Defining Dysphoric Milk Ejection Reflex: Using Premenstrual Dysphoric Disorder As A Framework For Proposing Preliminary Diagnostic Criteria

Faculty, Staff and Students Publications

Dysphoric Milk Ejection Reflex (D-MER) is a distinct neurobiological condition characterized by negative alterations in mental state in response to milk letdown during lactation. Symptoms vary by patient and can include feelings of sadness, anxiety or agitation. Importantly, the symptoms are brief, typically lasting no more than 5 minutes. Prevalence has been found between 6 and 27% of lactating women, but studies show heterogeneity, due in part to inconsistent definition. D-MER is not currently classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD), which presents a challenge for researchers of the …

Hypertriglyceridemia In New-Onset Type 1 Pediatric Diabetes, Sarah K Lyons, Aikaterini A Nella

Faculty, Staff and Students Publications

Hypertriglyceridemia (HTG) in the setting of newly diagnosed diabetes is common in both adult and pediatric populations, as insulin deficiency promotes lipolysis and impairs triglyceride (TG) clearance. Severe HTG (defined as TG levels above 1000 mg/dL) in pediatric patients with new-onset type 1 diabetes mellitus (T1D) is rare; the true incidence and sequela of this phenomenon have not been well characterized. We present a single-center experience on severe HTG in pediatric patients with new-onset T1D between 2013 and 2022 and summarize the cases previously reported in the literature. Our cases display variability in their presentation and in their association with …

Background and objectives: Physical abuse is a common cause of morbidity in infants but is often missed in those with medically minor injuries, increasing the risk for escalating violence. Our objective was to compare the prevalence of abuse-specific injuries among infants with and without prior injuries.

Methods: This is a retrospective, multicenter study of infants (aged < 12 months) undergoing child abuse pediatrics provider (CAP) consultation for suspected physical abuse between 2/2021 and 12/2022 at 10 participating US centers. Encounters were dichotomized into those with and without history of prior injury. The groups were compared for rates of diagnostic screening and prevalence of abuse-specific injuries. The association of prior injuries with identification of abuse-specific injury was assessed using logistic regression controlling for demographics and presence of prior injury.

Results: We identified 2352 eligible encounters (median age: 4.2 months), of which 13% had a history of prior injury. In infants who underwent diagnostic testing, injury identification was significantly higher in those with prior injury (45% vs 22%, P < .05). Adjusting for patient characteristics, the presence of prior injury in infants was associated with higher odds of at least 1 type of abuse-specific injury being identified, compared with those without prior injury (adjusted odds ratio = 2.81, 95% CI = 2.10-3.76).

Conclusion: Infants with prior injury …

A Case Of Igg4-Related Disease Manifesting As Extensive Abdominal Periarteritis And Membranous Nephropathy, Successfully Controlled With Low-Dose Steroid Therapy Without Relapse Or Complications, Minami Matsumoto, Shinya Yamamoto, Hideki Yokoi, Sho Koyasu, Shigeo Hara, Takahiro Tsuji, Minamiguchi Sachiko, Motoko Yanagita

Faculty, Staff and Students Publications

Introduction: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease that can affect nearly every organ system, including blood vessels and the kidney. IgG4-related vascular lesions mainly involve the aorta, and the dominant renal manifestation is tubulointerstitial nephritis (TIN). Here, we report a case of IgG4-RD demonstrating extensive abdominal periarteritis and membranous nephropathy (MN).

Case presentation: The patient was a 71-year-old man with peptic ulcer who developed nephrotic syndrome, with a low serum albumin level (1.8 g/dL), massive urinary protein (6.1 g/day), and high serum IgG4 level (435 mg/dL). Computed tomography images revealed soft tissue mass around the medium-sized abdominal arteries. …

Glomerular diseases with organized deposits can be classified into various etiologies. A diagnostic algorithm based on clinical and pathological findings has been proposed. However, some cases cannot be diagnosed using existing algorithms. Here, we report the case of a 77-year-old man diagnosed with membranoproliferative glomerulonephritis (MPGN) with striated ultrastructural deposits, micro-filament-like substructures with straight bands arranged in parallel in the subendothelial space by two sequential renal biopsies. His examinations and clinical findings were incompatible with known glomerular diseases with organized deposits. Dialysis was initiated 10 months after the second biopsy procedure. Furthermore, we report the first mass spectrometry analysis of …

Temperate grasslands are one of the major biomes of the global biosphere, but underrepresented in the global protected area network. They are complex ecosystem, which adapted in co-evolution of vegetation and migratory large herbivores in interactions with small mammals like rodents, with predatory mammals and divers birdlife, with insects and soil organisms to extreme climate conditions in continental, semi-arid regions. The original distribution covered large territories in South- America (“pampa”), in North-America (“prairie”), and in Eurasia (“steppe”).

Most of them are destroyed by conversion or degraded by overgrazing. Mongolia is the worldwide only country, where temperate grasslands survived in large …

Model Of The Distribution Of The Nomion Apollo (Lepidoptera: Papilionidae) Butterfly In Mongolia, Gantigmaa Chuluunbaatar, Richard P. Reading

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The distribution of the Nomion Apollo Butterfly (Parnassius nomion FISCHER von WALDHEIM, 1823) remains poorly studied, especially in Mongolia. We studied the Nomion Apollo in Mongolia to detect locations within different habitat types, create a distribution map for populations of the species, describe preferred vegetation communities, and assess the environmental factors that influence the species’ distribution. We surveyed 10 sites with known populations of Nomion Apollo butterflies in northern Mongolia and sampled the vegetation communities where we found butterflies. We then created a distribution map of Nomion Apollo using the program MaxEnt/3.4.1 based on the relationship between the abundance …

Genetic Insights Into The Diversity Of Mongolian Oedipodinae: A Multi-Gene Approach, Lara-Sophie Dey, Davaa Lkhagvasuren, Martin Husemann

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This study presents an examination of the genetic diversity of Oedipodinae, a subfamily of grasshoppers, with focus on their distribution and variation in Mongolia. Utilizing a multi-gene approach, we analyze genetic data from various Oedipodinae species from Mongolia, aiming to improve our understanding of their phylogenetic relationships. This research not only enhances our knowledge of Oedipodinae diversity in Mongolia, but also underscores the importance of genetic studies in unraveling the complexities of sequence and potentially species evolution. Despite the implementation of a multi-gene approach in this study, the results indicate a lack of clear phylogenetic differentiation within the tribes Sphingonotini …

Weather And Climate In Ulaanbaatar (Central Mongolia) Between 1980 And 2024, Michael Walther

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In a 40-year comparison, 2024 was not a record temperature year as stated for Central Europe (Tagesschau 2024). It was 0.5°C warmer than the 40-year average. While winter temperatures were slightly colder, summer temperatures were significantly warmer. The number of days with extreme coldness (< -25°C) increased, while the number of days with temperatures warmer than -25°C decreased. Precipitation was again very high in 2024 and was many times higher than in the years 1981-2021. Extreme rainfall events in particular increased in 2023 and 2024.

Precipitation of more than 30 mm fell in 24 hours, which led to catastrophic economic damage. Precipitation has risen continuously since 2021. Between 1995 and 2011, very negative forecasts for the drinking water supply were made during a period of prolonged negative water precipitation.

The reasons for the extremely sharp increase in precipitation are a …

Middle Eocene through Late Miocene lagomorphs are reported from more than 40 localities of the Zaysan Basin, Kazakhstan. The lagomorph fauna includes 21 taxa of 12 genera. Eight genera are central Asian endemics, two genera are European forms, and one genus (Alloptox) has a Eurasian distribution. These data allow correlation of the lagomorph faunas of the Zaysan Basin with contemporaneous faunas of Mongolia, Northern China and some European regions.

Seasonal Variations In Vocal Frequency And Volume Of Mongolian Marmots (Marmota Sibirica Radde, 1862): Insights From Cooperative Breeding In Songinokhairkhan Mountain, Sainzorigt Munkh-Orgil, Nyamsuren Batsaikhan, Gerelt Gan-Ochir, Amarsanaa Zolzaya, Altangerel Tsogtsaikhan Dursahinhan

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In the Songinokhairkhan Mountain region of Mongolia, we examined the vocal patterns of Mongolian marmots, Marmota sibirica (RADDE, 1862), across two seasons. The study aimed to understand how cooperative breeding, a system where certain individual marmots assist others in reproduction, influences their vocalization. Our acoustic data revealed differences in vocal frequency and volume between the post-mating period in April and May, and pup emergence time in July. Specifically, marmots vocalized more frequently during early mornings, with variations observed in call patterns and volume between the two study periods. These findings provide crucial insights into how marmots adjust their communication strategies …

The Current Status Of The Red Deer (Cervus Elaphus Sibiricus) Population In Mongolia

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

One of the most commonly portrayed animals in the petroglyphs, rock carvings, and cave paintings found throughout Mongolia's vast steppes is the red deer. It’s population in Mongolia declined precipitously in the early years of the 20th century. For the first time, a nationwide comprehensive census of the red deer population was conducted, covering all known habitats across Mongolia. A combination of methods was employed to estimate population size, including line transect surveys, point counts, rutting call responses, and the recording of indirect signs such as tracks and scat pellets. Using habitat suitability modeling on a province-by-province basis, the distribution …

New Record Of Gvosdevilepis Fragmentata (Gvosdev, 1948) (Cestoda: Hymenolepidinae) From Lepus Tolai (Lagomorpha: Leporidae) In Mongolia, Allison R. Hearty, Nyamsuren Batsaikhan, Gábor R. Rácz, Scott L. Gardner

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Three individuals of Lepus tolai (Lagomorpha: Leporidae) were collected from southern Mongolia between 2009 and 2010 and examined for endoparasites. Gvosdevilepis fragmentata (GVOSDEV, 1948) (Cestoda: Hymenolepidinae) was identified from one male hare. Gvosdevilepis fragmentata is a known parasite of Leporidae in Europe and Asia. This is the first record of Gvosdevilepis fragmentata from Mongolia.

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Caves are important habitats for a variety of different species, such as bats. Many species of bats are cave obligates, specifically in temperate zones, spending almost half the year hibernating in them. There are hundreds of caves identified in Mongolia, where past studies have mostly focused on cave morphology, geology, and archeology. However, a comprehensive assessment of cave-dwelling bats has not yet been conducted. In this study, abundance, species richness, population size, and identification of key sites of cave-dwelling bats in Mongolia was conducted using observations gathered over the past 15 years (2009–2024). It was found that bat population size …

It included several species of the genus Myotis as well as representatives of the genera Eptesicus, Vespertilio and Plecotus. The most frequently captured species were Myotis davidii, Eptesicus nilssonii and Plecotus ognevi. The genus Myotis also dominated the recordings, although species …

Bat Ectoparasites Of Mongolia, Part 4, Ingo Scheffler, Dietrich Dolch, Klaus Thiele, Dalannast Munkhnast, Jargalsaikhan Ariunbold, I. Bolorchimeg, B. Gärtner

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The field excursions of 2019 and 2023 provided new data on ectoparasites of 14 bat species from different habitats of the taiga, steppes and deserts. A total of 27 species of ectoparasites were found on these bats, whose abundances and host preferences are described. This results in genus- and species-specific combinations of the ectoparasites present on the respective host species. The infestation with ectoparasites (P-load) differs considerably between bat species. Within a species, the infestation is much more dependent on the parasite load of the respective maternity roost than on factors such as sex, age or body constitution.

In 1999, four participants from Brandenburg also took part in a mammal field excursion through Mongolia organized by Professor Michael Stubbe from the Martin Luther University and Professor R. Samjaa from the National University of Mongolia in Ulaanbaatar. They discovered the bats of Mongolia as a fascinating field of work and established contacts with Mongolian colleagues, with whom they organized bat-oriented research expeditions under the motto "Chiroptera Mongolia." These eight expeditions, organized on a voluntary basis and privately funded over a period of twenty years, were eventful and scientifically productive.
