Bully-victims: Prevalence, psychosocial adjustment, and responsiveness to intervention

In this thesis, a unique subgroup involved in the bullying phenomenon, the bully-victims, are identified and examined. Despite the increasing attention on the bully-victims in recent years, their prevalence, psychosocial adjustment, and response to anti-bullying programs has not been clearly determined. Three empirical studies were conducted in this thesis to examine the prevalence of bully-victims. Moreover, in study I, the psychosocial adjustment of bully-victims was compared with that of pure bullies, pure victims, and non-involved students. In study II, different forms of bullying and victimization were compared among pure bullies, pure victims, bully-victims, and non-involved students. In study III, the effectiveness of anti-bullying programs, in particular, the KiVa program, on bully-victims was demonstrated. Overall, bully-victims formed the smallest group comparing with pure bullies, pure victims, and non-involved students, and in general differed from pure bullies rather than pure victims in terms of subjective experience of maladjustment. They employed more verbal, physical, and cyberbullying perpetration, but not indirect bullying; and they were more victimized by verbal, physical, cyber, and indirect bullying. The KiVa anti-bullying program in Finland is effective in reducing the prevalence of bully-victims.

Acetic acid as an intervention strategy to decontaminate beef carcasses in mexican commercial slaughterhouse

Beef can be contaminated during the slaughter process, thus other methods, besides the traditional water washing, must be adopted to preserve meat safety. The objective of this study was to evaluate the effect of 2% acetic acid interventions on the reduction of indicator bacteria on beef carcasses at a commercial slaughterhouse in Mexico. Reduction was measured by the count of mesophilic aerobic bacteria (TPC), total coliform (TC), and fecal coliform (FC) (log CFU/ cm²). Among the different interventions tested, treatments combining acetic acid solution sprayed following carcass water washing had greater microbial reduction level. Acetic acid solution sprayed at low pressure and longer time (10-30 psi/ 60 s) reached higher TPC, TC, and FC reductions than that obtained under high pressure/ shorter time (1,700 psi/ 15 s; P<0.05). Exposure time significantly affected microbial reduction on carcasses. Acetic acid solution sprayed after carcass washing can be successfully used to control sources of indicator bacteria on beef carcasses under commercial conditions.

Malnourished patients on hemodialysis improve after receiving a nutritional intervention

INTRODUCTION: Malnutrition is multifactorial and may be modified by nutritional intervention. We aimed to assess the impact of an intervention on the nutritional status of malnourished hemodialysis patients and their acceptance of a non-industrialized nutritional supplement. METHODS: 18 patients were studied, they were selected from a previous nutritional assessment where nutritional risk was defined as: subjective global assessment > 15 plus one criterion for malnutrition. The following variables were assessed: anthropometric parameters, subjective global assessment, dietary intake, six-minute walking test, quality of life (SF-36), and biochemical tests. Patients were randomized to either Control or Intervention Groups. The Intervention Group received a dietetic supplement during dialysis containing 355 kcal, prepared from simple ingredients. After three months, subjects from the Control Group and other patients also considered at nutritional risk underwent the same intervention. The study groups were compared after three months, and all patients were analyzed before and after the intervention. RESULTS: Fifteen men and three women, aged 56.4 ± 15.6 years-old, nine in each group, were studied. The Intervention Group showed an improvement in the subjective global assessment (p = 0.04). There were differences in role physical and bodily pain domains of SF-36, with improvement in the Intervention Group and worsening in the Control Group (p = 0.034 and p = 0.021). Comparisons before and after intervention for all patients showed improvement in the subjective global assessment (16.18 ± 4.27 versus 14.37 ± 4.20, p = 0.04), and in the six-minute walking test (496.60 ± 132.59 versus 547.80 ± 132.48 m; p = 0.036). The nutritional supplement was well tolerated by all patients, and it did not cause side effects. CONCLUSIONS: The nutritional intervention improved the subjective global assessment and quality of life of hemodialysis patients at short-term. A global intervention by a dietitian produced specific and nonspecific positive effects in the whole group. Nutritional supplementation was feasible, palatable, and had low cost. Its clinical impact and effectiveness need to be further assessed in a larger group of patients at long-term.

Adherence to Treatment in Psychotic Disorders - Development of user-centered mobile health intervention

The aim of this study was to explore adherence to treatment among people with psychotic disorders through the development of user-centered mobile technology (mHealth) intervention. More specifically, this study investigates treatment adherence as well as mHealth intervention and the factors related to its possible usability. The data were collected from 2010 to 2013. First, patients’ and professionals’ perceptions of adherence management and restrictive factors of adherence were described (n = 61). Second, objectives and methods of the intervention were defined based on focus group interviews and previously used methods. Third, views of patients and professionals about barriers and requirements of the intervention were described (n = 61). Fourth, mHealth intervention was evaluated based on a literature review (n = 2) and patients preferences regarding the intervention (n = 562). Adherence management required support in everyday activities, social networks and maintaining a positive outlook. The factors restricting adherence were related to illness, behavior and the environment. The objective of the intervention was to support the intention to follow the treatment guidelines and recommendations with mHealth technology. The barriers and requirements for the use of the mHealth were related to technology, organizational issues and the users themselves. During the course of the intervention, 33 (6%) out of 562 participants wanted to edit the content, timing or amount of the mHealth tool, and 23 (4%) quit the intervention or study before its conclusion. According to the review, mHealth interventions were ineffective in promoting adherence. Prior to the intervention, participants perceived that adherence could be supported, and the use of mHealth as a part of treatment was seen as an acceptable and efficient method for doing so. In conclusion, the use of mHealth may be feasible among people with psychotic disorders. However, clear evidence for its effectiveness in regards to adherence is still currently inconclusive.

Pissakoulu lasten toiminnallisen kastelun hoidossa: Intervention vaikuttavuuden arviointi kastelun määrän ja lasten kokemuksien avulla

Kastelu on merkittävästi lapsen arkielämää haittaava kiusallinen oire. Koulun aloittavista perusterveistä lapsista 10 – 25 % kastelee viikoittain joko päivällä ja/tai yöllä. Keskeistä kastelevan lapsen hoidossa on kastelua vähentävien ja virtsarakon hallintaa lisäävien tapa-asioiden ohjaus ja uusien toimintamallien vakiinnuttaminen lapsen arkeen. International Children’s Continence Societyn (ICCS) suositusten mukaan arjen tapa-asioiden ohjaukseen perustuvan uroterapian tulisi olla kastelevan lapsen ensisijainen hoitomuoto. Tutkimuksen tarkoituksena oli arvioida pissakoulu-intervention vaikuttavuutta kastelun hoidossa sekä kuvata lasten kokemuksia pissakoulusta. Tutkimusasetelmassa käytettiin toisiaan täydentävinä sekä kvantatiivisia että kvalitatiivisia aineistonkeruumenetelmiä. Kuusikymmentäyhdeksän hoitoresistentiksi kastelijaksi luokiteltua 6-12-vuotiasta lasta osallistui polikliiniseen pissakouluun 4-6 lapsen ryhmissä kahtena erillisenä päivänä kahden kuukauden välein. Otoskooksi määriteltiin voima-analyysin perusteella 52. Ohjauksen sisältö perustui ICCS:n suosituksiin ja toteutuksessa painotettiin lapsilähtöisyyttä sekä yhdessä tekemistä ja keskustelua. Kvantitatiivisen osan aineistonkeruumenetelmänä käytettiin viikon WC-päiväkirjaa. Kastelun määrän muutoksia mitattiin ennen ja jälkeen molempien pissakoulupäivien ja tulokset analysoitiin SPSS tilasto-ohjelmalla. Kvalitatiivinen aineisto kerättiin pissakoulun toisen päivän päätteeksi haastattelemalla viisi ensimmäistä pissakouluryhmää, jonka jälkeen aineiston todettiin saturoituneen. Ryhmäkeskustelut analysoitiin aineistolähtöisellä sisällönanalyysillä. Tutkimukseen osallistuneista 69 lapsesta 58:lta saatiin tiedot kaikilta neljältä mittauskerralta. Lapset olivat iältään keskimäärin 8,3 vuotiaita, 34 oli tyttöä ja 24 poikaa. Verrattaessa ensimmäisen ja viimeisen mittauksen keskiarvojen välisiä eroja kuivat päivät (3,5 vrt. 5,3, p<0.001) ja kuivat yöt (2,4 vrt. 3,9, p<0.001) lisääntyivät tilastollisesti merkitsevästi. Päiväkastelun osalta 24/40 (60 %) ja yökastelun osalta 23/46 (50 %) lapsella kastelu väheni ≥50 %. Kuivaksi tuli 13/58 (22 %) lasta. Ryhmähaastatteluihin osallistui 19 lasta (12 tyttöä ja 7 poikaa, keski-ikä 8,9 vuotta). Lapset kokivat kastelun monella tapaa arkea haittaavaksi noloksi pulmaksi. Pissakoulu auttoi heitä tulemaan pissarakon pomoksi, jolloin pulmasta tuli hallittava tai siitä pääsi kokonaan eroon. Erityisen tärkeää lapsille oli tavata toisia kastelevia lapsia ja jakaa kokemuksia heidän kanssaan sekä oppia tekemällä lapsilähtöisin menetelmin. Pissakoulu on lapsilähtöinen ja vaikuttava hoitotyön interventio, joka arjen tapa-asioiden muutoksilla auttaa lapsia saavuttamaan paremman virtsarakon hallinnan ja vähentämään kastelua tarjoten myös arvokasta vertaistukea.
