RESUMEN
OBJECTIVE: This prospective observational study explored the effect of early onset hypoalbuminemia (EOH) on the development of adult respiratory distress syndrome (ARDS) in orthopedic trauma victims. METHODS: Serum albumin levels were measured for the initial 7 days of injury for adult trauma patients (18-65 years). Patients were recruited into group A (any serum albumin value < 3.5 mg/dl) and group B (all serum albumin ≥ 3.5 mg/dl), based on serum albumin values. Patients were followed for the development of ARDS and outcome until 28 days. The primary outcome of the study was to explore the effects of EOH on ARDS. RESULTS: EOH (any serum albumin value < 3.5 g/dl within 7 days of injury) was present in 205/386 (53.1%) patients. The majority of 174/205 (84.9%) patients had EOH by the fourth day after the injury, with the mean time for development of EOH being 2.15 ± 1.87 days. ARDS manifested in 87/205 (42.4%) and 15/181 (8.3%) patients in group A and group B, respectively (p < 0.001). EOH had 8.2 times greater odds of ARDS (OD 8.2 95% CL 4.7-14.0, p = 0.000). The mean time for the onset of ARDS was 5.63 ± 2.62 days. No statistically significant causal relationship occurred between the onset of EOH and the development of ARDS (Pearson's correlation coefficient = 0.14, p = 0.16). At serum albumin cutoff concentrations of 3.4 gm/dl on D1 (AUC 0.68, 95% CI: 0.61-0.74, p = 0.000), ARDS may be anticipated in 62.8% of patients. The commencement of ARDS was independently correlated with EOH (p = 0.000), Respiratory rate on admission (p = 0.000), inotrope use (p = 0.000), and soft tissue injury (p = 0.000) (R2 = 0.466). The odds of 28-day all-cause death were 7.7 times higher in EOH (OD 7.7 95% CL 3.5-16.7, p = 0.00) and 9 times higher in ARDS (OD 9 95% CL 4.9-16.16, p = 0.00). CONCLUSION: EOH is a frequent occurrence and has a strong influence development of ARDS and 28-day mortality in trauma patients.

BACKGROUND: Individuals with cancer are being given increasing responsibility for the self-management of their health and illness. In other chronic diseases, individuals who experience treatment burden are at risk of poorer health outcomes. Less is known about treatment burden and its impact on individuals with cancer. This systematic review investigated perceptions of treatment burden in individuals living with and beyond cancer. METHODS AND FINDINGS: Medline, CINAHL and EMBASE databases were searched for qualitative studies that explored treatment burden in individuals with a diagnosis of breast, prostate, colorectal, or lung cancer at any stage of their diagnostic/treatment trajectory. Descriptive and thematic analyses were conducted. Study quality was assessed using a modified CASP checklist. The review protocol was registered on PROSPERO (CRD42021145601). Forty-eight studies were included. Health management after cancer involved cognitive, practical, and relational work for patients. Individuals were motivated to perform health management work to improve life-expectancy, manage symptoms, and regain a sense of normality. Performing health care work could be empowering and gave individuals a sense of control. Treatment burden occurred when there was a mismatch between the resources needed for health management and their availability. Individuals with chronic and severe symptoms, financial challenges, language barriers, and limited social support are particularly at risk of treatment burden. For those with advanced cancer, consumption of time and energy by health care work is a significant burden. CONCLUSION: Treatment burden could be an important mediator of inequities in cancer outcomes. Many of the factors leading to treatment burden in individuals with cancer are potentially modifiable. Clinicians should consider carefully what they are asking or expecting patients to do, and the resources required, including how much patient time will be consumed.

AIMS: The HLA system has been implicated as an underlying determinant for modulating the immune response to SARS-CoV-2. In this study, we aimed to determine the association of patients' HLA genetic profiles with the disease severity of COVID-19 infection. METHODS: Prospective study was conducted on COVID-19 patients (n = 40) admitted to hospitals in Saskatoon, Canada, between March and December 2020. Next-generation sequencing was performed on the patient samples to obtain high-resolution HLA typing profiles. The statistical association between HLA allelic frequency and disease severity was examined. The disease severity was categorized based on the length of hospital stay and intensive care needs or demise during the hospital stay. RESULTS: HLA allelic frequencies of the high and low-severity cohorts were normalized against corresponding background allelic frequencies. In the high-severity cohort, A*02:06 (11.8-fold), B*51:01 (2.4-fold), B*15:01(3.1-fold), C*01:02 (3.3-fold), DRB1*08:02 (31.2-fold), DQ*06:09 (11-fold), and DPB1*04:02(4-fold) were significantly overrepresented (p < 0.05) making these deleterious alleles. In the low-severity cohort, A*24:02 (2.8-fold), B*35:01 (2.8-fold), DRB1*04:07 (5.3-fold), and DRB1*08:11 (22-fold) were found to be significantly overrepresented (p < 0.05) making these protective alleles. These above alleles interact with NK cell antiviral activity via the killer immunoglobulin-like receptors (KIR). The high-severity cohort had a higher predilection for HLA alleles associated with KIR subgroups; Bw4-80I (1.1-fold), and C1 (1.6-fold) which promotes NK cell inhibition, while the low-severity cohort had a higher predilection for Bw4-80T (1.6-fold), and C2 (1.6-fold) which promote NK cell activation. CONCLUSION: In this study, the HLA allelic repository with the distribution of deleterious and protective alleles was found to correlate with the severity of the clinical course in COVID-19. Moreover, the interaction of specific HLA alleles with the KIR-associated subfamily modulates the NK cell-mediated surveillance of SARS-CoV-2. Both deleterious HLA alleles and inhibitory KIR appear prominently in the severe COVID-19 group focusing on the importance of NK cells in the convalescence of COVID-19.
