RESUMO

Importance: Clinical experience suggests that hospital inpatients have become more complex over time, but few studies have evaluated this impression. Objective: To assess whether there has been an increase in measures of hospital inpatient complexity over a 15-year period. Design, Setting and Participants: This cohort study used population-based administrative health data from nonelective hospitalizations from April 1, 2002, to January 31, 2017, to describe trends in the complexity of inpatients in British Columbia, Canada. Hospitalizations were included for individuals 18 years and older and for which the most responsible diagnosis did not correspond to pregnancy, childbirth, the puerperal period, or the perinatal period. Data analysis was performed from July to November 2023. Exposure: The passage of time (15-year study interval). Main Outcomes and Measures: Measures of complexity included patient characteristics at the time of admission (eg, advanced age, multimorbidity, polypharmacy, recent hospitalization), features of the index hospitalization (eg, admission via the emergency department, multiple acute medical problems, use of intensive care, prolonged length of stay, in-hospital adverse events, in-hospital death), and 30-day outcomes after hospital discharge (eg, unplanned readmission, all-cause mortality). Logistic regression was used to estimate the relative change in each measure of complexity over the entire 15-year study interval. Results: The final study cohort included 3 367 463 nonelective acute care hospital admissions occurring among 1 272 444 unique individuals (median [IQR] age, 66 [48-79] years; 49.1% female and 50.8% male individuals). Relative to the beginning of the study interval, inpatients at the end of the study interval were more likely to have been admitted via the emergency department (odds ratio [OR], 2.74; 95% CI, 2.71-2.77), to have multimorbidity (OR, 1.50; 95% CI, 1.47-1.53) and polypharmacy (OR, 1.82; 95% CI, 1.78-1.85) at presentation, to receive treatment for 5 or more acute medical issues (OR, 2.06; 95% CI, 2.02-2.09), and to experience an in-hospital adverse event (OR, 1.20; 95% CI, 1.19-1.22). The likelihood of an intensive care unit stay and of in-hospital death declined over the study interval (OR, 0.96; 95% CI, 0.95-0.97, and OR, 0.81; 95% CI, 0.80-0.83, respectively), but the risks of unplanned readmission and death in the 30 days after discharge increased (OR, 1.14; 95% CI, 1.12-1.16, and OR, 1.28; 95% CI, 1.25-1.31, respectively). Conclusions and Relevance: By most measures, hospital inpatients have become more complex over time. Health system planning should account for these trends.

RESUMO

OBJECTIVE: New prognostic biomarkers, and bio-signatures, are urgently needed to facilitate a precision medicine-based approach to more effectively treat patients with high-grade serous ovarian cancer (HGSC). In this study, we analysed the expression patterns of a series of candidate protein biomarkers. METHODS: The panel of markers which included MyD88, TLR4, MAD2, PR, OR, WT1, p53, p16, CD10 and Ki67 was assessed using immunohistochemistry in a tissue microarray (TMA) cohort of n = 80 patients, composed of stage 3-4 HGSCs. Each marker was analysed for their potential to predict both overall survival (OS) and progression-free survival (PFS). RESULTS: TLR4 and p53 were found to be individually predictive of poorer PFS (Log Rank, p = 0.017, p = 0.030 respectively). Cox regression analysis also identified high p53 and TLR4 expression as prognostic factors for reduced PFS (p53; HR=1.785, CI=1.036-3.074, p = 0.037 and TLR4; HR=2.175, CI=1.112-4.253, p = 0.023). Multivariate forward conditional Cox regression analysis, examining all markers, identified a combined signature composed of p53 and TLR4 as prognostic for reduced PFS (p = 0.023). CONCLUSION: Combined p53 and TLR4 marker assessment may help to aid treatment stratification for patients diagnosed with advanced-stage HGSC.

RESUMO

Human papillomavirus (HPV) infection has been identified as a significant etiological agent in the development of head and neck squamous cell carcinoma (HNSCC). HPV's involvement has alluded to better survival and prognosis in patients and suggests that different treatment strategies may be appropriate for them. Only some data on the epidemiology of HPV infection in the oropharyngeal, oral cavity, and laryngeal SCC exists in Europe. Thus, this study was carried out to investigate HPV's impact on HNSCC patient outcomes in the Irish population, one of the largest studies of its kind using consistent HPV testing techniques. A total of 861 primary oropharyngeal, oral cavity, and laryngeal SCC (OPSCC, OSCC, LSCC) cases diagnosed between 1994 and 2013, identified through the National Cancer Registry of Ireland (NCRI), were obtained from hospitals across Ireland and tested for HPV DNA using Multiplex PCR Luminex technology based in and sanctioned by the International Agency for Research on Cancer (IARC). Both overall and cancer-specific survival were significantly improved amongst all HPV-positive patients together, though HPV status was only a significant predictor of survival in the oropharynx. Amongst HPV-positive patients in the oropharynx, surgery alone was associated with prolonged survival, alluding to the potential for de-escalation of treatment in HPV-related OPSCC in particular. Cumulatively, these findings highlight the need for continued investigation into treatment pathways for HPV-related OPSCC, the relevance of introducing boys into national HPV vaccination programs, and the relevance of the nona-valent Gardasil-9 vaccine to HNSCC prevention.

RESUMO

The long-term impacts of Adverse Childhood Experiences (ACEs) are of increasing interest to researchers and practitioners, including the effectiveness of screening for ACEs to improve health and social outcomes. Despite a focus on implementing such practices, there has been little focus on ACEs experiences for women experiencing domestic violence and substance use, or consideration of practice responses around ACEs routine enquiry for domestic violence and related services. The Irish study discussed in this paper used an action research approach to implement ACEs routine enquiry within a domestic violence service for women accessing the service (n = 60), while also utilizing co-operative inquiry groups for practitioners both within the organization (n = 10) and with those working in associated fields of infant mental health, child protection, substance misuse and welfare and community support (n = 7). Of the 60 women who completed the ACEs routine enquiry in the study, over one-half (58 per cent) reported experiencing at least two ACEs in their childhood, including one-third of all respondents reporting experiencing four or more; service users reported significant levels of overlap between direct child maltreatment and adverse home environments. Reported parental substance misuse with the home environment was substantially higher than in general population studies. These findings offered early indications of both ACEs prevalence as well the types of ACEs that most define the experiences of the women presenting to a domestic violence service that supports women with substance misuse and other related issues. This paper discusses the ways in which the co-operative inquiry groups used this information and other processes to enhance practitioner, organizational, and inter-agency understanding and service responses. The practitioners felt that this form of ACEs routine enquiry, while not an end in itself, was a useful tool to engage women in conversations about trauma and intergenerational patterns and a basis for developing trauma-informed interventions. We conclude with discussion about: considerations of the risks of "individualizing" women's traumatic experiences; skills and supports for practitioners; and resource implications.

RESUMO

Diabetic cardiomyopathy (DCM) is characterized by structural and functional changes in the myocardium. Several studies have revealed that myocardial apoptosis and fibrosis occur during DCM. Studies have also indicated that oxidative stress may be a major factor associated with the development of DCM. Protein kinase C (PKC)ß2 has been demonstrated to be activated in diabetic rats, and overexpression of PKCß2 in the myocardium may result in cardiac hypertrophy and fibrosis. The P66shc adaptor protein, which is mediated by PKCß, serves an important role in apoptosis during oxidative stress. The aim of the present study was to investigate whether the PKCß2/P66shc oxidative stress pathway is associated with DCM, and to investigate the role and mechanisms of carvedilol in preserving cardiac function. Experimental diabetic rat models were induced by streptozotocin treatment accompanied by high energy intake. Carvedilol was orally administrated at a dose of 1 or 10 mg/kg/day. Cardiac function was evaluated by serum N-terminal pro-B-type natriuretic peptide level and cardiac ultrasound. Myocardial inflammation, oxidative stress, apoptosis and fibrosis were assessed by histopathological and echocardiographic analyses and tests for oxidative markers. Associated proteins and factors were examined by immunohistochemical and western blot analyses. Rats in the diabetes mellitus group exhibited significantly decreased systolic cardiac function along with elevated expression levels of phosphorylated (p)-PKCß2, phos-P66shc, caspase-3, malondialdehyde, collagen type I, tumor necrosis factor-α and interleukin-1ß, which were accompanied by disorder in metabolic processes. Treatment with carvedilol reversed these changes. Thus, the present results suggest that the PKCß2/P66shc signaling pathway may be associated with diabetic cardiomyopathy; furthermore, carvedilol, as a novel ß-receptor blocker, may protect the myocardium from injury by suppressing the myocardial inflammatory response, fibrosis, P66shc-mediated oxidative stress and subsequent apoptosis in myocardial tissue. Consequently, carvedilol may have potential as a therapy for the treatment of DCM.

RESUMO

INTRODUCTION: Knowledge of pharmacology is essential for dental students and for its safe application in the clinical environment. AIMS: The goals of our study were to assess dental students' performances in pharmacology with and without shared instruction, to investigate correlations between students' final grades in pre-clinical and clinical pharmacology, to determine if gender affects test performance and to explore characteristics of effective dental student learning. METHODS: A 9 year mixed method study was undertaken comprising (i) quantitative analysis of undergraduate performances in basic and clinical pharmacology (n = 320) and (ii) quantitative and qualitative exploration of student perceptions on teaching and learning in pharmacology. RESULTS: Mean basic pharmacology scores were not significantly different when dental students were co-taught with medical and pharmacy students. Regression analysis showed a statistically significant correlation (r = 0.582, P < 0.01) between basic and clinical pharmacology dental student scores. Interestingly, correlation was independent of gender with female student scores demonstrating a correlation of r = 0.480, P < 0.01 and males a correlation of 0.684, P < 0.01. Quantitative and qualitative feedback highlighted four thematic areas of effective dental student learning namely: (i) quality of instructors, (ii) lecture content, (iii) assessment type and (iv) learning environment. CONCLUSIONS: Teaching basic pharmacology in a multidisciplinary environment did not adversely affect dental students' examination performances. Dental students who perform well in basic pharmacology perform similarly well in clinical pharmacology. However, whether students' understanding and the application of pharmacology affects the quality of patient care in the clinical environment awaits further investigation.

RESUMO

This study aims to determine the survival impact of patient characteristics and treatment options associated with the early stage oral cavity squamous cell carcinoma, OCSCC. The methods are analysis of Irish cancer database examining T1/2, N0, and M0 cases of OCSCC from 1997 to 2007 inclusive. In total, 397 cases were identified. Anterolateral tongue accounted for 52.9 % of cases. Increased age at diagnosis and smoking are independent prognostic survival indicators associated with poorer outcomes. Surgery as the initial intervention was associated with significantly better survival outcomes, while surgery and adjuvant radiotherapy significantly worse outcomes. Surgical intervention is recommended as the first-line treatment in the early stage OCSCC in combination with elective neck dissection.

RESUMO

OBJECTIVE: To explore and compare the perfusion pattern of oral mucosa on Han Chinese and Caucasian by laser-doppler flowmetry. METHODS: A cross-sectional study was carried out, in 20 healthy Han Chinese adult subjects (average age: 28.4 years) and 20 healthy Caucasian (average age: 25.3 years) adult subjects, either gender with 10 subjects. Gingival perfusion was evaluated at 8 points (including upper incisor labial gingival, lower incisor labial gingival, palatal mucosa, cheek mucosa) using a laser-doppler flowmetry(O2C, Medizintechnik GmbH, Germany). Each measurement was carried out 25 seconds consisting 5 seconds of fore period and 20 seconds of work period, without pressure. The measurements were taken by two well- trained doctors, each measurement was exammed 3 times by an examiner, and the average value was recorded as final data. Each measurement has 4 parame ters: SpO2(oxygen saturation), rHB (relative amount of hemoglobin), flow (the blood flow of unit interval), and velocity (blood flow velocity). We compared the data by different sites, different genders, and different races. RESULTS: For palatal gingival, the average SpO2 was 77.1%±10.9%, the average rHB 67.8±11.1, and the average flow 194.1±63.7, which presented significant lower values than other oral mucosa. There was no significant difference among other sites. There was some significant difference between the Caucasian and the Han Chinese: the maxillary central incisor oxygen saturation (SpO2) which were averages of 75.6%±8.2% and 70.4%±7.6%; buccal mucosa hemoglobin (rHB) averages of 79.9±5.8 and 83.5±6.6, which had statistical differences. For most measurement points, the oxygen saturation on men was lower than that on women, which had significant difference. CONCLUSION: To investigate microcirculation pattern, oral mucosa can be the good observation site. Laser-doppler flowmetry is a well-documented instrument to survey on microcirculation.There may be differences between the genders in hemoglobin oxygen-binding capacity, which may have some impact on the ability of soft tissue healing. Oral mucosa display more blood perfusion than attached gingival. As the recipient site of gingival graft, maxilla and mandible have slight difference in blood supply.

RESUMO

A sense of fairness plays a critical role in supporting human cooperation. Adult norms of fair resource sharing vary widely across societies, suggesting that culture shapes the acquisition of fairness behaviour during childhood. Here we examine how fairness behaviour develops in children from seven diverse societies, testing children from 4 to 15 years of age (n = 866 pairs) in a standardized resource decision task. We measured two key aspects of fairness decisions: disadvantageous inequity aversion (peer receives more than self) and advantageous inequity aversion (self receives more than a peer). We show that disadvantageous inequity aversion emerged across all populations by middle childhood. By contrast, advantageous inequity aversion was more variable, emerging in three populations and only later in development. We discuss these findings in relation to questions about the universality and cultural specificity of human fairness.

RESUMO

Prostate cancer continues to be a major cause of morbidity and mortality in men, but a method for accurate prognosis in these patients is yet to be developed. The recent discovery of altered endosomal biogenesis in prostate cancer has identified a fundamental change in the cell biology of this cancer, which holds great promise for the identification of novel biomarkers that can predict disease outcomes. Here we have identified significantly altered expression of endosomal genes in prostate cancer compared to non-malignant tissue in mRNA microarrays and confirmed these findings by qRT-PCR on fresh-frozen tissue. Importantly, we identified endosomal gene expression patterns that were predictive of patient outcomes. Two endosomal tri-gene signatures were identified from a previously published microarray cohort and had a significant capacity to stratify patient outcomes. The expression of APPL1, RAB5A, EEA1, PDCD6IP, NOX4 and SORT1 were altered in malignant patient tissue, when compared to indolent and normal prostate tissue. These findings support the initiation of a case-control study using larger cohorts of prostate tissue, with documented patient outcomes, to determine if different combinations of these new biomarkers can accurately predict disease status and clinical progression in prostate cancer patients.

RESUMO

The prognosis of epithelial ovarian cancer is poor in part due to the high frequency of chemoresistance. Recent evidence points to the Toll-like receptor-4 (TLR4), and particularly its adaptor protein MyD88, as one potential mediator of this resistance. This study aims to provide further evidence that MyD88 positive cancer cells are clinically significant, stem-like and reproducibly detectable for the purposes of prognostic stratification. Expression of TLR4 and MyD88 was assessed immunohistochemically in 198 paraffin-embedded ovarian tissues and in an embryonal carcinoma model of cancer stemness. In parallel, expression of TLR4 and MyD88 mRNA and regulatory microRNAs (miR-21 and miR-146a) was assessed, as well as in a series of chemosensitive and resistant cancer cells lines. Functional analysis of the pathway was assessed in chemoresistant SKOV-3 ovarian cancer cells. TLR4 and MyD88 expression can be reproducibly assessed via immunohistochemistry using a semi-quantitative scoring system. TLR4 expression was present in all ovarian epithelium (normal and neoplastic), whereas MyD88 was restricted to neoplastic cells, independent of tumour grade and associated with reduced progression-free and overall survival, in an immunohistological specific subset of serous carcinomas, p<0.05. MiR-21 and miR-146a expression was significantly increased in MyD88 negative cancers (p<0.05), indicating their participation in regulation. Significant alterations in MyD88 mRNA expression were observed between chemosensitive and chemoresistant cells and tissue. Knockdown of TLR4 in SKOV-3 ovarian cells recovered chemosensitivity. Knockdown of MyD88 alone did not. MyD88 expression was down-regulated in differentiated embryonal carcinoma (NTera2) cells, supporting the MyD88+ cancer stem cell hypothesis. Our findings demonstrate that expression of MyD88 is associated with significantly reduced patient survival and altered microRNA levels and suggest an intact/functioning TLR4/MyD88 pathway is required for acquisition of the chemoresistant phenotype. Ex vivo manipulation of ovarian cancer stem cell (CSC) differentiation can decrease MyD88 expression, providing a potentially valuable CSC model for ovarian cancer.

RESUMO

BACKGROUND: Efficacy of simulators in teaching central venous catheterization (CVC) in an internal medicine residency program is unknown. OBJECTIVE: To determine whether or not learning CVC on simulators is associated with improvement in performance of CVC, knowledge about the procedure, and self-reported confidence. METHODS: All consenting first-year internal medicine residents who completed training in CVC on simulators were included. Participants were evaluated pre- and post-training by video-recorded CVC insertion and multiple-choice knowledge assessments. Procedural technique was rated in a blinded fashion by two independent adjudicators. Knowledge retention and self-reported confidence were reassessed at 18 months. MEASUREMENTS: Primary outcome of CVC performance was assessed based on global rating score (minimum 1, maximum 5). Secondary measures include checklist score (out of ten), knowledge score and self-reported confidence (6-point Likert scale ranging from "none" to "complete"). RESULTS: Median global rating scores in 30 participants increased from 3.5 (IQR = 3-4) to 4.5 (IQR = 4-4.5) (P < 0.001). Checklist score increased from 9 (IQR = 6-9.5) to 9.5 (IQR = 9-9.5) (P < 0.001). Knowledge score increased from 65.7 +/- 11.9% to 81.2 +/- 10.7% (P < 0.001). Confidence increased from 3 ("moderate", IQR = 2-3) to 4 ("good", IQR=3-4) (P < 0.001). Sixteen participants completed the retention tests. Improvement in knowledge score and confidence at 18 months was retained compared with baseline (P = 0.002 and P < 0.0001 respectively). CONCLUSIONS: Use of simulators in teaching CVC in an internal medicine residency program results in improved procedural performance, knowledge, and self-reported confidence. Improvement in knowledge and confidence was retained at 18 months.

RESUMO

BACKGROUND: Many standardized patient (SP) encounters employ SPs without physical findings and, thus, assess physical examination technique. The relationship between technique, accurate bedside diagnosis, and global competence in physical examination remains unclear. METHOD: Twenty-eight internists undertook a cardiac physical examination objective structured clinical examination, using three modalities: real cardiac patients (RP), "normal" SPs combined with related cardiac audio-video simulations, and a cardiology patient simulator (CPS). Two examiners assessed physical examination technique and global bedside competence. Accuracy of cardiac diagnosis was scored separately. RESULTS: The correlation coefficients between participants' physical examination technique and diagnostic accuracy were 0.39 for RP (P < .05), 0.29 for SP, and 0.30 for CPS. Patient modality impacted the relative weighting of technique and diagnostic accuracy in the determination of global competence. CONCLUSIONS: Assessments of physical examination competence should evaluate both technique and diagnostic accuracy. Patient modality affects the relative contributions of each outcome towards a global rating.

RESUMO

AIM: To examine the relationship between a physician's ability to examine a standardized patient (SP) and their ability to correctly identify related clinical findings created with simulation technology. METHOD: The authors conducted an observational study of 347 candidates during a Canadian national specialty examination at the end of post-graduate internal medicine training. Stations were created that combined physical examination of an SP with evaluation of a related audio-video simulation of a patient abnormality, in the domains of cardiology and neurology. Examiners evaluated a candidate's competence at performing a physical examination of an SP and their accuracy in diagnosing a related audio-video simulation. RESULTS: For the cardiology stations, the correlation between the physical examination scores and recognition of simulation abnormalities was 0.31 (p < 0.01). For the neurology stations, the correlation was 0.27 (p < 0.01). Addition of the simulations identified 18% of 197 passing candidates on the cardiology stations and 17% of 240 passing candidates on the neurology stations who were competent in their physical examination technique but did not achieve the passing score for diagnostic skills. CONCLUSIONS: Assessments incorporating SPs without physical findings may need to include other methodologies to assess bedside diagnostic acumen.

RESUMO

PURPOSE: To evaluate the reliability and validity of the Mini-Clinical Evaluation Exercise (mini-CEX) for postgraduate year 4 (PGY-4) internal medicine trainees compared to a high-stakes assessment of clinical competence, the Royal College of Physicians and Surgeons of Canada Comprehensive Examination in Internal Medicine (RCPSC IM examination). METHODS: Twenty-two PGY-4 residents at the University of British Columbia and the University of Calgary were evaluated, during the 6 months preceding their 2004 RCPSC IM examination, with a mean of 5.5 mini-CEX encounters (range 3-6). Experienced Royal College examiners from each site travelled to the alternate university to assess the encounters. RESULTS: The mini-CEX encounters assessed a broad range of internal medicine patient problems. The inter-encounter reliability for the residents' mean mini-CEX overall clinical competence score was 0.74. The attenuated correlation between residents' mini-CEX overall clinical competence score and their 2004 RCPSC IM oral examination score was 0.59 (P = 0.01). CONCLUSION: By examining multiple sources of validity evidence, this study suggests that the mini-CEX provides a reliable and valid assessment of clinical competence for PGY-4 trainees in internal medicine.

RESUMO

AIM: To analyze the attitudes of the Guinean and of the Ivory Coast communities leading to delayed consultation despite apparent malformations in children. PATIENTS AND METHODS: From January 1, 2000 to December 31, 2002, we carried out a prospective investigation in the paediatric surgery units of the Donka teaching hospital (Conakry) and Cocody, Treichville and Yopougon (Abidjan) teaching hospital. One hundred and two children affected with apparent malformations were included. The studied variables were: age, sex, ethnos group, religion, socio-economic level and the cultural designs of the families. RESULTS: Sex ratio male/female was 1,5 and the average age at first consultation was 17 months. Seventy-six per cent of the children carrying apparent malformations at birth were seen at an age ranging from 1 to 30 months. Orthopaedic malformations were prominent (44%) and led especially to negative reactions of the entourage of the patients. Some religious beliefs took a part of the delayed consultation and impaired relationships between the 2 parents. The low socio-economic level (54%) was determining in the delayed consultation. The birth of a child with malformation in the malinké, akan krou community could be understood like a parchment from a god or a witchcraft. CONCLUSION: The contributive factors of the delay to the consultation of the children carrying apparent malformations in the communities Guinean and of the Ivory Coast are poverty, ignorance and some religious beliefs. Education and well understanding of these reasons in developing country should improve the acceptance and taking care of these children as well as the development of medical insurance system.
