Open science: Friend, foe, or both to an antiracist psychology?

The open science framework has garnered increased visibility and has been partially implemented in recent years. Open science underscores the importance of transparency and reproducibility to conduct rigorous science. Recently, several journals published by the American Psychological Association have begun adopting the open science framework. At the same time, the field of psychology has been reckoning with the current sociopolitical climate regarding anti-Blackness and White supremacy. As psychology begins to adopt the open science framework into its journals, the authors underscore the importance of embracing and aligning open science with frameworks and theories that have the potential to move the field toward antiracism and away from the embedded White supremacy value systems and ideals. The present article provides an overview of the open science framework; an examination of White supremacy ideology in research and publishing; guidance on how to move away from these pernicious values; and a proposal on alternate value systems to center equity, diversity, and inclusion with the aim of establishing an antiracist open science framework.

Tis study to analyze these variables with a view to finding a better therapeutic option. Te advantage is having a representative if not random sample, strict follow-up, and appropriate statistical analysis Conclusion: Intrathecal Clonidine proved to be more effective in immediate postoperative pain management after posterior lumbosacral spine surgery and with fewer adverse effects

Acculturated and acultura'os: Testing bidimensional acculturation across central Florida and island Puerto Ricans.

OBJECTIVES: Two studies and data sources were used to empirically compare and cross-validate three bidimensional acculturation measurement models. METHOD: Following a cross-sectional design and confirmatory factor analysis (CFA), Study 1 examined the models in a sample of Central Florida Puerto Ricans (n = 484). In Study 2, the measurement model was retested on a separate sample of island Puerto Ricans (n = 399). To ensure adequate comparisons across the two samples, measurement invariance tests were performed. RESULTS: A bidimensional six-factor model (B6F) resulted in the best model fit for both samples. Results indicated full configural, metric, uniqueness, factor variance, covariance, and partial scalar invariance between the 2 groups. An examination of mean differences between the samples revealed that Central Florida Puerto Ricans had a significantly stronger endorsement of Puerto Rican and European American values than those living in the island. CONCLUSIONS: This examination revealed that both groups share the same acculturation structure. That is, acculturation among Central Florida and island Puerto Ricans can be conceptualized as a bidimensional construct of simultaneous adherence to Puerto Rican and European American cultural aspects across behavioral, values, and ethnic identity domains. The B6F model of island Puerto Rican acculturation suggests that even in the absence of a migration experience, island Puerto Ricans may experience bidimensional and multifaceted acculturation.

Technical Note: Procedure for the calibration and validation of kilo-voltage cone-beam CT models.

PURPOSE: The aim of this work is to propose a general and simple procedure for the calibration and validation of kilo-voltage cone-beam CT (kV CBCT) models against experimental data. METHODS: The calibration and validation of the CT model is a two-step procedure: the source model then the detector model. The source is described by the direction dependent photon energy spectrum at each voltage while the detector is described by the pixel intensity value as a function of the direction and the energy of incident photons. The measurements for the source consist of a series of dose measurements in air performed at each voltage with varying filter thicknesses and materials in front of the x-ray tube. The measurements for the detector are acquisitions of projection images using the same filters and several tube voltages. The proposed procedure has been applied to calibrate and assess the accuracy of simple models of the source and the detector of three commercial kV CBCT units. If the CBCT system models had been calibrated differently, the current procedure would have been exclusively used to validate the models. Several high-purity attenuation filters of aluminum, copper, and silver combined with a dosimeter which is sensitive to the range of voltages of interest were used. A sensitivity analysis of the model has also been conducted for each parameter of the source and the detector models. RESULTS: Average deviations between experimental and theoretical dose values are below 1.5% after calibration for the three x-ray sources. The predicted energy deposited in the detector agrees with experimental data within 4% for all imaging systems. CONCLUSIONS: The authors developed and applied an experimental procedure to calibrate and validate any model of the source and the detector of a CBCT unit. The present protocol has been successfully applied to three x-ray imaging systems. The minimum requirements in terms of material and equipment would make its implementation suitable in most clinical environments.

'The full has never been told': building a theory of sexual health for heterosexual Black men of Caribbean descent.

Research on Black sexual health often fails to represent the heterogeneity of Black ethnic groups. For people of Caribbean descent in the USA, ethnicity is a salient cultural factor that influences definitions and experiences of sexual health. Most research on people of Caribbean descent focuses on the relatively high rate of STIs, but sexual health is defined more broadly than STI prevalence. Psychological and emotional indicators and the voice of participants are important to consider when exploring the sexual health of a minority culture. The purpose of this study was to qualitatively explore how heterosexual Black men of Caribbean descent define and understand sexual health for themselves. Eleven men who self-identified as Black, Caribbean and heterosexual participated in three focus groups and were asked to define sexual health, critique behaviours expertly identified as healthy and address what encourages and discourages sexual health in their lives. Findings point to six dimensions of sexual health for heterosexual Black men of Caribbean descent. These include: heterosexually privileged, protective, contextual, interpersonal, cultural and pleasurable dimensions. There were some notable departures from current expert definitions of sexual health. Recommendations for further theory development are provided.

A two-year prospective study on the frequency and co-occurrence of insomnia and sleep-disordered breathing symptoms in a primary care population.

OBJECTIVE: We aimed to evaluate frequency and co-occurrence of insomnia and sleep-disordered breathing (SDB) symptoms and potential co-morbidity (complex insomnia). METHODS: A prospective self-assessment was conducted for adult patients with no prior sleep issues who presented to community-based primary care clinics for nonsleep-related complaints between November 2009 and June 2012. RESULTS: A brief sleep health survey (SHS) assessed insomnia and SDB symptoms. Of 801 patients, 660 (82.4%) reported at least one insomnia symptom, and 289 (36.1%) reported an insomnia disorder (Insomnia Severity Index [ISI] >7 and self-reported daytime impairment due to insomnia). At least one SDB symptom was reported by 478 (59.7%) patients, and 177 (22.1%) reported two or more symptoms. Co-occurrence of insomnia and SDB symptoms (minimum of one symptom each of insomnia and SDB) occurred in 50.8% of the sample. Using liberal criteria to assess potential co-morbid disorders (complex insomnia), 187 (23.4%) patients reported an insomnia disorder and at least one SDB symptom. With more stringent criteria, including only those patients with moderate or severe insomnia disorders plus two SDB symptoms, 48 patients (6.0% of the sample or 16.6% of all patients with insomnia disorders) indicated potential complex insomnia. CONCLUSIONS: Co-occurrence of insomnia and SDB symptoms as well as the rate of potential complex insomnia was common among a moderately large sample of primary care patients without prior evaluations or diagnoses of sleep disorders. Clinical and research implications are discussed.

Prospective assessment of nocturnal awakenings in a case series of treatment-seeking chronic insomnia patients: a pilot study of subjective and objective causes.

BACKGROUND: The cause of nocturnal awakenings in patients with chronic insomnia is rarely researched. This study prospectively assessed the etiology of nocturnal awakenings (subjectively and objectively) among patients with insomnia at a private, community-based sleep medical center. METHODS: Twenty adult patients with chronic insomnia enrolled between April 2008 and February 2010 met diagnostic criteria for an insomnia disorder, never previously visited a sleep specialist or underwent sleep testing, and reported no classic sleep disordered breathing symptoms. Patients completed validated scales for insomnia, sleepiness, impairment, anxiety, depression, and quality of life, a qualitative interview to assess subjective reasons for awakenings, and a diagnostic sleep study to objectively assess awakenings and their precipitants. RESULTS: Subjective and objective data showed clinically meaningful insomnia, primarily sleep maintenance insomnia. The most common self-reported reasons for awakenings were: uncertain cause (50%), nightmares (45%), nocturia (35%), bedroom distractions (20%), or pain (15%). No patient identified breathing symptoms as a cause. Objectively, 531 awakenings were observed in the total sample, and 478 (90%) were preceded by sleep breathing events (apnea, hypopnea, or respiratory effort-related event). Fifty-three awakenings were caused by other factors (independent leg jerks [7], spontaneous [14], and sleep that was laboratory-induced [32]). Thirty awakenings ≥ 5 min-a duration sufficient to predispose toward an insomnia episode-were each preceded by a breathing event. CONCLUSIONS: Among patients with insomnia with no classic sleep breathing symptoms and therefore low probability of a sleep breathing disorder, most of their awakenings were precipitated by a medical condition (sleep disordered breathing), which contrasted sharply with their perceptions about their awakenings

Sexual orientation microaggressions: the experience of lesbian, gay, bisexual, and queer clients in psychotherapy.

Psychological research has shown the detrimental effects that overt heterosexism have on lesbian, gay, bisexual, and queer (LGBQ) clients and on the psychotherapeutic relationship. However, the effects of subtle forms of discrimination, specifically sexual orientation microaggressions, have on LGBQ clients and the therapeutic relationship have not been addressed. This study used qualitative methodology to explore the phenomenon of sexual orientation microaggressions with 16 self-identified LGBQ psychotherapy clients. Results of this study support the existence of sexual orientation microaggressions within the therapeutic environment and provide a descriptive account of 7 sexual orientation microaggression themes, channels of microaggression communication, and the impact microaggressions have on therapy and clients.

Patients with treatment-resistant insomnia taking nightly prescription medications for sleep: a retrospective assessment of diagnostic and treatment variables.

BACKGROUND: Some chronic insomnia patients who take nightly prescription medication achieve less than optimal results. The US Food and Drug Administration (FDA) and the American Academy of Sleep Medicine (AASM) recommend reevaluation of this type of patient to assess for potential psychiatric or medical causes to explain this "failure for insomnia to remit." METHOD: A retrospective chart review examined a consecutive series of chronic insomnia patients with persistent insomnia complaints despite current nightly use of prescription medication from May 2005 to February 2008. To assess the role of psychiatric influences on insomnia symptoms, our sample (N = 218) was divided into 2 subgroups: a group with a history of psychiatric complaints (psychiatric insomnia, n = 189) and a control group of no psychiatric complaints (insomnia, n = 29). RESULTS: The average patient reported insomnia for a decade and took prescription medication for sleep for a mean of 4.5 years. Although 100% of the sample used nightly sleep drugs, only 20% believed medication was the best solution for their condition. As evaluated by self-report and polysomnography, these patients exhibited moderately severe insomnia across most measures. Only a few differences were noted between groups. Subjective perception of insomnia severity was worse in the psychiatric insomnia group, which also reported significantly more insomnia-related interference in daily functioning, symptoms of sleep maintenance insomnia, and a trend toward greater daytime fatigue. The mean Apnea-Hypopnea Index score was 19.5 events/hour, yielding an obstructive sleep apnea diagnosis in 75% of patients per conservative AASM nosology (79% in the insomnia group and 74% in the psychiatric insomnia group, P = .22). CONCLUSIONS: In this treatment-seeking sample of patients regularly taking sleep medications, residual insomnia was widespread, and patients with psychiatric insomnia may have perceived their condition as more problematic than a control group of insomnia patients without mental health complaints. Both groups exhibited high rates of objectively diagnosed obstructive sleep apnea, a medical condition associated with pervasive sleep fragmentation. These findings support FDA and AASM guidelines to reassess chronic insomnia patients who manifest residual symptoms despite nightly use of prescription medication for sleep.

Nocturia and snoring: predictive symptoms for obstructive sleep apnea.

PURPOSE: Current screening for obstructive sleep apnea (OSA) emphasizes self-reported snoring and other breathing symptoms. Nocturia, a symptom with a precise pathophysiological link to sleep apnea, has not been assessed as a screening tool for this common disorder of sleep respiration. In a large sample of adults presenting to area sleep centers, we aimed to determine the predictive power of nocturia for OSA and compare findings with other markers of OSA commonly used to screen for this disease. METHODS: This was a retrospective chart review. A consecutive sample of 1,007 adult patients seeking treatment at two sleep centers in New Mexico completed detailed medical and sleep history questionnaires and completed diagnostic polysomnography testing. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of nocturia, snoring, high body mass index, sex, and age for OSA were determined. Hierarchical linear regression determined unique variance contribution to the apnea-hypopnea index, the objective measure of sleep apnea severity. RESULTS: The results are as follows: sensitivities--snoring, 82.6% and nocturia, 84.8%; specificities--snoring, 43.0% and nocturia, 22.4%; PPVs--snoring, 84.7% and nocturia, 80.6%; and NPVs--snoring, 39.6% and nocturia, 27.9%. With hierarchical linear regression, patient-reported nocturia frequency predicted apnea-hypopnea index (OSA severity) above and beyond body mass index, sex, age, and self-reported snoring (P<0.0001). CONCLUSIONS: Nocturia appears comparable to snoring as a screening tool for OSA in patients presenting to a sleep medical center. Research in urology and primary care clinics is needed to definitively clarify the use of nocturia as a screening instrument for obstructive sleep apnea.

A psychometric examination of multidimensional inventory of black identity (MIBI) scores.

The factor structure of the Multidimensional Inventory of Black Identity (MIBI) was assessed in a sample of 272 African American college students using confirmatory and exploratory factor analyses. The fit indices from the confirmatory analyses did not support the seven-factor first-order model or two alternative higher-order models suggested by the developers, but yielded numerous recommendations for modifications. A post hoc exploratory factor analysis indicated that MIBI items were best represented by a five-factor structure.

Diverticulo de Meckel / Meckel's diverticulum

El divertículo de Meckel representa la alteración congénita más frecuente del intestino delgado, con una incidencia en la población general de más o menos el 2%. Explicada su presencia por persistencia de la parte proximal del conducto vitelino, puede estar asociado con numerosos procesos patológicos de importancia, lo cual apoya su tratamiento quirúrgico siempre que sea reconocida su presencia y lo coloca como diagnóstico diferencial a tomar en cuenta en procesos abdominales agudos. Se presenta un análisis en el Hospital General del Oeste "Dr. José Gregorio Hernández" en un período de 15 años (1975-1990), con una incidencia del divertículo de Meckel de aproximadamente 0,02%

TBC abdominal: gran simuladora. Hospital General del Oeste "Dr. J.E. Hernández", Caracas / Abdominal TBC: dissembler grand

La TBC Abdominal constituye una entidad de difícil diagnóstico preoperatorio debido a que su presentación puede confundir con otras entidades que van desde la apendicitis aguda hasta neoplasias benignas y malignas de tracto digestivo o ginecológico. Se presentan dos casos de TBC Abdominal tratados en el Hospital General del Oeste "Dr. J.G. Hernández" entre los años 1985 y 1989, y en quienes el diagnóstico de TBC se hizo después del estudio histopatológico de las piezas quirúrgicas, ya que la clínica y los métodos complementarios indicaban otras entidades nosológicas
