Saudi Population Nasal Anthropometric Study: Local and International Comparison.

Anthropometric measurements are essential for diagnosing and treating various craniofacial disorders during nasal reconstruction and esthetic surgery. Different people have unique individual esthetic features that are a mixture of different races and backgrounds. This study aimed to compare 12 different anthropometric measurements in the Saudi Arabian population with those in other local and international studies. This cross-sectional study was conducted with 420 volunteers from December 2022 to August 2023 in Riyadh, Saudi Arabia. Study samples were drawn from the general population, and 12 nasal anthropometric variables were measured, including 7 linear and 5 angular variables, by taking digital photographs from frontal and lateral views. Anthropometric landmarks and measurements were obtained as previously described by Farkas et al. Photographs were analyzed using Adobe Photoshop CS4 software, and facial landmarks were identified. Data were analyzed using an independent sample t test to assess the mean and SD with differences (P<0.05 indicated a significant value). After statistical analysis, the results were compared with previously published standards for other races. Exactly 420 Saudi Arabian volunteers were examined to compare nasal anthropometric variables. All 12 nasal anthropometric variables differed significantly between male and female individuals. Anthropometry of the nose has an enormous miscellaneous relationship between sexes and populations of different geographic areas. It is important to create average anthropometric measurements for different groups for successful plastic surgery and rhinoplasty.

The Impact of the COVID-19 Pandemic on Diabetes Self-Management in Saudi Arabia.

The COVID-19 pandemic disrupted healthcare worldwide, potentially impacting disease management. The objective of this study was to assess the self-management behaviors of Saudi patients with diabetes during and after the COVID pandemic period using the Arabic version of the Diabetes Self-Management Questionnaire (DSMQ). A cross-sectional study was conducted in patients aged ≥18 years diagnosed with type 2 diabetes mellitus who had at least one ambulatory clinic visit in each of the specified time frames (Pre-COVID-19: 1 January 2019-21 March 2020; COVID-19 Time frame: 22 March 2020 to 30 April 2021) utilizing the DSMQ questionnaire, with an additional three questions specifically related to their diabetes care during the COVID pandemic. A total of 341 patients participated in the study. The study results revealed that the surveyed patients showed moderately high self-care activities post-COVID-19. Total DSMQ scores were significantly higher in patients aged >60 years versus younger groups (p < 0.05). Scores were significantly lower in patients diagnosed for 1-5 years versus longer durations (p < 0.05). Patients on insulin had higher glucose management sub-scores than oral medication users (p < 0.05). Overall, DSMQ scores were higher than the pre-pandemic Saudi population and Turkish post-pandemic findings. DSMQ results suggest that, while COVID-19 negatively impacted some self-management domains, the Saudi patients surveyed in this study upheld relatively good diabetes control during the pandemic. Further research is warranted on specific barriers to optimize diabetes care during public health crises.

A population-based study of 15,000 people on Knowledge and awareness of lung cancer symptoms and risk factors in Saudi Arabia.

Lung cancer is currently the most fatal form of cancer worldwide, ranking as the fourth most prevalent type in Saudi Arabia, particularly among males. This trend is expected to increase with growing population, lifestyle changes, and aging population. Understanding the awareness of the Saudi population regarding the risk factors and symptoms of lung cancer is necessary to attenuate the predicted increase in cases. A cross-sectional, population-based survey was performed using a previously validated questionnaire (Lung CAM). Multiple linear regression analysis was used to assess variables associated with deficiency in knowledge and awareness of risk factors and symptoms of lung cancer. Majority of the 15,099 respondents were male (65%), aged between 18 and 30 years (53%), 50% of which were educated up to a bachelor's degree level. Overall awareness of lung cancer signs and symptoms was 53%, with painful cough and coughing up blood being the best-known symptoms. Conversely, persistent shoulder pain (44%) and clubbing fingers (47%) were the least known lung cancer symptoms. Also, 60% of the respondents showed low confidence in identifying the signs and symptoms of lung cancer. The overall awareness of the risk factors for lung cancer development was 74%, with first-hand (74%) and second-hand (68%) smoking being the most known risk factors. However, only ≤ 62% know the other non-smoking risk factors. Awareness of the risk factors and symptoms of lung cancer depended on age, gender, education, marital and employment status (p < 0.001). Public awareness of the risk factors and symptoms of lung cancer in Saudi Arabia is inadequate and heavily dependent on education and socio-economic status. Awareness can be improved through campaigns to raise awareness about other lesser-known lung cancer risk factors and symptoms.

Parental Knowledge Toward Meningococcal Disease and Vaccination in Makkah Region, Saudi Arabia: A Cross-Sectional Study.

Background Invasive meningococcal disease (IMD) is a bacterial infection caused by Neisseria meningitidis, which primarily affects the meninges, with a high incidence in young children. The most effective technique for preventing IMD is vaccination, which has been available for over 40 years through meningococcal polysaccharide capsule-containing vaccines. This study aims to assess the parental knowledge of meningococcal disease and vaccination in the Makkah region of Saudi Arabia. Methodology A cross-sectional study was conducted between September and December 2023 among597 parents in the Makkah region using a validated online survey. The collected data were analyzed using the Statistical Package for the Social Sciences (SPSS). Results The study sample included 597 parents, of which 339 (56.8%) were female and 258 (43.2%) were male. Our research demonstrated that 388 (65%) participants had an insufficient understanding of IMD, while209 (35%) had a sufficient understanding. There was a significant correlation between the knowledge score and the completion of the routine vaccination and whether vaccinating a child is essential for the protection of other members of society. Conclusions Based on our study, only around one-third of the participants demonstrated a sufficient level of knowledge regarding IMD and its vaccination. To provide a more accurate assessment of the Saudi population, additional research should be conducted in various regions and cities.

The Use of Electronic Cigarettes in Saudi Arabia: A Narrative Review.

The use of electronic cigarettes (or "e-cigarettes") is spreading throughout the world. Population-level data from a number of countries indicate that e-cigarettes are used more by children and young adults than by the overall population. Although extensive research has been conducted in Western nations to better understand many aspects of e-cigarette usage among children and young adults, Middle Eastern nations have little data on this topic. The use of tobacco is detrimental to the health, finances, and national spirit of Saudi Arabia. More than 7,000 of its citizens die each year from diseases caused by tobacco use. Nevertheless, more than 20,000 youngsters and 3,352,000 adults smoke cigarettes each day. Similarly, the use of electronic cigarettes is on the rise, possibly as a result of aggressive publicity and marketing campaigns by manufacturers that appeal to the younger demographic. This review was undertaken through literature research to ascertain the usage and attitudes toward e-cigarette use among the Saudi population.

Saudi Healthcare Students' General Practices Applied to Protect Against COVID-19 and Their Beliefs Regarding the Use of Herbal Supplements as a Protection Method.

At the beginning of the COVID-19 pandemic, the absence of treatment increased the Saudi population's inquietude regarding the virus. Therefore, people were seeking alternative methods to protect themselves from disease's fast transmission, such as hand hygiene, social isolation, and the use of natural and dietary products. The main objective of this study is to assess healthcare students' general practices applied to protect against COVID-19 and their beliefs regarding the use of herbal supplements as a protection method. All undergraduate healthcare students were eligible to participate, except pre-professional students. The estimated sample size was 371, which was calculated using Raosoft® software (Raosoft Inc.,Seattle, WA). A cross-sectional online survey was distributed among the targeted population. The data were entered in Microsoft Excel (Microsoft Corporation, Redmond, WA) and transferred to be analyzed by JMP software (SAS Institute Inc., Cary, NC). A total of 441 healthcare students, who met the inclusion criteria, participated in this study. About 81.41% of the participants reported that they were completely committed to Saudi guidelines regarding preventive measures against COVID-19 transmission. Most of the participants were not using herbal supplements, while 17.1% of them used herbal products or dietary supplements during the COVID-19 pandemic. The participants who used herbal and dietary products commonly consumed ginger and vitamins C and D. In addition, a chi-square showed significant differences in gender and specialties regarding the usage of herbal supplements as a protective method against COVID-19 (P<0.05). The findings of our study exhibit the general practice of herbal products during the COVID-19 pandemic among Saudi healthcare students was low in comparison withtheir beliefs. In addition, the using of herbal supplements should be evidence-based to guarantee safe consumption.

Usage, knowledge and perception of the ketogenic diet and associated factors in Saudi adults: A cross-sectional study.

The ketogenic diet (KD) is a popular weight management method. However, knowledge, perceptions, and use of KD have not been studied in the Saudi population. This cross-sectional study aims to assess the knowledge, perceptions, and use of the KD in Saudi Arabia, to compare medical and nonmedical students in their awareness of KD, and to determine factors associated with knowledge and perception of KD. A total of 1071 Saudis aged ≥ 18 years old were included. Participants were excluded if they were younger than 18, non-Saudi, pregnant, breastfeeding, had chronic illnesses, were using any medication, or were diagnosed with psychiatric conditions. Knowledge, perception, and use of KD were collected between 2021 and 2022 in Saudi Arabia using a prevalidated tool and its scoring protocol; higher scores indicated higher level of knowledge or perception. Among Saudi adults, 24% (n = 253) and 55% of them (n = 138/253) followed the KD for 1 month or less, respectively. The KD knowledge score was mean ± SD: 7.95 ± 3.97 and half of the participants (49.5%) had a low knowledge level. Students had a significantly lower knowledge score (mean ± SD: 7.69 ± 3.85) compared to nonstudents (mean ± SD: 8.68 ± 4.19). Students in medical majors had a higher knowledge score compared to nonmedical major students (P < .001). The KD perception score was mean ± SD: 28.74 ± 4.83 and 76% of the participants had moderate perception level. Males had a significantly higher perception score compared to females (P < .001). Students in medical majors had a lower perception score compared to nonmedical major students. Age and body mass index had a significantly weak positive correlation with knowledge and perception scores. Half of the sample had low knowledge and moderate level of perception about KD. Students with medical majors had higher knowledge but lower perception scores compared to nonmedical majors. Dieticians may measure the knowledge and perception of the KD diet in outpatient clinics to lose weight. Educational institutions may increase students' knowledge and perception of the KD in all majors. Future experimental studies examining the efficacy of the KD are needed to provide recommendations of the KD as a strategy for weight loss.

Incidence and characteristics of developmental dysplasia of the hip in a Saudi population: A comprehensive retrospective analysis.

Developmental dysplasia of the hip (DDH) is a common hip disorder in infants. Ultrasonographic screening is considered the most reliable method for early detection of DDH in newborn infants. This study aimed to determine the incidence of DDH at King Abdulaziz University Hospital. From January 2017 to December 2018, this retrospective study analyzed the data of 8031 infants who underwent an early clinical examination of the hips. At the initial evaluation, 212 infants referred to the ultrasound department had risk factors for DDH and/or clinical instability. Different well-known risk factors of DDH have been identified including breech position, skeletal deformities, positive family history, hip side, sex and clicky hip. The findings revealed an incidence rate of 93 cases of DDH among 8031 infants (11.58 per 1000) births. Among the infants diagnosed with DDH, 55 were females (59.14 %), and 38 were males (40.86%). The results of the current study revealed that 45% of infants with DDH exhibited bilateral involvement. Moreover, results showed that the IIa hip joint was more prevalent in female than in male newborns, but without any significant difference. The incidence rate of DDH in this study was 11.58 per 1000 live births, and it was more prevalent among female than male newborns. Ultrasonography (US) should be used as a complementary imaging modality for clinical examination of DDH. Infants with breech presentation, clicky hip, and skeletal deformity should be scanned by US. Further prospective studies are recommended.

Assessing suboptimal health status in the Saudi population: Translation and validation of the SHSQ-25 questionnaire.

Suboptimal Health Status (SHS) is realised as a vital feature for improving global health. However, the Arabian world does not have a validated instrument for screening SHS in their population. Therefore, the study aimed to evaluate the psychometric properties of Arabic-translated SHS (ASHSQ-25) in the Saudi Arabian population. We conducted a cross-sectional study among the conveniently sampled 1590 participants from the Saudi population (with a 97.4% response rate). The data was gathered through an online survey and then exported into SPSS and AMOS version 26.0 for analysis. Mann-Whitney and Kruskal-Wallis tests were used to identify the median difference between demographic groups. The one-tailed 90% upper limit of SHS scores was chosen as the cut-off criteria for SHS. Reliability and confirmatory analysis were performed for the psychometric evaluation of ASHSQ-25 in the Saudi Arabian context. This study demonstrates that the ASHSQ-25 has good internal consistency, interclass correlation coefficient (ICC) = 0.92; 95% confidence interval (CI) = 0.91-0.93) and reliability (Cronbach's α = 0.92). The confirmatory factor analysis (CFA) results indicated a good fit of the databased on the CMIN/degrees of freedom (df) = 4.461, comparative fit index (CFI) = 0.94, Tucker Lewis index (TLI) = 0.93, and Root Mean Square Error of Approximation (RMSEA) = 0.05. The result factor loadings for each item were high (≥ 0.55), except for one item from the immune system subscale. The SHS cut-off point for ASHSQ-25 was 33, leading to a 23.7% prevalence of SHS. This study reveals that ASHSQ-25 has appropriate internal consistency and structural validity to assess SHS in an Arabic-speaking population; therefore, it is recommended.

Exploring Mental Health Literacy and Its Associated Factors: A National Cross-Sectional Study in Saudi Arabia, 2023.

The aim of this study is to examine, for the first time, the mental health literacy of the Saudi general population. Additionally, we aim to identify demographic factors associated with elevated mental health literacy scores. A cross-sectional study using a phone interview survey with quota sampling was conducted for equal distribution of sexes, age and administrative regions. Mental health literacy was assessed by the previously validated mental health literacy scale (MHLS). The MHLS ranges from 35 to 160, and a higher score indicates greater level of mental health literacy. In this study, 4,547 (70.2%) agreed to complete the interview. The sample was equally distributed across Saudi Arabia's 13 administrative regions with 50.1% female and mean age 35.9 (SD: ±12.8). In terms of education, 55.1% have a bachelor's degree or above. The nationally weighted score on the original MHLS was 110.75. the MHLS Saudi validation score was influenced by various variables including: marital status, healthcare-related job, sex, education level, and proximity to individuals with mental health issues. The study offers data for the first time on Saudi Arabian mental health literacy status. The high MHLS score reflects good societal awareness and understanding of mental health related concepts and issues in the Saudi population. The results of this study set the baseline for mental health literacy in Saudi Arabia. Future research may focus on utilizing the validated MHLS and the method used in this study to explore the effect of other social and individual factors on mental health literacy.

Adverse Impact of Systemic Lupus Erythematosus on Pregnancy Outcomes: A Saudi Arabia Retrospective Multi-Center Study.

The current study aimed to determine the pregnancy outcomes complications in patients with SLE and its association with clinical, laboratory variables, disease activity, and medication use in the Saudi population, as well as pregnancy effect on disease activity. A multicenter study included pregnant female patients with Systemic Lupus Erythematosus (SLE) from three tertiary centers in Saudi Arabia. The demographics, clinical, and laboratory variables, SLE disease activity index (SLEDAI), medication before, during, and after pregnancy, planned pregnancy, pregnancy-related outcomes, and complications in comparison to age-matched healthy female controls were noted. A total of 66 pregnant patients with SLE and 93 healthy age-matched pregnant controls were included in the study. A total of 77.3% had SLEDAI-2K ≤ 4 before conception, and 84.85% of pregnancies were planned. Age of conception, cesarean section, miscarriage, and low birth weight were statistically significant (p <0.05) higher in SLE patients than in healthy controls. Among all clinical and laboratory variables, SLEDAI-2K > 4 and active lupus nephritis during pregnancy were statistically associated with adverse outcomes (p <0.05), history of lupus nephritis was not associated with statistically adverse pregnancy outcomes. Higher SLEDAI-2K > 4 was an independent risk at least 4.87 times higher association with adverse pregnancy outcomes. (p <0.05). SLE is intricately connected with unfavorable pregnancy outcomes. The preconception of high disease activity stands as a pivotal risk factor for adverse outcomes. Despite the disease remission and meticulous planning, SLE patients frequently grapple with disease exacerbations during pregnancy, culminating in unexpected and unfavorable pregnancy-related outcomes. This underscores the intricate and multifaceted nature of managing SLE during gestation.

Short-Term and Long-Term Impact of COVID-19 on Quality of Life and Psychological Outcomes in Saudi Arabia: A Comparative Cross-Sectional Study.

Prior research has revealed notable declines in health-related quality of life (HRQoL) and substantial psychological impacts among individuals infected with COVID-19. However, there is a noticeable gap in studies addressing the enduring long-term effects of COVID-19 on HRQoL and psychological well-being. The current study investigated and compared short and long-term effects of COVID-19 on HRQoL and psychological outcomes among the Saudi population. The Arabic version of the SF-36 questionnaire was used to assess HRQoL while Anxiety and depression were evaluated by the Hamilton Anxiety (HAM-A) and Depression Scales (HDRS). Participants (n=292) were categorized into three groups: the "never-been-infected" group (n=134), the "one-year infected group" (n=43), and the "more than one year infected" group (n=115). Descriptive statistics were presented using numerical values and frequencies. To compare the groups, a one-way analysis of variance (ANOVA) test was used. Most SF-36 domains exhibited lower values while HAM-A and HDRS values were higher in individuals infected during last year compared to those who never infected. Social functioning subscale of the SF-36 showed a significant difference between the groups (F (2.289) = 6.094, p = 0.01) and the effect size was d = 0.95. Pairwise comparison showed a significant reduction in the social functioning component of SF-36 in "one-year group" compared to both groups "never-been-infected" group (mean difference -13.58 (4.40-22.76) p < 0.01) and "more than one year infected" group (mean difference -10.80 (1.44-20.16) p = 0.02). HAM-A and HDRS scores showed mild levels of anxiety (<17 score) and depression (8 to 16 score) in all groups. The influence of COVID-19 on psychological well-being and HRQoL is significant regardless of whether individuals infected with the virus. Overall, the consistent presence of mild anxiety and depression across all groups highlights the need for a holistic approach to mental health.

Assessment of lifestyle changes related to quarantine among Saudi population during the early COVID-19 pandemic: pre- and post-analysis

BackgroundThe escalating emergence of the COVID-19 pandemic interrupted human life due to the ever-increasing morbidity, containment measures, and the associated emotional distress. This study examined the influence of COVID-19-related measures on the lifestyle behaviors of adults living in the Kingdom of Saudi Arabia (KSA).MethodsThe study recruited 638 participants through convenience sampling in Jeddah and Taif cities, Saudi Arabia. Demographic characteristics and COVID-19-related information were collected through an anonymous self-reported electronic questionnaire. Lifestyle behaviors were assessed before and during the quarantine using the Healthy Dietary Habits Index (HDHI)-A and the International Physical Activity Questionnaire (IPAQ-SF).ResultsThe study revealed significant changes in the dietary pattern: a reduction in fish intake and increased consumption of French fries and candies. Vegetables and fruit intake increased significantly. Sedentary time > 6 h per day increased from 36.7% pre to 60.8% during the pandemic. Healthy dietary index score and physical activity MET-minutes/week values were respectively 3.5% and 37.9% significantly higher before compared to the full quarantine period.ConclusionThe pandemic detrimentally influenced eating habits and physical activity levels that led to weight gain, and hence higher vulnerability to COVID-19 infection and negative outcomes. This analysis provides public health agencies with data to tailor nutrition interventions that mitigate the observed adverse lifestyle behaviors.

Evaluation of Zygomaticomaxillary Complex Fractures with Gillies Approach in Al-Baha Region of Saudi Arabia: A Cohort Study.

The aim of this study was to evaluate the accuracy of the degree of fracture reduction after open reduction and internal fixation of Zygomaticomaxillary Complex (ZMC) fractures in the Saudi population of the Al-Baha region, using Gillies approach. Further comparison with preoperative and postoperative standardized computed tomography (CT) views with the calculation of residual deformity percentage, which remained after the ZMC rehabilitation. A 5-year retrospective CT-based study on preoperative and postoperative axial CT scans of 46 male patients with ZMC fractures. The CT measurements were made (in millimeters) at the fracture site of maximum displacement through the anterior orbital rim and orbital floor, posterolateral wall of the maxillary sinus, zygomatic arch, and zygomaticofrontal suture. For the zygomatic arch, measurements were made (in mm) by drawing a tangent to the fractured arch segments and dropping a perpendicular to the inward displaced fractured arch. The total difference in all measured parts between preoperative and postoperative displacement was calculated in percentages. Upon comparison of preoperative and postoperative zygomaticomaxillary complex CTs, three-point fixation at the regions of infraorbital rim, frontozygomatic suture, and posterolateral wall of the maxilla results in a reduction of the fracture sites in the range of 72.85% to 85%. Maximum reduction was noted at the zygomatic arch, that is, 85%, and minimum at the infraorbital rim, that is, 72.85%. The reduction obtained at all four sites was statistically significant, with P values ranging from .011 to .039. Gillies temporal approach and three-point fixation at the regions of the infraorbital rim, frontozygomatic suture, and posterolateral wall of the maxilla results in satisfactory treatment of ZMC fractures and improves patients oral health and quality of life.

Determinants of Food Ordering Applications Adoption among Saudi Consumers and their Effect on Dietary Habits

Objectives: This study aims to contribute knowledge toward understanding the effect of food ordering applications (FOA) on consumer behavior regarding food consumption and dietary habits of the Saudi population. Methods: This cross-sectional study tested the Theory of Planned Behavior (TPB) within the domain of FOA with adult users (N=834) using an online questionnaire. Results: Structural equation modeling (SEM) analysis revealed that among the TPB constructs, attitude had the largest positive and direct effect on participants' intention in FOA's adoption followed by subjective norms and perceived behavioral control variables. Overall, the 3 TBP constructs accounted for 49% of the variance in intention, whereas intention accounted for 33% of the variance in behavior. Conclusion: Our results suggest that TPB constructs represent an important aspect in studying consumer behavior regarding FOA. Moreover, the use of FOA may influence healthy dietary habits.

Evaluation of Styloid Process Elongation in Madinah, Saudi Arabia: A Retrospective Radiographic Investigation.

This study aimed to identify the prevalence of an elongated styloid process and analyze the presence of its calcification in the Saudi population using panoramic radiographs. The Taibah Outpatient Dental Clinic's OPG radiographs for 962 patients who attended screening clinics between December 2022 and October 2023 were all included in the study. Patients' demographics, such as age, gender, and nationality, as well as radiological data, were included in the following study variables: the presence of an elongated styloid on both sides of a panoramic radiograph, right side styloid length, left side styloid length, right side distal end thickness, and left side distal end thickness. The study evaluated 438 (45.5%) processes found in individuals aged 16-80 years old. The elongated process length ranged from 30.0 to 40.1 mm, and the diameter ranged from 0.81 to 7.79 mm at the origin to 0.56-3.79 mm at the end. There was no statistically significant difference in process length across genders or age groups. The diameters of the styloid bones on the left side vary significantly across genders at the start and completion of the process. The prevalence of elongated styloids in the studied population was 4.26%. The radiological evaluation of the styloid process is a crucial stage in dental surgery planning.

Novel mutation in alpha-spectrin gene in Saudi patients with hereditary spherocytosis

Hereditary spherocytosis (HS) is the most common hereditary hemolytic disorder induced by red blood cell (RBC) membrane defect. This study was undertaken to determine mutations in genes associated with RBC membrane defect in patients with HS such as α-spectrin gene (SPTA1), β-spectrin gene (SPTB), ankyrin gene (ANK1), band 3 anion transport gene (SLC4A1) and erythrocyte membrane protein band 4.1 gene (EPB41). Blood samples were collected from 23 unrelated patients with HS. Patients were diagnosed according to the guidelines from the British Society for Hematology. All hematological examinations for the determination of RBC abnormalities and osmotic fragility tests were conducted. Genomic DNA were extracted from peripheral blood cells and coding exons of known genes for hereditary spherocytosis were enriched using Roche/KAPA sequence capture technology and sequenced on an Illumina system via next-generation sequencing (NGS). The data showed that most of the HS patients confirmed splenomegaly and showed elevated reticulocytes and abnormal bilirubin values. NGS analysis identified the heterozygous variant c.5501G > A in the exon 39 of SPTA1 gene, resulted in a Trp1834*, which leads to a premature stop codon and subsequent mRNA degradation (nonsense- mediated decay) or truncation in α spectrin. Moreover, our data also revealed conventional mutations in genes SPTB, ANK, SLC4A1 and EBP41 in severe patients of HS. In short, this is the first report that determined a novel mutation c.5501G > A in SPTA1 gene in the Saudi population. To the best of our knowledge, this variant c.5501G > A has not been described in global literature so far. This novel mutation in SPTA1 gene is unique in the Saudi population.

Etiological Factors Affecting Single Versus Multiple Tunneled Hemodialysis Catheter Cuff Extrusions in the Saudi Population.

To identify underlying factors associated with single versus multiple expulsions of tunneled hemodialysis catheter cuffs and their associated complications. A multicenter, five-year retrospective data analysis was conducted on hemodialysis patients with tunneled catheters. Patient data included age, gender, BMI, and associated comorbidities. The type of procedure (new tunnel insertion vs. exchange), exit site infection, and catheter-related bloodstream infection (CRBSI) were also included. The data of 122 patients was analyzed. Seventy-eight patients had diabetes mellitus, 102 patients had hypertension, and 24 had ischemic heart disease. Fifty-one patients were on antiplatelet therapy, and nine patients were on oral steroids. The access site for 98 patients was the right internal jugular; for 19 patients, it was the left internal jugular; five patients had a femoral dialysis catheter. Patients were grouped into two categories: those with single cuff extrusion episodes and those with multiple cuff-out episodes. Sixty-three patients had one cuff extrusion, and 59 had multiple cuff-out episodes during the study period. Patients who had CRBSI and hypertension and were aged between 61 and 95 had multiple episodes of cuff extrusion and reached statistical significance. Exit-site infection, diabetes mellitus, antiplatelet therapy, gender, catheter site, and BMI had no statistical significance between the two groups. Tunneled catheter cuff extrusion is a frequent phenomenon. Catheter-related bloodstream infection, hypertension, and age of 61 to 95 years are high-risk factors for multiple episodes of cuff extrusion.
