Rural-urban differences in meeting of physical activity recommendations by sun exposure and protection behaviors in the United States.

OBJECTIVE: To examine associations between sun protection behaviors and physical activity (PA) by rural and urban residence in the United States. METHODS: We analyzed data from the National Health and Nutrition Examination Survey (2013-2018), restricting to participants ages 20-59 with sun behavior data. Sunburns, sun exposure, and sun protection measures were dichotomized (yes/no): ≥1 sunburn in the past year, 2+ hour outside during workdays or non-workdays, and never/rarely/sometimes using sunscreen, wearing long sleeves, and staying in the shade. Meeting PA recommendations (yes/no) was defined as ≥150 min of vigorous/moderate or ≥ 75 min vigorous PA per week. Associations between sun behaviors and PA were analyzed using logistic regression models, which accounted for survey-weights and potential confounders, and stratified by rural-urban status. RESULTS: Rural and urban individuals meeting PA recommendations had greater odds of spending 2+ hour outside during workdays (OR: 2.26 [1.88, 2.74] and 3.95 [2.72, 5.73]) and non-workdays (OR: 2.06 [1.78, 2.38] and 3.33 [2.47, 4.46]). Among urban residents, odds of staying in the shade were lower among those who met PA recommendations (OR: 0.78 [0.66, 0.92]). We did not observe differences in sunburns or other sun behaviors by PA status, regardless of rurality. CONCLUSIONS: Meeting PA recommendations was associated with greater sun exposure in both rural and urban populations. Additional exercise location (indoors/outside) data is needed to inform PA and skin cancer prevention interventions to reduce unintended increases in sun exposure and reductions in PA, respectively, especially among rural populations.

Deep palmar phenotyping in atopic eczema: patterns associated with filaggrin variants, disease severity and barrier function in a South Asian population.

BACKGROUND: Hyperlinear palms are described as a feature of loss-of-function (LoF) variants in filaggrin (FLG). OBJECTIVES: To explore the phenotype of participants (age < 31 years) with atopic eczema of Bangladeshi ancestry from East London and investigate which factors best associate with LoF FLG variants. METHODS: A cross-sectional study with participants recruited between May 2018 and December 2020. Patterns of palmar linearity were categorized and modelled with the Eczema Area and Severity Index (EASI), transepidermal water loss (TEWL), skin hydration (SH) and LoF FLG variants. RESULTS: There were 506 complete cases available. Five palm patterns were noted. The 'prominent diamond' pattern associated best with EASI [marginal effects (ME) 2.53, 95% confidence interval (CI) 1.74-3.67], SH (ME 0.85, 95% CI 0.78-0.96) and TEWL (ME 1.32, 95% CI 1.11-1.62). Using five palm patterns had some ability to discriminate LoF FLG variants [area under the receiver operator characteristic (AUROC) 76.32%, 95% CI 71.91-80.73], improving to 77.99% (73.70-82.28) with the addition of SH. In subgroup analysis with only fine perpendicular/prominent diamond patterns the AUROC was 89.11% (95% CI 84.02-94.19). CONCLUSIONS: This was a single-centre study design with humans classifying clinical patterns. The stability of temperature and humidity was not guaranteed across TEWL and SH measurements despite using a climate-controlled room. Palm patterns associate with EASI and TEWL. The fine perpendicular/prominent diamond patterns are markers to detect the absence/presence of LoF FLG variants, respectively.

Cross-sectional study of sex differences in psychosocial quality of life of long-term melanoma survivors.

PURPOSE: A cancer diagnosis and subsequent treatment can have a significant impact on an individual's quality of life. Differences in quality of life by sex among long-term melanoma survivors remain unclear. The objective of this study was to describe sex differences in cancer-specific psychosocial quality of life of long-term melanoma survivors. METHODS: Melanoma survivors 7-10 years post-diagnosis from a previously conducted population-based case-control study were recruited for a cross-sectional survey. Validated measures of psychosocial quality of life related to melanoma diagnosis were assessed. Outcomes were compared by sex using linear regression models adjusting for age, education, income, and marital status. RESULTS: The survey response rate was 62% (433 females, 291 males; 86% stage I disease). Females were more likely to report changes in their appearance (p = 0.006) and being more fearful of recurrence (p = 0.001) or a second melanoma (p = 0.001) than males but were also more likely to report that melanoma had a positive impact on their lives (p < 0.0001). Males were more likely to agree with statements that emphasized that life's duration is limited (p < 0.0001). CONCLUSION: Long-term melanoma survivors reported generally favorable measures of psychosocial quality of life related to their diagnosis. Females and males reported unique quality of life concerns and may require varied methods of support following a melanoma diagnosis.

Effect of steroid hormone receptor gene variants PROGINS (Alu insertion) and PGR C/T (rs1042839) as a risk factor for recurrent pregnancy loss in Kashmiri population (North India).

AIM: To unveil and evaluate the association and analyze the incidence and pattern of PGR gene polymorphisms (PROGINS insertion and PGR exon 5-C/T polymorphism) in recurrent pregnancy loss (RPL) couples of Kashmir. METHODS: In this study, analyses of PGR gene polymorphisms in RPL couples were genotyped by amplification-refractory mutation system polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism. RESULTS: Molecular analysis of PGR gene polymorphisms indicated that the genotypic and allelic frequencies of PROGINS insertion and PGR exon 5 C/T polymorphisms of female group in cases and controls to be significantly different and poses risk in predisposition to RPL. Moreover, haplotype analysis in female group revealed that P1P2/CC and P1P2/CT genotype are significantly associated with RPL. CONCLUSION: Our data indicate that the PROGINS insertion and exon 5-C/T polymorphism can act as useful genetic markers in the female group, but needs to be replicated in further studies including various other single nucleotide polymorphisms of PGR gene relevant to pregnancy loss which may contribute to novel therapeutic targets with improved conclusions.

Initial skin cancer screening for solid organ transplant recipients in the United States: Delphi method development of expert consensus guidelines.

Skin cancer is the most common malignancy affecting solid organ transplant recipients (SOTR), and SOTR experience increased skin cancer-associated morbidity and mortality. There are no formal multidisciplinary guidelines for skin cancer screening after transplant, and current practices are widely variable. We conducted three rounds of Delphi method surveys with a panel of 84 U.S. dermatologists and transplant physicians to establish skin cancer screening recommendations for SOTR. The transplant team should risk stratify SOTR for screening, and dermatologists should perform skin cancer screening by full-body skin examination. SOTR with a history of skin cancer should continue regular follow-up with dermatology for skin cancer surveillance. High-risk transplant patients include thoracic organ recipients, SOTR age 50 and above, and male SOTR. High-risk Caucasian patients should be screened within 2 years after transplant, all Caucasian, Asian, Hispanic, and high-risk African American patients should be screened within 5 years after transplant. No consensus was reached regarding screening for low-risk African American SOTR. We propose a standardized approach to skin cancer screening in SOTR based on multidisciplinary expert consensus. These guidelines prioritize and emphasize the need for screening for SOTR at greatest risk for skin cancer.

Rural-Urban Differences in Sun Exposure and Protection Behaviors in the United States.

BACKGROUND: Evidence regarding whether rural residence is a risk factor for skin cancer is mixed. We compared sun exposure and protection behaviors between rural and urban residents by ethno-racial group in the United States. METHODS: We analyzed data from three (2013-2018) National Health and Nutrition Examination Survey cycles. We compared self-reported sun exposure and protection measures (sunburn, time spent outside, sunscreen use, wearing long sleeves, staying in shade) by rural-urban residential status using survey-weighted logistic regression models stratified by ethno-racial group, adjusting for age, sex, income, education, body mass index, and smoking. RESULTS: Hispanic rural versus urban residents more often reported sunburns in the past year [41.6% vs. 31.2%, adjusted OR (aOR): 1.46 (1.15-1.86)]. White rural versus urban residents more often spent 2+ hours outside on workdays [42.9% vs. 29.1%, aOR: 1.60 (1.27-2.01)] and non-workdays [72.2% vs. 64.8%, aOR: 1.45 (1.12-1.88)] and less often used sunscreen [26.0% vs. 35.1%, aOR: 0.74 (0.59-0.93)] and stayed in the shade [21.7% vs. 26.7%, aOR: 0.72 (0.57-0.89)]. Black rural versus urban residents stayed in the shade less often [31.6% vs. 43.9%, aOR: 0.60 (0.39-0.91)] but less often spent 2+ hours outside on non-workdays [47.6% vs. 56.8%, aOR: 0.67 (0.51-0.90)]. CONCLUSIONS: Across all ethno-racial groups included, rural residents reported greater sun risk behaviors than urban residents, with some nuances by ethno-racial identity, suggesting rural residence is a potential risk factor for skin cancer. IMPACT: Sun protection promotion programs should consider rural-urban settings while also accounting for ethno-racial identities.

Capecitabine to reduce nonmelanoma skin carcinoma burden in solid organ transplant recipients.

BACKGROUND: Solidorgan transplant recipients (SOTRs) are at greater risk of nonmelanoma skin cancer (NMSC) than the general population, in large part because of their immunosuppression. Select individual SOTRs demonstrate a rate of tumor development at the upper end of their cohort. Capecitabine, a prodrug converted in the body to 5-fluorouracil (5-FU), may alter the risk for development of NMSC in an individual SOTR with a high rate of tumor development. OBJECTIVE: To report observations of a series of 10 SOTRs treated with capecitabine as adjuvant prevention for high-incidence NMSC. METHODS: Ten SOTRs were administered cycles of low-dose oral capecitabine (0.5-1.5 g/m(2) per day) for days 1 to 14 of a 21-day treatment cycle. Measurements (skin screenings, laboratory and toxicity monitoring) were performed every 1 to 3 months. Incidence rates of squamous cell carcinoma (SCC) before and during treatment were determined and compared using the Wilcoxon signed-rank test. RESULTS: The average incidence rate (mean ± SD) of SCC before treatment (0.56 ± 0.28 SCCs/month, range 0.17-1.17 SCCs/month) declined to 0.16 ± 0.11 SCCs/month (range 0-0.33 SCCs/month) during the first 12 months of treatment (mean reduction 68 ± 30.0%, range 0-100%, p < .005). Reduction in actinic keratosis was observed. Common side effects included fatigue, nausea, hand-and-foot syndrome, gout, and poor renal function. Seven of 10 participants required dose adjustment, and two of these were discontinued from the study drug because of side effects. LIMITATIONS: Case series design, small observational population. CONCLUSIONS: SOTRs experienced a clinically and statistically significant decline in incident SCCs during treatment with low-dose oral capecitabine, with varying degrees of side effects. Larger randomized trials will determine the dose and efficacy of capecitabine for adjuvant treatment of NMSC in SOTRs.

48-hours administration of nifedipine in spontaneous preterm labor - Doppler blood flow assessment of placental and fetal circulation.

OBJECTIVES: The aims were to assess the placental and fetal circulation during nifedipine tocolysis within the first 48 hours of therapy. METHODS: Placental and fetal circulation was assessed in Doppler ultrasound examination prior to nifedipine administration and then after 24 and 48 hours. Maternal heart rate and PI in uterine arteries were evaluated as well as FHR, RI and PI of UA and MCA. E/A-wave ratio for A-V valves, MPI and SF were calculated for both ventricles independently. To determine changes over time in all study variable analysis of variance (ANOVA) for repeated measurements followed by Tukey-Kramer's multiple comparison test was used. The effects of additional clinical covariates were checked. RESULTS: Uterine and umbilical blood flow patterns were not altered significantly during administration of nifedypine tocolysis. While MCA Doppler indicies such as RI and PI were unchanged, the evaluation of MCA PSV revealed a transient significant decrease after 24 hours. A resolution of this distraction was observed within the following 24 hours. No significant changes were observed in direct fetal cardiac function parameters calculated separately for both ventricles. CONCLUSIONS: The decrease of MCA PSV after 24 hours of treatment was isolated and transient hemodynamic distraction observed during treatment. Neither fetal cardiac parameters nor other Doppler indices were changed. Therefore oral administration of nifedipine seems not to alter uterine nor fetal arterial blood flow pattern seriously. As significant changes were observed by different authors, further studies should be performed to verify the optimal total dose of nifedipine and its influence on hemodynamic conditions.

Doppler evaluation of blood flow in fetal inferior vena cava during 48-hours Atosiban administration in spontaneous preterm labor.

OBJECTIVES: The aims were to evaluate whether any changes in blood flow in fetal inferior vena cava (IVC) are observed during Atosiban tocolysis within the first 48 hours of therapy. METHODS: Detailed Doppler evaluation of blood flow in fetal IVC was performed prior to Atosiban administration and after 24 and 48 hours respectively. Maternal and fetal heart rate was assessed. IVC Doppler indices, such as, S/D (systole/diastole), PVIV (peak velocity index for the vein) and PLI (preload index) were calculated. To determine changes over time in all study variables, analysis of variance (ANOVA) for repeated measurements was used and followed by Tukey-Kramer's post hoc test. The effects of additional clinical covariates were checked. RESULTS: Maternal heart rate was not altered significantly during Atosiban administration. No significant changes in FHR (fetal heart rate) as well as following IVC Doppler parameters (S/D, PVIV) were recorded after 24/48 hours of tocolytic treatment. The fetal IVC PLI values were significantly reduced after 24 hours and 48 hours of treatment. The changes in PLI values when comparing 24 and 48 hours results were not statistically significant. CONCLUSIONS: As the questions about drug safety appeared after the animal study had been published about possible myocyte injury, detailed Doppler evaluation of IVC blood flow was performed. It revealed the changes in preload conditions which could be a reflection of successful Atosiban tocolytic treatment. No hemodynamic changes in IVC were noted, suggesting the presence of fetal acidemia due to possible heart damage was observed.

48-hours administration of fenoterol in spontaneous preterm labor - does it affect fetal preload?

OBJECTIVE: to investigate whether any changes in the preload index (PLI) occur within the first 48 hours of fenoterol intravenous tocolysis. MATERIAL AND METHODS: Doppler evaluation of placental and fetal circulation was performed in 36 pregnant women prior to fenoterol administration and after 24/48 hours. Measurements were obtained from a longitudinal section of the inferior vena cava (IVC) and preload index was calculated. To determine changes over time, an all study variable analysis of variance (ANOVA) for repeated measurements, followed by Tukey-Kramer's multiple comparison test was used. The effects of additional clinical covariates were checked. RESULTS: The maternal heart rate values were significantly increased after 24 hours and 48 hours in comparison to pre-treatment values. No significant changes in fetal heart rate were observed during treatment. The fetal IVC PLI values were significantly reduced after 24 hours and 48 hours of treatment. The increase in PLI values when comparing 24 and 48 hours results were not statistically significant. These observations were consistent with ANOVA post-hoc analysis. CONCLUSIONS: 48 hours intravenous administration of fenoterol appears not to alter inferior vena cava blood flow by itself. The reduction in PLI values may reflect lower fetal preload conditions during the course of successful tocolytic treatment. Therefore, Doppler IVC PLI measurement should be considered as a possible additional assessment method of effectiveness of treatment. However, other Doppler venous blood flow parameters should be assessed to confirm the results and clarify whether maternal corticosteroids administration may be interfering with the results.

48-hours administration of fenoterol in spontaneous preterm labor - Doppler blood flow assessment of placental and fetal circulation.

OBJECTIVES: The aims were to investigate whether any changes in placental and fetal circulation were observed during fenoterol tocolysis within the first 48 hours of therapy. MATERIAL AND METHODS: Doppler evaluation of placental and fetal circulation was performed prior to fenoterol administration and then after 24 and 48 hours. Maternal heart rate and pulsatility index (PI) in uterine arteries were assessed. FHR, RI and PI of umbilical artery and middle cerebral artery were measured. E/A ratio for A-V valves, the myocardial performance index (MPI) and shortening fraction (SF) were calculated for both ventricles independently. The blood flow pattern in DV was assessed using PI, S/a ratio and peak velocity index for the vein. To determine changes over time in all study variable analysis of variance (ANOVA) for repeated measurements followed by Tukey-Kramer's multiple comparison test was used. The effects of additional clinical covariates were checked. RESULTS: Uterine and fetal arterial blood flow patterns were not altered significantly during 48 hours of tocolysis. No significant changes were observed in fetal cardiac function parameters as well. The evaluation of Doppler parameters in the DV revealed a significant increase in PVIV after 48 hours. Additionally after 48 hours of successful tocolysis S/a ratio values were significantly lower. CONCLUSIONS: Short term intravenous administration of fenoterol seems not to alter uterine and fetal arterial blood flow pattern. Direct fetal cardiac function remained unaffected. However significant changes of selected Doppler parameters in DV may suggest further studies should be performed to assess more precisely fetal venous blood flow.

Incidental sun exposures as a source of sunburn among rural compared to urban residents in the United States.

PURPOSE: Melanoma incidence is higher in rural than in urban areas in the United States, possibly due to greater incidental sun exposures from rural outdoor-focused lifestyles and occupational patterns. Our aim was to compare activities at the time of a sunburn between rural and urban residents. METHODS: Utilizing the nationally representative 2019 cross-sectional Health Information National Trends Survey (HINTS), we report odds ratios (OR) and confidence intervals (CI) from logistic regression models comparing self-reported activities at most recent sunburn among rural versus urban adults. FINDINGS: About one-third of participants (37.2%) reported a sunburn in the past year, higher in urban (38.0%) than in rural populations (32.5%). At the time of most recent sunburn, swimming (36.6%) and working outside a home (29.4%) were the most commonly reported activities. Working on a job (30.4% vs 10.4%; OR: 3.30, 95% CI: 1.33, 8.20) or outside the house (38.7% vs 28.1%; OR: 1.86, 95% CI: 1.03, 3.33) were more common, while exercising or sunbathing were less common, among rural compared to urban participants. CONCLUSIONS: Incidental sun exposures during outdoor-focused rural occupations and work outside the house may be critical skin cancer prevention targets in rural populations; outdoor exercise and sunbathing may be more important in urban populations; incidental exposures while swimming may be important in both populations.

Cross-sectional study of physical activity among long-term melanoma survivors and population controls.

Physical activity has been associated with improved outcomes among cancer survivors of various malignancies; however, this topic is understudied among melanoma survivors. Our objective was to determine whether long-term melanoma survivors are less likely to meet American Cancer Society physical activity guidelines than non-melanoma population controls. We conducted a cross-sectional survey in 2015 to follow up participants from a case-control study of melanoma and population controls in Minnesota. The primary outcome was meeting American Cancer Society recommendations for healthy physical activity levels. Physical activity, sun protection practices and time spent outside were compared between survivors and controls using generalized linear regression models. Melanoma survivors (N = 724) and controls (N = 639) were similar with the exceptions of daily hours spent outside, sun protection scores, skin tone, and smoking status. Half (50.8%) of melanoma survivors reported meeting the physical activity guidelines, compared to 39.7% of controls (p < 0.0001), with an 11% (95% CI 0.05-0.17) difference after adjusting for potential confounders. While long-term melanoma survivors were more likely to meet American Cancer Society physical activity guidelines than population controls, nearly 50% did not meet recommendations. This finding is concerning given the known improvements in quality of life and survival among physically active cancer survivors. Opportunities remain to promote physical activity among melanoma survivors. Health communications that promote outdoor exercise, in particular, should include advice about sun protection.

A UVR-sensor wearable device intervention to reduce sun exposure in melanoma survivors: Results from a randomized controlled trial.

BACKGROUND: Melanoma survivors are at increased risk of developing a second primary melanoma; however, some report sub-optimal sun behaviors and sunburns. We tested the effectiveness of a wearable device with ultraviolet radiation (UVR)-sensing technology to improve sun behaviors and reduce sunburns in cutaneous melanoma survivors. MATERIALS AND METHODS: We conducted a randomized controlled trial using Shade 2, a commercially available wrist device that measures UVR. The intervention group received the device and mobile application notifications about their exposure and prompts to use sunscreen. The control group received the device and a separate research mobile application without information about their exposure or notifications. Participants wore the device for 12 weeks and self-reported sun behaviors before, during, and after the intervention. The primary outcome was a composite score of sun protection behaviors at week 12. RESULTS: 386 participants were randomized (186 control, 182 intervention). Most were female and 5+ years past their first melanoma diagnosis. The average age was 56 years. Most (93%) completed the study, though 40% experienced device issues. No meaningful differences were observed in self-reported sun protection behaviors at week 12 (controls 3.0±0.5 vs. intervention 2.9±0.5, p = 0.06), any sunburn during the intervention period (controls 14.4% vs. intervention 12.7%, p = 0.75), or average daily objective UVR exposure (controls median 87 vs. intervention 83 J/m2, p = 0.43). CONCLUSION: Wearing a device that measured and alerted melanoma survivors to UVR exposure did not result in different sun behaviors, exposure, or sunburns relative to controls. The technology needs refinement before further attempts to assess the effectiveness of self-monitoring UVR exposure. CLINICAL TRIALS REGISTRATION: NCT03927742.

A nationwide evaluation of bevacizumab-based treatments in pediatric low-grade glioma in the UK: Safety, efficacy, visual morbidity, and outcomes.

BACKGROUND: Bevacizumab is increasingly used in children with pediatric low-grade glioma (PLGG) despite limited evidence. A nationwide UK service evaluation was conducted to provide larger cohort "real life" safety and efficacy data including functional visual outcomes. METHODS: Children receiving bevacizumab-based treatments (BBT) for PLGG (2009-2020) from 11 centers were included. Standardized neuro-radiological (RANO-LGG) and visual (logMAR visual acuity) criteria were used to assess clinical-radiological correlation, survival outcomes and multivariate prognostic analysis. RESULTS: Eighty-eight children with PLGG received BBT either as 3rd line with irinotecan (85%) or alongside 1st/2nd line chemotherapies (15%). Toxicity was limited and minimal. Partial response (PR, 40%), stable disease (SD, 49%), and progressive disease (PD, 11%) were seen during BBT. However, 65% progressed at 8 months (median) from BBT cessation, leading to a radiology-based 3 yr-progression-free survival (PFS) of 29%. Diencephalic syndrome (P = .03) was associated with adverse PFS. Pre-existing visual morbidity included unilateral (25%) or bilateral (11%) blindness. Improvement (29%) or stabilization (49%) of visual acuity was achieved, more often in patients' best eyes. Vision deteriorated during BBT in 14 (22%), with 3-year visual-PFS of 53%; more often in patients' worst eyes. A superior visual outcome (P = .023) was seen in neurofibromatosis type 1-associated optic pathway glioma (OPG). Concordance between visual and radiological responses was 36%; optimized to 48% using only best eye responses. CONCLUSIONS: BBTs provide effective short-term PLGG control and delay further progression, with a better sustained visual (best > worst eye) than radiological response. Further research could optimize the role of BBT toward a potentially sight-saving strategy in OPG.

Weight lifting in women with breast-cancer-related lymphedema.

BACKGROUND: Weight lifting has generally been proscribed for women with breast-cancer-related lymphedema, preventing them from obtaining the well-established health benefits of weight lifting, including increases in bone density. METHODS: We performed a randomized, controlled trial of twice-weekly progressive weight lifting involving 141 breast-cancer survivors with stable lymphedema of the arm. The primary outcome was the change in arm and hand swelling at 1 year, as measured through displaced water volume of the affected and unaffected limbs. Secondary outcomes included the incidence of exacerbations of lymphedema, number and severity of lymphedema symptoms, and muscle strength. Participants were required to wear a well-fitted compression garment while weight lifting. RESULTS: The proportion of women who had an increase of 5% or more in limb swelling was similar in the weight-lifting group (11%) and the control group (12%) (cumulative incidence ratio, 1.00; 95% confidence interval, 0.88 to 1.13). As compared with the control group, the weight-lifting group had greater improvements in self-reported severity of lymphedema symptoms (P=0.03) and upper- and lower-body strength (P<0.001 for both comparisons) and a lower incidence of lymphedema exacerbations as assessed by a certified lymphedema specialist (14% vs. 29%, P=0.04). There were no serious adverse events related to the intervention. CONCLUSIONS: In breast-cancer survivors with lymphedema, slowly progressive weight lifting had no significant effect on limb swelling and resulted in a decreased incidence of exacerbations of lymphedema, reduced symptoms, and increased strength.

The Frequency of Rh Phenotype and Its Probable Genotype.

AIMS AND OBJECTIVES: Our goal is to disseminate data on the distribution pattern of Rh antigen, its phenotypes, and the likely genotypes of these genetic variants in the Pakistani population. METHODOLOGY: This study was a cross-sectional research project. Patients' demographic statistics, such as age and gender, were gathered from their medical information. Blood group, disease, RhD, and other antigen frequency, phenotype, and probable genotype were considered variables. All blood samples were phenotyped for Rhesus antigens (D, C, c, E, and e), and the test was carried out using the tubing technique. RESULTS: According to gender distribution, most of the patients were males, with 131 frequencies (57.7%), while females had 42.35%. The most common phenotype was DCCee, with its probable genotype DCe/DCe (R1 R1) (34%), followed by DCcee, with probable genotype DCe/ce (R1 r) (29.1%); the least common phenotype was ddCcee, with its probable genotype Ce/ce (r ' r) (0.4%). CONCLUSION: It is concluded that the DCCee phenotype was the most common with its probable genotype DCe/DCe, while the least common phenotype was ddCcee with its probable genotype Ce/ce.

Frequency of Specific and Non-specific Inhibitors in Haemophilia A Patients.

OBJECTIVE: To determine the frequency of specific and non-specific inhibitors in haemophilia A patients. STUDY DESIGN: This is a cross-sectional study. PATIENTS AND METHODS: A total of 150 male haemophilia A patients were included in this cross-sectional study at the National Institute of Blood Diseases and Bone Marrow Transplant (NIBD), Karachi, Pakistan, from September 2019 to January 2022. RESULTS: Among 150 patients included in this study, 23 (15.3%) had an inhibitor and 127 (84.6%) did not. All patients had specific inhibitors against Factor VIII (FVIII). Non-specific inhibitors were not identified in our population. Among the patients in the inhibitor group, there were 13 (56.5%) in the severe (<1%) category. There were 10 (43.5%) patients in the moderate (1-5%) category. There were no patients in the mild category. The median inhibitor level was 15.4 Bethesda unit (BU). CONCLUSION: The development of inhibitors has not been identified as a major problem in our population. However, it is noteworthy that only 15.3% of patients with haemophilia A developed inhibitors in this data set. They were essentially treated with plasma and its products.

The Outcome of Hodgkin Lymphoma With Reference to Prognostic Markers.

OBJECTIVES: This study aimed to determine the impact of prognostic markers on the outcomes of Hodgkin lymphoma. METHODS: It is a cross-sectional, single-center study. A total of 60 patients diagnosed with Hodgkin lymphoma were recruited for the study over five years between 2016 to 2020. The study setting was the National Institute of Blood and Bone Marrow Transplant in Pakistan. The Statistical Package for Social Sciences (SPSS) version 23 (IBM Corp., Armonk, NY, USA) was used for statistical analysis. RESULTS: In the study population, 63.3% of the patients were male (38/60), and 36.7% were female (22/60). Hodgkin lymphoma was divided into four stages: stage I (18.3%), stage II (18.3%), stage III (46.7%), and stage IV (16.7%). Patients in stage III had a higher value of hemoglobin (Hb) than in other stages of the disease. The erythrocyte sedimentation rate was high in 56.7% of stage III patients than in patients of the other stages. The lactate dehydrogenase (LDH) levels were not under the normal range in 51.6% of patients. Only 20% of patients in stage III had LDH values within the normal range, whereas 26.6% did not. CONCLUSION: There was a significant impact of prognostic factors on the survival of patients with Hodgkin lymphoma.
