In this interpretative phenomenological analysis study, we explored how persons with mental disorders perceive mental health. Adapting a salutogenic theoretical framework, 12 former inpatients were interviewed. The analysis revealed experiences of mental health as a movement, like walking up and down a staircase. Perceived mental health is expressed both verbally in an everyday language and through body language. Mental health is an aspect of being that is always present and which is nourished by four domains of life: the emotional; physical; social and spiritual domains. Mental health is experienced in everyday life as a sense of energy, and as more or less wellbeing. Exploring persons' meanings of mental health from a subjective perspective can extend the knowledge base that can be used in mental health promotion strategies. 相似文献

This qualitative study explored self-care among 15 Ugandan nurses with reputations for thriving despite having difficult working conditions. The analysis revealed that in the face of potential threats to the nurses' job engagement, they engaged in ‘self-tuning’, a salutogenic process involving introspection, sensibility and reflection leading to coping in one or several of these ways: sharing of experiences, trusting in God's providence, engaging in other enjoyable activities, letting go, adapting based on experiences, guarding against workplace hazards, preserving quiet time or clearly separating work from personal life. This study supports previous research that self-tuning is a learnable skill, critical in helping nurses cope with work-related adversity; this should be emphasized both during nursing training and on the job. 相似文献

Two girls, 5 and 8 years old, with a leiomyosarcoma of the rectosigmoid and ileum, respectively, were treated at Hospital Luis Calvo Mackenna. In each case, a segmental resection with primary anastomosis was done. After the initial surgery, neither girl has received further treatment for the tumor. To date the two patients remain clinically well and apparently tumor free. 相似文献

The distribution of clinical findings in Bechterew's syndrome (ankylosing spondylitis) suggests distinct genetic subgroups 总被引:4,自引:0,他引:4
One hundred and twenty-two consecutive patients hospitalized for ankylosing spondylitis (AS) were reexamined. The frequency of clinical signs and results of tests for associations are presented. Psoriasis was associated with a distal pattern of peripheral arthropathy. Spinal rigidity was predominantly seen in males. Males with phalangeal arthropathy exhibited preserved spinal mobility. This was the case also when HLA B27 positives and patients who did not have psoriasis were considered separately. HLA B27 positive patients in this group had frequently experienced acute anterior uveitis. It seems possible that the disease in such males is the result of combined predisposition to ankylosing spondylitis and psoriatic arthropathy. Hip arthropathy was frequently present in males with spinal rigidity. The associations observed confirm that AS is a heterogenous group of diseases. The term "syndrome" may be suitable for such a heterogenous group, and we prefer the term "Bechterew's syndrome" as the name of this group. When these new findings are added to the previous observations that acute anterior uveitis probably is a clinical, sex-influenced characteristic of HLA B27 positive Bechterew's syndrome, that HLA B27 negative patients with Bechterew's syndrome frequently had psoriasis and were HLA B13 and B17 negative, and that psoriasis was frequent in HLA B27 positive patients as well, we tentatively conclude that different and interacting genetic mechanisms may be involved in the etiology of Bechterew's syndrome. 相似文献

OBJECTIVES: The main aims of the study were to investigate changes in anxiety and depression over time in subjects attending genetic counseling (GC) for hereditary cancer, and secondly, to identify psychological, social, and medical variables associated with the course and outcome of anxiety and depression. METHODS: Of 275 eligible individuals, 221 consented to participate, 214 returned the baseline questionnaire, and were included in a prospective multi-center study. Questionnaires were mailed to the subjects before and after the GC. RESULTS: The mean values for anxiety and depression were quite low at all assessments. Mixed linear analyzes revealed that both anxiety and depression declined over time. Higher age, GC-related self-efficacy, and social support were associated with lower levels of anxiety. More social support, satisfaction with GC, self-rated physical function, and GC-related self-efficacy were associated with lower levels of depression. The effects of social support on both anxiety and depression had a significant interaction with time. CONCLUSION: The results support the buffer theory, which proposes that social support acts as a buffer, protecting people from the potentially pathogenic influence of stressful life events, such as GC. PRACTICE IMPLICATIONS: Subjects with less social support and less GC-related self-efficacy seem to be more vulnerable to anxiety and depression and should be offered extra attention by counselors. 相似文献

The close genetic relationship of human and animal strains of norovirus has raised the possibility of transmission of noroviruses from animals to humans and may explain the emergence of certain norovirus strains. To assess if exposure to bovine noroviruses (NoV) might result in infection in humans, an enzyme immunoassay (EIA) was designed and validated in order to detect antibodies against bovine norovirus. This and two other EIAs were used to test sera from 210 veterinarians and 630 matched population controls for IgG and IgA antibodies to recombinant capsid protein of bovine NoV (rBoV), Norwalk virus (rNV), and Lordsdale virus (rLDV). Of 840 participants, IgG reactivity to rBoV was found in 185 (22%), to rNV in 638 (76%) and to rLDV in 760 (90%). IgG reactivity to rBoV was more common in veterinarians (58/210: 28%) than in controls (127/630: 20% [P = 0.03]). IgA reactivity to rBoV was similar in both veterinarians and controls. Cross-reactivity of IgA and IgG antibodies to rBoV and rNV was seen, but 26% of all specimens positive rBoV antibodies showed high IgG reactivity to rBoV but low reactivity to rNV, suggesting a specific response to bovine antigen. No evidence of overall cross-reactivity of antibodies to rBoV and rLDV was seen. Among veterinarians, youth spent on farm (Odds Ratio [OR] = 1.8) and membership of the bovine practitioners' society (OR = 2.7) were significantly associated with IgG seroreactivity to rBoV. These data indicate that bovine strains of NoV may infect humans though less frequently than human strains. 相似文献

The age‐dependent penetrance of organ manifestations in Marfan syndrome (MFS) is not known. The aims of this follow‐up study were to explore how clinical features change over a 10‐year period in the same Norwegian MFS cohort. In 2003–2004, we investigated 105 adults for all manifestations in the 1996 Ghent nosology. Ten years later, we performed follow‐up investigations of the survivors (n = 48) who consented. Forty‐six fulfilled the revised Ghent criteria. Median age: females 51 years, range 32–80 years; males 45 years, range 30–67 years. New aortic root dilatation was detected in patients up to 70 years. Ascending aortic pathology was diagnosed in 93 versus 72% at baseline. Sixty‐five percent had undergone aortic surgery compared to 39% at baseline. Pulmonary trunk mean diameter had increased significantly compared to baseline. From inclusion to follow‐up, two patients (three eyes) developed ectopia lentis, four developed dural ectasia, four developed scoliosis, three developed incisional or recurrent herniae, and 14 developed hindfoot deformity. No changes were found regarding protrusio acetabuli, spontaneous pneumothorax, or striae atrophicae. The study confirms that knowledge of incidence and progression of organ manifestations throughout life is important for diagnosis, treatment, and follow‐up of patients with verified or suspected MFS. 相似文献
