Unmet Needs Discussed on Reddit by Women with Premenstrual Dysphoric Disorder.

Premenstrual dysphoric disorder (PMDD) is a disabling disorder that impacts 1.8 percent to 5.8 percent of menstruating women for 1-2 weeks each month. Many affected women turn to social media platforms for the information and the support they feel that they do not get from other sources. We sought to better understand the most strongly expressed unmet needs of women with PMDD by analyzing their posts and comments on one of the largest social media platforms (Reddit), which has been providing important insights into other medical problems. We searched Reddit using the subreddit title "r/PMDD" for posts from January 2020 through November 2021. To identify the most prevalent issues, we included all written posts with a submission score of at least 5 and at least three comments. Two authors classified each post; inconsistencies were resolved by a third reviewer. Over 800 posts were reviewed; 250 met study criteria; additionally, over 875 comments were evaluated. Four main themes emerged from the analysis: emotional responses to PMDD; unanswered questions women had about the diagnosis and treatment of PMDD; the impact that PMDD had on personal relationships, and, finally, the recommendations women made to others based on their own experience, accurate or not. These themes are detailed in this article to provide insights into what many women with PMDD experience and what their frustrations and misunderstandings are about the condition so that clinicians may better help address women's unspoken questions and correct their possible misinformation.

Isolation and characterization of a Brazilian strain of yellow fever virus from an epizootic outbreak in 2009.

During a series of epizootics caused by Yellow fever virus in Brazil between 2007 and 2009, a monkey was found dead (May 2009) in a sylvatic area in the State of Paraná. Brain samples from this animal were used for immunohistochemical analysis and isolation of a wild-type strain of YFV. This viral strain was characterized, and sequence analyzes demonstrated that it is closely related with YFV strains of the recently identified subclade 1E of the South American genotype I. Further characterization included indirect-immunofluorescence of different infected cell lines and analysis of the kinetics of virus replication and infectivity inhibition by type I IFN. The generated data contributes to the knowledge of YFV evolution and phylogeny. Additionally, the reagents generated and characterized during this study, such as a panel of monoclonal antibodies, are useful tools for further studies on YFV. Lastly, this case stresses the importance of yellow fever surveillance through sentinel monkeys.

First report of yellow fever virus in non-human primates in the State of Paraná, Brazil.

Sylvatic yellow fever is a zoonosis associated mainly with wild animals, especially those in the genus Alouatta, that act as the source of infection. Once infected, these animals pass the disease on to humans by way of an infected mosquito belonging to the genera Aedes, Haemagogus, or Sabethes. The present study is the first report of a case of yellow fever in non-human primates (NHP) in the State of Paraná, Brazil. After the case was diagnosed, several prophylactic measures were adopted to prevent outbreaks of the disease in humans.

Hantavirus infection prevalence in wild rodents and human anti-hantavirus serological profiles from different geographic areas of South Brazil.

Paraná state presents the fourth highest number of accumulated cases of hantavirus pulmonary syndrome in Brazil. To map the risk areas for hantavirus transmission we carried out a study based on rodent trapping and determined the anti-hantavirus seroprevalence in these animals and in the inhabitants of these localities. Overall seroprevalence in rodents and humans were 2.5% and 2.4%, respectively. Eighty-two percent of the seropositive rodents were genetically analyzed. Phylogenetic analyses revealed that hantaviruses from rodent samples cluster with Araucária (Juquitiba-like) or Jaborá hantavirus genotypes. The Jaborá strain was identified in Akodon serrensis and Akodon montensis, whereas the Araucária strain was detected in Oligoryzomys nigripes, Oxymycterus judex, A. montensis, and Akodon paranaensis, with the latter species being identified for the first time as a natural host. These findings expose the complex relationships between virus and reservoirs in Brazil, which could have an impact on hantavirus transmission dynamics in nature and human epidemiology.

Paracoccidioidomycosis in wild monkeys from Paraná State, Brazil.

The aim of this study was to evaluate the seroprevalence of Paracoccidioides brasiliensis infection in wild New World monkeys (Cebus sp. and Alouatta caraya). A total of 93 animals (Cebus sp., n = 68 and Alouatta caraya, n = 25) were captured in the Paraná River basin, Paraná State, Brazil and the serum samples were analyzed by ELISA and immunodiffusion using P. brasiliensis gp43 and exoantigen as antigens, respectively. The seropositivity observed by ELISA was 44.1% and 60% for Cebus sp. and A. caraya, respectively, while by immunodiffusion test Cebus sp. showed positivity of 2.9% only. No significant difference was observed in relation to age and sex. This is the first report of paracoccidioidomycosis in wild capuchin monkeys and in wild-black and golden-howler monkeys. The high positivity to P. brasiliensis infection in both species evaluated in our study and the positivity by immunodiffusion test in Cebus sp. suggest that natural disease may be occurring in wild monkeys living in paracoccidioidomycosis endemic areas.
