Abstract

One of the biggest challenges of raspberry production in Hungary nowadays is reducing the unfavorable effects of climate change. The maturation phase of main varieties within this region falls in a period of extremely high temperature and atmospheric drought detaining desirable fruit growth. Dedicated plant breeding alone is not enough. An immediate action is required. There has been a need for physical protection against excessive direct radiation. In order to restore, or even save the domestic raspberry production and market, introducing of greenhouse or polytunnel solutions are needed. Experimental plantations of three different raspberry varieties were set in two repetitions: covered and uncovered versions. Each cover has characteristic interaction with light which can generate different environmental conditions and also differences in plant growth and fruit quality. Besides the monitoring of elementary biological indicators, a wide range of sensors (temperature, humidity, solar irradiation) was used to identify differences and to find the optimal tunnel material for maximal plant productivity. Within the framework of the project we also tested a portable spectroradiometer and a snapshot imaging camera to study the practical value of proximal sensing in water- and photosynthetic light use efficiency and vitality mapping.

Abstract

Background and aims

Compulsive sexual behaviour disorder (CSBD) is a medical condition that can impair social and occupational functioning and lead to severe distress. To date, treatment effectiveness studies of CSBD are under-developed; typically, treatment for CSBD is based on guidelines for substance or other behavioural addictions. Mindfulness-based relapse prevention (MBRP) is an evidence-based treatment for substance addiction aimed at, among other things, reducing craving and negative affect—i.e. processes that are implicated in the maintenance of problematic sexual behaviours. However, to our knowledge no prior research has been published evaluating mindfulness-based intervention (MBI) in the treatment of CSBD, except two clinical case reports. Therefore, the aim of the current pilot study was to examine whether MBRP can lead to clinical improvement in CSBD. Methods: Participants were 13 adult males with a diagnosis of CSBD. Before and after the eight-week MBRP intervention, participants completed a booklet of questionnaires including measurements of porn viewing, masturbation and emotional distress. Results: As expected, we found that after MBRP participants spent significantly less time engaging in problematic pornography use and exhibited a decrease in anxiety, depression and obsessive-compulsive (OC) symptoms. Discussion and Conclusions: The findings indicate that MBRP could be beneficial for CSBD individuals. Further clinical effectiveness studies with bigger sample sizes, delayed post-training measurements and randomised control trial design are warranted. In conclusion, MBRP leads to a decrease in time spent watching porn and a decrease in emotional distress in CSBD patients.

Abstract

Excessive consumption of salt causes many diseases, including high blood pressure and cardiovascular system disease. In most countries, salt intake is above the WHO guideline daily intake. In Hungary, the average salt intake is more than double the recommended value. Based on these, significant changes are needed in food technology and recipes. To avoid excessive salt intake Hungary has joined the European Union's community program for salt reduction.

The aim of this study was to compare the salt content in different areas of Mangalitsa ham during the dry salting, and compare the average salt content with the regulations of the Codex Alimentarius Hungaricus. The ham was dry salted with 10% by weight of the meat and placed in a controlled atmosphere storage room. The curing took 21 days. The NaCl uptake was measured with Mohr method. The ham was cut at 3 points Cushion (C), Fore Cushion (FC) and Butt End (BE). The salt content of BE was generally higher than the other two areas (C, FC). The differences can be explained by the difference in the thickness of the pieces of meat and fat. The average salt content of the different areas did not exceed the threshold limit in the Codex Alimentarius Hungaricus. At the beginning of the experiment, the salt content of each meat layer was very different, the absorbed salt was concentrated in the surface layer. Over time, as the ham lost a lot of water and due to the lack of outer salt, a significant increase in salt content began in the meat centrum. By day 80, the salt content of the meat centrum exceeded the salt content of both the fat and the surface layer.

Abstract

The global spread of COVID-19, subsequent stay-at-home requirements, spatial distancing measures, and long-term isolation present additional challenges for persons in recovery. Using an illustrative case from South Africa, we discuss COVID-19 related pornography use through the lens of relapse and substitute addiction. South Africa is the epicenter of the pandemic in Africa, and has issued an alcohol and cigarette ban. Historical examples suggest that responses to forced abstinence may include compliance and abstinence, but also seeking alternatives to the original addiction and substitution. Substitution of alternative activities/objects may provide similar appetitive effects to fill the void of the terminated addictive behavior, temporarily or in the long-term. While substitutes do not necessarily portend a relapse, coupled with isolation and reduced recovery support, they can potentiate relapse to the former or ‘new’ addictive behavior. Addiction professionals should be aware of the potential for such negative impacts during and after the COVID-19 pandemic.

Abstract

Background and aims

Instances of Internet use disorders (IUD) including Internet gaming disorder (IGD) and non-gaming pathological Internet use (ng-PIU) have the extent that they are now a growing mental health issue. Individuals suffering from IUD show a large range of symptoms, high comorbidities and impairments in different areas of life. To date there is a lack of efficient and evidence-based treatment programs for such adolescents. The present registered single-arm trial (ClinicalTrials.gov: NCT03582839) aimed to investigate the long-term effects of a brief manualized cognitive behavioral therapy (CBT) program for adolescents with IUD.

Methods

N = 54 patients (16.7% female), aged 9–19 years (M = 13.48, SD = 1.72) received the CBT group program PROTECT+. IUD symptom severity (primary outcome variable) as well as comorbid symptoms, risk-related variables and potentially protective skills (secondary outcome variables) were assessed at pretest, posttest, as well as 4 and 12 months after admission.

Results

Patients showed a significant reduction in IUD symptom severity at the 12-month follow-up. Effect sizes were medium to large depending on the measure. Beyond the statistical significance, the clinical significance was confirmed using the reliable change index. Secondary outcome variables showed a significant reduction in self-reported depression, social anxiety, performance anxiety and school anxiety as well as in parental-reported general psychopathology.

Discussion and conclusions

The present study shows long-term effects of a manual-based CBT treatment for adolescents suffering from IUD. The results indicate that even a 4-session brief intervention can achieve a medium to large effect over 12 months. Future work is needed to confirm the efficacy within a randomized controlled trial (RCT).

Összefoglaló. Bevezetés: A COVID–19-járvány világszerte hónapokra átalakította a járóbeteg-ellátás működését is. Magyarországon a 2020. március 11-től 2020. június 17-ig fennálló egészségügyi veszélyhelyzeti rendelkezések szabták meg az új kereteket. Célkitűzés: Az első veszélyhelyzeti periódus második felében, 2020. április 22. és 2020. május 5. között mértük fel az epilepsziaellátásban részt vevő orvosok véleményét, hogy milyen mértékben változott a betegek ellátása, és hogyan élték meg a változásokat személyesen. Módszer: Internetes kérdőíves véleményfelmérés történt, a Magyar Epilepszia Liga 2020. április 16–17-re tervezett, de a COVID–19-járvány miatt elhalasztott XV. kongresszusára regisztrált neurológusok között. Kilenc egyszeres vagy többszörös feleletválasztós kérdés és ’szabad kommentár’ mezők álltak rendelkezésre. Eredmények: A megkeresett 116 neurológus közül 33-an válaszoltak (28%), összesen 30 kommentár került rögzítésre. 73%-uk szerint a változások komoly nehézséget okoztak, 15%-uk gondolta, hogy ennek súlyos következményei lesznek. Új betegek fogadása 53%-ban leállt, 25%-ban nagy nehézségekbe ütközött. A gondozott betegek problémáit 49%-ban a távvizit lehetőségeivel élve meg tudták oldani, de 24%-ban ez nem sikerült. A beteg távollétében lebonyolított vizitek 68%-a dokumentált telefonbeszélgetések formájában zajlott. Az orvosok kétharmada veszélyeztetve érezte magát, hogy elkapja a vírust, ebből 40% úgy érezte, nem kap elegendő védelmet, 6% (2 fő) kapta el a fertőzést. Következtetés: A COVID–19-járvány a leginkább az új szakvélemények kiadását érintette, de a gondozási feladatokat sem mindig lehetett megfelelően megoldani. A károkat jelentősen enyhítette az ellátószemélyzet rugalmassága. A telefonvizitek, szükség esetén, az epileptológiában pótolhatják a személyes orvos-beteg találkozásokat. A járvány visszatérésének veszélye miatt a távvizit-alkalmazások technikai fejlesztése és ezek dokumentálási kérdéseinek megoldása fontos. A járványidőszakban a személyzet védelmére nagy figyelmet kell fordítani a fertőződés elkerülése és az orvosok biztonságérzetének fokozása érdekében. Orv Hetil. 2020; 161(46): 1939–1943.

Summary. Introduction: COVID-19 pandemic has transformed the operation of outpatient care worldwide for months. The new framework was set in Hungary by the health emergency regulations that existed from 11. 03. 2020 to 17. 06. 2020. Objective: In the second half of the emergency period, between 22. 04. 2020 and 05. 05. 2020, we surveyed the opinion of physicians involved in epilepsy care about the extent to which patient care had changed and how they experienced the changes in person. Method: An internet questionnaire survey was conducted among neurologists registered for the annual congress of the Hungarian Chapter of the International League Against Epilepsy. Nine single- or multiple-choice questions and ‘free comment’ fields were available. Results: Of 116 neurologists contacted, 33 responded (28%), and a total of 30 comments were recorded. 73% said the changes caused a serious difficulty, 15% thought it would have serious consequences. Reception of new patients was stopped in 53%, and 25% encountered great difficulties. In 49%, the problems of the cared patients could be solved using remote visits, but 24% could not solve them properly. 68% of outpatient visits took the form of documented telephone conversations. Two-thirds of doctors feared catching the virus, 40% of whom felt they were not getting enough protection. 6% caught the infection. Conclusion: The COVID-19 pandemic has mostly affected the issuance of new expert opinions, but care tasks have not always been adequately addressed. The damage was significantly mitigated by the flexibility of the care staff. Telephone visits, if necessary, can replace personal doctor-patient encounters in epileptology. The technical development of remote visit applications and their documentation issues are important. During the pandemic period, great care must be taken to protect staff in order to avoid infection and increase the sense of safety of doctors. Orv Hetil. 2020; 161(46): 1939–1943.
