Lower lip reconstruction with the Karapandzic flap or the Colmenero flap: Description of results.

Background And Objective: Reconstruction of medium and large oncological defects of the lower lip must preserve the functionality and aesthetics of the area and is usually solved with local pedicled flaps, rarely compared between them. The aim of this study is to analyse our case series of lower lip reconstruction using the Karapandzic flap or the Colmenero flap, and to describe their techniques and results.

Materials And Methods: We performed a retrospective review of patients who underwent lower lip resection and reconstruction with the Colmenero flap or Karapandzic flap during the period 2015-2022 with a minimum follow-up time of more than one year.

The Impact of the COVID-19 Pandemic on Pregnancy, Birth Experiences, and Mental Health: Voices from Women in Puerto Rico.

Objectives: The specific aims of the project are: (1) Examine the impact of COVID-19 on pregnancy experiences and outcomes; (2) Examine the mental health impact of COVID-19 in pregnant women and mothers of children 12 months or younger; (3) Identify risk and protective factors among this population in Puerto Rico.

Methods: Participants were recruited from the Puerto Rico Team for Exploring Contamination Threats (PROTECT) Superfund Program, which is composed of pregnant women and mothers from the northern karst region of Puerto Rico. The research had a mixed methods approach with a quantitative survey (n = 184) and qualitative interviews (n = 10); data collection was done in virtual mode.

Evolution of ceftazidime-avibactam and cefiderocol resistance in ST131-H30R1- isolates with KPC-3 mutants and application of FTIR biotyping.

Ceftazidime-avibactam and cefiderocol represent two of the few alternatives for infections by KPC-producing Enterobacterales. We reported the emergence of resistance to both ceftazidime-avibactam and cefiderocol in a KPC-producing ST131- (KPC-ST131-) clinical isolate. Antimicrobial susceptibility testing, Fourier-transform infrared (FTIR) spectroscopy, whole-genome sequencing, and cloning experiments were performed.

Calorie Restriction and Time-Restricted Feeding: Effective Interventions in Overweight or Obese Patients Undergoing Radiotherapy Treatment with Curative Intent for Cancer.

This study assesses the feasibility of calorie restriction (CR) and time-restricted feeding (TRF) in overweight and obese cancer patients who realized little to no physical activity undergoing curative radiotherapy, structured as a prospective, interventional, non-randomized open-label clinical trial. Of the 27 participants initially enrolled, 21 patients with breast cancer were selected for analysis. The participants self-selected into two dietary interventions: TRF, comprising a sugar and saturated fat-free diet calibrated to individual energy needs consumed within an 8 h eating window followed by a 16 h fast, or CR, involving a 25% reduction in total caloric intake from energy expenditure distributed across 4 meals and 1 snack with 55% carbohydrates, 15% protein, and 30% fats, excluding sugars and saturated fats.

Results of surgical treatment of lymph node metastases in patients with cutaneous squamous cell carcinoma of the head and neck.

Introduction: Out of all cutaneous squamous cell carcinomas originating in the head and neck (HNCSCC), 2-4% are associated with parotid or cervical lymph node metastasis. The aim of this study is to analyse the prognostic factors of patients with HNCSCC with lymph node involvement treated surgically. Additionally, we aim to compare the prognostic capacity of the classification of these patients according to the 8th edition of the TNM, and an alternative classification proposed by O'Brien et al.

Reduction in Preterm Preeclampsia after Contingent First-Trimester Screening and Aspirin Prophylaxis in a Routine Care Setting.

Objectives: Several multivariate algorithms for preeclampsia (PE) screening in the first trimester have been developed over the past few years. These models include maternal factors, mean arterial pressure (MAP), uterine artery Doppler (UtA-PI), and biochemical markers (pregnancy-associated plasma protein-A (PAPP-A) or placental growth factor (PlGF)). Treatment with low-dose aspirin (LDA) has shown a reduction in the incidence of preterm PE in women with a high-risk assessment in the first trimester.

Translational demand is not a major source of plasmid-associated fitness costs.

Plasmids are key drivers of bacterial evolution because they are crucial agents for the horizontal transfer of adaptive traits, such as antibiotic resistance. Most plasmids entail a metabolic burden that reduces the fitness of their host if there is no selection for plasmid-encoded genes. It has been hypothesized that the translational demand imposed by plasmid-encoded genes is a major mechanism driving the fitness cost of plasmids.

Gestational Hormone Concentrations Are Associated With Timing of Delivery in a Fetal Sex-Dependent Manner.

Background: Early delivery remains a significant public health problem that has long-lasting impacts on mother and child. Understanding biological mechanisms underlying timing of labor, including endocrine disruption, can inform prevention efforts.

Methods: Gestational hormones were measured among 976 women in PROTECT, a longitudinal birth cohort in Puerto Rico.

Participation in genetic research among Latinx populations by Latin America birth-residency concordance: a global study.

Latinx populations are underrepresented in DNA-based research, and risk not benefiting from research if underrepresentation continues. Latinx populations are heterogenous; reflect complex social, migration, and colonial histories; and form strong global diasporas. We conducted a global study using a survey tool (Amazon's Mechanical Turk portal) to ascertain willingness to participate in genetic research by Latin America birth-residency concordance.

Preterm birth and PM in Puerto Rico: evidence from the PROTECT birth cohort.

Background: Preterm birth (PTB, birth before 37 weeks of gestation) has been associated with adverse health outcomes across the lifespan. Evidence on the association between PTB and prenatal exposure to air pollutants is inconsistent, and is especially lacking for ethnic/racial minority populations.

Methods: We obtained data on maternal characteristics and behaviors and PTB and other birth outcomes for women participating in the Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) cohort, who lived in municipalities located along the North Coast of Puerto Rico.

High parathyroid hormone predicts exacerbations in COPD patients with hypovitaminosis D.

Background: Hypovitaminosis D has been linked to deterioration in clinical parameters and lung function in COPD. As a response to low levels of vitamin D serum Parathyroid Hormone (iPTH) is increased in some, but not all, patients. The aim of this study was to determine whether COPD patients with elevated PTH levels are at higher risk of COPD exacerbations and hospitalizations.

Pervasive transmission of a carbapenem resistance plasmid in the gut microbiota of hospitalized patients.

Infections caused by carbapenemase-producing enterobacteria (CPE) are a major concern in clinical settings worldwide. Two fundamentally different processes shape the epidemiology of CPE in hospitals: the dissemination of CPE clones from patient to patient (between-patient transfer), and the transfer of carbapenemase-encoding plasmids between enterobacteria in the gut microbiota of individual patients (within-patient transfer). The relative contribution of each process to the overall dissemination of carbapenem resistance in hospitals remains poorly understood.

Correction to: International prospective observational cohort study of Zika in infants and pregnancy (ZIP study): study protocol.

Following publication of the original article [1], the author mentioned that two additional NIH staff were involved in the development of the protocol who did not receive recognition in the Acknowledgments section in their published article.

International prospective observational cohort study of Zika in infants and pregnancy (ZIP study): study protocol.

Background: Until recently, Zika virus (ZIKV) infections were considered mild and self-limiting. Since 2015, they have been associated with an increase in microcephaly and other birth defects in newborns. While this association has been observed in case reports and epidemiological studies, the nature and extent of the relationship between ZIKV and adverse pregnancy and pediatric health outcomes is not well understood.

Turbocharged bilateral pedicled DIEP flap for reconstruction of thigh defect without recipient vessels: A case report.

Reconstruction of thigh defects is usually straightforward, but in cases of poor soft tissue quality, free flap reconstruction is not possible due to the absence of recipient vessels. The turbocharge technique may increase the viable, vascularized area of a flap. In this report we present a case of the use of a turbocharged bilateral pedicled DIEP flap for reconstruction of thigh defect without recipient vessels.

Community Engagement and Research Translation in Puerto Rico's Northern Karst Region: The PROTECT Superfund Research Program.

We describe here the social science-environmental health collaboration in PROTECT, the Puerto Rico Testsite for Exploring Contamination Threats, which is one of eighteen Superfund Research Program centers funded by the National Institute of Environmental Health Sciences. This collaboration has multiple facets: (1) create a holistic, unified research program that addresses the complexity of environmental contamination, (2) offer research participants an engaged and respectful interaction with the research team, (3) provide cross-training, in which the team's social scientists learn environmental health and the environmental health scientists learn social science, and (4) provide training for graduate students and post-docs in multiple disciplines in this burgeoning form of collaboration.

Reconstruction of oral cavity defects with FAMM (facial artery musculomucosal) flaps. Our experience.

Introduction And Objectives: The facial artery musculomucosal (FAMM) flap is a good option for covering small and medium-sized defects in the oral cavity because of its similar tissue characteristics and easy implementation.

Methods: We reviewed our results using this flap between 2006 and 2014. A total of 20 patients were included and 25 FAMM flaps were performed, 16 right (64%) and 9 left (36%) flaps.

Increasing opportunistic oral cancer screening examinations: findings from focus groups with general dentists in Puerto Rico.

This study aims to identify educational and training modalities that dentists in Puerto Rico (PR) believe will increase the quality and quantity of opportunistic oral cancer screening examinations (OCS) in dental offices on the island. The study was conducted in three phases: a systematic search of relevant literature, an expert review and consensus panel, and focus groups (FG) involving PR general dentists. To increase OCS by dentists in PR, the FG participants proposed a small group, hands-on OCS training, an integrated oral cancer course, and readily available videos, photographs, and computer simulations to further demonstrate OCS performance and facilitate differential diagnosis.

Acoustic radiation force impulse elastography and contrast-enhanced sonography of sinusoidal obstructive syndrome (Veno-occlusive Disease): preliminary results.

We report quantitative liver acoustic radiation force impulse (ARFI) elastographic findings in 2 cases of sinusoidal obstructive syndrome and liver contrast-enhanced sonographic features in one of these cases. To our knowledge, findings in this condition from these techniques have not been reported previously. Acoustic radiation force impulse elastography showed median high shear wave velocities (case 1, 2.
