Aim: To clarify the clinicopathological features in elderly anaplastic lymphoma kinase (ALK) rearranged non-small cell lung cancer (NSCLC) patients.
Patients And Methods: A retrospective study was performed in 129 ALK rearranged NSCLC patients diagnosed between April 2008 and March 2019 in fifteen Institutions of the Ibaraki prefecture, Japan.
Results: Median age of patients was 63 years. In 59 patients aged 65 and older, the proportions of patients with advanced stage and those treated with ALK-tyrosine kinase inhibitor (TKI) were lower than those younger than 65 years. There was no difference in overall survival (OS) between the two age groups. Among the elderly patients, no difference was observed in OS between the patients aged 65-69 and those aged 70 and older. In 89 patients treated with TKI, no significant differences were observed in the progression-free survival of TKIs and OS between patients aged 65 and older and those younger than 65, respectively.
Conclusion: Evaluation of ALK gene status and TKI treatment are desirable even for elderly patients.

Background: Under-5 children have been known to bear a significant burden of malaria in endemic countries. Though significant progress has been made towards malaria prevention and control in Nigeria, it is expected that the addition of new malaria prevention strategy, such as perennial malaria chemoprevention (PMC) can contribute to a more rapid decline in malaria cases. This study aimed to determine the prevalence and factors associated with malaria and anaemia among children aged 2-18 months in Osun State.

Background: Choosing effective devices (inhaled corticosteroid [ICS]-long-acting β2 agonist [LABA] combination inhalers) as maintenance treatment is critical for managing patients with asthma. We aimed to compare ICS/LABA combination efficacy, safety, and adherence across inhaler types and components in patients newly diagnosed with asthma.
Methods: Utilizing South Korea's National Health Insurance Service data, we conducted a population-based cohort study involving patients aged 18-80 years, newly diagnosed with asthma who received ICS/LABA combination therapy between January 2016 and December 2020.
Establishment and validation of predictive model of ARDS in critically ill patients.

Department of Critical Care Medicine, Peking University Third Hospital, Beijing, 100191, China.
Background: Acute respiratory distress syndrome (ARDS) is a prevalent complication among critically ill patients, constituting around 10% of intensive care unit (ICU) admissions and mortality rates ranging from 35 to 46%. Hence, early recognition and prediction of ARDS are crucial for the timely administration of targeted treatment. However, ARDS is frequently underdiagnosed or delayed, and its heterogeneity diminishes the clinical utility of ARDS biomarkers.

Background: Breast cancer screening in Aotearoa New Zealand (NZ) still has persistent inequitable coverage by ethnicity, especially for Indigenous Māori women. This project aimed to undertake systematic data linkage to identify and invite eligible Māori women to participate in breast screening.
Methods: This is a cross-sectional observational study conducted in Northern New Zealand between 1/01/2020 and 30/06/2021.
Mortality and morbidity patterns in Yaoundé, Cameroon: an ICD-11 classification-based analysis.
BMC Med Inform Decis Mak
January 2025
Higher Institute of Medical Technology, Yaoundé, Cameroon.
Background: In Cameroon, like in many other resource-limited countries, data generated by health settings including morbidity and mortality parameters are not always uniform. In the absence of a national guideline necessary for the standardization and harmonization of data, precision of data required for effective decision-making is therefore not guaranteed. The objective of the present study was to assess the reporting style of morbidity and mortality data in healthcare settings.
