Background: s/Aims: Three-dimensional (3D) modeling is increasingly used in hepatobiliary surgery to enhance anatomical understanding and operative planning. However, its impact on oncologic outcomes remains uncertain. This study evaluated whether preoperative 3D liver models influence resection margin status and survival after hepatectomy for malignant disease. Methods: In this retrospective case-control study, 59 patients undergoing hepatic resection for malignancy between May 2018 and May 2023 were included. Patients were managed either with patient-specific 3D models (n = 31) or conventional imaging (n = 28). Predictors of R0 resection were analyzed using logistic regression, and overall survival (OS) and disease-free survival (DFS) were assessed using Cox proportional hazards models. Results: R0 resection was achieved in 79.7% of patients, with no significant difference between groups (77.4% vs. 82.1%; p = 0.865). Bilobar tumor distribution (adjusted odds ratio [OR] 0.05, 95% confidence interval [CI] 0.00–0.76; p = 0.039) and a higher albumin-bilirubin score (adjusted OR 0.06, 95% CI 0.00–0.46; p = 0.029) were independently associated with lower odds of achieving R0 resection.In multivariable analysis, the use of 3D models was independently linked to improved 2-year DFS (adjusted hazard ratio 0.47, 95% CI 0.24–0.92; p = 0.028). Tumor type affected recurrence rates, with hepatocellular carcinoma and other tumors showing a lower risk of recurrence compared to colorectal liver metastases. No significant differences in OS were found. Conclusions Preoperative 3D modeling was not associated with higher R0 resection rates but was independently associated with improved 2-year DFS. Given the retrospective design and potential residual confounding, these findings should be interpreted cautiously and considered hypothesis-generating pending prospective validation.

Background: Antibiotic Stewardship Programs (ASP) have improved empirical and directed antibiotic treatment in Gram-negative Bacilli (GNB) bloodstream infections. A decrease in mortality, readmission, and length of hospitalization has been reported. Materials and Methods: A pre–post-quasi-experimental study was conducted between November and April 2015–2016 (pre-intervention period), 2016–2017, 2017–2018, and 2018–2019 (post-intervention periods), to analyse the impact of ASP on empirical, directed, and entire treatment optimization, as well as mortality, readmission, and length of hospitalization, in hospitalized patients with Gram-negative bacilli (GNB) bloodstream infections. Results: One hundred seventy-four patients were included (41 in the pre-intervention group, 38 in the first-year post-intervention group, 50 in the second-year post-intervention group, and 45 in the third-year post-intervention group). There was a significant improvement in directed treatment optimization (43.9% in the pre-intervention group, 68.4% in the first-year post-intervention group, 74% in the second-year post-intervention group, and 88.9% in the third-year post-intervention group, P <0.001), as well as in entire treatment optimization (19.5%, 34.2%, 40.0%, and 46.7%, respectively, P=0.013), with increased optimal directed (adjusted odds ratio [aOR], 3.71; 95% confidence interval [CI], 1.60–8.58) and entire treatment (aOR, 3.31; 95% CI, 1.27–8.58). Although a tendency toward improvement was observed in empirical treatment after ASP implementation, it did not reach statistical significance (41.5% vs. 57.9%, P=0.065). No changes in mortality, readmission, or length of hospitalization were detected. Conclusion ASP implementation improved both directed and entire treatment optimization in patients with GNB bloodstream infections over time. Nevertheless, no improvement was found in clinical outcomes such as mortality, readmission, or length of hospitalization.

BACKGROUND: The prevalence of heart failure (HF) increases with age, and it is one of the leading causes of hospitalization and death in older patients. However, there are little data on in-hospital mortality in patients with HF ≥ 75 years in Spain. METHODS: A retrospective analysis of the Spanish Minimum Basic Data Set was performed, including all HF episodes discharged from public hospitals in Spain between 2016 and 2019. Coding was performed using the International Classification of Diseases, 10^th Revision. Patients ≥ 75 years with HF as the principal diagnosis were selected. We calculated: (1) the crude in-hospital mortality rate and its distribution according to age and sex; (2) the risk-standardized in-hospital mortality ratio; and (3) the association between in-hospital mortality and the availability of an intensive cardiac care unit (ICCU) in the hospital. RESULTS: We included 354,792 HF episodes of patients over 75 years. The mean age was 85.2 ± 5.5 years, and 59.2% of patients were women. The most frequent comorbidities were renal failure (46.1%), diabetes mellitus (35.5%), valvular disease (33.9%), cardiorespiratory failure (29.8%), and hypertension (26.9%). In-hospital mortality was 12.7%, and increased with age [odds ratio (OR) = 1.07, 95% CI: 1.07-1.07, P < 0.001] and was lower in women (OR = 0.96, 95% CI: 0.92-0.97, P < 0.001). The main predictors of mortality were the presence of cardiogenic shock (OR = 19.5, 95% CI: 16.8-22.7, P < 0.001), stroke (OR = 3.5, 95% CI: 3.0-4.0, P < 0.001) and advanced cancer (OR = 2.6, 95% CI: 2.5-2.8, P < 0.001). In hospitals with ICCU, the in-hospital risk-adjusted mortality tended to be lower (OR = 0.85, 95% CI: 0.72-1.00, P = 0.053). CONCLUSIONS In-hospital mortality in patients with HF ≥ 75 years between 2016 and 2019 was 12.7%, higher in males and elderly patients. The main predictors of mortality were cardiogenic shock, stroke, and advanced cancer. There was a trend toward lower mortality in centers with an ICCU.

Ameloblasts are specialized cells derived from the dental epithelium that produce enamel, a hierarchically structured tissue comprised of highly elongated hydroxylapatite (OHAp) crystallites. The unique function of the epithelial cells synthesizing crystallites and assembling them in a mechanically robust structure is not fully elucidated yet, partly due to limitations with in vitro experimental models. Herein, we demonstrate the ability to generate mineralizing dental epithelial organoids (DEOs) from adult dental epithelial stem cells (aDESCs) isolated from mouse incisor tissues. DEOs expressed ameloblast markers, could be maintained for more than five months (11 passages) in vitro in media containing modulators of Wnt, Egf, Bmp, Fgf and Notch signaling pathways, and were amenable to cryostorage. When transplanted underneath murine kidney capsules, organoids produced OHAp crystallites similar in composition, size, and shape to mineralized dental tissues, including some enamel-like elongated crystals. DEOs are thus a powerful in vitro model to study mineralization process by dental epithelium, which can pave the way to understanding amelogenesis and developing regenerative therapy of enamel.

Background: In order to financially sustain the participation of the private sector in the UHC, there is a need to find reasonable balance of accountability in the costing of health services. The costing must be based on actual resources used from the perspective of the private health service provider. Objective: The objective of this paper was to determine the cost of primary care services from the framework of the UHC reform in the private sector. Method: This is a multi-method approach to cost-identification in establishing and providing primary care health service in the UHC. The approaches used by the authors included review of published literature, laws and policies from DOH and other regulatory agencies. From this review, they develop the minimum facility requirement for basic primary care facility and primary care facility with ancillary services. They used the actual expenditures of existing primary care clinics, 2021 quotations from equipment and supplies companies, published construction rates and consensus approach to establish the cost. Based on 2021 value of Philippine Peso, they estimated the cost of constructing and operating a primary care facility. Results: The total estimated cost of building a primary health care facility based on the DOH licensing standard was estimated to be around PhP2,490,000. The cost of furniture and equipment as required in the DOH AO was PhP474,685. Thus, the total cost of the construction and equipment for a basic primary care facility setup is PhP2,964,685. We estimated the annual operating cost with the building estimated to depreciate in 20 years and the furniture and equipment in 5 years, the annualized cost for the building is PhP124,500 and for the furniture and equipment PhP94,937. The total annual salary of the staff based on government standards was PhP2,381,962. The maintenance, operating and overhead expenses (MOOE) which included water and electricity, repair and maintenance, waste disposal, supplies and other fees was PhP451,190. The total annual operating cost of a basic primary care facility is PhP3,052,590. This facility can provide basic services such as outpatient consultation and minor surgeries. Using the same approach for the basic facility, the total annual operating cost of a basic primary care facility with ancillary service is PhP11,023,670. This facility can provide outpatient consultation, minor surgeries and primary care services such as health education and preventive care plus the ancillary services like pharmacy, clinical laboratory and x-ray. For patients with diabetes, the total annual cost is PhP8,986. The significant cost driver is the clinical assessment and non-pharmacologic intervention. The researchers found the same cost pattern for the annual cost care of patients with hypertension but with a slightly higher annual total with PhP9,963. Their sensitivity analysis based on inflation, construction, equipment and operating expense may increase these cost estimates by 20% in the next 5 years. Conclusion Based on their findings, the current per capita support from PHIC Konsulta package is not adequate in the private sector both for wellness and care of patients with chronic condition. PHIC needs to consider adjusting per capita rates and consider case rate payment as it is currently doing for hospital care. Without this proposed adjustment, only those patients in the higher socioeconomic status will be capable of consulting the private sector. This scenario defeats the equity issue that is a primary concern in the UHC.

Background: Sunburn is the main avoidable cause of skin cancer. Beach lifeguards spend many hours exposed to the effects of solar radiation during their work day, precisely at times of the year when levels of solar irradiation are highest. The aim of this study is to quantify the risk to beach lifeguards of sun exposure. Methods: A descriptive cross-sectional study was carried out in the Western Costa del Sol, southern Spain, during the summer of 2018. The research subjects were recruited during a skin cancer prevention course for beach lifeguards. All participants were invited to complete a questionnaire on their habits, attitudes, and knowledge related to sun exposure. In addition, ten were specially monitored using personal dosimeters for three consecutive days, and the results were recorded in a photoprotection diary. A descriptive analysis (mean and standard deviation for the quantitative variables) was performed, and inter-group differences were evaluated using the Mann–Whitney U test. Results: Two hundred fifteen lifeguards completed the questionnaire, and 109 met the criteria for inclusion in this analysis. The mean age was 23.8 years (SD: 5.1), 78.0% were male, 71.5% were phototype III or IV (Fitzpatrick's phototype), and 77.1% had experienced at least one painful sunburn during the previous summer. The mean daily personal ultraviolet exposure per day, the minimal erythema dose, and the standard erythema dose, in J/m2, were 634.7 [standard deviation (SD): 356.2], 2.5 (SD: 1.4) and 6.35 (SD: 3.6), respectively. Conclusion Beach lifeguards receive very high doses of solar radiation during the work day and experience correspondingly high rates of sunburn. Intervention strategies to modify their sun exposure behavior and working environment are necessary to reduce the risk of skin cancer for these workers and to promote early diagnosis of the disease.
