General practitioners (GPs) encounter women suffering from premenstrual symptoms. Often women with premenstrual problems experience little understanding from GPs. Views of GPs will influence their approach to these women and their care. Insight into these views is lacking but could help in designing educational programmes for GPs.

To explore the views of Dutch GPs towards aetiology, diagnostic process, and preferred treatment of premenstrual symptoms.

In 2017, we conducted a qualitative, semi-structured, interview survey among 27 GPs, varying in age, gender, and practice setting.

Important themes emerged from the interviews 'no need for a symptom diary,' 'PMS defined as illness' exclusively in case of disruption of normal functioning, and 'symptomatic treatment' as preferred approach. Most GPs considered PMS to be a physiological phenomenon, with taking history as an adequate diagnostic tool. Almost all GPs regarded a normal cyclical hormonal cycle as causal; many also mentioned the combination with personal sensitivity. Some pointed to a dividing line between physiological condition and illness if women could not function normally in daily life. Lastly, the approach GPs preferred was focussing on relieving symptoms of individual patients. In addition to explaining the hormonal cycle and lifestyle advice, all GPs advocated oral contraceptives, and if necessary psychological support. GPs expressed negative feelings about prescribing antidepressants.

GPs considered physiological changes and personal sensitivity as aetiological factors. We recommend more training to improve GPs knowledge and more insight into the burden of women with PMS. A symptom diary is an essential diagnostic tool for GPs.

Visual function was assessed with full-field electroretinograms (ffERGs), kinetic and chromatic perimetry, multimodal imaging with spectral domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF) with short- (SW) and near-infrared (NIR) excitation lights and adaptive optics scanning light ophthalmoscopy (AOSLO).Results Both siblings had a history of obesity and postaxial polydactyly; P2 had diagnoses of type 1 Diabetes Mellitus, Addison's disease, high-functioning autism-spectrum disorder and -12D myopia. Visual acuities were better than 20/30. Kinetic fields were moderately constricted. Cone-mediated ffERGs were undetectable, rod ERGs were ~80% of normal mean. Static perimetry showed severe central cone and rod dysfunction. Foveal to parafoveal hypoautofluorescence, most obvious on NIR-FAF, co-localized with outer segment shortening/loss and outer nuclear layer thinning by SD-OCT, and with reduced photoreceptors densities by AOSLO. A structural-functional dissociation was confirmed for cone- and rod-mediated parameters. Worsening of the above abnormalities was documented by SD-OCT and FAF in P2 at 3 years. Gene screening identified compound heterozygous mutations in BBS7 (p.Val266Glu c.797 T > A of maternal origin; c.1781_1783delCAT, paternal) in both patients.Conclusions BBS7-associated retinal degeneration may present as a progressive cone-rod dystrophy pattern, reminiscent of both the murine and non-human primate models of the disease. Predominantly central retinal abnormalities in both cone and rod photoreceptors showed a structural-functional dissociation, an ideal scenario for gene augmentation treatments.Activation of peripheral nervous system (PNS) fibres to produce variable tactile and proprioceptive sensations in advanced bidirectional prosthetic limbs relies on neural stimulators with high spatial selectivity, dynamic range and resolution. A multi-channel application-specific integrated circuit (ASIC) is developed for PNS fibre activation using a wide dynamic range (10 nA-5 mA), high-resolution (30 nA step, 100 ns pulse accuracy) current stimulator, dissipating 0.73-2.75 mW at 3 V. The ASIC also enables encoding of external pressure signals via an integrate-and-fire methodology. Electrophysiological data of compound nerve action potentials were recorded for a range of stimulus amplitudes and pulse widths. This data was used to benchmark the performance of the ASIC with a known neural stimulator.Introduction The first mucosal site to encounter inhaled allergen, antigen, and microbes is the upper airway. It must perforce have a rapid system of environmental threat recognition and self-defense. B cells play a critical role in such airway host-defense, tissue surveillance, and immune modulation. Several common upper airway diseases can be defined in the expression of either exaggerated or dysregulated B-cell function within T2-high mucosal inflammatory states.Areas covered In this review, the authors discuss the immunology of allergic rhinitis (AR) and chronic rhinosinusitis with nasal polyps (CRSwNP) in the context of highlighting key aspects of B-cell biology and function. The review is based on the findings of a literature search using the terms B cells, rhinitis, nasal polyps, and rhinosinusitis.Expert opinion Despite the emerging role of B-cell overdrive and dysfunction in upper airway disease, studies are lacking specifics to B cells, particularly in association with sinonasal infection and mucosal inflammation. There is a pressing need to focus on how respiratory inflammation, alongside impaired or exaggerated B-cell function, amplifies and further dysregulates immune signaling pathways in the disease setting of AR and CRSwNP.Malignant melanoma is a life-threatening form of skin cancer with a low response rate to single-agent chemotherapy. Although combined therapies of metformin (MET) and doxorubicin (DOX) are effective in treating a variety of cancers, including breast cancer, their different physicochemical properties and administration routines reduce the effective co-accumulation of both drugs in tumors. Nanoparticles (NPs) have been demonstrated to potentially improve drug delivery efficiency in cancer therapy of, for example, liver and lung cancers. Hence, in this study, we prepared pH-sensitive, biocompatible, tumor-targeting NPs based on the conjugation of biomaterials, including sodium alginate, cholesterol, and folic acid (FCA). As expected, since cholesterol and folic acid are two essentials, but insufficient, substrates for melanoma growth, we observed that the FCA NPs specifically and highly effectively accumulated in xenograft melanoma tumors. Taking advantage of the FCA NP system, we successfully co-delivered a combination of MET and DOX into melanoma tumors to trigger pyroptosis, apoptosis, and necroptosis (PANoptosis) of the melanoma cells, thus blocking melanoma progression. Combined, the establishment of such an FCA NP system provides a promising vector for effective drug delivery into melanoma and increases the possibility and efficiency of drug combinations for cancer treatment.Religious beliefs play a significant role in the lives of victims of domestic violence. Victims find strength in their faith and would rather endure the violence at all costs to keep a family or a marriage together, than to compromise their faith by leaving. This 10 -year study explored the climate of support for victims of domestic violence among Christian clergy and church members between 2005 and 2015. Using a convenience sample, surveys were sent out to congregations in the Upper Midwest in 2005 and 2015. The survey included demographics; two items measuring perception of domestic violence in the congregation and community; six Likert Scale items regarding agreement with statements concerning leaving an abusive marriage; four "Yes-No" items regarding the impact of faith in leaving, support of the congregation, community resources, and clergy as counselors. The clergy's survey had the same questions plus open-ended questions about their skills in counseling victims, their congregation's support for victims, community resources, and beliefs that could impact a victim's choice in leaving. link2 Data were analyzed using descriptive statistics, simple frequencies, and bivariate correlations. Narrative data were analyzed using content analysis. The results of this study indicated that change is slow. Members want their clergy to become more educated in counseling and in speaking about domestic violence from the pulpit. link3 Clergy felt comfortable in making referrals for professional counseling, while the majority of members would prefer counseling with their pastor if they were in a violent relationship. Both clergy and members want to create a safe and supportive environment for victims/survivors of violent relationships. Findings from this study exemplify the need for pastors to remove the silence about domestic violence in their congregations and address the misunderstood social religious beliefs that may bind a victim to the violence.

Understanding the pattern of population risk for coronavirus disease 2019 (COVID-19) is critically important for health systems and policy makers. The objective of this study was to describe the association between neighborhood factors and number of COVID-19 cases. We hypothesized an association between disadvantaged neighborhoods and clusters of COVID-19 cases.

We analyzed data on patients presenting to a large health care system in Boston during February 5-May 4, 2020. We used a bivariate local join-count procedure to determine colocation between census tracts with high rates of neighborhood demographic characteristics (eg, Hispanic race/ethnicity) and measures of disadvantage (eg, health insurance status) and COVID-19 cases. We used negative binomial models to assess independent associations between neighborhood factors and the incidence of COVID-19.

A total of 9898 COVID-19 patients were in the cohort. The overall crude incidence in the study area was 32 cases per 10 000 population, and the adjustedsubsequent health needs.DDIT4 is a mitochondrial and tumor-related protein involved in anti-tumor therapy resistance, proliferation, and invasion, etc. Its expression level increases under the stress such as chemotherapy, hypoxia, and DNA damage. A number of clinical studies have confirmed that DDIT4 can change the behavior of tumor cells and the prognosis of patients with cancer. However, the role of DDIT4 in promoting or suppressing cancer is still inconclusive. This article summarized the four characteristics of DDIT4 including a mitochondria-related protein, interactions with various protein molecules, immune and metabolic cell related proteins and participator in the oxygen sensing pathway, which may be related to the progress of cancer.
