The effects of information quality of mobile information services on user satisfaction and service acceptance–empirical evidence from Finland

Mobile services are steadily gaining greater foothold in everyday life, both in leisure and business. However, a real mobile services breakthrough, other than voice calls and SMS, has not yet been realized. This study focuses on how different dimensions of information quality affect consumers' satisfaction towards mobile information services and eventually the acceptance of these services. We analyze how these dimensions affect consumer satisfaction in both utilitarian and hedonic use contexts. Results show that all information quality dimensions have a statistically significant positive relationship with user satisfaction. User satisfaction in turn has a positive relationship with the intention to use a service again. Results also indicate that content is more important for users with hedonic goals.
Diaphragm and peripheral muscle thickness on ultrasound: Intra‐rater reliability and variability of a methodology using non‐standard recumbent positions

Background and objective: Reliable measurement of diaphragm and peripheral muscle thickness, using diagnostic ultrasound, has only been validated in the erect posture. However, in many clinical populations, including critically ill patients, the erect posture presents logistic difficulties. This study aimed to validate ultrasound measurement of diaphragm and peripheral muscle thickness in the recumbent position.
Skin adnexal tumours in Kano, Northern Nigeria

Background and Objective: Tumours of skin adnexae are an uncommon group of neoplasms that have not been formally studied in our locality. We undertook this review to document and evaluate the pattern in Kano, northern Nigeria. Materials and Methods: This is a 10-year (2004-13) retrospective study of all skin adnexal tumours diagnosed at the pathology department of Aminu Kano Teaching Hospital (AKTH), Kano. Results: Ninety-two skin adnexal tumours were diagnosed during the study period, and there was no significant gender predilection - males (49%), females (51%). The overwhelming majority were benign (86%), while malignancies comprised just 14%. Patients ranged from 4 to 90 years of age, peaking in the third and fifth decades. The most common histological types were nodular hidradenoma (17.4%), eccrine poroma (9.8%) and pilomatrixoma (9.8%), with sebaceous carcinoma (5.4%) as the most frequent adnexal malignancy. The tumours were most commonly located in the head and neck region (52%), followed by the trunk (25%) and extremities (23%). Conclusion: Skin adnexal tumours are relatively uncommon in Kano affecting predominantly people in the third and fifth decade without a definitive sex predilection. Most of the tumours showed sweat gland differentiation with nodular hidradenoma and sebaceous gland carcinoma being the most common benign and malignant tumours, respectively.
Understanding consumer intention in online shopping: a respecification and validation of the DeLone and McLean model

The increasing popularity of online shopping has led to the emergence of new economic activities. To succeed in the highly competitive e-commerce environment, it is vital to understand consumer intention. Understanding what motivates consumer intention is critical because such intention is key to survival in this fast-paced and hypercompetitive environment. Where prior research has attempted at most a limited adaptation of the information system success model, we propose a comprehensive, empirical model that separates the ‘use’ construct into ‘intention to use’ and ‘actual use’. This makes it possible to test the importance of user intentions in determining their online shopping behaviour. Our results suggest that the consumer's intention to use is quite important, and accurately predicts the usage behaviour of consumers. In contrast, consumer satisfaction has a significant impact on intention to use but no direct causal relation with actual use.
Eficácia e tolerância do nitrofurfurilidene (1) na fase crônica da Moléstia de Chagas

Twenty five patients with chronic Chagas' disease were selected presenting positive serology and high parasitaemia. A group of fifteen partients was treated with Nitrofurfurilidene during 120 days with daily doses of 8-10 mg per kg of body weight. The remaining group of ten individuais received only placebo. Yatrogenic alteration of liver, hematopoiesis or kidney were not obseived during or after treatment. Xenodiagnosis of the experimental 15 patient group was negative at the 60th day of treatment and remained so up to 5 years that the observation lasted. Regarding the serum diagnosis the behaviour was not alike eventhough the experimental group presented lower levels of antibodies after the 12th month of the treatment. The authors discuss the disagreement between the xenodiagnosis and serologie results and offer an hypothesis to justify it. They conclude that Nitrofurfurilidene has some efficiency in the chronic phase of Chagas' disease although less evident than in the acute form.
Social systems that marginalize the psychological and organizational aspects of information technology

Abstract This polemical paper is concerned with identifying the factors which serve to marginalize the psychological and organizational aspects of the development, implementation and use of information technology. Five sets of factors are delineated, those associated with: end-users; suppliers, ‘experts’ and the development process; management and organizations; research and development; and education and understanding. The analysis points to the presence of a complex, mutually reinforcing set of social systems acting to marginalize psychological and organizational concerns, and helps explain the massive difficulties in achieving change. It also reveals that psychological and organizational expertise tends to be supply-pushed rather than demand-pulled into the community. This may help explain why many working in this field fail to practise the user-centred approaches that we preach.
Tissue engineering for pulmonary diseases: Insights from the laboratory

Recent advances in stem cell research and tissue engineering have opened new paradigms for future therapies towards many intractable diseases. Many tissue engineering approaches are also applied in the pulmonary research field. Several materials have been utilized as scaffolds to support lung tissue engineering to recapitulate the three‐dimensional (3D) structure of the lung. Natural products and synthetic polymers are the two major components of the scaffold materials. Decellularization of allogeneic or xenogenic donor lungs is also utilized to obtain biological 3D matrix scaffolds. Decellularized lungs are recellularized with stem or progenitor cells. Cell sources are the key components for tissue engineering. The best cell source for tissue engineering is autologous cells obtained from patients because it does not induce an immunological response after transplantation. However, the stem/progenitor population in adult organs is generally small, and their capacity for proliferation or differentiation is limited. Knowledge about the endogenous stem/progenitor population in lung tissue has been expanded recently. Although the lung is the most challenging organ for tissue engineering because of its complex 3D structure and more than 40 different cell types, several breakthroughs in respiratory research have been made. These results give us a greater understanding of the possibilities and the limitations of tissue engineering for pulmonary diseases.
INVITED REVIEW SERIES: TRANSLATING RESEARCH INTO PRACTICE

Chronic obstructive pulmonary disease (COPD) is an increasing cause of morbidity and mortality worldwide, and it has been strongly correlated to tobacco smoking. While a number of studies have concentrated on smokers only, recent published data demonstrate that at least one fourth of patients with COPD are nonsmokers, and that the burden of COPD in non-smokers is also higher than previously believed. Risk factors of COPD in non-smokers may include genetic factors, long-standing asthma, outdoor air pollution (from traffic and other sources), environmental smoke exposure (ETS), biomass smoke, occupational exposure, diet, recurrent respiratory infection in early childhood, tuberculosis and so on. In Asian region, indoor/ outdoor air pollution and poor socioeconomic status may play important roles in the pathogenesis of nonsmoking-related COPD. The prevalence of COPD among never smokers varies widely across nations. Such a variation may arise from several aspects, including study design, definition of COPD, diagnostic criteria, age and gender distribution of the studied population, local risk factors and socioeconomic status. More investigations and efforts are required to elucidate the involved factors and their shared contributions to non-smoking-related COPD so as to achieve better estimation and reduction of the burden of this neglected entity worldwide.
Urinary tract infection, its causative microorganism and antibiotic susceptibility in Nagaland

Aim: We studied the causative microorganisms and antibiotic susceptibility of urinary tract infections (UTI) for both male and female in Nagaland, North-Eastern India. Materials and Methods: This is a retrospective study done at Christian Institute of Health Sciences and Research, Dimapur, where urinary samples received for culture and sensitivity in the laboratory from January 2012 to June 2013 were included. Organisms were identified by doing standard culture method, and antibiotic sensitivity was done by Kirby-Bauer Disc diffusion method from mid-stream clean catch urine sample. Results: A total of 1789 samples were analyzed in this study, where 502 (28.1%) showed significant growth, 330 (18.4%) showed insignificant growth, and the rest 957 (53.5%) showed no growth. The most commonly isolated bacterium was Escherichia coli both in an outpatient department (31%) and in-patient department (38%) patients followed by Klebsiella pneumonia, Pseudomonas sp. , Enterococcus, Staphylococcus aureus, Candida, and Proteus. Analysis of the samples showed that UTI was more common in females (60%) as compared to males (40%). It was also observed that the samples responded effectively to chloramphenicol (29%), gentamicin (28%), imipenem (26%), and amikacin (21%). High degree of resistance was shown for nalidixic acid, ciprofloxacin, norfloxacin, amoxyclav, and ofloxacin. Conclusion: Antibiotics have been in use for a long period and more often the misuse of antimicrobial drugs has today led to a general rise in the emergence of resistant bacteria. This study may aid health professionals in choosing the appropriate treatment for patients in North-Eastern India.
THE INFLUENCE OF DIFFERENT FAT DIETS ON THE FLUORESCENCE OF THE EYE LENS AND OF SERUM IN ALLOXAN DIABETIC RATS

The connection between some experimental cataracts and the fluorescence of the eye lens in rats has been discussed by Hammar and Brolin (17). A group including galactose, tetanic, roentgen and myleran cataract shows only slight changes in intensity of fluorescence. Another group including naphtalene and diabetes cataract is characterized by a marked increase in fluorescence. An increase is also observed in diabetic humans before opacities are revealed (20). This increase may be caused by a deposition in the lens of fluorescent substances from serum. Metabolic derivatives of naphtalene fluoresce and serum of diabetic rats show an increase in fluorescence when the animals have developed cataract (4). I n alloxan diabetes Ogino et al. (23) found a cataractogenic substance in urine identified as benzoquinone acetic acid. Quinoid substances have fluorescent properties (32) and may be involved. Few data on the nature of fluorescent substances of the lens are available in the literature. A lentoglobulin has been found to be fluorescent (30). Lactoflavin and some dimethyl alloxazines (13) and aneurin (25 ) have been found in the lens. Papers on some less well characterized compounds have also been published recently ( 7 , 11, 14). I t is thus known that several substances contribute to the fluorescence of the lens, but little is known about their behaviour in cataract. In diabetes an increase of fluorescence of the lens is of interest as a sign of disturbed metabolism leading to cataract. Although the chemical bases of this is but poorly understood it is of interest to investigate whether factors which influence the course of diabetes also affect the fluorescence of lens and of serum.
Burn wound septicaemia: analysis of burn infection in burn ward at Dr. S.T.m. Forest Hospital, Haldwani.

The Kumaon region of Uttaranchal in India is a hill state with diversity of people, religion, climatic conditions, geographical distribution, and agricultural practices. This study was conducted in Burn ward, Dr. S.T. M. Forest Hospital and UFHT Medical College, Haldwani, to evaluate the demographic profile, clinical characteristics, and outcome of burn patients in Kumaon region during a period of 2 years. Female patients were in the age group of 18 to 65 years. Housewives were the main victims sustaining burn injuries by cooking on chulha followed by kerosene stoves in hilly areas. Male patients were mainly electric linemen who sustained burn injuries by high tension lines. Major pathogen isolated was Pseudomonas aeruginosa in pus culture reports followed by Methicillinresistant Staphylococcus aureus. The cause of death was mainly burn wound septicemia. The length of stay was 38 days (range, 7–70 days). Our study highlights that flame burn patients were more vulnerable to sepsis. Onset of septicemia was seen to be as early as 3 days and commonly within 2 weeks. A surface wound was the likely source of entry to the blood stream. Pseudomonas organisms were dominant in the etiology. This coincides with the studies performed by Vostrugina et al who diagnosed bacteremia, on an average, on the 15th day after hospitalization and the 16th day after the burn. The causative agent of bacteremia in 71% of cases was methicillinresistant Staphylococcus aureus; 11% of bacteremias were caused by pseudomonas. Altopurlak et al in his study detected that Coagulasenegative staphylococci (63.0%) and Staphylococcus aureus (19.7%) were the most prevalent isolates in admission cultures. Lari reported frequency of Pseudomonas aeruginosa as 73.9% in his study of 2122 patients with burn wound septicemia. Oncul et al found in his study that most common bacteria isolated was Pseudomonas aeruginosa (41.7%). This study throws light on frequent cases of burn injury so very common in Uttarakhand state because of frequent cooking on chulhas due to easy accessibility of firewood and accidents during cooking on kerosene stoves. Facilities for treatment of these cases are not available in Government hospitals. Most of the patients do not survive transportation to the far off centers. There is a need for health education in hilly areas to reduce incidence of burn injury. Because burn injuries are largely preventable, it is important to define clearly, the social, cultural and economic factors, which contribute to burn causation in order to combat them effectively.
Delayed Cooling of an Acute Scald Contact Burn Injury in a Porcine Model: Is it Worthwhile?

The current Australia and New Zealand Burn Association recommended burns first aid treatment is to place the burn under cool running water for 20 minutes. Immediate cooling of a burn wound has been shown to reduce the depth of the injury. Cooling has also been recommended as beneficial for up to 3 hours after the burn. No scientific data currently exist to support this recommendation. The aim of this study was to identify the effect of delayed cooling of an acute scald contact burn wound in a porcine model. Four partial-thickness contact scald burn injuries were induced in 12 piglets each. First aid treatment consisting of cool running water for 20 minutes was instituted randomly to each wound at different time points: immediately and at time delays of 5, 20, and 60 minutes. The group receiving immediate first aid with cool running water for 20 minutes served as the control group. At day 1 and day 9, biopsies were obtained and assessed in a blinded manner. Histologic analysis of burn depth on days 1 and 9 demonstrated no significant difference in the depth of the burn in the various treatment groups in comparison to the control group receiving immediate first aid. No significant differences in the surface areas of each burn were noted between the various treatment groups on day 9. Core body temperature did not fall below 35°C throughout the cooling process. This study provides scientific evidence that in an animal model delayed cooling for up to 60 minutes postacute contact scald burn is still effective compared with immediate cooling at reducing burn depth.
The Effect of Burn Center and Burn Center Volume on the Mortality of Burned Adults—An Analysis of the Data in the National Burn Repository

Regional variations of care, and improved outcomes with larger volumes, have been well described in the medical and surgical literature for a variety of conditions including heart surgery, vascular surgery, and orthopedic surgery. Burn care has not been recently subjected to such an analysis. The National Burn Repository (NBR) contains de-identified patient and burn center data to allow this analysis. The NBR was queried for adult burn patients admitted for an acute thermal burn injury. A multivariable regression analysis to identify risk of death was performed incorporating patient characteristics, de-identified burn center, and burn center volume. Patient characteristics such as age, size of burn, mechanism of burn, inhalation injury, race, and sex determine mortality. There is also a statistically significant difference in death rates when individual, de-identified centers are compared. This difference in care persists even when accounting for burn center volume. Analysis of registries like the NBR, insurance claims databases, and statewide hospital discharge databases may help identify opportunities to improve burn care. According to this analysis of data available in the NBR, burn mortality depends not only on patient characteristics but also where the patient is treated. Mortality does not linearly improve with burn center volume and plateaus with increasing burn center size. The optimal burn center size is a complicated and contentious question. Future discussions about burn center size and density should incorporate not only mortality but also the region’s ability to absorb surges in volume, and the optimal “staffing” ratios for the multidisciplinary aspects of burn care.
CHRONIC DACRYOCYSTITIS: ITS CAUSATION AND TREATMENT

With an auspicious and a drooping eye. —Hamlet, Act 1, Scene 2. The present material supplements the cases already referred to in a paper1on external dacryocystorhinostomy read before the Ophthalmological Society of the United Kingdom in 1932, which dealt with the period from 1929 to 1931. During the years 1932 to 1939 inclusive, 1,073 patients were seen in the ophthalmic clinic of the Royal Infirmary, Edinburgh, under my charge, whose complaint was watering of one or both eyes. This number represents 2.7 per cent of the total number of new patients attending during these years. Of these, 548, or almost exactly 50 per cent, were adults with dacryocystitis. Patients appearing for the first time with acute dacryocystitis were included in the group with watering of the eyes, as they gave that history. Fifty cases of congenital dacryocystitis were collected in two and a half years. This is equal
Personality and technology acceptance: the influence of personality factors on the core constructs of the Technology Acceptance Model

The Technology Acceptance Model (TAM) is one of the most used models in information science. Although several studies investigate the relationship between individual difference variables and TAM, none are conclusive about the relationship between personality and the TAM constructs. The current study seeks to investigate the degree to which users' assessments of the core constructs of TAM are influenced by their personality as measured by a short version of the IPIP Big Five inventory. A web-based survey method was used where users (n = 1004) read a description of a software tool before completing personality and TAM inventories. The results indicate that personality influence behavioural intention (BI) both directly and mediated through the TAM beliefs. Personality can also influence the TAM beliefs without influencing BI. Extraversion has significant, positive relations to BI and this relation is fully mediated by the TAM beliefs. Emotional stability is related to BI, but this relation is not mediated by the TAM beliefs. Openness to experience is significantly and positively related to perceived ease of use, but does not influence BI.
Computed tomography guided fine needle aspiration cytology of pulmonary mass lesions in a tertiary care hospital: A two-year prospective study

Background: Percutaneous or transthoracic fine needle aspiration cytology (FNAC) is a rapidly emerging diagnostic modality to assess the nature of radiologically demonstrated lung lesions. Aims: The present study was conducted to evaluate the usefulness of computed tomography (CT)-guided FNAC in the diagnosis of pulmonary mass lesions. Materials and Methods: The present prospective study was carried out on 74 cases of radiologically diagnosed pulmonary mass lesions involving the periphery of the lung parenchyma with strong clinical suspicion of pulmonary neoplasm. CT-guided transthoracic fine needle aspiration was performed and cytology smears were stained with May-Grόnwald-Giemsa (MGG) stain and conventional Papanicolaou (Pap) stain. Smears were broadly categorized into unsatisfactory, benign, suspicious of malignancy and malignant lesion. The cytological diagnosis was compared with subsequent histopathology report where it was necessary. Results: A total of 74 cases of pulmonary mass lesions were included in the present study, of which 58 were males (78.4%). The mean age of the patients was 51.6 years, but the mean age in case of malignant lesions was 62.5 years. Cough was the most common respiratory symptoms (100%) followed by weight loss (91.9%) and fever (62.2%). Maximum cases of benign lesions were chronic non-specific inflammation (10.8%; 8 cases) followed by tuberculosis (8.1%). Regarding the malignant categories, non-small cell carcinoma, not otherwise specified (NOS) (13.5%; 10 cases) was the most common malignancy followed by adenocarcinoma (10.8%; 8 cases), small cell carcinoma (8.1%; 6 cases) and squamous cell carcinoma (6.7%, 5 cases) respectively. All the 38 cases of malignant lesions were confirmed by histopathology. Out of 10 cases of non-small cell carcinoma, NOS 4 cases were diagnosed histopathologically as poorly differentiated adenocarcinoma, 2 cases as high grade squamous cell carcinoma, 2 cases as large cell carcinoma, 1 case as pleomorphic carcinoma and 1 case as adenosquamous carcinoma. Conclusion: CT guided FNAC is a less expensive, simple, fast and reliable method for diagnosis of pulmonary mass lesions.
