(044) AN INNOVATIVE AND NON-INVASIVE METHOD OF REDUCING PAIN UTILIZING VIBRATION DURING IUD INSERTION: PATIENT REACTIONS AND ONE PROVIDER’S APPROACH

Abstract Introduction Pain is commonly experienced during Intrauterine device (IUD) insertion and a possible barrier to this form of contraception. Pharmacological methods and non-pharmacological techniques are available to reduce pain during this procedure, but the efficacy varies on a case-by-case basis and data is conflicting regarding doses. Additional techniques are needed to increase the likelihood of a more patient centered approach to address pain experienced during IUD placement. Objective The purpose of the current project is to describe exploratory use of vibration and propose it as an innovative pain management technique during IUD insertion. Methods Recognizing that the umbilicus and the distal third of the vagina are embryologically connected, the current clinician hypothesized that external vibration applied to the umbilicus by a patient during IUD placement may reduce pain. Starting in 2017 external umbilical vibration was added to a previously established list of pain reduction options available during IUD placement at one clinical practice. Patients were consulted prior to IUD insertion and the list of multiple options discussed as part of regular practice. Patients and the provider determined the methods of pain reduction that best fit the individual patient’s needs based on their previous experiences, apprehension, and other concerns related to the procedure. Clinician observation and recall of response and reactions following the use of vibration will be shared. Results A detailed description of the umbilical vibration technique will be provided. Provider recall and summary of anonymous patient responses will be discussed, as well as the possible implications for gynecological care. Verbal and non-verbal responses from patients who elected to use umbilical vibration, or a combination of umbilical vibration and other techniques, to reduce pain have been overwhelmingly positive. No negative experiences with this non-invasive technique have occurred. Conclusions Umbilical vibration may serve as an effective, low-cost option to reduce pain during IUD placement. Providers considering this technique should be comfortable discussing vibration and open to this type of patient centered care. Umbilical vibration as a pain reduction technique for IUD insertion could be utilized in a trauma informed practice. A more in-depth study to further explore the intricacies of this technique is in preparation. Disclosure No.

(108) ENHANCING PELVIC EXAM COMFORT AND DIAGNOSTIC ACCURACY: REVIEWING THE UTILITY OF NITROUS OXIDE FOR HYPERTONIC PELVIC FLOOR ASSESSMENT

Abstract Introduction Nitrous oxide is an anesthetic, anxiolytic, and analgesic commonly used for general and dental anesthesia, sedation, and severe pain. Studies show that nitrous oxide is also used in several in-office gynecological and urological procedures as a sedative and anxiolytic agent with a safer drug profile than other anesthetic agents. It is also being trialed as a treatment for mood disorders. Nitrous oxide does not render individuals unconscious, making it a more favorable option for stressful and painful medical procedures than general anesthesia because it allows the patient to feel more in control of their body and aware of the proceedings. Objective To analyze the use of in-office nitrous oxide during medical procedures and evaluate its effectiveness in reducing pain and anxiety levels to predict the utility of it during pelvic exams in patients with vestibulodynia. Methods A literature review was performed through the PubMed database between 2007-2022. The authors independently and thoroughly screened abstracts and full-text articles and assessed the relevant medical literature that acknowledged the use of nitrous oxide in in-office medical procedures. Key terms used to refine the search include [“nitrous oxide in medical procedures”], [“nitrous oxide in gynecology”], [“nitrous oxide in urology”]. Results One study explored the use of nitrous oxide during childbirth in women diagnosed with PTSD, and the results were significant for nitrous oxide reducing PTSD symptom severity. Multiple studies suggest the use of nitrous oxide during dental procedures reduces patient anxiety; one specifically measured sixty anxious patients pre- and post-endodontic procedures and noted a significant reduction in anxiety during the procedure with the use of nitrous oxide. Various studies of gynecological and urological procedures report the successful use of nitrous oxide in reducing peri-procedural pain compared to other analgesic alternatives. A common example is its use during intrauterine device insertion, which is correlated with higher patient satisfaction as it decreases pain. Additionally, a study among patients undergoing extracorporeal shockwave lithotripsy found no significant difference between the use of meperidine, an opioid, and nitrous oxide in post-procedural Visual Analog Scale pain scores with no adverse events reported in the nitrous oxide group. Another study revealed that using local anesthesia in transrectal prostate biopsies resulted in some patients experiencing notable anxiety and pain. At the same time, no such relationship was observed among patients who received nitrous oxide before this procedure. Conclusions Vestibulodynia is a subset of genitopelvic pain isolated to the vulvar vestibule. Vestibulodynia has three proposed etiologies: tissue neural proliferation, musculoskeletal, and hormonally mediated. Discriminating these three etiologies can be difficult, especially when a proper pelvic exam cannot be achieved due to patients’ discomfort. The three etiologies are biologically intertwined, often resulting in vestibulodynia patients experiencing pelvic floor hypertonicity without regard to specific etiology. A painful pelvic exam is stressful and often an anxiety-producing experience for patients with pelvic hypertonicity and vulvodynia. Hence, with the data provided, we suspect that nitrous oxide will be a useful treatment option to mitigate these consequences for the patient, with the added benefit of easing the exam for the provider, leading to a more accurate diagnosis.

Design study of a low emittance complex bend achromat lattice

Light sources worldwide have experienced rapid growth in the last decades, pushing toward higher brightness with lower emittance to meet growing demands from the user community. The quest for higher brightness motivates the development of low-emittance ring lattices. At this point, all fourth-generation storage ring light sources employ variations of the multibend achromat (MBA) lattice. In this paper, we discuss an extension of this approach, known as complex bend achromat lattice in relation to the future NSLS-II upgrade. A detailed approach for the lattice design will be described and the developed lattice will be presented. The advantages of using our complex bend approach are evident in reaching a natural emittance as low as 23 pm at a beam energy of 3 GeV, providing a straight section of 8.4 m for long insertion devices, and acquiring a ratio of about 50% of free space with respect to the ring circumference. The design includes the use of permanent magnets largely reducing the need for power supplies. Our new approach provides an extension to the MBA concept for the next-generation light source lattice design. Published by the American Physical Society 2024

An Experimental Study of Incremental Buckling-Resistant Inchworm-Type Insertion of Microwire Neural Electrodes

Abstract Chronically implanting microelectrodes for high-resolution action potential recording is critical for understanding the brain. The smallest and most flexible electrodes, most suitable for chronic recordings, are also the most difficult to insert due to buckling against the thin but hard-to-penetrate brain meninges. To address such implantation challenges without introducing further damage to the brain, this paper presents our design and prototype of an inchworm-type insertion device that conducts a grip-feed-release incremental motion for planar microelectrode insertion. To optimize the operating parameters of the developed inchworm insertion device, experimental studies were conducted on PVC-based brain-mimicking phantom to investigate the effects of (1) incremental insertion depth, (2) inserter drive shaft rotary speed, and (3) the resulting inchworm insertion speed, on the phantom (1) penetration rupture force and (2) dimpling depth at rupture. Analysis showed that all three factors had a statistically significant impact on the rupture force and dimpling depth. A moderate level of the resulting insertion speed yielded the lowest rupture force and dimpling depth at rupture. Low insertion speed levels were associated with higher rupture force while high insertion speeds led to a large variance in dimpling depth and potential insertion failure. To achieve such a moderate insertion speed, it would be preferred for both the incremental insertion depth and the drive shaft rotary speed to be at a moderate level. Such findings lay the foundation for enabling previously impossible buckling-free insertion of miniaturized flexible planar microelectrodes deep into the brain.

Comparison of Baska Mask Versus Endotracheal Tube for General Anesthesia in Laparoscopic Cholecystectomy: A Randomized Controlled Trial

: This study aimed to compare the Baska mask and the endotracheal tube, two devices used to manage patient airways during laparoscopic surgery. Fifty patients undergoing laparoscopic cholecystectomy were randomly assigned to receive either the Baska mask or the endotracheal tube. Data on patients’ demographic and physical status, as well as their heart rate, blood pressure, oxygen level, and ease of device insertion, were collected. The mean BMI for the Baska mask group was 24.68 kg/m² (± 4), and for the Endotracheal tube group, it was 24.83 kg/m² (± 4.14), showing no significant difference (P = 0.9768). However, significant differences were observed in hemodynamic parameters. Patients in the endotracheal tube group exhibited higher heart rates, blood pressure, and mean arterial pressure, indicating more cardiovascular stress than those in the Baska mask group. The endotracheal tube also caused more throat irritation, with more patients reporting post-surgery sore throat. The Baska mask was found to be easier and quicker to insert, requiring less skill and time. Both devices provided adequate oxygenation, but the endotracheal tube had more negative effects on the cardiovascular system and throat. In conclusion, the Baska mask could be a better alternative for laparoscopic surgery, improving both physiological parameters and patient comfort.

Vibratory insertion of press-fit acetabular components requires less force than a single blow technique.

Periprosthetic fracture and implant loosening are two of the major reasons for revision surgery of cementless implants. Optimal implant fixation with minimal bone damage is challenging in this procedure. This pilot study investigates whether vibratory implant insertion is gentler compared to consecutive single blows for acetabular component implantation in a surrogate polyurethane (PU) model. Acetabular components (cups) were implanted into 1 mm nominal under-sized cavities in PU foams (15 and 30 per cubic foot (PCF)) using a vibratory implant insertion device and an automated impaction device for single blows. The impaction force, remaining polar gap, and lever-out moment were measured and compared between the impaction methods. Impaction force was reduced by 89% and 53% for vibratory insertion in 15 and 30 PCF foams, respectively. Both methods positioned the component with polar gaps under 2 mm in 15 PCF foam. However, in 30 PCF foam, the vibratory insertion resulted in a clinically undesirable polar gap of over 2 mm. A higher lever-out moment was achieved with the consecutive single blow insertion by 42% in 15 PCF and 2.7 times higher in 30 PCF foam. Vibratory implant insertion may lower periprosthetic fracture risk by reducing impaction forces, particularly in low-quality bone. Achieving implant seating using vibratory insertion requires adjustment of the nominal press-fit, especially in denser bone. Further preclinical testing on real bone tissue is necessary to assess whether its viscoelasticity in combination with an adjusted press-fit can compensate for the reduced primary stability after vibratory insertion observed in this study.

Women's experiences with the post-placental intrauterine device: a qualitative study.

To explore women's experiences with postpartum intrauterine device (PPIUD) insertion and the decision-making process in the postpartum period. A qualitative design was employed with face-to-face interviews using a semi-structured script of open questions. The sample was intentionally selected using the concept of theoretical information saturation. Interviews were conducted (1) in the immediate postpartum period, and (2) in the postpartum appointment. 25 women (N = 25) over 18 years old who had a birth followed by PPIUD insertion were interviewed between October 2021 and June 2022. Three categories were constructed: (1) Choice process, (2) Relationship with the health team at the time of birth and the postpartum period, and (3) To know or not to know about contraception, that is the question. Professionals' communication management, popular knowledge, advantages of the PPIUD and the moment PPIUD is offered play a fundamental role in the construction of knowledge about the IUD. Choice process did not end in the insertion.

Effect of vagus nerve stimulation on emergency department utilization in children with drug-resistant epilepsy: a retrospective cohort study.

Epilepsy affects approximately 470,000 children in the United States. The estimated median incidence is 50.4 cases per 100,000 persons per year. There are approximately 3.1 million seizure-related emergency department (ED) visits per year among children. Vagus nerve stimulation (VNS) is a treatment option for drug-resistant epilepsy (DRE). While its primary goal is to decrease seizure burden, VNS may decrease seizure intensity and improve quality of life. The authors assessed whether VNS decreased the number of seizure-related ED visits in a cohort of children with DRE. The authors performed a retrospective chart review of pediatric patients (aged 0-21 years) who underwent implantation of a vagus nerve stimulator between January 2009 and January 2020 at the University of Pittsburgh Medical Center Children's Hospital of Pittsburgh. They used paired t-tests to assess differences in the number of ED visits 2 years before versus 2 years after VNS device implantation. Univariable linear regression analyses were used to test associations of preoperative characteristics with change in the number of ED visits following vagus nerve stimulator insertion. This study included 240 patients. Compared with patients without seizure-related ED visits before VNS, patients with ≥ 1 ED visits were younger in age at first VNS surgery (9.5 vs 10.8 years), had a shorter epilepsy duration before VNS surgery (5.8 vs 7.4 years), had a later year of device implantation (2014 vs 2012), and on average took more antiseizure medications (ASMs; 2.4 vs 2.1). There was no significant difference between the total number of seizure-related ED visits pre- versus post-VNS surgery (1.72 vs 1.59, p = 0.50), and no difference in status epilepticus-related visits (0.59 vs 0.46, p = 0.17). Univariable linear regression analyses revealed a mean change in ED visits of +0.3 for each year prior to 2022 and -0.5 for each additional ASM that patients took before vagus nerve stimulator insertion. This single-institution analysis demonstrated no significant change in the number of seizure-related ED visits within 2 years following VNS device implantation. Earlier VNS surgery was associated with more seizure-related ED visits after device insertion, suggesting that medical management and center experience may play a role in decreasing seizure-related ED visits. A greater number of ASMs was associated with fewer seizure-related ED visits after VNS device insertion, suggesting the role of medical management, patient baseline seizure threshold, and caregiver comfort with at-home seizure management.

Human Applications of the Anstadt Cup: Implications for Non–Blood-Contacting Biventricular Support

BackgroundDirect mechanical ventricular actuation (DMVA) with the Anstadt cup is effective for non–blood-contacting biventricular support. Pneumatic regulation of a silicone device augments ventricular pump function. Vacuum attachment facilitates diastolic augmentation critical for biventricular support. This report reviews outcomes in patients supported for bridge to transplantation. MethodsDMVA was approved by the institutional review board at Duke University for refractory cardiogenic shock in potential candidates for heart transplantation. Devices with silicone membranes were controlled by pneumatic drive systems. Explanted hearts underwent extensive histologic examination. ResultsFive patients met inclusion criteria. All exhibited immediate return of physiologic pulsatile flow and reduced pulmonary pressures during device insertion. Vasopressors, inotropes, and balloon pump support were discontinued at implantation or within 48 hours. Installation through left thoracotomy (n = 4) took <5 minutes. Postcardiotomy support (n = 1) enabled routine decannulation. Support ranged from 2 to 84 days. Long-term survivors (n = 2) received 2 days of DMVA bridging to heart transplantation and 7.5 days of DMVA for acute myocarditis. There were no device-related complications. An expert cardiovascular pathologist found no evidence of device-related myocardial trauma or injury (n = 4) and no adverse effects on bypass grafts (n = 1). Recovery was deemed futile (n = 3) after diffuse cerebral emboli from prior aortic cross-clamp and extended cardiopulmonary resuscitation and for preexisting sepsis leading to end-organ failure. ConclusionsDMVA with the Anstadt cup effectively supported the failing or arrested heart in humans without adverse cardiac effects. Unique diastolic augmentation, return of physiologic pulsatile flow, and no blood contact contribute to device efficacy.

Assessing the Accuracy and Safety Thresholds of Patient-Specific Screw Guide Template System in Cervical and Thoracic Spine Surgeries Using DAST Measurements.

To analyze the reliability of the newly developed patient-specific Screw Guide Template (SGT) system as an intraoperative navigation device for spinal screw insertion. We attempted to place 428 screws for 51 patients. The accuracy of the screw track was assessed by deviation of the screw axis from the preplanned trajectory on postoperative CT. The safety of the screw insertion was evaluated by the bone breach of the screw. The bone diameter available for screw trajectory (DAST) was measured, and the relations to the bone breach were analyzed. In the inserted screws, 98.4% were defined as accurate, and 94.6% were contained in the target bone. In the cervical spine, the screw deviation between breaching (0.57 mm) and contained screws (0.43 mm) did not significantly differ, whereas DAST for breaching screws (3.62 mm) was significantly smaller than contained screws (5.33 mm) (p<0.001). Cervical screws with ≥4.0 mm DAST showed a significantly lower incidence of bone breach (0.4%) than ≤3.9 mm DAST (28.3%) (p<0.001). In the thoracic spine, screw deviation and DAST had significant differences between breaching (1.54 mm, 4.41 mm) and contained (0.75 mm, 6.07 mm) (p<0.001). The incidence of the breach was significantly lower in thoracic screws with ≥5.0 mm (1.9%) than ≤4.9 (21.9%) DAST (p<0.001). This study demonstrated that our SGT system could support precise screw insertion for 98.4% accuracy and 94.6% safety. DAST was recommended to be ≥4.0 and ≥5.0 mm in the cervical and thoracic spines for safe screw insertion.

In-hospital outcomes in metabolically healthy and unhealthy individuals over 65 years of age with obesity undergoing percutaneous intervention for acute coronary syndrome: A nationwide propensity-matched analysis (2016–2020)

BackgroundThe obesity paradox in patients with coronary artery disease is well established, but the role of the metabolic syndrome associated with obesity is not well studied. Our study aims to evaluate the in-hospital outcomes of percutaneous coronary intervention (PCI) in metabolically healthy individuals with obesity (MHO) and metabolically unhealthy (MUHO) individuals with obesity over 65 years of age with acute coronary syndrome (ACS) between 2016 and 2020. MethodsThis was a retrospective and observational study. Patients were identified through utilizing the National Inpatient Sample (NIS) Database (2016–2020) and ICD-10 codes. By employing a t-test and Pearson's Chi-square test, we assessed and contrasted the initial attributes, concurrent conditions, and results pertaining to all-cause mortality (ACM), cardiogenic shock (CS), length of stay (LOS), and hospitalization expense. Moreover, propensity score matching was conducted in a 1:1 ratio with respect to age, gender, and race. We also utilized multivariable logistic regression to compare MHO and MUHO in terms of the impact on all-cause mortality. ResultsOut of a total of 135,395 patients identified, 2995 patients with MUHO were matched with 2995 MHO patients. Patients in the MUHO group had a higher prevalence of chronic pulmonary disease (24.9 % vs. 19.5 %), peripheral vascular disease (9.3 % vs. 6.7 %), hypothyroidism (16 % vs. 11.5 %), prior myocardial infarction (15.9 % vs. 6.2 %), and prior stroke (7.5 % vs. 2.8 %). Patients in the MHO group had a higher ACM (12.4 % vs. 2.8 %, p < 0.001), CS (18.55 % vs. 7 %, p < 0.001), stroke (2.2 % vs. 1 %, p < 0.001), ventricular assist device insertions (5.2 % vs. 2.7 %, p < 0.001), and IABP insertions (8.8 % vs. 3.8 %) compared to the MUHO cohort. ConclusionOur study revealed an obesity paradox in individuals over 65 years of age undergoing PCI demonstrating worse outcomes, including higher in-hospital mortality, CS, stroke, Ventricular assist device and IABP insertion in MHO patients compared to the MUHO cohort.

Central venous accesses in prone position during the pandemic period: A narrative review.

The unprecedented challenges posed by the global COVID-19 pandemic have magnified the significance of managing intensive care patients in prone positions, particularly those requiring mechanical ventilation. Central venous access is crucial for delivering essential therapies to patients, particularly in intensive care settings. However, the shift in patient management during the pandemic, necessitating prone positioning for improved oxygenation, presented unique hurdles in maintaining and establishing central venous access. Before the pandemic, scant literature detailed the insertion of vascular access devices in prone or unconventional positions. Limited case reports and letters highlighted the feasibility of procedures like ultrasound-guided central catheter placement in patients undergoing surgery or with specific clinical needs. During the pandemic, a surge in case reports and series illuminated the complexities faced by clinicians in maintaining vascular access during pronation procedures. These reports delineated critical scenarios, ranging from rapid clinical deterioration necessitating immediate interventions to challenges with vascular access device (VAD) malfunctions or misplacements during prone maneuvers. Patient selection and device types emerged as critical considerations. Various scenarios, including patients transitioning to prone position from non-invasive ventilation and those requiring additional access for therapies like dialysis, posed challenges in device selection and placement. Successful VAD insertion techniques in prone patients encompassed multiple anatomical sites, including the internal jugular, brachial, femoral, and popliteal veins. However, challenges persisted, particularly with respect to anatomical variations and technical complexities in cannulation. Further research, standardized protocols, and randomized studies are needed to refine and validate the proposed strategies in both pandemic and non-pandemic settings.

Systematic review and network meta-analysis of hydrosalpinx treatment before in vitro fertilization.

To compare different methods to treat hydrosalpinx, based on both ablative and non-ablative approaches, in infertile patients before undergoing IVF-ET. Systematic review and network meta-analysis (NMA) of comparisons between different treatments of hydrosalpinx in infertile patients undergoing IVF. structured searches in common citation databases. Study inclusion criteria: peer-reviewed randomized trials (RCT) or cohort studies comparing effects of salpingectomy, laparoscopic proximal tubal occlusion (LTO), insertion of intratubal device (ITD), sclerotherapy, ultrasound-guided aspiration and no treatment, on live birth, ongoing pregnancy, clinical pregnancy as main outcomes, considering also miscarriage, ectopic pregnancy and complications as secondary outcomes. Principal NMA included RCT, and aggregated NMA of RCT and observational studies was carried out. Pooled effects have been estimated by Odds Ratio (OR) and its 95% confidence interval (CI) for direct and indirect-mixed comparisons, derived from random-effects models. Imprecision and heterogeneity of NMA estimations was assessed by comparison of its 95% CI with predefined intervals for clinically relevant size of effect (OR <0.9 or >1.1). Surface under the cumulative ranking curve (SUCRA) were used to predict treatment rankings for each outcome. Nine RCT were included in main analysis, plus 17 additional observational studies in additional analysis. NMA of RCT did not identify significant differences in the effect of compared treatments on live birth rate, and LTO was the option with the highest value of SUCRA (0.92, mean rank: 1.2). Salpingectomy and US-aspiration associated to a significant increase of ongoing pregnancy rate compared to no treatment, according to NMA results (NMA OR: 4.35; 95% CI: 1.7, 11.14 and 2.8; 95% CI: 1.03, 7.58 respectively). Salpingectomy had the highest SUCRA value (0.88, mean rank: 1.4). NMA estimated significant increase of clinical pregnancy rate for salpingectomy compared with no treatment (NMA OR: 2.24; 95% CI: 1.3, 3.86) as well as for LTO versus no treatment (NMA OR: 2.55; 95% CI: 1.2, 5.41). Both comparisons were affected by a high grade of heterogeneity. For clinical pregnancy, LTO was the intervention with highest SUCRA (0.85; mean rank: 1.6). Regarding secondary outcomes, feasible NMA estimates did not support significant differences between treatments effects. According to aggregated NMA including randomized and observational studies, sclerotherapy showed significant beneficial effects on live birth rate compared to no treatment (NMA (OR: 4.6; 95% CI: 1.21, 17.46). Compared with untreated patients, the aggregated NMA estimates a higher ongoing pregnancy rate in patients treated with salpingectomy (NMA OR: 3.35; 95% CI: 2.12, 5.12), US-aspiration (NMA OR: 2.16; 95% CI: 1.28, 3.65) and LTO (NMA OR: 2.46; 95% CI: 1.11, 5.43). Salpingectomy and LTO produced a higher beneficial effect compared to ITD, based on both direct and indirect comparisons. Salpingectomy obtained the highest SUCRA value in rank of effects on ongoing pregnancy (0.94; mean rank: 1.2). NMA found significant effects on clinical pregnancy for comparisons between the different active management procedures compared with no treatments, with the exception of ITD insertion. LTO had more increasing effect on clinical pregnancy rate compared with US-aspiration (NMA OR: 2.04; 95% CI: 1.05, 3.97), while for the rest of the comparisons between procedures no significant differences were identified. NMA ranked LTO as the treatment with a highest SUCRA value (0.91; mean rank: 1.5). NMA prediction models identified LTO as best intervention to reduce miscarriage (SUCRA value: 0.84; mean rank: 1.8), as sclerotherapy as safer option in terms of ovarian response to IVF stimulation. The present NMA fails to support the effectiveness of any option to treat hydrosalpinx before IVF in order to improve live birth rates, although the beneficial effect of salpingectomy and US aspirations on ongoing pregnancy rates and of both salpingectomy and LTO on clinical pregnancy rates emerges from our analysis, which reinforces current recommendations. Based on the aggregated analyses, sclerotherapy could be a promising alternative to conventional laparoscopic techniques, combined with a favorable safety profile.

Early Single-Center Experience of DaVinci® Single-Port (SP) Robotic Surgery in Colorectal Patients.

Background: DaVinci® single-port (SP) robotic surgery offers several benefits compared to traditional multiport laparoscopic or robotic surgeries. One of the main advantages is that it allows for a minimally invasive approach, resulting in a single, smaller incision and reduced trauma to the patient's body, leading to less postoperative pain, faster recovery, and reduced risk of complications. The cosmesis of a single port with minimal visible scarring is also an attractive aspect to the patients; however, many surgeons use an additional port for energy device, stapler use, and drain insertion. Pure single-port surgery with one incision is still rare. Here, we share our experience of our first 10 cases using the SP robotic platform in colorectal surgery. Methods: From May 2023 to December 2023, colorectal patients who underwent SP robotic surgery were analyzed. Placement of the incision was the umbilicus for eight patients, and right lower quadrant for two patients, through which ileostomy maturation was performed. Data on perioperative parameters and postoperative outcomes were analyzed, with a median follow-up of 4.6 months (range 0.6-7.4 months). Results: A total of 10 colorectal patients underwent DaVinci® single-port robotic colorectal surgery at our institution during this period. The patient demographic was four males (40%) and six females (60%) with a median age of 63.5 years (range 50-75 years). Median body mass index (BMI) was 22.89 kg/m2 (range 19.92-26.84 kg/m2). Nine patients were diagnosed with colorectal cancer, and one patient was diagnosed with a rectal gastrointestinal tumor. One patient underwent anterior resection and cholecystectomy simultaneously. Mean operation time was 222 min (range 142-316 min), and mean wound size was 3.25 cm (range 2.5-4.5 cm). Nine patients underwent surgery with single incision through which a single-port trocar was inserted, and one patient had one additional port for drain insertion. Mean hospital stay was 6 days (range 4-8 days) with one postoperative complication of bleeding requiring transfusion, but there was no readmission within 30 days. Conclusions: Overall, our experience with single-port robotic colorectal surgery has been promising. With only one patient with additional port for drain insertion, all nine patients underwent SP-robotic surgery with single incision for colon as well as rectal surgeries. Compared to an average postoperative length of stay of 6.5-8 days in laparoscopic colorectal surgeries reported in literature, SP-robotic surgery 33showed faster recovery of 6 days highlighting its benefits in patient recovery and satisfaction.

IATROGENIC ACUTE MITRAL INSUFFICIENCY FOLLOWING IMPELLA–ASSISTED INTERVENTIONAL PROCEDURE

Abstract Background Short–term left ventricle mechanical assistance device could be useful in assist interventional cardiologist during high–risk procedures. Abiomed Impella is one of the most frequently used device in this respect due to the high flow available with a low rate of reported complications. Here we report a rare but potentially catastrophic complication related to the Impella device. Case Description A 78 years old patient was referred to our Division by a peripheral hospital for a severe, symptomatic (NYHA III) mitral regurgitation (MR) due to posterior mitral leaflet prolapse (with focal eversion of P3) and chordal rupture (Fig 1a). Medical history included a previous admission in the some hospital due to a scheduled Impella–assisted PTCA (left main/left anterior descending artery) . Pre–procedural trans–thoracic ECHO (TTE) did not show significant MR (Fig 1b). Results Patient underwent urgent surgical procedure. At operation postero–medial mitral commissure was seen to be completely everted with multiple rupture of P3 and A3 chordae. Surgical procedure (Fig 1c) included: P3 plication + posterior–medial commissure edge–to–edge plasty + complete mitral semi–rigid ring (Simulus) n.30. Left atrial appendage was also closed using an external Atriclip. Postoperative course was without significant complications except a superficial wound dehiscence which delayed hospital discharge till 20th postoperative day. Conclusion Despite being a feasible and attractive option for short–term mechanical circulation assistance during high–risk interventional procedure, Impella device insertion could cause significant mitral valve damage leading to clinical deterioration. Such potentially catastrophic complication should be, therefore, mandatory excluded before patient discharge following interventional procedure.

Subchondral cystic lesions of distal phalanx in young and mature horses: A new surgical option

SummaryBackgroundThe outcome of conservative treatment for subchondral cystic lesions (SCLs) of the distal phalanx may be poor, and surgical approach through the hoof may be challenging.ObjectivesTo describe the use of an absorbable device to treat SCLs of the distal phalanx, regardless of cyst location, that eliminates lameness and stimulates bone healing in both young and mature horses.Study designClinical case series.MethodsFive young horses and five mature horses presented with an SCL of the distal phalanx causing lameness. Only rest and medical treatment were previously attempted. An absorbable screw was inserted in all horses after transcortical debridement of the SCL. Follow‐up data were obtained from the official electronic database.ResultsAll horses returned to athletic activity after surgical treatment. In two patients, surgical complication was recorded.Main limitationsThe low number of patients, the need for dedicated instruments and the lack of familiarity with the use of absorbable devices to perform surgical procedures.ConclusionsThe insertion of an absorbable device can be considered a valid surgical option for treating subchondral cystic lesions of the distal phalanx.

The Impact of Enterococcus spp. in the Immunocompromised Host: A Comprehensive Review.

The immunocompromised host is usually vulnerable to infectious diseases due to broad-spectrum treatments and immunological dysregulation. The Enterococcus genus consists of normal gut commensals, which acquire a leading role in infective processes among individuals with compromised immune systems. These microorganisms may express a potential virulence and resistance spectrum, enabling their function as severe pathogens. The Enterococcus spp. infections in immunocompromised hosts appear to be difficult to resolve due to the immunological response impairment and the possibility of facing antimicrobial-resistant strains. As regards the related risk factors, several data demonstrated that prior antibiotic exposure, medical device insertion, prolonged hospitalization and surgical interventions may lead to Enterococcus overgrowth, antibiotic resistance and spread among critical healthcare settings. Herein, we present a comprehensive review of Enterococcus spp. in the immunocompromised host, summarizing the available knowledge about virulence factors, antimicrobial-resistance mechanisms and host-pathogen interaction. The review ultimately yearns for more substantial support to further investigations about enterococcal infections and immunocompromised host response.

A mandibular advancement device attenuates the abnormal morphology and function of mitochondria from the genioglossus in obstructive sleep apnea-hypopnea syndrome rabbits.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a serious and potentially life-threatening disease. Mandibular advancement device (MAD) has the characteristics of non-invasive, comfortable, portable and low-cost, making it the preferred treatment for mild-to-moderate OSAHS. Our previous studies found that abnormal contractility and fibre type distribution of the genioglossus could be caused by OSAHS. However, whether the mitochondria participate in these tissue changes is unclear. The effect of MAD treatment on the mitochondria of the genioglossus in OSAHS is also uncertain. To examine the morphology and function of mitochondria from the genioglossus in a rabbit model of obstructive sleep apnea-hypopnea syndrome (OSAHS), as well as these factors after insertion of a mandibular advancement device (MAD). Thirty male New Zealand white rabbits were randomised into three groups: control, OSAHS and MAD, with 10 rabbits in each group. Animals in Group OSAHS and Group MAD were induced to develop OSAHS by injection of gel into the submucosal muscular layer of the soft palate. The rabbits in Group MAD were fitted with a MAD. The animals in the control group were not treated. Further, polysomnography (PSG) and cone-beam computed tomography (CBCT) scan were used to measure MAD effectiveness. CBCT of the upper airway and PSG suggested that MAD was effective. Rabbits in the three groups were induced to sleep for 4-6 h per day for eight consecutive weeks. The genioglossus was harvested and detected by optical microscopy and transmission electron microscopy. The mitochondrial membrane potential was determined by laser confocal microscopy and flow cytometry. Mitochondrial complex I and IV activities were detected by mitochondrial complex assay kits. OSAHS-like symptoms were induced successfully in Group OSAHS and rescued by MAD treatment. The relative values of the mitochondrial membrane potential, mitochondrial complex I activity and complex IV activity were significantly lower in Group OSAHS than in the control group; however, there was no significant difference between Group MAD and the control group. The OSAHS-induced injury and the dysfunctional mitochondria of the genioglossus muscle were reduced by MAD treatment. Damaged mitochondrial structure and function were induced by OSAHS and could be attenuated by MAD treatment.

Empowering Patients: The Role of Education in Pain Alleviation during IUD Insertion

The discomfort and apprehension associated with the Intrauterine Device (IUD) insertion procedure presents a challenge to its widespread acceptance as a contraceptive modality, notwithstanding its established efficacy. Healthcare providers play a pivotal role in addressing this challenge through the provision of comprehensive educational interventions targeting young women regarding the intricacies of IUD insertion. Such proactive educational endeavors hold promise in fostering heightened acceptance and utilization of the IUD, thereby reducing the rates of unintended pregnancies. This paper delineates strategic interventions aimed at fostering IUD adoption, bolstered by empirical evidence attesting to its efficacy in curbing rates of unplanned pregnancies, childbirths, and induced abortions, particularly within the demographic of young women.

Risk of deep venous thrombosis associated with peripherally inserted central catheter: A retrospective cohort study of 11.588 catheters in Brazil.

Deep Venous Thrombosis (DVT) due to Peripherally Inserted Central Catheter (PICC) is one of the most threatening complications after device insertion. To assess the rate of PICC-associated DVT and analyze the risk factors associated with this event in cancer and critically ill patients. We conducted a descriptive, retrospective cohort study with 11,588 PICCs from December 2014 to December 2019. Patients ≥ 18 years receiving a PICC were included. Pre-and post-puncture variables were collected and a logistic regression was used to identify the independent factors associated with the risk of DVT. The DVT prevalence was 1.8% (n = 213). The median length of PICC use was 15.3 days. The median age was 75 years (18; 107) and 52% were men, 53.5% were critically ill and 29.1% oncological patients. The most common indications for PICC's were intravenous antibiotics (79.1%). Notably, 91.5% of PICC showed a catheter-to-vein ratio of no more than 33%. The tip location method with intracavitary electrocardiogram was used in 43%. Most catheters (67.9%) were electively removed at the end of intravenous therapy. After adjusting for cancer profile ou chemotherapy, regression anaysis revealed that age (OR 1.011; 95% CI 1.002-1.020), previous DVT (OR 1.96; 95% CI 1.12-3.44) and obstruction of the device (OR 1.60; 95% CI 1.05-2.42) were independent factors associated with PICC-associated DVT, whereas the use of an anticoagulant regimen was a protective variable (OR 0.73; 95% CI 0.54-0.99). PICC is a safe and suitable intravenous device for medium and long-term therapy, with low rates of DVT even in a cohort of critically ill and cancer patients.
