Peripherally induced movement disorders in the stomatognathic system after oral surgical or dental procedures.

Peripherally induced movement disorders (PIMD) are hyperkinetic movement disorders that can occur after injury to a part of the body. This study aimed to identify PIMD in the stomatognathic system following dental or oral surgical procedures. A total of 229 patients with PIMD (144 women and 85 men; mean age: 53.4 years) triggered by oral surgical or dental interventions were evaluated retrospectively. The average latency between the procedures and onset of PIMD was 14.3 days. Oral surgery (40.2%), including tooth extraction, trauma treatment, and other surgical procedures, was the most frequent trigger of PIMD. This was followed by general dental treatment, including periodontal, endodontic, and restorative procedures (36.7%), prosthetic treatment (19.7%), and orthodontic treatment (3.5%). PIMD consisted of oromandibular dystonia (73.8%), functional (psychogenic) movement disorders (11.4%), orolingual dyskinesia (7.9%), and hemimasticatory spasms (5.7%). These results suggest that even minor alterations in normal anatomy or physiology after dental procedures may result in PIMD in predisposing patients. Dental professionals should be aware that although infrequently, PIMD can develop after various dental treatments. If such symptoms precipitate, the attending physician should properly explain them to the patient and provide appropriate treatment or consultation with a movement disorder specialist.

Disability and Patient-Reported Satisfaction in Women with Idiopathic Intracranial Hypertension: A Comparative Study of Venous Sinus Stenting and Medical Management

Objective: Patients with chronic idiopathic intracranial hypertension (IIH) commonly experience a high level of disability and low satisfaction with medical treatment. We aim to evaluate long-term functional improvement and patient satisfaction in IIH patients with similar symptoms by comparing venous sinus stenting (VSS) to standard medical therapy. Methods: We conducted a cross-sectional questionnaire study of 111 IIH patients, comparing 37 adult female patients who underwent venous sinus stenting with 74 patients treated medically. Propensity score matching was used to balance age and presence of papilledema at presentation between groups. Headache-related disability was evaluated using the Migraine Disability Assessment Scale (MIDAS), while general function and treatment satisfaction were assessed using custom questionnaires. Electronic medical records and the results of imaging upon diagnosis were reviewed retrospectively. Results: The stented group reported significantly better outcomes in physical well-being (median 4.0 vs. 1.0, p < 0.001), task completion (4.0 vs. 1.0, p < 0.001), work/school persistence (5.0 vs. 1.0, p < 0.001), and mental well-being (4.0 vs. 1.0, p < 0.001). Additionally, the stented group had a lower proportion of patients with severe MIDAS (MIDAS > 4, 24.3% vs. 47.9%, p = 0.017). Logistic regression suggested venous stenting as a protective factor against severe MIDAS scores (OR = 0.174, p = 0.004). Conclusion: Cerebral venous stenting in patients with IIH is associated with lower disability and higher patient satisfaction from medical treatment compared to those treated with medications only. These findings suggest that venous sinus stenting may be a valuable treatment option for selected IIH patients. However, larger prospective studies are needed to further validate our results.

Response of a relativistically streaming pulsar plasma

The response tensor is derived for a relativistically streaming, strongly magnetized, one-dimensional Jüttner distribution of electrons and positrons, referred to as a pulsar plasma. This is used to produce a general treatment of wave dispersion in a pulsar plasma. Specifically, relativistic streaming, the spread in Lorentz factors in a pulsar rest frame and cyclotron resonances are taken into account. Approximations to the response tensor are derived by making approximations to relativistic plasma dispersion functions appearing in the general form of the response tensor. The cold-plasma limit, the highly relativistic limit and limits related to cyclotron resonances are considered. The theory developed in this paper has applications to generalized Faraday rotation in pulsars and magnetars.

Oral function status of older patients seeking dental implant treatment.

In recent years, dental implant treatment has become an option for prosthetic treatment for missing teeth and is often performed in older patients. However, the complex oral functional decline in old age presents challenges in terms of frailty prevention, making oral function management after prosthetic treatment crucial. Nonetheless, the actual status of oral function in older patients seeking dental implant treatment remains unclear. In this study, we aimed to assess the oral function status of older patients seeking dental implant treatment. Among patients receiving prosthetic treatment for missing teeth, 227 older patients (111 in the pre-dental implant group and 116 in the pre-bridge/denture group) who underwent a thorough examination of their oral function were included in this study. Age, sex, comorbidities, smoking status, number of functional teeth, and occlusal support status were obtained from the medical records. Statistical analyses were performed using the t-test, chi-square test, and logistic regression (p < 0.05). Compared with the pre-bridge/denture group, the pre-dental implant group had significantly better oral hygiene, occlusal force, tongue-lip motor function, tongue pressure, masticatory function, and swallowing function and a significantly lower prevalence of oral hypofunction. Older age and decreased occlusal support were associated with the diagnosis of oral hypofunction, even after adjusting for confounding factors including prosthetic treatment. Although older patients seeking dental implant treatment have a higher oral function than those seeking general prosthetic treatment, older age and a lower number of occlusal supports suggest that appropriate oral function management is needed.

Accuracy of 3-dimensional surgical guide for endodontic microsurgery with a new design concept: A cadaver study.

Despite the high success rate of endodontic microsurgery (EMS), it is difficult to suggest EMS as a general treatment option considering the difficulty of the procedure. A surgical guide has been proposed to overcome this problem. This study aimed to evaluate the stability of the surgical guide of a new design concept, as well as the accuracy of root resection, and to introduce the manufacturing method of the newly designed surgical guide. The experiment was conducted on 59 roots (9 in the maxillary and 50 in the mandibular region) of adult human cadavers. The surgical guide was designed using CAD/CAM design software based on cone-beam computed tomography (CBCT) images and optical scan files. Unlike conventional surgical guides, the surgical guide proposed herein was designed to act as a tooth-bone-supported removable appliance. Two different types of guides were prepared: the osteotomy guide (O guide) for separation of the cortical bone above the root tip with a trephine bur with an outer diameter of 6 mm and the root resection guide (R guide) for resection of the root tip with a trephine bur with an outer diameter of 4 mm. For stability evaluation, the guides were pressed at five predetermined locations after installation and checked for the presence of any movement. For accuracy evaluation, the length at which the root tip was cut was measured and examined by overlapping the preoperative and postoperative CBCT images. Of the 15 R guides, 14 were stably installed without mobility. For the R guide group, the root tip was resected with an average of 3.2 mm, showing better results than the no-guide group with an average of 4.0 mm. The newly designed surgical guide of this study can be applied more stably, enabling root resection to be performed more accurately and simply according to the preoperative plan than when performed without a guide.

A critical review on usage of Ghrita in Pandu

According to Ayurveda, human body is made up from Saptdhatu, Tridosha and Trimal. These are the main functional unit which maintains equilibrium in body. Agni plays most important role in metabolism of body. With the help of Agni, food is converted into absorbable form and also it forms and nourishes Saptdhatu in progressive manner continuously. Any type of disequilibrium in the process, gives rise to diseases like Pandu, Grahani, Kushtha etc. Pandu Roga is disease entity described in Ayurvedic literature which is characterized as pallor complexion of the skin of the diseased person. Pandu is widely described in various Ayurvedic texts as an independent disease and also as associated symptom in many other diseases. The general treatment of Pandu is Snehana, Shodhana, Shamana with herbo-mineral combinations along with dietary modifications. There is specific mention of internal oleation before Shodhana Chikitsa is advised which marks its importance in treatment. Ghritpan is considered best for ignition of Jatharagni as well as Dhatvagni and it also has properties like Jivaniya, Rasayana etc. Ghritapan opposes the etiology of Pandu at level of constitution and diet. In Pandu Chikitsa Adhyay, various medicated Ghrita are described. This present study critically reviews role of Ghritapan in Pandu and different combination of medicated Ghrita described in Pandu Chikitsa Adhyay by Acharya Charaka along with its specific indications.

Multidisciplinary approach and host optimization for fracture-related infection management

In orthopaedic trauma, fracture-related infections (FRI) are still dreadful challenges that can cause non-union, amputation and even death. Standardization of general treatment strategies for FRI is still lacking. Due to the complexity of FRI, a multidisciplinary approach addressing host status, state of the fracture and causative microorganism has been applied in the management of FRI. Surgical treatment, antibiotic therapy and host optimization for FRI were summarized and discussed. The goal of this review is to provide an overview and summary of current approaches of FRI management and to make suggestions on FRI prevention and treatment based on multidisciplinary principles.

An exploration of the postural, location- and social contact- related sub-characteristics of inactive but awake behaviour as a depression-like indicator in mice

Inactive behaviour is essential to life. However, specific forms of inactivity may be indicative of compromised welfare in certain captive conditions. Inactive but awake behaviour (IBA - spontaneous, motionless awake behaviour without interacting with the surroundings) has been documented in some species and may be associated with poor welfare and negatively valenced affective states. In our previous work in laboratory mice, we have identified environmental risk factors (non-enriched housing) and curative factors (antidepressant drug Venlafaxine) for IBA and we hypothesise that greater levels of IBA may represent a depression-like state in this species. Here we aimed to identify which specific sub-characteristics of IBA would show construct validity as a depression-like state by exploring the posture (i.e. lying, curled lying or sitting), social contact position (i.e. in physical contact with a cage mate or not) and location of mice while performing the behaviour during two experiments (respectively investigating the aetiology and the curative factors of IBA). In both experiments we expected that more IBA would be displayed in standard (non-enriched) laboratory cages, compared with large highly-enriched cages and that a move from a highly-enriched to a non-enriched cage would increase IBA, while the opposite treatment would result in a decrease. In our second experiment (curative factors investigation), we predicted that less IBA would be displayed by mice that voluntarily ingested an antidepressant (Venlafaxine) versus a placebo. Because we could not control the number of instances of each IBA sub-characteristic we measured and we had no a priori predictions about which IBA sub-characteristics would match our general IBA treatment predictions, we compared the effect size and the direction of the effect between our treatment groups to explore which of the sub-characteristics matched our general IBA predictions. Overall, we found little variation in the location IBA was performed, with the majority being seen in the nest. Across treatment comparisons in both experiments, overall, the largest effect sizes were measured for IBA performed when in contact with the cage mate and performed when lying and both characteristics generally matched the direction of our treatment-related predictions. We suggest that future work should perform more detailed analyses of the specific characteristics of IBA by identifying behavioural sequences and the co-occurrence of the sub-characteristics to obtain a more complete picture of IBA as a depression-like indicator.

Immune Checkpoint Inhibitors in the Emergency Department

Immune-checkpoint inhibitors (ICIs) have transformed the landscape for cancer treatment by enhancing the endogenous immune system’s ability to eliminate cancer cells. Tumor cells evade the body’s immune response by blocking T cell activation; ICIs function by blocking this inhibition, thereby boosting the immune system’s ability to kill tumor cells. Despite producing astonishing improvements in prognosis and remission-free time frames for cancer patients, ICIs carry risks for well documented treatment-related complications and immune-related adverse events (irAEs) that can be life-threatening. IrAEs can occur in almost any organ system, and they usually occur early in treatment, typically within the first three months. Some common complications involve the cutaneous, gastrointestinal tract, pulmonary, and endocrine organ systems. Guidelines outlining the general treatment algorithms for irAEs have been published by the Society for Immunotherapy of Cancer (SITC) and the National Comprehensive Cancer Network (NCCN). When patients present to the Emergency Department with symptoms consistent with irAEs, a rigorous and thorough infectious work-up is required, and treatment usually begins. This includes immunosuppression with corticosteroids, symptomatic treatment, and/or discontinuation of the ICI depending on the grade and severity of presentation. Early recognition and management of irAEs among ED providers, in conjunction with treating oncologists, are imperative to improve patient outcomes in the Emergency Department.

Clinical features and prognostic factors of AIDS-associated diffuse large B-cell lymphoma

To explore the general clinical features and treatment outcomes of patients with AIDS-related diffuse large B-cell lymphoma (AIDS-DLBCL) and provide a theoretical basis for diagnosis and treatment, survival prognosis, prevention and management of AIDS-DLBCL patients. AIDS-DLBCL patients who received combined antiretroviral therapy (cART) at Changsha First Hospital from January 2017 to January 2020 were selected in this study. The survival curves were plotted using the Kaplan-Meier method, and the Cox proportional hazards regression model was used to analyze the association between AIDS-DLBCL specific variables and progression-free survival and overall survival. Correlation analysis was conducted based on the clinical features of the patients. A total of 50 AIDS-DLBCL patients were included. Their median age (Q1, Q3) was 52 (44, 59) years, of whom 46 (92%) were male. About 20 (40%) patients received treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), while 23 patients (46%) received treatment with rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP). Survival curve analysis showed that the 2-year progression-free survival rate and overall survival rate of AIDS-DLBCL patients were 56.9% and 61.6%, respectively. Patients with RCHOP protocol combined with EBV-DNA≥1 000 copies/ml had higher progression-free survival rate (χ2=3.844, P=0.043) and overall survival rate (χ2=4.662, P=0.031) than those with CHOP protocol combined with EBV-DNA≥1 000 copies/ml. A multivariate analysis showed that male (HR=2.70, 95%CI:1.10-6.80), EB viral load≥1 000 copies/ml (HR=1.75, 95%CI:1.12-2.84), HIV-RNA≥200 copies/ml (HR=4.64, 95%CI: 1.73-12.15), ECOG PS score of 2 to 4 points (HR=3.54, 95%CI:1.62-7.33), and international prognostic index (IPI) score of 3 to 5 points (HR=5.21, 95%CI:1.39-20.14) were at a higher risk of disease progression. Patients with EB viral load≥1 000 copies/ml (HR=0.07, 95%CI:0.05-0.93) on the RCHOP regimen had a small risk of disease progression. Males (HR=2.87, 95%CI:1.65-9.17), EB viral load≥1 000 copies/ml (HR=1.61, 95%CI:4.02-9.36), HIV-RNA≥200 copies/ml (HR=1.19, 95%CI:1.58-2.74), ECOG PS score of 2 to 4 (HR=6.42, 95%CI:2.55-14.33), IPI score of 3 to 5 points (HR=2.78, 95%CI:1.41-12.96) had a high risk of mortality. Patients with EB viral load≥1 000 copies/ml (HR=0.24, 95%CI:0.64-0.90) on the RCHOP regimen had a low risk of mortality. In summary, males, ECOG physical status score of 2 to 4 points, IPI score of 3 to 5 points, EB viral load≥1 000 copies/ml and HIV viral load≥200 copies/ml are risk factors affecting progression-free survival and overall survival of AIDS-DLBCL patients. RCHOP regimen combined with EB viral load≥1 000 copies/ml is a protective factor affecting progression-free survival and overall survival in AIDS-DLBCL patients.

Human Stem Cell Therapy for the Cure of Type 1 Diabetes Mellitus (T1D): A Hurdle Course between Lights and Shadows

Background: T1D is a severe metabolic disorder due to selective autoimmune pancreatic islet β-cell killing, which results in complete abrogation of endogenous insulin secretion. The affected patients, once the disease is clinically overt, must immediately undertake insulin supplementation according to intensive therapy regimens to prevent the onset of acute and chronic complications, some of them potentially lethal. Replacement of the destroyed β-cells with fresh and vital pancreatic endocrine tissue, either of the whole organ or isolated islets transplantation, started a few decades ago with progressively encouraging results, although exogenous insulin withdrawal was obtained in a minor cohort of the treated patients. The restricted availability of donor organs coupled with general immunosuppression treatment of recipients to avoid graft immune rejection may, at least partially, explain the limited success achieved by these procedures. Results: The introduction of pluripotent stem cells (either of human embryonic origin or adult cells genetically induced to pluripotency) that can be differentiated toward insulin secretory β-like cells could provide an indefinite resource for insulin-producing cells (IPCs). Conclusions: Because the use of human embryos may encounter ethical problems, employment of adult multipotent mesenchymal stem cells (MSCs) extracted from several tissues may represent an alternative option. MSCs are associated with strong immunoregulatory properties that can alter early stages of β-cell-directed autoimmunity in T1D, other than holding the potential to differentiate themselves into β-like cells. Lights and shadows of these new strategies for the potential cure of T1D and their advancement state are reviewed.

The clinical outcomes and prognostic factors of dedifferentiated central chondrosarcoma in extremities

ObjectiveThis study was to analyze the clinical outcomes and prognostic factors of dedifferentiated central chondrosarcomas (DCCS) in extremities.MethodsA retrospective study was conducted on 49 patients (27 males, 22 females) who underwent surgical treatment between January 2001 and March 2023 in our institution. All patients were diagnosed with dedifferentiated central chondrosarcomas by needle biopsy or postoperative histopathological examination. The general characters, treatment and clinical outcomes were recorded in the follow-up and all surgical-related complications that occurred were recorded in this study. Overall, these data were used to analyse the prognostic factors of DCCS.Results49 patients were included in this retrospective study and there were no patients lost in the follow-up period. The median diagnosis age of all patients was 57 years old (ranging from 17 to 87) and the median follow-up time was 34 months (range, 1-289). The average tumor size was 9.6 ± 2.4 cm (3.0-15.5). Median overall survival (OS) and progression-free survival (PFS) were 34 and 23 months, respectively. The 1-year, 2-year, 5-year, and 10-year OS were 87.8% (95% CI 77.6%-98.0%), 71.4% (35/49), 28.6% (14/49) and 18.4% (9/49). And the 1-year, 2-year, 5-year, and 10-year PFS were 75.5% (95% CI 63.6%-87.4%), 49.0% (35/49), 26.5% (14/49) and 16.3% (9/49). Multiple variate analyses indicated metastasis, pathological fracture, Enneking staging and surgical margin were independent prognostic factors in extremity dedifferentiated central chondrosarcomas.ConclusionsDedifferentiated central chondrosarcomas in extremities still had a grave prognosis. Metastasis, pathological fracture, Enneking staging, and surgical margin were independent risk factors for prognosis.Evidence levelIV Therapic.

The current diagnosis and treatment situation of rare disease in the pediatric intensive care unit

Objective: To analyze the diagnosis and treatment of children with rare diseases in the pediatric intensive care unit (PICU), the distribution of disease types and populations, clinical characteristics, and the use of orphan drugs. Methods: A retrospective case summary was conducted. Data were collected from 105 children aged 29 days to <18 years with a confirmed diagnosis of rare diseases according to the "First Batch of Rare Disease Catalogue in China" who were admitted to the PICU of Beijing Children's Hospital, Capital Medical University from January 2020 to December 2022. Data including general information, auxiliary examinations, and treatment details for each patient were collected from the hospital's electronic medical record system. Patients were divided into age groups: infancy (29 days to<1 year), early childhood (1 to <3 years), preschool age (3 to<7 years), school age (7 to<13 years), and adolescence (13 to<18 years). The chi-square test was used to compare gender distribution differences among various rare diseases. Results: A total of 105 patients with 130 cases meeting the diagnostic criteria were included, accounting for 4.7% (130/2 754) of the total admissions to the PICU. The age at PICU admission was 5.3 (0.8, 9.5) years and there were 81 cases in male. The 3 most common types of diseases were endocrine, nutritional, and metabolic diseases (37 cases); followed by neurological disorders(32 cases); and congenital malformations, deformities, and chromosomal abnormalities(17 cases). The 5 most common rare diseases were methylmalonic acidemia (14 cases), mitochondrial encephalomyopathy (14 cases), atypical hemolytic uremic syndrome (12 cases), autoimmune encephalitis (12 cases), and idiopathic cardiomyopathy (9 cases). The distributions of common rare diseases varied among different age groups. In infants, atypical hemolytic uremic syndrome was most common (6 children). There was no statistically significant difference regarding gender among children with mitochondrial encephalomyopathy (13.6% (11/81) vs. 6.1% (3/49), χ2=1.77, P=0.184). Respiratory failure (36 cases) was the primary reason for rare diseases children to be admitted to the PICU. A total of 95 cases underwent mechanical ventilation, 39 cases received multidisciplinary collaborative diagnosis and treatment, and only 6 children received orphan drug therapy during their stay in the PICU. Conclusions: Rare diseases are not uncommon in PICU. Endocrine, nutritional and metabolic disorders, neurological disorders, congenital malformations, deformities, and chromosomal abnormalities were common. Methylmalonic acidemia, mitochondrial encephalomyopathy, atypical hemolytic uremic syndrome and autoimmune encephalitis have higher cases. Many children with rare diseases in the PICU have complex conditions those are challenging to treat, requiring multidisciplinary collaboration. The utilization rate of orphan drugs among children with rare diseases in PICU needs to be improved.

Comparative Study of Waste Management and Sampling Practices in Latvia and Estonia

Abstract The study focuses on waste management and sampling practices carried out in two large Baltic cities: Riga (Latvia) and Tartu (Estonia). Even though waste collection schemes are not at the same centralisation level in the two municipalities, certain similarities can be observed in waste collection, management and sampling processes. Governed by provisions of Council Directive 1999/31/EC of 26 April 1999 on the landfill of waste, general national waste treatment legislation, and the national waste management plans, waste management practices in Latvia and Estonia are moving towards minimalisation of waste landfilling and maximalisation of waste inclusion into various recycling practices (use in waste biodegradation cells, bioreactors, different waste recycling facilities, in developing modern waste management supporting infrastructure, etc.). Therefore, waste management in two countries can be partly characterised as a vital element of emerging circular economy activities aimed at minimising landfill deposition of waste, hence, a more effective and permanent approach to sustainable waste management problems, on the one hand, and maximising the diversified use of waste in different branches of economy, hence, larger economic and social benefits.

Ten tips to manage oral anticoagulation in hemodialysis patients with atrial fibrillation

ABSTRACT Patients with chronic kidney disease (CKD) have a high incidence and prevalence of atrial fibrillation (AF). While general treatment strategies for AF may largely be transferred to patients with mild to moderate CKD, patients with advanced CKD—particularly hemodialysis (HD) patients—with AF pose substantial therapeutical challenges to cardiologists and nephrologists. The arguably greatest dilemma is the very limited evidence on appropriate strategies for prevention of stroke and systemic embolism in HD patients with AF, since the risk for both thromboembolic events without oral anticoagulation and severe bleeding events with oral anticoagulation are substantially increased in advanced CKD, compared with the general population. Thus, the benefit to risk ratio of either vitamin K antagonists or direct oral anticoagulants is less evident in HD than in non-CKD patients with AF. As a multidisciplinary panel of clinicians, we here propose 10 tips that may help our colleagues to navigate between the risk of undertreatment—exposing CKD patients with AF to a high stroke risk—and overtreatment—exposing the very same patients to a prohibitively high bleeding risk. These tips include ideas on alternative risk stratification strategies and novel treatment approaches that are currently in clinical studies—such as factor XI inhibitors or left atrial appendage closure—and may become game-changers for HD patients with AF.

Diagnosis of 42 Cases of Intrauterine Twin Pregnancy Complicated With Ectopic Pregnancy: A Retrospective Cohort Study.

The coexistence of intrauterine twin pregnancy and ectopic pregnancy (EP), known as heterotopic pregnancy, is a rare but potentially life-threatening condition. In this study, we aimed to investigate the pregnancy outcomes in women with intrauterine twin pregnancies complicated with EP after assisted reproductive technology. This retrospective study analyzed the medical records of 42 women diagnosed with intrauterine twin pregnancies complicated with EP via ultrasound or surgery at our hospital between January 2005 and December 2020. We collected data on patient general characteristics, high-risk factors, clinical symptoms, ultrasound features, treatment methods, and pregnancy outcomes. Among the 42 included women, 47.6% (20/42) had a history of tubal surgery, while 52.4% (22/42) and 47.6% (20/42) received the transfer of 2 and 3 embryos, respectively. In terms of treatment, 21.4% (9/42) women received expectant management, whereas 78.6% (33/42) underwent surgical treatment, with laparoscopic surgery accounting for 71.4% (30/42). Tracking the pregnancy outcomes revealed a live birth rate of 81.0% (34/42) and a full-term birth rate of 50.0% (21/42). The preterm birth rate was 31.0% (13/42), with a breakdown of 1 singleton (7.7%, 1/13) and 12 twin births (92.3%, 12/13) among the total 13 premature deliveries. Among the neonates, 33.3% (14/42) were singletons and 47.6% (20/42) twins. Caesarean section accounted for 31 out of 34 deliveries (91.2%). Though the incidence of EP in twin pregnancies has declined in the last decade, early diagnosis and proper management are still crucial for favorable outcomes in twin pregnancies with EP.

Commercial Silver-Based Dressings: In Vitro and Clinical Studies in Treatment of Chronic and Burn Wounds.

Chronic wounds are a major health problem because of delayed healing, causing hardships for the patient. The infection present in these wounds plays a role in delayed wound healing. Silver wound dressings have been used for decades, beginning in the 1960s with silver sulfadiazine for infection prevention for burn wounds. Since that time, there has been a large number of commercial silver dressings that have obtained FDA clearance. In this review, we examine the literature involving in vitro and in vivo (both animal and human clinical) studies with commercial silver dressings and attempt to glean the important characteristics of these dressings in treating infected wounds. The primary presentation of the literature is in the form of detailed tables. The narrative part of the review focuses on the different types of silver dressings, including the supporting matrix, the release characteristics of the silver into the surroundings, and their toxicity. Though there are many clinical studies of chronic and burn wounds using silver dressings that we discuss, it is difficult to compare the performances of the dressings directly because of the differences in the study protocols. We conclude that silver dressings can assist in wound healing, although it is difficult to provide general treatment guidelines. From a wound dressing point of view, future studies will need to focus on new delivery systems for silver, as well as the type of matrix in which the silver is deposited. Clearly, adding other actives to enhance the antimicrobial activity, including the disruption of mature biofilms is of interest. From a clinical point of view, the focus needs to be on the wound healing characteristics, and thus randomized control trials will provide more confidence in the results. The application of different wound dressings for specific wounds needs to be clarified, along with the application protocols. It is most likely that no single silver-based dressing can be used for all wounds.

What should we be studying? Research priorities according to women and gender-diverse individuals with sexual interest/arousal disorder and their partners.

Sexual interest/arousal disorder (SIAD) is one of the most common sexual problems for women. In clinical research, there are often misalignments between the research priorities of patients and researchers, which can negatively impact care, and gender-diverse individuals are often excluded from research. Inclusion of patient perspectives when establishing research priorities may help to reduce these gaps; however, the research priorities of couples coping with SIAD remain unclear. Identify the research priorities of women and gender-diverse individuals with SIAD and their partners. In an online survey, couples coping with SIAD provided consent and responded to an open-ended question asking them to list the top 3 things they think are important for researchers to focus on related to couples coping with low sexual desire. A team-based content analysis was conducted to identify themes and their frequency of endorsement. An author-developed open-ended question. Analysis of 1279 responses (n = 667 from women and gender-diverse individuals with SIAD, n =612 from partners) resulted in our identification of 6 main themes: general causes, general treatment and coping, biophysiological, relationship, psychological, and environmental/contextual. Additionally, we identified 4 sub-themes within each of the latter 4 main themes: general, cause, treatment, and impact. For women and gender-diverse individuals with SIAD, their partners, and specifically gender-diverse participants, the 3 most endorsed themes were psychological general factors (24.3%, 21.2%, 24.3%; eg, stress and the link between SIAD and anxiety), relationship general factors (15.7%, 13.2%, 18.6%; eg, relationship length and communication on sexual desire), and biophysiological general factors (12.3%, 12.4%, 14.3%; eg, research on medications and hormones). Clinical researchers should consider the research priorities of couples coping with SIAD to ensure their work aligns with the needs of the affected population. This study is the first to identify the research priorities of both women and gender-diverse individuals with SIAD and their partners. Most participants identified as heterosexual, North American, and of middle to high socioeconomic status; results may not generalize. Responses were sometimes brief and/or vague; interpretation of these responses was therefore limited and may have required more contextual information. Findings suggest that women and gender-diverse individuals with SIAD, their partners, and gender-diverse participants have similar research priorities that are consistent with a biopsychosocial approach to research. Heterogeneity of responses across themes supports a multidisciplinary, patient-oriented approach to SIAD research.

General dentists’ treatment plans in response to cosmetic complains; a field study using unannounced-standardized-patient

BackgroundThis field study explored general dentists' treatment plans in response to the request for cosmetic services of an unannounced standardized patient (USP) in Mashhad, Iran. MethodsThe researcher, as a USP, visited 24 and 23 offices in a high-income and a low-income area, respectively. The primary complaint was that, according to her friend's comments, a dental student, her smile was "crooked and yellow" due to the congenitally missing tooth number 10 and peg-shaped tooth number 8. The dentists' treatment plans for teeth color and form and the cosmetic services expenses were recorded. The treatment plans of the two areas were compared. ResultsFor dental form, most dentists' treatment plans were categorized as "No intervention" (privileged area: 37.5 %, less-privileged area: 56.53 %, and total: 46.80 %). The percentage of dentists in the privileged area who prescribed cosmetic services was twice that of the less-privileged area (33.33 % versus 17.39 %). The intervention for dental form varied from placing 1 unit of composite veneer to 10 units of ceramic laminates or orthodontics with a wide range of treatment costs ($42.09 to $1079.14). For tooth color, most dentists (privileged area: 62.50 %, less-privileged area: 30.43 %, and total: 46.80 %) were categorized as "Interventionists." For tooth color, the treatment plans varied from scaling and root planing, bleaching, and composite veneer with various costs ($7.19 to $197.84). ConclusionCosmetic treatment plans and expenses varied significantly for a single USP, with many not aligning with the standard treatment plan. Some dentists offered treatments even without a chief complaint from the patient. Dentists in privileged areas were twice as likely to prescribe cosmetic treatments compared to those in less privileged areas. Therefore, cosmetic services necessitate monitoring, establishing clear diagnostic criteria, and implementing educational interventions.

Antimicrobial susceptibility testing of bone and joint pathogens using isothermal microcalorimetry.

The rise in osteomyelitis and periprosthetic joint infections, in combination with increasing life expectancy and the prevalence of diabetes, underscores the urgent need for rapid and accurate diagnostic tools. Conventional culture-based methods are often time-consuming and prone to false-negatives, leading to prolonged and inappropriate antibiotic treatments. This study aims to improve osteomyelitis diagnostics by decreasing the time to detection and the time to an antibiotic susceptibility result to enable a targeted treatment using isothermal microcalorimetry (IMC). IMC measures heat flow in real-time, providing insights into bacterial metabolism without the need for labeling. Using clinical isolates from bone infections, assessing their response to antibiotics through IMC, we demonstrated that IMC could detect bacteria within 4 h and determine antimicrobial susceptibility profiles within 2-22 h (median 4.85, range 1.28-21.78). This is significantly faster than traditional methods. A decision tree, based on antibiotic susceptibility, accurately categorized pathogens, achieving high accuracy (74-100%), sensitivity (100%), and specificity (65-100%). These findings suggest that IMC could redefine diagnostics of bone and joint infections and potentially infections in general, offering timely and precise treatment guidance, thereby improving patient outcomes and reducing health care burdens. Further optimization and clinical validation are needed to fully integrate IMC into routine diagnostics.
