Talcott Parsons on building personality system theory via psychoanalysis.

This article examines Talcott Parsons's efforts at building the theory of personality system as a special case of his general theory of action and places those efforts in historical context. I demonstrate how, during the middle decades of the twentieth century, Parsons employed elements of classic Freudian thought to advance a new appreciation of the personality system and its relations to other action systems. I begin with an overview of the reception of psychoanalysis at the Boston Psychoanalytic Society and Institute, the Massachusetts General Hospital, and the Harvard Department of Social Relations, showing how Parsons's thinking on the personality system cannot be understood apart from his association with these three institutions. I then turn to how Parsons endeavored to integrate his particular brand of sociology with his own interpretation of Freud's writings to explain how the personality system functions and develops. I conclude by showing that while Parsons's involvements with psychoanalysis became more intermittent after the mid-1950s, to the end of his life he remained steadfast in his enthusiasm for Freud's theory of personality. In short, Parsons always believed that for sociological theory to progress, it needed to engage with psychoanalysis.

[Evaluation of visceral adipose tissue and lipid level in premenopausal and postmenopausal women's]. / Evaluación del tejido adiposo visceral y de la concentración de lípidos en mujeres pre y posmenopáusicas.

BACKGROUND: Postmenopausal women present weight gain and intensification of obesity, especially visceral adipose tissue (VAT) increases in postmenopausal women. But it is still not clear whether abdominal fat increases during this stage independently of body weight. OBJECTIVE: compare the VAT and lipid profile between postmenopausal and premenopausal Mexican women. METHODS: A case control study in postmenopausal women matched for BMI with premenopausal women. Anthropometric and laboratory measurements as well as body composition analysis were performed. RESULTS: VAT was increased in postmenopausal women in contrast with premenopausal women (114.8 ± 39.5 vs 97.3 ± 29.0, p<0.05). Compared with premenopausal women, postmenopausal women showed higher total cholesterol (231 .6 ± 56.1 vs 206.8 ± 29.5 p <0.05), and LDL-cholesterol levels (145.9 ± 48.3 vs 121.7 ± 34.1, p < 0.05), whereas H DL-cholesterol remained unchanged. CONCLUSION: The results of the present study have demonstrated that Mexican postmenopausal women had a significant increment in visceral adipose tissue and in other metabolic risk factors, independent of the body mass index.

[Femoral hypoplasia-unusual facies syndrome: A case report]. / Síndrome de hipoplasia femoral y facies inusual: reporte de un caso.

INTRODUCTION: Femoral hypoplasia-unusual facies syndrome is a rare disease with variable expressivity, although cases have been reported with an autosomal dominant pattern. It particularly affects the structures of the face associated with hypoplasia of the femur. Its aetiology is relatively unknown. However, this syndrome has been associated with maternal diabetes, drug exposure, viral infections, radiation, and oligohydramnios. OBJECTIVE: The case of a newborn with this syndrome is presented. CLINICAL CASE: Newborn of 41 weeks gestation with small nose, thin upper lip, micrognathia, long philtrum, low set ears, epicanthal folds, dysplastic hips showing flexion, and adduction of the right leg, and shortening at the expense of the thigh. X-ray images revealed femoral hypoplasia and dysplastic acetabular roof. Different physicians from other specialties who excluded other associated malformations performed a complete evaluation. Surgical bone lengthening of lower limb is scheduled at 5 months of age, with the purpose that she walks with her own feet; at the same time she began management with kinesiotherapy. CONCLUSIONS: Femoral hypoplasia-unusual facies syndrome is a rare condition. A multidisciplinary health care team must treat individuals with femoral hypoplasia-unusual facies syndrome.

Predictors of in-hospital mortality in HIV-infected patients with COVID-19.

BACKGROUND: Underlying immunodeficiency is associated with severe COVID-19, but the prognosis of persons with human immunodeficiency virus (HIV) (PWH) with COVID-19 is under debate. Aim: assessment of the mortality rate and major determinants of death in HIV-infected patients hospitalized with COVID-19 in Spain before vaccine availability. Design: Retrospective nationwide public database analysis. METHODS: Nationwide, retrospective, observational analysis of all hospitalizations with COVID-19 during year 2020 in Spain. Stratification was made according to HIV status. The National Registry of Hospital Discharges was used with the ICD-10 coding list. RESULTS: A total of 117 694 adults were hospitalized with COVID-19 during 2020. Only 234 (0.2%) were HIV-positives. More than 95% were on antiretroviral therapy. Compared to HIV-negatives, PWH were younger (mean age 53.2 vs. 66.5 years old; P<0.001) and more frequently male (74.8% vs. 56.6%; P<0.001). Most co-morbidities predisposing to severe COVID-19 (diabetes, hypertension, dementia and cardiovascular disease) were more frequent in HIV-negatives. In contrast, the rate of baseline liver disease was over 6-fold higher in PWH (27.4% vs. 4.4%; P<0.001). In-hospital mortality was lower in PWH (9.4% vs. 16%; P=0.004). In multivariate analysis, older age, dementia and especially advanced liver disease (relative risk (RR): 7.6) were the major determinants of death in PWH hospitalized with COVID-19. CONCLUSION: HIV-infected patients hospitalized in Spain with COVID-19 during 2020 had better survival than HIV-negatives, most likely explained by younger age and lower rate of co-morbidities. However, advanced liver disease was a major predictor of death in PWH hospitalized with COVID-19.

[Clinical and radiographic factors associated with the severity of paraspinal fatty infiltration in patients with degenerative low back disease]. / Factores clínicos y radiográficos asociados a la severidad de infiltración grasa paraespinal en pacientes con enfermedad lumbar degenerativa.

INTRODUCTION: Degenerative lumbar disease (DLE) is a spectrum of pathological changes from disc degeneration, herniated disc, spondylolisthesis and lumbar canal stenosis. The pain associated with it is multifactorial. Muscle cramps are among the most frequent causes. The relationship between muscle degeneration and DLE has already been studied in the past in multiple studies, highlighting the one carried out by Kjaer & cols. OBJECTIVE: to determine the prevalence and severity of fatty degeneration in mutifidus spinae, and to study its relationship with clinical and radiographic factors. MATERIAL AND METHODS: observational and analytical study. Patients diagnosed with: herniated disc, lumbar canal stenosis or degenerative scoliosis were included. They were classified according to the Kjaer scale for paraspinal fatty infiltration in one of three groups. Clinical variables were analyzed: age, smoking, obesity, the presence of axial pain, temporality of pain, severity expressed with a visual analog scale (VAS); and radiographic: number of diseased segments, involved segments, diagnostic imaging and the presence of spondylolisthesis. RESULTS: 56 patients with an average age of 52.5 years (16 to 80) with a predominance of females with 62.5% were included. The diagnoses were nonspecific low back pain (1.8%), herniated disc (42.9%), narrow lumbar duct (46.4%) and lumbar duct with degenerative scoliosis deformity (8.9%). The distribution among the three groups described by Kjaer was as follows: 44.6% were classified with a fat infiltration score of 2. In groups 1 and 0, 39.3% and 16.1% were classified respectively. The variables significantly related to greater fat infiltration were: age > 60 years, diagnoses of lumbar canal stenosis and herniated disc; obesity, spondylolisthesis < 2 vertebral segments involved. Axial pain and VAS > 8 points were not related to greater muscle degeneration. CONCLUSIONS: fatty infiltration is present in all patients with some of the forms of DLE. Most patients > 60 years of age with advanced degenerative processes have a greater severity of infiltration. Other related variables are: obesity, spondylolisthesis and disease of < 2 vertebral segments. There is no relationship between a higher percentage of fatty infiltration and axial pain or higher VAS scores.

INTRODUCCIÓN: la enfermedad lumbar degenerativa (ELD) es un espectro de cambios patológicos desde la degeneración discal, la hernia discal, la espondilolistesis y el conducto lumbar estrecho. El dolor que se le asocia es multifactorial. Los espasmos musculares son de las causas más frecuentes. La relación que guarda la degeneración muscular y la ELD ya ha sido estudiada en múltiples trabajos, destacando el realizado por Kjaer y colaboradores. OBJETIVO: determinar la prevalencia y severidad de la degeneración grasa en el mutifidus spinae, y estudiar su relación con variables clínicas y radiográficas. MATERIAL Y MÉTODOS: estudio observacional y analítico. Se incluyeron pacientes diagnosticados con: hernia discal, conducto lumbar estrecho o escoliosis degenerativa. Se clasificaron de acuerdo con escala de Kjaer para infiltración grasa paraespinal en alguno de tres grupos. Se analizaron variables clínicas: edad, tabaquismo, obesidad, presencia de dolor tipo axial, temporalidad del dolor, severidad del dolor expresada con escala visual análoga (EVA); y radiográficas: número de segmento enfermos, segmentos involucrados, diagnóstico por imagen y presencia de espondilolistesis. RESULTADOS: se incluyeron 56 pacientes con edad promedio de 52.5 años (rango 16 a 80) con predominio del sexo femenino (62.5%). Los diagnósticos fueron lumbalgia inespecífica (1.8%), hernia discal (42.9%), conducto lumbar estrecho (46.4%) y conducto lumbar con deformidad en escoliosis degenerativa (8.9%). La distribución entre los tres grupos descritos por Kjaer fue la siguiente: 44.6% fueron clasificados con un puntaje de infiltración grasa de 2. En los grupos 1 y 0, se clasificaron 39.3 y 16.1%, respectivamente. Las variables relacionadas con mayor infiltración grasa fueron: edad > 60 años, diagnósticos de conducto lumbar estrecho y hernia discal; obesidad, espondilolistesis < 2 segmentos vertebrales involucrados. El dolor mecánico y EVA > 8 puntos no se relacionaron con mayor degeneración muscular. CONCLUSIONES: la infiltración grasa está presente en todos los pacientes con alguna de las formas de ELD. La mayoría de los pacientes > 60 años con procesos degenerativos avanzados tienen mayor severidad de infiltración. Otras variables relacionadas son: obesidad, espondilolistesis y enfermedad < 2 segmentos vertebrales. No hay relación entre mayor porcentaje de infiltración grasa y dolor axial o puntajes más altos de dolor.

Noncommunicable diseases risk factors and the risk of COVID-19 among university employees in Indonesia.

INTRODUCTION: Noncommunicable diseases (NCDs) are still a major public health problem in Indonesia. Studies have shown that risk factors of NCDs are associated with coronavirus disease 2019 (COVID-19) severity and mortality. However, it is unclear whether NCD risk factors are also risks for new COVID-19 cases. This study aimed to obtain an NCD risk profile among university employees and its associations with contracting COVID-19. METHODS: A cross-sectional study was conducted in October 2021. Participants were administrative employees of Universitas Indonesia (UI), Depok City, West Java. Assessment of NCD risk factors was based on the World Health Organization STEPwise approach to NCD risk factor surveillance (WHO STEPS). Demographic, working, and medical-history data were obtained electronically by using a Google Form. Physical and laboratory examinations were done in the Integrated Post for NCDs. Risks were expressed as adjusted odds ratio (ORadj) and 95% confidence interval (CI) in multivariate analyses. RESULTS: A total of 613 employees were enrolled. Men were predominant (54.8%), and about 36% of them work in shift as security personnel. About 66.7% were overweight or obese and 77.8% had hypertension. There were 138 (22.8%) employees who had COVID-19. Nearly all (95.6%) had been fully vaccinated against COVID-19. At-risk waist circumference (ORadj 1.72, 95% CI 1.15-2.56, p = 0.008) and total cholesterol level of 200-239 mg/dL (ORadj 2.30, 95% CI 1.19-4.44, p = 0.013) were independent risk factors, but shift work (ORadj 0.52, 95% CI 0.34-0.80, p = 0.003) was protective against COVID-19. CONCLUSION: The prevalence of NCD risk factors among university administrative employees was high, increasing the risk of contracting COVID-19. A behavioral intervention program to manage NCD risk factors at the university level is urgently needed according to the Health Promoting University framework.

Pancreatic cystic lesions. Differential diagnosis and treatment strategy.

The differential diagnosis of pancreatic cystic lesions (PCLs) includes non-neoplastic lesions and neoplastic epithelial lesions. Given that management is determined by the risk for malignant progression, associated symptoms, and other characteristics, an accurate diagnosis is imperative. The present review attempts to provide a critical path that facilitates the characterization and management of PCLs.

Use of anterolateral thigh free flap for reconstruction and salvage of thoracic limb caused by an arteriovenous malformation.

Vascular arteriovenous malformations originate during the early stages of embryonic development and generally grow progressively, especially during adolescence and pregnancy. Limb salvage using microsurgery is presented, in a patient with an arteriovenous malformation who was initially a candidate for limb amputation. En bloc resection of the arteriovenous malformation of all segments with extended brachial approach and the cutaneous component was performed, with an anterolateral thigh free flap for the lateral reconstruction of the hand.

Zinc and vitamin A supplementation fails to reduce sputum conversion time in severely malnourished pulmonary tuberculosis patients in Indonesia.

BACKGROUND: A previous study showed that combination of zinc and vitamin A reduced sputum conversion time in pulmonary tuberculosis (TB) patients. OBJECTIVE: We studied the efficacy of which single micronutrient contributed more to the sputum conversion time. METHODS: In a double-blind randomized community trial, newly sputum smear positive pulmonary TB patients were assigned randomly to receive zinc, vitamin A, zinc + vitamin A or placebo on top of TB treatment. Patients were asked to deliver their sputum on weekly basis to measure positivity of the bacteria. Nutritional status, chest x-ray, hemoglobin, C-reactive protein (CRP), retinol and zinc level were examined prior to, after 2 and 6 months of treatment. RESULTS: Initially, 300 patients were enrolled, and 255 finished the treatment. Most patients were severely malnourished (mean BMI 16.5 ± 2.2 Kg/m2). Patients in the zinc + vitamin A group showed earlier sputum conversion time (mean 1.9 weeks) compared with that in the other groups; however the difference was not significant. Also, no benefit could be demonstrated of any of the used supplementations on clinical, nutritional, chest x-ray, or laboratory findings. CONCLUSIONS: This study among severely malnourished TB patients, did not confirm that single or combined supplementation of zinc and vitamin A significantly reduced sputum conversion time or had other significant benefit.

Characterization of a novel automated microfiltration device for the efficient isolation and analysis of circulating tumor cells from clinical blood samples.

The detection and analysis of circulating tumor cells (CTCs) may enable a broad range of cancer-related applications, including the identification of acquired drug resistance during treatments. However, the non-scalable fabrication, prolonged sample processing times, and the lack of automation, associated with most of the technologies developed to isolate these rare cells, have impeded their transition into the clinical practice. This work describes a novel membrane-based microfiltration device comprised of a fully automated sample processing unit and a machine-vision-enabled imaging system that allows the efficient isolation and rapid analysis of CTCs from blood. The device performance was characterized using four prostate cancer cell lines, including PC-3, VCaP, DU-145, and LNCaP, obtaining high assay reproducibility and capture efficiencies greater than 93% after processing 7.5 mL blood samples spiked with 100 cancer cells. Cancer cells remained viable after filtration due to the minimal shear stress exerted over cells during the procedure, while the identification of cancer cells by immunostaining was not affected by the number of non-specific events captured on the membrane. We were also able to identify the androgen receptor (AR) point mutation T878A from 7.5 mL blood samples spiked with 50 LNCaP cells using RT-PCR and Sanger sequencing. Finally, CTCs were detected in 8 out of 8 samples from patients diagnosed with metastatic prostate cancer (mean ± SEM = 21 ± 2.957 CTCs/mL, median = 21 CTCs/mL), demonstrating the potential clinical utility of this device.

Malnutrition and socio-demographic factors associated with pulmonary tuberculosis in Timor and Rote Islands, Indonesia.

OBJECTIVE: To identify nutritional and socio-demographic factors for the development of tuberculosis (TB) in Timor and Rote Island, Indonesia, so that intervention programmes can be developed to address these factors. METHODS: In a case-control study, we enrolled new sputum smear-positive pulmonary TB patients as cases, and neighbours matched for sex and age as controls. Data obtained included history of TB, socio-demographic factors and nutritional status. RESULTS: In the study, 121 TB patients and 371 controls participated. The mean age was 30 years: 56.3% were male and 43.7% female. Of the TB patients, 87% had malnutrition compared to 33% among controls. The mean body mass index (BMI) of the patients was significantly lower than that of the controls (16.1 +/- 2.3 kg/m(2) vs. 19.4 +/- 3.0 kg/m(2)). Factors associated with the development of TB were BMI (OR 0.5, 95%CI 0.4-0.6), family history of TB (OR 3.2, 95%CI 1.6-6.4), living in an extended family (OR 2.7, 95%CI 1.5-4.8), being non-indigenous to Timor and Rote Islands (OR 2.9, 95%CI 1.2-6.8) and being unemployed (OR 3.8, 95%CI 1.7-8.6). CONCLUSION: Among patients with active pulmonary TB, the prevalence of malnutrition was very high. Malnutrition, which is a general problem for the whole community and particularly among people not indigenous to Timor and Rote, should be addressed in the fight against TB.

Capillaroscopy: A Valuable Diagnostic Tool. / Capilaroscopia: una herramienta diagnóstica valiosa.

Capillaroscopy produces in vivo images of skin microcirculation. It is a simple, noninvasive tool for analyzing microvascular abnormalities and, as such, can be used in both adults and children. Capillaroscopy has proven useful in many diseases, but it is of particular value in Raynaud phenomenon and other autoimmune diseases. The test is used to analyze capillaroscopic patterns in the nailfold bed of the second to fifth fingers of each hand. A normal capillaroscopic pattern is characterized by the presence of 7 to 11 capillaries in a hairpin shape. Pathologic patterns are characterized by morphologic and structural alterations, such as ectasias, giant capillaries, pathologic hemorrhages, avascular areas, and neoangiogenesis. In this article, we review the fundamentals of capillaroscopy, with an emphasis on the technique and its indications, diagnostic value, and use as a prognostic tool for rheumatologic disorders.

Synthesis of organic-inorganic hybrids via a high-pressure-ramp process: the effect of inorganic nanoparticle loading on structural and photochromic properties.

Organic polymerization remains a limiting step in the preparation of organic-inorganic hybrid materials with a strong concentration of the inorganic component. In this work, a high-pressure-ramp process was applied to achieve pHEMA-TiO2 nanoparticulate solids with an unprecedentedly high concentration (12 mol l-1) of the inorganic component, which is four times higher than that obtained after radical polymerization induced thermally or by photons. The inorganic nanoparticles underwent morphological and structural changes with an increase of Ti concentration above 1.5 mol l-1: they slightly coarsen and crystallize into an anatase polymorph. The material possesses a strong photochromic response related to the electron-hole separation at the organic-inorganic interface and can store 1e- per 5 Ti atoms. The electron storage capacity of the titania nanoparticles decreases upon crystallization.

Low vitamin D-25(OH) level in Indonesian multiple sclerosis and neuromyelitis optic patients.

BACKGROUND: Vitamin D deficiency is commonly found in multiple sclerosis (MS) and Neuromyelitis Optic (NMO) patients and can impair the immunological status. As a tropical country, Indonesia has a lot of sunshine throughout the year as a source of vitamin D. The aim of this study was to evaluate and compare the serum vitamin D-25(OH) level in Indonesian MS and NMO patients to healthy individuals. METHODS: A cross-sectional study was conducted in Dr. Cipto Mangunkusumo General Hospital Jakarta from November 2016 to May 2017. Forty-eight patients (29 MS and 19 NMO) and 33 healthy controls were enrolled. We assessed the dietary recall, vitamin D supplementation, sunshine exposure, medication, annual relapse rate, and Expanded Disability Status Scale (EDSS). Vitamin D level was measured using direct competitive chemiluminescence immunoassay. RESULTS: Vitamin D deficiency was found in 48.4% of MS and 56.2% of NMO patients. The serum vitamin D level in MS and NMO groups was not significantly different from the healthy controls. Vitamin D level was not associated with EDSS and the annual relapse rate. Positive significant correlation was observed between sunshine exposure and vitamin D level in healthy control, but not evident in MS and NMO groups. MS and NMO subjects who still treated with corticosteroid had lower vitamin D level. CONCLUSION: Vitamin D deficiency is commonly found in Indonesian MS and NMO patients, but not associated with EDSS and annual relapse rate. Despite living in a country with adequate sunshine exposure, the physician should anticipate low serum vitamin D level, especially in MS or NMO patients who received corticosteroid.

Drug-Induced Lung Injury in a Liver Transplant Patient Treated With Sofosbuvir.

New direct-acting antivirals (DAAs) have dramatically improved sustained virologic response (SVR) rates in patients treated for chronic hepatitis C. Although the safety of these agents has been very good in registration trials, unexpected side effects have been reported after much broader use of DAAs on marketing. We retrospectively examined all liver transplant recipients with chronic hepatitis C that received sofosbuvir-based regimens at our clinic. A total of 24 liver transplant recipients with recurrent chronic hepatitis C had received sofosbuvir up to April 2015. Regimens were as follows: sofosbuvir+simeprevir (8), SOF+ledipasvir (6), sofosbuvir+daclatasvir (5) and sofosbuvir+ribavirin (5). Overall, treatment was very well tolerated with only mild adverse events in 42% of patients. However, a 52-year-old woman developed severe respiratory failure within 10 days after beginning sofosbuvir+daclatasvir. High-resolution computerized tomography showed areas of diffused ground-glass opacities in both lungs, suggesting drug-induced lung injury. The bronchoalveolar lavage showed marked signs of acute inflammation without recovering any infectious agent. The patient was treated with high-dose corticosteroids and steadily recovered. DAA therapy was not discontinued, but sofosbuvir was replaced by simeprevir. She reached sustained virologic response after completing 24 weeks of DAA therapy. Given the close temporal association, radiologic and bronchoalveolar lavage findings, and negative work-up for infectious agents, we postulated that sofosbuvir was the most likely explanation for drug-induced lung injury in our patient.

Normal renin uremic hypertension. Study of cardiac hemodynamics, plasma volume, extracellular fluid volume, and the renin angiotensin system.

Studies were undertaken in 33 uremic patients with or without hypertension, 11 normal subjects, and 15 essential hypertensive patients to assess cardiac hemodynamics, plasma volume, extracellular fluid volume, and peripheral renin levels. Cardiac output and intraarterial blood pressure were measured and peripheral vascular resistance index calculated. These studies suggest that uremic hypertension with normal renin values and hypervolemia is hemodynamically sustained by an increase in peripheral resistance rather than by an increased cardiac output. The renin angiotensin system plays a secondary role as compared to overexpansion in the genesis of hypertension in normoreninemic uremic hypertension.

Knowledge and perception of tuberculosis and the risk to become treatment default among newly diagnosed pulmonary tuberculosis patients treated in primary health care, East Nusa Tenggara: a retrospective study.

BACKGROUND: Despite the high efficacy of tuberculosis (TB) drug regiments, one of the barriers in the TB control program is the non-compliance to treatment. Morbidity, mortality, and risk to become resistant to drugs are emerging among defaulters. Thus, the aim of this study is to identify the factors, especially knowledge and perceptions of TB and association with treatment default among patients treated in primary care settings, East Nusa Tenggara. METHODS: This study was part of a bigger cohort community-based controlled trial study. The subjects were newly diagnosed pulmonary TB patients from four districts in East Nusa Tenggara. Knowledge, perception of TB, and other related factors were assessed prior to the treatment. Patients who interrupted the treatment in two consecutive months were classified as defaulters, as World Health Organization stated. Odds ratio (OR) looking for factors associated with becoming defaulter was analyzed. RESULTS: A total of 300 patients were recruited for this study. At the end of the treatment, 255 patients (85%) completed the treatment without interruption from regular visit. In univariate analysis, none of the socio-demographic factors attributed to treatment default yet lack of knowledge and incorrect perception of TB prior therapy (OR 2.49 1.30-4.79 95% CI, p = 0.006; OR 5.40 2.64-11.04 95% CI, p < 0.001, respectively). In multivariate analysis, only incorrect perception of TB showed significant association with treatment default (OR 4.75 2.30-9.86 95% CI). CONCLUSIONS: Assessing the knowledge and perception of TB prior to the treatment in newly pulmonary TB patients is important as both of them were known as risk factor for treatment default. Education and counseling may be required to improve patients' compliance to treatment.

Effectiveness of the Bacillus Calmette-Guerin vaccine in an Indonesian population with D543N NRAMP1 polymorphism.

INTRODUCTION: Bacille Calmette-Guerin (BCG) vaccination remains a routine immunization in primary care in tuberculosis (TB)-endemic areas, though several studies found that its efficacy was inconclusive. Natural resistance-asociated machrophage protein 1 (NRAMP1) polymorphism has been shown to result in higher susceptibility to TB. Information on genetic susceptibility in populations will be useful in planning the application of the BCG vaccine. The present study explored BCG efficacy in a rural Timor population with specific NRAMP1 polymorphism in a TB-endemic region of eastern Indonesia. METHODOLOGY: A case-control study with 64 newly diagnosed pulmonary TB patients and 65 healthy controls was performed. BCG scars were examined by a physician. NRAMP1 polymorphism was evaluated using molecular methods. RESULTS: Half of the subjects (65; 50.4%) had a clear presenting BCG scar on the upper arm, suggesting a successful BCG vaccination. Among the subjects, D543N NRAMP1 polymorphism, history of contact with TB patients, and not having a clear BCG scar on the upper arm tended to be significantly association with active TB. The significant differences were more profound when subjects were divided based on presenting BCG scar. Subjects without clear BCG scars had significant association with developing TB disease (p = 0.014). In multivariate analysis, history of previous contact with TB patients and unclear presenting BCG scar were associated with active TB (OR 9.2; 2.0-43.8 95% CI, OR 4.8; 2.1-11.0 95% CI, respectively). CONCLUSIONS: BCG vaccination in our population was effective for TB protection, especially in highly endemic areas of TB, regardless genetic susceptibility.

Central nervous system DNA fragmentation induced by the inhibition of nuclear factor kappa B.

Ageing of the central nervous system (CNS) is characterized by a progressive apoptotic loss of neurons that may be in part due to impaired neurotrophin signaling mediated by such elements as the transcription factor nuclear factor kappa B (NFkappaB). To support this hypothesis, we inhibited nuclear translocation of NFkappaB in vivo by injecting a proteasome inhibitor (PSI) directly in the CNS lateral ventricle of rats and then measured fragmented DNA in various CNS areas as an index of ongoing apoptosis. Our results show that after PSI injection there was a significant inhibition of NFkappaB activity in vivo that resulted in the appearance of fragmented (apoptotic) DNA in the CNS of rats. These results suggest that alteration of NFkappaB may cause apoptotic cell death in the rat CNS during ageing.

Left atrial reduction and mitral valve surgery: the "functional-anatomic unit" concept.

The desired outcome for patients undergoing mitral valve surgery includes both good function of the mitral valve, and preservation and restoration of sinus rhythm. To achieve such an outcome, we evolved the concept of the left atrium and mitral valve as a "functional anatomic unit." In this report, we describe a technique for reduction in left atrial size, isolation of the pulmonary veins, and amputation of the left atrial appendage in combination with mitral valve repair. We performed such a procedure in 4 patients, with rheumatic mitral valve disease and chronic atrial fibrillation, with restoration of good valve function and sinus rhythm at 16 to 20 months after surgery.
