Akt (protein kinase B) signaling is frequently activated in diverse cancers. Akt inhibitors such as perifosine and MK-2206 have been evaluated as potential cancer chemotherapeutics. Although both drugs are generally well tolerated, among their most common side-effects vomiting is a major concern. Here we investigated whether these Akt inhibitors evoke emesis in the least shrew model of vomiting. Indeed, both perifosine and MK-2206 induced vomiting with maximal efficacies of 90% at 50 mg/kg (i.p.) and 100% at 10 mg/kg (i.p.), respectively. MK-2206 (10 mg/kg, i.p.) increased c-Fos immunoreactivity both centrally in the shrew brainstem dorsal vagal complex (DVC) emetic nuclei, and peripherally in the jejunum. MK-2206 also evoked phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2) in both the DVC emetic nuclei and the enteric nervous system in the jejunum. The ERK1/2 inhibitor U0126 suppressed MK-2206-induced emesis dose-dependently. We then evaluated the suppressive efficacy of diverse antiemetics against MK-2206-evoked vomiting including antagonists/inhibitors of the L-type Ca2+ channel (nifedipine at 2.5 mg/kg, subcutaneously (s.c.)); glycogen synthase kinase 3 (GSK-3) (AR-A014418 at 10 mg/kg and SB216763 at 0.25 mg/kg, i.p.); 5-hydroxytryptamine 5-HT3 receptor (palonosetron at 0.5 mg/kg, s.c.); substance P neurokinin NK1 receptor (netupitant at 10 mg/kg, i.p.) and dopamine D2/3 receptor (sulpride at 8 mg/kg, s.c.). All tested antagonists/blockers attenuated emetic parameters to varying degrees. In sum, this is the first study to demonstrate how pharmacological inhibition of Akt evokes vomiting via both central and peripheral mechanisms, a process which involves multiple emetic receptors.In patients with obstructive jaundice, the cardiovascular system exhibits hypotension and vascular hyporeactivity. Most norepinephrine is taken up through the neuronal norepinephrine transporter (NET), which is implicated in cardiovascular diseases. A previous study demonstrated that pharmacological NET inhibition could increase resting blood pressure. However, the role of NETs in vascular hyporeactivity induced by obstructive jaundice is poorly understood. This study used the NET inhibitor nisoxetine and a rat model of bile duct ligation (BDL) to investigate whether NET is associated with BDL-induced vascular hyporeactivity. Rats were injected with nisoxetine via the tail vein for 7 consecutive days after BDL. Samples of the superior cervical sympathetic ganglion (SCG) and thoracic aortic rings were processed for investigations. Our results showed that NET expression in the SCG was significantly increased after BDL. Nisoxetine prevented the augmentation of NET expression, increased α1-adrenoceptor activation, and enhanced the weakened contractile responses of thoracic aortic rings after BDL. CRCD2 purchase Our study demonstrates that nisoxetine plays a protective role in BDL-induced vascular hyporeactivity through increased α1-adrenoceptor activation in rats.Optimal strategies for integration of clinical practice guidelines into electronic medical records and its impact on processes of care and clinical outcomes in diabetic patients are not well understood. A systematic review of CINAHL, MEDLINE, PubMed, and Cochrane Library databases in August 2016, November 2017, and June 2020 was conducted. Studies investigating integration of diabetes guidelines into ambulatory care electronic medical records reporting quantitative results were included. After screening 15,783 records, 21 articles were included. Lipid and blood pressure control consistently improved with guideline integration, but A1c control remained equivocal. Electronic guideline integration improved microvascular complication screening, vaccination, and documentation of cardiovascular risk factors, while medication prescription and blood pressure, lipid, and A1c documentation did not improve. Studies employing a combination of electronic record intervention strategies were associated with improvement in monitoring and attainment of guideline and screening targets. link2 Thus, strategies employing combinations of interventions to incorporate guidelines into electronic records may improve processes of care and some clinical outcomes.The diagnosis and treatment of seizures and epilepsy is a common task of the physician. Approximately 1 in 10 people will have a seizure during their lifetime. Epilepsy is the tendency to have unprovoked seizures. Epilepsy is the fourth most common neurological disorder and affects 1 in 26 people in the United States and 65 million people worldwide. Evaluation of a patient presenting with a seizure involves excluding an underlying neurologic or medical condition, classifying the seizure type and determining if the patient has epilepsy. Proper treatment requires accurate diagnosis of the epilepsy type and syndrome and use of a medication that is effective and without adverse effects. Most patients can achieve complete seizure control with medication, but if medication is unsuccessful, surgical treatment can be an option. Special situations in the care of people with epilepsy include status epilepticus, women with epilepsy, the older adult, and safety issues.
Despite national guidelines emphasizing the importance of vaccination or documenting immunity to hepatitis A virus and hepatitis B virus for patients with chronic liver disease, the success of adhering to these recommendations is suboptimal. We aim to evaluate the prevalence of vaccination or documented reactivity to hepatitis A antibody and hepatitis B surface antibody among US adults with chronic liver disease.
Using 2011-2018 National Health and Nutritional Examination Survey data, adults with nonalcoholic fatty liver disease, alcoholic liver disease, hepatitis B, and hepatitis C were evaluated to determine prevalence of vaccination (self-reported completion) and hepatitis A antibody reactivity or hepatitis B surface antibody reactivity.
Overall prevalence of vaccination or hepatitis A antibody reactivity was lowest among individuals with nonalcoholic fatty liver disease (60.8%; 95% confidence interval [CI], 57.9-63.6) and alcoholic liver disease (61.8%; 95% CI, 59.0-64.6), and highest among individu A or hepatitis B infections.
To explore the experiences of women who received life-limiting fetal diagnoses during pregnancy and support from a perinatal palliative care program.
Descriptive qualitative.
The perinatal palliative care program is part of a not-for-profit system of 24 hospitals serving the U.S. Intermountain West region.
A convenience sample of 12 women who experienced pregnancies with life-limiting fetal diagnoses and received care from a perinatal palliative care program.
Women chose to participate from mailed invitations or responded to a post on private social media and then completed semistructured interviews about their experiences surrounding the fetal diagnoses and support froma perinatal palliative care program. Interviews were approximately 40 minutes in length and were conducted over the phone, recorded, and then transcribed. We performed content analysis by coding, forming categories of similar coded data, and constructing themes by recontextualizing categories through iterative, team-based meetings.
We identified four themes from the data Importance of Memorabilia to Cope With the Death and Documentation of Pregnancy, Acceptance of Death as Part of the Pregnancy Experience, Continued Life Without a Child, and Importance of Empathy Throughout the Process.
The themes support the existing research findings about the needs of pregnant women as they cope with difficult situations. Our findings show the necessity and importance of perinatal palliative care programs.

To describe the experiences and perceptions of Mississippi maternity nurses in hospitals that gained Baby-Friendly designation, including perceived barriers and facilitators to implementation of the Baby-Friendly Hospital Initiative.
Descriptive qualitative study using thematic analysis of focus group data.
Maternity care services of five Baby-Friendly-designated hospitals in Mississippi.
Twenty-two maternity nurses.
We conducted 90-minute in-person focus groups in which participants described their hospitals' Baby-Friendly experiences. We analyzed focus group transcripts thematically to describe the facilitators and barriers to implementation of the Baby-Friendly initiative.
We identified five main themes The Change Required for BFHI Was Hard, Nurses Felt Empowered by Taking Leadership Roles, Patient Education Was Pivotal to Practice Implementation, Nurses Felt Challenged by Unintended Consequences, and Attitudes Changed From Negative to Positive Over the Course of Adoption.
Participants from hospitals throughout Mississippi shared similar experiences and cited common facilitators and barriers to achieving Baby-Friendly designation. Participants described the overall process of Baby-Friendly designation as challenging but worthwhile because of the resulting improvements in maternity care, nurses' knowledge, and health outcomes for women and their newborns. Nurses at other hospitals that seek to obtain designation can learn from these experiences to make their own transitions easier.

Epigenetic regulation-control of gene action through chemical and structural changes of chromatin-provides a platform to integrate multiple extracellular inputs and prepares the cellular genome for appropriate gene expression responses. Coregulation by polycomb repressive complex 2-mediated trimethylation of lysine 27 on histone 3 and DNA methylation has emerged as one of the most influential epigenetic controls in colorectal cancer and many other diseases, but molecular details remain inadequate. Here we review the molecular interplay of these epigenetic features in relation to gastrointestinal development, homeostasis, and disease biology. We discuss other epigenetic mechanisms pertinent to the balance of trimethylation of lysine 27 on histone 3 and DNA methylation and their actions in gastrointestinal cancers. We also review the current molecular understanding of chromatin control in the pathogenesis of inflammatory bowel diseases.
The aim of this study was to investigate the relationship between the subcomponents of burnout and year of training among radiology residents.
In this cross-sectional analysis, the Maslach Burnout Inventory Human Services Survey for Medical Personnel (MBI-HSS [MP]) was distributed to eligible United States (US) radiology residents. Primary outcomes included the MBI-HSS (MP) subcomponents emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA). Multivariate analysis of variance, tests of between-subjects effects, and Tukey post hoc analysis with 95% confidence interval were conducted.
A total of 770 of 2,823 residents (27.3%) responded, with 488 of 770 completing the MBI-HSS (MP). There was a statistically significant difference in subcomponent scores between cohorts based on year of training (P < .005) and a statistically significant effect between year of training and EE (P < .05) and DP (P < .005), but not PA. Third-year (R3) residents reported a higher frequency of EE than first-year (R1) residents and a higher frequency of DP than R1 and second-year (R2) residents.
