RESUMO
Emotional disorders (ED) such as anxiety, depression and somatization are extremely prevalent disorders that can affect an individual's quality of life and functionality. Primary Health Care (PHC) is the first place to identify most patients with these conditions. Mental health services in the Dominican Republic, as well as in Latin America and the Caribbean in general, are unable to provide appropriate care for most people with mental disorders. Using evidence-based treatment protocols is also crucial to make progress in helping people with ED. The PsicAP project is a group intervention that uses a transdiagnostic approach and is grounded in cognitive-behavioral techniques. The program is implemented in 7 group sessions, each lasting for one and a half hours. The program has been shown to be effective in reducing clinical symptoms, dysfunction, and in improving quality of life. It is also a non-time-intensive, low-cost treatment that is helpful for addressing EDs in a PHC context. The objective is to bring psychological treatments into PHC facilities of Dominican Republic, making them more accessible for a larger amount of the population.

During the coronavirus outbreak, it was noted that pre-existing psychological illnesses worsened, and numerous research indicate that those with contamination-related obsessions and cleaning compulsions (C-OCD) may be more affected. Virtual Reality (VR) and other immersive technologies have shown to be effective for the treatment of disorders related to anxiety, thus showing their potential to transform OCD treatment by means of integrating virtual elements. VR exposure has shown benefits compared to live or imagined exposure, however, to be effective it must be able to elicit high emotional arousal in users. Based on this, the present work aimed to develop different virtual environments scenarios and evaluate their efficacy in generating an emotional response in people with C-OCD symptoms. Based on the literature review, two virtual scenarios were created (dirty public bathroom and unhygienic kitchen). Subsequently, two groups were then constituted: C-OCD group (n = 20, aged between 18 and 48 years) characterized by an obtained score of more than 13 points (cut-point) in the Yale-Brown Scale for Obsessive-Compulsive Disorder (Y-BOCS) and by showing C-OCD symptoms when doing the structured interview (SCID-I), and a control group (n = 20, aged between 18 and 56 years), all participants were residents of the Dominican Republic. Exposure to the virtual environments generated high levels of state and subjective anxiety in both groups, although significantly higher in the C-OCD group. The results obtained indicate that the VR scenarios developed are suitable for eliciting emotional responses and, consequently, that they can be used to complement the treatment of C-OCD.
RESUMO
BACKGROUND/INTRODUCTION: Psychological and physical well-being of health personnel has been significantly affected by COVID-19. Work overload and continuous exposure to positive COVID-19 cases have caused them fatigue, stress, anxiety, insomnia and other detriments. This research aims: 1) to analyze whether the use of cognitive reevaluation and emotional suppression strategies decreases and increases, respectively, stress levels of health personnel; 2) to quantify the impact of contact with patients with COVID-19 on stress levels of medical staff. METHOD: Emotion regulation strategies (cognitive reevaluation and emotional expression) and stress levels were evaluated in 155 Dominican physicians who were treating people infected with COVID-19 at the moment of the study (67.9% women and 32.1% men; mean age = 34.89; SD = 9.26). In addition, a questionnaire created by the researchers quantified the impact that contact with those infected had on their stress levels. RESULTS: Contact with patients with COVID-19 predicts increased use of emotion suppression strategies, although is not associated with the use of cognitive reevaluation. These findings lead to an even greater increase in stress on health care providers. CONCLUSIONS: Contextual contingencies demand immediate responses and may not allow health personnel to use cognitive re-evaluation strategies, leaning more towards emotion suppression. However, findings regarding high levels of stress require the implementation of intervention programs focused on the promotion of more functional emotion regulation strategies. Such programs may reduce current stress and prevent post-traumatic symptoms.

A common method to collect information in the behavioral and health sciences is the self-report. However, the validity of self-reports is frequently threatened by response biases, particularly those associated with inconsistent responses to positively and negatively worded items of the same dimension, known as wording effects. Modeling strategies based on confirmatory factor analysis have traditionally been used to account for this response bias, but they have recently become under scrutiny due to their incorrect assumption of population homogeneity, inability to recover uncontaminated person scores or preserve structural validities, and their inherent ambiguity. Recently, two constrained factor mixture analysis (FMA) models have been proposed by Arias et al. (2020) and Steinmann et al. (2021) that can be used to identify and screen inconsistent response profiles. While these methods have shown promise, tests of their performance have been limited and they have not been directly compared. Thus the objective of the current study was to assess and compare their performance with data from the Dominican Republic of the Rosenberg Self-Esteem Scale (N = 632). Additionally, as this scale had not yet been studied for this population, another objective was to show how using constrained FMAs could help in the validation of mixed-worded scales. The results indicated that removing the inconsistent respondents identified by both FMAs (≈8%) reduced the amount of wording effects in the database. However, whereas the Steinmann et al. method only cleaned the data partially, the Arias et al. (2020) method was able to remove the great majority of the wording effects variance. Based on the screened data with the Arias et al. method, we evaluated the psychometric properties of the RSES for the Dominican population, and the results indicated that the scores had good validity and reliability properties. Given these findings, we recommend that researchers incorporate constrained FMAs into their toolbox and consider using them to screen out inconsistent respondents to mixed-worded scales.
RESUMO
Fear to contamination is an easy-to-provoke, intense, hard-to-control, and extraordinarily persistent fear. A worsening of preexisting psychiatric disorders was observed during the COVID-19 (coronavirus disease 2019) outbreak, and several studies suggest that those with obsessive-compulsive disorder (OCD) may be more affected than any other group of people. In the face of worsening OCD symptoms, there is a need for mental health professionals to provide the support needed not only to treat patients who still report symptoms, but also to improve relapse prevention. In this line, it is recommended to improve alternative strategies such as online consultations and digital psychiatry. The aim of this study is to develop augmented reality (AR) stimuli that are clinically relevant for patients with cleaning OCD and assess their efficiency to obtain emotionally significant responses. Four AR stimuli were developed: a plastic bag full of garbage, a piece of bread with mold, a dirty sports shoe, and a piece of rotten meat. All stimuli were shown to a clinical group (17 patients with cleaning OCD) and a control group (11 patients without OCD). Relevant results were the design of the AR stimuli. These stimuli were validated with the statistical difference in perceived anxiety in the meat stimuli between the clinical and control groups. Nevertheless, when looking at effect sizes, all stimuli present effect sizes from small (plastic bag) to large (meat), with both shoe and bread between small and medium effect sizes. These results are a valuable support for the clinical use of these AR stimuli in the treatment of cleaning OCD.
RESUMO
Resumen Introducción: El síndrome de obstrucción hemivaginal y anomalía renal ipsilateral (OHVIRA, por sus siglas en inglés) o también llamado síndrome de Herlyn-Werner-Wunderlich es una rara malformación mulleriana que consiste en la presencia de útero didelfo, obstrucción hemivaginal y anomalía renal ipsilateral. La incidencia de malformaciones mullerianas son del 2 al 3%, y la menos común es el síndrome de OHVIRA. Objetivo: Descripción de un caso excepcional de alteraciones mullerianas poco conocido. Presentación del caso: Adolescente de 14 años con historia de dolor pélvico, dismenorrea e infecciones urinarias a repetición. Se estudió con gammagrafía renal que reveló agenesia renal derecha y resonancia magnética pélvica que mostró útero didelfo con hematocolpos derechos. Se confirmaron los hallazgos por laparoscopia diagnóstica. Conclusiones: Este síndrome es poco conocido. Debe sospecharse en casos de agenesia renal, dolor pélvico crónico y alteraciones menstruales en pacientes postpuberes. El abordaje es multidisciplinario.
Abstract Introduction: The obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome, also known as the Herlyn-Werner-Wunderlich syndrome, is a rare müllerian anomaly characterized by didelphic uterus, hemivaginal obstruction, and ipsilateral renal anomaly. The incidence of müllerian malformations is 2% - 3%, OHVIRA being the least common of these cases. Objective: To describe an exceptional case of a müllerian disorder. Case presentation: A 14-year-old adolescent with a history of pelvic pain, dysmenorrhea, and recurrent urinary infections. Renal gammagraphy analysis revealed right renal agenesis, and pelvic magnetic resonance imaging showed a didelphic uterus with right hematocolpos. These findings were confirmed by diagnostic laparoscopy. Conclusions: This syndrome is not well known. Renal anegesis, chronic pelvic pain, and menstrual abnormalities in post-pubertal patients must be presumed as indicators of OHVIRA, whose treatment requires a multidisciplinary approach.

BACKGROUND: Near-infrared spectroscopy (NIRS) is a noninvasive monitoring technique that measures regional cerebral oxygen saturation (rSO2). OBJECTIVES: The primary aim was to compare the output of 2 NIRS-based cerebral oximetry devices, FORESIGHT (CAS Medical Systems Inc, Branford, Connecticut) and INVOS (Covidien, Boulder, Colorado), to venous oxygen saturations from the jugular venous bulb at cannulation and decannulation of the superior vena cava (SVC). Secondary objectives included evaluating correlations of cerebral saturation, as measured by the NIRS devices, with mean arterial blood pressure (MAP), measured by an invasive arterial line, and end-tidal CO2 (ETCO2). METHODS: Near-infrared spectroscopy, MAP, and ETCO2 data were collected at 13 defined events during each case when hemodynamic instability was expected. At SVC cannulation and decannulation, a 0.1 mL sample of blood was collected from the jugular bulb by the surgeon using a long angiocatheter. The oxygen saturation of these blood samples was measured using an AVOX device and compared with contemporaneous readings from the NIRS probes. Mixed-effects linear regression was used to correlate MAP or ETCO2 with cerebral oxygen saturation (by NIRS) at each time point. RESULTS: Children undergoing cardiopulmonary bypass for congenital heart surgery (n = 34) were enrolled in the study. At SVC cannulation, both INVOS ( r = .78) and FORESIGHT ( r = .59) were correlated with AVOX data at P < .001, although the correlation with INVOS was significantly stronger ( P = .003). At SVC decannulation, INVOS ( r = .68; P < .001) and FORESIGHT ( r = .60; P < .001) were similarly correlated with jugular venous rSO2. Correlations of rSO2 (by NIRS) with MAP and ETCO2 levels were stronger than correlations between rSO2 change and change in MAP or ETCO2. CONCLUSION: INVOS correlated more strongly than FORESIGHT with the jugular bulb rSO2 at SVC cannulation but may have underestimated oxygen saturation at low rSO2 values. Data from both NIRS devices were correlated with MAP and ETCO2 over the case duration.

Se presentan dos pacientes sometidos a derivación ventricular por hidrocefalia idiopática y cisticercosis del cuarto ventrículo, respectivamente. En la resonancia magnética (RM) de control se encontró un aumento en el tamaño del cuerpo calloso con zonas de prolongación de los tiempos de relajación sin restricción en la secuencia de difusión. Las teorías fisiopatológicas mencionan: efectos mecánicos directos tras la colocación de la derivación, efecto compresivo crónico sobre el cuerpo calloso contra la hoz cerebral por la hidrocefalia, tracción de ramas perforantes de las arterias pericallosas que conduce a isquemia (probablemente ausente en estudios prequirúrgicos por el adelgazamiento del cuerpo calloso) y descompresión, luego de la derivación, que produce reexpansión del cuerpo calloso y edema intersticial del mismo. Los hallazgos pueden explicarse por el antecedente de derivación e hidrocefalia sin repercusión clínica aparente...

Los caldos selectivos con cisteina HCL 0.05 por ciento, cubiertos con parafina resularon ser mas efectivas para la inhibición de pseudomonas aeroginosa que los caldos cisteinadas sin cubiertas de parafina. El caldo selenita fue más efectivo para dicha inhibición que el calcio tetrationate. El agar desoxicolato citrato (incubado aeróbica o anaeróbicamente) resultó el más efectivo para la inhibición, especialmente cuando se aisló a partir de caldos cisteinados parafinadas. El agar verde brillante rojo de fenal-lactosa incubada aeróricamente tambien resultó util para dicha inhibición, cuando se aisló a partir de caldo solenito cisteinado y parafinado. Siendo no recomendable la incubación anaeróbica debido a las variaciones de forma y color de las colonias. El agar bismuto sulfito es muy buen medio de cultivo respecto a la diferenciación de las colonias de ambos microorganismos, pero no se logró inhibir totalmente el crecimiento de pseudomonas, aunque hubo una notable disminución del crecimiento, cuando se incubó el agar bajo condiciones anaeróbicas.
