Cord lipoma in minimally invasive surgical repairs of inguinal hernias: a prospective study.

Cord lipomas are frequent findings in laparoscopic inguinal hernia surgeries in male patients. The symptoms of lipoma and the potential benefits of removing them are often overlooked because the focus is on the primary pathology of the hernia itself. Current recommendations are to reduce this fatty content, when present. When inguinal cord lipomas are left untreated in inguinal hernia surgery they can potentially cause symptoms and be detected in follow-up imaging exams. The objective of this study was to study incidence of cord lipomas in a cohort operated on by a single group specializing in abdominal wall surgery, as well as to analyze the possible relationship of this finding with the patient's symptoms, the characteristics of the operated hernia and postoperative outcome. This is a prospective study of male patients operated on for inguinal hernia laparoscopically or robotically in a single reference center. Of the total of 141 hernias, the distribution according to European Hernia Society classification showed that 45.4% were lateral, 19.1% medial and 35.5% mixed, highlighting a variety in the presentation of hernias. Analysis of the size of the hernias revealed that the majority (35.5%) were ≤ 1.5 cm. Inguinal cord lipoma was present in 64.5% of the samples, with no statistically significant association between the presence of the lipoma and an indirect hernia sac or obesity. The incidence of surgical site occurrences (SSO) was 9,2%, with seroma and hematoma. No recurrences were observed during follow-up, indicating a successful approach. There were no statistically significant relationships between SSO, the presence of lipoma and indirect hernial sac.

Volumetry after botulinum toxin A: the impact on abdominal wall compliance and endotracheal pressure.

PURPOSE: Botulinum toxin type A (BTA) is an adjuvant tool used in the preoperative optimization of complex hernias before abdominal wall reconstruction (AWR). This study aims to investigate changes in the abdominal cavity and hernia sac dimensions after BTA application. METHOD: A prospective study with 27 patients with a hernia defect of ≥ 10 cm and loss of domain (LOD) ≥ 20% underwent AWR. Computed tomography (CT) measurements and volumetry before and after the application of BTA were performed. Intraoperative and postoperative outcomes were evaluated. RESULTS: Imaging post-BTA revealed hernia width reduction of 1.9 cm (p = 0.002), lateral abdominal wall muscle elongation of 3.1 cm (p < 0.001), hernia volume reduction (HV) from 2.9 ± 0.9L to 2.4 ± 0.8L (p < 0.001), increase in abdominal cavity volume (ACV) from 9.7 ± 2.5L to 10.3L ± 2.4L (p = 0.003), and a reduction in the HV/ACV ratio from 30.2 ± 5% to 23.4 ± 6% (p < 0.001). Fascial closure was achieved in 92.6% of cases and component separation was required in 78%. The average variation in pulmonary plateau pressure was 3.53 cmH2O, and there were no postoperative respiratory failure recorded. At the 90-day follow-up, the wound morbidity rate was 25%, unplanned readmissions were 11%, and hernia recurrence 7.4%. CONCLUSION: BTA produces measurable volumetric changes in abdominal wall and appears to facilitate fascial closure. Further studies are required to determine the role of BTA in the surgical armamentarium for complex hernia repair.

Reliability of a novel point of care device for monitoring diabetic peripheral neuropathy.

We aimed to assess DPNCheck's reliability for repeated sural nerve conduction (NC) parameters. This post hoc analysis used data from the randomized controlled ACUDPN trial assessing NC of the N. Suralis every eight weeks over a 6-month period in 62 patients receiving acupuncture against diabetic peripheral neuropathy (DPN) symptoms. The reliability of DPNCheck for nerve conduction velocity and amplitude was assessed using intraclass correlation coefficients (ICC) and was calculated using data from single time points and repeated measures design. The results of the NC measurements were correlated with the Total Neuropathy Score clinical (TNSc). Overall, for both nerve velocity and amplitude, the reliability at each measurement time point can be described as moderate to good and the reliability using repeated measures design can be described as moderate. Nerve velocity and amplitude showed weak correlation with TNSc. DPNCheck's reliability results question its suitability for monitoring DPN's progression. Given the limitation of our analysis, a long-term, pre-specified, fully crossed study should be carried out among patients with DPN to fully determine the suitability of the device for DPN progression monitoring. This was the first analysis assessing the reliability of the DPNCheck for DPN progression monitoring using data from multiple collection time points.

Systematic review and meta-analysis of the pre-operative application of botulinum toxin for ventral hernia repair.

PURPOSE: Surgical repair of large hernia defects requires detailed pre-operative planning, particularly in cases with loss of domain. This situation often hampers mid-line reconstruction, even after component separation, when the size of the hernia is disproportional to the volume of the abdominal area. In this case, other strategies may be needed to place the viscera back into the abdominal cavity after reducing the hernia sac. The administration of botulinum toxin prior to the surgical procedure has been indicated as an adjunct for more complex cases. This results in stretching of the lateral musculature of the abdomen, allowing midline approximation. In addition, the application of botulinum toxin alone has been investigated as a means of downstaging in the management of ventral hernias, thereby precluding component separation and enabling primary closure of the midline by placement of mesh within the retromuscular space using the Rives Stoppa technique. METHODS: Systematic review of the literature for observational studies involving patients undergoing pre-operative application of botulinum toxin for ventral hernia repair was conducted according to the PRISMA guidelines. RESULTS: Advance of the lateral musculature of the abdomen by an average of 4.11 cm with low heterogeneity, as well as low rates of surgical site infection (SSI), surgical site occurrences (SSO) and recurrence, was shown. CONCLUSION: Pre-operative application of botulinum toxin for ventral hernia repair promoted an increase in the length of the lateral musculature of the abdomen which can help improve the outcomes of morbidity and recurrence.

Technical aspects of inguino scrotal hernia surgery in developing countries.

PURPOSE: Technical aspects of inguinoscrotal herniorrhaphy performed in low to middle income countries (LMICs) are described here to help surgeons who will operate on these challenging hernias in austere settings. METHODS: Technical considerations related to operative repair were delineated with the consensus of 7 surgeons with extensive experience in inguinoscrotal hernia repair in LMICs. Important steps and illustrations were prepared accordingly. The anatomical and pathologic differences and technical implications of operating in limited resource settings are emphasized with suggestions to approach anticipated challenges. Pre-operative evaluation, anesthetic considerations, and technical guidelines are offered in context. RESULTS: The authors have cumulatively performed over 1775 inguinoscrotal Lichtenstein operations in LMICs. While dedicated, reliable, long-term follow-up is unavailable from LMICs, one author reports outcomes with 5 year follow-up from the HerniaMed registry using the identical technique in similarly classed hernias. In 90 inguinoscrotal Lichtenstein repair patients (78.3% follow-up), there was one recurrence, low rates of chronic pain (2.2% at rest, 4.4% with activity), and low rates of reintervention (1.1%). CONCLUSION: There is a difference between inguinal hernias found in LMICs and those seen in high-income countries with larger, chronic, and more technically challenging pathology. The consequences of intra-operative complications can be catastrophic in a LMIC. Technical measures are offered to improve outcomes, avoid and manage complications, and provide optimal care to this important population.

Homeopathy for seasonal allergic rhinitis: rationale, design and methods of the three-armed randomized controlled HOMEOSAR trial.

BACKGROUND: Patients with seasonal allergic rhinitis (SAR) frequently use homeopathic therapy. Although there is some evidence that homeopathy may be effective in treating symptoms of SAR, there is a lack of high-quality clinical trials. Therefore, the aim of the homeopathy for SAR (HOMEOSAR) trial is to determine the efficacy of individualized or standardized homeopathic drug treatment compared to placebo regarding rhinitis-related quality of life in patients with SAR. METHODS: This randomized, placebo-controlled, double-blind, three-armed intervention study will be conducted at two university hospital outpatient clinics for complementary and integrative medicine in Berlin and in 12 office-based practices specializing in homeopathic treatment in Germany. A total of 270 patients with clinical symptoms of SAR and positive allergy test to birch and grass pollen will receive homeopathic anamnesis and subsequently be randomized into (a) standardized homeopathic drug treatment with Galphimia Glauca (potency D6), (b) individualized homeopathic drug treatment (D6), or (c) placebo. All three groups can receive on-demand rescue medication as needed. Treatment will consist of two consultations and daily intake of the study medication for 4 weeks during the pollen season. The primary outcome is the mean overall score of the Rhinitis Quality of Life Questionnaire (RQLQ) in weeks 3 and 4, analyzed using analysis of covariance (adjusted for baseline RQLQ overall score and study center). A closed testing procedure will be used to control the overall type I error comparing the 3 treatment groups. Secondary outcomes include the overall RQLQ and its seven domain scores, responder status (decrease in RQLQ overall score of at least 0.5 points compared to the baseline value), use of rescue medication, intensity of total and individual SAR symptoms based on visual analog scale, generic health-related quality of life, safety, utilization of health care resources and associated costs. In addition, a qualitative data analysis is planned. CONCLUSION: The results of our study will contribute to clarifying the possible therapeutic effects of homeopathic drug treatment for patients with SAR. TRIAL REGISTRATION: This study has been registered in the German Clinical Trial Registry with trial ID DRKS00018081 on June 09, 2020.

The Impact of Tax Refund Delays on the Experience of Hardship Among Lower-Income Households.

The Earned Income Tax Credit (EITC) provides substantial financial support to low-income workers in the USA, yet around a quarter of EITC payments are estimated to be erroneous or fraudulent. Beginning in 2017, the Protecting Americans from Tax Hikes Act of 2015 requires the Internal Revenue Service to spend additional time processing early EITC claims, delaying the issuance of tax refunds. Leveraging unique data, this paper investigates how delayed tax refunds affected the experience of hardship and unsecured debt among EITC recipients. Results indicate that early filers experienced increased food insecurity relative to later filers after the implementation of the refund delay.

Acupuncture in diabetic peripheral neuropathy-protocol for the randomized, multicenter ACUDPN trial.

BACKGROUND: Acupuncture is used to treat patients with diabetic peripheral neuropathy; however, the evidence is unclear. We present the design and methodology of the ACUDPN (ACUpuncture in Diabetic Peripheral Neuropathy) trial, which investigates the effectiveness of acupuncture for the treatment of diabetic peripheral neuropathy (DPN) symptoms. The aim of this study is to investigate whether acupuncture is effective for the treatment of DPN symptoms. METHODS: This study is a two-armed, randomized, controlled, parallel group, open-label, confirmatory, multicenter trial (8-week intervention period plus 16 weeks of follow-up). Physicians in outpatient units in Germany who specialize in acupuncture treatment will treat 110 diabetes type II patients with clinical symptoms of peripheral neuropathy in the feet and legs with signs of neuropathy according to nerve conduction testing. The patients will be randomized in a 1:1 ratio to one of the following two groups: (a) semi-standardized acupuncture plus routine care or (b) routine care alone. Acupuncture will consist of 12 treatments per patient over 8 weeks. The primary outcome will be the overall DPN-related complaints in the extremities after 8 weeks as measured by the Visual Analog Scale (VAS). Further outcome measures will include DPN-related pain, the Neuropathic Pain Symptom Inventory (NPSI), Diabetic Peripheral Neuropathic Pain Impact (DPNPI) scores, and nerve conduction parameters of the sural nerve at weeks 8, 16, and 24. DISCUSSION: The results of this trial will be available in 2021 and will help clarify whether acupuncture can be considered effective for the treatment of DPN with regard to the subdimensions of the neuropathic clinical picture.

Occurrence and determinants of parental psychosocial stress and mental health disorders in parents and their children in early childhood: rationale, objectives, and design of the population-based SKKIPPI cohort study.

PURPOSE: The postnatal period is a vulnerable time for parents and children but epidemiological and health care utilisation data for Germany on parental mental health during early childhood is scarce. This protocol describes the rationale, aim and study design of a population-based cohort study to assess the occurrence and determinants of psychosocial stress and mental health disorders, as well as the use and cost of health care and social services in early childhood. METHODS: As part of the collaborative SKKIPPI project, we will contact a random sample of 30,000 infants listed in the residents' registration offices of three German towns and we expect to include 6,000 mother-child pairs. Both parents are invited to fill out an online screening questionnaire. Mothers with indications of psychosocial stress will be interviewed to assess mental health disorders, regulatory problems of their children, as well as health care and social services utilisation, with a follow-up assessment after 6 months. RESULTS: After description of sociodemographic and health data, we will analyse occurrences, patterns, and potential determinants (maternal age, social status, household factors, migration status etc.) of psychosocial stress and mental health disorders in the mothers and their children in early childhood. CONCLUSIONS: Our study will identify potential risk and protective factors for postnatal mental health and health care utilization of psychosocially burdened families. This will help to improve prevention and treatment strategies to strengthen the parent-child relationship, to reduce persisting vulnerability of children, and to improve health care and social services. TRIAL REGISTRATION: The study has been registered in the German Clinical Trial Registry on February 8th 2019 (DRKS-ID: DRKS00016653).

Efficacy of Parent-Infant-Psychotherapy with mothers with postpartum mental disorder: study protocol of the randomized controlled trial as part of the SKKIPPI project.

BACKGROUND: After the birth of a child, many mothers and fathers experience postpartum mental disorders like depression, anxiety, obsessive-compulsive disorder, stress or other illnesses. This endangers the establishment of a secure attachment between the children and their primary caregivers. Early problems in parent-child interaction can have adverse long-term effects on the family and the child's well-being. In order to prevent a transgenerational transmission of mental disorders, it is necessary to evaluate psychotherapeutic interventions that target psychologically burdened parents of infants or toddlers. The aim of this trial is to investigate the efficacy of Parent-Infant-Psychotherapy (PIP) for mothers with postpartum mental disorder and their infants (0-12 months). METHODS/DESIGN: In this open, randomized controlled intervention trial 180 mother-infant-dyads will be included and randomly allocated to 12 sessions of PIP or care as usual. The interventions take place either in inpatient adult psychiatric departments or in outpatient settings with home visits. The primary outcome is the change in maternal sensitivity assessed by the Sensitivity subscale of the Emotional Availability Scale (EAS) through videotaped dyadic play-interactions after 6 weeks. Secondary outcomes are maternal psychopathology, stress, parental reflective functioning, infant development and attachment after 6 weeks and 12 months. In addition, maternal attachment (AAI) and reflective functioning (AAI) will be analyzed as potential moderators, and resource usage in the German health system as well as associated costs will be evaluated. DISCUSSION: There is increasing demand for well-controlled studies on psychotherapeutic interventions in the postpartum period that do not only focus on particular risk groups. This randomized controlled trial (RCT) represents one of the first studies to investigate the efficacy of PIP in inpatient psychiatric departments and outpatient care centers in Germany. The results will fill knowledge gaps on the factors contributing to symptom reduction in postpartum mental disorders and improvements in mother-child relationships and help in developing preventive and therapeutic strategies for the fragmented German health care system.

Hernia recurrence inventory: inguinal hernia recurrence can be accurately assessed using patient-reported outcomes.

PURPOSE: Relying solely on in-person encounters to assess long-term outcomes of hernia repair leads to substantial loss of information and patients lost-to-follow-up, hindering research and quality improvement initiatives. We aimed to determine if inguinal hernia recurrences could be assessed using the Ventral Hernia Recurrence Inventory (VHRI), a previously existing patient-reported outcome (PRO) tool that can be administered through the telephone and has already been validated for diagnosing ventral hernia recurrence. METHODS: A prospective, multicentric comparative study was conducted. Adult patients from two centers (United States and Brazil) at least 1 year after open or minimally invasive inguinal hernia repair were asked to answer the questions of the VHRI in relation to their prior repair. A physical exam was then performed by a blinded surgeon. Testing characteristics and diagnostic performance of the PRO were calculated. Patients with suspected recurrences were preferentially recruited. RESULTS: 128 patients were enrolled after 175 repairs. All patients answered the VHRI and were further examined, where a recurrence was present in 32% of the repairs. Self-reported bulge and patient perception of a recurrence were highly sensitive (84-94%) and specific (93-94%) for the diagnosis of an inguinal hernia recurrence. Test performance was similar in the American and Brazilian populations despite several baseline differences in demographic and clinical characteristics. CONCLUSION: The VHRI can be used to assess long-term inguinal hernia recurrence and should be reestablished as the Hernia Recurrence Inventory (HRI). Its implementation in registries, quality improvement efforts, and research could contribute to improving long-term follow-up rates in hernia patients.

Combined open and laparoscopic approach for repair of flank hernias: technique description and medium-term outcomes of a single surgeon.

PURPOSE: A residual bulge in the lateral abdominal wall is a reason for patient dissatisfaction after flank hernia repair (FHR). We hypothesized that combining a laparoscopically-placed intraperitoneal mesh (IPOM) with onlay hernia repair performed through a small open incision would increase repair durability and decrease such residual bulges. We aim to report our medium-term outcomes with this technique. METHODS: Patients who have undergone FHR using the technique described above from March 2013 through June 2017 were identified in a prospectively maintained database. Outcomes of interest included surgical site infections (SSI), surgical site occurrences (SSO), surgical site occurrences requiring procedural intervention (SSOPI) and hernia recurrence. RESULTS: Sixteen patients were identified (62% females; mean age 59 ± 8 years, mean body mass index 29.5 kg/m2). Mean hernia width was. 6.4 ± 3 cm and 31% were recurrent hernias previously repaired through an onlay approach. Mean operative time was 159 ± 40 min, fascial closure was achieved in all cases, and there were no intraoperative complications. Median length of stay was 3 days (IQR 3-4), and there were no unplanned readmissions or reoperations. At a median 37-month follow-up (IQR 21-55), wound morbidity rate was 12.5% (2 seromas). There were no SSI/SSOPI and one hernia recurrence (6%) was detected at 12 months postoperatively. CONCLUSION: Combining laparoscopic IPOM with open onlay hernia repair resulted in low recurrence and acceptable wound morbidity rates, with no residual bulges noted at medium-term follow-up. Further studies with larger number of patients and other surgeon's experiences are necessary to determine the role of such technique in the surgical armamentarium for flank hernia repair.

Pulsatile dry cupping in chronic low back pain - a randomized three-armed controlled clinical trial.

BACKGROUND: We aimed to investigate the effectiveness of two different forms of dry pulsatile cupping in patients with chronic low back pain (cLBP) compared to medication on demand only in a three-armed randomized trial. METHODS: 110 cLBP patients were randomized to regular pulsatile cupping with 8 treatments plus paracetamol on demand (n = 37), minimal cupping with 8 treatments plus paracetamol on demand (n = 36) or the control group with paracetamol on demand only (n = 37). Primary outcome was the pain intensity on a visual analogue scale (VAS, 0-100 mm) after 4 weeks, secondary outcome parameter included VAS pain intensity after 12 weeks, back function as measured with the 'Funktionsfragebogen Hannover Rücken' (FFbH-R) and health related quality of life questionnaire Short form 36 (SF-36) after 4 and 12 weeks. RESULTS: The mean baseline-adjusted VAS after 4 weeks was 34.9 mm (95% CI: 28.7; 41.2) for pulsatile cupping, 40.4 (34.2; 46.7) for minimal cupping and 56.1 (49.8; 62.4) for control group, resulting in statistically significant differences between pulsatile cupping vs. control (21.2 (12.2; 30.1); p < 0.001) and minimal cupping vs. control (15.7 (6.9; 24.4); p = 0.001). After 12 weeks, mean adjusted VAS difference between pulsatile cupping vs. control was 15.1 ((3.1; 27.1); p = 0.014), and between minimal cupping vs. control 11.5 ((- 0.44; 23.4); p = 0.059). Differences of VAS between pulsatile cupping and minimal cupping showed no significant differences after 4 or 12 weeks. Pulsatile cupping was also better (- 5.8 (- 11.5;-0.1); p = 0.045) compared to control for back function after 4 weeks, but not after 12 weeks (- 5.4 (- 11.7;0.8); p = 0.088), pulsatile cupping also showed better improvements on SF-36 physical component scale compared to control at 4 and 12 weeks (- 5.6 (- 9.3;-2.0); p = 0.003; - 6.1 (- 9.9;-2.4); p = 0.002). For back function and quality of life minimal cupping group was not statistically different to control after 4 and 12 weeks. Paracetamol intake did not differ between the groups (cupping vs. control (7.3 (- 0.4;15.0); p = 0.063); minimal cupping vs. control (6.3 (- 2.0;14.5); p = 0.133). CONCLUSIONS: Both forms of cupping were effective in cLBP without showing significant differences in direct comparison after four weeks, only pulsatile cupping showed effects compared to control after 12 weeks. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (identifier: NCT02090686 ).

[Drug therapy safety at the transition from hospital to community medicine]. / Arzneimitteltherapiesicherheit an der stationär-ambulanten Schnittstelle.

OBJECTIVE: We evaluated the qualitative and quantitative changes of medications during the stay on a geriatric-psychiatric ward where the medication was optimized by a clinical pharmacist, and after discharge. The goal of the study was to analyze the continuity of the medication at the transfer from hospital to ambulatory care. METHODS: We interviewed 41 patients on the phone about their drug regimen 4 and 12 weeks after discharge. Medications were compared to their discharge medication. The number of medications from the PRISCUS list of inappropriate medications for the elderly as well as the number of drug interactions was documented. The drug interaction database MediQ was used to identify and classify the drug-drug interactions. RESULTS: During the hospitalization of the patients, 101 interventions of the clinical pharmacist were recommended and accepted. In cooperation with the physicians, the number of drug interactions decreased by 44% and the number of PRISCUS list medications by 42%. Only 4 weeks after discharge, 54 drugs for 27 patients (66%) had already been changed. During the following 8 weeks, another 44 medications were changed in 14 patients (35%). The total number of drugs after discharge did not change. The number of moderate drug interactions (p = 0.17) of medications from the PRISCUS list increased (p = 0.77), but not significantly. CONCLUSION: While the interventions of a clinical pharmacist can lead to a reduction in drug interactions and inappropriate medication for the elderly during the hospitalization, the medication was changed after discharge in numerous cases. In a detailed analysis it was found that some of the changes increased the number of drug interactions as well as the number of potentially inappropriate medications for the elderly. A drug interaction check after discharge could prevent drug interactions and medication errors. Also the nationwide medication plan can help to prevent medication errors by the prescribing physician as well as by the patient.

[Validation of interaction databases in psychopharmacotherapy]. / Validierung von Interaktionsdatenbanken in der Psychopharmakotherapie.

BACKGROUND: Drug-drug interaction databases are an important tool to increase drug safety in polypharmacy. There are several drug interaction databases available but it is unclear which one shows the best results and therefore increases safety for the user of the databases and the patients. So far, there has been no validation of German drug interaction databases. GOAL: Validation of German drug interaction databases regarding the number of hits, mechanisms of drug interaction, references, clinical advice, and severity of the interaction. METHODS: A total of 36 drug interactions which were published in the last 3-5 years were checked in 5 different databases. Besides the number of hits, it was also documented if the mechanism was correct, clinical advice was given, primary literature was cited, and the severity level of the drug-drug interaction was given. RESULTS: All databases showed weaknesses regarding the hit rate of the tested drug interactions, with a maximum of 67.7% hits. The highest score in this validation was achieved by MediQ with 104 out of 180 points. PsiacOnline achieved 83 points, arznei-telegramm® 58, ifap index® 54 and the ABDA-database 49 points. Based on this validation MediQ seems to be the most suitable databank for the field of psychopharmacotherapy. DISCUSSION: The best results in this comparison were achieved by MediQ but this database also needs improvement with respect to the hit rate so that the users can rely on the results and therefore increase drug therapy safety.

The sex-shift in single disease and multimorbid asthma and rhinitis during puberty - a study by MeDALL.

BACKGROUND: Cross-sectional studies suggested that allergy prevalence in childhood is higher in boys compared to girls, but it remains unclear whether this inequality changes after puberty. We examined the sex-specific prevalence of asthma and rhinitis as single and as multimorbid diseases before and after puberty onset in longitudinal cohort data. METHODS: In six European population-based birth cohorts of MeDALL, we assessed the outcomes: current rhinitis, current asthma, current allergic multimorbidity (ie, concurrent asthma and rhinitis), puberty status and allergic sensitization by specific serum antibodies (immunoglobulin E) against aero-allergens. With generalized estimating equations, we analysed the effects of sex, age, puberty (yes/no) and possible confounders on the prevalence of asthma and rhinitis, and allergic multimorbidity in each cohort separately and performed individual participant data meta-analysis. FINDINGS: We included data from 19 013 participants from birth to age 14-20 years. Current rhinitis only affected girls less often than boys before and after puberty onset: adjusted odds ratio for females vs males 0.79 (95%-confidence interval 0.73-0.86) and 0.86 (0.79-0.94), respectively (sex-puberty interaction P = .089). Similarly, for current asthma only, females were less often affected than boys both before and after puberty onset: 0.71, 0.63-0.81 and 0.81, 0.64-1.02, respectively (sex-puberty interaction P = .327). The prevalence of allergic multimorbidity showed the strongest sex effect before puberty onset (female-male-OR 0.55, 0.46-0.64) and a considerable shift towards a sex-balanced prevalence after puberty onset (0.89, 0.74-1.04); sex-puberty interaction: P < .001. INTERPRETATION: The male predominance in prevalence before puberty and the "sex-shift" towards females after puberty onset were strongest in multimorbid patients who had asthma and rhinitis concurrently.

Is there a sex-shift in prevalence of allergic rhinitis and comorbid asthma from childhood to adulthood? A meta-analysis.

BACKGROUND: Allergic rhinitis and asthma as single entities affect more boys than girls in childhood but more females in adulthood. However, it is unclear if this prevalence sex-shift also occurs in allergic rhinitis and concurrent asthma. Thus, our aim was to compare sex-specific differences in the prevalence of coexisting allergic rhinitis and asthma in childhood, adolescence and adulthood. METHODS: Post-hoc analysis of systematic review with meta-analysis concerning sex-specific prevalence of allergic rhinitis. Using random-effects meta-analysis, we assessed male-female ratios for coexisting allergic rhinitis and asthma in children (0-10 years), adolescents (11-17) and adults (> 17). Electronic searches were performed using MEDLINE and EMBASE for the time period 2000-2014. We included population-based observational studies, reporting coexisting allergic rhinitis and asthma as outcome stratified by sex. We excluded non-original or non-population-based studies, studies with only male or female participants or selective patient collectives. RESULTS: From a total of 6539 citations, 10 studies with a total of 93,483 participants met the inclusion criteria. The male-female ratios (95% CI) for coexisting allergic rhinitis and asthma were 1.65 (1.52; 1.78) in children (N = 6 studies), 0.61 (0.51; 0.72) in adolescents (N = 2) and 1.03 (0.79; 1.35) in adults (N = 2). Male-female ratios for allergic rhinitis only were 1.25 (1.19; 1.32, N = 5) in children, 0.80 (0.71; 0.89, N = 2) in adolescents and 0.98 (0.74; 1.30, N = 2) in adults, respectively. CONCLUSIONS: The prevalence of coexisting allergic rhinitis and asthma shows a clear male predominance in childhood and seems to switch to a female predominance in adolescents. This switch was less pronounced for allergic rhinitis only.

Humanitarianism in surgery.

PURPOSE: Humanitarianism is by definition a moral of kindness, benevolence and sympathy extended to all human beings. In our view as surgeons working in underserved countries, humanitarianism means performing the best operation in the best possible circumstances with high income country (HIC) results and training in-country surgeons to do the same. Hernia Repair for the Underserved (HRFU), a not for profit organization, is developing a long term public health initiative for hernia surgery in Western Hemisphere countries. We report the progress of HRFUs methods to render humanitarian care. METHODS: In a collaborative effort, Creighton University and the Institute for Latin American Concern developed an outpatient surgery site for hernia surgery in Santiago, Dominican Republic. Based on this experience, we developed a sustainable care model by recruiting American and European Hernia Society expert surgeons, staff members they recommended, building relationships with local and industry partners, and selecting local surgeons to be trained in mesh hernioplasty. HRFU then extended the care model to other Western Hemisphere countries. RESULTS: Between 2004 and 2015, the HRFU elective hernia morbidity and mortality rates for 2052 hernia operations were 0.7 and 0%, respectively. This is consistent with outcomes from HICs and confirms the feasibility of a public health initiative based on the principles of the Preferential Option for the Poor. CONCLUSIONS: HRFU has recorded HIC morbidity and mortality rates for hernia surgery in low and middle income countries and has initiated a new surgical training model for sustainability of effect.

Discharge management strategies and post-discharge care interventions for depression - Systematic review and meta-analysis.

BACKGROUND: Patients with depression require treatment continuity when discharged from inpatient care. Interventions aimed at optimizing transition into outpatient care may be effective in preventing symptom deterioration and readmission. We aimed to evaluate the effectiveness of care transition interventions for patients with depression after psychiatric hospitalization. METHODS: Systematic review and random-effects meta-analysis of controlled trials. Primary outcomes were readmissions and symptoms of depression. The control condition was treatment as usual. RESULTS: We included 16 publications reporting the results of 13 different studies. Studies were heterogeneous concerning patient selection and interventional approach. Effects on readmissions and depression symptoms were non-significant in meta-analysis of 8 studies/710 patients and 7 studies/592 patients, respectively. Overall risk ratio for readmission during follow-up was 0.65 (95% CI [0.42;1.01], p=0.06), standardized mean difference for depression symptoms was -0.09 (95% CI [-0.37;0.19], p=0.53). Subgroup analyses indicated no preference for a specific interventional strategy. Data point to considerable risk for selection and publication bias. LIMITATIONS: Included studies are heterogeneous; subgroups are often small and may not attain the power to detect effects. Reasonable classification of interventions into groups of comparable approaches was a challenge and may be arbitrary in some cases. CONCLUSIONS: This systematic review and meta-analysis could not identify any convincingly effective interventional transition approach for patients with depression after psychiatric hospitalization. Current evidence regarding discharge management for depression is limited, heterogeneous and potentially prone to bias. Interventions might be more appropriate for patients with other diagnoses than depression. Further high-quality randomized studies are required.

Design and implementation of the Americas Hernia Society Quality Collaborative (AHSQC): improving value in hernia care.

PURPOSE: Wide variation in care and costs exists regarding the management of abdominal wall hernias, with unproven benefit for many therapies. This work establishes a specialty society-based solution to improve the quality and value of care delivered to hernia patients during routine clinical management on a national scale. METHODS: The Americas Hernia Society Quality Task Force was charged by the Americas Hernia Society leadership to develop an initiative that utilizes the concepts of continuous quality improvement (CQI). A disease-based registry was created to collect information for CQI incorporating real-time outcome reporting, patient reported outcomes, stakeholder engagement, and collaborative learning methods to form a comprehensive quality improvement effort. RESULTS: The Americas Hernia Society Quality Collaborative (AHSQC) was formed with the mission to provide health care professionals real-time information for maximizing value in hernia care. The initial disease areas selected for CQI were incisional and parastomal hernias with ten priorities encompassing the spectrum of care. A prospective registry was created with real-time analytic feedback to surgeons. A data assurance process was implemented to ensure maximal data quality and completeness. Four collaborative meetings per year were established to meet the goals of the AHSQC. As of the fourth quarter 2014, the AHSQC includes nearly 2377 patients at 38 institutions with 82 participating surgeons. CONCLUSIONS: The AHSQC has been established as a quality improvement initiative utilizing concepts of CQI. This ongoing effort will continually refine its scope and goals based on stakeholder input to improve care delivered to hernia patients.
