Among all scientific traditions alive, medical publishing has a good chance to be the oldest. The first fully peer reviewed academic journal, “Medical Essays and Observations” was launched in 1731 by the Royal Society in Edinburgh. Since then, hundreds of medical journals have been published worldwide. Medical publication in Hungary started in 1857 when the famous physician, Markusovszky founded “Orvosi Hetilap”, which has been published since then every week (with short breaks during the world wars). It is now a most prestigious piece in AKJournals’ portfolio, listed in Journal Citation Reports, with a remarkable impact factor.

Abstract

Feeding costs of farmed insects may be reduced by applying alternative nitrogen sources such as urea that can partly substitute true proteins. The aim of this study was to examine the effects of different nitrogen sources on body weight (BW) and survival rate (SR) of the Jamaican field cricket (JFC, Gryllus assimilis), the house cricket (HC, Acheta domesticus), yellow mealworm larvae (YM, Tenebrio molitor) and superworm larvae (SW, Zophobas morio). Crickets were either housed individually or in groups, and larvae were group-housed. Six isonitrogenous feeds composed of 3.52% nitrogen were designed for all four insect species using four independent replicates with micellar casein: urea proportions of 100–0%, 75–25%, 50–50%, 25–75%, 0–100% and 100% extracted soybean meal. All selected insect species were able to utilise urea. However, urea as the only nitrogen source resulted in low final BW. In the HC, the JFC, and the YM on nitrogen basis urea can replace 25% of micellar casein without having any negative effects on BW and SR in comparison to the 100% micellar casein group. In the SW, a 25% urea level did not have a significant effect on final BW, but SR decreased significantly.

Abstract

Bloodstream infections (BSIs) caused by multidrug-resistant bacteria are a critical life-threatening challenge which necessitates the urgency to trigger life-saving treatment in a timely manner. This study aimed to evaluate the time required for rapid detection of carbapenemase-producing Enterobacterales (CPE) directly from blood culture bottles to optimize empirical treatment of BSI, especially in pediatric and infant patients, using a cost-effective method. This study included 419 Gram-negative bacteria, of which Klebsiella pneumoniae and Escherichia coli were the most common CPE causing BSI in pediatric and neonatal patients. Phenotypic and genotypic resistance of the selected isolates (45 K. pneumoniae and 9 E. coli) were determined by VITEK-2 Compact system and PCR, respectively. BACT/ALERT bottles were spiked with isolates. Finally, colorimetric RESIST-BC assay and Vitek-2 compact system were evaluated for the rapid detection of carbapenem-resistant bacteria directly from positive blood culture bottles. All selected isolates were phenotypically resistant to carbapenems. PCR showed that bla NDM and bla OXA-48 were present in all isolates, bla VIM was present in 44.4%, while bla KPC and bla IMP were entirely absent. The RESIST-BC kit showed good agreement with PCR for bla NDM and bla OXA-48, demonstrating high sensitivity and specificity, but not with bla VIM. These findings point out that RESIST-BC assay demonstrated an exceptionally short detection time for CPE, completing all cases within the first hour after the blood culture bottles flagged positive. It is also superior in providing a clue for clinicians on antibiotic combinations that can be administered, depending on the type of β-lactamases detected, promptly and efficiently, with low expenses.

Abstract

Placental abnormalities more frequently occur during pregnancy of somatic cell clones and may lead to pregnancy loss or dystocia. Adventitious placentation, or diffuse semi-placenta, is determined by the development of areas of accessory placentation between the cotyledons due to the abnormal growth of placentomes.

After a full-term pregnancy, a 3-year-old Jersey heifer was referred for dystocia which resulted in the delivery of a dead calf. The cause of dystocia was found to be foetal malposition, while the placenta was physiologically expelled after dystocia resolution.

Grossly, cotyledons appeared reduced in size and number in one placental horn, while the surface of the other horn was covered with microplacentomes. Numerous villous structures without trophoblastic coating were highlighted after histopathology. The dominant sign was an inflammatory reaction. The findings were consistent with inter-cotyledonal placentitis, which led to adventitial placentation.

Diffuse semi-placenta compensates for the inadequate development of placentomes and may occur as a congenital or acquired defect. The outcome depends on its severity: in the worst scenario, pregnancy may not proceed beyond midterm and may be complicated by hydrallantois. In the case under examination, the dimensions of the cotyledons (from 2 to 10 cm) allowed for the natural course of pregnancy.

Abstract

Background and aims

First responders such as firefighters and police officers often experience traumatic events as part of their work. As a result, they are more likely to have mental health issues such as post-traumatic stress disorder, depression, and anxiety compared to the general population. Psychedelic-assisted therapy has emerged as a promising avenue to alleviate these issues, but little is currently known about first responders' interest in, and barriers to, these treatments. Here, we aimed to document first responders' attitudes towards LSD-assisted therapy and previous use of psychoactive drugs.

Methods

We recruited 102 participants through mailing lists of first responders' unions. Respondents were typically male firefighters in western Canada; others were police officers, paramedics, and military personnel across Canada and the United States. They were asked about their attitudes towards LSD- and marijuana-assisted therapies, previous psychiatric diagnoses, psychosocial impairments, and substance use.

Results

Respondents showed higher rates of distress and illicit drug use compared to the general population. Of those who sought professional treatment, a minority reported that the treatment had helped them. The respondents were generally interested in taking part in therapy or research involving LSD or marijuana. The setting (e.g., at home vs. a clinic), therapist presence, and drug dose were commonly reported to influence this participation.

Conclusions

First responders may particularly benefit from psychedelic therapy given their high interest in psychedelic drugs and high rates of treatment-relevant disorders. Better understanding the needs of this population will help inform future clinical trials and psychedelic therapies.

Abstract

Background and aims

Interest in psychedelic research has grown significantly in recent years and the naturally derived substance psilocybin, in combination with therapy, has shown promising results as a treatment for a range of psychiatric conditions. However, the negative effects and risks of psilocybin-assisted treatment are not well-established. The purpose of this study was to investigate the potential negative effects of psilocybin-assisted psychological interventions in both the short and long term.

Method

Semi-structured interviews were conducted with eight psychedelic treatment providers and facilitators. Their content was thematically interpreted.

Results

Three themes of short-term negative effects were identified. They included negative reactions to psilocybin dosing sessions, undesirable processes in the therapeutic relationship, and difficult self-experiences. Four themes of long-term negative effects were identified. They included destabilization of the client, difficulties adapting to life post-treatment, complications in the treatment relationship, and undesirable outcomes.

Conclusions

These results highlight the multifaceted challenges clients may face, emphasizing the need for thorough pre-intervention assessment and post-intervention support. The findings both confirm previous research and highlight new aspects that can contribute to increased safety and be relevant for clinical implementation. Further rigorous research is needed to ensure safety, establish ethical guidelines, and optimize the positive effects of these experimental medicines. Integrating various research approaches and types of measurements will be vital to further our understanding of negative effects of psychedelic-assisted therapy.

A felnőttkori invaginatiók ritkák, klinikai megjelenésük eltér a gyerekkori formáktól. Klinikumuk igen változatos, gyakran atípusos, jellemző, hogy egy klinikai sejtés nyomán gondolni kell az invaginatio lehetőségére. A kiegészítő vizsgálatok közül kiemelkedő szerep jut a computer tomográfiának (CT), ami magas érzékenységgel és fajlagossággal képes kimutatni a béltraktus invaginatióját. Gyógyításuk az esetek legnagyobb részében sebészi, sokszor csak a műtét során lehetséges felismerni a kiváltó okot. Esetismertetésünkben egy rendkívül ritka, felnőttkori, passage-zavart okozó colo-colicus, a bal colonfelet érintő, a colon-flexura lienalis-descendens határra lokalizált invaginatio klinikai jellemzőit, diagnosztikáját és definitív megoldásaként a laparoscoposan asszisztált bal oldali haemicolectomia műtéti megoldását mutatjuk be. Munkánkban összefoglaljuk a felnőttkori invaginatiókra vonatkozó kórélettani fogalmakat, diagnosztikai lehetőségeket, a leggyakoribb kiváltó tényezőket és terápiás lehetőségeket.

Abstract

Background and Aims

Despite increasing public acceptance of the LGBTQ+ community and psychedelic medicines, published accounts of queer psychedelia are limited. Specifically, the queer nature of psychedelics and the parallels between narratives of being queer and of psychedelic experiences, are lacking. This report brings queer experiences of psychedelia out of the metaphorical closet and argues for the development of Queer Affirming models of Psychedelic Assisted Psychotherapy (QA-PAP).

Methods

This knowledge report examines the extant psychedelic literature as it relates to queerness, and positions it against reports of rising anti-2SLGBTQ+ sentiments, and legislation aimed at dismantling civil liberties.

Results

Specifically in Canada, the United States of America, and the United Kingdom, the current socio-political climate fosters increasingly positive attitudes towards psychedelic medicine, while recently won 2SLGBTQ+ civil rights are under attack. The convergence of these trends means the psychedelic community must guard against repetition of mistakes made during the first wave of psychedelic research.

Conclusions

Including queer narratives within psychedelic research is integral to the equitable, safe, effective and accessible implementation of emerging modalities of psychedelic-assisted psychotherapies (PAP), and to ensure that ethical standards protect patients from sexual and gender based violence.

Achalasia cardiae miatt az első oesophago-cardia myotomiát több mint száz évvel ezelőtt Ernst Heller német sebész végezte. Az achalasiás betegek a mai napig ettől a beavatkozástól várják panaszaik megszűnését. Az achalasia napjainkban is chronikus, progresszív betegség, aminek oki kezelését nem ismerjük, a gyógyítására, a panaszok enyhítésére gyógyszeres (calcium csatorna blokkolók stb.), endoscopos (botulinum toxin inj., ballonos tágítás, per oralis endoscopos myotomiát [POEM]) és sebészi (laparoscopos, thoracoscopos myotomia) kezeléseket váltakozó sikerrel alkalmazunk.

A betegség progresszivitása miatt a betegek 5%-ánál a nyelésképtelenségig fokozódó dysphagia, megaoesophagus alakul ki, megoldására műtéti beavatkozás válik szükségessé. A működésképtelen nyelőcső eltávolítása és pótlása kiterjedt, nem elhanyagolható morbiditással és mortalitással járó beavatkozás. Közleményünkben egy 45 éves nőbeteg kórtörténetét, az általunk alkalmazott műtéti beavatkozást ismertetjük. A beteg a műtét óta panaszmentes.
