Introduction: The effectiveness of the uterine tourniquet alone for securing hemostasis during abdominal myomectomy remains  debatable; however, its combination with uterine compression though popular has very scanty documented evidence of hemostatic  efficacy.
Aim: To determine the effect of uterine incision compression (UIC) combined with tourniquet on operative blood loss associated  with abdominal myomectomy.
Materials and Methods: A multicenter randomized double blind, controlled trial involving 184  participants randomized into two groups: 92 in the UIC and 92 in the control arm. UIC was administered in the interval from release of  the uterine tourniquet to palpation of contraction. Data were analyzed using the Statistical Package for the Social Sciences (SPSS), version  21.
Results: The mean intraoperative blood loss was lower in the UIC group (951.41 ± 362.32 mL) than in the control group  (1051.30 ± 427.77 mL), but did not reach statistical significance (p = 0.125). The observed mean duration of myomectomy was, however,  longer among the controls (152.95 ± 32.67 min, compared with 119.70 ± 23.96 min, p = 0.001). The control group also had significantly higher rates of deployment of additional hemostatic measures (OR = 4.68, 95% CI = 2.304–12.784, p = 0.001), occurrence of postoperative  pyrexia (OR = 1.65, 95% CI = 1.256–2.154, p = 0.002), and greater mean postoperative blood loss (p = 0.003).
Conclusion: Although no  statistically significant difference occurred in intraoperative blood loss, adjunctive UIC was useful in reducing operating time and  postoperative blood loss

Published: July 2024

Background: Men who have sex with men (MSM) face a high burden of sexually transmitted infections, hence form a vital target population for public health response. The primary objective of this study was to determine the frequency and predictors of selected sexually transmitted infections among men who have sex with using pre-exposure prophylaxis (PrEP) in Kiambu County.
Materials And Methods: An analytical cross-sectional study design was and MSM currently using PrEP were enrolled. Venue-based sampling was adopted and a sample size of 157 respondents was included in the survey. A total of 4 key informant interviews were conducted and 3 focus group discussions comprising 11, 8 and 7 members respectively provided additional information regarding PrEP use and sexually transmitted infections (STI). Data was analyzed using Stata version 17.
Results: STI prevalence was 37.5%, with the highest rates observed for co-morbidities of chlamydia and gonorrhoea at 47.9%, and genital warts at 31.3%. Other prevalent STIs included chlamydia (10.4%), chlamydia with genital warts (4.2%), syphilis (4.2%), and gonorrhea (2.1%).. Missing to take PrEP was not significantly associated with STI prevalence [p=0.093]. However, the regression analysis indicated significant associations between STI prevalence and the type of sexual typologies for combined anal, oral and bisexual sex, (p=0.022), similar to anal and bisexual (p=0.008) and anal and oral (p=0.011). Failing to notify one’s partner of testing positive for an STI also had a significant association with STI prevalence [p=0.013].
Conclusion: The study concluded that STI prevalence among MSM on PrEP was associated with sexual typologies of anal, oral, and bisexual sex, and failing to notify one’s partners after turning positive for an STI.
Recommendation: The study recommends the Ministry of Health and partners reach MSM on PrEP with health services geared to lower the STI transmission rates and with persistent messaging encouraging continuous condom use and sharing of best strategies for and importance of partner notification.

Published: July 2024

Background: Despite global efforts to reach a 95% viral suppression rate among people with HIV on Antiretroviral therapy (ART), progress has been slower for Adolescents living with HIV (ALHIV). Therefore, identifying the household factors associated with viral suppression among ALHIV could ensure zero HIV transmission and reduce the risk of opportunistic infections, drug resistance and AIDS.
Materials And Methods: Using a cross-sectional survey design with a quantitative approach, data was collected from 263 adolescents during their routine clinic visits at a large HIV comprehensive care clinic namely Rafiki Center and Module 4 clinic based at Academic Model Providing Access to Healthcare (AMPATH). Respondents were identified using a systematic random sampling technique. A structured questionnaire was used to assess the demographic and household factors associated with viral suppression. The viral load data was obtained from the Electronic Medical Records.
Results: Of the 263 adolescents, 85.6% (n=225) were virally suppressed. Participants who talked freely with caregivers/parents about HIV status (AOR=3.10, 95%CI=1.40-8.92), getting reminders from their caregivers to take ART (AOR=2.15, 95%CI=1.59-5.22) and were getting financial support to facilitate their transport to the facility (AOR=2.33, 95%CI=1.82-6.65). Additionally, those who joined a social support group (AOR=3.82, 95%CI=1.20-12.15) and who took less than 60 minutes to reach the health facility (AOR=3.16, 95%CI=1.29-7.74) had higher odds of viral suppression. Participants whose level of education was at least secondary school (AOR=6.87, 95%CI=2.40-19.64) and who lived with both parents (AOR=5.0, 95%CI=1.66-15.09) had higher odds of viral suppression. The odds of becoming virally suppressed were lower among older adolescents (AOR=0.62, 95%CI=0.47- 0.82).
Conclusion: Viral suppression levels approached but did not meet 2030 targets. Stable living conditions, strong family relationships, communication, and social support were linked to improved viral suppression. Integrating these household factors into HIV care is crucial for enhancing viral suppression among ALHIV. Implementing family empowerment models through further studies can inform effective policy interventions.

The study was carried out to investigate the concentration of major and trace metals in shaly and calcareous soil and their uptake in cassava plant parts in order to compare the levels of this metals in both soils as well as the cassava plant growing on the soil. Soil samples (0-30 cm and 30-60 cm) depth and cassava plants (leaves, stems and tubers) were collected from cultivated farm lands and analyzed for major and trace metals. (Ca, K, Al, Na, Fe, Cu, Zn, Pb, Co and Mo) using inductively coupled plasma mass spectrometery (ICP-MS). The pH and L01 of the soil sample were also measured. Results show that calcareous soils were moderately acidic to basic while shaly soils were acidic to neutral. The organic matter content were relatively higher in surface soils than subsurface soils. Levels of metals were generally higher in shaly soils compared to calcareous soils except for Ca, Na, and Mo. Values of enrichment factors revealed deficiency to minimal enrichment (Ef<2) of Al, K, Ca, Fe and Na, moderate enrichment (Ef2-5) of Cu, Zn, and Co and significant enrichment (Ef5-20) of Mo and Pb for shaly soils. In the case of calcareous soils, minimal enrichment was noticed for Al, Fe, K, Cu and Ca while Na, Zn, Pb and Co showed moderate enrichment with only Mo indicated very high enrichment. The principal analysis for cancerous and shaly soils in the study area indicate that the main source of metals are environment, geochemical and anthropogenic activities.

Authors: K Olafiranye , S A Opeloye , J O Amigun , O M Adeoye
Published: July 2024

Deepwater depositional elements are the building blocks of submarine systems and represent the basic mappable elements in seismic volumes. This study utilizes good quality 3-D seismic data of 300 km2 areal coverage in water depth of 500 m to characterise the planform morphology and distribution of channel elements in the upper slope of deepwater western, Niger Delta. The seismic interval of interest (between 500 and 1650 milliseconds two-way time (TWT), informally termed ‘Channel System’, was subdivided into six (6) seismic units - Intra Channels (IC) 1, 2, 3, 4, top channel system (TCS), and undeformed hemipelagites (UH). Seismic interpretation was carried out for each of the seven horizons to derive their respective subsurface TWT maps. The median surface between two successive maps were derived to capture their internal architecture within the seismic units based on reconditioning the seismic volume semblance attribute. The resulting semblance attribute maps, from the Intra Channel 1 (IC1) unit through the overlying units to the Undeformed Hemipelagites (UH) unit presented an enhanced planform morphology of various NE-SW trend channels. The IC1 is imprinted with three channels of varying sinuosity, IC2 is characterised by one non-sinuous channel and one sinuous channel, IC3 indicates three non-sinuous channel, and one sinuous channel, IC4 and the TCS’ are both characterised by several sub-parallel channels and one sinuous channel, while the topmost UH unit displayed several straight slope gullies upslope with imprint of one precursor sinuous channel. The identified channel forms vary in morphology, sinuosity and distribution both spatially and across the stratigraphic succession in the upper slope. The progressive temporal disappearance of the channels is linked to the associated background hemipelagites that acted as blankets over the precursor channels.

Published: July 2024

This paper examines some of the most profoundly complex factors that influenced the 2023 general election process and its outcome in Nigeria. Methodologically structured in qualitative method, it drew its data from secondary sources; textbooks, journals, internet, official INEC website and from over 26 Nigerian daily Newspapers. These were contently analyzed within the context of the subject matter under consideration. Findings reveal that despite the optimism generated by INEC’s improved electoral technologies; Bi-modal Voting Accreditation System(BVAS) and INEC’s Results Viewing Portal(IREV) which aimed at guaranteeing the transparency of electoral results, the 2023 general elections was held amid difficult environment characterized by wide spread insecurity and uncertain governmental policies, operational and logistics challenges, malfunctioning electoral technologies, violence and intimidation, electoral fraud, lack of transparency in communication and collation of results, inadequate infrastructure among others. From these findings the paper recommended the imperatives of strengthening the institution of INEC by making it truly independent and in this way, it can guarantee a fraud-free election which will be a reflection of the will of Nigerians. This will bolster democracy and foster a more stable future elections in the country.

Authors: Glory Eteng Bassey , Patrick Archibong Esther , Obue Eyang Brian , Nkpoyen Festus
Published: July 2024

Female is a strategic development priority. Better educated women tend to be healthier than uneducated women, participate more in the formal labor market, earn more income, give birth to fewer children, marry at a later age, and provide better health care and education to their children. The paper posits that academic integrity is very crucial for the female pursuit of academic knowledge in realizing their potentials. This makes the connection between female education and academic integrity significant. The values of academic integrity are expected to be promoted or re-cultivated in the school. Three research questions and three hypotheses were formulated and tested in the study.  Relevant and related literature was reviewed. The study adopted the survey research design. The sample for this study consisted of 750 female undergraduate students selected from three tertiary institutions in the study areas. In analyzing the obtained data, the Chi-square inferential statistics was adopted. The findings revealed that female education for social development is significantly moderated and modulated by academic integrity and reduced academic dishonesty in terms of cheating, plagiarism, unethical behavior, purchase of research papers and falsification of research data among lecturers and students. It was concluded that education is an engine of growth and key to the development of every society based on its quality. Hence the paper recommended that in view of the unique role of our women in facilitating social development through political participation, fertility regulation and labour force engagement, academic integrity should be re- cultivated in the tertiary education system.

Authors: Ogbimi Ewere , Kogha N , Emma-Nzekwue N , Emagboron SO
Published: July 2024

Background: Central nervous infections can present with or be complicated by acute infarctions similar to those seen in acute ischaemic stroke. Multiple and extensive cortical infarctions is an uncommon complication of acute bacterial meningitis in the young adult population and is associated with a poor prognosis.
Findings: We present a case of a 41year old male bar attendant with extensive cortical infarctions post-acute meningoencephalitis. He was referred to our facility with a history of sore throat, fever, headache, neck pain and irrational behaviour. Initial Brain Computerised Tomography scan (CT) at presentation was normal, however a throat swab had revealed non-haemolytic streptococci and Cerebrospinal fluid analysis showed growth of streptococcal species (spp.). He was commenced on empirical intravenous antibiotics. A repeat brain CT scan ordered for after a week on admission due to patient’s deteriorating state showed extensive multiple cortical and subcortical infarctions bilaterally involving the pons, cerebellar, and cerebral cortex. Despite intensive management, we lost the patient after eighteen (18) days on admission.
Conclusion: The presence of multiple infarctions portends a worse prognosis and should prompt more vigilance in the management of such patients.

Authors: Abdullahi A.K. , Olowosulu A.K. , Allagh T.S.
Published: July 2024

Background: Due to its simplicity and cost-effectiveness, direct compression has become the approach most frequently used to create  tablet. Nonetheless, the active pharmaceutical ingredient should have acceptable flow and good compaction qualities in order to use  direct compression in tablet manufacture. Crystallo coagglomeration (CCA) technique has shown to be efficient in improving the earliest  stages of tablet manufacture. By combining crystallization (primary particles design) and agglomeration (secondary particles design), it increases the product’s added value.
Objectives: This study exploits the CCA approach to boost the physico-mechanical and tableting properties of metronidazole tablet.
Methods: Metronidazole co-agglomerates was formulated with hydrophilic polymers using CCA technique. The dilution potential of the  produced agglomerates was assessed to obtain suitable concentration that was used to prepare metronidazole tablet by direct  compression method after which the tablet properties were evaluated.
Results: Metronidazole agglomerate powder had a very good  flow rate and angle of repose, low bulk and tapped densities as well as improved Carr’s compressibility index, 15.00±0.14% and Hausner’s  ratio 1.18±0.03 compared to pure metronidazole (27.54±0.14% and 1.38±0.04 respectively). The CSFR/Dt ratio for batches F3  and F4 showed higher compactability and functionality. The dissolution profiles of batches F3 and F4 of metronidazole exhibited  improved dissolution behaviour than pure drug containing batches (batches F1 and F2).
Conclusion: The CCA technique yielded  metronidazole with increased particle size and compactability resulting in excellent flowability and packability due to reduced inter- particulate friction, which exhibited improved compressibility, dilution potential, disintegration and dissolution rate.

Background and objectives: Various parts of Mimosa pigra (MPG) are used in traditional medicines to treat convulsive disorders. The objective of this study was to investigate the anticonvulsant properties of Mimosa pigra ethanol root extract (EREM).Methods: The acute toxicity of the extract was investigated using OECD 423 protocol of 2002. The anticonvulsant properties of EREM at  200,400 and 800 mg/kg were evaluated using Maximal Electroshock Test (MEST) in chicks; strychnine (SCN-) and pentylenetetrazole (PTZ)-induced seizures in mice.Results: The extract at 400 and 800 mg/kg significantly (p<0.05) prolonged the mean onset of clonic and tonic convulsions in mouse  model of SCN-induced seizure. In PTZ-induced seizure, the extract at 400 mg/kg significantly (p<0.05) increased the mean onset of clonic seizure, while at 800 mg/kg, there was significant (p<0.05) prolongation in the mean onset of clonic and tonic seizure compared to  control. The extract did not protect the chick against MEST but significantly (p < 0.05) reduced the mean recovery time at the of 200, 400 and 800 mg/kg. The extract offered 60 and 100% protection at 400 and 800 mg/kg respectively in SCN-induced seizure. Similarly, EREM  offered 20 and 40% protection at 400 and 800 mg/kg respectively in PTZ-induced seizure. Diazepam (10 mg/kg), a reference drug significantly (p<0.05) prolonged the onset of clonic-tonic seizure and protected against SCN-, and PTZ-induced convulsion in mice.Conclusion: These findings indicated that EREM may possess anticonvulsant activity in SCN-, and PTZ-induced seizure in mice. Thus, lend scientific credence to the anticonvulsant claim of EREM in ethnomedicine.

La presente investigación tiene como objetivo identificar si existe una relación entre los ataques de canes callejeros y la responsabilidad civil de una entidad del estado, como lo es la Municipalidad de Villa el Salvador. En este estudio de enfoque cualitativo y cuyo diseño de estudio fue de Teoría Fundamentada, se analiza detenidamente los principios legales, normativas vigentes y la jurisprudencia aplicable que determinan la obligación del Estado de resarcir los perjuicios ocasionados a ciudadanos.
Se realizaron entrevistas a distintos funcionarios y abogados expertos en la materia, con el fin de esclarecer los fundamentos legales y posibles mejoras a la vigente Ley 27596 además se evalúa la inexistencia de medidas preventivas implementadas por la municipalidad del distrito y de un mecanismo de identificación y registro de canes, entre otros. La conclusión a la que arribamos es que; existe una responsabilidad civil por parte de la Municipalidad de Villa El Salvador para ciertos casos y dependiendo de la gravedad del ataque, para determinar ello se hace uso del criterio objetivo de la responsabilidad civil y de la antijuricidad que hay en la falta de acción de esta entidad ante el descontrol de la población canina presente en las calles del distrito.
MIROSLAV MILOVIC "NA CASA DE LÉVINAS"
Authors: Brito Rose
Published: July 2024

O artigo retorna ao texto Na “casa” de Lévinas como um outro modo de reencontrar Miroslav Milovic. A partir de quatro movimentos. O primeiro movimento é um exercício de memória que compartilha o testemunho de Miroslav sobre a apresentação do texto no Congresso de Filosofia em homenagem a Karl-Otto Apel. O segundo movimento indica as repercussões do texto no Brasil pela ruptura do autor com a ética do discurso e pela existência de uma réplica ao texto na Universidade de Brasília. O terceiro movimento justifica as razões de voltar Na “casa” de Lévinas vinte e quatro anos depois. O quarto movimento contextualiza as “casas” (as éticas) referenciadas no texto como pontos de passagem do pensamento nômade de Miroslav Milovic. Ao final, duas hipóteses são comprovadas: a voz do texto é o testemunho do hóspede e a “casa” de Foucault é uma das alternativas na contemporaneidade. A novidade que se pretende partilhar é um diálogo entre dois textos de Miroslav sobre a ética estetizada foucaultiana que aparece Na “casa” de Lévinas ainda como dúvida.

Paisagem e ação antrópica em Santa Fé do Araguaia/TO: subsídios à conservação ambiental
Authors: Sousa Thiago Santos , Lima Helio Alves , Mendes Maurício Ferreira
Published: July 2024

A expansão da agropecuária juntamente com o processo de urbanização são fatores que podem contribuir para a redução de florestas nativas em diversas regiões do Brasil. Assim, o objetivo deste trabalho foi analisar o grau de alteração antrópica da paisagem no município de Santa Fé do Araguaia/Tocantins, no período de 2009 a 2019. Para tanto, realizou-se levantamento bibliográfico em bases oficiais de consulta: SciELO e Portal de Periódico Capes sobre as alterações na paisagem, além da obtenção de forma gratuita das bases cartográficas do Instituto Nacional de Pesquisas Espaciais, na escala de 1:100.000, por meio do seu website. Essas bases foram recortadas, delimitando a área de estudo, utilizando os softwares livres QGis, versão 3.18 e Spring versão 5.4.3. Os dados analisados mostram uma redução da vegetação causada, principalmente, pela pecuária extensiva, que atualmente ocupa 75,65% do município estudado. Os tipos de vegetação Savana Florestada e a Área de Tensão Ecológica, com contato entre Savana e Floresta Ombrófila, tiveram suas áreas reduzidas a 0%, enquanto a Floresta Ombrófila Aberta Submontana teve uma redução de 12,14%. Diante dos resultados, é notável destacar a preocupação com o avanço do desflorestamento, uma vez que as florestas fornecem importantes funções para o equilíbrio dos ecossistemas.
L’impossibile dialogo tra diritto secolare e canonico circa il modello matrimoniale nell’attuale secolarizzazione culturale e le distonie sulla componente dell’amore
Authors: Vecchi Fabio
Published: July 2024

Le attuali soluzioni normative sul regime matrimoniale indicano l’avverarsi di una frattura insanabile tra legislatore civile e canonico, di uno scollamento progressivo per valori. Si tratta di un fenomeno di sistema che, da un lato, nei contenuti, mette in discussione il pensiero giuridico e filosofico ereditato nella civile Europa negli ultimi secoli e, dall’altro, nelle differenti esperienze giuridiche nazionali tra loro comparate, evidenzia le difficoltà di individuare parametri comuni e condivisi sull’impostazione dei possibili effetti civili da attribuire al vincolo canonico.
La divaricazione in atto, tuttavia, denota una crisi culturale profonda del modello matrimoniale, del quale oggi vengono relativizzati i caratteri essenziali, le proprietà non negoziabili subordinate ad un riduttivismo dei valori che si traduce, anche, in un relativismo dei modelli istituzionali.
Si registra, in altri termini, un confuso approccio su ciò che appartiene al naturale e legittimo dominio del diritto e ciò che, come la sfera dei sentimenti umani, a quello si vuole forzatamente ricondurre.
Intangibilità dei caratteri identitari, neutra omologazione al ribasso dei valori antropologici, destrutturazione degli istituti e rifiuto di una lettura giusnatura listica degli stessi, si conformano ad una secolarizzazione che assurge a metodo interpretativo del diritto, con un grave interscambio dei piani politico e giuridico ed i pregiudizievoli esiti che ne conseguono.

Investigation of Surplus (Deficit) Underwriting of Tabarru' Fund on BNI Life Insurance Unit Syariah
Authors: Akib Baso , MYS Muh. Takbir Gawy Al Buny , Salic Jawad Z.
Published: July 2024

This study examines the factors influencing the underwriting surplus (deficit) of tabarru' funds in BNI Life Insurance's sharia unit between June and July 2023. Utilizing a quantitative and descriptive methodology, the research relies on secondary data sourced from BNI Life Insurance's sharia unit financial reports spanning from 2015 to 2022. The sampling technique employed is a saturated sample, encompassing 32 time-series data points extracted from quarterly financial reports. Data collection methods include observation and documentation, with analysis conducted using multiple linear regression analysis through IBM SPSS version 20. The findings indicate that participant contributions have a positive and significant influence on the underwriting surplus (deficit) of tabarru' funds, whereas investment income and claims have a negative and significant impact. Collectively, participant contributions, investment income, and claims significantly affect the underwriting surplus (deficit). The results suggest that enhancing management practices and ensuring the stability of participant contributions, investment income, and claims could improve the underwriting surplus of BNI Life Insurance's sharia unit. The research implies that better company management, coupled with the provision of sharia-compliant products, can increase customer loyalty and public interest, thereby boosting the company's assets.
Perbandingan Penyelesaian Keberatan dan Banding Pajak di Amerika Serikat, Australia dan Indonesia

The research was conducted using normative legal research methods, which were carried out through literature research and literature studies and the approach used in conducting this research was a statutory approach and a conceptual approach, to elements in the tax law system. The research found that the position of the Fiscus in Indonesia which has absolute power in determining the amount of tax and decisions on taxpayer objections according to Law Number 28 of 2007 does not provide fair legal certainty and does not reflect the principle of equal legal position as stipulated in Article 27 paragraph (1) of the 1945 Constitution, because of the risk of tax penalties of 30% to 100% due to defeat in objections and appeals. Unlike the United States, which has three tax courts with FOI principles, and Australia, which provides neutral mediation through the ATO and internal and external settlement channels, Indonesia needs to improve fiscal justice by fulfilling taxpayers' rights such as the rights to information, guidance, hearing, appeal, certainty, privacy, and confidentiality. The principles of fairness, effectiveness, and ease of administration are important to increase tax capacity and ensure taxpayers can carry out their obligations properly.

Dalam suatu proyek pembangunan, perencanaan kegiatan-kegiatan merupakan suatu aspek yang sangat penting untuk menghindari keterlambatan. Untuk itu diperlukan perencanaan dan penjadwalan yang matang agar pengerjaan proyek dapat dilakukan dengan seefisien dan seefektif mungkin. Dalam melakukan perencanaan kegiatan pekerjaan proyek, melakukan percepatan durasi proyek pada perencanaan awal merupakan suatu aspek yang penting juga untuk menghindari keterlambatan. Penelitian ini bertujuan untuk menganalisa estimasi waktu yang dibutuhkan untuk menyeleseaikan proyek pengantian Ball Mill di PT. Freeport Indonesia . Perhitungan penjadawalan proyek dilakukan dengan menggunakan metode Critical Path Method (CPM). Critical Path Method (CPM) merupakan model kegiatan proyek yang digambarkan dalam bentuk jaringan. Kegiatan yang digambarkan sebagai titik pada jaringan dan peristiwa yang menandakan awal atau akhir dari kegiatan digambarkan sebagai busur atau garis antara titik. Dalam penjadwalan diperlukan diagram network untuk menentukan urutan keseluruhan kegiatan. Untuk menyusun diagram network perlu diketahui kegiatan apa yang menjadi predecessor dan successor. Dari hasil perhitungan diperoleh lintasan kritis berada pada aktivitas A – C – D – F – G –H – I – L – M – N – O – P – R – S – T sampai Ya. Sementara itu, pekerjaan lain seperti pekerjaan B – J – K – Q tidak termasuk ke dalam lintasan kritis. Pekerjaan – pekerjaan tersebut tidak termasuk ke dalam lintasan kritis karena dalam perhitungannya memiliki waktu longgar. Dan pada perhitungan waktu menggunakan metode CPM durasi yang di dapatkan adalah 1215 jam yg berarti lebih cepat 29 jam dari jadwal yang dibuat PT X yaitu 1244 jam
The Black Death in the Kingdom of Hungary
Authors: Vadas András
Published: July 2024

Western scholarship has studied the mid-fourteenth-century cataclysm of the Black Death for centuries. In contrast, due to the limited number of contemporary narrative sources, in East Central Europe, until recently historians discussed it only marginally. In the past decades, not independent of the emergence of new methods, such as archaeogenetics and palynology, and novel approaches to studying the Black Death such as climate and environmental history, scholars have increasingly turned to the analysis of the multiple waves of the second plague pandemic in this region. Recent studies have drawn attention to the apparent lack of data on the Black Death in the region while pointing to the potential role of the later waves, such as the pestis secunda and tercia, as well as later medieval and early modern recurrences of the epidemic in the historical demography of Bohemia, Poland, and Hungary. The paper provides an overview of the written evidence of the Black Death in Hungary and publishes in extenso some of the most important documentary evidence of the episodes of the epidemic in the Kingdom of Hungary. It argues that, unlike in the case of Bohemia and Poland, the first wave of the plague can be relatively well pursued by a critical analysis of the written evidence.
Late Medieval Plague Waves in in Eastern Germany and Bohemia
Authors: Bauch Martin , Oertel Christian
Published: July 2024

This paper aims to enhance our knowledge about late-medieval epidemic outbreaks in specific parts of Eastern Central Europe. The first part on modern-day Eastern Germany discusses narrative evidence and its use in the current research on plague history, before bringing in municipal records on testaments and conveyances from Görlitz and Stralsund for the reconstruction of seasonality and mortality rates, as well as funeral inscriptions and pictorial evidence from Erfurt as indirect indicators of plague waves. After a brief discussion of the scarce narrative sources, the second part of the paper concerning Bohemia works with the evidence of the Libri Confirmationum, a source originating from the chancellery of the archbishops of Prague. Every new appointment to a benefice was supposed to be approved by one of the vicars general of the archbishop, and this confirmation usually gives the reason for the vacancy. Expanding on Eduard Maur’s research, death statistics and their frequency are analyzed statistically. The paper provides insight into new evidence for the reconstruction of plague waves, mortality rates and seasonality, and thereby highlights the characteristics of the plague in Eastern Central Europe.
