Sling for the sling: a new technique for long-term correction of severe congenital ptosis.

INTRODUCTION: Severe congenital ptosis poses a complex challenge for oculoplastic surgeons, requiring meticulous surgical intervention to restore eyelid function and improve aesthetic outcomes mainly by using frontalis sling approach. A crucial issue in frontalis sling surgeries is the sustainability of effect. PURPOSE: This retrospective study reports the outcomes of two surgical techniques for treating severe congenital ptosis in the paediatric age group: Silicon rods ptosis sling and a novel technique involving the use of Silicon rods with green braided polyester (Ethibond) sutures to secure the rods in place "sling for the sling". METHODS: The medical records of children who underwent frontalis suspension were reviewed in a retrospective fashion. We identified two groups; the first group (20 patients: 35 eyelids) had the traditional frontalis suspension surgery using silicone suspension set, the second group (14 patients: 25 eyelids) was operated using the new "sling for sling" technique. We used the postoperative marginal reflex distance-1 (MRD-1) as the primary outcome measure while the frequency of both wound related complications and recurrence were considered as secondary outcome measures. Post operative data were collected and compared after 1 month, 6 months, 12 months, and 18 months. RESULTS: Preliminary results indicate promising outcomes for both techniques, with significant improvement in eyelid elevation observed in both groups. However, the novel technique using Silicon rods with Ethibond sutures demonstrated enhanced sustainability, leading to a more durable outcome with significantly less recurrence. CONCLUSION: This study highlights the potential benefits of the novel technique in treating severe congenital ptosis and introduces an innovative approach to Silicone rods fixation to achieve a long-term corrective effect.

A longitudinal study of Middle East respiratory syndrome coronavirus (MERS-CoV) in dromedary camels.

BACKGROUND: Middle East respiratory syndrome coronavirus (MERS-CoV) was identified in humans in 2012. Since then, 2605 cases and 937 associated deaths have been reported globally. Camels are the natural host for MERS-CoV and camel to human transmission has been documented. The relationship between MERS-CoV shedding and presence of neutralizing antibodies in camels is critical to inform surveillance and control, including future deployment of camel vaccines. However, it remains poorly understood. The longitudinal study conducted in a closed camel herd in Egypt between December 2019 and March 2020 helped to characterize the kinetics of MERS-CoV neutralizing antibodies and its relation with viral shedding. RESULTS: During the 100-day longitudinal study, 27 out of 54 camels (50%) consistently tested negative for presence of antibodies against MERS-CoV, 19 (35.2%) tested positive and 8 (14.8%) had both, positive and negative test results. Fourteen events that could be interpreted as serological indication of probable infection (two seroconversions and twelve instances of positive camels more than doubling their optical density ratio (OD ratio) in consecutive samples) were identified. Observed times between the identified events provided strong evidence (p = 0.002) against the null hypothesis that they occurred with constant rate during the study, as opposed to clustering at certain points in time. A generalized additive model showed that optical density ratio (OD ratio) is positively associated with being an adult and varies across individual camels and days, peaking at around days 20 and 90 of the study. Despite serological indication of probable virus circulation and intense repeated sampling, none of the tested nasal swab samples were positive for MERS-CoV RNA, suggesting that, if the identified serological responses are the result of virus circulation, the virus may be present in nasal tissue of infected camels during a very narrow time window. CONCLUSIONS: Longitudinal testing of a closed camel herd with past history of MERS-CoV infection is compatible with the virus continuing to circulate in the herd despite lack of contact with other camels. It is likely that episodes of MERS-CoV infection in camels can take place with minimal presence of the virus in their nasal tissues, which has important implications for future surveillance and control of MERS-CoV in camel herds and prevention of its zoonotic transmission.

The impact of vitamin D, vitamin C, and zinc supplements on immune status among Jordanian adults during COVID-19: cross-sectional study findings.

BACKGROUND AND AIMS: Nutritional status is essential for the maintenance of the immune system, with malnutrition suppressing immunity. The aims of the current study were to assess the immune status of a group of Jordanian adults and to evaluate the association between vitamin C, vitamin D, and zinc consumption and the Immune Status during the COVID-19 pandemic. METHODS: A total of 615 adults Jordanian participants were enrolled in this study, an online- based cross sectional survey was used as a tool for this study. Data was collected by distributing the questionnaire form link through social media platforms. The association between ISQ score and the supplement intake pattern (daily, weekly, monthly and rarely) was assessed using multinomial logistic regression analysis, described as Odds ratio and 95% CI. RESULTS: Data have indicated that the majority of the participants did not take Vitamin D supplements during the pandemic (46.3%). Also, there was a significant association between the frequency of Vitamin D supplement intake and ISQ (r = 12.777; P < 0.05). Data showed that the majority of participants used vitamin C supplementation (49.4%). Also, there was a significant association between the frequency of Vitamin C supplement intake and ISQ (r = 12.797; P < 0.05). Data also have indicated that the majority of the participants did not increase their consumption of Zinc during the COVID-19 pandemic (55.6%). CONCLUSIONS: The findings of this study suggest a significant association between the frequency of Vitamin D, and vitamin C supplement intake and ISQ. Nutritional status is essential for the maintenance of the immune system, with malnutrition suppressing immunity.

Breastfeeding initiation and duration and acute otitis media among children less than two years of age in Jordan: results from a case-control study.

BACKGROUND: Acute otitis media (AOM) is one of the most common infectious diseases that affects children. Breastfeeding has been linked to a lower risk of AOM in the first three years of childhood. The aim of this study was to identify the association between exclusive breastfeeding and the development of acute otitis media (AOM) and investigate the influence of breastfeeding duration on the presence of AOM. METHODS: In a retrospective case-control study, a sample of 98 children (cases) who were diagnosed with AOM and 98 children (controls) who were not diagnosed with AOM and were younger than two years old were selected from the Jordan University Hospital. Medical records were used to identify children with AOM. For both the case and control groups, the children's mothers completed a self-administered questionnaire about factors linked to the incidence of AOM.The type of feeding and the duration of breastfeeding were assessed using a validated questionnaire. RESULTS: The data indicated that among children who developed AOM, 23.5%were artificiallyfed, while 22.4% and 13.3% were exclusively breastfed for 3 months and 6 months, respectively. Approximately 70.7% of the children without AOM were exclusively breastfed for 6 months, compared with only 29.3% of the children without AOM who were exclusively breastfed for 3 months.Logistic regression revealed that nonexclusive breastfeeding, exclusive breastfeeding for 3 months, and exclusive breastfeeding for 6 months were protective factors against AOM (OR = 0.23, 0.18, and 0.25, respectively; P < 0.05). A short duration of exclusive breastfeeding was considered a risk factor for the development of AOM (OR = 1.7, P < 0.05). CONCLUSIONS: The escalation of AOM is tightly connected to the early introduction of formula feeding in the first six months of life. Breastfeeding had a protective impact on the occurrence of AOM. Understanding factors that are associated with the occurrence of AOM in children may support the role of public health institutions and primary health care in the prevention and reduction of AOM episodes and the need for national health strategies to promote breastfeeding.

First detection of emerging HoBi-like Pestivirus (BVD-3) among some persistently infected dairy cattle herds in Egypt.

Bovine viral diarrhoea virus (BVDV) is a serious veterinary health concern worldwide. We conducted this study to determine the prevalence of persistent infections (PI) and identify the current strain among some dairy cattle herds in Egypt. A total of 240 serum samples were collected from six Egyptian provinces. Between 2019 and 2020, samples were tested by Enzyme linked immunosorbent assay (ELISA) for detection of PI animals, and then molecular characterization was performed. Six calves were found PI with a prevalence of 2.5% (6/240). Using molecular characterization, HoBi-like Pestivirus (BVD-3) was successfully identified in Egypt for the first time. Based on the BVD-3 reference strains on Genbank, the detected strains had an identity ranging from 98.8 to 99.6%. Partial nucleotide sequence of the 5'UTR gene for six tested samples was submitted to Genbank with accessions: OM324396, OM324397, OM324398, OM324399, OM3243100, and OM3243101.

Integrating Diabetes Prevention Education Among Teenagers Involved in Summer Employment: Encouraging Environments for Health in Adolescence (ENHANCE).

Type 2 diabetes (T2D) in youth is a growing healthcare and public health concern. It is costly, and youth suffer from disabling and deadly comorbid conditions at a faster pace than adult onset. However, T2D is preventable. The population of obese youth at greatest risk for T2D is of minority race/ethnicity and socioeconomically disadvantaged background, which creates barriers to health promoting lifestyles. Despite being the first line of prevention efforts for T2D, efficacious behavioral lifestyle interventions are still lacking at the community level. During the summers of 2016 and 2017, a study integrated obesity and diabetes prevention health education into TeenWorks summer employment program at Indy Urban Acres in Indianapolis, Indiana. Results were analyzed using paired sample t-tests. Participants (N = 168) had a mean age of 15.8 ± 0.7 years, 61% female, 13% Hispanic, 80% Black. By the end of the intervention, physical activity (p = 0.000) and prevention knowledge (p = 0.000) were significantly higher. Dietary intake (p = 0.204), self-efficacy (p = 0.58), food insecurity (p = 0.058) and depression screening scores (p = 0.809) were not significantly different. In light of the continuing childhood obesity epidemic and increasing prevalence of prediabetes and T2D in youth, there is a pressing need to understand and reduce barriers to obesity and diabetes prevention in high-risk populations. This study demonstrated the feasibility of integrating obesity and T2D prevention health education into a teen summer employment program.

Utility of the Enzyme-Linked Immunospot Interferon-γ-Release Assay to Predict the Risk of Cytomegalovirus Infection in Hematopoietic Cell Transplant Recipients.

The ability to distinguish allogeneic hematopoietic cell transplant (allo-HCT) recipients at risk for cytomegalovirus (CMV) reactivation from those who are not is central for optimal CMV management strategies. Interferon γ (IFN-γ) produced by CMV-challenged T cells may serve as an immune marker differentiating these 2 populations. We prospectively monitored 63 CMV-seropositive allo-HCT recipients with a CMV-specific enzyme-linked immunospot (ELISPOT) assay and for CMV infection from the period before transplantation to day 100 after transplantation. Assay results above certain thresholds (50 spots per 250 000 cells for immediate early 1 or 100 spots per 250 000 cells for phosphoprotein 65) identified patients who were protected against CMV infection as long as they had no graft-versus-host disease and/or were not receiving systemic corticosteroids. Based on the multivariable Cox proportional hazards regression model, the only significant factor for preventing CMV reactivation was a CMV-specific ELISPOT response above the determined thresholds (adjusted hazard ratio, 0.21; 95% confidence interval, .05-.97; P = .046). Use of this assay as an additional tool for managing allo-HCT recipients at risk for CMV reactivation needs further validation in future studies. Application of this new approach may reduce the duration and intensity of CMV monitoring and the duration of prophylaxis or treatment with antiviral agents in those who have achieved CMV-specific immune reconstitution.

An Evaluation of Inter- and Intraobserver Reliability of Cone-beam Computed Tomography- and Two Dimensional-based Interpretations of Maxillary Canine Impactions using a Panel of Orthodontically Trained Observers.

OBJECTIVES: To assess intra- and interobserver agreement when evaluating maxillary impacted canines using cone beam computed tomography (CBCT) and two-dimensional (2D) images through a panel of orthodontically trained observers. MATERIALS AND METHODS: An adult skull with permanent dentition was employed to perform 15 simulated maxillary canine impactions. Two sets of 2D and three-dimensional (3D) radiographic images were acquired. A panel of assessors including 11 PhD and MSc postgraduate orthodontic students evaluated maxillary impacted canines using a standard questionnaire with 11 categorical variables. Kappa (K) statistics as well as Krippendorff's alpha (α) coefficients were used for the analysis of reliability. RESULTS: A high level of intraobserver agreement was found for both the CBCT- and 2D-based interpretations. The 11 observers demonstrated a higher interobserver agreement for the CBCT-based interpretations than that of the 2D-based interpretations (α = 0.68 and 0.38 respectively). The employed 3D classifications canines was found to be reliable among observers on CBCT images for the labiopalatal position (K = 0.87), mesiodistal position, vertical position, labiopalatal inclination and mesiodistal inclination (α = 0.95, 0.83, 0.84 and 0.92 respectively). The 2D-based interpretations were not in agreement among the 11 observers, except for the mesiodistal position (α = 0.88) and mesiodistal inclination (α = 0.88). CONCLUSION: The intraobserver agreement was high for both the 2D- and the CBCT-based interpretations. The interobserver agreement for the CBCT-based interpretations was remarkably higher than that of the 2D-based interpretations. The utilized CBCT-based 3D classifications for the location and inclination of maxillary impacted canines were found reliable among observers.

Uveitis Profile in Children and Its Impact on Vision at Queen Rania Children's Hospital.

AIM: The aim of this study was to explore the patterns of pediatric uveitis and the types of ocular complications of uveitis and to determine the possible risk factors associated with visual impairment. METHOD: This was a cross-sectional study conducted at Queen Rania Children's Hospital between June 2020 and June 2023. All children diagnosed with uveitis were enrolled in the study. After collecting data from the patients and reviewing their medical records regarding age, gender, and past ocular and medical history, the patients were subjected to a detailed ophthalmic exam including best-corrected visual acuity (BCVA). Anterior segment exam using the slit lamp, intraocular pressure exam using Goldmann applanation tonometry, and posterior segment exam using 78 and 90 diopter Volk lenses were performed. Patients with other ocular diseases that affected visions not related to uveitis were excluded from the study. RESULTS: A total of 82 children, accounting for 130 eyes, were enrolled in this study, with ages ranging from 2 to 16 years (mean age 10.5±4.3 years). Among them, 27 were males, constituting 32.9% of the participants. Unilateral uveitis was observed in 34 eyes, representing 26.2% of cases. The mean age of uveitis onset was 6.9±1.9 years, and the mean disease duration was 4.8±0.4 years. The majority of cases i.e. 90.8% (n = 74) were non-infectious, with 92.3% (n = 76) classified as non-granulomatous and 79.2% (n = 65) categorized as chronic. Anterior uveitis was the most prevalent site of inflammation in 70.8% of cases (n = 58), followed by panuveitis in 20.0% of cases (n = 16), intermediate uveitis in 6.2% of cases (n = 5), and posterior uveitis in 3.0% of cases (n = 2). The cause of uveitis could not be identified in 40.0% (n = 33) of cases. Juvenile idiopathic uveitis emerged as the most commonly known disorder associated with uveitis in 40.0% (n = 33) of cases. Complications were identified in 52.3% (n = 43) of cases, with posterior synechiae being the most prevalent; 26.9% (n = 22) demonstrated an improvement in BCVA, while 21.5% (n = 18) experienced a decline in BCVA relative to the initial assessment Conclusion: Pediatric uveitis tends to manifest as anterior, chronic, bilateral, and non-granulomatous. Higher frequencies of severe visual impairment are linked to panuveitis, infectious and granulomatous uveitis, early-onset, long-duration cases, and male gender. The use of biologics has a positive effect, significantly improving or preserving visual acuity.

A Cross-Sectional Study Exploring the Relationship Between BMI and Nursing Students' Emotional Well-Being During the COVID-19 Pandemic.

Background: Having a weight problem can cause emotional distress, especially in students, who suffer from both issues at a high rate. As a result of the COVID-19 pandemic's negative impact on society, these problems can be significantly impacted. The study aims to investigate the relationship between nursing students' BMI and their mental well-being. Methods: A cross-sectional study was conducted on 423 students from the second through fourth baccalaureate years of Science of Nursing program - KSA. The instrument for the study was an online questionnaire distributed to the students via Google Forms during the academic year 2021-2022 to collect data on the emotional state of students directly as a result of COVID-19 restrictions and limitations. The statistical analysis was carried out through Chi-square test was used to compare categorical data between groups and the Pearson coefficient is used to determine the correlation between two quantitative variables with normal distribution. Results: There is a significant correlation between BMI with depression score, anxiety score and stress score. Higher BMI indicated 6.4 times more likeliness to have depression than lower BMI (OR = 6.4). Students who had higher BMI were 2.7 times more likely to have anxiety than those who had lower BMI (OR = 2.7), and 9.4 times more likely to have stress than those who had lower BMI (OR = 9.4). Conclusion: Study findings indicate that nursing students' BMI increases as depression, anxiety, and stress increase. During the COVID-19 pandemic, participants reported increased weight due to increased stress levels and increased eating. Students in nursing should be aware of the importance of adopting healthy habits and following a healthy lifestyle.

Effects of Ramadan Fasting on Glycaemic Control Among Patients with Type 2 Diabetes: Systematic Review and Meta-analysis of Observational Studies.

INTRODUCTION: The prevalence of type 2 diabetes (T2D) is increasing around the world. Although Muslims with a physical illness are exempted from fasting during the month of Ramadan, a great number still choose to fast, often without medical consultations. The aim of this systematic review and meta-analysis was to investigate the impact of observing Ramadan fasting (RF) on glycaemic control in patients with T2D. METHODS: The Web of Science, Scopus, EBSCOhost, CINAHL, ScienceDirect, Cochrane Library, ProQuest Central and Europe PubMed Central (Medline) databases were searched for relevant studies published between January 2000 and December 2021. Observational studies that examined the changes in body weight (BW) and glucose parameters (glycosylated haemoglobin [HbA1c] and fasting blood glucose [FBG]), before and after RF among different age groups with T2D were included in the systemic review and meta-analysis. Effect sizes for the tested outcomes were calculated as weighted mean difference (WMD), with their confidence intervals (CI). Quality assessment was examined using the National Heart, Lung, and Blood Institute (NHLBI) tool. RESULTS: Of the 1592 identified records, 12 studies conducted in Middle Eastern and Asian countries were eligible and included in the quantitative analyses. The quality of the retrieved studies was evaluated and found to range between fair (83%) and good (17%). These 12 studies included 5554 participants of whom 54% were males and 46% were females. Our pooled analysis demonstrated that HbA1c and FBG levels significantly decreased after RF when compared to the pre-fasting levels (WMD = 0.55 mg/dl, 95% CI 0.33-0.77, P < 0.00001, Ι2 = 93% and WMD = 12.42, CI 6.46-18.38, P < 0.0001, Ι2 = 81%, respectively). However, the difference in BW in fasting patients after RF versus the pre-fasting stage was non-significant. Although, young patients with T2D were enrolled in the 12 selected studies, we did not find any studies that solely focussed on this group. CONCLUSION: The impact of RF on adult patients with T2D is associated with favorable outcomes. However, future studies should evaluate data from young adults separately. In addition, it is essential to identify the effects of the number of fasting days (level of exposure), diet, level of physical activity and sleeping pattern on optimal glycaemic control. This information could be utilized by medical professionals as a non-pharmacological therapeutic method for management of diabetes in patients who are willing to practice fasting during Ramadan and other months of the year.

Post-gastric Sleeve Surgery Chronic Symptoms From a Sample of Patients in Saudi Community.

BACKGROUND: A common bariatric procedure known as gastric sleeve surgery can cause significant weight loss and co-morbid condition alleviation. However, patients could experience persistent problems such as gastrointestinal, musculoskeletal/neural, and psychiatric disorders after surgery. This study aims to identify the most prevalent chronic symptoms following sleeve gastrectomy among a sample of Saudi patients and the impact these symptoms have on patients' lives. METHODOLOGY: Patients who underwent gastric sleeve surgery at the Ensan Clinic, a facility specializing in gastroenterology, were the subjects of this retrospective cohort analysis. The study population consisted of patients who underwent gastric sleeve surgery, showed up for follow-up after the procedure, and met the inclusion and exclusion criteria. The data collection sheet is divided into seven sections. Sociodemographic information was required in the first section, gastric sleeve surgery information in the second, vital signs in the third, lab results in the fourth, past medical history in the fifth, current treatments in the sixth, and postoperative complications and chronic symptoms in the seventh and final sections. RESULTS: In 117 patients, the study evaluated the effects of gastric sleeve surgery. Participants had an average age of 40.21 years, and 61.5% were female. Regarding persistent symptoms after surgery, a sizable percentage of patients mentioned digestive issues such as GERD (44.4%), dyspepsia (60.7%), vomiting (23.1%), nausea (39.3%), and abdominal distention (45.3%). A total of 34.2% of patients reported experiencing anxiety, compared to 11.1% who said they had depression or 2.6% who said they had social issues. A few patients reported experiencing neurological or musculoskeletal issues, including exhaustion (7.7%), faintness (5.1%), back or joint discomfort (7.7%), and shortness of breath (8.5%). CONCLUSION: After undergoing gastric sleeve surgery, a sizable proportion of patients complained of various chronic symptoms and nutritional inadequacies, primarily gastrointestinal problems and musculoskeletal/neurological issues. The study's findings show a connection between these symptoms and surgery.

Short tandem repeat (STR) variation from 6 cities in Iraq based on 15 loci.

BACKGROUND: One thousand sixty-one individuals were sampled from the cities of Anbar, Baghdad, Basra, Diyala, Najaf, and Wasit in Iraq and typed for 15 forensic STRs to explore the genetic structure of Iraq and develop a forensic DNA database. The total number of alleles that were identified was 203. RESULT: Analyses of molecular variance (AMOVA) were then conducted Baghdad provides a good representation of the rest of the country, while Anbar is the most genetically distinct. The average heterozygosities of these loci was 0.779, homozygosities was 0.221, polymorphism information content was 0.77, power of discrimination was 0.927, and power of exclusion was 0.563. At these loci, a matching genotype will occur, on average, in 1 in 8.152 × 1017 individuals. For paternity tests, the average paternity probability for a matching profile is 99.9997%. CONCLUSIONS: These loci are appropriate for use in forensic and paternity testing for this population. Iraq is similar to other countries in the Middle East, particularly Iran and Turkey, and is more similar to Europe than either Asia or Africa.

West Nile virus: The current situation in Egypt.

Background and Aim: Due to climatic changes, arthropod-borne viruses have become a global health concern. In Egypt, West Nile virus (WNV) was initially detected in humans in 1950 and then in 1951, 1954, 1968, and 1989. Although WNV infection has been recorded in numerous Middle Eastern countries, its prevalence among the equine population in Egypt is unknown. This study aimed to investigate the current situation of vector-borne WNV in Egypt, estimate its seroprevalence, and assess the associated risk factors. Materials and Methods: We screened 1100 sera samples and nasal swabs from the same equids, 156 mosquito pools, and 336 oropharyngeal and cloacal swabs from migratory birds for WNV. The sera were investigated for the presence of immunoglobulin G (IgG) and immunoglobulin M (IgM) against WNV-prE. Real-time reverse transcription-polymerase chain reaction was used to detect WNV RNA in the nasal swab samples, mosquito pools, and migratory birds' oropharyngeal and cloacal swabs. Results: The seroprevalence showed positive IgG in sera samples collected from different districts. The data showed that horses were 1.65-fold more susceptible than donkeys, with male being 1.45 times more susceptible than females. Moreover, the tested equids samples were divided into three groups based on their age: <5 years, 5-10 years, and >10 years. The 5-10-year group was 1.1 and 1.61 times more vulnerable to infection than the <5- and >10 year groups. All the sera samples were negative for IgM. The nasal swabs from equids, oropharyngeal and cloacal swabs from migratory birds, and mosquito samples tested negative for WNV by molecular detection. Conclusion: Based on the obtained data, we recommend that effective control programs should be implemented to enable epidemiological investigations and understand the current situation of WNV in Egypt.

Cognitive behavioral therapy for institutionalized elders complaining of sleep disturbance in Alexandria, Egypt.

BACKGROUND: Behavioral interventions such as cognitive behavioral therapy (CBT) are among the most widely used nonpharmacologic alternatives for the treatment of insomnia. PURPOSE: The aim of this study was to determine the prevalence of insomnia, factors affecting it, and the impact of a cognitive behavioral therapy for institutionalized elders complaining of sleep disturbance in Alexandria, Egypt. METHODS: This study was done through two phases. A cross-sectional design was used in the first phase to detect the prevalence of sleep problems and their correlates among the elderly, then pretest-posttest design was used to apply an intervention program to the elders who suffered from insomnia. A pre-designed structured interview questionnaire was presented to the participants. The main outcome measure was sleep quality, as measured by the Pittsburgh Sleep Quality Index. RESULTS: The study included a total of 210 elders (97 males and 113 females), with a mean age of 72.2 ± 5.3 years, about two thirds of them were poor sleepers (63.3%). The results show that after carrying out the behavioral therapy for the elders, the percentage of poor sleepers decreased from 63.3% to 46.2%. Two variables (educational level and female sex) proved to be statistically significantly related to the improvement in sleep quality. CONCLUSIONS: A goal of this intervention program was considerably achieved. Importantly, the intervention appears to improve sleep quality among the elders. Data from this study re-enforce the continuing need for more sleep educational programs that are intended to attract the attention of elders especially those institutionalized.

Blastocystis hominis as a contributing risk factor for development of iron deficiency anemia in pregnant women.

Intestinal parasitic infection increases the risk of developing iron deficiency anemia (IDA) during pregnancy. The objective of this study was to assess Blastocystis hominis as a contributing risk factor for development of IDA in pregnant women. A total of 200 fecal specimens from 120 pregnant women with IDA (mean Hb = 9.6 g/dl), and 80 non-anemic controls were examined for Blastocystis. Fecal specimens were examined by the formalin/ethyl-acetate concentration technique, iron hematoxylin staining, modified Ziehl-Neelsen acid-fast staining, and by the in vitro cultivation technique for Blastocystis. Frequency of Blastocystis infection, detected microscopically and by the in vitro culture technique, was significantly higher in IDA study group (n = 48; 40%) compared to non-anemic controls (n = 5; 6.3%; P < 0.0001), and 26.5% (n = 53) in all study subjects. Among the 48 cases, Blastocystis without other intestinal parasitic infections was detected in 41 cases (34.2%), while seven cases (5.8%) with Blastocystis were coinfected with other intestinal parasites which included Giardia and Cryptosporidium (1.7% each), and Entamoeba sp., Ascaris, and Trichuris (0.8% each). The mean Hb level of the 48 Blastocystis-infected cases was 9.2 g/dl (mild anemia). While the other 72 IDA cases with no infection had mean Hb of 10.0 g/dl (mild anemia), with a significant difference in mean Hb level between Blastocystis-infected and the non-infected IDA cases (P < 0.0001). Furthermore, among the 48 Blastocystis-infected IDA cases, the mean Hb of the 41 Blastocystis-infected cases without other intestinal parasitic co-infection was 9.1 g/dl (mild anemia), while the mean Hb level of the 7 Blastocystis-infected cases with other intestinal parasitic co-infection was 8.7 g/dl (moderate anemia). Findings of the current study showed that B. hominis infection contributes to the development of IDA in pregnant women. Hence, parasitological diagnostic tests are recommended in routine examination at all antenatal clinics.

Inhibitory effect of Ferula asafoetida L. (Umbelliferae) on Blastocystis sp. subtype 3 growth in vitro.

Asafoetida is an oleo-gum-resin obtained from many Ferula species and frequently used in traditional medicine. The current study aimed to evaluate the activity of asafoetida against the in vitro growth of Blastocystis sp. Asafoetida as powder-form (Ap) and oil-form (Ao) extracts at concentrations of 2, 4, 8, 16, and 20 mg/ml and 5, 10, 25, 40, and 50 mg/ml, respectively were incubated with isolates of Blastocystis sp. subtype 3 for 24, 72, and 144 h and compared to the reference antiprotozoan drug metronidazole at concentrations of 10, 100, and 500 µg/ml. Asafoetida either as Ap or Ao decreased counts and viability of all tested isolates of Blastocystis sp. subtype 3 which was confirmed by microscopy. The degree of the inhibitory effect was dependent on the concentration, form, as well as the time of incubation with asafoetida extracts. The lowest concentrations of Ap and Ao that caused complete (100 %) inhibition of Blastocystis growth and highest (100 %) percentage inhibition of multiplication was 16 and 40 mg/ml, respectively; mean counts at these concentrations either did not differ or decreased significantly when compared to metronidazole control (p < 0.05). Also, the parasites did not resume growth after re-cultivation in asafoetida-free medium when examined further after 48, 72, and 144 h of cultivation. These findings demonstrate the potential of phytomedicine asafoetida as a potent natural alternative for treatment of Blastocystis sp.infection.

The Combined Use of Silicone and Green Braided Polyester Suture (Ethibond) versus Silicone or Ethibond Alone for Frontalis Suspension Surgery in Children.

PURPOSE: This study aimed to report the outcomes of correcting severe congenital blepharoptosis by frontalis suspension using combined silicone tube and 2-0 green braided polyester suture (Ethibond), and to compare the results with those of silicone rod alone and Ethibond suture alone. PATIENTS AND METHODS: The medical records of patients below 16 years who underwent frontalis suspension were retrospectively reviewed. Three groups of patients were identified; group I (16 patients: 22 eyelids) had frontalis suspension surgery using silicone suspension set, group II (18 patients: 25 eyelids) underwent the surgery using Ethibond suture, and group III (15 patients: 23 eyelids) was operated on using combined silicone and Ethibond suture. The primary outcome measures were postoperative marginal reflex distance-1 (MRD-1) and postoperative symmetry, and the secondary outcome measures were the occurrence of complications; mainly recurrence and wound-related complications. The follow-up data were collected after 1 week, 1 month, 6 months, 12 months and every 6 months thereafter. RESULTS: The follow-up period ranged from 18 to 36 months. By the last follow-up visit, 13 eyelids in silicone group (59%), 11 eyelids in the Ethibond group (44%), and 13 eyelids in the double sling group (57%) achieved good surgical correction with MRD1 ≥3mm; these differences were not statistically significant. The difference in symmetry among the three groups was not significant. The highest rates of recurrence (44%) and wound-related problems (8%) were encountered in the Ethibond group, while the silicone group had no cases of wound-related problems. The lowest recurrence rate (26.1%) was in the double sling group but those differences were not significant. CONCLUSION: Combined use of silicone and Ethibond suture in frontalis suspension surgery could offer lower recurrence rate and good final surgical outcome when compared to silicone rod or Ethibond suture alone.

An-m-Health Intervention Using Smartphone App to Improve Physical Activity in College Students: A Randomized Controlled Trial.

Using m-Health apps can provide researchers and others with an effective way for improving physical activity (PA) and healthy lifestyle behaviors. The promotion of health should move from a model focused on the physical and biological basis of illness and towards a focus on the behavioral changes that support health. Therefore, the aims of the current study were to improve PA (step-counts) and body weight using a theory-based m-Health app. A 12-week randomized treatment trial was carried out at Texas A&M University, Texas, college station. College students (n = 130) were recruited. They were randomized in an equal ratio of 1:1 to intervention (m-Health app) (n = 65) and control (n = 65) conditions. The response rate was (87.6%). Both groups utilized a Smartphone app. The intervention group received PA goals of (10,000 steps/day), using an m-Health app. The control group was provided with information related to daily recommended PA levels. The primary change was daily step count between the baseline and follow-up. The secondary outcome was the body mass index (BMI). Descriptive statistics were used to summarize the baseline differences between the control and intervention groups. Independent sample t-test were used for comparison between the intervention and control groups. Post-intervention PAs were higher for the intervention group (mean = 54,896.) vs. control group (mean = 45,530.12; p < 0.05). The intervention group's step-counts increased significantly (pre-mean = 40,320.38 steps per week; post-mean = 54,896.27 steps per week, p < 0.05). The body-weight changes were significant among the intervention group (p < 0.05). m-Health apps can increase PA and improve body weight, with goal setting and feedback as key intervention components. Future studies should personalize PA goals and feedback.

Evaluation of the diagnostic accuracy of CBCT-based interpretations of maxillary impacted canines compared to those of conventional radiography: An in vitro study.

BACKGROUND: Cone-beam computed tomography (CBCT) imaging has become widespread in diagnosing impacted teeth in the context of orthodontic treatment. However, the diagnostic accuracy of this 3D imaging tool has not been comprehensively evaluated yet. The objectives of this study were: (1) to investigate the diagnostic accuracy of employing CBCT imaging in the three-dimensional (3D) localization of maxillary impacted canines compared to the use of traditional two-dimensional (2D) imaging, and (2) to calculate sensitivity, specificity and diagnostic accuracy values for specific variables assessed in 3D and 2D. MATERIAL AND METHODS: An adult cadaver skull with permanent dentition was employed and 15 simulations of maxillary canine impactions were created. Two sets of 2D and 3D radiographic images were obtained. The two sets of images were evaluated by eleven postgraduate orthodontic students. Cochran's Q tests, Friedman's tests, and then McNemar's, McNemar-Bowker's and Wilcoxon tests were used to compare Observers' responses in 3D and 2D with the gold standard values. RESULTS: Insignificant differences were found between the CBCT-based interpretations and the gold standard (GS) concerning the labiopalatal position (P=0.34), labiopalatal and mesiodistal inclination (P=0.66 and P=0.194, respectively), whereas the mesiodistal and vertical positioning showed significant differences (P=0.002 and P<0.001, respectively). The percentages of agreement between the 2D- and 3D-based interpretations were acceptable in terms of labiopalatal and mesiodistal inclinations (71.5% and 77.5%, respectively). Remarkably higher values of sensitivity, specificity and diagnostic accuracy for the CBCT-based interpretations were observed. CONCLUSIONS: The diagnostic accuracy of CBCT outweighed that of 2D radiography in the labiopalatal localization of maxillary impacted canines, contact relationship with adjacent teeth and resorption diagnosis. 3D-based assessments and the gold standard had high percentages of agreement especially for the labiopalatal position evaluation and the proximity diagnosis.
