Unfolding parental knowledge, attitudes, and beliefs toward palliative care for children with cancer.

BACKGROUND: Parents' views toward pediatric palliative care (PPC) remain underexplored, especially in low/middle-income countries where care relies heavily on families. A better understanding of parents' perspectives would inform strategies to support PPC integration into the care of children with cancer. This multicenter study aimed to examine knowledge, attitudes, and beliefs toward PPC among parents of children with cancer in Lebanon to uncover areas for improvement and determine associated factors. METHODS: Using a quantitative cross-sectional descriptive design, 105 primary caregivers (RR = 95.4%) were recruited during the child's visit to one of three pediatric oncology centers in Lebanon. Data were collected through structured interviews using questionnaire items newly developed or taken from validated tools. Data were analyzed using descriptive statistics, correlational analysis, and multiple linear regression. RESULTS: Only 18/105 participants (17.1%) had heard about PPC and 2% had accurate information about it. When given a brief description, more than 90% endorsed PPC and recommended its integration upon the child's diagnosis. Respectively, "Religious and spiritual engagement" and "Overwhelming negative emotions" were the most cited facilitators and barriers to integrating PPC. Knowledge, attitudes, and beliefs were significantly associated with several demographic and clinical factors such as education level, number of persons living with the child, child's symptom count, and pain score. CONCLUSION: This research is among the very first studies conducted to examine parents' perspectives toward PPC for children with cancer in Lebanon. Study findings inform future directions to promote PPC in limited-resource settings through expanded research, policy, education, and practice initiatives.

Blood Transfusion is Associated With Adverse Outcomes in Pediatric Solid Tumor Oncology Patients Following Tumor Resection.

BACKGROUND: Packed red blood cell (PRBC) transfusion is a lifesaving intervention that also has proinflammatory and immunosuppressive effects. Adults with a malignancy who receive PRBC transfusion have increased rates of infection, tumor recurrence, and decreased survival. The effect of PRBC transfusion among children with solid tumors is unknown. METHODS: We performed a retrospective review of all children who underwent operative resection of a solid tumor malignancy. Data collected included demographic information, location of operation, nadir hemoglobin, and any PRBC transfusion within 30 days of tumor resection. RESULTS: Three hundred sixty children underwent tumor resection at our institution between 2002 and 2013; 194 (54%) received a perioperative blood transfusion. After adjusting for stage at diagnosis, tumor location, preoperative chemotherapy and nadir hemoglobin, blood transfusion was associated with a higher rate of postoperative infectious complications, shorter disease-free interval, and a higher rate of tumor recurrence. Each additional transfused unit increased the risk of postoperative infection (odds ratio 3.83; 95% confidence interval 1.21, 14.22, P =0.031). CONCLUSIONS: Among children with solid tumor malignancies, PRBC transfusion within 30 days of operation is associated with higher rates of postoperative infection. If transfusion becomes necessary, single unit increments should be transfused. LEVEL OF EVIDENCE: Level III.

The effect of an enhanced recovery protocol in pediatric patients who undergo colostomy closure and Malone procedures.

PURPOSE: Pediatric colorectal studies have shown enhanced recovery after surgery (ERAS) protocols can safely improve outcomes. This study sought to determine the impact of an ERAS pathway on the outcomes of children with colorectal conditions who underwent colostomy closure or Malone procedure. METHODS: A single-institution, retrospective cohort study of children who underwent colostomy closure or Malone procedure between 2016 and 2020 was performed. Differences in outcomes between pre-ERAS and ERAS cohorts were tested. A sub-analysis based on procedure type was performed. RESULTS: There were 96 patients included: 22 prior to ERAS implementation and 74 after. Patients who underwent ERAS had shorter mean time (hours) to oral intake, mean days until regular diet, post-operative opioid volume, and median length of stay (p < 0.05). There was no difference in complication rates in the ERAS and pre-ERAS cohort (12.2 vs 9.1%, p = 0.99). Patients who underwent colostomy closure after ERAS had lower post-operative opioid use, but no differences were seen in those who underwent Malone. CONCLUSION: Implementation of an ERAS protocol resulted in quicker time to oral intake, normal diet, and decreased opioid use without increasing complication rates. Differences seen based on procedure type may reflect that the effect of an ERAS protocol is procedure specific.

Pesticide practices in coastal agricultural farms of Lebanon.

The agricultural sector in Lebanon relies heavily on agrochemicals for crop protection; thus exposing humans and the environment to the harmful effects of pesticides. This study investigated Lebanese farmers' pesticide use practices and explored the underlying factors associated with farmers' choices. Of the 104 surveyed farmers, around 87% were willing to use pesticides that are less toxic to humans and the environment than those currently using, if available. The majority of these farmers (92%) planted their crops in greenhouses. Willingness to use less toxic pesticides was significantly associated with farmers using greenhouses as opposed to open fields, after adjusting for demographic and behavioural characteristics (OR = 7.50; p = 0.010). There was no association between willingness to use less toxic pesticides and perceptions of pesticides' health effects. Policies banning the import and sale of internationally banned pesticides must be enforced. Farmers must be supported to make informed choices about pesticides and their use.

Worsening baroreflex sensitivity on progression to type 2 diabetes: localized vs. systemic inflammation and role of antidiabetic therapy.

Cardiac autonomic neuropathy (CAN) is an early cardiovascular manifestation of type 2 diabetes (T2D) that constitutes an independent risk factor for cardiovascular mortality and morbidity. Nevertheless, its underlying pathophysiology remains poorly understood. We recently showed that localized perivascular adipose tissue (PVAT) inflammation underlies the incidence of parasympathetic CAN in prediabetes. Here, we extend our investigation to provide a mechanistic framework for the evolution of autonomic impairment as the metabolic insult worsens. Early metabolic dysfunction was induced in rats fed a mild hypercaloric diet. Two low-dose streptozotocin injections were used to evoke a state of late decompensated T2D. Cardiac autonomic function was assessed by invasive measurement of baroreflex sensitivity using the vasoactive method. Progression into T2D was associated with aggravation of CAN to include both sympathetic and parasympathetic arms. Unlike prediabetic rats, T2D rats showed markers of brainstem neuronal injury and inflammation as well as increased serum levels of IL-1ß. Experiments on PC12 cells differentiated into sympathetic-like neurons demonstrated that brainstem injury observed in T2D rats resulted from exposure to possible proinflammatory mediators in rat serum rather than a direct effect of the altered metabolic profile. CAN and the associated cardiovascular damage in T2D only responded to combined treatment with insulin to manage hyperglycemia in addition to a nonhypoglycemic dose of metformin or pioglitazone providing an anti-inflammatory effect, coincident with the effect of these combinations on serum IL-1ß. Our present results indicate that CAN worsening upon progression to T2D involves brainstem inflammatory changes likely triggered by systemic inflammation.

Cardiac Autonomic Neuropathy: A Progressive Consequence of Chronic Low-Grade Inflammation in Type 2 Diabetes and Related Metabolic Disorders.

Cardiac autonomic neuropathy (CAN) is one of the earliest complications of type 2 diabetes (T2D), presenting a silent cause of cardiovascular morbidity and mortality. Recent research relates the pathogenesis of cardiovascular disease in T2D to an ensuing chronic, low-grade proinflammatory and pro-oxidative environment, being the hallmark of the metabolic syndrome. Metabolic inflammation emerges as adipose tissue inflammatory changes extending systemically, on the advent of hyperglycemia, to reach central regions of the brain. In light of changes in glucose and insulin homeostasis, dysbiosis or alteration of the gut microbiome (GM) emerges, further contributing to inflammatory processes through increased gut and blood-brain barrier permeability. Interestingly, studies reveal that the determinants of oxidative stress and inflammation progression exist at the crossroad of CAN manifestations, dictating their evolution along the natural course of T2D development. Indeed, sympathetic and parasympathetic deterioration was shown to correlate with markers of adipose, vascular, and systemic inflammation. Additionally, evidence points out that dysbiosis could promote a sympatho-excitatory state through differentially affecting the secretion of hormones and neuromodulators, such as norepinephrine, serotonin, and γ-aminobutyric acid, and acting along the renin-angiotensin-aldosterone axis. Emerging neuronal inflammation and concomitant autophagic defects in brainstem nuclei were described as possible underlying mechanisms of CAN in experimental models of metabolic syndrome and T2D. Drugs with anti-inflammatory characteristics provide potential avenues for targeting pathways involved in CAN initiation and progression. The aim of this review is to delineate the etiology of CAN in the context of a metabolic disorder characterized by elevated oxidative and inflammatory load.

Decentralization of solid waste management services in rural Lebanon: Barriers and opportunities.

Rapid urbanization, closure of dumps, and insufficient infrastructure funding in Lebanon have resulted in improper municipal solid waste management (MSWM), creating a continuing trash crisis in recent years. In Beirut and Mount Lebanon, MSWM was carried out in centralized waste processing and disposal facilities operated by the government. The trash crisis and failure of the centralized system prompted several municipal authorities to decentralize MSWM by establishing local facilities, paid by the council taxes charged to beneficiary households. To study the feasibility of decentralized MSWM, a survey of 228 households in a rural village in Lebanon explored households' willingness to pay (WTP) for a local MSWM service. For data analysis, a multivariate Tobit model was used to examine the determinants of the WTP amount. Results showed that 79% of surveyed households in the studied village were willing to support local MSWM improvements by contributing an average yearly fee of US$48, representing a 30% increase in their current council taxes. Analysis showed a significant positive association between the WTP amount and the household monthly income level, the residents perceived needs for urgency to act on solid waste management, and the households' responsibility to be involved in MSWM. An interview with the municipality mayor later revealed that financial, technical, and land resources are lacking to enable consideration of a decentralized project for MSWM in the village. Municipalities in rural areas have limited resources and are unable to sustain a decentralized MSWM service unless adjacent towns join effort in supporting and financing MSWM initiatives.

The relationship between work-related musculoskeletal disorders, chronic occupational fatigue, and work organization: A multi-hospital cross-sectional study.

AIMS: To identify the prevalence of work-related musculoskeletal disorders, levels of chronic occupational fatigue, and how they vary with individual and work organization factors. DESIGN: A multi-hospital cross-sectional survey. METHODS: Nurses from 39 hospitals completed self-reported questionnaires from June to September 2015. Descriptive statistics were used to summarize hospitals and nurses' characteristics, fatigue levels and prevalence, and type of musculoskeletal disorders. Linear and logistic regression analyses were used to identify correlational factors. RESULTS: The results revealed that 71.3% of participants reported a work-related musculoskeletal disorder in the previous 12 months, mainly back pain. The reported musculoskeletal disorders were significantly correlated with years of experience, nurse to patient ratios, and chronic occupational fatigue. Higher chronic occupational fatigue levels were associated with education, age, years of experience, nurse to patient ratio, and model of care. CONCLUSION: Preventive work organization strategies are needed to ensure healthier occupational environment for nurses.

Symptom prevalence and management in older adult patients in Lebanon.

OBJECTIVE: The purpose of this study is to explore symptoms and the effectiveness of their management in older adult palliative care candidates in Lebanon. The aims of this study were to: (1) determine symptom prevalence in Lebanese older adults who qualify for palliative care; (2) identify the severity and distress of symptoms; (3) identify the prevalence of symptom management and its efficacy; and (4) explore the relationship between overall symptom burden and its correlates. METHOD: This study uses an observational cross-sectional design using convenience sampling (N = 203) to recruit older adults qualifying for palliative care from three major medical centers in Lebanon. RESULT: The mean age of the sample was 78.61 years. The most prevalent symptoms were lack of energy (93.5%), worrying (83.2%), and pain (71.4%). Psychological symptoms had the highest mean scores, preceded only by the physical symptoms and lack of energy. The most treated symptoms were physical with pain having the highest treatment prevalence (91%). Although psychological symptoms were the most burdensome, they were poorly treated. Multiple regression analysis showed that symptom scores had significant positive associations with financial status, social functioning, and comorbidities; there was a negative association with age. SIGNIFICANCE OF RESULTS: Lack of energy and psychological symptoms were the most prevalent, with the latter having the highest mean total symptom scores. Treatment was poor for psychological symptoms and effective for physical ones. Associations were found between age, comorbidity, financial problems, social functioning, and total physical and psychological mean symptom burden scores. More attention needs to be given to psychological symptoms and their management among older adults receiving palliative care.

Correction to: PTSD and gender: could gender differences in war trauma types, symptom clusters and risk factors predict gender differences in PTSD prevalence?

AbstractThe female-male ratio in the prevalence of post-traumatic stress disorder (PTSD) is approximately 2:1. Gender differences in experienced trauma types, PTSD symptom clusters, and PTSD risk factors are unclear. We aimed to address this gap using a cross-sectional design. A sample of 991 civilians (522 women, 469 men) from South Lebanon was randomly selected in 2007, after the 2006 war. Trauma types were grouped into disaster and accident, loss, chronic disease, non-malignant disease, and violence. PTSD symptom clusters involved re-experiencing, avoidance, negative cognitions and mood, and arousal. These were assessed using parts I and IVof the Arabic version of the Harvard Trauma Questionnaire (HTQ). Risk factors were assessed using data from a social support and life events questionnaire in multiple regression models. Females were twice as likely as males to score above PTSD threshold (24.3 vs. 10.4%, p ˂ 0.001). Total scores on all trauma types were similar across genders. Females scored higher on all symptom clusters (p < 0.001). Social support, social life events, witnessed traumas, and domestic violence significantly were associated with PTSD in both genders. Social support, social life events, witnessed traumas and domestic violence were significantly associated with PTSD in both genders. Conversely, gender difference in experienced traumas was not statistically significant. These findings accentuate the need to re-consider the role of gender in the assessment and treatment of PTSD.

The first Arabic version of the Actual Scope of Nursing Practice Scale: Psychometric evaluation.

AIM: We examined the validity and reliability of nursing activity levels of complexity in the first Arabic version of the Actual Scope of Nursing Practice Questionnaire. BACKGROUND: Nurse executives need valid and reliable data on the scope and complexity of nursing practice to make decisions about cost-effective and safe deployment of the nursing workforce. We translated the English version of the Actual Scope of Nursing Practice Questionnaire into Arabic for use in Lebanon and the eastern Mediterranean region. METHODS: Data were collected from a national sample of bedside nurses in Lebanon in which 3,157 questionnaires were returned for analysis. We used multidimensional scaling, hierarchical cluster analysis, and confirmatory factor analysis to examine the Arabic Actual Scope of Nursing Practice Questionnaire levels of nursing complexity. RESULTS: Multidimensional scaling analysis and hierarchical cluster analysis confirmed the unidimensionality of the Arabic Actual Scope of Nursing Practice Questionnaire. Confirmatory factor analysis produced essentially the same fit statistics for the unidimensional model and three-dimensional models of item complexity. CONCLUSION: The Arabic Actual Scope of Nursing Practice Questionnaire is a valid and reliable unidimensional measure of nursing complexity. IMPLICATION FOR NURSING MANAGEMENT: Nurse executives and hospital managers in Lebanon and the eastern Mediterranean region can use total and mean Arabic Actual Scope of Nursing Practice Questionnaire scores as aids when making decisions about nursing workforce deployment.

Bisphenol A exposure assessment from olive oil consumption.

The use of bisphenol A (BPA) in packaging has grown over the past 50 years despite concerns of its migration into packaged food and beverages, resulting in human exposure. Many studies have reported tumorigenic effects and endocrine alterations associated with BPA in animal models. This study aims at assessing human exposure to BPA from olive oil. A total of 27 olive oil samples were collected from mills and local villagers in the Hasbaya District, a major olive oil harvesting region in Lebanon. Information on storage conditions was also collected. BPA was extracted and quantified by HPLC. Results showed significantly higher BPA levels in olive oil samples stored in plastic vs. non-plastic packaging (mean = 333 vs. 150 µg/kg, p value = 0.006), samples with a plastic storage duration of >1 year compared to those with a storage duration of <1 year (mean = 452 vs. 288 µg/kg, p value = 0.008), and oil samples sourced from locals compared to oil mills (mean = 376 vs. 228 µg/kg, p value = 0.022). Statistically significant higher BPA levels remained for samples stored in plastic vs. non-plastic packaging in the bootstrap multivariable linear regression (B = 121.56, 95% CI 53.44-194.39, p value = 0.009). This is the first report on BPA levels in Mediterranean olive oil. The estimated exposure was 1.38% of the EFSA tolerable daily intake, hence there are no concerns about potential health risks from olive oil consumption.

Psychometric validation of the Arabic multiple sclerosis resiliency scale: Uncovering resilience factors in Lebanese MS patients for clinical and research advancements.

Background: Multiple sclerosis (MS) is an autoimmune demyelinating disease that involves the central nervous system (CNS). Individuals with Multiple Sclerosis (MS) may experience difficulty adapting to their diagnosis as the unpredictable nature of the disease can be challenging to cope with. Methods: The purpose of this study is twofold. First, we have culturally adapted and analyzed the Arabic version of the Multiple Sclerosis Resiliency Scale (MSRS) psychometric properties. Second, we aimed to explore resilience in a sample of Lebanese patients with MS in the face of the chronic disease and financial hardship that Lebanon is going through to evaluate their strengths and struggles. The sample consisted of 306 participants aged between 18 and 79 diagnosed with MS for at least one year. Results: After examining criterion validity, construct validity, internal consistency, and test-retest reliability, the Arabic version of the MSRS exhibited good psychometric properties. The study also revealed that resilience increases with age and lower disability scores. Additionally, individuals with higher resilience levels displayed lower levels of depression. The research revealed that MS patients have high resilience, mainly relying on cognitive and emotional strategies, social support from family and friends, MS peer support, and spirituality. Conclusion: These findings highlight the importance of emotional coping strategies and social support in building resilience among MS patients.

Surgical duration of cochlear implantation in an academic university-based practice.

OBJECTIVE: Establish the time to safely and efficiently perform cochlear implantation (CI) in a university-based academic center. STUDY DESIGN: Case series with chart review. SETTING: Academic neurotologic referral center. PATIENTS: 424 patients who underwent CI surgery between 2002 and 2010. INTERVENTION: Unilateral, bilateral or revision CI using commercially available devices approved for use in the United States. MAIN OUTCOME MEASURES: mean surgical duration (SD) and mean total operative room time (TORT). RESULTS: Overall mean SD for all 424 patients was 83 ± 30 min (min) whereas the mean TORT was 135 ± 56 min. The mean SD for unilateral CI was 84 ± 18 min for the first implant and 82 ± 22 min for the second implant (p=0.55). The SD for primary and revision CI was 83 ± 18 min and 85 ± 36 min, respectively (p=0.51). The mean SD for pediatric and adult CI was 83 ± 21 min and 83 ± 18 min, respectively (p=0.92). The mean SD without resident assistance was 74 ± 14 min whereas with the assistance of a resident the mean SD was 84 ± 20 min (p=0.02). When ossification was encountered the mean SD was 90 ± 32 min compared to 82 ± 19 min when absent (p<0.001). An association was found between TORT or SD, and the year of surgery, presence of ossification and the involvement of an assistant. CONCLUSION: In a university-based academic center, CI surgery can be safely and efficiently performed, supporting future cost-effectiveness analysis of its current practice.

Predictors of quality of life in older adult patients in Lebanon: a cross sectional study.

BACKGROUND: The older adult population in Lebanon is anticipated to double by year 2030. The health care resources available for the geriatric population is limited and there is much reliance on the social support of family caregivers. Older adults have double the rate of hospital utilization in comparison to the regular Lebanese population where 4.5% are hospitalized more than once per year. This study aims to describe self-reported quality of life (QoL) among hospitalized patients "with palliative care needs" and investigate the relationship with its four health domains. METHODS: An observational survey design with a convenience sample of 203 hospitalized patients with palliative care needs above 65 years of age were recruited from three hospitals. Descriptive statistics and regression analysis were used to describe and determine the association between health domains and QoL. RESULTS: Mean age of participants was 78.5 years with the majority being male and married. Participants reported low overall QoL with a mean score of 35.43 (SD =23.45). Anxiety and depression were common findings. "Worrying" (83%), "Feeling nervous" (80%), "Feeling sad" (76%) were dominant psychological symptoms. Low scores were also observed for physical, role and social functioning. Participants suffered from lack of energy (94%), pain (72%), difficulty sleeping (73%) and shortness of breath (64%). CONCLUSIONS: The findings suggest that QoL in the aging Lebanese population is burdened with physical and psychological symptoms. A comprehensive approach that attends to the psychosocial as well as the physical problems in older adults with early integration of symptom management and palliation could improve QoL.

Risk of thromboembolic events in non-hospitalized COVID-19 patients: A systematic review.

The risk of thromboembolism in non-hospitalized COVID-19 patients remains uncertain and was assessed in this review to better weigh benefits vs. risks of prophylactic anticoagulation in this population. A search was performed through three databases: Medline, Embase, and Cochrane Library until 2022. Self-controlled case series, case-control and cohort studies were included, and findings summarized narratively. Meta-analyses for risk of thromboembolism including deep vein thrombosis (DVT), pulmonary embolism (PE), and myocardial infarction (MI) between COVID-19 and non-COVID-19 non-hospitalized patients were conducted. Frequency, incidence rate ratio (IRR), and risk ratio (RR) of stroke were used to assess risk in non-hospitalized COVID-19 patients considering the lack of studies to conduct a meta-analysis. Ten studies met inclusion criteria characterized by adult non-hospitalized COVID-19 patients. Risk of bias was relatively low. Risk of DVT (RR: 1.98 with 95% CI: 1.03-3.83) and PE (OR: 6.72 with 95% CI: 4.81-9.39 and RR: 4.44 with 95% CI: 1.98-9.99) increased in non-hospitalized COVID-19 patients compared to controls. Risk of MI (OR: 1.91 with 95% CI: 0.89-4.09) is possibly increased in non-hospitalized COVID-19 patients with moderate certainty when compared to controls. A trend in favor of stroke was documented in the first week following infection. Our meta-analyses support the increase in risk of DVT and PE, and likely increase of MI, in non-hospitalized COVID-19 patients. The risk of stroke appears significant in the first week following infection but drops to insignificance two weeks later. More studies are needed to establish evidence-based recommendations for prophylactic anticoagulation therapy in non-hospitalized COVID-19 patients.

Assessing the outcomes of prescribing angiotensin converting enzyme inhibitors and angiotensin receptor blockers for COVID-19 patients.

Background: Patients with heart failure were affected severely by COVID-19. Most heart failure patients are on guideline directed medical therapy, which includes ACE inhibitors (ACEI) and ARBs. These medications were controversial at the beginning of the pandemic due to their interplay with the receptor that SARS-CoV-2 binds in the lungs. We investigated the effect that ACEI and ARB had on patients with hypertension, coronary artery disease, and heart failure. Methods: We recruited 176 patients with COVID-19 infection and cardiovascular comorbidities at the American University of Beirut Medical Center in Lebanon. Of these, 110 patients were taking ACEI or ARB and 66 were not. We collected clinical data and looked at inflammatory markers such as CRP and IL-6 and cardiac markers such as troponin T. We also reported the incidence of ARDS, sepsis, and death of each patient, and compared the 2 groups. Results: We found that patients taking ACEI and ARB had a statistically significant decrease in levels of troponin T, IL-6, and CRP compared to patients not taking these medications (p < 0.05). We found no difference in rates of ARDS, sepsis, or death between the 2 groups. Conclusion: Inhibition of the renin-angiotensin-aldosterone-system had no effect on the mortality of patients with COVID-19 and on their overall disease progression. However, it may be beneficial not to stop these medications as they decrease inflammation in the body and the levels of troponin, which are related to increased stress on the heart.

Cochlear implantation outcomes in patients with far advanced otosclerosis.

OBJECTIVES: To compare hearing outcomes in patients with far advanced otosclerosis (FAO) undergoing cochlear implantation to an age-matched group of controls, to describe the effects of cochlear ossification on hearing, and to review the adverse effects of implantation in patients with FAO. HYPOTHESIS: Hearing performance in patients with FAO after cochlear implantation is comparable to similarly treated postlingually deafened adults without FAO. Ossification or retrofenestral otosclerosis does not predict poor hearing outcomes. Modiolar-hugging technology reduces postoperative facial nerve stimulation. STUDY DESIGN: Retrospective chart review. SETTING: Academic neurotologic tertiary referral center. PATIENTS: Thirty patients with FAO, who metaudiological criteria for cochlear implantation, were compared to 30 age-matched controls, postlingually deafened by non-otosclerotic causes. MAIN OUTCOME MEASURES: Audiometric pre- and postoperative speech reception threshold, word, and sentence scores were analyzed. The presence of retrofenestral findings on computed tomography or intraoperative cochlear ossification were noted. RESULTS: In the FAO group, radiographic abnormalities were noted in 26.4% of patients. Intraoperative ossification requiring drillout was seen in 29.4% of patients. None developed postoperative facial nerve stimulation. There was no difference between the FAO and control groups in the mean short-term and long-term postoperative speech reception threshold, word, and sentence scores (P = .77). The presence of radiographic abnormalities did not predict hearing outcome. Intraoperative cochlear ossification was not associated with worse short-term word and sentence scores (P = .58 and 0.79, respectively), and for the long-term hearing outcome (P = .24). CONCLUSIONS: In patients with FAO, effective and safe hearing rehabilitation can be accomplished with cochlear implantation.
