Effects of corneal collagen crosslinking on confocal microscopic findings and tear indices in patients with progressive keratoconus
Mohammad Ali Zare, Mehdi Mazloumi, Hasan Farajipour, Bagher Hoseini, Mohammad R Fallah, Hadi Z Mahrjerdi, Mohammad-Ali Abtahi, Seyed-Hossein Abtahi
Int J Prev Med
2016, 7:132 (23 December 2016)
DOI
:10.4103/2008-7802.196527
Background:
To evaluate any change in tear indices and confocal microscopic findings after corneal collagen crosslinking (CXL) in patients with progressive keratoconus.
Methods:
Thirty-two consecutive eyes from 23 patients having progressive keratoconus were enrolled in this prospective, interventional cohort study. The standard crosslinking surgery was performed for all patients. Visual, refractive, and topographic evaluations were done before and at 6 months after surgery. Tear function tests and confocal microscopic examination were performed before and at 1 month and 6 months after the procedure.
Results:
There was no significant change in Schirmer-1 test results and tear osmolarity at 1 month and 6 months after CXL. Using confocal microscopy, all eyes showed reduced or absent subepithelial nerve plexus. Differences in basal epithelial cell density, epithelial mean cell area, and keratocyte density in anterior and middle stroma and endothelial cell pleomorphism were all significant at 1 month and 6 months after CXL (
P
< 0.05). No significant change was noted in endothelial cell count and their polymegathism at 6 months follow-up. Significant improvement was noted in uncorrected visual acuity, best corrected visual acuity, flattest corneal meridian (
K
2
), and maximum keratometry in Pentacam (
K
max
) after 6 months of the procedure.
Conclusions
: While CXL would have no effect on tear indices and endothelial cell count, it can cause a significant reduction in subepithelial nerve plexus and significant alterations in epithelial cell density in the anterior and middle stroma.

Prevalence of work-related musculoskeletal symptoms among Iranian workforce and job groups
Alireza Choobineh, Hadi Daneshmandi, Seyed Kazem Saraj Zadeh Fard, Seyed Hamidreza Tabatabaee
Int J Prev Med
2016, 7:130 (15 December 2016)
DOI
:10.4103/2008-7802.195851
Background:
Musculoskeletal disorders (MSDs) are known to cause occupational injuries. This study aimed to collate the existed relevant data and develop a general feature of MSDs problem among Iranian workforce.
Methods:
In this study, we used the raw data related to 8004 employees from 20 Iranian industrial settings distributed throughout the country. In all studies, participants were selected based on simple random sampling method, and the data were collected using demographic characteristics and Nordic MSDs questionnaires.
Results:
The most prevalent MSDs symptoms were reported in the lower back (48.9%), shoulders (45.9%), neck (44.2%), upper back (43.8%), and knees (43.8%). Prevalence rates of MSDs at least in one body region were found to be the highest (90.3%) among health-care workers. Prevalence rates of MSDs symptoms in all body regions were higher among workers with dynamic activities as compared to those of workers with static activities.
Conclusions:
MSDs symptoms were common among the study population. Health-care provider and workers with dynamic activities had the highest rate of MSDs. These results merit attention in planning and implementing ergonomics interventional program in Iranian industrial settings.

Iranian television advertisement and children's food preferences
Masoomeh Hajizadehoghaz, Maryam Amini, Afsoun Abdollahi
Int J Prev Med
2016, 7:128 (15 December 2016)
DOI
:10.4103/2008-7802.195825
Background:
In this study, the nature of food commercials in children's television (TV) was monitored and analyzed; simultaneously, the relationship between recalling TV food commercials and children's interest in them and in the consumption of the same food products was evaluated.
Methods:
A total of 108 h children's programs broadcast on two channels (Two and Amouzesh) of Islamic Republic of Iran Broadcasting (IRIB) media organization were monitored (May 6-12, 2015). Simultaneously, a cross-sectional study using 403 primary schoolchildren (201 boys) in four schools of Shirvan, Northeast of Iran, was executed. The children were prompted to recall all TV commercials broadcast on IRIB. Meanwhile, they were directed to define in the list of recalled TV food commercials those were interested in and the commercials (food products) they actually were willing to consume.
Results:
Regarding the frequency and duration of broadcasting, food commercials ranked fifth and sixth, respectively. Fruit leather and plum paste were the most frequently broadcast food commercials. "High quality" (19%), "good taste" (15%), "novelty," and "message on nutritional composition" (13%) were the most frequent messages used in promoting the sale of food products, respectively. In addition, focus on "high quality/precision in the preparation of the food products" was the most frequently used appeals in TV commercials. There was a significant relationship between recalling TV food commercials and the interest in five out of eight of the commercials (62.5%) (
P
< 0.05). The relationship between recalling TV food commercials and the interest in the consumption of the same food product ("Tomato paste B") was statistically significant for 12.5% of the commercials (
P
< 0.05).
Conclusions:
TV food commercials do not encourage healthy eating. The current study provides convincing evidence for policy-makers and researchers to pay more attention to this area.

Nonprofessional care in chronic critically ill patient: A qualitative study
Leila Mardanian Dehkordi, Monireh Babashahi, Alireza Irajpour
Int J Prev Med
2016, 7:125 (5 December 2016)
DOI
:10.4103/2008-7802.195209
PMID
:28028426
Background:
Decision-making about patients with critical condition transfer from Intensive Care Unit to the general wards be delegated to their families. The aim of the study was explaining the experiences of family caregiver's about care of chronic critically ill patient.
Methods:
This study was conducted with a qualitative content analysis using unstructured interview. Participants were selected purposively from May 2014 to May 2015 and data collection continued until data saturation. Analysis was based on conventional content analysis.
Results:
Participants' experiences classified into three main categories as following: nonprofessional care, enhancing factors of care, and inhibiting factors of care.
Conclusions:
Finding of the current study showed different aspects of care. Care of chronic critically ill patients is a long-term process that affected by different factors. It seems that the exploration of caregivers needs and planning supportive interventions based on their needs improve the quality of care.
