Objective: The current study aimed to explore changes in health-related behaviors and social practices in Hispanic cancer patients during a government-mandated lockdown and their relationship to sociodemographic and clinical characteristics.

Methods: Secondary analyses were conducted on data gathered by a longitudinal cohort study to describe the unmet needs of Hispanic cancer patients living in Puerto Rico exposed to Hurricane Maria in 2017, earthquakes in 2020, and COVID-19. However, our study solely focuses on the data from the COVID-19 pandemic period.

Results: Most participants were women (n = 72) with breast cancer (81.2%). Participants exhibited changes in religious practices (60%), physical activity (58.4%), and sedentary behavior (50%); 31.4% experienced changes in eating habits and sleeping patterns. Responses to the study questionnaire involved staying connected with family (85.5%) through phone calls (78.2%); 69.9% of the participants reported observing shifts in the family dynamics. A strong majority endorsed the government-imposed isolation measures (95.6%). Patients not undergoing treatment were likelier (r = -0.324; P = .010) to support the measures. Finally, younger patients experienced more work-related changes (r = -0.288; P = .017) and were less inclined (r = -0.293; P = .011) to find the isolation measures appropriate.

Conclusion: This paper describes the lockdown related changes in health and social behaviors sustained by cancer patients, changes which could potentially impact their overall health and health-related quality of life. Our results fill an existing gap in our findings and contribute to understanding the experiences of cancer patients (in particular, Hispanic patients) during the COVID-19 pandemic.

A 6-year-old Hispanic patient presented with a 1-month history of pruritic patches on her scalp, characterized by hair loss, black dots, and dandruff-like scales. The patient was seen by her primary care physician, who prescribed ketoconazole 2% shampoo. This provided little relief for her symptoms, which prompted her admission to nearby hospital, where fluconazole was administered intravenously and mometasone lotion applied. The patient was discharged and instructed to use the ketoconazole shampoo and mometasone lotion. The previously prescribed medications failed to improve her now enlarged, inflamed, scaly, pustule-speckled lesions. Given her condition, she was admitted to the University Pediatric Hospital in San Juan, where the Dermatology Department was consulted. Cultures were taken from the lesions, revealing the presence of Trichophyton tonsurans, which led to the diagnosis of tinea capitis (ringworm of the scalp) with kerion formation. In addition, multiple nits and adult lice characteristic of Pediculus humanus capitis were observed. A 6-week course of griseofulvin, a 1-week course of permethrin solution, and a 5-day course of oral prednisolone were started, effectively cleared the patient's inflammation and fungal infection. This case highlights how there exist areas of improvement in terms of interprofessional communication between physicians, as well a need to increase awareness of the proper treatment for this common pediatric skin condition. We postulate that in doing so, similar cases could be spared the unfortunate results of untreated tinea capitis, that is, kerion formation and the possible scarring this lesion can produce.

Objective: Direct-acting antiviral (DAA) drugs have resulted in high rates of virological cure in chronic hepatitis C (CHC)-infected patients. We used noninvasive tests to assess fibrosis in subjects who had been cured with DAA.

Methods: Retrospective data collection (2014-2019) from the medical record of CHC patients at the hepatology clinic was performed. Subjects co-infected with HIV and hepatitis B, post-liver transplant, and lost to follow-up were excluded. We evaluated fibrosis at baseline and 1 year after completing therapy using vibration-controlled transient elastography (VCTE), fibrosis-4 (FIB-4), and aspartate aminotransferase-toplatelet ratio index (APRI) scores.

Results: With 210 medical records reviewed, 41 were included. The mean age was 62.8 years; 61% were men. Significant fibrosis regression was observed 1-year post-treatment using 3 noninvasive methods: VCTE, APRI, and FIB-4 score. Prior to treatment, 46% of the patients had advanced fibrosis compared to 25% 1 year after treatment. The VCTE scores of 4 subjects (with body mass indices [BMIs] > 30) indicated a worsening of fibrosis. We did not find a statistically significant association between BMI and VCTE, FIB-4, or APRI score.

Conclusion: In most CHC patients, DAA therapy leads to liver fibrosis regression. Obesity may play an important role in the worsening of hepatic fibrosis or the absence of fibrosis regression.

Mevalonate kinase deficiency is a rare autosomal recessive disease caused by mutations in the mevalonate kinase gene (MVK). Depending on the mutations, a patient with this deficiency can exhibit any one of a spectrum of rare autoinflammatory diseases, such as hypergammaglobulinemia D (hyper-IgD) with periodic fever syndrome and mevalonic aciduria. To date, approximately 300 cases with mutations in the MVK gene have been reported worldwide. Herein, we present a 3-year-old female from Puerto Rico with a history of fever, arthralgia, and skin lesions since her first month of age and who, upon genetic workup, was confirmed to have compound heterozygous mutations in the MVK gene. Given her medical history and the results of her genetic testing, she was diagnosed with hyper-IgD with periodic fever syndrome. She will be treated with canakinumab, an interleukin-1ß antagonist, after receiving the varicella and measles-mumps-rubella (MMR) vaccines.

Objective: Vitiligo is a dermatological autoimmune condition characterized by areas of progressive skin depigmentation. Vitiligo lesions are cosmetically disfiguring and associated with significant psychological conditions such as depression and anxiety and comorbidities such as thyroid disease and diabetes. All races, ethnicities, ages, and regions of the world are impacted by vitiligo, with a global prevalence of about 0.5-2%. Currently, there is no published information available on the prevalence of vitiligo in Puerto Rico. Our study's aim was to estimate the prevalence of vitiligo among patients attending the specialized clinic of dermatology at UPR School of Medicine in Puerto Rico and describe the distribution of cases by age and sex.

Methods: We performed a descriptive study to evaluate the patients attending the University of Puerto Rico School of Medicine Clinics from January 2017 to May 2022. Using ICD-10 code L80 and medical records, we identified 581 patients with vitiligo and their respective demographic data distributed by sex and age.

Results: Of the 581 vitiligo patients, 350 (60.2%) were women, and 231 (39.8%) were men. The median age in the vitiligo population was 33.5 years. Out of the studied sample, 30.2% were under the age of 18. Overall, there was an estimated prevalence of 5.2%.

Conclusion: We report a vitiligo prevalence of 5.2% in a specialized clinic in Puerto Rico, suggesting further studies are necessary to discover possible underlying factors contributing to this increased prevalence.

Objective: To explore the association between hygiene knowledge and habits and gingivitis in Puerto Rican school children.

Methods: Questionnaires on oral health knowledge and hygiene habits were provided to almost half of the 12-year-olds who participated in an island-wide cross-sectional oral health study. The evaluations included gingival examinations in 2 quadrants. Odds ratios (ORs) (with 95% CIs) were computed using logistic regression models and oral health-related knowledge and hygiene habits to gingivitis.

Results: Of the 823 participants who completed the questionnaire 53.43% were female, and 81% had gingivitis. Most reported having received instructions on brushing (98%), flossing (89.5%), and using mouthwash (90%). The majority (75%) rated their gums as healthy, and 44.68% agreed that oral health affects general health. Nearly half (44%) reported brushing their teeth at least 2 times a day, and 80.25%, flossing daily. In multivariate analysis, not having been instructed on how to brush was related to greater odds of having gingivitis (OR: 7.32; 95% CI: 1.5-35.67). Flossing more than once a day was associated with half the odds of gingivitis (OR: 0.50; 95% CI: 0.29-0.88).

Conclusion: The children had knowledge of oral hygiene methods but were mostly unaware that gingival health could affect systemic health. Fewer than half reported brushing 2 or more times a day. Not having been instructed on how to brush was associated with higher odds of gingivitis.

Objective: Monitoring the susceptibility patterns of Neisseria gonorrhoeae is essential for the continuing compliance with current treatment recommendations. Puerto Rico conducts susceptibility tests on N. gonorrhoeae; however, trends on antimicrobial resistance in the island have not been reported since the mid 80's.

Methods: We performed a secondary analysis of a national data repository on the antimicrobial susceptibility of N. gonorrhoeae isolates between 2012 and 2017; a period of time when the CDC recommended a single dose of ceftriaxone and azithromycin for the treatment of uncomplicated gonorrhea. Data on susceptibility to eight antibiotics using the standard disk diffusion method was obtained for 30.0% (84/276) of the samples collected from the Sexually Transmitted Disease clinics in Puerto Rico. We also performed patient demographic analyses linked to resistance.

Results: Rates of resistance to ceftriaxone and azithromycin were 0% and 4.0% (2/50), respectively. The percentage of isolates resistant to antimicrobials no longer recommended in Puerto Rico, such as tetracycline, ciprofloxacin, and penicillin, was 86.0% (43/50), 76.0% (38/50), and 38.0% (19/50), respectively. Prevalence of resistant N. gonorrhoeae was higher among men who have sex with men, MSM (79%, 37/47).

Discussion: Lack of resistance to ceftriaxone and slow emergence of azithromycin resistance was identified from 2012-2017. It is imperative to continue the surveillance for emerging patterns of resistance, especially for ceftriaxone, as it is part of the current treatment guidelines. Therefore, protocols for culture based surveillance, including sample transport and processing, should be strengthened to ensure quality assured epidemiology of gonococcal resistance in Puerto Rico.

Currently, there is limited data available comparing Primary Mediastinal Large B-cell Lymphoma (PMBL) and mediastinal Hodgkin disease, nodular sclerosis type (HDNS). This is a retrospective cohort study that compares the clinical features, histology through immunohistochemistry (IHC) and treatment outcomes of 19 cases of PMBL and 39 cases of HDNS diagnosed over 13 years at a single institution in San Juan, PR. Superior Vena Cava syndrome (SVCS) and elevated Lactate Dehydrogenase (LDH) levels were more frequently seen in the PMBL cohort. At the median follow-up visit, of 74 months, no significant difference was seen in overall survival or progression free survival between PMBL and HDNS. Almost all of the relapses in the PMBL group occurred within 12 months of diagnosis. Our data suggests that PMBL and HDNS differ in their clinical presentation and have a favorable prognosis.

Objective: Increased mupirocin use leads to mupirocin resistance and is associated with persistence of methicillin-resistant Staphylococcus aureus (MRSA) carriers, prolonged hospitalization, and significant economic burdens for health systems. The study aimed to investigate the antimicrobial activity of compounds of Salvia rosmarinus L. ("rosemary", formerly Rosmarinus officinalis), alone or in combination with mupirocin, against multidrug resistant MRSA using isolates obtained from pediatric patients.

Methods: The in vitro antibacterial activity of the monoterpene α-pinene (α-Pi), a rosemary essential oil constituent, alone and in combination with mupirocin, was evaluated by determining the minimum inhibitory concentrations and minimum bactericidal concentrations (MBCs) and the fractional inhibitory concentration indices (FICIs) and fractional bactericidal concentration indices against multidrug-resistant clinical MRSA strains. The in vivo efficacy of α-Pi, alone and in combination with mupirocin, to eradicate MRSA infection was determined using an optimized mouse model of MRSA-infected wounds. Mouse skin samples (obtained via biopsy) were assessed for toxicity, and rabbit skin samples for irritation.

Results: Both in vitro and in vivo, α-Pi was active against MRSA strains and acted synergistically with mupirocin against MRSA strains. Mupirocin-monoterpene combinations exhibited FICI values of 0.2 to 0.4, reducing the MBC of topical mupirocin 33-fold. A topical formulation containing α-Pi and mupirocin enhanced the efficacy of mupirocin in an in vivo MRSA-infected mouse skin model without significantly harming the skin of mice and rabbits.

Conclusions: A topical formulation combining mupirocin and α-Pi may aid in the development of innovative agents for treating MRSA infections.

Objective: The Family Adaptability and Cohesion Evaluation Scale III (FACES III) is a self-report instrument that enables the assessment of the dimensions of adaptability and cohesion within a family, establishing whether or not that family is functional and classifying it according to categories within those dimensions. The objective of this research was to determine the psychometric properties of this instrument using a sample of dental students from 5 Latin American countries.

Materials and methods: The FACES III was administered to a sample of 2888 university dental students from Colombia (35.3%), Chile (34.6%), the Dominican Republic (19%), Argentina (6%), and El Salvador (5.1%). Confirmatory factor analysis was used to examine the factorial structure of the scale, comparing 3 models proposed in the Latin American literature, establishing a multigroup analysis to examine invariance among countries.

Results: The results revealed a structure composed of 2 dimensions: cohesion and adaptability. These dimensions showed adequate structure and internal consistency. The invariance of the measurement model in the participating countries was confirmed.

Conclusion: In general, this study offers evidence of the adequacy of the psychometric properties of FACES III in Colombian, Chilean, Dominican, Argentine, and Salvadoran dental students.
