Mitragyna speciosa: Clinical, Toxicological Aspects and Analysis in Biological and Non-Biological Samples

The abuse of psychotropic substances is a well-known phenomenon, and many of them are usually associated with ancestral traditions and home remedies. This is the case of Mitragyna speciosa (kratom), a tropical tree used to improve work performance and to withstand great heat. According to several published studies, the main reasons for kratom consumption involve improving sexual performance and endurance, but also social and recreational uses for the feeling of happiness and euphoria; it is also used for medical purposes as a pain reliever, and in the treatment of diarrhea, fever, diabetes, and hypertension. However, this plant has gained more popularity amongst young people over the last years. Since it is available on the internet for purchase, its use is now widely as a drug of abuse, namely as a new psychoactive substance, being a cheaper alternative to opioids that does not require medical prescription in most countries. According to internet surveys by the European Monitoring Centre for Drugs and Drug Addiction in 2008 and 2011, kratom was one of the most widely supplied new psychoactive substances. The composition of kratom is complex; in fact, more than 40 different alkaloids have been identified in Mitragyna speciosa so far, the major constituent being mitragynine, which is exclusive to this plant. Besides mitragynine, alkaloids such as corynantheidine and 7-hydroxamitragynine also present pharmacological effects, a feature that may be attributed to the remaining constituents as well. The main goal of this review is not only to understand the origin, chemistry, consumption, and analytical methodologies for analysis and mechanism of action, but also the use of secondary metabolites of kratom as therapeutic drugs and the assessment of potential risks associated with its consumption, in order to aid health professionals, toxicologists, and police authorities in cases where this plant is present.
Quantitative assessment of nocturnal neural respiratory drive in children with and without obstructive sleep apnoea using surface EMG

What is the central question of this study? Recent studies have suggested potential utility of non‐normalized respiratory muscle EMG as an index of neural respiratory drive (NRD). Whether NRD measured using non‐normalized surface EMG of the lateral chest wall overlying the diaphragm (sEMGcw) recorded during nocturnal clinical polysomnography can differentiate children with and without obstructive sleep apnoea (OSA) is not known. What is the main finding and its importance? Non‐normalized sEMGcw was increased in children with OSA and an additional group of snoring children without OSA but subjectively increased respiratory effort compared with primary snorers. The sEMGcw has potential clinical utility in evaluation of children with sleep‐disordered breathing as an objective, non‐invasive, non‐volitional marker of NRD.
Time, Music, and Reverie

Time is an important source of containment vis-à-vis the pressure of affects and the nondimensional immensity of mental space experienced by difficult patients. A more articulated spatiotemporal integration can be facilitated by the analyst's musical “reverie” during intense emotional exchanges in analytic sessions. This reverie can be visual, olfactory, kinaesthetic, etc., no less than auditory or musical. Music is indeed connected with both the concrete world of bodily sensations and the symbolic expressions of culture, and may be an important transitional phenomenon in analytic communication on both unconscious and conscious levels. Two clinical cases are presented in which the patient's awareness of the passage of time, associated with the analyst's internal musical experiences, made it possible in one case to reduce intense panic attacks and, in the other, to overcome the patient's rigid obsessive defenses, giving him access to fluid and unforeseen emotions. In these two instances of working through, the perception of time helped establish confidence in the creative contribution of the “unheard melodies” (Keats) of affects to the functioning of thought.
How is women’s demand for caesarean section measured? A systematic literature review

Background Caesarean section rates are increasing worldwide, and since the 2000s, several researchers have investigated women’s demand for caesarean sections. Question The aim of this article was to review and summarise published studies investigating caesarean section demand and to describe the methodologies, outcomes, country characteristics and country income levels in these studies. Methods This is a systematic review of studies published between 2000 and 2017 in French and English that quantitatively measured women’s demand for caesarean sections. We carried out a systematic search using the Medline database in PubMed. Findings The search strategy identified 390 studies, 41 of which met the final inclusion criteria, representing a total sample of 3 774 458 women. We identified two different study designs, i.e., cross-sectional studies and prospective cohort studies, that are commonly used to measure social demand for caesarean sections. Two different types of outcomes were reported, i.e., the preferences of pregnant or non-pregnant women regarding the method of childbirth in the future and caesarean delivery following maternal request. No study measured demand for caesarean section during the childbirth process. All included studies were conducted in middle- (n = 24) and high-income countries (n = 17), and no study performed in a low-income country was found. Discussion Measuring caesarean section demand is challenging, and the structural violence leading to demand for caesarean section during childbirth while in the labour ward remains invisible. In addition, the caesarean section demand in low-income countries remains unclear due to the lack of studies conducted in these countries. Conclusion We recommend conducting prospective cohort studies to describe the social construction of caesarean section demand. We also recommend conducting studies in low-income countries because demand for caesarean sections in these countries is rarely investigated.
Ion Mobility Mass Spectrometry Uncovers the Impact of the Patterning of Oppositely Charged Residues on the Conformational Distributions of Intrinsically Disordered Proteins

The global dimensions and amplitudes of conformational fluctuations of intrinsically disordered proteins are governed, in part, by the linear segregation versus clustering of oppositely charged residues within the primary sequence. Ion mobility-mass spectrometry (IM-MS) affords unique advantages for probing the conformational consequences of the linear patterning of oppositely charged residues because it measures and separates proteins electrosprayed from solution on the basis of charge and shape. Here, we use IM-MS to measure the conformational consequences of charge patterning on the C-terminal intrinsically disordered region (p27 IDR) of the cell cycle inhibitory protein p27Kip1. We report the range of charge states and accompanying collisional cross section distributions for wild-type p27 IDR and two variants with identical amino acid compositions, κ14 and κ56, distinguished by the extent of linear mixing versus segregation of oppositely charged residues. Wild-type p27 IDR (κ31) and κ14, where the oppositely charged residues are more evenly distributed, exhibit a broad distribution of charge states. This is concordant with high degrees of conformational heterogeneity in solution. By contrast, κ56 with linear segregation of oppositely charged residues leads to limited conformational heterogeneity and a narrow distribution of charged states. Gas-phase molecular dynamics simulations demonstrate that the interplay between chain solvation and intrachain interactions (self-solvation) leads to conformational distributions that are modulated by salt concentration, with the wild-type sequence showing the most sensitivity to changes in salt concentration. These results suggest that the charge patterning within the wild-type p27 IDR may be optimized to sample both highly solvated and self-solvated conformational states.
The Burden of Childhood Atopic Dermatitis in the Primary Care Setting: A Report from the Meta-LARC Consortium

Background: Little is known about the burden of atopic dermatitis (AD) encountered in US primary care practices and the frequency and type of skin care practices routinely used in children. Objective: To estimate the prevalence of AD in children 0 to 5 years attending primary care practices in the United States and to describe routine skin care practices used in this population. Design: A cross-sectional survey study of a convenience sample of children under the age of 5 attending primary care practices for any reason. Setting: Ten primary care practices in 5 US states. Results: Among 652 children attending primary care practices, the estimated prevalence of ever having AD was 24% (95% CI, 21–28) ranging from 15% among those under the age of 1 to 38% among those aged 4 to 5 years. The prevalence of comorbid asthma was higher among AD participants compared to those with no AD, namely, 12% and 4%, respectively (P < .001). Moisturizers with high water:oil ratios were most commonly used (ie, lotions) in the non-AD population, whereas moisturizers with low water:oil content (ie, ointments) were most common when AD was present. Conclusions: Our study found a large burden of AD in the primary care practice setting in the US. The majority of households reported skin care practices that may be detrimental to the skin barrier, such as frequent bathing and the routine use of moisturizers with high water: oil ratios. Clinical trials are needed to identify which skin care practices are optimal for reducing the significant burden of AD in the community.
Cohort Study Examining the Association Between Blood Pressure and Cardiovascular Events in Patients With Peripheral Artery Disease

Background Hypertension is an important risk factor for cardiovascular events in patients with peripheral artery disease; however, optimal blood pressure targets for these patients are poorly defined. This study investigated the association between systolic blood pressure (SBP) and cardiovascular events in a prospectively recruited patient cohort with peripheral artery disease. Methods and Results A total of 2773 patients were included and were grouped according to SBP at recruitment (≤120 mm Hg, n=604; 121–140 mm Hg, n=1065; and >140 mm Hg, n=1104). Adjusted Cox proportional hazards analyses suggested that patients with SBP ≤120 mm Hg were at greater risk of having a major cardiovascular event (myocardial infarction, stroke, or cardiovascular death) than patients with SBP of 121–140 mm Hg (adjusted hazard ratio, 1.36; 95% CI, 1.08–1.72; P=0.009). Patients with SBP >140 mm Hg had an adjusted hazard ratio of 1.23 (95% CI, 1.00–1.51; P=0.051) of major cardiovascular events compared with patients with SBP of 121–140 mm Hg. These findings were similar in sensitivity analyses only including patients receiving antihypertensive medications or focused on patients with a minimum of 3 months of follow‐up. Conclusions This cohort study suggests that patients with peripheral artery disease and SBP ≤120 mm Hg are at increased risk of major cardiovascular events. The findings suggest caution in intensive SBP lowering in this patient group.
Prevalence and relationship of hypertriglyceridaemic–waist phenotype and type 2 diabetes mellitus among a rural adult Chinese population

Abstract Objective Limited information is available on the prevalence and effect of hypertriglyceridaemic–waist (HTGW) phenotype on the risk of type 2 diabetes mellitus (T2DM) in rural populations. Design In the present cross-sectional study, we investigated the prevalence of the HTGW phenotype and T2DM and the strength of their association among rural adults in China. Setting HTGW was defined as TAG >1·7 mmol/l and waist circumference (WC) ≥90 cm for males and ≥80 cm for females. Logistic regression analysis yielded adjusted odds ratios (aOR) relating risk of T2DM with HTGW. Participants Adults (n 12 345) aged 22·83–92·58 years were recruited from July to August of 2013 and July to August of 2014 from a rural area of Henan Province in China. Results The prevalence of HTGW and T2DM was 23·71 % (males: 15·35 %; females: 28·88 %) and 11·79 % (males: 11·15 %; females: 12·18 %), respectively. After adjustment for sex, age, smoking, alcohol drinking, blood pressure, physical activity and diabetic family history, the risk of T2DM (aOR; 95 % CI) was increased with HTGW (v. normal TAG and WC: 3·23; CI 2·53, 4·13; males: 3·37; 2·30, 4·92; females: 3·41; 2·39, 4·85). The risk of T2DM with BMI≥28·0 kg/m2, simple enlarged WC and simple disorders of lipid metabolism showed an increasing tendency (aOR=1·31, 1·75 and 2·32). Conclusions The prevalence of HTGW and T2DM has reached an alarming level among rural Chinese people, and HTGW is a significant risk factor for T2DM.
A combination pharmacotherapy of tapentadol and pregabalin to tackle centrally driven osteoarthritis pain

Many Osteoarthritis (OA) patients report with clinical features to their pain that cannot be explained by purely peripheral mechanisms. Yet, the analgesic agents available that tackle centrally driven chronic pain often provide only partial pain relief, or have dose‐limiting side effects. We explored a combination therapy of the centrally acting analgesic agents tapentadol and pregabalin, to investigate if they could be used in combination to provide superior analgesia.
A combination of photodynamic therapy and antimicrobial compounds to treat skin and mucosal infections: a systematic review

Background Antimicrobial photodynamic therapy (aPDT) is a growing approach to treat skin and mucosal infections. Despite its effectiveness, investigators have explored whether aPDT can be further combined with antibiotics and antifungal drugs. Objective To systematically assess the in vivo studies on the effectiveness of combinations of aPTD plus antimicrobials in the treatment of cutaneous and mucosal infections. Materials and methods Searches were performed in four databases (PubMed, EMBASE, Cochrane library databases, ClinicaTrials.gov) until July 2018. The pooled information was evaluated according to the PRISMA guidelines. Results 11 full-text articles were finally evaluated and included. The best aPDT combinations involved 5-aminolevulinic acid or phenothiazinium dye-based aPDT. In general, the combination shows benefits such as reducing treatment times, lowering drug dosages, decreasing drug toxicity, improving patient compliance and diminishing the risk of developing resistance. The mechanism of action may be that first aPDT damages the microbial cell wall or membrane, which allows better penetration of the antimicrobial drug. Limitations The number of studies was low, the protocols used were heterogeneous, and there was a lack of clinical trials. Conclusions The additive or synergistic effect of aPDT combined with antimicrobials could be promising to manage skin and mucosal infections, helping to overcome the microbial drug resistance.
“Like Death is Near”: Expressions of Suicidal and Homicidal Ideation in the Blog Posts of Family Caregivers of People with Dementia

Background: The challenges of providing care for someone with Alzheimer’s disease and related dementias (ADRD) have been associated with increased stress, poor mental and physical health, social isolation, and financial distress. More recently, caregiving has been associated with high rates of suicidal and homicidal ideation, but the research on these phenomena is limited. The present study analyzed a sample of blogs written by family caregivers of people with ADRD to explore thoughts of suicide and homicide expressed by these caregivers. Methods: Blogs written by self-identified informal caregivers of people with ADRD were identified using a systematic search method and data were analyzed using a qualitative thematic analysis. Results: Five themes related to thoughts of suicide and homicide by caregivers and people with ADRD were derived from the analysis: (1) end-of-life care; (2) thoughts of death and euthanasia by the person with ADRD; (3) surrogate decision making; (4) thoughts of suicide by the caregiver; and (5) thoughts of homicide and euthanasia by the caregiver. Conclusions: The results capture the reality of suicidal and homicidal thoughts among family caregivers of people with ADRD, supporting calls for more research on these complex topics and highlighting the need for changes to clinical practice to prevent thoughts from becoming behaviors or actions.
Mexican Origin Hispanic Men’s Perspectives of Physical Activity–Related Health Behaviors

Approximately 83% of Hispanic men of Mexican origin are overweight or obese, which are both associated with increased risk of chronic disease and all-cause mortality. Consequently, men of Mexican origin have some of the highest prevalence rates of obesity-related comorbidities. Physical activity (PA) may be an important strategy for Hispanic men of Mexican origin in reducing incidence and risk factors of lifestyle diseases. The current study engaged Spanish-speaking, Hispanic men of Mexican origin aged 24–64 years with overweight/obesity to examine perspectives of health behaviors related to PA. A total of 14 in-depth semistructured individual interviews were completed between September and November of 2015 and data analyzed using an iterative deductive–inductive thematic assessment strategy. The men suggested that their PA was hindered by (a) work-related energy and time constraints, (b) socioeconomic status (SES) and the need to prioritize work, (c) adaptations to majority population lifestyle norms, and (d) perceived lack of suitable access to PA-promoting spaces. The men provided valuable insight for strategies to improve PA interventions such as (a) accurately accounting for current PA levels of participants, including occupational and transportation PA, (b) considerations of family dynamics that influence PA-based behavior change, and (c) considerations of economic and geographical constraints that can be remediated. To improve effectiveness, future PA-related intervention research with Hispanic men of Mexican origin should consider methods that (a) account for transportation and occupational PA to better tailor PA to individual needs, (b) consider sociocultural and socioeconomic influences, (c) account for social support and accountability, and (d) consider economic and geographical constraints.
Association of PTPN1 polymorphisms with breast cancer risk: A case‐control study in Chinese females

Breast cancer (BC) risk, development, and prognosis were closely related to obesity, diabetes mellitus, and metabolic syndrome. Protein tyrosine phosphatase, non‐receptor type 1 (PTPN1) located on chromosome 20q13, could negatively regulate insulin and leptin signaling. In this study, we determined the association of PTPN1 polymorphisms with BC risk.
Addressing Community Needs During the Hurricane Response and Recovery Efforts Through Community Assessments for Public Health Emergency Response (CASPER)—United States Virgin Islands, 2017-2018

ABSTRACT Objectives Two category 5 storms hit the US Virgin Islands (USVI) within 13 days of each other in September 2017. This caused an almost complete loss of power and devastated critical infrastructure such as the hospitals and airports Methods The USVI Department of Health conducted 2 response Community Assessments for Public Health Emergency Response (CASPERs) in November 2017 and a recovery CASPER in February 2018. CASPER is a 2-stage cluster sampling method designed to provide household-based information about a community’s needs in a timely, inexpensive, and representative manner. Results Almost 70% of homes were damaged or destroyed, 81.2% of homes still needed repair, and 10.4% of respondents felt their home was unsafe to live in approximately 5 months after the storms. Eighteen percent of individual respondents indicated that their mental health was “not good” for 14 or more days in the past month, a significant increase from 2016. Conclusion The CASPERs helped characterize the status and needs of residents after the devastating hurricanes and illustrate the evolving needs of the community and the progression of the recovery process. CASPER findings were shared with response and recovery partners to promote data-driven recovery efforts, improve the efficiency of the current response and recovery efforts, and strengthen emergency preparedness in USVI.

Hospital ownership of postacute care providers and the cost of care.

BACKGROUND Hospitals are facing incentives to manage the total cost of care for episodes of illness, including the costs of inpatient care as well as the cost of care provided by physicians and postacute care (PAC) providers. PAC is an especially important component of the overall cost of care. One strategy hospitals employ in managing this cost is to own PAC providers. Prior work on the relationship between PAC ownership and cost has reached mixed conclusions. PURPOSE The aim of this study was to examine the associations between the episodic costs of care and hospital ownership of PAC providers, including skilled nursing facilities (SNFs), home health agencies (HHAs), and inpatient rehabilitation facilities (IRF). METHODOLOGY We examine panel data on hospital ownership of PAC providers from the American Hospital Association for 2013-2015 and cost of care data from Centers for Medicare & Medicaid Services' Value-Based Purchasing Program. Using ordinary least squares, we quantify the association between a hospital's PAC ownership choice (both ownership of any PAC provider and ownership of particular types of providers) and the episodic cost of care. RESULTS In 2015, 80% of hospitals owned some type of PAC provider. We find that ownership of SNFs and HHAs is associated with a lower episodic cost of care, whereas ownership of inpatient rehabilitation facilities is associated with higher episodic costs of care. The effects of ownership do not differ for hospitals that participate in a voluntary shared saving program (Bundled Payment for Care Improvement). CONCLUSION The effects of PAC ownership vary by the type of PAC provider owned. Our results suggest that ownership of SNFs and HHAs may be a viable strategy for success in reimbursement programs that reward hospitals for managing the total costs for episodes of care.
Clinical significance of alloantibodies in hand transplantation - a multicenter study.

BACKGROUND Donor-specific antibodies (DSA) have a strong negative correlation with long-term survival in solid organ transplantation. Although the clinical significance of DSA and antibody-mediated rejection (AMR) in upper extremity transplantation (UET) remains to be established, a growing number of single-center reports indicate their presence and potential clinical impact. METHODS We present a multicenter study assessing the occurrence and significance of alloantibodies in UET in reference to immunological parameters and functional outcome. RESULTS Our study revealed a high prevalence and early development of de novo DSA and non-DSA (43%, the majority detected within the first three post operative years). HLA class II mismatch correlated with antibody development, which in turn significantly correlated with the incidence of acute cellular rejection. Cellular rejections preceded antibody development in almost all cases. A strong correlation between DSA and graft survival or function cannot be statistically established at this early stage but a correlation with a lesser outcome seems to emerge. CONCLUSIONS While the phenotype and true clinical effect of AMR remain to be better defined, the high prevalence of DSA and the correlation with acute rejection highlight the need for optimizing immunosuppression, close monitoring and the relevance of an HLA class II match in UET recipients.
