Purpose: There are ongoing public initiatives to help substance abusers by involving peer recovery coaches (PRCs) in the field of substance abuse worldwide. This study examines the contents and delivery methods of PRC intervention programs and their effects from the participants' standpoint. Methods: An integrative literature search was conducted in seven electronic databases using English and Korean search terms. Two researchers independently reviewed the extracted papers and rated their quality based on predetermined inclusion and exclusion criteria, resulting in the selection of nine papers. Results: Research on PRC participation in substance abuse treatment were predominantly US-based, and all articles derived were quantitative studies. The main roles of PRCs included liaising between treatment and community resources, assisting with stress management and coping skills, counseling and case management, and recovery and recurrence prevention education. In addition, the PRC-delivered intervention was tested with various outcome variables. It reduced participants' substance use and enhanced their treatment adherence rates, self-efficacy, quality of life, and stress control. Conclusions This study confirmed the need to extend existing studies by testing the effects of PRCdelivered intervention through multidisciplinary efforts in more regions and establishing PRCs' role definition and concretization. The results of this study will serve as significant basic data in developing and applying for nursing intervention programs with PRCs in clinical and community nursing settings in the future.

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.

Malignant small cell tumor(MSCT) of the thoracopulmonary region(Askin tumor) is extremely rare and is seen predominantly in children and adolescents. This tumor represents a distinct clinicopathologic entity of neuroectodertnal origin, arising from the soft tissues of the chest wall or peripheral lung. This tumor tends to recur locally, but does not seem to disseminate widely. The overall survival is poor. Recently, we experienced a case of the MSCT of the thoracopulmonary region of a 12-year-old female. She was admitted because of a chest wall mass on radiographic examination, and a complaint of intermittent chest pain. Grossly, the mass was lobulated, round and had a solid appearance with focal necrosis and hemorrhage on the cut surface. Histologically, small round to oval cells were arranged in compact sheets, nests and lobular patterns with intervening fibrovascular stroma. Ultrastructurally, the presence of loose-fitting membrane-bound neurosecretory granules was noted.

PURPOSE: The purpose of this study is to survey health requirements of middle-aged women and their families and to provide guidelines for developing nursing interventions by describing the process of family health maintenance experienced by middle-aged women and its conceptual system. METHODS: To get saturated data, each of four researchers conducted two or three times of in-depth interview with eight middle-aged women aged between 40-64 years old and living in Seoul and Chuncheon from the 10th to the 30th of October 2004 and each interview was continued one or two hours. The Grounded theory adopted by Strauss & Corbin (1998) is a substantive theory that can explain the experiencing process of middle-aged women. RESULTS: We found that the casual condition of family health maintaining by middle-aged women was "confidence of health belief", and "pouring by body moving" was found to be its phenomenon. A textual condition that might respond to the phenomenon was "fatal roles acceptance", and intervening conditions that promote their family health were "retracing" and "gathering health information". These intervening conditions impacted middle-aged women's confidence in family health and led them to take actions/interactions such as "being a model of health", "adapting to circumstances", "do-it-myself", "taking-care" "harmonious mind" and "the pursuit of cleanness". These actions/interactions produced results such as "being stronger", "being unmanageable" and "being fruitful". CONCLUSIONS: Health confidence and practical health behaviors were observed in the process that the middle-aged female participants experienced unmanageable circumstances but they accepted their roles and responsibilities and recognized that they must be get stronger. The behaviors of health-together-with were divided into enthusiastic type, adaptation type and self-sacrificing type. Therefore middle-aged woman with the understanding of family health maintaining process as well as the theoretical system and practical principals needs to implement the intervention in acceptable level of family health process of preventing psychological and physical problems.

The author examined the number of AgNORs and PCNA labeling indices by histochemical and immunohistochemical studies in 20 cases of renal cell carcinoma, composed of 5 cases according to the nuclear grades. The results obtained are summarized as follows; 1) Mean number of AgNORs according to the nuclear grades of renal cell carcinoma were 1.38+/-0.40 (mean+/-standard deviation) for Grade I, 2.53+/-0.33 for Grade II, 5.43+/-0.66 for Grade III, and 7.88+/-0.72 for Grade IV. The mean numbers of AgNORs according to the nuclear grades were significantly increased(p=0.0005). 2) PCNA labeling indices (positive nuclear ratio) according to the nuclear grades of renal cell carcinoma were 5.90+/-2.36 for Grade I, 19.30+/-6.71 for Grade II, 45.73+/-8.62 for Grade III, and 61.83+/-6.34 for Grade IV. Also, the PCNA labeling indices according to the nuclear grades were significantly increased(p=0.0008). 3) The mean numbers of AgNORs directly correlated with the PCNA labeling indices (r=0.9861, p<0.001). On the basis of the above results, it was considered that the numbers of AgNORs and PCNA labeling indices as markers of proliferative activity of tumor cells correlate well with the nuclear grades of renal cell carcinoma.

35 neurogenic tumors of the thorax were analyzed with plain film and CT scan. Radiological analysis emphasizedshape, location calcification, bone change, pleural change in plain film and calcification, cystic change, bonechange, pleural change, presence of contrast enhancement in CT scan. The results were as follows; 1. Age may bethe most important clinical factor for differential diagnosis. 2. Plain film findings(35 cases); 1) The mostcommon shape in the ganglion series tumor (ganglioneuroma, ganglioneuroblastoma, neuroblastoma), was elongation(80%) and these tumors generally had tapered borders(50%). In contrast with those of the genglion series, nervesheath tumors(schwannoma, neurofibroma, malignant Schwannoma) showed a definite tendency to be roudn (95%) and thesulcus effect was more frequetnly seen(67.5%). Most of the masses were smooth. The lobulated masses were commonlymalignant ganglion series tumors. 2) Though overall incidence of calcification was low(8.6%), it was observed morefrequently in ganglion series tumors(20%). 3) Associated bony abnormality were generally observed in large tumorsabove 5cm in long axis, especially in neuroblastoma and ganglioneuroblastoma. 4) Tumors showed pleural effusionwere all malignant. 3. CT findings (17 cases); 1) The overall incidence of cystic change of the mass was 23.6%. Itwas most common in Schwannoma(60%). 2) The contrast enhancement was noted in 64.7%. It's degree was variable andshowed no predilection to any specific tumors. 3) The incidence of calcification, associated bony abnormality andpleural effusion were similiar to plain film. Confident specific diagnosis can be made in most of the neurogenictumors of the thorax by shape of the mass in plain film and internal architecture in CT combined with patient'sage as clinical information.

Purpose: Various intervention strategies are needed to reduce the suicide rate among late adolescents. Therefore, we aimed to investigate the factors that can help overcome suicidal tendencies in late adolescents from the perspective of case managers. Methods: This qualitative study explored the reinforcing factors that can help overcome suicidal behaviors in late adolescents, by conducting focus group interviews with case managers from the local community. Interviews with 10 case managers were recorded and transcribed, and the data were analyzed using the content analysis method. Results: The main theme of this study was “a step in a new direction”. Three categories were derived: “inner changes”, “another possibility opened up by the interest of significant others”, and “connecting with community resources to help overcome”. Each category had subcategories that influenced the intention and course of action of behaviors to overcome the suicide crises. Conclusion Our findings, from the exploration of the experiences of case managers, provide an in-depth understanding of the reinforcing factors for overcoming suicide among late adolescents. They provide useful preliminary data for the development of effective suicide prevention programs for the adolescents.

Background: Remdesivir is a US Food and Drug Administration-approved drug for coronavirus disease 2019 (COVID-19). Clinical trials were conducted under strictly controlled situations for a selected population, and their reported adverse events may not fully represent conditions in real-world patients. We aimed to estimate the incidence of adverse drug events (ADEs) associated with remdesivir in hospitalized patients with COVID-19, including vulnerable subpopulations, such as those with impaired renal or hepatic function and pregnant women. Methods: This retrospective observational study included hospitalized patients with confirmed COVID-19 treated with remdesivir between January and December 2021 at ten hospitals. ADEs and severe ADEs (Common Toxicity Criteria for Adverse Events grade ≥ 3) were operationally defined and analyzed through laboratory investigations. The incidence of ADEs was compared with that of each matched control in subpopulations with renal or hepatic impairment and pregnant women. Results: Among 2,140 patients, 1,416 (66.2%) and 295 (13.8%) experienced at least one ADE and severe ADE, respectively. The most frequent ADE was 'hepatic injury' (42.9%), followed by anemia (27.6%). The most common severe ADEs were 'hypokalemia' (5.3%), 'hepatic injury' (2.9%), and 'anemia' (3.6%). There was no significant difference in the incidence of ADEs in patients relative to their respective matched-control groups, including those with renal impairment (80.0% vs. control 71.8%, P = 0.063), hepatic impairment (70.4% vs. control 75.0%, P = 0.623) and pregnant women (78.6% vs. control 63.7%, P = 0.067). However, severe ADE incidence was significantly higher in patients with renal impairment (40.8% vs. 16.0%, P < 0.001). The most common severe ADEs in those were 'anemia' (15.3%), 'hypokalemia' (10.5%), and 'thrombocytopenia' (8.9%). There was no statistically significant difference in the incidence of severe ADEs in patients with hepatic impairment or in pregnancy (P = 0.230; P = 0.085). Conclusion A significant proportion of patients with COVID-19 treated with remdesivir experienced ADEs and severe ADEs. Given the high incidence of severe ADEs, caution is required in patients with renal impairment. Further studies are needed to investigate ADEs in pregnant women and patients with hepatic impairment.

Uterine metastasis from stomach carcinoma occurred in a patient who five years previously had undergonegastrectomy for gastric adenocarcinoma. CT scans showed an ill-defined lobulated low density mass in the center ofthe uterus. T1-weighted MRI imaging showed that the lesion was indistinct from the myometrium; on T2-weightedimaging it showed increased signal intensity and had infiltrated the myometrium. After Gd-DTPA administration, thelesion showed very little enhancement.

An attenuated classical swine fever virus (CSFV), Suri strain, is a va.iant derived from a vaccine virus, LOM strain. This study was performed to elucidate the molecular biologcal properties of CSFV Suri strain, and to obtain the basic data for molecular epidemiological approaches for the disease. The truncated form of gp55 gene without the C-terminal transmembrane domain, in size of 1,023bp, was amplified by RT-PCR and sequenced by dye terminator cyclic sequencing method, and inserted into BamHI site of pAcGP67B baculovirus vector, establishing a cloned pAcHEG plasmid. By the nucleotide sequences determined, 341 amino acid sequences were predicted. As compared the nucleotide and amino acid sequences of gp55 of Suri with the various CSFV, Suri strain showed the high homology over 99.1% with ALD and LOM strains, but comparably the lower homology with Alfort and Brescia. In comparison of amino acid sequence in variable domain of gp55 protein, the similar tendency of homology was observed. In hydrophobicity analysis, all of four CSFV strains revealed the analogous patterns of hydrophobicity. The numbers and locations of N-glycosylation site and cysteine residues in gp55 were analyzed, those of Suri strain being coincident with ALD and LOM strains. The results suggest that gp55 in Suri strain has the high similarity to those in ALD and LOM strains in terms of the nucleotide and amino acid sequences and the functional properties of gp55 protein..
