Incarceration history and opioid use among adults living with HIV and chronic pain: a secondary analysis of a prospective cohort study.

Background: Adults living with HIV have disproportionately high chronic pain, prescription opioid use, history of substance use, and incarceration. While incarceration can have long-lasting health impacts, prior studies have not examined whether distant (>1 year prior) incarceration is associated with opioid use for chronic pain, or with opioid misuse or opioid use disorder among people living with HIV and chronic pain.

Methods: We conducted a secondary analysis of a prospective cohort study of adults living with HIV and chronic pain.

Optical Genome Mapping as a New Tool to Overcome Conventional Cytogenetics Limitations in Patients with Bone Marrow Failure.

Cytogenetic studies are essential in the diagnosis and follow up of patients with bone marrow failure syndromes (BMFSs), but obtaining good quality results is often challenging due to hypocellularity. Optical Genome Mapping (OGM), a novel technology capable of detecting most types chromosomal structural variants (SVs) at high resolution, is being increasingly used in many settings, including hematologic malignancies. Herein, we compared conventional cytogenetic techniques to OGM in 20 patients with diverse BMFSs.

Trajectories of Opioid Misuse and Opioid Use Disorder Among Adults With Chronic Pain and HIV: An Observational Study.

Objectives: In a longitudinal cohort of patients with HIV and chronic pain, we sought to (1) identify trajectories of opioid misuse and opioid use disorder (OUD) symptoms, and to (2) determine whether prescription opioid dose was associated with symptom trajectories.

Methods: We leveraged an existing 12-month longitudinal observational study, Project PIMENTO, of persons living with HIV and chronic pain who received care at a hospital system in the Bronx, New York. A quota sampling strategy was used to ensure variability of prescribed opioid use in the recruited sample.

Distribution and molecular evolution of the anti-CRISPR family AcrIF7.

Anti-clustered regularly interspaced short palindromic repeats (CRISPRs) are proteins capable of blocking CRISPR-Cas systems and typically their genes are located on mobile genetic elements. Since their discovery, numerous anti-CRISPR families have been identified. However, little is known about the distribution and sequence diversity of members within a family, nor how these traits influence the anti-CRISPR's function and evolution.

Imaging spatiotemporal translation regulation in vivo.

Translation is regulated spatiotemporally to direct protein synthesis when and where it is needed. RNA localization and local translation have been observed in various subcellular compartments, allowing cells to rapidly and finely adjust their proteome post-transcriptionally. Local translation on membrane-bound organelles is important to efficiently synthesize proteins targeted to the organelles.

A two-track model for the spatiotemporal coordination of bacterial septal cell wall synthesis revealed by single-molecule imaging of FtsW.

Synthesis of septal peptidoglycan (sPG) is crucial for bacterial cell division. FtsW, an indispensable component of the cell division machinery in all walled bacterial species, was recently identified in vitro as a peptidoglycan glycosyltransferase (PGTase). Despite its importance, the septal PGTase activity of FtsW has not been demonstrated in vivo.

An Open-Label Pilot Study of Duloxetine in Patients With Irritable Bowel Syndrome and Comorbid Major Depressive Disorder.

Major depressive disorder (MDD) and irritable bowel syndrome (IBS) frequently co-occur, yet treating their comorbid presentation is challenging. Low-dose tricyclic antidepressants are efficacious for IBS, but higher doses to treat depressive symptoms present tolerability problems, whereas selective serotonin reuptake inhibitors are more tolerable but show inconsistent efficacy for IBS. If efficacious, serotonin-norepinephrine reuptake inhibitors like duloxetine would provide a useful alternative.

Toward a cultural adaptation of pharmacotherapy: Latino views of depression and antidepressant therapy.

Relative to non-Latino Whites, Latinos in the United States with major depressive disorder (MDD) show low engagement in antidepressant therapy, whether engagement is defined as pharmacotherapy access, medication initiation, pill-taking, or treatment retention. One potential reason for this disparity in depression care is the low cultural congruence of pharmacotherapy for this population. To examine Latinos' views of depression and antidepressant therapy, we conducted qualitative interviews with 30 Latino outpatients initiating antidepressants prior to their first treatment visit using the semistructured Treatment Adherence and Retention Questionnaire.

Tree mineral nutrition is deteriorating in Europe.

The response of forest ecosystems to increased atmospheric CO2 is constrained by nutrient availability. It is thus crucial to account for nutrient limitation when studying the forest response to climate change. The objectives of this study were to describe the nutritional status of the main European tree species, to identify growth-limiting nutrients and to assess changes in tree nutrition during the past two decades.

Fatalism or destiny? A qualitative study and interpretative framework on Dominican women's breast cancer beliefs.

Background: A growing literature on Latino's beliefs about cancer focuses on the concept of fatalismo (fatalism), despite numerous conceptual ambiguities concerning its meaning, definition, and measurement. This study explored Latina women's views on breast cancer and screening within a cultural framework of destino ("destiny"), or the notion that both personal agency and external forces can influence health and life events.

Methods: Semi-structured interviews were conducted with 25 Latinas from the Dominican Republic aged 40 or over.

Commentary: fatalismo reconsidered: a cautionary note for health-related research and practice with Latino populations.

Over recent years, interest has grown in studying whether fatalismo (fatalism) deters Latinos from engaging in various health promotion and disease detection behaviors, especially with regard to cancer screening. This commentary presents problematic issues posed by the concept of fatalism, focusing on research on Latinos and cancer screening. We discuss key findings in the literature, analyze methodologic and conceptual problems, and highlight structural contexts and other barriers to health care as critical to the fatalism concept.

[Risk factors for Giardia lamblia infection in children in daycare centers in Havana, Cuba].

We conducted a longitudinal study on giardiasis in three daycare centers in Havana City for a period of 18 months and described a group of children with a "predisposition" or tendency towards re-infection with Giardia lamblia. This group was found to be more frequently associated with clinical symptoms such as diarrhea. A case-control study was designed to determine whether socioeconomic factors and hygiene were associated with this phenomenon.
