Background: Gastric lymphoma of mucosa-associated lymphoid tissue (MALT) is related to Helicobacter pylori infection and may depend on this infection for growth.Objective: To determine the response of gastric MALT lymphoma to antibiotic treatment.Design: Prospective, uncontrolled treatment trial.Setting: University hospital referral center and three collaborating university and community hospitals.Patients: 34 patients with stage I or stage II N1 gastric MALT lymphoma.Intervention: Two of three oral antibiotic regimens--1) amoxicillin, 750 mg three times daily, and clarithromycin, 500 mg three times daily; 2)tetracycline, 500 mg four times daily, and clarithromycin, 500 mg three times daily; or 3) tetracycline, 500 mg four times daily, and metronidazole, 500 mg three times daily--were administered sequentially (usually in the order written) for 21 days at baseline and at 8 weeks, along with a proton-pump inhibitor (lansoprazole or omeprazole) and bismuth subsalicylate.Measurements: Complete remission was defined as the absence of histopathologic evidence of lymphoma on endoscopic biopsy. Partial remission was defined as a reduction in endoscopic tumor stage or 50% reduction in the size of large tumors.Results: 34 patients were followed for a mean (+/-SD) of 41 +/- 16 months (range, 18 to 70 months) after antibiotic treatment. Of 28 H. pylori-positive patients, 14 (50% [95% CI, 31% to 69%]) achieved complete remission, 8 (29%) achieved partial remission (treatment eventually failed in 4 of the 8), and 10 (36% [CI, 19% to 56%]) did not respond to treatment. Treatment failed in all 6 (100% [CI, 54% to 100%]) H. pylori-negative patients. Patients with endoscopic appearance of gastritis (stage I T1 disease) were most likely to achieve complete remission within 18 months. Tumors in the distal stomach were associated with more favorable response than tumors in the proximal stomach.Conclusions: A subset of H. pylori-positive gastric MALT lymphomas, including infiltrative tumors, may respond to antibiotics. The likelihood of early complete remission seems to be greatest for superficial and distal tumors. [ABSTRACT FROM AUTHOR]

Abstract Introduction Because tumors in the abdomen can change position, targeting these tumors for radiation therapy should be done with caution; use of daily image-guided radiation therapy is advised. Case presentation We report the case of a 72-year-old Caucasian man with recurrent mantle cell lymphoma who was referred for palliative radiation therapy for an abdominopelvic tumor. Computed tomography was used to generate images for radiation treatment planning. Comparison of those planning images with a positron emission tomography/computed tomography scan ordered during the planning period revealed that the tumor had moved from one side of the abdomen to the other during the three-day interval between scans. To account for this unusual tumor movement, we obtained a second set of planning computed tomography scans and used a Varian cone-beam computed tomography scanner with on-board imaging capability to target the tumor before each daily treatment session, leading to successful treatment and complete resolution of the mass. Conclusion Abdominal masses associated with the mesentery should be considered highly mobile; thus, radiation therapy for such masses should be used with the utmost caution. Modern radiation therapy techniques offer the ability to verify the tumor location in real time and shift the treatment ports accordingly over the course of treatment.

Introduction: Few studies exist on thyroid status and ovarian dysfunction, although the prevalence of thyroid disease, particularly hypothyroidism, increases with advanced age and is more common in women. Loss of ovarian function is a lengthy process, and it is well known that follicle-stimulating hormone (FSH) increases with age and is correlated with loss of ovarian reserves. Limited information is available on FSH and thyroid-stimulating hormone (TSH) status in healthy euthyroid women in pre- and postmenopause states. We propose that patterns in FSH levels depend on the menopause state and that a possible relationship with TSH is present in mature women.Methods: Baseline data from the study Health and Menopause in Hispanic Women in Puerto Rico were used. Eligible women were 30-84 years old. Demographic data and lifestyle and health information were collected through a questionnaire, and blood chemistries were analyzed.Results: In women without thyroid disease, the median TSH was 1.97 mIU/L, and for euthyroid women the median was 1.84 mIU/L; no difference was observed between pre- and postmenopause states. A positive tendency was found between FSH levels and age in this group.Conclusions: This report compares the value of TSH in Puerto Rican women during pre- and postmenopausal states, and our findings are different from those in other ethnic groups. FSH levels correlate with age, and the general tendency of FSH to increase with age differs according to menopause state. No correlation between TSH and FSH levels was found in this study.

Background: Brentuximab vedotin (BV) is a key therapeutic agent for patients with relapsed/refractory classical Hodgkin lymphoma (cHL). The outcomes of patients experiencing disease progression after BV are poorly described. Patients and methods: We reviewed our institutional database to identify patients with cHL treated with BV who were either refractory to treatment or experienced disease relapse. We collected clinicopathologic features, treatment details at progression and outcome. Results: One hundred patients met inclusion criteria, with a median age of 32 years (range 18-84) at progression after BV. The median number of treatments before BV was 3 (range 0-9); 71 had prior autologous stem cell transplant. The overall response rate (ORR) to BV was 57%, and the median duration of BV therapy was 3 months (range 1-25). After disease progression post-BV, the most common treatment strategies were investigational agents (n = 30), gemcitabine (n = 15) and bendamustine (n = 12). The cumulative ORR to therapy was 33% (complete response 15%). After a median follow-up of 25 months (range 1-74), the median progression-free (PFS) and overall survival (OS) were 3.5 and 25.2 months, respectively. In multivariate analysis, no factors analyzed were predictive of PFS; age at progression >45 years and serum albumin <40 g/l at disease progression were associated with increased risk of death. Among patients who achieved response to therapy, allogeneic stem cell transplantation was associated with a non-significant trend toward superior OS (P=0.11). Conclusions: Patients with BV-resistant cHL have poor outcomes. These data serve as a reference for newer agents active in BV-resistant disease. [ABSTRACT FROM AUTHOR]

There is limited research concerning the transgender population's health issues, such as gender dysphoria, and disparities within the healthcare system, especially in the Latino or Hispanic population. This study aimed to report the case of a Puerto Rican transgender man who achieved pregnancy without reproductive assistance after cessation of testosterone therapy for 3 months and who in the postpartum period experienced significant gender dysphoria. A narrative literature review was carried out to identify the role of gender dysphoria in pregnancy, lactation, health-related spaces, and mental health. Gender dysphoria is an important component of reproductive care in this population and can be accompanied by mental health issues that can directly impact the preconception, conception, and postpartum periods. The identification of gender dysphoria and how to properly manage it during pregnancy in transgender individuals can aid in the process of providing affirming and inclusive reproductive health care to this population., (© 2025 International Federation of Gynecology and Obstetrics.)

A wide selection of behavioral assays in systems neuroscience relies on head-fixation protocols to integrate in vivo multi-photon imaging approaches. For this, simultaneous pupillometry and locomotion tracking in head-fixed mice are used to measure behavioral responses and identify neural correlates. Here, we present an open-source protocol for assembling a complete head-fixation system that integrates pupillometry and locomotion-estimated tracking with multi-photon calcium imaging. We include detailed procedures for head-fixation and for data collection., Competing Interests: Declaration of interests N.C.P. and J.R.-R. are co-founders of a company (Carolina Instruments, LLC) with a potential commercial interest in the technology presented in this manuscript., (Copyright © 2024 The Author(s).

Anxiety disorders are prevalent and debilitating conditions characterized by excessive concern and fear, affecting thoughts, behaviors, and sensations. A critical component of anxiety is arousal, a complex process involving alertness regulation and stimulus salience modulation. While arousal is adaptive in normal circumstances, dysregulation can lead to hypoarousal or hyperarousal, affecting response selection and threat perception. This chapter reviews challenges in studying arousal in preclinical anxiety models, emphasizing the need for multicomponent measurement and analysis. Novel methodologies integrating physiological measurement with activity tracking of neurons with single-cell resolution in awake animals are discussed, with emphasis in current challenges. Understanding these mechanisms is crucial for developing effective treatments for anxiety disorders., (© 2024. The Author(s), under exclusive license to Springer Nature Switzerland AG.)

Social interactions are fundamental for our survival as a predominately social species. We need and seek positive social interactions to navigate the world. However, when social interactions are negative, and occur in the presence of an aversive event, learning occurs to associate such social interactions as threatening. Gaining insight into the neural circuits that drive social threat learning is crucial for understanding social interactions. Animal models can be leveraged to employ technologies that allow us to track neuronal processes with very high resolution to obtain a better understanding of the neural circuits involved. To accomplish this, we need robust behavioral models that are replicable and high throughput. Here, we present an open-source social interaction chamber that detects social interaction and automatically pairs it with foot shock. The social interaction chamber is designed to easily integrate into modular chambers commonly used for auditory and context threat learning. It contains an array of optical gates that precisely track mouse-to-mouse interactions in real time with digital triggers that can communicate with external devices to deliver a foot shock. We find that pairing social interactions with electric foot shock using our fully automated social interaction chamber is optimal for social threat associations. We further demonstrate that timing of social contact with foot shock produces optimal learning., Competing Interests: EM, NP and JR-R are co-founders of a company (Carolina Instruments, LLC) with a potential commercial interest in the technology presented in this manuscript.

Effectively assessing the realism and naturalness of images in virtual (VR) and augmented (AR) reality applications requires Full Reference Image Quality Assessment (FR-IQA) metrics that closely align with human perception. Deep learning-based IQAs that are trained on human-labeled data have recently shown promise in generic computer vision tasks. However, their performance decreases in applications where perfect matches between the reference and the distorted images should not be expected, or whenever distortion patterns are restricted to specific domains. Tackling this issue necessitates training a task-specific neural network, yet generating human-labeled FR-IQAs is costly, and deep learning typically demands substantial labeled data. To address these challenges, we developed ConIQA, a deep learning-based IQA that leverages consistency training and a novel data augmentation method to learn from both labeled and unlabeled data. This makes ConIQA well-suited for contexts with scarce labeled data. To validate ConIQA, we considered the example application of Computer-Generated Holography (CGH) where specific artifacts such as ringing, speckle, and quantization errors routinely occur, yet are not explicitly accounted for by existing IQAs. We developed a new dataset, HQA1k, that comprises 1000 natural images each paired with an image rendered using various popular CGH algorithms, and quality-rated by thirteen human participants. Our results show that ConIQA achieves superior Pearson (0.98), Spearman (0.965), and Kendall's tau (0.86) correlations over fifteen FR-IQA metrics by up to 5%, showcasing significant improvements in aligning with human perception on the HQA1k dataset., (© 2024.

Traumatic social experiences redefine socially motivated behaviors to enhance safety and survival. Although many brain regions have been implicated in signaling a social threat, the mechanisms by which global neural networks regulate such motivated behaviors remain unclear. To address this issue, we first combined traditional and modern behavioral tracking techniques in mice to assess both approach and avoidance, as well as sub-second behavioral changes, during a social threat learning task. We were able to identify previously undescribed body and tail movements during social threat learning and recognition that demonstrate unique alterations into the behavioral structure of social motivation. We then utilized inter-regional correlation analysis of brain activity after a mouse recognizes a social threat to explore functional communication amongst brain regions implicated in social motivation. Broad brain activity changes were observed within the nucleus accumbens, the paraventricular thalamus, the ventromedial hypothalamus, and the nucleus of reuniens. Inter-regional correlation analysis revealed a reshaping of the functional connectivity across the brain when mice recognize a social threat. Altogether, these findings suggest that reshaping of functional brain connectivity may be necessary to alter the behavioral structure of social motivation when a social threat is encountered.

Social phobia is highly detrimental for social behavior, mental health, and productivity. Despite much previous research, the behavioral and neurobiological mechanisms associated with the development of social phobia remain elusive. To investigate these issues, the present study implemented a mouse model of social threat conditioning in which mice received electric shock punishment upon interactions with unfamiliar conspecifics. This resulted in immediate reductions in social behavior and robust increases in defensive mechanisms such as avoidance, freezing, darting, and ambivalent stretched posture. Furthermore, social deficits lasted for prolonged periods and were independent of contextual settings, sex variables, or particular identity of the social stimuli. Shedding new light into the neurobiological factors contributing to this phenomenon, we found that optogenetic silencing of the prelimbic (PL), but not the infralimbic (IL), subregion of the medial prefrontal cortex (mPFC) during training led to subsequent forgetting and development of lasting social phobia. Similarly, pharmacological inhibition of NMDARs in PL also impaired the development of social phobia. These findings are consistent with the notion that social-related trauma is a prominent risk factor for the development of social phobia, and that this phenomenon engages learning-related mechanisms within the prelimbic prefrontal cortex to promote prolonged representations of social threat.

Objective: This study aimed to assess the knowledge and attitudes of a sample of Hispanics in Puerto Rico (PR) toward the transgender community., Methods: A cross-sectional study addressing Hispanics, aged 21 years or older who lived in PR, was performed from March to September 2021. Participants were invited through online advertisement shared on social media pages. Data were collected via SurveyMonkey and analyzed with Stata 17. Descriptive statistics were employed to summarize findings., Results: A total of 404 participants were sampled. Most were female, 278 (68.8%), had completed at least a bachelor's degree, 292 (72.2%), and referred exposure to trans-related topics during education, 237 (58.7%). Most correctly defined the terms sex, 257 (63.6%), sexual orientation, 334 (82.7%) and transgenderism, 297 (73.5%). The majority also agreed that transgender individuals should be able to change their name, 353 (93.6%) and undergo gender-affirming procedures, 335 (88.9%). Most also believed trans individuals were a valuable part of society, 339 (89.9%) and should be allowed free gender expression, 358 (95.0%)., Conclusions: PR is characterized by a patriarchal, religious, and conservative culture which could promote a negative attitude toward transgender people. Our findings challenged such assumption. The level of knowledge and positive attitude toward trans individuals identified in this study could counteract the existing violence and stigma affecting this community in PR., (© 2024 International Federation of Gynecology and Obstetrics.)

As the SARS-CoV-2 virus spread throughout the world, millions of positive cases of COVID-19 were registered and, even though there are millions of people already vaccinated against SARS-CoV-2, a large part of the global population remains vulnerable to contracting the virus. Massive nasopharyngeal sample collection in Puerto Rico at the beginning of the pandemic was limited by the scarcity of trained personnel and testing sites. To increase SARS-CoV-2 molecular testing availability, we evaluated the diagnostic accuracy of self-collected nasal, saliva, and urine samples using the TaqPath reverse transcription polymerase chain reaction (RT-PCR) COVID-19 kit to detect SARS-CoV-2. We also created a colorimetric loop-mediated isothermal amplification (LAMP) laboratory developed test (LDT) to detect SARS-CoV-2, as another strategy to increase the availability of molecular testing in community-based laboratories. Automated RNA extraction was performed in the KingFisher Flex instrument, followed by PCR quantification of SARS-CoV-2 on the 7500 Fast Dx RT-PCR using the TaqPath RT-PCR COVID-19 molecular test. Data was interpreted by the COVID-19 Interpretive Software from Applied Biosystems and statistically analyzed with Cohen's kappa coefficient (k). Cohen's kappa coefficient (k) for paired nasal and saliva samples showed moderate agreement (0.52). Saliva samples exhibited a higher viral load. We also observed 90% concordance between LifeGene-Biomarks' SARS-CoV-2 Rapid Colorimetric LAMP LDT and the TaqPath RT-PCR COVID-19 test. Our results suggest that self-collected saliva is superior to nasal and urine samples for COVID-19 testing. The results also suggest that the colorimetric LAMP LDT is a rapid alternative to RT-PCR tests for the detection of SARS-CoV-2. This test can be easily implemented in clinics, hospitals, the workplace, and at home; optimizing the surveillance and collection process, which helps mitigate global public health and socioeconomic upheaval caused by airborne pandemics., (© 2024 LifeGene Biomarks.

With the expansion of human microbiome studies in the last 15 years, we have realized the immense implications of microbes in human health. The human holobiont is now accepted, given the commensal relationships with bacteria, fungi, parasites, viruses, and human cells. The cervicovaginal microbiota is a specific case within the human microbiome where diversity is lower to maintain a chemical barrier of protection against infections. This narrative review focuses on the vaginal microbiome. It summarizes key findings on how native bacteria protect women from disease or predispose them to damaging inflammatory processes with an emphasis on the role of HPV infections in Latin America, one of the world's regions with the highest cervical cancer prevalence.

Cervical cancer (CC) is women's fourth most common cancer worldwide. A worrying increase in CC rates in Hispanics suggests that besides Human papillomavirus infections, there may be other cofactors included in the epithelial microenvironment that could play a role in promoting the disease. We hypothesized that the cervical microbiome and the epithelial microenvironment favoring inflammation is conducive to disease progression in a group of Hispanics attending gynecology clinics in Puerto Rico. Few studies have focused on the joint microbiota and cytokine profile response in Hispanics outside the US, especially regarding the development of precancerous lesions. We aimed to investigate the relationship between the cervicovaginal microbiome and inflammation in Hispanic women living in PR while considering cervical dysplasia and HPV genotype risk. Cervical samples collected from 91 participants coming to gynecology clinics in San Juan, underwent 16S rRNA genes (V4 region) profiling, and cytokines were measured using Luminex MAGPIX technology. Cytokines were grouped as inflammatory (IL-1β, TNFα, IFNγ, IL-6), anti-inflammatory (IL- 4, IL-10, TGFβ1), and traffic-associated (IL-8, MIP1a, MCP1, IP10). They were related to microbes via an inflammation scoring index based on the quartile and tercile distribution of the cytokine's concentration. We found significant differences in the diversity and composition of the microbiota according to HPV type according to carcinogenic risk, cervical disease, and cytokine abundance. Community State Types (CSTs) represents a profile of microbial communities observed within the vaginal microbiome ecological niche, and Lactobacillus-depleted CST IV had ~ 90% dominance in participants with high-grade squamous intraepithelial lesions and high-risk HPV. The increasing concentration of pro-inflammatory cytokines was associated with a decrease in L. crispatus. In contrast, dysbiosis-associated bacteria such as Gardnerella, Prevotella, Atopobium concomitantly increased with pro-inflammatory cytokines. Our study highlights that the cervical microbiota of Hispanics living in Puerto Rico is composed mostly of diverse CST profiles with decreased Lactobacillus and is associated with a higher pro-inflammatory environment. The joint host-microbe interaction analyses via cytokine and microbiota profiling have very good translational potential., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Tosado-Rodríguez et al.

Objective: The primary aim of this cross-sectional study was to assess, according to previous cancer diagnosis, the knowledge Puerto Rican women have on the link between obesity-endometrial, -breast, and colon cancer, and determine women's most common source for medical information., Methods: In this cross-sectional study, eligible female patients (n=234) from the Gynecology and Gynecology-Oncology Clinics completed a self-administered survey from October 2014 to March 2016. Participants were evaluated on sociodemographic, body mass index, knowledge of the obesity-cancer link, and source of medical information., Results: About 49% and 31% of women in the study were obese and overweight, respectively. Less than 52% of the women knew about the link between obesity-breast,-colon, and/or -endometrial cancers. Women with previous cancer diagnoses were more likely aware of the association between obesity-colon cancer than women without previous cancer diagnoses (58% vs. 44%, p0.05). Higher incomes showed increased odds for the knowledge obesity-cancer link among women with a cancer history, but the odds decreased for women without previous cancer diagnoses (p>0.05). Higher education showed a trend towards a better knowledge of the obesity-cancer association. The most common sources of information were the primary doctor (80%) and the internet (54%)., Conclusion: Counseling about preventable cancer risk factors through primary care to all women must be encouraged especially in young healthy females. Further studies should address qualitative aspects of the odds differences in the obesity-cancer link knowledge observed between income categories for women with/without previous cancer diagnoses.

Objective: Past studies have demonstrated that women with inflammatory bowel disease (IBD) have a higher risk of gynecological conditions than do women without it. We aimed to characterize the gynecological histories of Hispanic Women living in Puerto Rico with IBD., Methods: We identified women, aged 21 to 55 years, with a confirmed IBD diagnosis and receiving follow-up care from the University of Puerto Rico IBD clinics from 2017 through 2020. A questionnaire was administered to acquire sociodemographics, family history, past medical history, IBD diagnosis, and gynecologic aspects., Results: One hundred eighty-six women were recruited. Fifty-three (28%) patients had ulcerative colitis, while 133 (72%) had Crohn's disease. Fifty-six percent of all the participants had a chronic illness in addition to than their IBD. Seventy-four out of 186 patients reported having had at least 1 late period within the last 12 months. Fifty-three (28%) described their period patterns as irregular. Thirty-nine (21%) of the patients reported having been vaccinated against human papillomavirus (HPV), and 8 (4%) had been infected by it. Nine out of 186 (5%) patients reported suffering from infertility., Conclusion: The results showed that our Hispanic patients (living in Puerto Rico) had a prevalence of irregular menstrual cycles that was similar to that observed in other populations. On the other hand, the presence of HPV, infertility, and cervical cancer were lower and the frequency of Papanicolaou smears performed higher than what has been seen in the continental United States, suggesting that this topic should be investigated in future studies.

The cervicovaginal microbiota is influenced by host physiology, immunology, lifestyle, and ethnicity. We hypothesized that there would be differences in the cervicovaginal microbiota among pregnant, nonpregnant, and menopausal women living in Puerto Rico (PR) with and without human papillomavirus (HPV) infection and cervical cancer. We specifically wanted to determine if the microbiota is associated with variations in cervical cytology. A total of 294 women, including reproductive-age nonpregnant ( N = 196), pregnant ( N = 37), and menopausal ( N = 61) women, were enrolled. The cervicovaginal bacteria were characterized by 16S rRNA amplicon sequencing, the HPV was genotyped with SPF10-LiPA, and cervical cytology was quantified. High-risk HPV (HR-HPV, 67.3%) was prevalent, including genotypes not covered by the 9vt HPV vaccine. Cervical lesions (34%) were also common. The cervical microbiota was dominated by Lactobacillus iners . Pregnant women in the second and third trimesters exhibited a decrease in diversity and abundance of microbes associated with bacterial vaginosis. Women in menopause had greater alpha diversity, a greater proportion of facultative and strictly anaerobic bacteria, and higher cervicovaginal pH than premenopausal women. Cervical lesions were associated with greater alpha diversity. However, no significant associations between the microbiota and HPV infection (HR or LR-HPV types) were found. The cervicovaginal microbiota of women living in Puerto Rican were either dominated by L. iners or diverse microbial communities regardless of a woman's physiological stage. We postulate that the microbiota and the high prevalence of HR-HPV increase the risk of cervical lesions among women living in PR. IMPORTANCE In the enclosed manuscript, we provide the first in-depth characterization of the cervicovaginal microbiota of Hispanic women living in Puerto Rico (PR), using a 16S rRNA approach, and include women of different physiological stages. Surprisingly we found that high-risk HPV was ubiquitous with a prevalence of 67.3%, including types not covered by the 9vt HPV vaccine. We also found highly diverse microbial communities across women groups-with a reduction in pregnant women, but dominated by nonoptimal Lactobacillus iners . Additionally, we found vaginosis-associated bacteria as Dialister spp., Gardnerella spp., Clostridium , or Prevotella among most women. We believe this is a relevant and timely article expanding knowledge on the cervicovaginal microbiome of PR women, where we postulate that these highly diverse communities are conducive to cervical disease., Competing Interests: The authors declare no conflict of interest.

Objective: To understand the impact of the COVID-19 pandemic on the prenatal care of pregnant Hispanic women living in Puerto Rico., Methods: This was a cross-sectional study. The participants' profiles were determined through an online questionnaire to analyze COVID-19 related behaviors and experiences., Results: Our sample comprised 131 women with an average age of 28 years (±5.3 years). Most of the population was pregnant at the time of the interview (74.8%; n = 98), and the rest were in their post-partum period. Overall, 46.5% (n = 61) of the patients indicated that their prenatal care did not change during the pandemic. In addition, 92.50% (n = 111) reported not altering their plans for breastfeeding their babies. Overall, 77.86% of the participants reported feeling scared or overwhelmed due to the current pandemic, and 97% agreed that COVID testing should be performed as a screening method in all pregnant females., Conclusion: Our findings describe the characteristics of pregnant Hispanic females living in Puerto Rico. The majority reported adhering adequately to their health services, with few or no changes in their prenatal care.

Objective: To assess the contraceptive methods used by sexually active Hispanic women living in Puerto Rico., Methods: From October 2016 through February 2018, 518 patients completed a self-administered questionnaire. The inclusion criteria were being over the age of 21 and having visited San Juan City Hospital or University District Hospital. The results were analyzed using descriptive statistics and a 2-sample t test, where P < .05 was considered significant., Results: A total of 518 participants completed the questionnaire. Of the 518, 413 (81.0%) reported having used at least 1 form of contraception; 252 (49.4%) used OCPs, 305 (60.8%) used male condoms, 92 (33.8%) used the rhythm method, 83 (30.6%) undergone female sterilization, 98 (19.9%) used the withdrawal method, 92 (18.9%%) used an implant, 67 (13.5%) received progesterone injections, 41 (8.3%) used female condoms, 13 (4.9%) had partners who undergone male sterilization, 20 (4.1%) used the transdermal patch, 16 (3.2%) used a vaginal ring, and 26 (5.3%) used an intrauterine device., Conclusion: Of the 518 women, 24.2% used LARC, representing an increase in the usage by this population; this increase is likely linked to LARC's being easily accessible and free of charge. Public health interventions should be developed to increase knowledge about sexual health, educate about the effectiveness of different contraceptive methods and the prevention of sexually transmitted diseases, and reduce both the barriers to acquiring contraception and, thereby, the number of unintended pregnancies in this population.

Objective: To investigate the association between sexual orientation and sexual violence in Hispanic women living in Puerto Rico., Methods: Secondary data analysis of a cross-sectional study. An anonymous web-based questionnaire was distributed in Puerto Rico between February and April 2016. Variables included history of sexual violence, sexual orientation, and age of first sexual experiences. Data were analyzed using χ 2 testing and a P value less than 0.05 was considered significant., Results: Sociodemographic characteristics were similar between groups except for age in the 476 participants. The most common age of first sexual experiences was between 7 and 12 years, 13-18 years for penile vaginal and oral sex, and 22-29 years for penile anal sex in the overall population of the study. These did not differ except that more bisexual women 40 (71.4%) had their first oral sex experience at 13-18 years compared with 164 (50.7%) heterosexual and 35 (55.2%) lesbian women (P = 0.045). Of the 19.2% of participants who reported sexual violence, there were 50 (18.4%) heterosexual, 8 (12.2%) lesbian, and 17 (34.7%) bisexual women. Bisexual women were more likely to disclose sexual violence (P = 0.007)., Conclusion: Most women stated having a sexual experience at a young age. Significant proportions reported sexual violence with bisexual women being the most likely. Screening for sexual violence must be routinely performed by health professionals., (© 2022 International Federation of Gynecology and Obstetrics.)

Objectives: Our study investigates the psychosexual impact of human papillomavirus (HPV) diagnosis and its associated conditions on Hispanic women living in Puerto Rico., Materials and Methods: A cross-sectional quantitative study was conducted on 205 women between 21 and 65 years old who received services at the Gynecology Clinics of the Medical Sciences Campus from April 2019 to December 2019. After obtaining approval from the institutional review board (March 27, 2019) and the informed consent of participants, participants completed a sociodemographic questionnaire and 4 psychological symptomatology-based questionnaires that measured levels of anxiety, depression, sexual satisfaction, and self-esteem., Results: Of the participants, 48.8% had a known diagnosis of HPV ( n = 100) compared with 51.2% without a known HPV diagnosis ( n = 105). A Mann-Whitney U test analysis for independent samples was used, which showed that patients with known HPV diagnoses had higher reported levels of anxiety in the Generalized Anxiety Disorder Scale with a statistical significance of 0.03, as compared with patients without a known HPV diagnosis. There was no significant difference in reported levels of depressive symptoms, self-esteem, or sexual satisfaction between the groups., Conclusions: Our findings show that in this group of Hispanic women living in Puerto Rico, being diagnosed with HPV and its associated conditions can be associated with higher anxiety symptoms. Further studies are warranted in this population to help improve their health outcomes and access to proper primary and preventive care., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2022, ASCCP.)

Background: Access to the full spectrum of healthcare should be available to all individuals. After the revocation of the constitutional right to abortion, women have fewer alternatives to unplanned pregnancy. Telehealth provides an additional option for such pregnancies through its remote provision of services. This could benefit women of all social strata. However, data regarding telehealth among underserved populations are limited., Objective: This study aimed to evaluate the use of contraception, awareness of abortion services, and receptiveness to telehealth among women in Puerto Rico, a Spanish-speaking minority population., Study Design: This was a cross-sectional study of women living in Puerto Rico aged between 21 and 65 years. Data were collected with a self-administered survey via SurveyMonkey from March to December of 2021. Recruitment was done through social media and at the gynecology clinics of the University of Puerto Rico, Medical Sciences Campus and San Juan City Hospital. Analysis was done with Stata, version 14.2. Chi-square and Cochran-Armitage tests were used to evaluate the unadjusted relationship between variables. A P value ≤.05 was considered statistically significant., Results: A total of 286 women were recruited. Of these, 73.3% (189/258) were sexually active, 89.1% (229/257) were heterosexual, and 62.7% (163/260) were not using contraception. In addition, 63.3% (157/248) knew about emergency contraception, yet 42.4% (103/243) were unaware of any sources of access to it; 76.6% (197/257) were unaware of nearby abortion services. A higher education level was associated with knowing about emergency contraception ( P <.05) and awareness of sources of access to it ( P <.05). However, no significant association was found between a higher education level and awareness of nearby abortion services ( P =.799). Regarding telehealth, 65.2% (176/270) were willing to use the service for future gynecologic visits, yet only 18.9% (51/269) were offered telehealth services. No association was found between previous telehealth experiences and willingness to use telehealth for future gynecologic visits ( P =.325)., Conclusion: The lack of contraceptive use and unawareness of nearby abortion services place women at increased risk of unplanned pregnancy and unsafe practices. The gap between knowledge about and access to emergency contraception also calls for action. Telehealth may be of benefit given that most women showed interest in using it, and could be used for educating and providing women in Puerto Rico with contraception and medical abortions, further increasing their access to reproductive healthcare. Clarifying misconceptions and instructing women about safe practices is essential to our role as physicians. Ensuring women's access to adequate services is also vital for upholding their rights to healthcare., (© 2022 The Authors.)

Genetically encoded calcium indicators and optogenetics have revolutionized neuroscience by enabling the detection and modulation of neural activity with single-cell precision using light. To fully leverage the immense potential of these techniques, advanced optical instruments that can place a light on custom ensembles of neurons with a high level of spatial and temporal precision are required. Modern light sculpting techniques that have the capacity to shape a beam of light are preferred because they can precisely target multiple neurons simultaneously and modulate the activity of large ensembles of individual neurons at rates that match natural neuronal dynamics. The most versatile approach, computer-generated holography (CGH), relies on a computer-controlled light modulator placed in the path of a coherent laser beam to synthesize custom three-dimensional (3D) illumination patterns and illuminate neural ensembles on demand. Here, we review recent progress in the development and implementation of fast and spatiotemporally precise CGH techniques that sculpt light in 3D to optically interrogate neural circuit functions., (© 2022 The Authors.)

Objective: The aim of this study was to explore the knowledge and attitudes about transgender care in Hispanic medical students at the University of Puerto Rico School of Medicine (UPR SOM)., Methods: Medical students at the UPR SOM were invited to participate in a questionnaire to assess their attitudes and knowledge about the healthcare of transgender patients. The data were analyzed as percentages and averages using Stata version 14., Results: A total of 141 medical students completed the survey. The majority of the students (52.5%) reported that they needed to learn more about transgender health issues. Most of the students (60.3%) were not familiar with the hormonal regimens used for gender reassignment and transition and were not knowledgeable about the requirements an individual must fulfil prior to undergoing gender-reassignment surgery. The Likert scale scores for how comfortable students felt about working with transgender patients and becoming known among peers as a doctor that cares for transgender patients were 4.0 (95% CI: 4.0-4.2) and 4.7 (95% CI: 4.6-4.8), respectively. Almost all the medical students (97.9%) thought that transgender patients deserved the same quality of care from medical institutions as heterosexual patients receive. Most of the medical students (87.3%) believed physicians are responsible for the treatment of transgender patients., Conclusion: Our study revealed that even though UPR SOM medical students tend to be willing to treat transgender patients, there are limitations to their knowledge and training regarding this specific healthcare topic. Strategies to improve medical student knowledge about and training on these topics must be considered.
