The effects of age on clinical characteristics, hospitalization and mortality of patients with influenza-related illness at a tertiary care centre in Malaysia.

ABSTRACT: BACKGROUND:Age is an established risk factor for poor outcomes in individuals with influenza-related illness, and data on its influence on clinical presentations and outcomes in the South-East Asian settings are scarce. The aim of this study was to determine the above among adults with influenza-related upper respiratory tract infection at a teaching hospital in Malaysia. METHODS:A retrospective case-note analysis was conducted on a cohort of 3935 patients attending primary care at the University Malaya Medical Centre, Malaysia from February 2012 till May 2014 with URTI symptoms. Demographics, clinical characteristics, medical and vaccination history were obtained from electronic medical records, and mortality data from the National Registration Department. Comparisons were made between those aged <25, ?25 to <65 and ?65 years. RESULTS:470 (11.9%) had PCR-confirmed influenza virus infection. Six (1.3%) received prior influenza vaccination. Those aged ?65 years were more likely to have ?2 comorbidities (P < .001) and were less likely to present with fever (P = .004). One-third of those aged ?65 years experienced hospitalization, intensive care admission or death within a year compared to 10% in the ?25 to <65 years. Age ?65 years was an independent predictor of hospitalization and death (OR = 9.97; 95% CI = 3.11-31.93) compared to those aged <25 years. CONCLUSION:Older patients in our cohort were more likely to have comorbidities and present with atypical features, with older age being an independent predictor of poor health outcomes. Our findings will now inform future health policies on older persons and economic modelling of adult vaccination programmes.

Project description:ObjectiveThe paucity of specialised care in the peripheral areas of developing countries necessitates the referral of sick neonates to higher centres. Organised interhospital transport services provided by a skilled and well-equipped team can significantly improve the outcome. The present study evaluated the transport characteristics and predictors of mortality among neonates referred to a tertiary care centre in North India.DesignProspective observational study.SettingsTertiary care teaching hospital in North India.Patients1013 neonates referred from peripheral health units.Main outcome measuresMortality among referred neonates on admission to our centre.ResultsOf the 1013 enrolled neonates, 83% were transferred through national ambulance services, 13.7% through private hospital ambulances and 3.3% through personal vehicles. Major transfer indications were prematurity (35%), requirement for ventilation (32%), birth asphyxia (28%) and hyperbilirubinaemia (19%). Hypothermia (32.5%, 330 of 1013), shock (19%, 192 of 1013) and requirement for immediate cardiorespiratory support (ICRS) (10.4%, 106 of 1013) on arrival were the major complications observed during transfer. A total of 305 (30.1%, N=1013) deaths occurred. Of these, 52% (n=160) died within 24 hours of arrival. On multivariate logistic analysis, unsupervised pregnancy (<4 antenatal visits; p=0.037), antenatal complications (p<0.001), prematurity ≤30 weeks (p=0.005), shock (p=0.001), hypothermia (p<0.001), requirement for ICRS on arrival (p<0.001), birth asphyxia (p=0.004), travel time >2 hours (p=0.005) and absence of trained staff during transfer (p<0.001) were found to be significant predictors of mortality.ConclusionThe present study depicts high mortality among infants referred to our centre. Adequate training of peripheral health personnel and availability of pre-referral stabilisation and dedicated interhospital transport teams for sick neonate transfers may prove valuable interventions for improved outcomes.

Project description:BackgroundThere is a remarkable dearth of literature on less pronounced outcomes in malaria, namely prolonged hospitalization and intensive care requirement. Limitations on routine clinical applicability of the World Health Organization's (WHO) guidelines for determination of severity in malaria does result in underestimation of the true burden of clinicians' perceived severity in malaria. This study was conducted to evaluate the clinico-laboratory and malarial severity features to determine their association with mortality, prolonged hospitalization and requirement of intensive care outcomes.MethodsA tertiary care hospital based retrospective study was conducted from the year 2007 to 2011 among microscopically proven adult malaria patients. Logistic regression analysis was performed to determine the factors associated with mortality, more than seven days hospitalization, intensive care and other supportive requirements.ResultsOf a total of 922 malaria cases studied, more than seven days of hospitalization was the most frequent outcome (21.8% (201), 95% CI=19.1-24.5%) followed by intensive care requirement (8.6% (79), 95% CI=6.8-10.4%) and in-hospital mortality (1.2% (11), 95% CI=0.5-1.9%). Odds of mortality were significantly higher with cerebral malaria, pulmonary oedema/acute respiratory distress syndrome (PE/ARDS), liver dysfunction, severe anaemia, renal failure, respiratory distress, metabolic acidosis and leucocytosis. More than seven days hospitalization had inverse association with mortality. Plasmodium falciparum infection, more than three days of history of fever, haemoglobinuria, renal failure, shock, leucocytosis, severe thrombocytopaenia and every 10 mmHg fall in systolic blood pressure were the independent predictors of more than seven days of hospitalization. More than three days of history of fever, cerebral malaria, PE/ARDS, renal failure, metabolic acidosis, hyperparasitaemia, leucocytosis and severe thrombocytopaenia were independently associated factors with intensive care requirement.ConclusionsFor routine clinical settings, severity definition for malaria needs to be redefined or modified from the existing WHO guidelines. Leucocytosis and severe thrombocytopaenia should be identified as severity determinant in malaria. Patients having more than three days history of fever, leucocytosis, severe thrombocytopaenia and renal failure are more likely to require either prolonged hospitalization and/or intensive care. PE/ARDS alone in Plasmodium vivax may result in mortality, whereas multiorgan involvement is common in P. falciparum related mortalities.

Project description:BackgroundMultiple Myeloma (MM) is characterized by the presence of clonal plasma cells. These often result in complications including bone destruction, hypercalcemia, renal insufficiency, and anaemia. Induction with a triplet or quadruplet regimen followed by autologous stem cell transplantation (ASCT) has been the standard of care for transplant eligible patients to achieve durable remission.PurposeThis is a retrospective analytical study to determine the outcome of Multiple Myeloma patients who underwent ASCT in Ampang Hospital.Materials and methodsWe included a 5-year cohort of patients transplanted from 1st July 2014 to 30th June 2019. Data were obtained through electronic medical records. Prognostic factors for progression-free survival (PFS) and overall survival (OS) were analyzed using simple and multiple Cox proportional hazard regression analysis. All analyses were done using software R version 3.6.2 with validated statistical packages.Results139 patients were analyzed. The median age at transplant was 56 years old and 56.1% are males (n＝78). The most common subtype is IgG Kappa (n＝67, 48.2%). Only 93 patients in which the International Staging System (ISS) could be determined, and among them, 33.3% of patients (n＝31) have advanced stage Ⅲ disease. The most common induction received before ASCT was a bortezomib based regimen and/or an immunomodulatory (IMiD) based regimen. 63.3% of patients achieved at least a very good partial response (VGPR) before ASCT. Most patients received myeloablative conditioning (MAC) (n＝119, 85.6%). The mean cell dose is 3.68×106/kg. The median time to engraftment was 11 days for both platelet and absolute neutrophil count (ANC). With the median follow-up of 17.3 (range, 6.2-33.4) months, the median OS and PFS were not reached. The 1-year and 2-year PFS were 75% (95% CI 66-82%) and 52% (95% CI 42-62%), respectively. The 1-year and 2-year OS were 82% (95% CI 74-88%) and 70% (95% CI 60-78%), respectively. 6 patients (4.3%) had transplant-related mortality (TRM). IgA subtype was found to adversely affect PFS. Maintenance therapy and the absence of renal impairment was associated with better PFS and OS.Discussion and conclusionsOur study found that ASCT following induction treatment is safe and beneficial to achieve a deeper remission status. In our study, the addition of maintenance therapy is associated with an improved outcome in PFS and OS.
