The Effect of Enhanced Recovery After Surgery Protocol on Surgical Site Infections in Liver Transplantation.

Background: Liver surgeries are treatment modalities that require careful pre- and postoperative follow-up for both the surgeon and the patient. Infections are the leading causes of morbidity and mortality after liver transplantation. Infections are the most frequent cause of death between 30 and 180 days after liver transplantation. We aimed to investigate the effect of the Enhanced Recovery After Surgery (ERAS) protocol on the prevention of infections in liver transplant patients. Patients and Methods: The study included patients who underwent liver transplantation in Ataturk University Organ Transplantation Center between 2017 and 2022. Two patient groups with and without ERAS were formed. Blood and urine cultures were collected retrospectively, and those with positive blood cultures for bacteremia were recorded as infection development. The development of infection between the two groups was statistically compared. Also, all patients' length of intensive care stay, length of hospital stay, and duration of antibiotic use were recorded. These parameters were compared between both groups. Results: There was a statistically significant difference between the two groups in terms of infection development (p: 0.01). There was a statistically significant difference between the two groups in terms of duration of antibiotic use and length of hospital stay (Mann-Whitney U test; p: 0.00, p: 0.04, respectively). There was no statistically significant difference between the two groups in terms of length of intensive care stay. Conclusion: We concluded that the introduction of an ERAS protocol was associated with fewer infections, thus shortening the duration of antibiotic therapy and length of hospital stay, although the standardization of the protocols is difficult, especially in liver transplants.

An investigation on protection properties of Tantalum (V) oxide reinforced glass screens on unexposed breast tissue for mammography examinations.

INTRODUCTION: The utilization of radiation shielding material positioned between the both breasts are crucial for the reduction of glandular dose and the safeguarding of the contralateral breast during mammographic procedures. This study proposes an alternative substance for shielding the contralateral breast from radiation exposure during mammography screening. METHODS: In this study, we present an analysis of the shielding effectiveness of transparent glass that has been doped with Tantalum (V) oxide encoded as BTZT6. The evaluation of this shielding material was conducted using the MCNPX code, specifically for the ipsilateral and contralateral breasts. The design of the left and right breast phantoms involved the creation of three-layer heterogeneous breast phantoms, consisting of varying proportions of glandular tissue (25%, 50%, and 75%). The design of BTZT6 and lead-acrylic shielding screens is implemented using the MCNPX code. The comparative analysis of dose outcomes is conducted to assess the protective efficacy of BTZT6 and lead-acrylic shielding screens. RESULTS: The utilization of BTZT6 shielding material resulted in a reduction in both breast dose and skin dose exposure when compared to the lead-acrylic shield. CONCLUSION: Based on the findings acquired, the utilization of BTZT6 shielding material screens during mammography procedures involving X-rays with energy levels ranging from 26 to 30 keV is associated with a decrease in radiation dose. IMPLICATIONS FOR PRACTICE: It can be inferred that the utilization of BTZT6 demonstrates potential efficacy in mitigating excessive radiation exposure to the breasts and facilitating the quantification of glandular doses in mammography procedures.

Effect of Nintedanib on healing and fibrosis in rats with experimentally induced urethral injury.

AIM: We aimed to determine the effectiveness of Nintedanib treatment, which has known antifibrotic effect, in preventing fibrosis after urethral trauma. MATERIAL AND METHODS: Twenty-three adult Sprague-Dawley rats were divided randomly into 3 different groups: Sham, Urethral injury group (UI) and Urethral injury+ Nintedanib (UI+N). The urethral injury model was made with a pediatric urethrotome knife. Nintedanib was administered at a dose of 50mg/kg by oral gavage for 14 days at the same time every day. After 14 days of treatment, all rats were performed penectomy under general anesthesia. Urethral tissue was evaluated histopathologically (congestion, inflammatory cell infiltration and spongiofibrosis) and immunohistochemically (transforming growth factor (TBF) Beta-1 and vascular endothelial growth factor receptor 2 (VEBFR2)). RESULTS: Histopathological findings: Group UI had higher scores in all categories (congestion, inflammatory cell infiltration, and spongiofibrosis), followed by Group UI+N and Group Sham, respectively. A statistically significant difference was found between Group UI and Group UI+N in terms of the scores of histopathological parameters (p<0.05). Immunohistochemical findings: Group UI had higher scores in both categories, followed by Group UI+N and Group Sham, respectively. A statistically significant difference was found between Group UI and Group UI+N in TGF Beta-1 and VEGF scores (p<0.05). CONCLUSION: We found that Nintedanib administration after urethral trauma reduced inflammation and fibrosis histologically and immunohistochemically. The positive effect of Nintedanib on inflammation and fibrosis after urethral trauma reported in this animal study is encouraging for a potential clinical human application.

An unusual case of oropharyngeal mature teratoma in a kitten.

Background: Extragonadal teratoma in the head and neck region is unusual in veterinary medicine. So far, only one case of oropharyngeal teratoma has been reported in a cat. Case description: In this report, a 5-month-old kitten was brought to the clinic with the complaint of difficulty breathing, food intake, and oropharyngeal mass. In clinical examination, there was a large mass, protruding from the localization included left buccal mucosa, soft palate, and extending into the oropharynx but no cranial extension was observed in CT scans. The mass was completely resected. Macroscopically, the mass measured 4.5 × 6.5 cm2 and contained solid and cystic areas associated with soft and hard tissue components. Findings/treatment and outcome: Histopathology revealed an extragonadal solid-cystic (grade 0) oropharyngeal mature teratoma containing structures from endoderm, mesoderm, and ectoderm. After an 8-month follow-up control period, no signs of recurrence were observed. Conclusion: The case was deemed worthy of being presented with its clinical, radiological, and pathological findings, and complete resection was curative for mature teratoma.

Health status, coronaphobia, quality of life, anxiety and depression in patients with lymphedema during COVID-19 pandemic.

Covid-19 has physical damage as well as serious impact on the mental health in the community. Symptoms such as anxiety, depression, fear, stress, and sleep problems were more commonly reported during Covid-19 pandemic. The aim of this study was to assess the health status, psychological conditions, quality of life, and possible risk factors of patients with lymphedema during the pandemic. The study included male and female patients aged ≥18 years with primary or secondary upper or lower extremity lymphedema (stage 1, 2, or 3) who were followed in our outpatient clinic. The patients were interviewed by phone. Health and social status were examined using a questionnaire, Covid-19 phobia was assessed using Covid-19 Phobia Scale (C19P-S), and quality of life was assessed using Lymphedema Quality of Life Questionnaire Arm or Leg (LYMQOL). Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale (HADS). The HADS scores showed that 35% of the patients had severe risk for depression and 10% had severe risk for anxiety. Factors with negative effect on HADS were lower education level, sedentary lifestyle, failure to perform lymphedema exercises, weight gain, and lymphedema duration. The C19P-S scores were higher indicating greater phobia in the overall score and subscores in patients with primary lymphedema and secondary lymphedema without malignancy, younger patients, those who are not able to walk regularly, and those who are not able to perform self manual lymphatic drainage (self-MLD). Factors with negative effects on LYMQOL were stage 3 lymphedema, female gender, younger age, and longer disease duration. Patients who performed regular self-MLD and lymphedema exercises demonstrated positive effects on LYMQOL. The results of this study suggest that patients with lymphedema affected by the COVID-19 pandemic are mostly younger patients, individuals with primary lymphedema, individuals with non-malignant etiology, individuals who unable to perform regular walking, and those unable to perform self- MLD.

The relationship between dimensions of the Eustachian tube and acquired attic cholesteatoma.

OBJECTIVE: This study investigated the relationship between physical dimensions of the Eustachian tube and the emergence of primary attic cholesteatoma. METHODS: A total of 31 patients with unilateral attic cholesteatoma were selected for radiological comparison. Standard point measurements as well as specific measurements were performed using imaging software. The length, narrowest diameter and bony segment volume, and pharyngeal orifice diameter of both sides of the Eustachian tube (attic cholesteatoma and healthy control ears) were measured and compared. RESULTS: Comparison of the values did not reveal any statistically significant difference between the attic cholesteatoma ears and the healthy control ears in terms of: Eustachian tube height, narrowest diameter, bony segment volume or pharyngeal orifice diameter. CONCLUSION: No statistically significant difference was found between the cholesteatoma ears and the healthy control ears in terms of the osseous Eustachian tube size. The findings indicate that the Eustachian tube bony segment dimensions and pharyngeal orifice diameter are not factors in attic cholesteatoma development.

The effect of skeletal muscle area and attenuation in patients with sternum fracture due to blunt chest trauma.

OBJECTIVE: This study aims to retrospectively investigate the imaging features of patients with sternum fracture (SF) and concomitant organ injuries. We also aimed to evaluate the potential prognostic effect of skeletal muscle area (TMA) and muscle attenuation (MuA) values. PATIENTS AND METHODS: Computed tomography (CT) images of patients with SF were re-evaluated by two observers (Observer-1 and 2). Observer-3 has measured TMA and MuA values. Observer-1 has repeated the measurements blindly to the first measurement results to evaluate the inter-observer agreement. The length of hospital stay, death, hemiplegia, or quadriplegia were investigated from the archives. Mann-Whitney U-test or Student's t-test was used to investigate the relationship between linear variables. The intraclass correlation coefficient (ICC) score was used to evaluate the interobserver agreement. Logistic regression analysis was used to estimate the relative effect of variables by calculating unadjusted odds ratios (ORs) for categorical outcomes. RESULTS: Sixty-five patients had SF and 53 patients had SF and concomitant organ injuries. The most common injuries accompanying SF were rib fracture (73.58%) and lung contusion (60.38%). Manubrium fracture was the most common fracture location (52.3%), and 18 patients (27.7%) had displaced SF. Eight patients (15.1%) were discharged with plegia and five (9.4%) died. Hemothorax, displaced SF and decreased MuA were predictors of prolonged hospital stay, and the presence of cardiac contusion, displaced SF, hemothorax, and vertebra body fracture were independent factors for death. CONCLUSIONS: The presence of a displaced SF and decreased MuA value are important prognostic factors in patients with SF.

Microbulb and plantlet formation of a native bulbous flower, Lilium monodelphum M. Bieb, var. Armenum, through tissue culture propagation.

The plant Lilium monadelphum M. Bieb. var. armenum (Miscz. Ex Grossh) Davis et Henderson recognized as the caucasian lily grows in the Eastern Black Sea Region and is a perennial bulbous species belonging to the Liliaceae family. Its flowers, bulbs, and volatile oils are used in the perfume industry, as a folk medicine to treat eczema and abscess therapy, and as a tranquilizer among regional people respectively. Hence, it is commonly collected from the wild and could become endangered. In this study, we explored the optimal hormone treatment for efficient and rapid induction and production of this species in tissue culture. Explants taken from bulbs were cultured in Murashige and Skoog medium (MS medium, 1962) and modified with TDZ (thidiazuran) (0.5; 1.0; 2.0; 3.0; 5.0 mg/L), after which adventitious buds used for explants during the second stage were subcultured 4 different media supplemented with different concentrations of PAC (paclobutrazol) (0.1; 0.5; 1.0; 2.0 mg/L) to induce microbulbs formation. Microbulbs were cultured in a rooting medium containing IBA (0.5;1.0 mg/L). The highest bud regeneration was observed in medium containing 3.0 mg/L TDZ, 0.25 mg/L NAA and 0.1 mg/L GA3; the highest microbulb formation was observed in medium containing 2.0 mg/L PAC, 0.2 mg/L NAA, and 0.1 mg/L GA3. Besides, plant development from the microbulb was successful for roots in a medium containing 0.5 mg/I IBA and all of the plantlets obtained in tissue culture survived when transferred to the soil.

Sinonasal effects of external dacryocystorhinostomy.

OBJECTIVE: External dacryocystorhinostomy is thought to cause mucociliary dysfunction by damaging the mucosa, in turn affecting ciliary activity and mucus quality. This study investigated the effect of external dacryocystorhinostomy on sinonasal function. METHODS: Patients scheduled for unilateral external dacryocystorhinostomy who underwent endoscopic nasal examination and paranasal sinus computed tomography were included in this study. A saccharine test was performed on the planned surgical side and the mucociliary clearance time was determined. The sinonasal quality of life was measured in all patients, pre-operatively and at six months post-operatively, using the Sino-Nasal Outcome Test-22. The Lund-Kennedy endoscopic score was also determined in all patients, both pre- and post-operatively. RESULTS: The study comprised 28 patients (22 females and 6 males). A statistically significant difference was found between the pre- and post-operative saccharine test results (p = 0.006), but not between the pre- and post-operative Sino-Nasal Outcome Test-22 scores (p > 0.05). CONCLUSION: This study is one of only a few to investigate the effect of external dacryocystorhinostomy on sinonasal function. The results showed that external dacryocystorhinostomy impairs mucociliary clearance. The surgical procedure is well tolerated and does not significantly change nasal symptom scores.

Evaluation of mothers' opinions on appetite and body shape perception of their children.

OBJECTIVES: In this study, we aimed to evaluate how mothers perceived the appetite and body shape of their children using gender- and age-specific development sketches. STUDY DESIGN: The study design used in the study is a single-centred descriptive study. METHODS: We included 153 children aged 2-14 years and their mothers who attended family medicine polyclinic outpatient services, for any reason, at the University of Health Sciences, Sisli Hamidiye Etfal Teaching and Research Hospital, Istanbul, Turkey, between February 2019 and April 2019. Weight and height measurements of both the children and their mothers were taken. In addition, the mothers completed the sociodemographic data form and were asked to select an image from the gender- and age-specific development sketches that best represented their child's body shape. Participants were divided into four groups by their body mass index (BMI) in accordance with criteria from the Centres for Disease Control and Prevention. Results were compared using appropriate statistical procedures. RESULTS: A significant weak positive correlation was observed between maternal BMI and child BMI (r = 0.166, P = 0.041). When the maternally perceived BMI (determined by the age-specific development sketches) was compared with the actual BMI values of children, mothers perceived their underweight children to be in higher BMI groups, whereas the overweight and obese children were perceived to be in lower BMI groups. The results were similar when the same comparison was made for the mother's expectation (i.e. the body shape the mother desired for their child). CONCLUSIONS: When mothers were asked to visually evaluate the body shape of their children, their responses were inaccurate compared with both the actual data and the researcher's evaluation. Obtaining verbal assessments from mothers about their children (e.g. an assessment of the child's bodily appearance) is important for physicians to make correct referrals and also for public health policies. It is valuable for mothers to correctly interpret the weight status of their children, thus enabling early diagnosis and treatment, and preventing future health consequences.

Prevalence and Associates of Fear of Falling among Community-Dwelling Older Adults.

OBJECTIVES: We aimed to study the prevalence of fear of falling (FOF), and its association with physical performance, functionality, frailty, sarcopenia, and a variety of geriatric syndromes including cognitive impairment, depression, quality of life and hearing. DESIGN: Retrospective, cross-sectional study. SETTING: Community-dwelling older adults applied to the geriatric outpatient clinic of a university hospital. PARTICIPANTS: A total of 1021community-dwelling older adults >= 60 years of age applying to the geriatric outpatient clinic of a university hospital. MEASUREMENTS: We screened for falls and FOF by single close-ended questions. We performed screening and assessment of probable sarcopenia by SARC-F test and handgrip strength evaluation according to EWGSOP2. We used timed up and go test (TUG), usual gait speed (UGS) for physical performance, and Katz- activities of daily living (ADL) and Lawton-Brody instrumental activities of daily living (IADL) for functional evaluation. We screened anxiety with the Generalized Anxiety Disorder-7 scale. RESULTS: The prevalence of FOF was 44.6% and falls, 37.7%. Prevalence of FOF in sarcopenia screening positive participants was 30.1%; in probable sarcopenic (35/20 kg) participants, 43.9%; in those with undernutrition, 45.7%; in fallers, 51.1%; in females, 80.4%; and in prefrail/frail was 74.7% Multivariate regression analyses revealed that female sex (OR=4.1, 95%CI= 2.0-8.4, p<0.001), anxiety (OR=2.7, 95%CI= 1.1-6.5, p=0.03) and ADL limitation (OR=2.5, 95%CI= 1.03-6.3, p=0.04) were independent associates of FOF. CONCLUSION: FOF accompanied by fall experience or not is prevalent in community-dwelling older adults. It is associated with anxiety and ADL limitations apart from the female sex.

The Effects of 2100 MHz Radio Frequency Radiation on Thyroid Tissues

ABSTRACT Objective: To reveal the effect of 2100 MHz radio frequency (RF) radiation on thyroid tissues of rats in the 10 days (group E1) and 40 days (group G1) exposure groups. Methods: In this study, 30 healthy female Wistar albino rats, weighing 200−256 g each, were used. The animals were randomly divided into four groups (E1, E2, G1 and G2). Groups E2 and G2 served as the control groups. The exposure groups were exposed to 2100 MHz RF radiation emitted by a generator, simulating a 3G-mobile phone for 6 hours/day, 5 consecutive days/week, at the same time of the day (between 9 am and 3 pm), for 10 days (group E1) and 40 days (group G1). Results: Catalase and xanthine oxidase enzyme activities were compared between the groups E1 and E2; it was found that the difference was statistically significant (p < 0.05). Between the groups G1 and G2, the difference was found to be significant with respect to catalase activities. Tissue samples of the early and late groups showed no serious pathological findings in the histopathological examination. Conclusion: We believe that comprehensive, clinical and experimental studies are needed to assess the effect of the RF exposure duration and dosage of exposure on thyroid tissues.

Push down technique with ostectomy.

PURPOSE: Rhinoplasty is one of the most commonly performed aesthetic surgeries among patients who are admitted to plastic surgeons. Recent research has focused on dorsal preservation in hump reduction and consequently dorsal preservation techniques have become more popular. The current study aimed to revise the push down technique by adding ostectomy. PATIENTS AND METHODS: In the present retrospective study, data from patients who underwent rhinoplasty to fix a nasal hump were assessed. All patients were administered the push down technique with ostectomy. Following these inclusion and exclusion criteria, the records of 52 patients were assessed (45 females and 7 males). The median age of the patients was 22.2 years. Patients were evaluated using the "Rhinoplasty Outcome Evaluation" (ROE) questionnaire both before surgery and 12 months after surgery. The follow-up period ranged between 13 and 21 months (median of 15.1 months). RESULTS: Patients were evaluated before surgery and after one year of surgery by the ROE scale. The median of the ROE score before surgery was 63.4. The median score after one year of surgery was 91.6. Thus, the ROE score significantly increased 12 months after surgery (P<0.001). CONCLUSIONS: This study was the first to demonstrate the benefits of performing the push down technique with ostectomy in terms of obtaining a wider nasal cavity. In addition, it can be assumed that the disadvantage of using the push down technique can be overcome with ostectomy.

Evaluation of the bilateral cardiac afferent distribution at the spinal and vagal ganglia by retrograde labeling.

The identity of sensory neurons innervating the heart tissue and the extent of information reported to the brain via these neurons are poorly understood. In order to evaluate the multidimensional distribution and abundance of the cardiac spinal and vagal afferents, we assessed the retrograde labeling efficiency of various tracers, and mapped the cardiac afferents qualitatively and quantitatively at the bilateral nodose ganglia (NGs) and dorsal root ganglia (DRGs). From the five different retrograde tracers evaluated, Di-8-ANEPPQ yielded reproducibly the highest labeling efficiency of cardiac afferents. We demonstrated specific cardiac afferents at NGs and C4 to T11 DRG segments. Next, the 2D reconstruction of the tissue sections and 3D imaging of the whole NGs and DRGs revealed homogeneous and bilateral distribution of cardiac afferents. The quantitative analyses of the labeled cardiac afferents demonstrated approximately 5-6% of the soma in NGs that were equally distributed bilaterally. The neuronal character of Di-8-ANEPPQ labeled cells were validated by coimmunostaning with pan-neuronal marker Tuj-1. In addition, the cell diameters of labeled cardiac sensory neurons were found smaller than 20 µm, implying the nociceptor phenotype confirmed by co-labeling with TRPV1 and Di-8-ANEPPQ. Importantly, co-labeling with two distinct tracers Di-8-ANEPPQ and WGA-647 demonstrated exclusively the same cardiac afferents in DRGs and NGs, validating our findings. Collectively, our findings revealed the cardiac afferents in NGs bilaterally and DRGs with the highest labeling efficiency reported, spatial distribution and quantitation at both 2D and 3D levels, furthering our understanding of this novel neuron population.

Treatment of severely decayed anterior primary teeth with short-post technique (Mushroom Restorations) under general anesthesia.

AIMS: The aim of this study was to evaluation the treatment success of the short post technique (mushroom restoration) using a composite resin in severely decayed primary anterior teeth after 6, 12, and 18 months after treatment. METHODS: Eighteen children aged 3-5 years with severely decayed primary maxillary anterior teeth (60 anterior maxillary primary teeth in total) were included. Patients were treated under general anesthesia (GA). After pulpectomy, a "mushroom shape" was formed in the root canals for the purpose of retention, and the root canals were filled with zinc oxide-eugenol (ZOE), and the teeth were restored with composite resin. The status of treatment was evaluated clinically and radiographically for periapical radiolucency, pathological root resorption, marginal fracture, and loss of restoration for each treated tooth. All findings were recorded. RESULTS: As a result of the evaluation criteria, the success rates at 6, 12 and 18 months were 86%, 80%, and 71%, respectively. None of the teeth showed apical radiolucency or pathological root resorption at the end of the 18th month period. CONCLUSION: The short-post (mushroom restorations) technique is a clinically acceptable alternative method for restoration of severely decayed primary teeth. This study supports the feasibility of treatment with this technique for pediatric patients treated under GA.

Evaluation of MicroRNA-124 Expression in Renal Cell Carcinoma.

The Wingless/INT (WNT) signaling network has roles in renal cancer development. It was shown that the tumor-suppressor microRNA-124 (miR-124) is associated with the Wnt pathway. Thus, we aimed to measure miR-124 expression levels to evaluate whether it is a prognostic marker or a potential treatment strategy. Thirty tumor and 30 surrounding healthy kidney tissues from the same subjects diagnosed with renal cell carcinoma (RCC), were included in the study. The expression levels of miR-124 were measured with real-time polymerase chain reaction (qPCR) and determined by the 2-ΔΔCT method. The Statistical Package for Social Science (SPSS) version 22 program was used for statistical analyses and a p value of 0.05 was considered to be statistically significant. The expression levels of miR-124 was found to be about 3-fold lower in tumors than in healthy tissues (p 0.001) and decreased expression levels correlated with tumor stage, tumor diameter, body mass index (BMI) and neutrophil values (p 0.05). Our results showed that miR-124 expression levels are associated with RCC. MicroRNA-124 may be assessed as a biomarker in prognosis and the restoration of miR-124 expression might be effective in the treatment of RCC.

Medial olivocochlear suppression in musicians versus non-musicians.

The medial olivocochlear efferent (MOCE) branch synapses with outer hair cells (OHCs), and the efferent pathway can be activated via a contralateral acoustic stimulus (CAS). The activation of MOCE can change OHC motile responses and convert signals that are capable of controlling the sensitivity of the peripheral hearing system in a frequency-specific manner. The aim of this study was to examine the MOCE system activity in professional musicians using transient evoked otoacoustic emission test and CAS. Musician group showed stronger suppression in all frequency bands in the presence of CAS.

Parvovirus B19 Infection as a Rare Cause of Fulminant Liver Failure: A Case Report.

Parvovirus B19 infection is common in childhood. The clinical presentations range from benign to life threatening. The literature shows that the clinical presentation is influenced by the patient's age and the presence of chronic disease such as chronic hemolytic disorders and immunosuppressed conditions. As the majority of patients with liver failure are diagnosed as indeterminate, knowledge about parvovirus B19 associated liver disease is limited. We examined 3 children with parvovirus B19-induced fulminant liver failure, 2 of whom underwent liver transplantation. Although the presented patients received standard corticosteroid and tacrolimus therapy as an immunosuppressive regimen, acute rejection, parvovirus B19 persistence, or any other complications due to parvovirus B19 were not observed. Physicians should be aware of the parvovirus B19 infection in association to acute liver diseases.

Note: Parameter extraction of samples without the direct application of the passivity principle from reference-plane-invariant measurements.

An extraction algorithm has been proposed for explicit complex permittivity and complex permeability determination of samples using reference-plane-invariant scattering parameters without resorting to the application of the passivity principle. The algorithm relies on the definition of new odd and even reflection coefficients which result in no-crossing of the negative real axis for the argument of the square-root functions. Permittivity measurements of two low-loss samples were performed for validation of our algorithm.

The impact of alternative donor types on viral infections in pediatric hematopoietic stem cell transplantation.

Viral infections remain one of the most important complications following allogeneic HSCT. Few reports compare virus infection between different donor types in pediatric patients. We retrospectively analyzed viral infections and the outcome of one hundred and seventy-one pediatric patients (median 7.38 years) who underwent allogeneic HSCT from matched related donor (MRD, n = 71), 10 of 10 HLA allele-matched unrelated donors (MUD1; n = 29), 9 of 10 HLA allele-matched unrelated donors (MUD2; n = 40), and haploidentical donors (n = 31). PCR screening for BK virus, adenovirus, Epstein-Barr virus, parvovirus B19, human herpesvirus 6, and CMV were performed routinely weekly. Infections between 0-30, 31-100, and 101 days-2 years were identified separately. BK virus and CMV reactivations were significantly low in MRD transplant patients (P = .046 and P < .0001, respectively), but incidences of all virus infections between MUD1, MUD2, and haplo-HSCT were found statistically not different. The OS was found to be affected by having one or multiple virus infection (P = .04 and P = .0008). Despite antiviral prophylaxis and treatments, post-transplant viral infections are associated with reduced overall survival. Haplo-HSCT is comparable with MUD transplantation in the setting of viral infections. A larger study group and prospective studies are needed to confirm this observation.
