Parents who were abused as children are at increased risk for perpetuating maladaptive parenting practices, yet the mechanisms underlying this relationship remain unclear. This study prospectively examined maternal distress (a latent variable consisting of depressive symptoms and daily stress) and family violence as potential mediators in the intergenerational transmission of abusive (i.e., psychologically aggressive and physically assaultive) parenting. Participants included (N = 768) mother-child dyads identified as being at-risk for family violence and maltreatment prior to children's age four. More maternal childhood abuse was associated with more distress and increased risk for family violence exposure in adulthood. However, only maternal distress mediated the association between mothers' history of abuse and their use of abusive parenting strategies. This study provides critical information about ecological mechanisms underlying the intergenerational transmission of abusive parenting and suggests the importance of targeting depression and stress management among mothers with abuse histories to curtail the cycle of violence.Many foodstuffs are extremely susceptible to contamination with aflatoxins, in which aflatoxin B1 is highly toxic and carcinogenic. selleck products Therefore, it is crucial to develop a rapid and effective analytical method for detecting and monitoring aflatoxin B1 in food. Herein, a surface-enhanced Raman spectroscopic (SERS) method combined with QuEChERS (quick, easy, cheap-effective, rugged, safe) sample pretreatment technique was used to detect aflatoxin B1. Sample preparation was optimized into a one-step extraction method using an Au nanoparticle-based solution (Au sol) as the SERS detection substrate. An affordable portable Raman spectrometer was then used for rapid, label-free, quantitative detection of aflatoxin B1 levels in foodstuffs. This method showed a good linear log relationship between the Raman signal intensity of aflatoxin B1 in the 1-1000 µg L-1 concentration range with a limit of detection of 0.85 µg kg-1 and a correlation coefficient of 0.9836. Rapid aflatoxin B1 detection times of ∼10 min for wheat, corn, and protein feed powder samples were also achieved. This method has high sensitivity, strong specificity, excellent stability, is simple to use, economical, and is suitable for on-site detection, with good prospects for practical application in the field of food safety.
Prospective lumbar radiograph analysis.
To compare changes in lumbar lordosis in standing flexion versus seated lateral radiographs.
Standing lateral, standing flexion, and seated lateral X-rays of the lumbar spine were obtained in patients presenting with low back pain. Trauma, tumor, and revision cases were excluded. Changes in global lumbar as well as segmental lordosis were measured in each position.
Seventy adult patients were reviewed. Overall, the greatest changes in lordosis were seen at L4-S1 in both the seated and flexion X-rays (12.5° and 6.3°, respectively). Greater kyphosis was seen in seated versus flexion X-rays (21.6° vs 15.8°); changes in lordosis from L1-L3 were similar in both positions, with little change seen at these levels (approximately 5° to 7°). On subgroup analysis, these differences were magnified in analyzing only patients that moved at least 20° globally, and there were no significant differences between sitting and flexion in "stiff" patients that moved less than 20° globally.
Greater lumbar kyphosis was seen in the seated position compared to standing flexion, especially from L4-S1. Given these results we suggest the use of seated lateral X-rays to dynamically assess the lumbar spine. These findings may also guide future research into the mechanism and clinical relevance of a stiff versus mobile lumbar spine, as well as into the sensitivity of seated X-rays in detecting instability.

In 2018, the country's HIV prevalence was 2% with an estimated 2200 AIDS-related deaths. Using 2016-2017 Demographic and Health Survey (DHS) data, Haitian men's self-reported ever-having HIV testing was analyzed with a focus on their regions of residence. Only 34% of the men reported ever-having HIV testing. Men who lived in Northern region (aOR1.59, 95%CI1.23-2.05), and Southern region (aOR1.26, 95%CI1.04-1.53) had higher odds of ever-having HIV testing compared to men residing in Central region. Further research should prioritize targeted health promotion for engaging Haitian men who are younger, poorer, with low-level of education and single as well as those who reside in regions where HIV testing is not easily accessible. Haitian men who have not had an HIV test must first be identified and demographic-specific interventions and programming should be used to increase HIV testing among this population.
Retrospective observational study.
The aim of the present study was to evaluate the role of lumbar magnetic resonance imaging (MRI) in the diagnostic algorithm of sacral insufficiency fractures (SIF). The primary objective was to compare the sensitivity in fracture detection and correct fracture classification according to MRI and computed tomography (CT). The secondary objective was to identify differences of additional pathologies found in MRI of the lumbar spine and the pelvis and their rates.
A total of 943 patients (from 2010 to 2017) with fracture of the pelvic ring were screened. All patients without high-energy trauma and radiologic diagnostics consisting of X-ray, CT, and MRI of the pelvis or the lumbar spine including the sacrum were included. Differences in fracture detection and description in the various radiologic procedures were evaluated. Detection rates of additional pathologies in MRI of the pelvis and lumbar spine were recorded.
A total of 77 subjects were included. The sensitivities for SIF were 14% in X-ray and 88% in CT, and all fractures were detected in MRI. MRI showed a more complex fracture pattern compared with CT in 65% of the cases. Additional pathologies were seen in MRI of the lumbar spine (51%) and that of the pelvis (18%).
We suggest performing MRI of the lumbar spine including the sacrum with coronal STIR (short tau inversion recovery) sequence for elderly patients with suddenly increasing low back pain at an early stage. This procedure might improve fracture detection, classification, and recognition of concomitant pathologies.

Canagliflozin is a US FDA-approved SGLT2 inhibitor that has demonstrated CV and renal outcome benefits in large scale placebo-controlled randomized trials of patients with Type 2 diabetes mellitus and elevated CV risk. Canagliflozin use may also be associated with serious and nonserious adverse effects requiring ongoing monitoring in patients initiated on this medication. This paper provides a detailed overview of canagliflozin including its pharmacologic profile, clinical efficacy and safety data, with discussion of both clinical trial results, as well as real-world evidence.Nowadays, the presence of antibiotic residues in foods with animal origin has become an important challenge for public health authorities in many countries. Antibiotic residues are associated with several health problems in the human body such as acute allergic or toxic reactions, chronic toxic effects, and disturption of the natural balance of intestinal microflora as well as the emergence of antimicrobial resistance pathogenic bacteria. In order to determine the trace levels of antibiotics in the foodstuff, the development of rapid, sensitive and accurate analytical methods is necessary. Besides the great advances in the development of analytical instruments in recent years, sample preparation remains a critical step of any analytical procedure. Since food samples have complex and heterogeneous matrices, the sample preparation method can affect the accuracy, precision and overall performance of an analytical technique. Liquid-liquid extraction (LLE) is one of the most commonly used techniques for sample preparation which allows the selective concentration of target analytes in the aqueous samples. The aim of this study was to provide an updated overview of the recent trends and development in LLE techniques over the past 5 years. Different variations of this method such as hollow fiber liquid-phase microextraction, dispersive liquid-liquid microextraction, salting-out LLE, and aqueous two-phase system extraction are given in the present study. This review is focused on recent innovations and modifications in the LLE procedure which try to improve the efficiency and safety of this technique.
Basic science.
To compare the effects of a neuropeptide Y1 receptor antagonist (NPY-1RA) to estrogen on maintaining vertebral bone microarchitecture and disc height in a rat model of menopause.
This study was an institutional animal care approved randomized control study with 104 ovariectomized rats and 32 intact control animals. Comparison of disc height, trabecular bone, body weights, circulating levels of NPY and estrogen, and distribution of Y1 receptors in the intervertebral disc in an established rodent osteoporotic model were made at baseline and after 2, 4, and 8 weeks after receiving either an implant containing estrogen or an antagonist to the neuropeptide Y1 receptor. Data was compared statistically using One-way analysis of variance.
Circulating levels of estrogen increased and NPY decreased following estrogen replacement, with values comparable to ovary-intact animals. NPY-1RA-treated animals had low estrogen and high NPY circulating levels and were similar to ovariectomized control rats. Both NPY-1RA and estrogen administration were able reduce, menopause associated weight gain. NPY-1RA appeared to restore bone formation and maintain disc height, while estrogen replacement prevented further bone loss.
NPY-1RA in osteoporotic rats activates osteoblast production of bone and decreased marrow and body fat more effectively than estrogen replacement when delivered in similar concentrations. Annulus cells had NPY receptors, which may play a role in disc nutrition, extracellular matrix production, and pain signaling cascades.
