Long-term Results of Comprehensive Clubfoot Release Versus the Ponseti Method: Which Is Better?

Background

Clubfoot can be treated nonoperatively, most commonly using a Ponseti approach, or surgically, most often with a comprehensive clubfoot release. Little is known about how these approaches compare with one another at longer term, or how patients treated with these approaches differ in terms of foot function, foot biomechanics, or quality-of-life from individuals who did not have clubfoot as a child.

Questions/purposes

We compared (1) focused physical and radiographic examinations, (2) gait analysis, and (3) quality-of-life measures at long-term followup between groups of adult patients with clubfoot treated either with the Ponseti method of nonsurgical management or a comprehensive surgical release through a Cincinnati incision, and compared these two groups with a control group without clubfoot.

Methods

This was a case control study of individuals treated for clubfoot at two separate institutions with different methods of treatment between 1983 to 1987. One hospital used only the Ponseti method and the other mainly used a comprehensive clubfoot release. There were 42 adults (24 treated surgically, 18 treated with Ponseti method) with isolated clubfoot along with 48 healthy control subjects who agreed to participate in a detailed analysis of physical function, foot biomechanics, and quality-of-life metrics.

Results

Both treatment groups had diminished strength and motion compared with the control subjects on physical examination measures; however, the Ponseti group had significantly greater ankle plantar flexion ROM (p < 0.001), greater ankle plantar flexor (p = 0.031) and evertor (p = 0.012) strength, and a decreased incidence of osteoarthritis in the ankle and foot compared with the surgical group. During gait the surgical group had reduced peak ankle plantar flexion (p = 0.002), and reduced sagittal plane hindfoot (p = 0.009) and forefoot (p = 0.008) ROM during the preswing phase compared with the Ponseti group. The surgical group had the lowest overall ankle power generation during push off compared with the control subjects (p = 0.002). Outcome tools revealed elevated pain levels in the surgical group compared with the Ponseti group (p = 0.008) and lower scores for physical function and quality-of-life for both clubfoot groups compared with age-range matched control subjects (p = 0.01).

Conclusions

Although individuals in each treatment group experienced pain, weakness, and reduced ROM, they were highly functional into early adulthood. As adults the Ponseti group fared better than the surgically treated group because of advantages including increased ROM observed at the physical examination and during gait, greater strength, and less arthritis. This study supports efforts to correct clubfoot with Ponseti casting and minimizing surgery to the joints, and highlights the need to improve methods that promote ROM and strength which are important for adult function.

Estado actual y perspectivas futuras del trasplante de hepatocitos

The imbalance between the number of potential beneficiaries and available organs, originates the search for new therapeutic alternatives, such as Hepatocyte transplantation (HT).Even though this is a treatment option for these patients, the lack of unanimity of criteria regarding indications and technique, different cryopreservation protocols, as well as the different methodology to assess the response to this therapy, highlights the need of a Consensus Conference to standardize criteria and consider future strategies to improve the technique and optimize the results.Our aim is to review and update the current state of hepatocyte transplantation, emphasizing the future research attempting to solve the problems and improve the results of this treatment.     

The Effects of Bariatric Surgery on Colorectal Cancer Risk: Systematic Review and Meta-analysis

Obesity is an established risk factor for colorectal cancer (CRC) but the effects of bariatric surgery on CRC incidence are uncertain. A systematic review of six electronic databases identified 3691 articles. Four observational studies met our inclusion criteria and results were pooled using a random effects model. Meta-analysis of these four studies revealed that bariatric surgery was associated with a significantly (p?=?0.004) lower CRC incidence (RR?=?0.73, 95 % confidence interval, 0.58–0.90) when compared with obese non-operated individuals, i.e., bariatric surgery is associated with a 27 % lower CRC risk. However the evidence base is limited and these findings should be confirmed by future studies with improved designs.     

Profile of herbal and dietary supplements induced liver injury in Latin America: A systematic review of published reports

Hepatotoxicity related to HDS is a growing global health issue. We have undertaken a systematic review of published case reports and case series from LA from 1976 to 2020 to describe the clinical features of HDS related hepatotoxicity in this region. We search in PubMed, Web of Science, Scopus and specific LA databases according to PRISMA guidelines. Only HILI cases published in LA that met criteria for DILI definition were included. Duplicate records or reports that lacked relevant data that precluded establishing causality were excluded. Finally, 17 records (23 cases) were included in this review. Centella asiatica, Carthamus tinctorius, and Herbalife® were the most reported HDS culprit products, the main reason for HDS consumption was weight loss. The clinical characteristics of HDS hepatotoxicity in our study were compared to those of other studies in the USA, Europe and China showing a similar signature with predominance of young females, hepatocellular damage, a high rate of ALF and mortality, more frequent inadvertent re‐challenge and chronic damage. This study underscores the challenge in causality assessment when multi‐ingredients HDS are taken and the need for consistent publication practice when reporting hepatotoxicity cases due to HDS, to foster HDS liver safety particularly in LA.     

Incentives and Disincentives for the Treatment of Depression and Anxiety: A Scoping Review

Objective:

There is widespread support for primary care to help address growing mental health care demands. Incentives and disincentives are widely used in the design of health care systems to help steer toward desired goals. The absence of a conceptual model to help understand the range of factors that influence the provision of primary mental health care inspired a scoping review of the literature. Understanding the incentives that promote and the disincentives that deter treatment for depression and anxiety in the primary care context will help to achieve goals of greater access to mental health care.

Method:

A review of the literature was conducted to answer the question, how are incentives and disincentives conceptualized in studies investigating the treatment of common mental disorders in primary care? A comprehensive search of MEDLINE, PsycINFO, CINAHL, and Google Scholar was undertaken using Arksey and O’Malley’s 5-stage methodological framework for scoping reviews.

Results:

We identified 27 studies. A range of incentives and disincentives influence the success of primary mental health care initiatives to treat depression and anxiety. Six types of incentives and disincentives can encourage or discourage treatment of depression and anxiety in primary care: attitudes and beliefs, training and core competencies, leadership, organizational, financial, and systemic.

Conclusions:

Understanding that there are 6 different types of incentives that influence treatment for anxiety and depression in primary care may help service planners who are trying to promote improved mental health care.     

Postsecondary Pathways and Persistence for STEM Versus Non-STEM Majors: Among College Students with an Autism Spectrum Disorder

Little is known about postsecondary pathways and persistence among college students with an autism spectrum disorder (ASD). This study analyzed data from the National Longitudinal Transition Study-2, 2001–2009, a nationally representative sample of students in special education with an ASD who progressed from high school to postsecondary education. Findings suggest that most college students with an ASD enrolled in a 2-year community college at some point in the postsecondary careers (81 %). Those in science, technology, engineering and mathematics (STEM) fields were more likely to persist in a 2-year community college and were twice as likely to transfer from a 2-year community college to a 4-year university than their peers in the non-STEM fields. College persistence rates varied by gender, race, parent education level, and college pathway and major. Educational policy implications are discussed.     

Control over a stressor involves the posterior dorsal striatum and the act/outcome circuit

Controllable/escapable tailshocks (ESs) do not produce the behavioral and neurochemical outcomes produced by equal yoked uncontrollable/inescapable tailshocks (ISs). The prelimbic cortex is known to play a key role in mediating the protective effects of control. The concepts of act/outcome learning and control seem similar, and act/outcome learning is mediated by a circuit involving the prelimbic cortex and posterior dorsomedial striatum (DMS). Thus, we tested the involvement of the DMS in the protective effect of ES, in rats. First, we examined Fos immunoreactivity in both the DMS and dorsolateral striatum (DLS) after ES and yoked IS. We then investigated the effect of blocking DMS or DLS N‐methyl‐d ‐aspartate receptors with the specific antagonist D‐(‐)‐2‐amino‐5‐phosphopentanoic acid (D‐AP5) on the release of dorsal raphe nucleus serotonin (5‐HT) during ES, as well as on the level of anxiety produced by the ES experience 24 h later. ES, but not yoked IS, produced a large increase of Fos activity in the DMS. Consistent with the Fos data, D‐AP5 in the DMS, but not in the DLS, prevented the inhibition of dorsal raphe nucleus 5‐HT release normally produced by ES. Furthermore, D‐AP5 administered into the DMS before ES, but not into the DLS, increased anxiety 24 h later, leading to levels similar to those produced by IS. These results suggest that, as with appetitive act/outcome contingency learning, the protective effects of behavioral control over a stressor require the DMS.     

Safety of Epidural Analgesia in the Perioperative Care of Patients Undergoing Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy

Background

The perioperative coagulopathy, hemodynamic instability, and infectious complications that may occur during cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has raised concerns about the safety of epidural analgesia in patients undergoing such procedures.

Methods

We conducted a retrospective review of the perioperative anesthetic management of 215 adult patients who had undergone CRS with HIPEC with epidural analgesia. We reviewed epidural-related complications and analyzed the effect of early initiation of continuous epidural analgesia on estimated blood loss, intraoperative fluid administration, blood transfusion and vasopressor requirements, time to extubation, and length of stay.

Results

No epidural hematomas or abscesses were reported. Two patients (0.9 %) had delays in epidural removal because of thrombocytopenia, and two had epidural-site erythema (0.9 %). The majority of postoperative epidural-related hypotensive episodes were successfully treated with fluid boluses. Early initiation of epidural analgesic infusions (before HIPEC) was associated with significantly less surgical blood loss and fluid requirements (P = 0.005 and 0.02, respectively). Pre-HIPEC initiation of epidural infusions was not associated with a statistically significant difference in the following: volume of blood transfused, intraoperative vasopressors use, time to extubation, and length of hospital stay.

Conclusions

With close hematologic monitoring and particular attention to sterility, epidural analgesia can be safely provided to patients undergoing CRS with HIPEC. Early initiation of continuous epidural infusions during surgery could lead to decreased blood loss and less intraoperative fluid administration. Prospective randomized studies are required to further investigate these potential benefits.
