Femoral alloprosthesis in bone defect of 30 cm as extremity salvage.

Defects in femoral bone segments represent a reconstructive challenge; they are caused secondary to multiple and extensive debridement in cases of patients with infections, tumors or high-energy trauma. Different treatments have been proposed to address this problem, however, these are limited when it comes to large defects that generate instability of the implants in the native bone as well as loss of functionality and length of the extremities. In the proximal femur, allograft prosthesis composites have been described in the management of extensive tumor resections, but they are not yet widely used in the management of bone defects due to osteomyelitis. The case of a 51-year-old male patient with post-traumatic pan-osteomyelitis of the femur Cierny-Mader IV with a 30-centimeter defect in whom limb salvage was achieved through the application of a femoral alloprosthesis is presented, exhibiting this surgical technique as an alternative in ample resections secondary to infectious processes in young patients, furthermore, offering a solution to the shortage of some prosthetic components in our surrounding.

Various Laparoscopic Techniques in Pelvic Organ Prolapse Surgery.

In the past, transvaginal surgery, native tissue restoration, or obliterative methods have been used in the majority of pelvic organ prolapse (POP) surgeries. Since laparoscopy has gained popularity, other procedures have been created to provide additional POP repair alternatives. Laparoscopic technique offers many advantages compared to open or transvaginal surgery when it comes to anatomical and surgical outcomes, recurrence rates, and patient's acceptance. Furthermore, we encouraged incorporating different laparoscopic techniques into urogynecology training to attract young gynecologists. Based on our own clinical and surgical experience, we present various laparoscopic techniques for treating POP. We think that by giving patients a variety of surgical alternatives, we can treat them all more effectively.

Improvement in Quality of Life after Laparoscopic or Robotic-assisted Sacrocolpopexy with a Single Anterior Mesh in Patients with Pelvic Organ Prolapse: A Retrospective Analysis from a Single Institution.

Objectives: Pelvic organ prolapse (POP) is a significant health-care problem for older women. We have treated POP surgically using laparoscopic sacrocolpopexy (LSC) or robotic-assisted sacrocolpopexy (RSC). The original LSC and RSC procedures were done with anterior and posterior meshes; however, the use of the single mesh procedure is increasing because of its simplicity and safety. There have been few reports about the change in quality of life (QOL) using the single mesh procedure. Therefore, the present study aimed to retrospectively evaluate the change in QOL by LSC and RSC using a single anterior mesh for women without posterior compartment prolapse. Materials and Methods: We performed LSC or RSC using a single anterior mesh in 52 patients who had POP without posterior vaginal wall prolapse between August 2018 and October 2022. We assessed the QOL before and after surgery using prolapse-QOL (P-QOL) questionnaires. Results: All patients who received LSC or RSC with a single anterior mesh left the hospital as scheduled without severe perioperative complications. There were no instances of wound infection or vaginal mesh extrusion. The recovery rate of questionnaires was 63.5% (33/52). All QOL score domains improved significantly, and there were no questionnaire parameters that worsened. Conclusion: LSC or RSC using only a single anterior mesh improves P-QOL with a low incidence of surgical complications for POP patients who did not have posterior vaginal wall prolapse. LSC or RSC with a single anterior mesh may be a prospective new procedure for POP.

Foregut Erosion Related to Biomedical Implants: A Scoping Review.

Introduction: Biomedical devices implanted transabdominally have gained popularity over the past 50 years in the treatment of gastroesophageal reflux disease, paraesophageal hiatal hernia, and morbid obesity. Device-related foregut erosions (FEs) represent a challenging event that demands special attention owing to the potential of severe postoperative complications and death. Purpose: The aim was to provide an overview of full-thickness foregut injury leading to erosion associated with four types of biomedical devices. Methods: The study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). PubMed, EMBASE, and Web of Science databases were queried until December 31, 2023. Eligible studies included all articles reporting data, management, and outcomes on device-related FE. Results: Overall, 132 articless were included for a total of 1292 patients suffering from device-related FE. Four different devices were included: the Angelchik antireflux prosthesis (AAP) (n = 25), nonabsorbable mesh for crural repair (n = 60), adjustable gastric banding (n = 1156), and magnetic sphincter augmentation device (n = 51). The elapsed time from device implant to erosion ranged from 1 to 480 months. Most commonly reported symptoms were dysphagia and epigastric pain, while acute presentation was reported rarely and mainly for gastric banding. The technique for device removal evolved from more invasive open approaches toward minimally invasive and endoscopic techniques. Esophagectomy and gastrectomy were mostly reported for nonabsorbable mesh FE. Overall mortality was .17%. Conclusions: Device-related FE is rare but may occur many years after AAP, nonabsorbable mesh, adjustable gastric banding, and magnetic sphincter augmentation implant. FE-related mortality is infrequent, however, increased postoperative morbidity and the need for esophagogastric resection were observed for nonabsorbable mesh-reinforced cruroplasty.

Management of a Large Abdominal Desmoid Tumor Complicated by Lymphedema of the Lower Limb: A Case Report.

Desmoid tumors, while generally benign histologically, can exhibit locally aggressive behavior, especially when located in the anterior abdominal wall. This case report explores the management of a rare giant desmoid tumor complicated by concurrent lymphedema, emphasizing the nuances of diagnosis, treatment decisions, and their impact on the patient's quality of life. The patient, a 55-year-old obese individual with a BMI of 47, presented with a 25 cm mass in the right paraumbilical region, alongside significant lymphedema in the right lower limb and associated inguinal lymphadenopathy. Abdominal CT revealed a well-defined soft tissue mass in the right paramedian hypogastric region, suggestive of a desmoid tumor. Surgical intervention involved a monobloc resection of the mass with a 5 cm lateral margin, including the right rectus abdominis muscle and associated aponeuroses, and subsequent reconstruction using a biface intraperitoneal synthetic mesh. Postoperative recovery was marked by the resolution of lymphedema and a return to full function of the affected limb. Histopathological examination confirmed the diagnosis of a desmoid tumor. This case underscores the importance of radical surgical resection with adequate margins and appropriate reconstruction to achieve favorable long-term outcomes. The report provides insights for future research and therapeutic advancements in the management of desmoid tumors.

Working in smaller teams in community midwifery practices to foster continuity of carer: Midwives' experiences - A qualitative study in the Netherlands.

BACKGROUND: Midwife-led continuity of carer (MLCC) improves health outcomes and increases pregnant women's satisfaction. Working in smaller teams in community midwifery practices is one of the ways to promote continuity of carer. AIM: To gain insight into the experiences of Dutch community midwives regarding working in smaller teams, by identifying motivators and barriers. METHODS: A qualitative study was conducted using individual, semi-structured interviews (n=9). The sample was purposively selected. The interviews were analysed using the Abbreviated Grounded Theory. FINDINGS: Four themes were identified: 1) Ideal implementation of working in smaller teams, 2) Best care for pregnant women, 3) Conflicts with the current maternity care system, 4) Personal interests of the midwife. The core concept connecting all themes was midwives' experiences of an 'inner conflict' regarding working in smaller teams. CONCLUSION: A strong motivation for working in smaller teams is the wish to provide the best care for pregnant women through offering more continuity of carer. The structure of maternity care, financially and organisationally, acts as a barrier in the transition to working in smaller teams. How community midwives manage these motivators and barriers depends on their personal interests, vision, and personal life. The balance between the motivators and barriers can create an inner conflict among the midwives. This inner conflict encompasses an ethical issue: what is the best care and what is it worth? A discussion within the professional group concerning the practical and ethical aspects of working in smaller teams is needed to find ways to reduce the inner conflict of community midwives who wish to work in smaller teams, thereby promoting the implementation of MLCC.

Bone Regeneration in The Anterior Maxilla with Titanium Mesh and Advanced-Platelet-Rich Fibrin: a Two-Year Follow-up Case Report.

Guided bone regeneration involving the use of titanium mesh and platelet-rich fibrin could be a feasible approach in cases of severely atrophic ridges. The purpose of this case report was to present an esthetic and functional rehabilitation in the anterior maxilla with the installation of dental implants in conjunction with guided bone regeneration using titanium mesh and advanced platelet-rich fibrin (A-PRF). A 60-year-old patient presented bone atrophy and partial edentulism in the anterior maxilla. After clinical and cone beam computed tomography assessment, guided bone regeneration was planned using a titanium mesh and A-PRF with xenograft bone. After eight months of healing, the dental implants were placed with the aid of a surgical guide to obtain accurate three-dimensional positioning. Prosthetic rehabilitation was carried out with individualized crowns. After two years of follow-up, radiographic analysis demonstrated a good quality and density of the bone tissue adjacent to the dental implants. No radiolucent areas were observed, and there were no clinical signs of failure. In cases of severe atrophy, using a titanium mesh and A-PRF proved to be a feasible alternative for bone reconstruction prior to dental implant placement. This approach can aid dental professionals in achieving an ideal implant positioning for rehabilitation with individualized crowns.

Survey of community pharmacists' opinions on drug scheduling in Ontario and Québec.

Background: Over the past decade, Canada has witnessed a shift of several drugs from prescription-only to behind-the-counter (BTC) and over-the-counter (OTC) status. This work examined community pharmacists' agreement with the current scheduling of agents used in the management of allergic rhinitis, heartburn, and vulvovaginitis. Methods: From September to October 2022, an online survey was administered to pharmacists practicing in in Ontario and Québec. The survey aimed to gather insights into their preferred scheduling for 15 medicines commonly used to manage the three selected conditions. Pharmacists were asked whether they agreed with the current scheduling status of each and, if not, how they feel it should be scheduled. Results: 715 pharmacists completed the survey, 462 from Ontario and 253 from Québec. Most were staff pharmacists working 30 or more hours per week, having been a pharmacist for 1-10 years. Ontario pharmacists expressed a preference for scheduling change for five drugs (four prescription [terconazole for intravaginal use, famotidine, rupatadine, mometasone nasal spray] and one unscheduled [ranitidine 75 mg]), while Québec pharmacists expressed preference for scheduling change for three prescription drugs (terconazole for intravaginal use, famotidine, rupatadine). Discussion: As pharmacy practice continues to evolve, pharmacists' comfort with initiating previously prescription-only therapy independently or assisting patients with self-selection may similarly evolve. Of the five drugs identified as having a discrepancy between current status and pharmacist preference, four are prescription and may be candidates to consider for prescription to OTC switch. Conclusion: Pharmacists in Ontario and Québec have expressed preference for most products used in the treatment of allergic rhinitis, heartburn, and vulvovaginitis to be categorised as Schedule II (BTC) or Schedule III (OTC) available only in pharmacies.

Surface treatment of artificial implants with hybrid nanolayers: results of antibacterial tests, leachates and scanning electron microscope analysis.

Purpose: The aim of this study was to evaluate the antibacterial efficacy of surface-treated hernia implants modified by a hybrid nanolayer with incorporated Ag, Cu, and Zn cations using the sol-gel method. Methods: The materials (polypropylene, polyester, and polyvinylidene difluoride) were activated by vacuum plasma treatment or UV C radiation, then modified and tested for bacterial strains of Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive). The AATCC 100 (2019) method for quantitative and the ISO 20645 agar plate propagation method for qualitative evaluation of microbiological efficacy were used. The gradual release of incorporated ions was monitored over time in simulated body fluids (blood plasma, peritoneal fluid) and physiological saline using an inductively coupled plasma mass spectrometer. The thickness and the homogeneity of the layers were measured for individual random samples with scanning electron microscope analysis (SEMA) and evaluated with an elemental analysis. Results: Qualitative and quantitative microbiological tests clearly show the great suitability of vacuum plasma and UV C with sol AD30 (dilution 1:1) surface treatment of the implants. The absolute concentration of Ag, Cu, and Zn cations in leachates was very low. SEMA showed a high degree of homogeneity of the layer and only very rare nanocracks by all tested materials appear after mechanical stress. Conclusion: This study confirms that surface treatment of meshes using the sol-gel method significantly increases the antibacterial properties. The nanolayers are sufficiently mechanically resistant and stable and pose no threat to health.

Finerenone and diabetic renal disease: a narrative review.

Overactivation of mineralocorticoid receptors occurs in cardiorenal diseases. Many patients with type 2 diabetes often progress to chronic kidney disease (CKD) and require dialysis. Finerenone is the first oral non-steroidal mineralocorticoid receptor (MR) antagonist used in patients with diabetic kidney disease and heart failure. Finerenone (also known as Kerendia) is more potent than spironolactone in reducing the progression of CKD and exerts its effect equally on the heart and kidneys, improving cardiovascular outcomes. Research demonstrates that finerenone improves proteinuria and glomerular filtration rate (GFR) if taken alone or in combination with sodium-glucose transporter 2 inhibitors (SGLT2i). Finerenone has been found to decrease mortality in patients with diabetic renal disease and improve quality of life. Its side effects, unlike those of spironolactone, do not include gynecomastia. However, it can result in hyperkalemia, which needs to be monitored. In this narrative review, we aim to investigate the mechanisms of action of finerenone and its implications in patients with type 2 diabetes.

TEAM: Triangular-mEsh Adaptive and Multiscale proton spot generation method.

BACKGROUND: Proton therapy is preferred for its dose conformality to spare normal tissues and organs-at-risk (OAR) via Bragg peaks with negligible exit dose. However, proton dose conformality can be further optimized: (1) the spot placement is based on the structured (e.g., Cartesian) grid, which may not offer conformal shaping to complex tumor targets; (2) the spot sampling pattern is uniform, which may be insufficient at the tumor boundary to provide the sharp dose falloff, and at the same time may be redundant at the tumor interior to provide the uniform dose coverage, for example, due to multiple Coulomb scattering (MCS); and (3) the lateral spot penumbra increases with respect to the depth due to MCS, which blurs the lateral dose falloff. On the other hand, while (1) the deliverable spots are subject to the minimum-monitor-unit (MMU) constraint, and (2) the dose rate is proportional to the MMU threshold, the current spot sampling method is sensitive to the MMU threshold and can fail to provide satisfactory plan quality for a large MMU threshold (i.e., high-dose-rate delivery). PURPOSE: This work will develop a novel Triangular-mEsh-based Adaptive and Multiscale (TEAM) proton spot generation method to address these issues for optimizing proton dose conformality and plan delivery efficiency. METHODS: Compared to the standard clinically-used spot placement method, three key elements of TEAM are as follows: (1) a triangular mesh instead of a structured grid: the triangular mesh is geometrically more conformal to complex target shapes and therefore more efficient and accurate for dose shaping inside and around the target; (2) adaptive sampling instead of uniform sampling: the adaptive sampling consists of relatively dense sampling at the tumor boundary to create the sharp dose falloff, which is more accurate, and coarse sampling at the tumor interior to uniformly cover the target, which is more efficient; and (3) depth-dependent sampling instead of depth-independent sampling: the depth-dependent sampling is used to compensate for MCS, that is, with increasingly dense sampling at the tumor boundary to improve dose shaping accuracy, and increasingly coarse sampling at the tumor interior to improve dose shaping efficiency, as the depth increases. In the TEAM method the spot locations are generated for each energy layer and layer-by-layer in the multiscale fashion; and then the spot weights are derived by solving the IMPT problem of dose-volume planning objectives, MMU constraints, and robustness optimization with respect to range and setup uncertainties. RESULTS: Compared to the standard clinically-used spot placement method UNIFORM, TEAM achieved (1) better plan quality using <60% number of spots of UNIFORM; (2) better robustness to the number of spots; (3) better robustness to a large MMU threshold. Furthermore, TEAM provided better plan quality with fewer spots than other adaptive methods (Cartesian-grid or triangular-mesh). CONCLUSIONS: A novel triangular-mesh-based proton spot placement method called TEAM is proposed, and it is demonstrated to improve plan quality, robustness to the number of spots, and robustness to the MMU threshold, compared to the clinically-used spot placement method and other adaptive methods.

Recruiting Persons With Dementia: A Systematic Review of Facilitators, Barriers, and Strategies.

Study recruitment of persons with dementia is challenging. We aimed to assess facilitators, barriers, and strategies to identify and approach persons with dementia for recruitment to dementia care studies. We systematically searched MEDLINE/PubMed, CINAHL, Web of Science, and other sources (ORRCA [Online Resource for Research in Clinical triAls]; pertinent evidence syntheses; citation searching) and narratively summarised the results (PROSPERO CRD42022342600). Facilitators and barriers consisted of "characteristics of participants, researchers, clinical contact persons", "study characteristics", and "communication with participants". The highest number of participants were recruited by study information in electronic and print formats, as well as by networking and collaboration. Advertisements proved to be the most expensive way of recruitment. There is limited evidence on the impact of recruitment strategies to identify persons with dementia for recruitment to dementia care studies. Our analysis of facilitators and barriers may inform research teams in designing strategies to identify persons with dementia for recruitment purposes.

Breast reconstruction with TiLOOP® Bra: Another arrow in plastic surgeons' quiver?

BACKGROUND: The use of lower-pole sling products has made immediate breast reconstruction a feasible option in women undergoing skin-nipple sparing and skin-reducing mastectomies. To date, available data on the comparative efficacy of biological and synthetic meshes regarding postoperative complications are scattered and limited. METHODS: A systematic literature search was performed to screen three different databases (PubMed, Web of Sciences, and Embase) using the following keywords: "breast reconstruction" AND "TiLOOP®" OR "Titanium-Coated Polypropylene Mesh" OR "TCPM". The perioperative and demographic characteristics of patients, complications profiles, and patient-reported outcomes were considered. RESULTS: We initially identified 234 articles, of which only 41, including 3923 patients and 5042 reconstructed breasts, fully satisfied the inclusion criteria. CONCLUSION: TiLOOP® Bra could be considered a safe and aesthetically valid alternative to Acellular Dermal Matrices (ADMs) in non-smokers patients undergoing skin-nipple sparing and skin-reducing mastectomies and immediate reconstruction. In such populations, complications are more likely to develop in patients with extreme body mass index values. The incidence of seroma with TiLOOP® Bra is comparable to that of ADMs as it is the beneficial effect in radiated patients, where TiLOOP® Bra seems superior to implant alone reconstruction. It has a good bio-integration with host tissues and resistance to infections in patients with a weakened immune system as a consequence of oncologic perioperative treatments.

Rapid diagnosis of coagulopathies from vitamin K deficiency in a consecutive case cohort evaluated by comparative assessment of factor II by one stage assays with prothrombin time versus Ecarin reagents.

BACKGROUND: Vitamin K (VK) deficiency (VKD) impairs γ-carboxylation of VK-dependent coagulation factors (VKDF), resulting in higher factor II (FII) levels measured by Ecarin (FIIE) reagents (that convert des-γ-carboxylated FII to meizothrombin) than by prothrombin time (FII) reagents. OBJECTIVES: To evaluate FII/FIIE abnormalities among patients assessed for coagulopathies and identify findings predictive of coagulopathy improvement after VK. METHODS: We retrospectively assessed consecutive cases between 2002-2021 with FII/FIIE tests and the sensitivity and specificity of FII/FIIE ratios and FIIE-FII differences for VKD defined as INR correction/improvement ≥0.5 after VK. RESULTS: 292 patients (males 58.2%; adults 85.6%; median age 73 years) were evaluated (84.2% hospitalized, 48.3% in intensive care; 71.6% with active liver disease; 28% deceased at discharge) and 25-38% had FII/FIIE findings suggestive of VKD. Among 170 patients assessed for response to VK, FII/FIIE ratios ≤0.84-0.91 and FIIE-FII differences >0.04 U/mL had similar modest sensitivity (47.7-69.3%) and modest to good specificity (67.1-91.5%) for VKD. FII/FIIE ratios <0.86 suggestive of VKD (sensitivity: 47.7%; specificity: 90.2%) were more common in patients deficient in only VKDF (p=0.0001), but were detected in 16% with non-VKDF deficiencies. Low FIIE was commonly associated with active liver disease (p=0.0002). Patients with and without probable VKD (based on FII/FIIE ratios <0.86), had similar mortality, bleeding and rates of prothrombin complex concentrate and red cell transfusions (p≥0.78), but fewer with probable VKD received plasma and fibrinogen replacement (p≤0.024). CONCLUSION: FII/FIIE comparison aids the diagnosis of VKD and predicts clinical responses to VK treatment among patients with coagulopathies.

Longitudinal Changes in Maximal Forced Inspiratory Flow and Clinical Outcomes in COPD Patients.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) primarily impairs expiratory flow due to progressive airflow obstruction and reduced lung elasticity. Increasing evidence underlines the importance of inspiratory flow as a biomarker for selecting inhaler devices and providing ancillary aerodynamic information. RESEARCH QUESTION: Does the longitudinal changes in maximum forced inspiratory flow (FIFmax) influence acute exacerbations and lung function decline in COPD patients? STUDY DESIGN AND METHODS: This longitudinal study observed FIFmax in COPD patients over a 7-year period from 2004 to 2020. Eligible patients were categorized into two groups based on FIFmax trajectory: the increased FIFmax group and the decreased FIFmax group. Our study assessed the annual rate of acute exacerbations and the annual decline rate of forced expiratory volume in 1 second (FEV1). Subgroup analyses were conducted based on treatment status, with a focus on inhaled therapy and inhaler device usage. RESULTS: Among the eligible 956 COPD patients, 56.5% belonged to the increased FIFmax group. After propensity score matching, the increased FIFmax group experienced lower rates of severe exacerbations (0.16/yr vs. 0.25/yr, P-value=0.017) and a slower decline in FEV1 (0 [interquartile range (IQR), -51-71] vs. -43 [IQR, -119-6] ml/yr, P-value<0.001) compared to the decreased FIFmax group. These associations were particularly prominent in patients using specific inhaler therapies, such as DPI therapies. INTERPRETATION: Our study revealed that the longitudinal changes in FIFmax are associated with clinical outcomes in COPD patients. Patients with increased FIFmax experienced a lower rate of severe exacerbations and a slower decline in lung function. These findings suggest the potential benefits of optimizing inspiratory flow in COPD management, though further studies are needed to confirm these observations due to potential confounding factors.

The Use of Biologic Mesh for Repair of Perianal Fistulas.

This is a case series of three patients who presented with complex anorectal fistulas. Each patient underwent repair of complex anorectal fistulas with biologic mesh. We will discuss each case and our institution's experience with this relatively new technique. This case series demonstrates the use of biologic mesh for the repair of complex anorectal fistulas. Three patients are discussed who underwent repair of perianal fistulas using ACell mesh by two separate surgeons. We will discuss the rationale for offering this treatment, as well as the advantages and disadvantages. The use of biologic mesh in perianal fistulas is a relatively new topic that needs further investigation. Perianal fistulas can be difficult to manage for both patients and surgeons. There are many options for repair, ranging from simple to complex. Biologic mesh for complex fistulas may be a useful option to avoid the morbidity of more complex repairs, such as flaps.

Emergency department utilization among adults with epilepsy: A multi-state cross-sectional analysis, 2010-2019.

OBJECTIVE: We described patterns and trends in ED use among adults with epilepsy in the United States. METHODS: Utilizing inpatient and ED discharge data from seven states, we conducted a cross-sectional analysis to identify adult ED visits diagnosed with epilepsy or seizures from 2010 to 2019. Using ED visit counts and estimates of state-level epilepsy prevalence, we calculated ED visit rates overall and by payer, condition, and year. RESULTS: Our data captured 304,935 ED visits with epilepsy as a primary or secondary diagnosis in 2019. Across the seven states, visit rates ranged between 366 and 726 per 1000 and were higher than rates for adults without epilepsy in all states but one. ED visit rates were highest among Medicare and Medicaid beneficiaries (vs commercial or self-pay). Adults with epilepsy were more likely to be admitted as inpatients. Visits for nervous system disorders were 6.3-8.2 times higher among people with epilepsy, and visits for mental health conditions were 1.2-2.6 times higher. Increases in ED visit rates from 2010 to 2019 among people with epilepsy exceeded increases among adults without by 6.0-27.3 percentage points. CONCLUSION: Adults with epilepsy visit the ED frequently and visit rates have been increasing over time. These results underscore the importance of identifying factors contributing to ED use and designing tailored interventions to improve ambulatory care quality.

Prevalence and factors associated with unhealthy metabolic status according to body mass index: analysis of a national nutritional survey.

INTRODUCTION: Although obesity substantially influences public health owing to related comorbidities, it has been discovered that the incidence of such issues is not directly related to obesity but to the patient's unhealthy metabolic status (MUS) independent of the body mass index (BMI). OBJECTIVES: To describe the prevalence of UMS overall and according to BMI and determine the factors associated with it. METHODS: A cross-sectional analytical study was used based on the analysis of secondary databases called the Life Stage Nutritional Surveillance Survey (VIANEV). Participants were selected in two stages, finally obtaining 885 participants. UMS was defined based on the criteria of the Adult Treatment Panel III used to define metabolic status in a set of 5 parameters, if the subject presented two or more alterations it was considered UMS. Six groups were formed according to BMI: metabolically healthy, average weight (MHNW) and unhealthy (MUNW), metabolically healthy, overweight (MHOW) and unhealthy (MUOW), metabolically healthy, obese (MHO) and unhealthy (MUO).). RESULTS: The total prevalence of UMS was 73.11%, with MUNW, MUOW, and MUO being 47.90%, 80.34%, and 96.44%, respectively. Only 5.31% did not present any metabolic alteration. The multivariable analysis found variations globally according to sex, age, marital status, geographical region, smoking habit, and altitude. CONCLUSIONS: A high prevalence of UMS was observed in Peru, indicating that BMI alone is not a sufficient indicator of metabolic status. These findings suggest that strategies should be prioritized to address the growing problem of UMS, considering the particularities of each subpopulation and using a multifaceted approach that addresses modifiable and non-modifiable risk factors.

Surgical reconstruction of a composite nasomaxillary and superior labial defect in a dog with a fascia lata graft, titanium mesh implant and angularis oris axial pattern flap.

Objective: To document the successful surgical reconstruction of a composite nasomaxillary and superior labial defect using a fascia lata graft, titanium mesh and angularis oris axial pattern flap in a dog. Case summary: An estimated 2-year-old female intact mixed-breed dog was presented with a composite (hard and soft tissue) nasomaxillary defect, suspected to be caused by a chemical burn. Physical examination revealed nasal discharge, exposed bilateral maxilla and nasal bone, nasomaxillary fistula with air movement, and intrinsic discoloration of the left maxillary canine tooth. The soft tissue lesion extended from the nasal planum rostrally to the medial canthus of the left eye distally and from the right maxillary bone to include a full thickness loss of the left maxillary labium laterally. Computed tomographic images of the head showed chronic osteomyelitis of the maxilla, zygomatic and nasal bones with nasomaxillary fistula and numerous exposed roots of the left maxillary premolars. Staged surgical procedures to address the dentition and nasomaxillary defect were planned. The first procedure consisted of the extraction of periodontally compromised left maxillary premolars, and standard root canal therapy of bilateral maxillary canine teeth. The second procedure consisted of debridement of the non-vital soft and hard tissues and surgical reconstruction of the nasomaxillary defect after virtual surgical planning. Head computed tomography performed 5 months post-operatively revealed a decrease in the size of the osseous defect as well as the resolution of rhinitis. Clinical relevance: This case demonstrates the feasibility of using a combination of soft tissue graft, titanium mesh, and axial pattern flap in managing nasomaxillary defects. Such defects can lead to chronic rhinitis, infection, discomfort, and long-term morbidity. This case report provides a novel but practical approach for managing defects in the nasomaxillary region in dogs.

Idiopathic cardiac ossification with Chiari mesh in the right atrium: a case report and literature review.

Background: Idiopathic cardiac osseous metaplasia in the right atrium of a 9-year-old boy, accompanied by right atrial Chiari network and right pulmonary artery embolism. This case is rare and can easily be misdiagnosed. Case Description: We encountered a case of a 9-year-old boy with a 3.5 cm diameter neoplasm in the right atrium. Preoperative imaging diagnosis could not determine the nature of the tumor, and the initial clinical suspicion of cardiac myxoma. After admission, a cardiotomy to remove foreign bodies and a pulmonary artery thrombectomy were performed. Conclusions: Idiopathic cardiac osseous metaplasia is relatively rare, and it is even rarer to be accompanied by a Chiari network in the right atrium. Due to the location and characteristics of the lesion in this case, it is easy to be misdiagnosed as atrial myxoma in clinical practice. Whether it is idiopathic osseous metaplasia or myxoma, it needs to be performed surgical treatment and pathological examination can easily rule out the diagnosis of myxoma. However, as idiopathic cardiac metaplasia is difficult to encounter in clinical work and there are few reports in the literature, clinicians and pathologists need to consult more relevant literature. Learn to understand and master the disease through multi-party consultation.
