Determination of Liver Function Tests and Liver Ultrasonographic Findings in Patients with Leptospirosis in a Tertiary Hospital.

Introduction: Leptospirosis is an important zoonotic disease commonly found in tropical or sub-tropical countries. The most severe form is Weil's syndrome which presents with jaundice, renal failure, and bleeding diatheses. Although jaundice occurs in 38% of patients with leptospirosis, no studies in Asia have focused on the liver biochemical profile of these patients. Characterization of liver biochemical profile and ultrasonographic findings may shed more light on the disease process. Identification of liver biochemical parameters that portend a poor prognosis may also allow for early aggressive intervention. Objective: To describe the liver biochemical profile and liver ultrasonographic findings in adult patients with laboratory-confirmed leptospirosis, admitted at a tertiary hospital in Manila, Philippines. The association of clinical and laboratory features with clinical outcomes (i.e., severe liver injury, Weil's syndrome, and mortality) was also investigated. Methods: This retrospective cross-sectional study reviewed all available cases of adult patients with laboratory-confirmed leptospirosis admitted in the Philippine General Hospital from January 2009 to August 2018. The clinical features, liver biochemical profiles, and ultrasound findings were recorded and analyzed. Comparison between the means of each group based on clinical outcome (i.e., mortality, Weil's syndrome) was done via Students' t-test for continuous variables, and calculation of the Odds Ratio for categorical variables. Results: Total and direct bilirubin levels were elevated in patients with leptospirosis compared to serum amino-transferases and alkaline phosphatase levels which were only mildly elevated. Abdominal ultrasound showed typically un-enlarged livers with normal parenchymal echogenicity, normal spleens, and non-dilated biliary trees. Dyspnea was associated with an increased odds for mortality. Although jaundice was present in 39.5% of patients and significantly associated with severe liver injury, this was not associated with mortality. Liver biochemical test values did not differ among patients who expired and those who survived to discharge. The presence of myalgia and abdominal pain increased the odds for Weil's syndrome. Conclusion: To date, no local studies have fully described the liver biochemical profile of patients with leptospirosis. Our findings are compatible with previous studies showing that leptospirosis typically presents with predominantly elevated direct bilirubin from cholestasis and systemic infection. Contrary to previous literature, however, our study found no association between jaundice and mortality.

Epidemiology of early vs. Late recurrence among women with Early-Stage estrogen Receptor-Positive breast cancer in the pathways study.

BACKGROUND: Relatively little is known about the differences in prognostic factors for early vs late recurrence among women with early-stage estrogen receptor-positive (ER+) breast cancer. METHODS: We analyzed factors related to early (<5 years) vs late (≥5 years) recurrence in 2,992 women with stage I-IIB ER+ breast cancer in the Pathways Study, a prospective cohort of women with breast cancer enrolled between 2006 and 2013, with ascertainment of recurrence and death through December 2021. RESULTS: After a median follow-up of 13.3 years, 341 (13.8%) women had recurrences, including 181 (53.7%) with late recurrence. Higher stage and grade were associated with recurrence regardless of timing, whereas progesterone receptor (PR) negativity was associated with early but not late recurrence. Receipt of endocrine therapy was associated with reduced risk of overall recurrence, but the length of endocrine therapy was not significant in multivariable models. Minoritized racial and ethnic groups, including Asian, Black, and Hispanic women, had higher risk of early but not late recurrence, compared with non-Hispanic White women. The trend of higher risk of early recurrence among these groups remained after adjustment for clinical, demographic, and socioeconomic factors, but was statistically significant only in Asian women. CONCLUSIONS: Our study revealed potentially important distinctions for early vs late recurrence, including the associations with PR-negativity and self-identified race and ethnicity. Possible higher risk of early recurrence among Asian, Black, and Hispanic women provides novel evidence for the existence of disparities in cancer outcomes, even within the breast cancer subtype indicative of generally good prognosis.

Clinical, Epidemiologic, and Pathologic Significance of ERBB2-Low Expression in Breast Cancer.

Importance: It is unclear whether breast cancer (BC) with low ERBB2 expression (ERBB2-low) is a distinct clinical, pathological, and epidemiological entity from BC classified as no ERBB2 expression (ERBB2-negative). Objective: To evaluate the clinical, pathological, and epidemiologic features of BC with ERBB2-low expression compared with ERBB2-negative BC in a large population study. Design, Setting, and Participants: This cohort study was conducted as part of the Pathways Study, a prospective, racially and ethnically diverse cohort study of women with BC enrolled between 2006 and 2013 in Kaiser Permanente Northern California (KPNC). The hematoxylin and eosin slides underwent centralized pathology review, including the percentage of tumor infiltrating lymphocytes (TILs). Breast biomarker results were extracted from pathology reports, and women were included if they had a documented ERBB2 value that was not classified ERBB2-positive. Data were analyzed from February 2023 through January 2024. Exposure: Clinical and tumor characteristics associated with BC and ERBB2-low or ERBB2-negative status. Main Outcome and Measures: ERBB2-low was defined as immunohistochemistry score of 1+ or 2+ (negative by in situ hybridization); ERBB2-negative was defined as immunohistochemistry score of 0+. Other data were collected by self-report or extraction from electronic health records, including BC risk factors, tumor characteristics, treatment modality, and survival outcomes, with recurrence-free survival (RFS) as the primary outcome and overall survival (OS) and BC-specific mortality (BCSM) as secondary outcomes. The clinical, pathological, and epidemiological variables were compared between ERBB2-low and ERBB2-negative BC. Results: Of 2200 eligible patients (all female; with mean [SD] age, 60.4 [11.9] years), 1295 (57.2%) had tumors that were ERBB2-low. Hormone receptors were positive in 1956 patients (88.9%). The sample included 291 Asian patients (13.2%), 166 Black patients (7.5%), 253 Hispanic patients (11.5%), 1439 White patients (65.4%), and 51 patients (2.3%) who identified as other race or ethnicity (eg, American Indian or Alaska Native and Pacific Islander). Within the hormone receptor-negative group, patients whose tumors had ERBB2-low staining, compared with those with ERBB2-negative tumors, had better OS (hazard ratio [HR], 0.54; 95% CI, 0.33-0.91; P = .02), RFS (HR, 0.53; 95% CI, 0.30-0.95; P = .03), and BCSM (HR, 0.43; 95% CI, 0.22-0.84; P = .01). In multivariable survival analysis stratified by hormone receptor status and adjusted for key covariates, patients with ERBB2-low and hormone receptor-negative tumors had lower overall mortality (HR, 0.48; 95% CI, 0.27-0.83; P = .009), RFS (HR, 0.45; 95% CI, 0.24-0.86; P = .02), and BCSM (subdistribution HR, 0.21; 95% CI, 0.10-0.46; P < .001) compared with patients with ERBB2-negative and hormone receptor-negative tumors. Within the hormone receptor-negative subtype, patients with ERBB2-low and high TILs tumors had better survival across all 3 outcomes compared with patients with ERBB2-negative and low TILs tumors. Additionally, patients with ERBB2-low and low TILs tumors had better BCSM (subdistribution HR, 0.36; 95% CI, 0.14-0.92; P = .03). Conclusions and Relevance: These findings suggest that there were clinical, pathological, and epidemiological differences between ERBB2-low and ERBB2-negative BC, raising the possibility that ERBB2-low might be a unique biologic entity.

The Impact of Malnutrition on the Quality of Life of Colorectal Cancer Patients in a Tertiary Hospital.

Malnutrition among colorectal cancer patients can impair quality of life and decrease survival. This study evaluated the nutritional status of colorectal cancer patients and its association with quality of life among Filipino colorectal cancer patients seen in a tertiary hospital. A cross-sectional study was conducted among colorectal cancer patients seen at the Philippine General Hospital between December 1, 2019 and February 28, 2020. Nutritional status was evaluated using the Subjective Global Assessment, while quality of life was assessed using the EORTC QLQ-C30. Descriptive statistics, ANOVA and logistic regression were employed for analysis. Among 292 patients, malnutrition was noted in 76.4%. Stage III cancer had a higher odds for malnutrition (OR (odds ratio) = 6.22, 95% confidence interval (CI): 1.59, 24.42). Patients who received or were currently receiving chemotherapy were less likely to develop malnutrition (OR = 0.35, 95% CI: 0.18-0.69). Global health status and all functional subscale scores for the severely malnourished group were lower while the scores for symptom scales increased with the degree of malnutrition. There was a high prevalence of malnutrition among colorectal cancer patients and this was associated with poor quality of life. Future directions emphasizing early nutritional screening and assessment are recommended.

Metastatic prostate cancer mimicking a rectal cancer: a case report.

The most common presenting symptoms of prostate cancer, a common cancer in males worldwide, are lower urinary tract symptoms. In rare cases, however, urinary symptoms may not be apparent, and patients can present with gastrointestinal symptoms instead. Even rarer is the involvement of non-regional lymph nodes such as the cervical nodes. Here, we report a case of a 50-year-old male who initially presented with constipation and an enlarging left lateral neck mass. Further work-up revealed metastatic prostatic adenocarcinoma and the patient dramatically responded to chemotherapy, androgen deprivation therapy and bone support therapy. This case highlights the importance of considering a prostate malignancy in a male patient presenting with gastrointestinal symptoms and a neck mass even in the absence of lower urinary tract symptoms. Serum prostate specific antigen, pathologic findings and immunohistochemistry staining are important to guide the clinician in making the correct diagnosis and treatment.

Transdermal versus oral granisetron in controlling chemotherapy-induced nausea and vomiting: a meta-analysis.

PURPOSE: To compare the efficacy of transdermal granisetron versus oral granisetron in controlling chemotherapy-induced nausea and vomiting (CINV) in patients with cancer METHODS: Data sources were CENTRAL, MEDLINE, EMBASE, Clinicaltrials.gov , and Google Scholar. Inclusion criteria included randomized controlled trials comparing transdermal versus oral granisetron in patients with CINV. For data extraction, two authors independently analyzed the methodological quality and extracted data. A random effects model was used to estimate the risk ratio (RR) or odds ratio (OR) with 95% confidence interval (CI). RESULTS: Three studies (1086 patients) were included. Oral granisetron is superior (OR 0.77; 95% CI 0.60 to 0.99) to its transdermal form in achieving complete control of CINV in patients receiving chemotherapy. As for the risk of constipation (RR 1.32; 95% CI 0.73 to 2.40) and QTc prolongation (RR 0.17; 95% CI 0.02 to 1.40) as adverse effects, no statistically significant difference was observed between the two routes. CONCLUSION: Oral granisetron is better in achieving complete control of CINV in patients receiving chemotherapy. As for the risk of constipation and QTc prolongation as adverse effects, there was no statistically significant difference between the two routes.

Caring for the carers: safeguarding oncologists' mental health in the time of COVID-19.

Taking care of patients with chronic, terminal diseases presents unique challenges to the mental health of medical oncologists. The current coronavirus disease 2019 (COVID-19) pandemic has exacerbated these mental health risks brought about by isolation and exhaustion. Delegated to be a national COVID-19 referral centre, the University of the Philippines-Philippine General Hospital faced many challenges, including the increased workload in a perilous and anxiety-inducing national crisis which placed the entire healthcare team in an unprecedented situation. To adapt to these challenges, the Division of Medical Oncology employed the following measures to safeguard the mental health of its faculty and fellows: 1) use of psychological support materials; 2) initiation of a psychological intervention programme and 3) establishment of peer support programmes. Caring for the carers through evidence-based interventions ensures the delivery of quality care to our cancer patients despite the challenges during these trying times.
