We aimed to improve the available information on morphology and stage for cutaneous melanoma in the population-based cancer registry of the Bucaramanga Metropolitan Area in Colombia. The incidence and survival rates and the distribution of melanoma patients by age, gender, anatomical subsite, and histological subtype were calculated. All 113 melanoma patients (median age 61) were followed up (median time 7.4 years). This exercise (filling in missing information in the registry by manual search of patient clinical record and other available information) yielded more identified invasive melanomas and cases with complete information on anatomical localization and stage. Age-standardized incidence and mortality rates were 1.86 and 1.08, being slightly higher for males. Most melanomas were localized on the lower limbs, followed by the trunk. For 35% of all melanomas, the morphological subtype remained unknown. Most of the remaining melanomas were nodular and acral lentiginous melanomas. Overall global and relative 5-year survival was 61.6% and 71.3%, respectively, with poorer survival for males than females. Melanomas on the head and neck and unspecified anatomical sites had the worst survival. Patients without stage information in their medical files had excellent survival, unlike patients for whom medical files were no longer available. This study shows the possibility of improving data availability and the importance of good quality population-based data.

Background: There is scarce information on the burden of invasive pneumococcal disease (IPD) among adults in low-and middle-income countries. This study aimed to describe the clinical outcomes and microbiological characteristics associated with IPD in adults and subgroups aged 18-59 years and >= 60 years in Colombia Methods: A retrospective chart review study was conducted in five institutions of Bogot & aacute; from January 2011 to December 2017. Analyses were carried out for overall population and stratified by age group (18-59; >= 60 years) Results: There were 169 IPD cases; median age was 58 years, 51.5% were male, and 80.5% had at least one comorbidity. Bacteremic pneumonia was the most common presentation (63.9%). The median length of hospital stay was 12 days with high healthcare resource utilization (HCRU): 58.6% required ICU and 53.3% inotropic support. Overall case-fatality rate (CFR) was 41.4%. Clinical outcomes were worse in patients >= 60 years old with significantly higher CFR and HCRU (ICU admission, mechanical ventilation, and inotropic support) compared to those aged 18-59 years. The most frequent serotypes were 3, 6 A/C, 14, and 19A. The sensitivity to penicillin in meningitis and non-meningitis isolates were 75% and 89.1% respectively Conclusions: IPD was associated with a substantial burden in adults and worse clinical outcomes and HCRU in older adults in Colombia. Surveillance data combined with clinical outcomes have the potential to inform age-based pneumococcal vaccination policies.

Objective: To determine the prevalence of comorbidities among adults living with HIV from two healthcare centers in Colombia, and to identify factors associated with comorbidity-free years. Methods: Observational, retrospective medical chart review study. Summary statistics for demographic and clinical characteristics were developed and relationship between comorbidity-free years were analyzed through Kaplan-Meier analysis and Cox regression. Results: 669 clinical charts were included, 71.7% were male and 16.1% were 50 years or older, 69.96% had at least one comorbidity. The most frequent comorbidities were dislipidemia(15.06%), hypertension(5.67%), risk factors were tobacco use(15.33%), alcohol intake(24.36%) and drugs abuse (14.66%). Discussion: These findings are consistent with previous reports showing the underlying processes of patients, producing multiple comorbidities. Conclusions: Significant proportion of patients have comorbidities that may increase risk of other complications or reduced comorbidity-free years. Poly-pharmacy among HIV+ adults need to be addressed to ensure adherence and minimize drug-drug interactions.

Introduction: Genital warts are benign lesions caused by sexual transmission of human papillomavirus types 6 and 11, with significant impact on healthcare resource use and patients’ quality of life. Objective: To describe the epidemiology of genital warts in adults visiting a physician office for any reason, physician practice patterns, and healthcare resource use and costs in Colombia. Methods: Participants were a convenience sample of 53 physicians in 5 specialties: primary care (15), gynecology (24), urology (12), proctology (1), and dermatology (1). Physicians completed a survey and daily log of all patients 18-60 years old seen over 10 days in their practices in 2016-2017. The physician survey recorded genital warts consultation and management patterns. The daily log recorded patient demographic information and genital warts diagnosis. Results: Among 6,393 patients logged by physicians, the genital warts prevalence was 2.03% (95%CI 1.69–2.38) and incidence 1.30% (95%CI 1.02–1.58). Primary care physicians referred most of their genital warts cases for treatment (female: mean 63.3%, SD=44.8; male: mean 58.3%, SD=43.8). Treatment of non-resistant episodes (<6-month duration) lasted an average of 37.4 days (SD=29.4) and required an average of 4.0 (SD=1.9) office visits for females and 3.0 (SD=1.7) for males. The overall mean cost of an episode of care was USD558.13 (SD=507.30). Conclusion: Genital warts cases reported by most participant physicians were mainly direct-consult, but patients were typically treated by specialists. Much of the genital warts health care utilization and costs reported could be prevented by immunization with the quadrivalent or nonavalent HPV vaccine.

Objective: In Mexico, head and neck cancers pose a significant health burden. GLOBOCAN reported approximately 3183 new cases and 1636 deaths in 2020. Despite being the sixth leading cause of cancer incidence and mortality worldwide, data on epidemiology and treatment patterns in Mexico remain limited. This study aimed to characterize the profile, clinical features, and management of patients with Stage III–IVB head and neck squamous cell carcinoma (HNSCC) in a real-world setting. Methods: We retrospectively analyzed a database of 187 patients with Stage III, IVA, or IVB HNSCC treated at the University Hospital Dr. José Eleuterio González. Demographics, disease characteristics, and treatment patterns were summarized as frequencies and percentages. Exploratory endpoints included clinical outcomes and recurrence types. Results: The cohort was 82.9% male (n = 155). The most frequent tumor sites were the oral cavity (36.9%) and larynx (36.9%), with 55% (n = 103) diagnosed at stage IVA. Of 75 cases tested for p16, 35.3% (n = 36) were positive. The median time from symptom onset to diagnosis was 166.5 days (95% CI: 123.4–197.8) and from diagnosis to treatment 42 days (95% CI: 31.6–50.4). Initial treatments included surgery (36.4%), chemoradiotherapy (24.6%), induction chemotherapy (19.8%), supportive care (11.2%), and radiotherapy (8%). Locoregional control was achieved in 42.8% of patients, with an overall recurrence rate of 2.8%. Conclusions: This study provides real-world insights into the epidemiology and management of locally advanced HNSCC in Mexico, outlining the patient journey from initial symptoms to treatment and underscoring the need for more individualized therapeutic strategies based on molecular profiling and clinical characteristics.
