Here, substance misuse captures a pattern of substance use problems over time that may be indicative of a substance use disorder. These terms should be distinguished from studies investigating the frequency (how often) and quantity (how much) of a substance is being used where risky substance use is appropriate for cross-sectional studies and heavy substance use is appropriate for longitudinal studies. Conclusion This framework is intended to describe the phenomena being investigated (i.e., the variable) and not the person or people experiencing a substance use problem. We should continue the dialogue of semantics in science realizing that our choice of words has important "real world" ramifications for the populations we serve.Some adipocytes are produced from bone marrow hematopoietic stem cells. In vitro studies previously indicated that these bone marrow-derived adipocytes (BMDAs) were generated from adipose tissue macrophage (ATM) that lose their hematopoietic markers and acquire mesenchymal markers prior to terminal adipogenic differentiation. Here we interrogated whether this hematopoietic-to-mesenchymal transition drives BMDA production In vitro. We generated transgenic mice in which the lysozyme gene promoter (LysM) indelibly labeled ATM with green fluorescent protein (GFP). We discovered that adipose stroma contained a population of LysM-positive myeloid cells that simultaneously expressed hematopoietic/myeloid markers (CD45 and CD11b), and mesenchymal markers (CD29, PDGFRa and Sca-1) typically found on conventional adipocyte progenitors. These cells were capable of adipogenic differentiation In vitro and In vitro, while other stromal populations deficient in PDGFRa and Sca-1 were non-adipogenic. BMDAs and conventional adipocytes expressed common fat cell markers but exhibited little or no expression of hematopoietic and mesenchymal progenitor cell markers. The data indicate that BMDAs are produced from ATM simultaneously expressing hematopoietic and mesenchymal markers rather than via a stepwise hematopoietic-to-mesenchymal transition. Because BMDA production is stimulated by high fat feeding, their production from hematopoietic progenitors may maintain adipocyte production when conventional adipocyte precursors are diminished.An isolated defect in the lateral orbital wall is an uncommon occurrence, although cases of orbital floor, roof, and medial wall spontaneous dehiscence have been described in the literature. Here, we describe a lateral orbital wall defect in a patient with thyroid eye disease - which may be related to bony remodeling or may represent a rare congenital anomaly. Computed tomography (CT) prior to decompression surgery revealed a defect in the left lateral orbital wall. At the time of orbital decompression, prolapse of buccal fat into the orbit was noted once the subperiosteal plane was entered along the lateral orbital wall in the area of this bony defect. Literature review revealed only a few previous reports of lateral wall abnormalities, including two involving the inferior orbital fissure; one other case was associated with Down syndrome, and other reports consist of sphenoid hypoplasia associated with neurofibromatosis.
To determine whether abdominal (open)
laparoscopic myomectomy affects the obstetrical outcomes of subsequent pregnancies.

A retrospective cohort study was conducted at a tertiary university medical center. The study population included women who had a documented birth following a myomectomy at our institution between the years 1997 and 2018. JAK inhibitor The obstetrical characteristics and immediate perinatal outcomes of the subsequent pregnancy following open
laparoscopic myomectomy were collected and compared. Data were retrieved from patients' medical records
the institutional computerized database. Cases that lacked detailed surgery and delivery reports were excluded. Data were analyzed using a chi-square test for categorical variables and one-way ANOVA for continuous variables. A
-value <.05 was considered statistically significant.

During the study period, 57 women met the inclusion criteria, of whom 66.6% (38/57) had an open and 33.3% (19/57) had a laparoscopic myomectomy. Women who underwent an open myomectomy had a higher rate of cesarean birth than those in the laparoscopic group (89.5
42.1%,
 < .001). No cases of severe maternal or perinatal complications, uterine ruptures, or placental abruptions were identified in either study group. No other significant differences were noted between the two types of myomectomy.

Open myomectomy is associated with a higher rate of cesarean delivery than laparoscopic. No severe adverse maternal or neonatal outcomes were detected in either study group.

This recurrent issue in recent memory research bears relevance to expert witness work in the courtroom. In this review, we will argue that several crucial aspects of EMDR may be detrimental to memory. First, research has shown that eye movements undermine the quality and quantity of memory. Specifically, eye movements have been shown to decrease the vividness and emotionality of autobiographical experiences and amplify spontaneous false memory levels. Second, a sizeable proportion of EMDR practitioners endorse the controversial idea of repressed memories and discuss the topic of repressed memory in therapy. Third, in the Dutch EMDR protocol, patients are instructed to select the target image by using flawed metaphors of memory (e.g., memory works as a video). Such instructions may create demand characteristics to the effect that people over-interpret imagery during therapy as veridical memories. Collectively, the corpus of research suggests that several components of EMDR therapy (i.e., performing eye movements, therapist beliefs and therapeutic instructions) may undermine the accuracy of memory, which can be risky if patients, later on, serve as witnesses in legal proceedings.Pediatric sepsis is a common problem worldwide and is associated with significant morbidity and mortality. Best practice recommendations have been published by both the American College of Critical Care Medicine and the Surviving Sepsis Campaign to guide the recognition and treatment of pediatric sepsis. However, implementation of these recommendations can be challenging due to the complexity of the care required and intensity of resources needed to successfully implement programs. This paper outlines the experience with implementation of a pediatric sepsis quality improvement program at Primary Children's Hospital, a free-standing, quaternary care children's hospital in Salt Lake City. The hospital has implemented sepsis projects across multiple care settings. Challenges, lessons learned, and suggestions for implementation are described.PLAIN LANGUAGE SUMMARYSepsis is a life-threatening condition that results from an inappropriate response to an infection by the body's immune system. All children are potentially susceptible to sepsis, with nearly 8,000 children dying from the disease in the US each year. Sepsis is a complicated disease, and several international groups have published guidelines to help hospital teams treat children with sepsis appropriately. However, because recognizing and treating sepsis in children is challenging and takes a coordinated effort from many different types of healthcare team members, following the international sepsis guidelines effectively can be difficult and resource intensive. This paper describes how one children's hospital (Primary Children's Hospital in Salt Lake City, Utah) approached the challenge of implementing pediatric sepsis guidelines, some lessons learned from their experience, and suggestions for others interested in implementing sepsis guidelines for children.AimTo describe the clinical presentation and demographic distribution of retinitis pigmentosa in patients presenting to a multi-tier ophthalmology hospital network in India and implications for potential treatments.DesignCross-sectional hospital-based study.MethodsThis study included 2,541,810 patients presenting between March 2012 and October 2020. Patients with a clinical diagnosis of retinitis pigmentosa in at least one eye were included as cases. The data were collected using an electronic medical record system.ResultsOverall, 15,062 (0.59%) new patients were diagnosed with retinitis pigmentosa and were included for analysis. The median age was 35 (IQR 21-49) years and adult age (84.56%) presented more often. The most common presenting age group was between 21 and 30 years (20%). Majority of patients were male (61.68%) and had bilateral (96.39%) affliction. There was a family history in a tenth of the patients (10.46%) and a history of consanguinity in a minority (5.53%). The majority of the eyes had mild or no central visual acuity impairment of less then 20/70 (34.25%) followed by blindness less then 20/400 to 20/1200 (21.26%). The predominant retinal signs included disc pallor (76.43%), attenuated arterioles (82.61%) and bony spicule pigmentation (90.15%), and almost all had retinal pigmentary changes. A minority of the eyes underwent a surgical procedure (4.96%).ConclusionRetinitis pigmentosa is commonly bilateral and predominantly affects males. Most patients present in the third decade of life with severe visual acuity impairment. More than half of the eyes from our study are potential candidates for newer therapies. These results have implications for upcoming treatment choices and planning.
Renal sympathetic denervation (RDN) is an alternative treatment for resistant hypertension (RH). This study aims to compare ablation effects using three radiofrequency applicators (i.e., balloon-based four electrodes, spiral and monopolar devices).

An idealized three-dimensional model of the renal artery was established using COMSOL Multiphysics to mimic radiofrequency ablation (RFA). Radiofrequency (RF) energy was delivered to the tissue at the same simulation settings, i.e., 4, 6, and 8 W for 60 s, using the three abovementioned RF applicators. The temperature distribution in the tissue was calculated using the coupled electrical-thermal-fluid finite element method. Lesion borders were defined using 50 °C isotherms. The maximum lesion depth, width, area, and circumferential coverage rate were compared among the three applicators at a blood flow of 0.4 m/s. Monopolar RF ablations in a renal artery phantom model were performed to validate the reliability of the simulation method.

The balloon-based systeal catheter ablation yields the smallest lesion size and a significant change in flow velocity in the flow field, its coverage rate is larger than that of monopolar RDN; compared with balloon-based RDN, it did not obstruct most of the blood flow.
In terms of lesion size, balloon-based RDN appears to be the best option for the treatment of RH. However, the change in flow velocity in the arterial flow field suggests that its hemodynamic changes must be prioritized for investigating its safety. Although spiral catheter ablation yields the smallest lesion size and a significant change in flow velocity in the flow field, its coverage rate is larger than that of monopolar RDN; compared with balloon-based RDN, it did not obstruct most of the blood flow.
