RESUMEN

Pruritus is a common dermatologic complaint during pregnancy. Pruritus is reported by 23-38% of women during pregnancy, and 2% report severe pruritus. In addition to interfering with sleep and reducing overall quality of life during pregnancy, pruritus may be the first, or only, symptom of an underlying disorder that may impact maternal and fetal outcomes. It is therefore critical for all providers caring for pregnant women to be familiar with pregnancy-specific and non-specific conditions associated with pruritus to most effectively manage this unique population. In this review, we discuss clinical classification of pruritus, a practical approach to the differential diagnosis of pruritus in pregnancy, and focus on updates in the clinical features, diagnosis, management, and prognosis of pregnancy-specific causes of pruritus.

RESUMEN

BACKGROUND: Early readmissions in acute pancreatitis (AP) are common. The impact of opiate prescriptions on readmissions is unknown. AIMS: To determine whether the prescription of opiates at hospital discharge and the dose prescribed are associated with early readmissions in AP. METHODS: Direct admissions from the Emergency Department (ED) for AP from September 1, 2013, to August 31, 2016 were identified. Opiate prescription was defined as a new prescription at discharge in an opiate-naïve patient. Early readmission was ED visit or hospitalization within 30 days for an AP-related reason. Multivariable logistic regression was performed, adjusted for age, Charlson Comorbidity Index, pancreatic necrosis, baseline opiate use, non-opiate analgesics, and pain score at discharge. RESULTS: A total of 318 AP patients were identified; the overall early readmission rate was 18%. One hundred and twenty-one (38%) were prescribed opiates at discharge, and 22% had an early readmission. One hundred and ninety-seven (62%) were not prescribed opiates, and 16% had an early readmission. Median opiate dose was 48 mg (24-h morphine equivalents). On multivariable analysis, neither the prescription of opiates (OR 1.2, 95% CI 0.6-2.4, p = 0.55) nor the dose of opiates (OR 0.99, 95% CI 0.99-1.00, p = 0.39) was associated with early readmission. In subset analysis of patients discharged with an opiate prescription, those on opiates at baseline were significantly more likely to have an early readmission (OR 4.19, 95% CI 1.04-16.94, p = 0.04). CONCLUSIONS: In AP patients, neither prescription of opiates at discharge nor prescribed dose was associated with early readmission. Patients on opiates at baseline discharged with an opiate prescription were more likely to have an early readmission.

RESUMEN

Recent passage of the Massachusetts law, An Act Relative to Substance Use, Treatment, Education, and Prevention, represents an admirable public health approach to substance use disorder (SUD), a stigmatized chronic disease that affects some of society's most vulnerable people. With its seven-day supply limit on first-time opioid prescriptions, this legislation takes an unusual approach to state government involvement in health care. By intervening in individual physicians' practices, state legislators have entered a space traditionally reserved for clinical teams. The seven-day supply limit and the process through which it was developed highlight competing priorities and dialogue between physicians and legislators, limits of physician self-regulation, and standards of evidence in policy making and health care. Addressing these issues requires both physicians and legislators to recognize and fulfill new responsibilities in order to better assist the populations they serve.

RESUMEN

Drugs, notably SSRIs, that elevate brain extracellular 5-HT (5-HTExt) are antidepressants. Unfortunately, most patients fail to remit. Multipronged clinical evidence suggests that elevating 5-HTExt beyond the SSRI effect enhances antidepressant efficacy, but previous such drug strategies had prohibitive limitations. In humans, adjunct treatment with the 5-HT precursor 5-hydroxytryptophan (5-HTP) elevates 5-HTExt beyond the SSRI effect. Small pilot trials suggest that adjunct 5-HTP can confer antidepressant response in treatment-resistant depression (TRD). However, sustained, stable 5-HTExt elevation is required for antidepressant effect; therefore, the rapid absorption and elimination of standard 5-HTP immediate release (IR) likely curtail 5-HTP IR's antidepressant potential. Slow-release (SR) drug delivery can crucially improve efficacy and safety of rapidly absorbed and eliminated compounds. Here we tested in mice the hypothesis that SR delivery will substantially improve 5-HTP's drug properties, by minimizing adverse effects and securing sustained 5-HTExt elevation beyond the SSRI effect. We modeled 5-HTP SR with minipumps, 5-HTP IR with injections, and chronic SSRI with dietary fluoxetine. We tested adjunct 5-HTP SR in wild-type mice and in mice with low brain 5-HT owing to expression of a mutant form of the brain 5-HT synthesis enzyme, tryptophan hydroxylase 2. In both lines of mice, adjunct 5-HTP SR synergized with SSRI to elevate 5-HTExt beyond the SSRI effect. We observed no adverse effect. Adjunct 5-HTP IR could not produce this therapy-like profile, producing transient 5-HTExt spikes and marked adverse effects. Integrated with a body of clinical data, our mouse data suggest that an adjunct 5-HTP SR drug could safely and effectively elevate 5-HTExt beyond the SSRI effect and represent a novel treatment for TRD.

RESUMEN

Of the many problems facing the US healthcare system, the shortage of behavioral health providers in outpatient settings is particularly profound. To address this issue, Boston׳s Brigham and Women׳s Hospital identified ways to incorporate behavioral health into primary care when it opened the South Huntington Primary Care clinic in August 2011. When the needs of its patients were more complex than anticipated, the clinic created assessment tools and refined care processes to identify, triage, and monitor patients with mental illness. Key insights from the South Huntington experience include. • Hiring for roles instead of training can decrease costs of implementation. • A process for reflection, assessment, and adaptation is a critical component of innovation. • Innovations must adapt to the specific needs of the local community. • Innovations are most effective when they reflect the capabilities of local providers.

RESUMEN

RATIONALE: Escitalopram appears to be a superior antidepressant to racemic citalopram. It has been hypothesized that binding of R-citalopram to the serotonin transporter (SERT) antagonizes escitalopram binding to and inhibition of the SERT, there by curtailing the elevation of extracellular 5-hydroxytryptamine (5-HTExt), and hence anti-depressant efficacy. Further, it has been suggested that a putative allosteric binding site is important for binding of escitalopram to the primary, orthosteric, site, and for R-citalopram's inhibition here of. OBJECTIVES: Primary: Investigate at the human (h)SERT, at clinical relevant doses, whether R-citalopram antagonizes escitalopram-induced 5-HTExt elevation. Secondary: Investigate whether abolishing the putative allosteric site affects escitalopram-induced 5-HTExt elevation and/or modulates the effect of R-citalopram. METHODS: Recombinant generation of hSERT transgenic mice; in vivo microdialysis; SERT binding; pharmacokinetics; 5-HT sensitive behaviors (tail suspension, marble burying). RESULTS: We generated mice expressing either the wild-type human SERT (hSERT(WT)) or hSERT carrying amino acid substitutions (A505V, L506F, I507L, S574T and I575T) collectively abolishing the putative allosteric site (hSERT(ALI/VFL+SI/TT)). One mg/kg escitalopram yielded clinical relevant plasma levels and brain levels consistent with therapeutic SERT occupancy. The hSERT mice showed normal basal 5-HTExt levels. Escitalopram-induced 5-HTExt elevation was not decreased by R-citalopram co-treatment and was unaffected by loss of the allosteric site. The behavioral effects of the clinically relevant escitalopram dose were small and tended to be enhanced by R-citalopram co-administration. CONCLUSIONS: We find no evidence that R-citalopram directly antagonizes escitalopram or that the putative allosteric site is important for hSERT inhibition by escitalopram.
