Nursing students' experiences of the implementation of family-centered care protocol in pediatrics
Background and Objective: Clinical education is considered one of the most important parts of nursing
education. There is little interest in family-centered care in education of students. This study was conducted
to investigate the nursing students' experiences in family-centered care in 2013.
Materials and Methods: Participants were 8 nursing students in their sixth semester who were selected
purposely. The principles and concepts of family-centered care and teaching process based on these
principles were developed and implemented. The students' experiences with teaching family-centered care
were examined. Interviews with eight nursing students were saturated with these experiences and were
analyzed by qualitative content analysis.
Results: Based on the analysis of data, three main categories were obtained. The main category of students'
eagerness consisted of three subcategories including novelty and attractiveness of family centered care, close
connection between theory and practice, and reducing stress. The main category of the barriers to implement
family-centered care consisted of the following four subcategories: staff shortage, lack of time, space
shortage and personnel unawareness of the concept of family-centered care. The main category of the need to
implement family-centered care consisted of three subcategories including the necessity for space
replacement, personnel training and paying attention to the parents' role.
Conclusion: Family-centered care improves family and infant health and increases students' satisfaction.
Also family-centered care is a priority for the Ministry of Health. It is recommended to implement the
family-centered care course in undergraduate education
Modeling Compressible Non-Newtonian Chicken Flow
This paper addresses a few modeling issues relevant for the basic theoretical understanding of the meat flow behavior in simple geometries. We model the meat mixture as a non-Newtonian compressible fluid. Focusing on conceptually easy-to-follow cases like flow in thin molds, or steady incompressible or compressible flow in straight pipes we derive explicit expressions for the velocity and pressure profiles. For the thin moldcase, we formulate a one-dimensional free-boundary problem able to capture the a priori unknown position of the moving meat-air interface. Special attention is payed on the derivation of the free boundary conditions
Developing the Principles of Parental Mental Health in the Neonatal Intensive Care Unit (NICU)
Background: Hospitalization of infants in the neonatal intensive care unit (NICU) may disrupt the proper interaction
with infants and lead to anxiety and depression, while adversely affecting the role of families. Therefore, it is necessary
for healthcare teams to be familiar with the principles of parental mental health in the NICU. The present study aimed
to codify the principles of parental mental health in the NICU.
Methods: This study was conducted with a triangulation methodology in two steps. In the first step, the principles of
mental health care for parents in the NICU were compiled and translated. In the second step, the principles were edited
using the Delphi method based on the opinion of experts (physicians, faculty members, and health policymakers). Final
principles of parental mental health in the NICU were codified.
Results: In total, four general principles of holistic care, relationship with parents in the NICU, special care for
establishing communication with families in the NICU, and principles of infants and family care were obtained.
Conclusion: Since healthcare teams may not be familiar with the principles of parental mental health in the NICU, the
results of the present study could lay the groundwork for promoting the knowledge of healthcare team members in
interaction with parents
The core of pomegranate (Punica granatum) seed kernel meal effects of growth parameters of rainbow trout (Oncorhynchus mykiss)
This study was aimed to investigate the effects of pomegranate (Punica granatum) seed kernel meal (pskm) as a supplement in the diet of rainbow trout (Oncorhynchus mykiss), The experiment was carried out in growth in a period of 90 days since the 12/11/2014 until the 12/03/2015 in Abzi Eksir Koesar complex , situated in south east of Tehran. 600 fingerlings with average weight of 6.74 gram and average length of 5.50 centimeter were divided to five treatments, The control group was without any pskm, and the other groups with added 1, 2, 3 and 4 percent pskm Respectively. For greater certainty each treatments had three replicates. Result indicated that pskm caused highest increased growth parameters in treatment 3 with 3 percent pskm, with other treatments and groups. growth parameters including weight with maximum of 47.74 gram, length were 15.03 centimeter, weight gain with maximum of 41.15 gram, length increase with the maximum of 9.71 centimeter, Weight gain percentage with maximum amount of 572.1, specific growth rate with 0.45 and specific length rate with 0.1 mm. All growth parameters with the best value was seen in treatments 3. This result is due to the presence of high levels of appetite stimulants such as polyphenols of pskm (p<0.05). Result also indicated that the level of pskm in treatment 4, did not cause enough different with the control group, mainly because of higher amount of tannin in their diet
Living with cancer challenges: a qualitative analysis of cancer patients’ perceptions in Iran
Aim
Cancer patients are confronted with different challenges. The purpose of current study was to explore Iranian cancer patients’ perceptions of these challenges.
Subjects and methods
The study took a qualitative approach. Semi-structured interviews were held with 26 cancer patients in four university hospitals in Iran. Transcripts of the interviews underwent conventional content analysis, and categories emerged.
Results
The findings came under two major categories: psychological challenges and socio-cultural challenges. Psychological challenges had two subcategories: repressed wishes, and negative feelings. Socio-cultural challenges also had two subcategories: deteriorated relationships and work distress.
Conclusion
Findings of the current study have potential to identify psychosocial challenges of cancer patients. These findings propose that psychological support is essential for them. Our results recommend that healthcare providers should work to remain sensitive to cancer patients’ challenges. There is a need for culture-based caring programs that are responsive to these patients
Amodiaquine-induced toxicity in isolated rat hepatocytes and the cytoprotective effects of taurine and/or N-acetyl cysteine
Amodiaquine is an antimalarial drug used in the prophylaxis and treatment of this disease. However,
hepatotoxicity as a life-threatening adverse effect is associated with its clinical use. We evaluated
amodiaquine-induced toxicity in isolated rat hepatocytes as an in vitro model for studying drug-induced
hepatotoxicity. This study attempts to investigate the protective effects of taurine and N-acetyl cysteine
against the cytotoxicity induced by amodiaquine. Hepatocytes were prepared by the method of collagenase
enzyme perfusion via portal vein. This technique is based on liver perfusion with collagenase after removal
of calcium ion (Ca2+) with a chelator (ethylene glycol tetraacetic acid (EGTA) 0.5 mM). Cells were treated
with different concentrations of amodiaquine, taurine and N-acetyl cysteine. Cell death, protein
carbonylation, reactive oxygen species formation, lipid peroxidation, and mitochondrial depolarization were
assessed as toxicity markers. Amodiaquine cytotoxic mechanism involved protein carbonylation as well as
reactive oxygen species formation and lipid peroxidation. In addition, mitochondria seem to be a target for
amodiaquine to induce cellular damage. Administration of taurine (200 µM) and/or N-acetyl cysteine (200
µM) reduced oxidative stress, lipid peroxidation and protein carbonylation caused by amodiaquine.
Furthermore, amodiaquine-induced mitochondrial injury was significantly mitigated by taurine and/or Nacetyl
cysteine. In glutathione-depleted cells, only N-acetyl cysteine protected hepatocytes against
amodiaquine, and taurine showed no protective properties in this situation. Taurine and N-acetyl cysteine
protect hepatocytes against amodiaquine probably via their antioxidant properties and counteracting
oxidative stress
Competitive contagion in networks
We develop a game-theoretic framework for the study of competition between firms who have budgets to “seed” the initial adoption of their products by consumers located in a social network. We identify a general property of the adoption dynamics — namely, decreasing returns to local adoption — for which the inefficiency of resource use at equilibrium (the Price of Anarchy) is uniformly bounded above, across all networks. We also show that if this property is violated, even the Price of Stability can be unbounded, thus yielding sharp threshold behavior for a broad class of dynamics. We provide similar results for a new notion, the Budget Multiplier, that measures the extent to which the imbalances in player budgets can be amplified at equilibrium
The constituents of essential oils of Ferulago angulata (Schlecht.) Boiss at two different habitats, Nevakoh and Shahoo, Zagross Mountain, western Iran
Abstract – Ferulago angulata (Apiaceae), a medicinal plant of western Asia, contains essential oils that are
used as a food preservative. This study examined and compared the composition of leaf oil with seed oil and
of the oils from two different habitats (one from Nevakov and the other from Shahoo). The oil yield from seed
was 5-fold that from leaves (3.2%/100g compared to 0.63%/100g). Cis-ocimene was the major constituent of
the seed oil from both regions (64.8% and 76.11%) and a prominent constituent (>20% of the total oil) of the
leaf oils of both habitats. α-Pinene was the next main component (7-27%) of all 4 oils. Seed oils, with one
major component (cis-ocimene), differed from the leaf oils, which were composed mostly of 3 components
(α-pinene, cis-ocimene, & germacrene D). Distinctions between the oils of the two habitats were less marked
than the leaf-oil/seed-oil differences; the cis-ocimene content was higher and α-pinene was less in both seedand
leaf-oils of the Shahoo habitats than the Nevakoh ecotype; trans-verbenol was absent from the Shahoo
leaves, but reached a content of 5.8% in Nevahoh leaf-oil. Further distinctions were found in the
content/presence/absence of 20-30 minor components of the oils
An Exploration of the Viewpoints of Parents and Nurses on Care Provision in Neonatal Intensive Care Units
Background: Infants are regarded as a vulnerable group in need of nursing care, particularly during NICU admission. Parents of these infants often experience emotional, psychological and physical upheavals. Therefore, nurses can be of great help to the parents and facilitate a healthy transition from this period. Improper communication with parents, who seek information on their infant's condition, intensifies their stress, fear and misunderstanding. In fact, inadequate communication with healthcare providers and lack of family support are major issues for the parents of NICU-admitted infants. Methods: In this qualitative study, via content analysis, we objectively selected and collected data from parents, physicians and nurses, residing in Isfahan, Iran in 2012. Data saturation was reached after conducting 25 in-depth, semi-structured interviews. Results: Based on the findings, five major categories were extracted: 1) care provision in NICUs; 2) diagnostic difficulties; 3) NICU admission process; 4) challenges of hospitalization; and 5) maintenance of infant viability. Conclusion: Nurses' proper response to parents' questions about the infant's condition reduced stress among parents. Based on the findings, training is essential to healthy family dynamics and infant's well-being, particularly for younger parents who support their infants at home. Also, regular updates on infant's condition could help reduce parents' stress and discomfort
Hashimoto Encephalopathy with an Unusual Presentation of Status Epilepticus Seizures: A Case Report
A 33 yr old man, previously diagnosed with hypothyroidism, presented with decreased level of consciousness and generalized
tonic-clonic (GTC) seizure to Namazi hospital, Shiraz, Iran, during April 2015. The patient later referred
with another episode of seizure like attack for which he received phenytoin, carbamazepine and levothyroxine and was
discharged. During his last admission, the patient was admitted with chief complaints of decreased consciousness and
four GTC attacks. On admission, the patients had aphasia, ataxia, loss of verbal communication, eye contact and
complete loss of obedience. Thyroid function tests showed low levels of T3 and T4 with high levels of thyroid stimulating
hormone. Other blood tests were all either normal or slightly abnormal. Lumbar puncture and CSF analysis had
a high titer of Anti-TPO antibodies. With high suspicion of Hashimoto encephalopathy, pulsed methyl prednisolone
(10 mg) was administered, however the patient showed little improvement. Therefore, plasmaphresis was started, to
which the patient showed dramatic response
