RESUMO

INTRODUCTION: The aim of this study was to analyse the clinical characteristics of patients with rheumatoid arthritis receiving biologics therapy and investigate the association between types of biologics and tuberculosis (TB) infections in 13 tertiary hospitals in Malaysia. MATERIALS AND METHODS: This was a retrospective study that included all RA patients receiving biologics therapy in 13 tertiary hospitals in Malaysia from January 2008 to December 2018. RESULTS: We had 735 RA patients who received biologics therapy. Twenty-one of the 735 patients were diagnosed with TB infection after treatment with biologics. The calculated prevalence of TB infection in RA patients treated with biologics was 2.9% (29 per 1000 patients). Four groups of biologics were used in our patient cohort: monoclonal TNF inhibitors, etanercept, tocilizumab, and rituximab, with monoclonal TNF inhibitors being the most commonly used biologic. The median duration of biologics therapy before the diagnosis of TB was 8 months. 75% of patients had at least one co-morbidity and all patients had at least one ongoing cDMARD therapy at the time of TB diagnosis. More than half of the patients were on steroid therapy with an average prednisolone dose of 5 mg daily. CONCLUSION: Although the study population and data were limited, this study illustrates the spectrum of TB infections in RA patients receiving biologics and potential risk factors associated with biologics therapy in Malaysia.

RESUMO

OBJECTIVE: To observe the efficacy of Danggui Buxue decoction (, DBD) on diabetic nephropathy-induced renal fibrosis in rats, and to study the possible mechanism. METHODS: Sixty male Goto Kakizaki (GK) rats were randomly assigned to the model group, gliquidone group, astragaloside IV group, and high-, medium- and low-doses DBD groups. After 8 weeks, changes in body weight, blood glucose, serum creatinine, serum urea nitrogen, and total cholesterol were observed. Changes in transforming growth factor-ß1 (TGF-ß1), Smad3, and Smad5 pathways and the expression of the fibrosis-related proteins collagen IV (col IV), α-smooth muscle actin (α-SMA), and vimentin were assessed. The degree of renal fibrosis was observed by immunohistochemistry and Mason staining. The expression of interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor (TNF-α), and C-reactive protein (CRP) in the kidneys was assessed using enzyme linked immunosorbent assay. RESULTS: Our experiments showed that DBD effectively reduced blood glucose, blood urea nitrogen, and creatinine levels after 8 weeks of administration, improved renal function in diabetic rats, alleviated renal fibrosis, and reduced the renal tissue levels of IL-6, IL-10, TNF-α, and CRP. Furthermore, DBD decreased the expression of TGF-ß1, Smad3, col IV, α-SMA, and vimentin in renal tissues and increased the expression of Smad5. CONCLUSIONS: DBD ameliorates diabetic renal interstitial fibrosis by modulating the TGF-ß1/Smads pathway.

RESUMO

BACKGROUND: Rifapentine is a rifamycin with unique bactericidal activity against Mycobacterium tuberculosis. It is also a potent inducer of CYP3A activity. However, the duration of rifapentine-induced hepatic enzyme activity after withdrawal is unclear. CASE REPORT: We report a case of a patient with Aspergillus meningitis treated with voriconazole after discontinuing rifapentine. Within ten days of rifapentine discontinuation, serum levels of voriconazole failed to reach the effective treatment range. CONCLUSIONS: Rifapentine is a potent inducer of hepatic microsomal enzymes. The induction of hepatic enzymes may exceed ten days after rifapentine discontinuation. Clinicians should be reminded of residual enzyme induction by rifapentine, especially when treating critically ill patients.

RESUMO

OBJECTIVE: To develop and test the health education knowledge assessment questionnaire for gout and to investigate the understanding degree of health education knowledge in patients with gout. METHODS: From June 2019 to June 2019, 150 cases of gout patients were enrolled.According to the literature review and the healthy education requirements of gout patients, the framework of education knowledge system was preliminarily formed.The pre-test questionnaire was obtained through two rounds of he Delphi technique.A survey of 150 patients with gout was carried out.The analysis and selection of the questionnaire were based on the coefficient of variation, the analysis of determination value, the correlation coefficient of the items and the total scores, and the exploratory factor analysis.In this study, we evaluated the reliability of internal consistency, semi-reliability.Validity test mainly included content validity and construct validity.In addition, a total of 150 patients with gout in our hospital and outpatient gout were selected to investigate the understanding degree of health education knowledge from June 2019 to December 2019. RESULTS: The significance of the first level index of the questionnaire was 3.83-5.00, the secondary index was 3.00-4.83, and the variation coefficient of each item was 0.31-1.23, and the critical ratio(CR) value of each item in this questionnaire was 3.168-8.333.The Pearson correlation coefficient of each item and the total score of this study was 0.319-0.544.After exploratory factor analysis, some topics were deleted in four dimensions, and there were 16 entries in the final questionnaire.Cronbach' s α coefficient of this questionnaire was 0.715, split-half reliability Spearman-Brown coefficient was 0.785, and retest reliability coefficient was 0.729. The correlation coefficient between each factor of this questionnaire and the total questionnaire was 0.300-0.701, and the correlation coefficient between each item of the questionnaire and each factor was 0.402-0.732, all P < 0.05. The results were statistically significant. By questionnaire investigation, the total score of questionnaire was (6.85±3.22), the score of disease-related knowledge was (2.03±1.24), the score of dietary guidance was (1.53± 1.06), the score of exercise guidance was (2.19±1.24), the score of medication guide was (1.24±1.22). CONCLUSION: The Health Education Knowledge Assessment Questionnaire For Gout has a good reliability and validity for measuring related content, the compilation process is scientific and the content is comprehensive, which can be further applied in clinic.The understanding degree of health education knowledge is low in Chinese patients with gout, and knowledge of gout medicine is lacking especially.

RESUMO

The association of breast implants and anaplastic large cell lymphoma (BIA-ALCL) was first described in 1997. Such an association has aroused public health concerns on breast implant safety. A systematic review was carried out with a pooled analysis of data. In total, 674 non-duplicate articles were retrieved; 77 articles were included for data extraction; 395 patients were identified for analysis. The median age at the time of diagnosis was 52 years. Implant texture was described in 201 (50.9%) patients; all 201 patients had a textured implant. The median time from the last implant insertion to diagnosis was 7.5 years. Most patients presented with seroma (67.1%, n = 265), 20.5% of patients presented with breast mass (n = 81). Patients with a breast mass at presentation, lymphadenopathy and those without seroma had more disseminated disease (P < 0.001). 73.2% of patients (n = 289) opted for primary surgery, among which 68.6% (n = 271) received removal of the implant, 61% (n = 241) received capsulectomy and 2% (n = 8) received mastectomy. Of note, 5.3% (n = 21) had reinsertion of an implant after primary surgery. Non-surgical modalities included chemotherapy, radiotherapy and haematopoietic stem cell transplant. The median follow-up interval was 2 years (range 0-14.5 years). Seventeen patients (4.3%) had recurrence of BIA-ALCL and 195 patients (49.4%) did not. The median duration to first recurrence was 1 year (range 1-3 years). Long-term clinical outcome was not reported in 183 patients. BIA-ALCL is an indolent disease that presents with seroma after implant insertion. A high index of suspicion is needed for early diagnosis and treatment.

RESUMO

The Fifth Neurocritical Care Research Network (NCRN) Conference held in Boca Raton, Florida, in September of 2018 was devoted to challenging the current status quo and examining the role of the Neurocritical Care Society (NCS) in driving the science and research of neurocritical care. The aim of this in-person meeting was to set the agenda for the NCS's Neurocritical Care Research Central, which is the overall research arm of the society. Prior to the meeting, all 103 participants received educational content (book and seminar) on the 'Blue Ocean Strategy®,' a concept from the business world which aims to identify undiscovered and uncontested market space, and to brainstorm innovative ideas and methods with which to address current challenges in neurocritical care research. Three five-member working groups met at least four times by teleconference prior to the in-person meeting to prepare answers to a set of questions using the Blue Ocean Strategy concept as a platform. At the Fifth NCRN Conference, these groups presented to a five-member jury and all attendees for open discussion. The jury then developed a set of recommendations for NCS to consider in order to move neurocritical care research forward. We have summarized the topics discussed at the conference and put forward recommendations for the future direction of the NCRN and neurocritical care research in general.

RESUMO

Treat-to-target (T2T) for gout has been established recently to improve its management, which has been reported to be sub-optimal with significant gaps between the goals of treatment and day-to-day clinical practice. T2T recommended a goal of serum urate (SUA) target of <360 µmoI/L in all patients with gout and <300 µmoI/L in patients with tophaceous or severe gout. T2T strategy was applied in the management of gout patients in two Rheumatology clinics from 1 January 2016 onwards. We performed a clinical audit to assess T2T of SUA in gout patients and to identify causes for failure to achieve target SUA among them. There were a total of 304 patients for our analysis. They were of multi-ethnic origin with male predominance (88.8%). They had a mean age of 57.7+13.7 years and mean disease duration of 10.1+8.7 years. The most common comorbidities were hypertension (76.2%), dyslipidemia (52.5%) and diabetes mellitus (DM) (27.4%). Our patients' body mass indexes showed that 47.7% were obese while 34.2% were overweight. Up to 62.4% of our patients had tophi and 42.6% had joint deformities. Only 34.9% of patients achieved target SUA. Nonadherence (52.3%) was the main reason identified for failure to achieve target SUA. The independent predictors for failure to achieve target SUA were nonadherence (HR=7.84, p=0.000) and presence of tophi (HR=1.95, p=0.001).

RESUMO

Infection is a major cause of morbidity and mortality among patients with systemic lupus erythematosus (SLE). To describe the pattern of serious infections in patients with SLE and to identify the predictors of infection-related mortality among SLE patients with serious infections, we prospectively studied all SLE patients who were hospitalized with infections in Sarawak General Hospital during 2011-2015. Demographic data, clinical features, and outcomes were collected. Cox regression analysis was carried out to determine the independent predictors of infection-related mortality. There were a total of 125 patients with 187 episodes of serious infections. Our patients were of multiethnic origins with female predominance (89.6%). Their mean age was 33.4 ± 14.2 years. The patients had a mean disease duration of 66.8 ± 74.0 months. The most common site of infection was pulmonary (37.9%), followed by septicemia (22.5%). Gram-negative organisms (38.2%) were the predominant isolates within the cohort. There were 21 deaths (11.2%) during the study period. Independent predictors of infection-related mortality among our cohort of SLE patients were flare of SLE (HR 3.98, CI 1.30-12.21) and the presence of bacteremia (HR 2.54, CI 0.98-6.59). Hydroxychloroquine was protective of mortality from serious infections (HR 9.26, CI 3.40-25.64). Pneumonia and Gram-negative organisms were the predominant pattern of infection in our SLE cohort. The presence of flare of SLE and bacteremia were independent prognostic predictors of infection-related mortality, whereas hydroxychloroquine was protective of infection-related mortality among SLE patients with serious infections.

RESUMO

We performed a retrospective study of all systemic lupus erythematosus (SLE) pregnancies during a 10-year period (2006-2015) to describe the clinical features, maternal and foetal outcomes in our centre. There were 115 pregnancies in 86 women with SLE. Our patients had a mean age of 29.1 years (SD 5.80) and a mean disease duration of 44.63 months (SD 41.17). Fifteen patients had antiphospholipid syndrome (APS). Our patients had complicated pregnancies: 26.1% had SLE flares, 13.9% had pre-eclampsia and 45.1% needed caesarean sections. There were 23.3% foetal losses and 25% preterm deliveries in our patients. There was a higher rate of unplanned pregnancies and lupus flare among pregnancies with active SLE at conception. Pregnancies in lupus nephritis have higher incidence of lupus flares during pregnancy but similar maternal and foetal outcomes compared to those without nephritis. The prognostic indicators for adverse foetal outcome in our patients were flare of SLE (HR 4.08 [CI 95% 1.65-10.13, p < 0.01]) and APS (HR 3.07 [CI 95% 1.12-8.42, p < 0.05]) and the prognostic indicator for adverse maternal outcome was hypertension (HR 3.58 [CI 95% 1.30-9.90, p < 0.05]). Lupus pregnancies in our centre remained as high-risk pregnancies with significant maternal and foetal complications.

RESUMO

The objective of this study was to compare the tolerability of methotrexate in two different regimes of folic acid (FA) supplementation in rheumatoid arthritis (RA). We performed a multicenter, cross-sectional observational cohort study on 240 RA patients with 120 patients each in 5 mg of FA weekly and 30 mg of FA weekly supplementation. There were no significant differences for side effects (14.2 versus 22.5%, P=0.523) and discontinuation of methotrexate (3.6 versus 13.3%, P=0.085). RA patients given 5 mg of FA weekly supplementation had a lower disease activity score 28 compared to 30 mg of FA weekly supplementation [3.44 (1.10) versus 3.85 (1.40), P=0.014]. FA supplementation of 5 mg per week and 30 mg per week was associated with similar tolerability of methotrexate in RA patients.

RESUMO

AIM: Factor XI (FXI) concentrate is a pooled human plasma-derived factor concentrate used as replacement therapy for patients with FXI deficiency, which provides a predictable response and consistent haemostatic cover in emergency or elective situations. It has previously been implicated in adverse events such as thrombosis and inhibitor formation, with rare case reports of fatal incidents. We sought to establish the incidence of such complications in a retrospective case series between 1994 and 2012 at the Haemophilia Comprehensive Care Centre at Royal Free Hospital, London, UK. METHODS: Patients who received FXI concentrate had their medical records reviewed to extract information and specific adverse events recorded such as failure of treatment with further bleeding, suspected viral transfusion transmitted infection (TTI), thrombosis or inhibitor formation. RESULTS: Eighty-six patients received 242 treatment episodes of FXI concentrate. Ninety percent of treatment episodes were covered with BPL FXI concentrate and 10% with LFB Hemoleven. Twelve (5%) adverse events were recorded, with eight (3.3%) of all treatment episodes were related to persistent bleeding postconcentrate infusion and there were 4 (1.7%) non-bleeding adverse events. No viral TTIs were identified. There were two recorded inhibitors, one thrombotic event (central retinal artery occlusion) and one transfusion reaction. No patient suffering an adverse event resulted in long-term morbidity. CONCLUSION: Our experience of FXI concentrate use demonstrates infrequent minor adverse events related to its administration and is a safe product to use.

RESUMO

Explosive blast shock waves and blunt impact to the head are two types of loading shown to result in mild traumatic brain injury (mTBI). While mTBI from these two causes shares some common features behaviorally, there are distinct differences in the pathophysiology of the underlying injury mechanisms. Various elucidations have been offered in the literature to explain the organic damage associated with mTBI resulting from both types of loading. The current state of understanding in this field is somewhat limited by the degree of appreciation of the physics and biomechanics governing the effects of explosive blast shock waves and blunt impact on the head, which has resulted in the various approaches to the investigation of the operative brain injury "wounding mechanisms". In this chapter we provide a simplified description of terminology associated with forces on the head from explosive blast shock waves and blunt impact, to assist readers in the field in evaluating interpretations of brain injury "wounding" processes. Remarkably, mTBI from either loading is shown generally to result in only a small loss of neurons, with hippocampal neurons appearing to be particularly vulnerable to explosive blast shock waves. Explosive blast studies in large animal models show a unique pattern of periventricular injury, which is different from the classic diffuse axonal injury. Both astrocyte and microglial activation are also seen in explosive blast as well as impact trauma, but this may be a general secondary brain injury response, nonspecific to explosive blast or blunt trauma. Additionally, while moderate to severe impact closed head injuries sometimes result in petechial hemorrhages or hematomas, they do not appear to be associated with explosive blast mTBI even with repeated exposure to blasts.

RESUMO

Accumulating clinical experience is indicating that explosive blast brain injury is becoming recognized as a disease distinct from the penetrating form of blast injury as well as the classic closed head injury (CHI). In recent US conflicts in Iraq and Afghanistan, over 60% of combat casualties were from explosive blast with the hallmark explosive weapon being the improvised explosive device (IED). Explosive blast TBI is a condition afflicting many combat injured warfighters potentially constituting another category of TBI. Clinically, it shares many features with conventional TBI but possesses some unique aspects. In its mild form, it also shares many clinical features with PTSD but here again has distinct aspects. Although military medical providers depend on civilian standard of care guidelines when managing explosive blast mTBI, they are continually adapting their medical practice in order to optimize the treatment of this disease, particularly in a theater of war. It is clear that further rigorous scientific study of explosive blast mTBI at both the basic science and clinical levels is needed. This research must include improved understanding of the causes and mechanisms of explosive blast TBI as well as comprehensive epidemiologic studies to determine the prevalence of this disease and its risk factors. A widely accepted unambiguous clinical description of explosive blast mTBI with diagnostic criteria would greatly improve diagnosis. It is hoped that through appropriate research meaningful prevention, mitigation, and treatment strategies for explosive blast mTBI can be speedily realized.

RESUMO

In the past, direct physical evidence of mild traumatic brain injury (mTBI) from explosive blast has been difficult to obtain through conventional imaging modalities such as T1- and T2-weighted magnetic resonance imaging (MRI) and computed tomography (CT). Here, we review current progress in detecting evidence of brain injury from explosive blast using advanced imaging, including diffusion tensor imaging (DTI), functional MRI (fMRI), and the metabolic imaging methods such as positron emission tomography (PET) and magnetic resonance spectroscopic imaging (MRSI), where each targets different aspects of the pathology involved in mTBI. DTI provides a highly sensitive measure to detect primary changes in the microstructure of white matter tracts. fMRI enables the measurement of changes in brain activity in response to different stimuli or tasks. Remarkably, all three of these paradigms have found significant success in conventional mTBI where conventional clinical imaging frequently fails to provide definitive differences. Additionally, although used less frequently for conventional mTBI, PET has the potential to characterize a variety of neurotransmitter systems using target agents and will undoubtedly play a larger role, once the basic mechanisms of injury are better understood and techniques to identify the injury are more common. Finally, our MRSI imaging studies, although acquired at much lower spatial resolution, have demonstrated selectivity to different metabolic and physiologic processes, uncovering some of the most profound differences on an individual by individual basis, suggesting the potential for utility in the management of individual patients.

RESUMO

Systemic lupus erythematosus (SLE) has been well studied in West Malaysian populations but lacking in East Malaysian populations. The aim of this study was to examine the clinical features and disease patterns of patients with SLE in a multiethnic East Malaysian population in Sarawak. All SLE patients who were treated in Sarawak General Hospital were reviewed in a retrospective longitudinal study using a standard protocol from 1 January 2006 to 31 December 2013. There were a total of 633 patients in our study with the female to male ratio of 12:1. Our study patients were of multiethnic origins with predominant Chinese ethnic group. They had a mean age of 36.9 ± 13.2 years and a mean duration of illness of 7.2 ± 6.0 years. The main involvements were haematological (74.2 %), malar rash (64.0 %) and renal (58.6 %). Chinese patients were less likely to have discoid lupus, pleuritis and pericarditis, while Malay patients were more likely to have arthritis. Bidayuh patients were more likely to have oral ulcer. Secondary antiphospholipid syndrome was more common in Chinese. The majority of patients were in clinical remission with low SDI. There were 58 deaths (9.2 %) during 2006-2013 with the main causes of death being flare of disease and infection.

RESUMO

we performed a prospective study of all hospitalized patients with a diagnosis of Gout in Sarawak General hospital from 1st July 2011 to 1st July 2012. There were a total of 126 patients in our study of which 112 (88.9%) were males. The majority of our patients were from the indigenous populations (71.7%). They have a mean age of 60.0 ± 14.2 years. Most of our patients were overweight (68%) with comorbities of hypertension (78.6%), Chronic Kidney Failure (48.4%), Type II diabetes Mellitus (30.2%), dyslipidemia (27.8%) and Ischaemic heart disease (11.9%). Polyarticular gouty arthritis was the main presenting pattern during hospitalization (88.1%). The mean length of stay for our patients was 9.8 ± 6.0 days which was significantly longer than the mean length of stay for other patients without gout (p<0.05). Only 17 patients had gout on admission and the majority developed gout during hospitalizations. Our patients were admitted respectively for medical problems (45.4%), surgical problems (28.6%) and orthopaedic problems (9.2%). Colchicine (73.8%) and steroid (40.5%) were the main stays of treatment for our patients. Our hospitalized gout patients were complicated patients with multiple comorbidities.

RESUMO

BACKGROUND: We investigated the biologic and pharmacologic activities of a chromosome region maintenance 1 (CRM1) inhibitor against human non-small cell lung cancer (NSCLC) cells both in vitro and in vivo. METHODS: The in vitro and in vivo effects of a novel CRM1 inhibitor (KPT-330) for a large number of anticancer parameters were evaluated using a large panel of 11 NSCLC cell lines containing different key driver mutations. Mice bearing human NSCLC xenografts were treated with KPT-330, and tumour growth was assessed. RESULTS: KPT-330 inhibited proliferation and induced cell cycle arrest and apoptosis-related proteins in 11 NSCLC cells lines. Moreover, the combination of KPT-330 with cisplatin synergistically enhanced the cell kill of the NSCLC cells in vitro. Human NSCLC tumours growing in immunodeficient mice were markedly inhibited by KPT-330. Also, KPT-330 was effective even against NSCLC cells with a transforming mutation of either exon 20 of EGFR, TP53, phosphatase and tensin homologue, RAS or PIK3CA, suggesting the drug might be effective against a variety of lung cancers irrespective of their driver mutation. CONCLUSIONS: Our results support clinical testing of KPT-330 as a novel therapeutic strategy for NSCLC.

RESUMO

INTRODUCTION: Ganglion cyst of the temporomandibular joint is a rare disease, which may arise from myxoid degeneration of the collagenous tissue of the temporomandibular joint capsule, without epithelial or endothelial lining. We report a case of cystic lesion in a 40-year-old female patient. OBSERVATION: The patient had a left pre-auricular oval-shaped swelling without any articular symptoms. The pathological analysis after surgical removal allowed diagnosing the lesion as a ganglion cyst of the left temporomandibular joint. DISCUSSION: We made a literature review and noted that this condition was predominant in female patients. We recommend using MRI for diagnostic purposes and surgery as the best therapeutic alternative.

RESUMO

OBJECTIVES: To describe the clinical oral health status, treatment needs and oral-health-related quality of life (OHRQoL) of older people admitted to older persons' wards at Dunedin Public Hospital due to a sudden worsening of their general health. Participants and methods: A systematic oral assessment was undertaken for a consecutive case series of 200 patients (59.5% female; mean age 82.6 years, sd 6.6) admitted to older person's wards at Dunedin Public Hospital. The Oral Health Impact Profile-20 (OHIP-20) was used to assess OHRQoL. RESULTS: One in three (36.0%) had been living independently at home prior to admission, and over half (55.0%) had been admitted for a medical reason which required assessment. Half (50.0%) of the participants were dentate (with an average of 16.8 teeth). There was an average of 1.9 decayed teeth present in the dentate group; 70.7% of individuals required restorations or extractions, and about 90% required only simple scaling of the teeth and prophylaxis. A reline or a replacement denture were required by three-quarters of those with dentures. Almost two-thirds of participants did not have a regular dentist, and fewer than one in three had made a dental visit in the previous year. One in six described their oral health as 'fair' or 'poor', and just under one-third reported dry mouth. Dentate participants, those without xerostomia, and those reporting better oral health had better OHRQoL, reflected in lower OHIP-20 scores. Affecting 37.1% of participants, functional limitation was the most commonly experienced of the OHIP-20 domains, followed by physical disability and physical pain (18.0% and 15.6% respectively). CONCLUSIONS: The oral health of medically compromised and functionally dependent but cognitively competent older people in this study is generally poor. If transfer to long-term care is indicated, early and proper preventive measures and appropriate dental contact should be advocated in order to reduce morbidity and improve quality of life for older people.
