Breast cancer is the most clinically relevant pathology of the mammary gland and is currently the most diagnosed malignant disease among women worldwide. In breast cancer prevention, it is important to consider that the risk of developing the disease is not the same for the entire population. This pathology presents heterogeneous clinical manifestations and the most common classification is related to the following hormonal receptors: estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and triple-negative (TNBC). Currently, a new class of therapy is being used for cancer treatment: anti-body-drug conjugates. A bibliographic search was performed by establishing keywords and then combining them using Boolean operators OR and AND. Thus, the search equation was formulated according to the PICO search question to be used in the PubMed database. Results: Fifteen studies that met the established inclusion criteria were analyzed, and their methodological quality was assessed using the Joanna Briggs Institute approach, demonstrating high reliability in the results obtained, the analyzed studies focus on the combination of adjuvant Pertuzumab + Trastuzumab with chemotherapy for the treatment of HER2-positive breast cancer. Scientific evidence suggests that the combination of pertuzumab and trastuzumab not only improves the survival of patients with HER2-positive breast cancer but also provides a safe and flexible treatment option.

Professional basketball entails high physical demands and a complex injury profile in which injury burden and time-loss distribution critically affect player availability. This study explored the association between preseason anthropometric body composition and in-season injury burden in male professional basketball and explored body phenotypes linked to greater injury accumulation. A retrospective longitudinal cohort design was applied using official injury records and standardized ISAK anthropometric assessments collected during preseason. Players from two male professional teams (first team, ACB; second team, LEB Plata) were included. Outcomes were the number of injuries and observed days lost during the season. Associations were assessed using Pearson correlations, principal component analysis (PCA), team-stratified logistic regression, and unsupervised k-means clustering. Injury burden demonstrated a highly skewed distribution, with a small subset of players accounting for a large proportion of total days lost. Preseason adiposity markers showed strong internal coherence, with PCA identifying a dominant component reflecting an adiposity gradient. Higher preseason body fat percentage was associated with a greater likelihood of high injury burden (≥3 injuries/season) in both teams. Clustering revealed two phenotypes: a higher-adiposity, higher-burden profile and a lower-adiposity, lower-burden profile. These exploratory findings suggest that preseason body composition, particularly adiposity, may be related to injury burden in male professional basketball. However, given the limited sample size and exploratory design, the results should be interpreted cautiously and considered hypothesis-generating. Precompetitive body phenotyping may therefore provide preliminary information for identifying players potentially at elevated risk of recurrent injury accumulation and reduced competitive availability.

Background and Objectives: Malnutrition and frailty affect 30–55% of intensive care unit (ICU) patients, yet formal nutritional screening remains inconsistently implemented in routine ICU admission workflows. The APACHE II score, the standard measure of acute physiological severity, does not capture pre-existing nutritional status or functional reserve. The Norton scale, routinely recorded by nursing staff for pressure-ulcer screening, could serve as a pragmatic proxy for the nutritional-functional axis. We assessed its independent prognostic value at admission for in-hospital and post-ICU mortality. Materials and Methods: Retrospective cohort study of 5775 consecutive adult patients admitted to a Spanish tertiary polyvalent ICU between 2012 and 2019, with APACHE II and Norton scores recorded at admission. The Norton was analysed as continuous and categorised (minimal >14, medium 13–14, high 10–12, very high 5–9). Discrimination was assessed by AUC and DeLong’s test, predictive improvement by IDI and NRI, and internal validity by bootstrap resampling (B = 200). Results: Hospital mortality was 12.8% (n = 738), rising from 7.7% in patients with minimal-risk Norton to 34.5% in very high risk. After adjustment for APACHE II, each additional Norton point reduced the odds of death by 7.7% (adjusted OR = 0.923; 95% CI 0.903–0.943). Adding the Norton to APACHE II improved discrimination (AUC 0.865 → 0.872; DeLong p = 0.003; IDI = 0.011; continuous NRI = 0.30). In the highest APACHE II quartile, the absolute mortality difference between minimal and very high Norton categories reached 23.2 percentage points. The Norton’s prognostic effect was approximately twice as large for post-ICU mortality (ΔAUC +0.011) as for overall in-hospital mortality (ΔAUC +0.006). Conclusions: The Norton scale at admission improves the prognostic capacity of APACHE II in critically ill patients, particularly for post-ICU mortality. Its widespread availability without additional patient-level data collection positions it as a pragmatic candidate for routine prognostic assessment and for guiding targeted nutritional screening.

Background/Objectives: Metastatic triple-negative breast cancer (mTNBC) carries a poor prognosis and limited treatment options. Sacituzumab govitecan (SG), an anti-Trop-2 antibody–drug conjugate, has shown activity in this setting, but a quantitative synthesis integrating randomized and real-world evidence—particularly in underrepresented subgroups—was lacking. We aimed to summarize the comparative benefit of SG, which derives from a single randomized trial, and to assess whether trial-level efficacy is consistent with the activity observed in routine practice. Methods: Following PRISMA 2020, we searched PubMed/MEDLINE and Web of Science (January 2017–April 2026) for trials and observational cohorts of SG monotherapy in mTNBC. Comparative effects were taken from randomized data; single-arm efficacy (objective response rate [ORR], clinical benefit rate [CBR], median progression-free [PFS], and overall survival [OS]) was pooled using random-effects models. Risk of bias was assessed with RoB 2 and ROBINS-I. The review was registered in the Open Science Framework. Results: Nine studies (1242 patients; 980 SG-treated) were included: one randomized trial (ASCENT), two single-arm trials, and six real-world cohorts. In ASCENT, SG improved PFS (hazard ratio [HR] 0.41, 95% CI 0.33–0.63) and OS (HR 0.51, 0.42–0.64). Pooled ORR was 31.1% (28.0–34.4), and CBR was 42.2% (37.7–46.8), with the median PFS being 4.8 months (4.4–5.3) and OS being 11.0 months (9.3–13.0); trial-derived and real-world estimates were concordant. The benefit persisted in older patients (HR 0.25) and Black women (HR 0.44) but not in those with brain metastases (HR 0.68, 0.38–1.23). Conclusions: SG shows clinically meaningful activity in mTNBC that is broadly consistent between controlled trials and routine practice. Comparative superiority over chemotherapy rests on a single randomized trial (ASCENT); the pooled single-arm estimates describe activity and its consistency rather than a comparative effect.

Background/Objectives: The nutrition transition in low- and middle-income countries has produced a double burden of malnutrition (coexistence of excess weight, undernutrition, and micronutrient deficiencies), with scarce evidence in schoolchildren from vulnerable peri-urban areas of Paraguay. The objective was to characterize, in a multidimensional way, the nutritional status of children and adolescents from Limpio and to explore its associations with anemia and clinical, dietary, and environmental variables, in particular, reported intestinal parasitosis. Methods: Cross-sectional observational study in 90 participants aged 6 to 16 years recruited by convenience at six community settings. Anthropometry, body composition, capillary hemoglobin, dietary patterns, and environment were assessed. Weight status was classified using the WHO 2007 references (z-scores), anemia was described using WHO thresholds, and central obesity was assessed using a waist-to-height ratio > 0.5. Non-parametric tests, Fisher’s exact test, Spearman correlations, and multivariable logistic regression were used. Results: Overweight or obesity affected 39.3% (obesity, 16.7%) and central obesity 22.4%, with no cases of thinness, coexisting with anemia (27.0%), stunting (8.2%), and reported intestinal parasitosis (24.1%). Anemia was more frequent in children with reported intestinal parasitosis (45% versus 20%; adjusted OR 5.44; 95% CI 1.44–20.51). Height-for-age was inversely associated with the number of siblings (ρ = −0.25). Conclusions: This population showed a double burden of malnutrition. The association between reported, non-laboratory-confirmed intestinal parasitosis and capillary-hemoglobin-defined anemia was exploratory and non-causal, given the cross-sectional design. Together with the high burden of anemia, these findings raise the hypothesis of a possible triple burden of malnutrition, which would require confirmation through stool parasitological testing and biomarkers of iron status, inflammation, and other micronutrients. These findings are compatible with integrated community strategies addressing dietary quality, sanitation, and access to safe water; decisions on deworming and micronutrient supplementation should be guided by local parasitological surveillance and biomarker-based assessment rather than by these data alone. Because the study used a convenience sample from a single peri-urban community during one fieldwork period, the findings should not be generalized beyond similar vulnerable settings without further confirmation.

Background/Objectives: Child undernutrition remains a critical public health issue in Nepal, especially in the rural district of Solukhumbu. This study aimed to assess the prevalence and clinical characteristics of undernutrition, dietary patterns, and related health indicators in school-aged children from the Shree Saraswoti Basic School in Phuleli. Methods: A descriptive, cross-sectional study was conducted between July and August 2022. Fifty-four children (51.8% boys; mean age 9.4 ± 2.1 years) were evaluated using anthropometry, clinical examination, hemoglobin measurement, and three-day 24 h dietary recall. Data were analyzed using descriptive and inferential statistics. Results: BMI z-scores indicated that 39% of children were at risk of acute undernutrition, and 2% were at risk of moderate acute undernutrition. After adjusting for altitude, 87% were classified as anemic. Diets were dominated by cereals and vegetables, with a very low intake of fruits and proteins and no dairy consumption. Dental caries affected 59% of participants. Girls presented slightly higher subcutaneous fat percentages; however, 14.8% of the children exceeded the recommended thresholds. A dietary assessment revealed poor eating habits, including excessive intake of simple carbohydrates and insufficient nutrient diversity. Although socioeconomic data were not directly collected, the findings reflect the typical context of the vulnerability of isolated mountain communities. Undernutrition indicators (BMI, clinical signs, anemia) were associated with poorer health outcomes. An unexpected moderate inverse correlation was found between BMI and both systolic (r = −0.601) and diastolic (r = −0.550) blood pressure. Conclusions: The findings reveal a high burden of undernutrition and anemia among children in Solukhumbu, linked to poor diet and structural vulnerability. Urgent, community-based interventions—including nutrition education, agricultural diversification, and improved healthcare access—are needed. Longitudinal monitoring is essential to track progress and design sustainable, multisectoral solutions.
