RESUMO
OBJECTIVE: The COVID-19 pandemic has greatly affected the health sector, especially the speed of healthcare services in hospitals, such as nursing care. This is caused by the low ratio between the number of resources available and the number of cases handled, which leads to suboptimal services. One of the solutions to this problem is to implement a digital (mobile) nursing care information system. Therefore, this study aims to produce a digital (mobile) nursing information system model that is suitable for hospitals. SUBJECTS AND METHODS: The research and development (RnD) method used in this study was carried out in three stages, namely, analysis of information system needs, preparation of the model design, and trial of Mobile Nursing Care Plan Information System (MNCPIS). The design was prepared with the Framework for Application of System Technique (FAST). A total of 148 nurses were selected as respondents using a simple random sampling approach. Data were then collected through interviews, focus group discussions, and questionnaires. Furthermore, MNCPIS was assessed with system requirements analysis using the Performance, Information, Economic, Control/Security, Efficiency, and Service (PIECES) framework. RESULTS: The t-test results indicate that MNCPIS was more effective and appropriate compared to the conventional (manual) types. This was indicated by all the variables measured in the MNCPIS component, including assessment, nursing diagnosis and evaluation, planning, and implementation. Based on these findings, the model can be developed as a nursing care information system to improve the quality assurance of services rendered by nurses. CONCLUSIONS: A mobile plan information system can be implemented in the nursing care department in hospitals to ensure satisfaction and quality assurance for the services provided in hospitals.

OBJECTIVE: Compliance with the 5M health protocols of washing hands, wearing masks, keeping a distance of at least one meter, avoiding crowds, and reducing mobility is the best effort to prevent COVID-19. Adolescents are non-compliant in implementing health protocols during the pandemic. Therefore, this study aimed to investigate the level of compliance with the 5M health protocols. It also examines the relationship between self-efficacy, motivation, and compliance with health protocols. MATERIALS AND METHODS: Data analysis was conducted on a cross-sectional survey of 978 adolescents in Surabaya, Indonesia. Multiple logistic regression was performed to analyze the relationship between the three. Furthermore, adolescent self-efficacy was measured using the General Self Efficacy Scale (GSES), while motivation scale and sociodemographic questionnaire were measured to assess the motivation and characteristics of the respondents. RESULTS: Adolescent self-efficacy in compliance with health protocols is around (92.0%) with an average GSES score of 25.52 + 4.64. The analysis showed that adolescents with high self-efficacy and motivation had a high level of adherence (OR 2.804, 95% CI 2.008, 3.915) and high motivation (OR 2.926, 95% CI 2.087, 4.102), compared to those with low self-efficacy and motivation. CONCLUSIONS: The results suggested that initial identification of self-efficacy and motivation should be addressed to ensure compliance with health protocols to prevent the pandemic.

SETTING: Healthcare workers (HCWs) are at an increased risk of TB worldwide. Individual knowledge and attitudes may influence HCW behaviour, and subsequently, TB risk. Indonesia has the second highest case-load globally. OBJECTIVE: To measure TB knowledge and attitudes among a subsection of HCWs in Yogyakarta, Indonesia, and to explore factors associated with knowledge. DESIGN: A cross-sectional study using an online survey targeting all HCW staff was conducted among HCWs from four pre-selected healthcare facilities in Yogyakarta. Descriptive analysis and a multivariable linear regression were undertaken. RESULTS: Of 792 HCWs, 290 (37%) completed the survey; 64% (n = 185) were medical staff, 33% (n = 95) reported previously being tested for active TB and 8% (n = 24) for latent TB. The mean knowledge score was 7.2/11 (SD 1.5): this was higher among medical staff and those with university education (average score increase: 0.53, 95% CI 0.15 to 0.90; and 0.38, 95% CI 0.01 to 0.74, respectively). Participants agreed that free access to TB screening (93%) and treatment (93%) should be available, and 57% of medical and 77% of non-medical staff would take preventive therapy if eligible. CONCLUSION: Participants had practical understanding of TB; however, gaps were identified in knowledge about TB disease progression and prevention. Prevention programmes were viewed positively. We suggest further TB education and engagement programmes for HCWs.
CONTEXTE: Les travailleurs de la santé (HCW) sont exposés à un risque accru de TB dans le monde entier. Les connaissances et les attitudes individuelles peuvent influencer le comportement des HCW et, par conséquent, le risque de TB. L'Indonésie a le deuxième plus grand nombre de cas dans le monde. OBJECTIF: Mesurer les connaissances et les attitudes à l'égard de la TB parmi un sous-groupe de HCW à Yogyakarta, en Indonésie, et explorer les facteurs associés aux connaissances de la TB. MÉTHODE: Une étude transversale a été menée à l'aide d'un sondage en ligne ciblant tous les HCW de quatre établissements de santé présélectionnés à Yogyakarta. Une analyse descriptive et une régression linéaire multivariable ont été effectuées. RÉSULTATS: Sur 792 HCW, 290 (37%) ont répondu à l'enquête ; 62% (n = 181) étaient des membres du personnel médical, 33% (n = 95) ont déclaré avoir déjà été testés pour la TB active et 8% (n = 24) pour la TB latente. Le score moyen de connaissances était de 7,2/11 (SD 1,5) : il était plus élevé parmi le personnel médical et les personnes ayant une formation universitaire (augmentation moyenne du score : 0,53 ; IC 95% 0,110,93 et 0,38 ; IC 95% 0,010,74, respectivement). Les participants étaient d'accord pour dire que l'accès au dépistage (93%) et au traitement (93%) de la TB devrait être gratuit, et 57% du personnel médical et 77% du personnel non médical suivraient un traitement préventif s'ils étaient éligibles. CONCLUSION: Les participants avaient une compréhension pratique de la TB ; cependant, des lacunes ont été identifiées dans les connaissances sur la progression de la maladie et la prévention de la TB. Les programmes de prévention ont été perçus positivement. Nous suggérons d'autres programmes d'éducation et d'engagement sur la TB pour les HCW.
RESUMO
Protease-activated receptor 1 (PAR1) has been established as a promising target in many diseases, including various cancers. Strong evidence also suggests its role in metastasis. It is proved experimentally that PAR1 can induce numerous cell phenotypes, i.e. proliferation and differentiation. A strong link between PAR1 gene overexpression and high levels of ß-catenin was suggested by a study of the PAR1-Gα(13)-DVL axis in ß-catenin stabilization in cancers. An in vitro study was carried out to analyze PAR1 expression by flow cytometry on CD38+138+ plasma cells obtained from patients either at diagnosis (n: 46) (newly diagnosed multiple myeloma (NDMM)) or at relapse (n: 45) (relapsed/refractory multiple myeloma (RRMM)) and compared with the controls. Our previously synthesized benzoxazole (XT2B) and benzamide (XT5) derivatives were tested with in vitro 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, which revealed significant inhibitory activity on PAR1. We provide docking studies using Autodock Vina of these newly tested compounds to compare with the known PAR1 inhibitors in order to examine the binding mechanisms. In addition, the docking results are validated using HYDE binding assessment and a neural network (NN) scoring function.

BACKGROUND: Zinc deficiency is prevalent in children in developing countries. Supplemental zinc provides therapeutic benefits in diarrhea. OBJECTIVE: We sought to measure the effect of supplemental zinc given with oral rehydration therapy during recovery from acute or persistent diarrhea. DESIGN: We conducted pooled analyses including all available published and unpublished randomized controlled trials of the effects of supplementary oral zinc in children aged <5 y with acute or persistent diarrhea. We used Cox survival regression analysis to evaluate the overall effect of zinc on continuation of diarrhea and possible differential effects in subgroups divided by sex, age, weight-for-height, and initial plasma zinc concentration. Dichotomous outcomes were analyzed by logistic regression. To assess the effects of excluding studies without original data from the pooled analyses, effect-size was estimated for all studies by using random-effects models. RESULTS: Zinc-supplemented children had a 15% lower probability of continuing diarrhea on a given day (95% CI: 5%, 24%) in the acute-diarrhea trials and a 24% lower probability of continuing diarrhea (95% CI: 9%, 37%) and a 42% lower rate of treatment failure or death (95% CI: 10%, 63%) in the persistent-diarrhea trials. In none of the subgroup analyses were the 2 subgroups of each pair significantly different from each other; however, in persistent diarrhea there tended to be a greater effect in subjects aged <12 mo, who were male, or who had wasting or lower baseline plasma zinc concentrations. CONCLUSION: Zinc supplementation reduces the duration and severity of acute and persistent diarrhea.

This is a clinicopathologic study of 150 cases of fibrous histiocytoma of the orbit. The tumors occurred in adults (median age, 43 years). The upper and nasal portions of the orbit were the most common sites of involvement. The most common signs and symptoms were proptosis (60 per cent), mass (46 per cent), and decreased vision (25 per cent). Based on the histopathologic features, the tumors were classified in three groups: benign (94 cases), locally aggressive (39 cases), and malignant (17 cases). The biological behavior correlated well with the duration of symptoms, the size and margins of the mass, and the histologic classification. The rate of recurrence was 31 per cent for the benign tumors, 57 per cent for the locally aggressive tumors, and 64 per cent for the malignant tumors. Follow-up data were obtained for 123 patients, with a mean duration of seven years. The ten-year survival of patients with benign, locally aggressive, and malignant fibrous histiocytoma was 100 per cent, 92 per cent, and 23 per cent, respectively. Nine patients died as a result of the tumor, six from local invasion of adjacent structures and three from metastatic disease. Fibrous histiocytoma is the most common primary mesenchymal orbital tumor of adults. The origin of the neoplasm is probably a primitive mesenchymal cell. Complete surgical excision appears to be the treatment of choice.

One hundred four cases of sebaceous carcinoma that arose from ocular adnexa, with at least five years' follow-up information following diagnosis, were studied to extend the authors' previous observations on various prognostic factors in these tumors. Twenty-three patients died from metastatic disease. Although sebaceous carcinomas elsewhere in the skin are rare, this study establishes that these neoplasms occur much more frequently in the ocular adnexa and have significant morphologic features that identify the more highly lethal carcinomas. The various clinicopathologic features that indicated a bad prognosis were vascular, lymphatic, and orbital invasion; involvement of both upper and lower eyelids; poor differentiation; multicentric origin; duration of symptoms greater than six months; tumor diameter exceeding 10 mm; a highly infiltrative pattern; and pagetoid invasion of the overlying epithelia of the eyelids. In many cases pagetoid change appeared to originate in the underlying sebaceous glands and from there extended to invade the overlying epithelia.

Thirty-one cases of trichilemmoma of the eyelid and eyebrow were studied. All lesions were solitary, small, and asymptomatic. Unlike basal cell carcinoma of the eyelid, trichilemmoma rarely involves the lid margin or the inner canthus. The age range of our patients was from 22 to 88 years old (mean, 56 years). There were 19 men and 12 women. The most frequent clinical diagnoses were verruca vulgaris and cutaneous horn. Typically, the tumor displayed a lobular pattern and was composed mostly of glycogen-rich clear cells. The periphery of the lobules showed palisading of columnar cells and a distinct basement membrane. Histologically, the tumor was frequently misinterpreted as basal cell carcinoma. Review of the literature, including our own series, discloses that the eyelid is the second most common site for trichilemmoma after the nose.

Five patients had juvenile fibrosarcoma of the orbit and eyelid. At initial surgical intervention, the patients ranged in age from newborn to 8 years (mean, 3 years 9 months). Three patients were male and two were female. Proptosis and/or painless swelling of the eyelid were the most common signs and symptoms. Four tumors grew within a few weeks or months, and all five were poorly circumscribed. They were composed of immature, spindle-shaped fibroblastic cells in a classic herringbone pattern or in interlacing fascicles. Hypercellularity and mitotic activity were present in all lesions. The differential diagnosis included rhabdomyosarcoma, fibromatosis, and fibrous histiocytoma. Electron microscopy confirmed the fibroblastic nature of the tumor cells in three cases. Follow-up ranged from one to 32 years (median, seven years). Two of five tumors recurred locally but none metastasized. Apparently surgical excision is the treatment of choice and the tumor has a favorable prognosis.

Six cases of juvenile fibromatosis of the periorbital region and eyelid were studied. The median age of the patients was 8 years (range, 1 to 11 years). A definite propensity for involvement of the infraorbital region and lower eyelid was observed. THREE TUMORS EXHIBITED A PROMINENT LOBULAR PATTERN AND WERE ADHERENT TO THE PERIOSTEUM. The main entities in the differential diagnosis included leiomyoma, neurofibroma, and well-differentiated fibrosarcoma. Two of six tumors recurred locally but did not metastasize. Electron microscopic studies disclosed that the spindle-shaped tumor cells exhibited features of fibroblasts. It appears that conservative treatment (ie, local excision) is adequate.

An 18-year-old woman with malignant teratoid medulloepithelioma had an epibulbar, brown-black mass associated with expulsive hemorrhage and a limboscleral perforation. Histopathologically, a prominent pigmented neuroepithelial component was present and correlated to the black color of the mass. The massive hemorrhage is apparently related to rupture of necrotic and abnormal vascular channels within the angiomatous component of the neoplasm. Other mesenchymal elements included spindle-shaped cells, rhabdomyoblasts, and islands of hyaline cartilage.

Six examples of a distinctive benign retinal tumor, occurring in five children and treated only by enucleation, were studied by light and electron microscopy and tested for S-100 protein, a glial-cell tissue marker. The small placoid, noninvasive lesions were composed entirely of benign-appearing cells with numerous fleurettes. These tumors showed no necrosis or mitotic activity. Ultrastructurally, they were composed predominantly of neuronal cells exhibiting photoreceptor differentiation. Some tumor cells had cytologic features of Müller's fibers and other glial cells that in one lesion stained positively for S-100 protein. In two patients there was a family history of retinoblastoma. All children were alive and well at follow-up examinations conducted three to 14 years after enucleation. To expand our concept of retinoblastoma to include this benign variant, we propose the term "retinocytoma." Although clinically and morphologically distinct from retinoblastoma, retinocytoma should carry the same genetic implication as its malignant counterpart.

Uncontrolled unilateral glaucoma developed in the right eye of a 24-year-old woman. It was caused by the diffuse growth of a nonpigmented nevus of the iris into the anterior chamber angle. Histologically, the nonpigmented nevus cells in the angle were distinguishable from a proliferation of corneal endothelium. Clinically, there was no heterochromia, and a tumor was not suspected as the cause of the glaucoma.

OBJECTIVE: To define the clinicopathologic features of eyelid involvement in Melkersson-Rosenthal syndrome (MRS). METHODS: Four patients with eyelid edema consistent with MRS were evaluated clinically, including diagnostic imaging in 2 patients. Eyelid tissue from these patients was examined by light microscopy and immunohistochemistry. Polymerase chain reaction for herpes simplex virus was performed in 1 case. RESULTS: The 3 men and 1 woman ranged in age from 33 to 74 years. All patients had insidious, painless, nonpitting eyelid edema. Three patients had unilateral edema; one had bilateral, asymmetric involvement. Ipsilateral lip edema was present in 1 case. Computed tomography demonstrated periorbital heterogeneous thickening that corresponded to the microscopic finding of scattered granulomas. All 4 patients demonstrated epithelioid granulomas inside and adjacent to dilated lymphatic vessels. Polymerase chain reaction testing was negative for herpes simplex virus. CONCLUSIONS: Isolated eyelid swelling that mimics thyroid-associated ophthalmopathy may occur in MRS. Computed tomography may be useful in the diagnosis. Biopsy should be performed in all cases of unexplained nonpitting eyelid edema. In the eyelid, MRS is characterized histopathologically by a granulomatous lymphangitis, a finding that seems to be unique to this condition.

Schwannomas (neurilemomas) are benign tumors that arise from Schwann cells in the peripheral nervous system. The most commonly involved nerves that cause neuro-ophthalmic manifestations are cranial nerves V and VIII. In this series of three women, schwannomas presented as intraconal masses that mimicked a cavernous hemangioma, a superior orbital mass transgressing the superior orbital fissure, and an expansive frontal lobe mass with clinical symptoms and signs of increased intracranial pressure. Although all three complained of visual blurring, none of our patients presented with Vth or VIIIth cranial nerve dysfunction. Histopathologic studies demonstrated well-circumscribed, encapsulated spindle-cell lesions with classic Antoni A and B patterns. Histopathologic examination is essential to confirm the diagnosis of a schwannoma that may be otherwise clinically confusing. Direct optic nerve compression, globe indentation with induced hyperopia, or increased intracranial pressure with optic nerve compromise may be responsible for visual symptoms. A multidisciplinary approach is often required because of the size and location of schwannomas.

A 72-year-old woman had epibulbar nodules and a blind eye following trauma in childhood. Histologic examination disclosed a pleomorphic adenocarcinoma of ciliary epithelium with invasion of the epibulbar region, retina, retinal pigment epithelium, and optic nerve. The diagnosis was confirmed by histochemical stains and electron microscopy. The pigmented and nonpigmented neoplastic cells of the ciliary epithelium had a patchy basement membrane around the cell membrane and produced hyaluronic acid in the stroma.

Fourteen cases of rare conjunctival myxoma were studied clinicopathologically. The median age of the eight men and six women was 50 years (range, 18 to 76 years). The tumors appeared as slowly growing, freely movable solitary lesions located primarily in the temporal bulbar conjunctiva. The clinical diagnosis was cyst in many cases. The lesions were removed by simple local excision and did not recur. Histologically, they were hypocellular and were composed of stellate and spindle-shaped cells; some had small intracytoplasmic and intranuclear vacuoles. The stroma contained abundant mucoid material and sparse reticulin and delicate collagen fibers. Scattered mast cells were found in many lesions. Ultrastructurally, the intracytoplasmic vacuoles appeared to be extremely dilated cisternae of rough-surfaced endoplasmic reticulum. Invaginations of the nuclear membrane by the cytoplasm correlated with intranuclear vacuoles seen by light microscopy. Conjunctival myxomas are benign tumors and should be differentiated from other benign and malignant soft-tissue tumors with myxomatous features.

PURPOSE: To describe clinical and/or histopathologic features that could help distinguish endogenous Candida endophthalmitis from endogenous Aspergillus intraocular inflammation and to provide histologic documentation of intraocular spread of these agents. METHODS: Twenty-five patients who underwent enucleation, 13 with morphologic features and/or positive culture for Aspergillus and 12 with histologic evidence and/or positive culture for Candida were included in the study. Clinical information was sought from each case. Patients with AIDS were excluded. The enucleated globes were analyzed to detect location of the fungi, vascular invasion by these agents, and inflammatory response. RESULTS: Candida endophthalmitis was noted in patients with a history of gastrointestinal surgery, hyperalimentation, or diabetes mellitus, whereas aspergillosis was present in patients who had undergone organ transplantation or cardiac surgery. Histopathologically, the vitreous was the primary focus of infection for Candida, whereas subretinal/subretinal pigment epithelium infection was noted in eyes with aspergillosis. Retinal and choroidal vessel wall invasion by fungal elements was noted in cases of aspergillosis but not in cases with candidiasis. Both infectious agents induced suppurative nongranulomatous inflammation. CONCLUSIONS: Unlike Candida endophthalmitis, aspergillosis clinically presents with extensive areas of deep retinitis/choroiditis, and vitreous biopsy may not yield positive results. Histopathologically, it appears that Aspergillus grows preferentially along subretinal pigment epithelium and subretinal space. This intraocular infection is usually associated with a high rate of mortality caused by cerebral and cardiac complications.

We studied a family with a dominantly inherited macular dystrophy resembling Sorsby's pseudoinflammatory dystrophy. Retinal pigment epithelial atrophy and varying degrees of pigment epithelial metaplasia were prominent fundus features in this pedigree. However, findings on electro-oculography were abnormal, unlike previous findings in patients with Sorsby's dystrophy. Histopathologic study of an eye from one patient demonstrated widespread atrophy of the retina, retinal pigment epithelium, and choroid. Although the pseudoinflammatory fundus appearance is common to several macular dystrophies and some eyes with end-stage, age-related macular degeneration, abnormal electro-oculograms and a dominant inheritance pattern distinguish the dystrophy in the present pedigree from other dystrophies and age-related macular degeneration.
