The Combined Relationship of Prescription Drug Monitoring Program Enactment and Medical Cannabis Laws with Chronic Pain-Related Healthcare Visits.

U.S. state electronic prescription drug monitoring programs (PDMPs) are associated with reduced opioid dispensing among people with chronic pain and may impact use of other chronic pain treatments. In states with medical cannabis laws (MCLs), patients can use cannabis for chronic pain management, reducing their need for chronic-pain related treatment visits and moderating effects of PDMP laws. Given high rates of chronic pain among Medicaid enrollees, we examined associations between PDMP enactment in the presence or absence of MCL on chronic pain-related outpatient and emergency department (ED) visits. We created annual cohorts of Medicaid enrollees with chronic pain diagnoses using national Medicaid claims data from 2002-2013 and 2016. Negative binomial hurdle models produced adjusted odds ratios (aOR) for the likelihood of any chronic pain-related outpatient or ED visit and incident rate ratios (IRR) for the rate of visits among patients with ≥ 1 visit. Medicaid enrollees aged 18-64years with chronic pain (N = 4,878,462). A 3-level state-year variable with the following categories: 1) no PDMP, 2) PDMP enactment in the absence of MCL, or 3) PDMP enactment in the presence of MCL. Healthcare codes for chronic pain-related outpatient and ED visits each year. The sample was primarily female (67.2%), non-Hispanic White (51.2%), and ages 40-55years (37.2%). Compared to no-PDMP states, PDMP enactment in the absence of MCL was not associated with chronic pain-related outpatient visits but PDMP enactment in the presence of MCL was associated with lower odds of chronic pain-related outpatient visits (aOR = 0.81, 95% CI:0.71-0.92). PDMP enactment was not associated with ED visits, irrespective of MCL. During a period of PDMP and MCL expansion, our findings suggest treatment shifts for persons with chronic pain away from outpatient settings, potentially related to increased use of cannabis for chronic pain management.

Association of Abdominal Aortic Calcification and Clinical Outcomes in LDH Patients Treated with Endoscopic Lumbar Discectomy.

To determine any significant associations between abdominal aortic calcification (AAC) and clinical manifestations of pain symptoms following endoscopic lumbar discectomy. Patients sequentially presenting with a history of unilateral radiculopathy with or without back pain, and with magnetic resonance imaging (MRI)-confirmed diagnosis of posterolateral disc herniation between August 2021 and December 2023 were eligible for inclusion in the study. All patients underwent endoscopic discectomy at our center during the study period. AAC stages were classified based on the Kauppila classification system using lateral lumbar radiographs. Between August 2021 and December 2023 a total of 120 patients were included in the study for analysis, of whom 82 (68.3%) exhibited mild AAC and 38 (31.7%) had moderate-severe AAC. Analyses using the multivariate linear regression model revealed a significant correlation between AAC comorbidity and postoperative clinical outcomes. At 1 year post-surgery, the mean change in leg pain following endoscopic lumbar discectomy was significantly less for patients with moderate-severe AAC (5.0 points) than for patients with mild ACC (p < 0.001). Even after adjusting for relevant confounders, this difference remained significant. Similar results were also observed in the postoperative improvement of back pain, the Oswestry Disability Index score, and the physical functioning, role physical, and bodily pain components of the 36-item Short Form Health Survey questionnaire. There was no significant difference in the rate of repeat surgery or post-surgical new-onset back pain between patients with different levels of severity of AAC at 1 year post-surgery. There is a significant association between the severity of AAC and clinical outcomes among patients with lumbar disk herniation who underwent endoscopic lumbar discectomy. AAC may serve as a prognostic factor in predicting surgical outcomes and guiding management strategies for patients with lumbar disk herniation following endoscopic lumbar discectomy.

Off-Label Bone Morphogenetic Protein 2 Use Results in Successful Posterolateral Lumbar Fusion in a Veteran Population.

Patients within the US Veterans Health Administration (VA) system have higher rates of comorbidities and chronic pain, increasing risks of complications/poor outcomes following spine surgery. Although the use of bone morphogenetic protein 2 (BMP-2) is established for anterior lumbar interbody fusion, its indications for off-label use in posterolateral fusion are unclear. The objective of this study was to evaluate safety and utility of BMP-2 in posterolateral fusion through a 15-year experience at the VA. Patients underwent posterolateral lumbosacral fusions with BMP-2 by a single VA surgeon from January 1, 2005, to January 1, 2020. The primary outcome was fusion assessed through postoperative radiographs. Secondary outcomes included adjacent segment disease (ASD) and postoperative pain clinic utilization. Sixty-eight patients underwent lumbosacral posterolateral fusion with BMP-2; 77.9% were discharged home and had no postoperative complications. All patients achieved bony fusion at a mean of 113.3 ± 59.9 days postoperatively. Five patients were diagnosed with cancer postoperatively, and eight patients required revision for ASD. No notable predictors of ASD exist. Preoperative opioid use predicted postoperative pain clinic utilization. Posterolateral lumbar fusion with BMP-2 in veterans yields high fusion rates and favorable complication profiles and should be considered in multimorbid hosts. Retrospective review of prospectively collected data.

The impact of closed suction wound drainage on chronic pain and health-related quality of life after posterior spinal fusion in patients with adolescent idiopathic scoliosis.

Closed suction subfascial drainage is widely used after instrumented posterior spinal fusion in patients with a spinal deformity. The aim of this study was to determine the effect of this wound drainage on the outcomes in patients with adolescent idiopathic scoliosis (AIS). This was a further analysis of a randomized, multicentre clinical trial reporting on patients after posterior spinal fusion using segmental pedicle screw instrumentation. In this study the incidence of deep surgical site infection (SSI) and chronic postoperative pain at two years' follow-up are reported. We conducted a randomized, multicentre clinical trial on adolescents undergoing posterior spinal fusion for AIS using segmental pedicle screw instrumentation. A total of 90 consecutive patients were randomized into a 'drain' or 'no drain' group at the time of wound closure, using the sealed envelope technique (1:1). The primary outcomes in the initial study were the change in the level of haemoglobin in the blood postoperatively and total blood loss. A secondary outcome was the opioid consumption immediately after surgery. The aim of this further study was to report the rate of deep SSI and persistent postoperative pain, at two years' follow-up. As previously reported, the mean 48-hour opioid consumption was significantly higher in the no drain group (2.0 mg/kg (SD 0.8) vs 1.4 mg/kg (SD 0.7); p = 0.005). There were no delayed deep SSIs. At two years' follow-up, the mean Scoliosis Research Society 24-item questionnaire (SRS-24) total score did not differ between the groups (4.11 (SD 0.47) vs 4.16 (SD 0.33); p = 0.910). The mean SRS-24 pain score was 4.28 (SD 0.48) in the no drain group compared with 4.33 (SD 0.66) in the drain group (p = 0.245). Seven patients (19%) in the no drain group and six in the drain group (14%) reported moderate to severe pain (numerical rating scale ≥ 4) at two years' follow-up (p = 0.484). The general self-image domain score was significantly higher in the no drain group compared with the drain group (4.02 (SD 0.74) vs 4.59 (SD 0.54); p < 0.001). The main finding in this study was that more severe pain immediately after surgery did not result in a higher incidence of chronic pain in the no drain group compared with the drain group. Back pain and health-related quality of life at two years' follow-up did not differ between the groups. The patient-reported self-image domain was significantly better in the no drain group compared with the drain group.

Thyroid Uncomplicated Surgery with Lack Placement of Drains. A Retrospective Analysis.

Thyroid drains after thyroid surgery are often used despite evidence. The aim of this retrospective study was to determine the post-operative complication rates following thyroid uncomplicate surgery without drain. The medical records of two hundred and thirty-nine patients who undergone thyroid surgery without and with drain were reviewed. The rate of post-operative either complications and pain were evaluated. The distribution of the operations performed were similar in two groups, in no-drain group (group A) there were total thyroidectomy 68.7% and lobectomy 31.3% while in drain group (group B) the total thyroidectomy were 70.8% and the lobectomy were 29.2%, this without statistical significant difference. Postoperative complications that occurred included seromas, hematoma and wound infections were without significantly differences. Postoperative pain was significantly lower in group A than in group B at two timepoint. The mean hospital stay was significantly shorter in the non-drained group. The no-drain uncomplicated thyroid surgery was safe and didn't increase a rates of post-operative complications. In addition, we achieved significant reduction of postoperative pain, hospital stay and overall costs.

Comparative study of lidocaine- saline versus saline as washout for lumpectomy cavity on acute postoperative pain

PurposeThis study aimed to evaluate the impact of lidocaine-saline solution compared to saline alone for washing out the lumpectomy cavity, focusing on its effect on acute postoperative pain—a prevalent and significant concern among patients undergoing breast surgery. MethodsIn this comparative study, 72 patients scheduled for lumpectomy surgery were randomly assigned to either the lidocaine-saline or saline group. The lidocaine-saline group was administered a washout of the lumpectomy cavity with 2 % lidocaine at a dosage of 1.75 mg/kg in 0.9 % normal saline, whereas the saline group received a washout with an equivalent volume of 0.9 % normal saline. We recorded the participants' basic characteristics, heart rate, blood pressure, the incidence and intensity of pain (measured by the visual analogue scale), and the usage of postoperative analgesics. ResultsThe two study groups did not differ significantly in their basic characteristics, heart rate and blood pressure. The saline group had significantly higher pain intensity than the lidocaine-saline group at 30 min after surgery (4.61 vs. 2.88, P < 0.0001) and at all other time points (P < 0.001). The saline group also took the first dose of analgesics earlier than the lidocaine-saline (46.66 Vs. 170.55 min, P < 0.001) and used a significantly higher mean dose of meperidine (77.50 mg vs 33.47 mg, P < 0.001). ConclusionThe use of a lidocaine-saline wash during lumpectomy procedures can significantly reduce postoperative pain and lower the necessity for analgesics in patients who have undergone breast surgery.

Pain prevalence rates and the mediating role of negative affect in adults referred to personality disorder treatment: A cross-sectional study

Personality disorders (PDs) are prevalent among individuals with chronic pain, but less is known about the prevalence of pain in the PD population. This study therefore sought to explore the prevalence of current or everyday pain among individuals referred to outpatient PD treatment, and further explore the mediating role of negative affect in the relationship between PD severity and current pain. Data was retrieved from the Norwegian Network for PDs’ quality register which included 4361 participants. Pain was operationalized using the EQ-5D-3L “pain or discomfort” item and four SCL-90-R pain-related items (“pain bothersomeness”). Rates of self-reported pain were explored both pre and post treatment to determine the persistency of the pain-related symptoms. The role of negative affect in the relationship between PD severity and pain was investigated by linear regression analysis. A substantial burden of pain-related symptoms was demonstrated, as 71% and 80% reported moderate to extreme pain or discomfort and pain bothersomeness, respectively. Muscle soreness was the most common pain (59%) followed by headache (48%), low back pain (46%), and heart or chest pain (34%). Moderate to extreme pain or discomfort was persistent for 77% of the participants who provided end of treatment data (mean treatment duration was 82 weeks). Negative affect mediated the relationship between PD severity and pain. To our knowledge, this is the first large-scale study on everyday pain in patients with PDs. The findings reveal that moderate to extreme pain is prevalent among persons with PDs and that this co-occurrence is driven by negative affect. PerspectivePain is a prevalent and potentially underrecognized symptom in personality disorders and persists until treatment termination for a large group of patients. This co-occurrence may be driven by a susceptibility to negative affect that is enhanced by personality disorder features.

Altering prosthetic alignment does not affect hip and low back joint loading during sit-to-stand in people with a transtibial amputation

People with a transtibial amputation (TTA) have greater prevalence of low back and hip joint pain compared to the general population. Altered movement, loading patterns, and neuromuscular activation during daily tasks like sit-to-stand likely contribute to these high rates of pain. In addition, muscle activation, ground reaction forces, and trunk range of motion can be affected by prosthetic alignment during sit-to-stand. However, it is unclear how prosthetic alignment affects joint contact forces during this task. The purpose of this study was to investigate the effect of prosthetic alignment on hip and low-back joint loading in people with TTA during sit-to-stand. Kinematics, ground reaction forces, and muscle activity data were collected from 10 people with TTA and 10 age- and sex- matched individuals without limb loss during five self-paced sit-to-stand trials. Participants with TTA completed the sit-to-stand task with their prescribed alignment and six altered alignment conditions (±10 mm anterior/posterior, medial/lateral, and ± 20 mm short/tall). A musculoskeletal model was used to calculate hip and L4-L5 joint loading. There were no differences in hip or L4-L5 joint loading between alignments. Participants with TTA had a greater peak hip joint contact force on the intact side hip compared to the amputated side hip across all alignments. Participants with TTA had greater L4-L5 joint contact force compared to those without amputation. While prosthetic alignment did not affect joint loading during sit-to-stand, future work on additional dynamic tasks is needed to better understand the potential role of prosthetic alignment on joint loading.

Global Rating of Change for Better or Worse-What Does It Mean When Patients Who Are Treated for Patellofemoral Pain Rate Their Change?

OBJECTIVE: To investigate how a global rating of change (GROC) score corresponds to change in Knee injury and Osteoarthritis Outcome Score (KOOS) subscales in people with patellofemoral pain (PFP). DESIGN: Secondary analysis of data from 3 clinical trials. METHODS: Four hundred ninety adolescents (10-18 years old) and adults (19-40 years old) with PFP completed KOOS (5 subscales, 0-100) at baseline and 3-month follow-up as well as GROC at 3-month follow-up. GROC category descriptors were mapped to 5 categories: worse, no change, a bit better, better, and much better. Gaussian approximation was then used to calculate the change in KOOS scores for each GROC category. RESULTS: Due to overlap between KOOS scores in "no change" and "a bit better," all analyses were performed on 4 categories. For all KOOS subscales, patients who reported being "worse" had negative KOOS scale change scores (≤ -2); patients reporting "no change" had KOOS scale change scores that ranged from -5 to 14; and patients feeling "better" or "much better" had positive KOOS scale change scores that ranged from 4 to 26 and ≥16, respectively. CONCLUSION: When patients with PFP reported feeling "worse," "better," or "much better," there was a small-to-substantial change across the different KOOS scales. This is in contrast to no difference between reporting "a bit better" or "no change" in KOOS. When patients say they feel a little better, clinicians should be less confident about whether change has truly occurred. J Orthop Sports Phys Ther 2024;54(10):657-671.

CONCEPTUAL STUDY ON THE MANAGEMENT OF GRIDHRASI : A REVIEW ARTICLE

The modern lifestyle has given rise to a number of health-related issues. A growing number of musculoskeletal conditions include sciatica. Sciaticas signs and symptoms are similar to those of Gridhrasi, also known as Shoolpradhan Vatavayadhi in Ayurveda. Given that the patients gait resembles that of a vulture (gridhra) and that his legs are inflexible and slightly bowed, the disease may have derived its name from the bird gridhra. According to Sushruta, the kandara of Gridhrasi is impacted by the vitiated Vata dosha, making it difficult for the patient to extend their leg. Sciatica is an extremely painful ailment where pain radiates along the posteriolateral portion of the leg and thigh from the lumbar area. The quality of life is negatively impacted by low back discomfort, especially during ones prime working years. Since over 75% of people worldwide have had low back pain at some point in their lives, the incidence rate of low back pain is noteworthy. It is the most typical illness that keeps people from working. This illness leaves the victim partially disabled since they may not be able to stand, walk, or sit comfortably. The two basic areas of treatment in modern medicine are surgical pathology repair and pain management. The goal of Ayurvedic treatment is to rectify the underlying functional imbalance in order to restore harmony. The goal of Ayurvedic Gridhrasi treatments is to restore the imbalanced Vata or Vata Kapha to health by bringing it back to equilibrium.

Long-term outcomes of avascular necrosis in sickle cell disease using joint-specific patient-reported outcome measures: Results from a multicentre study.

Avascular necrosis (AVN) is a prevalent and progressive complication in young patients with sickle cell disease (SCD), but no study evaluated the long-term subjective and objective outcome measures. Oxford hip score (OHS) and Oxford shoulder scores (OSS) are validated joint-specific patient-reported outcome measures (PROMs). In this prospective multicentre study, 47 SCD patients with pre-existing diagnosis of AVN occurred at a median age of 35.9 (24.2-47.6) filled out the OHS and OSS at median follow-up of 9.4 years (4.5-12.9). No patient died after diagnosis of AVN. Hip AVN was present in 34 (72%) patients, with bilateral involvement in 25 (74%); 26 (59%) underwent total hip arthroplasty (THA) at a median age of 34.6 (22.6-49.5); and 4 (15%) required re-surgery. OHS revealed moderate to severe impairment both in patients underwent THA and no hip surgery. Shoulder AVN was present in 13 (6%) patients and OSS revealed mild to moderate impairment. A high rate of compromised joint function and pain was observed 10 years after diagnosis of AVN regardless of the type of treatment, outlying the need to improve the management of this sickle-related complication. OHS and OSS are validated joint-specific PROMs easy to use in all SCD centres.

Smooth Operator: Nanotextured Breast Tissue Expanders Are Associated with Lower Rates of Capsular Contracture

Background: Continuous research on breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has introduced a focus on surface texturizations and a shift towards smooth breast devices, yet outcomes comparing the complication profiles of differently textured tissue expanders (TEs) remain conflicting. The study aim was to compare the complication profile of a new nanotextured and MRI-compatible TE to micro- and macrotextured TEs and to identify possible predictors for complications. Methods: A retrospective analysis of women undergoing expander-based breast reconstruction after mastectomy between January 2016 and March 2022 was conducted. The primary endpoint was the development of capsular contracture. Possible predictors were analyzed in a mixed-effects model using the least absolute shrinkage and selection operator (LASSO). Moreover, a comparison of complications and an evaluation of predictors were carried out. Results: A total of 147 breasts, encompassing 82 nanotextured, 43 microtextured and 22 macrotextured TEs, were analyzed. Breasts with nanotextured TEs were less likely to develop capsular contracture overall (OR, 0.12; 95%CI 0.05–0.28, p &lt; 0.001). Post-mastectomy radiotherapy (PMRT) was identified as a predictor for capsular contracture (OR, 4.67; 95%CI 1.86–11.71, p &lt; 0.001). Breasts with nanotextured TEs showed a higher rate of seroma, but lower rates of malposition and pain. Predictors for developing postoperative complications included higher mastectomy weight (p = 0.008). Conclusions: Breasts with nanotextured TEs exhibited the lowest rate of capsular contracture compared to micro- and macrotextured TEs. Together with its MRI-compatibility and improved oncologic follow-up, the nanotextured TE seems to be a favorable device for expander-based breast reconstruction.

Examining changes in pain interference via pandemic-induced isolation among patients receiving medication for opioid use disorder: a secondary data analysis

BackgroundEarly in the pandemic, the United States population experienced a sharp rise in the prevalence rates of opioid use, social isolation, and pain interference. Given the high rates of pain reported by patients on medication for opioid use disorder (MOUD), the pandemic presented a unique opportunity to disentangle the relationship between opioid use, pain, and social isolation in this high-risk population. We tested the hypothesis that pandemic-induced isolation would partially mediate change in pain interference levels experienced by patients on MOUD, even when controlling for baseline opioid use. Such work can inform the development of targeted interventions for a vulnerable, underserved population.MethodsAnalyses used data from a cluster randomized trial (N = 188) of patients on MOUD across eight opioid treatment programs. As part of the parent trial, participants provided pre-pandemic data on pain interference, opioid use, and socio-demographic variables. Research staff re-contacted participants between May and June 2020 and 133 participants (71% response rate) consented to complete a supplemental survey that assessed pandemic-induced isolation. Participants then completed a follow-up interview during the pandemic that again assessed pain interference and opioid use. A path model assessed whether pre-pandemic pain interference had an indirect effect on pain interference during the pandemic via pandemic-induced isolation.ResultsConsistent with hypotheses, we found evidence that pandemic-induced isolation partially mediated change in pain interference levels among MOUD patients during the pandemic. Higher levels of pre-pandemic pain interference and opioid use were both significantly associated with higher levels of pandemic-induced isolation. In addition, pre-pandemic pain interference was significantly related to levels of pain interference during the pandemic, and these pain levels were partially explained by the level of pandemic-induced isolation reported.ConclusionsPatients on MOUD with higher use of opioids and higher rates of pain pre-pandemic were more likely to report feeling isolated during COVID-related social distancing and this, in turn, partially explained changes in levels of pain interference. These results highlight social isolation as a key risk factor for patients on MOUD and suggest that interventions promoting social connection could be associated with reduced pain interference, which in turn could improve patient quality of life.Trial registrationNCT03931174 (Registered 04/30/2019).

Doctors’ experience providing primary care for refugee women living with chronic pain: a qualitative study

BackgroundThe experiences of GPs in Australia highlight key considerations regarding workload demands, remuneration incentives and the practical implications of working in regions with high ethnic density. This exploration helps to understand the elements that influence GPs delivery of care, particular for refugee women who exhibit disproportionately higher rates of chronic pain. This qualitative study explored the experiences of GPs providing care for refugee women living with chronic pain.MethodsSemi-structured interviews were undertaken with 10 GPs (9 female and 1 male) practicing across metropolitan Melbourne, Australia. GPs were recruited via purposive sampling and a snowballing strategy. Participants work experience ranged from one to 32 years. Audio recordings of the interviews were transcribed verbatim and stored in qualitative data Nvivo 12 software for coding. Transcripts of interviews were analysed thematically using a phenomenological approach.ResultsThree overarching themes were identified: (1) meeting the needs of refugee women living with chronic pain; (2) the role of the GP; and (3) the challenges of the health care system. These themes reflected the complexity of consultations which arose, in part, from factors such as trust, the competencies of clinician’s and the limitations posed by time, funding and interpreter use.ConclusionGPs acknowledged the uniqueness of refugee women’s chronic pain needs and whilst doctors welcomed care, many were often challenged by the complex nature of consultations. Those that worked in settings that aligned with refugee women’s needs highlighted the importance of cultivating culturally safe clinical environments and listening to their patients’ stories. However, system level challenges such as time, funding and resource constraints created significant challenges for GPs. Exploring GPs experiences allows for a better understanding of how vectors of disadvantage intersect in health care and highlights the need to better support doctors to improve health care provision for refugee women living with chronic pain.

Surgical techniques for ovarian endometriosis

Key content: All patients with ovarian endometriosis should be offered an individualised, shared decision‐making approach informed by clinical history, symptoms and fertility status. Surgical management of ovarian endometriosis can be effective in treating endometriosis‐associated pelvic pain and infertility, but there is no current evidence that surgery for ovarian endometriosis increases the success of in vitro fertilisation (IVF) treatment. Ovarian reserve tests should be considered before any ovarian surgery and can help guide the patient towards the optimal treatment. The Endometriosis Fertility Index should be incorporated into pre‐operative consultations as a validated tool that estimates the likelihood of spontaneous conception following surgical intervention. Surgeons should be trained in different surgical techniques, types of diathermy and haemostatic agents that can minimise the risk of inadvertent injury to normal ovarian cortex. Learning objectives: To facilitate informed decision‐making regarding the treatment of ovarian endometriosis. To gain insight into the possible surgical techniques available to manage ovarian endometriosis and the evidence behind them. To understand the impact of each technique on endometriosis‐associated pain, fertility outcomes and recurrence rates. Ethical considerations: Should fertility preservation be offered to all women of reproductive age with fertility aspirations and a diagnosis of endometriomas? Should integrated care boards (ICBs) devise specific criteria to offer funding for fertility preservation as an option before surgery for ovarian endometriosis?

Pressure Pain Hyperalgesia Expressed by Topographical Pressure Pain Sensitivity after Cardiac Surgery.

We aim to evaluate changes in pressure pain sensitivity before and after cardiac surgery using topographical sensitivity maps utilizing a pressure algometer. Pressure pain thresholds over 17 thoracic points and 4 distant pain-free points were assessed in 70 patients (women: 29, age: 67.5 years), before and at 1, 3, and 7 postoperative days. Thoracic topographical pressure pain sensitivity maps were calculated at all follow-ups. Postoperative pain was recorded at each follow-up on a numerical pain rate scale. Postoperative pain intensity decreased from 6.4 (SD 1.0) on the first postoperative day to 5.5 (SD 1.9) on the third and to 4.5 (SD 1.7) on the seventh day (p < 0.001). The mixed-model ANOVA revealed that the lowest pressure pain thresholds were observed one day after surgery, increased slightly during follow-up, and were lower at the xiphoid process. Significant negative correlations between postoperative pain intensity and pressure pain thresholds were observed at each time point in thoracic measures (all, p < 0.01), but not with pressure pain thresholds from distant pain-free areas. Postoperative pain after cardiac surgery can be objectively quantified using algometry. Pressure pain hyperalgesia was associated with the intensity of postoperative pain.

The effect of music interventions on anxiety, pain, and pregnancy rates in women undergoing fertility treatment before oocyte collection and embryo transfer: Systematic review and meta-analysis of randomized controlled trials

IntrodutionThe present review aimed to evaluate the available evidence in the literature on the effect of music interventions on improving outcomes related to anxiety, pain, and pregnancy rates of women undergoing fertility treatment, prior to oocyte collection and embryo transfer. MethodWe searched the following databases from database inception to 2 May 2024, PUBMED, Embase, Web of Science, and the Turkish Academic Network and Information Center (ULAKBIM). Randomized controlled trials (RCT) in Turkish and English languages were included in the screening. Articles were scanned using MeSH-based keywords. The data were analyzed using the Review Manager computer program (Version 5.4.1). ResultsA total of 8 RCTs, including 1634 female patients, were included in our review. Music interventions significantly reduced anxiety scores prior to oocyte collection or fertilization compared to the control group (Standardised Mean Difference (SMD):0.26, 95 % CI:0.39 to 0.13, Z = 3.91, p < 0.0001). Moreover, after the music treatment, there was a significant improvement in the pain score during the procedure (SMD:0.96, 95 % CI:1.72 to -0.20, Z = 2.49, p = 0.01). Although more women in the music interventions group experienced an increase in the clinical pregnancy rate compared to the control group, there was no evidence of an effect on pregnancy rate (SMD:0.14, 95 % CI:2.63 to 2.34, Z = 0.11, p = 0.91). ConclusionMusic interventions appears to improve anxiety and pain scores in female patients receiving fertility treatment when administered during oocyte collection and fertilization. They may increase the clinical pregnancy rate but this not statistically significant. More research with larger sample sizes is needed to investigate the impact of music interventions on assisted reproductive technology clinical outcomes.

Pooperacinių išvaržų gydymo naudojant tinklelį atokieji (daugiau negu penkerių metų) rezultatai: literatūros apžvalga

Introduction. Postoperative hernias occur in 10–15% of patients. Considering the increase in the incidence of complications with the number of operations it is crucial to choose the optimal surgical technique in order to control the complications rate. This literature review summarizes previous studies on the treatment of postoperative hernias with mesh, comparing complication and recurrence rates according to surgical technique and mesh position. Methods. A thorough search was conducted on the PubMed database to retrieve literature on recurrence, chronic pain, haematoma, seroma, and surgical site infections rates. The results were meticulously summarised and used to confidently compare open and laparoscopic surgical techniques, as well as “sublay” and “onlay/inlay” mesh positions in more than 5-year follow-up. Results. The analysis was conducted on five publications that met the selection criteria. The results showed that laparoscopically treated hernias had lower recurrence and chronic pain rates, but more frequent haematomas. The presence of wound infections, BMI &gt;30, treatment of recurrent postoperative hernias, multiple fascia lesions, enterotomy, larger abdominal wall defect and longer operative time were observed to be associated with higher recurrence rates. The position of the sublay mesh is associated with less frequent seromas, surgical infections, and recurrence compared to the onlay/inlay position. Studies have reported the superiority of large-pore lightweight polypropylene multifilament mesh over the same heavyweight mesh in managing postoperative hernias. Lightweight mesh is linked to a lower risk of hernia recurrence and higher compliance with the abdominal wall. Conclusion. Laparoscopic surgery is associated with lower rates of recurrence and chronic pain, but a higher frequency of haematomas. The sublay mesh position is associated with lower rates of seromas, surgical infections, and recurrence.

Impact of patient's sex on groin hernia repair: A systematic review and meta-analysis.

Groin hernia repair (GHR) is a performed procedure worldwide, with approximately 20million surgeries carried out each year. Despite being less common in females, there is a lack of research on how sex influences the outcomes of GHR. This systematic review and meta-analysis aim to assess how patient sex impacts results in GHR. We performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. We searched for studies up to October 2023 in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. The studies included focused on sex outcomes for both robotic and open GHR procedures. Data extraction and quality assessment were conducted using the Risk of Bias in Non-Randomized Studies - Of Interventionstool. Our statistical analysis was performed using the metafor package in RStudio. After screening a total of 3917 articles, we identified 29 studies that met our criteria, comprising a total of 1,236,694 patients. Among them, 98,641 (7.98%) patients were females. Our findings showed that females had higher rates of hernia recurrence (RR 1.28), chronic pain (RR 1.52), and surgical site infections (SSIs) (RR 1.46) compared to males. Females showed a lower tendency to undergo minimally invasive surgery (MIS) with a relative risk of 0.82 (95% CI 0.69-0.97; p=0.02). Females tend to face higher rates of complications after GHR such as an elevated risk of chronic pain, recurrence, and surgical site infections (SSI). Moreover, they undergo fewer MIS options compared to males. These results underscore the importance of research to enhance outcomes for women undergoing GHR.

The burden of chronic pain in transgender and gender diverse populations: Evidence from a large US clinical database

AbstractBackgroundChronic pain, affecting approximately 20% of the global population, is the leading cause of disability worldwide. Transgender individuals are disproportionately exposed to chronic pain risk factors compared with the cisgender population. This study compares the incidence of chronic pain between transgender and cisgender individuals and examines the impact of gender affirming hormone therapy, anxiety, and depression on chronic pain.MethodsThe study analysed medical records data of 56,470 transgender men and 41,882 transgender women in the TrinetX database. Six cohorts were created: transgender women either receiving oestrogen or no intervention, transgender men receiving testosterone or no intervention and cohorts of cisgender males and females. Unmatched age‐adjusted incidence rates were calculated. Then cohorts were matched on 22 chronic pain‐associated covariates and the rate of new chronic pain diagnoses was compared between those receiving hormone therapy and those without.ResultsWe observed significantly higher rates of chronic pain among transgender individuals compared with cisgender counterparts. Transgender men on testosterone therapy and transgender women on oestrogen therapy exhibited an increased likelihood of chronic pain diagnoses compared with those not receiving hormone therapy. Individuals with anxiety and depression were more likely to be diagnosed with chronic pain.ConclusionThis study demonstrates a significant burden of chronic pain in transgender individuals, with an increased risk among those receiving hormone therapy. Our study, the first to assess chronic pain in a large cohort of transgender patients, provides support for a potential association between hormone therapy and risk of chronic pain diagnosis. Further research is required to understand causal mechanisms and to develop improved screening and management of chronic pain in transgender populations.Significance StatementOur study, featuring the largest cohort of Transgender and Gender Diverse (TGD) individuals assembled to date, reveals critical disparities in chronic pain among TGD populations, notably those on hormone therapy, compared with the cisgender population. It highlights the urgent need for specialized screening and treatment for this vulnerable population, and research into hormone therapy's impact on pain. These insights aim to foster more effective, personalized healthcare, enhancing the well‐being and quality of life for the TGD community.
