Selective estrogen receptor modulators (SERMs) are synthetic molecules that bind to the estrogen receptor and can have agonistic activity in some tissues while being estrogen antagonistic in others. While not all SERMs are clinically available in all parts of the world, this article will review preclinical and clinical effects of various SERMs on bone. These include tamoxifen, used as adjuvant therapy in breast cancer patients as well as for breast cancer prevention; raloxifene, approved for osteoporosis prevention and treatment as well as breast cancer prevention; bazedoxifene, approved for prevention of osteoporosis and also in combination with conjugated equine estrogen for treatment of vasomotor symptoms and prevention of bone loss in postmenopausal patients; and ospemifene, approved for treatment of dyspareunia due to vulvovaginal atrophy/genitourinary syndrome of menopause. Thus, these SERMs are a diverse group of estrogen agonist/antagonists that seem to have class effects in the bone and breast, although the amount of clinical trial data is quite variable. However, there does not seem to be the same unidirectional class activity in tissues like the uterus or vagina. Health-care providers should be cognizant of all available information in helping patients make the best possible shared decision-making choices.Melanoma in humans and dogs is considered highly immunogenic; however, the function of tumor-infiltrating lymphocytes (TILs) is often suppressed in the tumor microenvironment. In humans, current immunotherapies target checkpoint molecules (such as PD-L1, expressed by tumor cells), inhibiting their suppressive effect over TILs. The role of PD-L2, an alternative PD-1 ligand also overexpressed in malignant tumors and in patients with anti-PD-L1 resistance, remains poorly understood. In the current study, we evaluated the expression of checkpoint molecule mRNAs in canine melanoma and TILs. Analysis of checkpoint molecule gene expression was performed by RT-qPCR (real-time quantitative polymerase chain reaction) using total RNA isolated from formalin-fixed and paraffin-embedded melanomas (n = 22) and melanocytomas (n = 9) from the Virginia Tech Animal Laboratory Services archives. Analysis of checkpoint molecule expression revealed significantly higher levels of PDCD1 (PD-1) and CD274 (PD-L1) mRNAs and an upward trend in PDCD1LG2 (PD-L2) mRNA in melanomas relative to melanocytomas. Immunohistochemistry revealed markedly increased numbers of CD3+ T cells in the highest PD-1-expressing subgroup of melanomas compared to the lowest PD-1 expressors, whereas densities of IBA1+ cells (macrophages) were similar in both groups. CD79a+ cell numbers were low for both groups. As in human melanoma, overexpression of the PD-1/PD-L1/PD-L2 axis is a common feature of canine melanoma. High expression of PD-1 and PD-L1 correlates with increased numbers of CD3+ cells. Additionally, the high level of IBA1+ cells in melanomas with low PD-1 expression and low CD3+ cells levels suggest that the expression of checkpoint molecules is modulated by interactions between T cells and cancer cells rather than histiocytes.In Gilgit, capital of the Gilgit-Baltistan region in northern Pakistan, leucorrhea - vaginal discharge known in the vernacular as safaid pani, or 'white water' - serves as both a medical diagnosis and signifier of the chronicity of the reproductive, social, and emotional burdens endured by women. While ethnomedical providers explained safaid pani as resulting from relatively benign forms of 'weakness', which required minimal dietary or ethno-botanical recourse, allopathic physicians approached discharge as evidence of numerous pathologies that necessitated protracted and sometimes also expensive treatments. Physicians' clinical assessments were not solely biomedical, but also integrated informal folk and formal ethnomedical theories of causation. Clinical diagnoses that affirmed leucorrhea as a pathophysiology substantiated women's belief that it was proof of the destructive effects of sustained social inequity, peril, and distress on the body, and the uterus in particular. Women and their treating providers recognized the power of the (dys)functional uterus to not only threaten women's reproductive wellness but also their social, marital, and familial status, which hinged on their ability to become pregnant and give birth, to sons especially. Because of the ailing uterus's expansive importance, weeping wombs served as a potent source for women's claims making and calls for attention and care.
Vena cava filters have been used as a primary means to prevent symptomatic pulmonary embolism (PE) in trauma patients who cannot be anticoagulated after severe injury, but the economic implications for this practice remain unclear.

Using a healthcare system perspective to analyze the
primary outcome of the da Vinci trial, we report the cost-effectiveness of using vena cava filters as a primary means to prevent PE in patients who have contraindications to prophylactic anticoagulation after major trauma.

Of the 240 patients enrolled, complete, prospectively collected, hospital cost data during the entire hospital stay - including costs for the filter, medical/nursing/allied health staff, medical supplies, pathology tests, and radiological imaging - were available in 223 patients (93%). Patients allocated to the filter group (
= 114) were associated with a reduced risk of PE (0.9%) compared to those in the control group (
= 109, 5.5%;
= 0.048); and the filter's benefit was more pronounced among those who could not be anticoagulated within 7 days (filter 0% vs control 16%, Bonferroni-corrected
= 0.02). Overall, the cost needed to prevent one PE was high (AUD $379,760), but among those who could not be anticoagulated within 7 days, the costs to prevent one PE (AUD $36,156; ~ USD $26,032) and gain one quality-adjusted life-year (AUD $30,903; ~ USD $22,250) were substantially lower.

The cost of using a vena cava filter to prevent PE for those who have contraindications to prophylactic anticoagulation within 3 days of injury is prohibitive, unless such contraindications remain for longer than 7 days. (

The coronavirus disease 2019 (COVID-19) pandemic's impact on vascular procedural volumes and outcomes has not been fully characterized.

Volume and outcome data before (1/2019 - 2/2020), during (3/2020 - 4/2020), and following (5/2020 - 6/2020) the initial pandemic surge were obtained from the Vascular Quality Initiative
. Volume changes were determined using interrupted Poisson time series regression. Adjusted mortality was estimated using multivariable logistic regression.

The final cohort comprised 57,181 patients from 147 US and Canadian sites. Overall procedure volumes fell 35.2% (95% CI 31.9%, 38.4%,
< 0.001) during and 19.8% (95% CI 16.8%, 22.9%,
< 0.001) following the surge, compared with presurge months. Procedure volumes fell 71.1% for claudication (95% CI 55.6%, 86.4%,
< 0.001) and 15.9% for chronic limb-threatening ischemia (CLTI) (95% CI 11.9%, 19.8%,
< 0.001) but remained unchanged for acute limb ischemia (ALI) when comparing surge to presurge months. Adjusted mortality was significantly higher among those with claudication (0.5% vs 0.1%; OR 4.38 [95% CI 1.42, 13.5],
= 0.01) and ALI (6.4% vs 4.4%; OR 2.63 [95% CI 1.39, 4.98],
= 0.003) when comparing postsurge with presurge periods.

The first North American COVID-19 pandemic surge was associated with a significant and sustained decline in both elective and nonelective lower-extremity vascular procedural volumes. When compared with presurge patients, in-hospital mortality increased for those with claudication and ALI following the surge.

POI results in adverse effects on the skeleton and central nervous system as well as disturbances of metabolic and cardiological factors that predispose to a major increased risk of cardiovascular disease (CVD). This article reviews the effects of the premature loss of ovarian function on lipids and lipoproteins, glucose and insulin metabolism, body composition, hemostasis and blood pressure, together with effects on the development of metabolic syndrome and diabetes mellitus. The article examines the effects of POI on vascular endothelial function and inflammation that result in arterial disease, and reviews the effects of hormone replacement therapy (HRT) on these various metabolic processes and on cardiovascular outcomes. It is essential that women with POI receive hormonal treatment to help prevent the development of CVD, and that this treatment is continued at least until the normal age of menopause. It appears that HRT has a more favorable effect than the combined oral contraceptive, but larger clinical trials are needed to establish the optimal treatment. Other therapeutic measures may need to be added to correct existing metabolic abnormalities and, in particular, attention to lifestyle factors such as diet and exercise must be encouraged.
To develop a best practice document for the management of postmenopausal vulvovaginal atrophy (VVA).

Literature review carried out using clinical terms, treatments or interventions and comorbidity related to VVA.

There is a wide variety of interventions that may produce temporal benefits for VVA. However, there are significant limitations in scientific publications concerning VVA and related issues, including variable outcome evaluations, variability in population age range, and small, often underpowered sample sizes. Therapeutic management of VVA should follow a sequential order, considering women's age, symptoms, general health as well as treatment preference. Beneficial options include lubricants, moisturizers, vaginal estrogens (estradiol, estriol, promestriene, conjugated estrogens), androgens, prasterone, and laser application. In women with general menopausal symptoms who are candidates for systemic hormone therapy, the lowest effective dose should be used. selleck chemicals llc Oral ospemifene is an effective selective estrogen receptor modulator to treat VVA. Systemic androgens have a limited role. Although laser procedures are commonly used, at this moment the International Society for the Study of Vulvovaginal Disease does not endorse its use out of the setting of clinical trials. Pelvic floor muscle training improves blood flow and elasticity of the vulvovaginal tissue. In breast cancer survivors, moisturizers and lubricants are first line therapy. However, limited absorption of low/ultra-low doses of estrogens suggests safety, especially in women under treatment with aromatase inhibitors. As clinical practice and available preparations vary between countries this text should be adapted to local circumstances.

There is a wide range of therapeutic options to individualize VVA treatments.
