcare Accreditation) showed the lowest performance rate of nutritional care. Nutrition support teams (NSTs) were established in all tertiary hospitals but in only 73% of general hospitals (P<0.001). The rate of actively operating NSTs was 89% in tertiary hospitals but only 62% in general hospitals (P<0.001). There is a need to provide proper standardized clinical nutrition services as a primary treatment and we observed large variations in the quality of nutritional service between hospitals. Therefore, local solutions are needed to implement nutritional programs and policies for improved service and care.

Extent of ST-Segment Depression Predicts In- Hospital Outcome in Non ST-Segment Elevation Acute Coronary Syndrome.

Background: The presence of ischemic ECG changes on admission has been shown to predict outcome, the relationship between the extent of ECG changes and the risk of cardiac events is still ill defined. The severity of ST-segment depression on admission ECG has a strong association with adverse in-hospital outcome in patients with non ST-segment elevation acute coronary syndrome. The study was done to observe the extent of ST-segment depression and in-hospital outcome in patients with non ST-segment elevation acute coronary syndrome. Methods: This study was conducted in the Department of Cardiology in NICVD Dhaka, from January 2006 to December 2007. Considering inclusion and exclusion criteria, a total of 183 patients were evaluated. All the patients were evaluated clinically after admission. ECG, blood biochemistry and echocardiography were done. Patients were categorized into three groups according to the extent of ST- segment depression. Results: In this study, analysis of the baseline parameters revealed no statistically significant difference among the three groups of patients (p>0.05). Mean sum of the ST-segment depression analysis was done and all mean values were more in group III patients. 41.0% patients developed complications during the study period. Acute LVF (22.9%) was the most common complication followed by arrhythmia (11.5%), cardiogenic shock (4.4%) and STEMI (2.2%). All the complications were more in group III patients. During this period 6% patients died and more death (12.3%) was observed in group III patients. Conclusion: The amount of ST-segment depression is a powerful predictor of adverse in-hospital outcome in patients with non ST-segment elevation acute coronary syndrome.

Dysphagia Rehabilitation by the Nutritional Support Team (NST) / 日本農村医学会雑誌

With the advent of an aging society, the number of patients with dysphagia due to diseases such as eating disorders, dementia, and cerebrovascular disorders is increasing. To help such patients safely take oral drugs, pharmacists in nutrition support teams (NST) must have a good knowledge of swallowing.  A survey of swallowing conducted by a medical team of our hospital has rerealed causes of choking, nutritional status, intraoral conditions, etc in patients with difficulties in swallowing. Based on the survey findings, the team has come up with pamphlets on training in how to swallow easily and started to implement the training program.  When pharmacists are involved in the swallowing training, they need to recognize the problems associated with dysphagia in patients, and provide swallowing training according to the situation so that patients can take drugs orally. In addition, selection of oral drugs that can be taken easily, selection of drugs, such as adhesive skin patches and inhalants are important. It is also necessary to exrcise ingenuity in administring safe drugs oraly using thickening agents.  It is considered that maintenance of a good swallowing function in elderly persons is related to an improvement in their quality of life (QOL). To contribute to QOL improvement in patients and their families, knowledge and skills for solving swallowing problems are necessary for pharmacists.

Validating a Nutrition Support Team's (NST) Effect in Convalescent Stroke Rehabilitation using the Functional Independence Measure / The Japanese Journal of Rehabilitation Medicine

The aim of this study is to validate the effect of a nutrition support team's (NST) interventions in convalescent stroke rehabilitation using the Functional Independence Measure (FIM). Three hundred and four patients were retrospectively divided into an NST-nourishment group, an NST-losing-weight group and a non-NST group. We then compared the FIM gain, the FIM efficiency and the change of body mass index during admission among these three groups. The FIM gain was 17.3±15.9 in the NST-nourishment group and 16.7±12.5 in the non-NST group and there was no significant difference. The FIM efficiency in the NST-nourishment group (0.20±0.19) was significantly lower than the one in the non-NST group (0.27±0.19). Patients with an FIM of 53 or less showed no significant difference in FIM gain and FIM efficiency between the two groups. Since those patients who received NST intervention would tend to have a poor prognosis in general, we assumed that our “no difference” results indicated the effectiveness of the NST intervention. There was no evident relationship between FIM gains and changes in the body mass index.

Nonmyeloablative Stem Cell Transplantation in a Patient with Refractory Acute Myeolgeous Leukemia with Central Diabetes Insipidus / 대한혈액학회지

A 31-year-old man presented fatigue, polydipsia and polyuria. He was diagnosed as acute myelogenous leukemia (AML) FAB-M1, and a water deprivation test confirmed central diabetes insipidus (DI). A sella magnetic resonance imaging showed the thickening of pituitary stalk with contrast enhancement suggesting leukemic infiltration. He was treated with remission induction chemotherapy including cytosine arabinoside and idarubicin, and concurrent intrathecal methotrexate, cytosine arabinoside and hydrocortisone. But he was not achieved a remission. Reinduction chemotherapy was also failed to induce remission. He underwent a non-myeloablative allogeneic he matopoietic stem cell transplantation (NST) from HLA one antigen mismatched sibling donor for refractory AML. After transplantation, he had no evidence of leukemia and DI, He showed complete conversion of donor chimerism. By day 7 after NST, desmopressin (DDAVP) was no longer required and a follow-up at 9 months he has no evidence of relapse. We report a rare case recovered from diabetes insipidus associated with acute myelogenous leukemia after NST in Korea.

The efficacy of rapid biophysical profile for assessment of fetal well-being / 대한산부인과학회잡지

OBJECT: The nonstress test(NST) and complete biophysical profile(BPP) were compared with the rapid biophysical profile(BPP) in order to evaluate the efficacy of the rapid BPP, namely, the combination of amniotic fluid index(AFI) and sound-provoked fetal movement(SPFM) detected by ultrasound, in predicting intrapartum fetal distress in high-risk pregnancies. STUDY DESIGN: From JAN 9th 2000, through JAN 5th 2001, the prospective study of diagnostic tests was conducted on a total of 91 high-risk singleton pregnancies, undergoing antepartum assessment both the standard NST and the new rapid BPP(including other indices of complete BPP). The diagnostic indices of the NST, rapid BPP and complete BPP were calculated in term of predicting intrapartum fetal distress. RESULT: The sensitivity, specificity, negative predictive value, and positive predictive value of NST were 50.00, 94.81, 96.05, and 42.86% respectively, and those of rapid BPP were 75.00, 98.53, 98.53, and 75.00%, and those of complete BPP were 83.33, 98.72, 98.72, and 83.33%, as well. In addition, the efficiency of NST, rapid BPP, and complete BPP were 91.57%, 97.22% and 97.62% respectively. CONCLUSIONS: The rapid BPP is an effective and reliable predictor of intrapartum fetal distress with high-risk pregnancies. Moreover, it may be inexpensive and less time-consuming method.
