The present study aims to investigate the mutation spectrum of thalassaemia, and characterise the erythrocyte indices of thalassaemia in a large cohort in Sichuan, which is a province with a high prevalence of thalassaemia in southern China.
The present study was conducted from July 2017 to July 2019. A total of 42 155 women screened for thalassaemia were enrolled. The thalassaemia carriers were screened by erythrocyte analysis and haemoglobin electrophoresis. Then, the screening test results and genetic results were collected.
A total of 1109 individuals had thalassaemia gene defects. Among these individuals, 69.7% were α-thalassaemia (α-thal) and 28.6% were β-thalassaemia (β-thal). For α-thal defects, carriers with
had the lowest mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) values. For β-thal defects, carriers with heterozygous haemoglobin E and -28 had the highest MCV and MCH values. In addition, an MCV cut-off of 80 fl and an MCH cut-off of 27 pg was able to detect 99.1% α0 thalassaemia and 99.7% β0/β+ thalassaemia; however, that criterion could result in a great number of false-negative results in α+ carriers.
A criterion of MCV <80 fl and MCH <27 pg is recommended for detecting -SEA carriers and β0/β+ carriers, while higher cut-offs are needed to detect α+ carriers.
A criterion of MCV less then 80 fl and MCH less then 27 pg is recommended for detecting -SEA carriers and β0/β+ carriers, while higher cut-offs are needed to detect α+ carriers.
There is little evidence on the impact of national pressures on primary care provision for type 2 diabetes from the perspectives of patients, their GPs, and nurses.
To explore experiences of primary care provision for people with type 2 diabetes and their respective GPs and nurses.
A qualitative primary care interview study in the East of England.
Semi-structured interviews were conducted, between August 2017 and August 2018, with people who have type 2 diabetes along with their respective GPs and nurses. Purposive sampling was used to select for heterogeneity in glycaemic control and previous healthcare experiences. Interviews were audio-recorded and analysed thematically. The consolidated criteria for reporting qualitative research were followed.
The authors interviewed 24 patients and 15 GPs and nurses, identifying a changing landscape of diabetes provision owing to burgeoning pressures that were presented repeatedly. Patient responders wanted GP-delivered care with continuity. They saw GPs as exectations of care, by communicating solutions to both patients and providers so that they are understood, managed, and realistic, may be one way forward.
A raised platelet count (thrombocytosis) measuring >400 × 10
/l is associated with high cancer incidence. It is uncertain whether platelet counts at the upper end of the normal range (high-normal 326-400 × 10
/l) are also associated with cancer.
To investigate cancer incidence following a normal platelet count in primary care.
A prospective cohort study was undertaken using data from the Clinical Practice Research Datalink and National Cancer Registration and Analysis Service, dating from 1 May 2005 to 30 April 2014.
One-year cancer incidence was estimated for 295 312 patients with normal platelet counts (150-400 × 10
/l). Patients with platelet counts >325 × 10
/l were oversampled to maximise precision of estimates of cancer incidence. All patients were aged ≥40 years with no prior cancer diagnoses. The effects of age, sex, and smoking were explored. Non-melanoma skin cancers were omitted from exclusions and incidence.
One-year cancer incidence increased greatly with age, male sex, and higher platelet count. Males aged ≥60 years with a high-normal count had an incidence of 4.2% (95% confidence interval [CI] = 4.0 to 4.4). The highest incidence of 6.7% (95% CI = 5.3 to 8.4) was found in males aged ≥80 years, who had platelets in the range of 376-400 × 10
/l; this was 3.1 percentage points higher than the incidence for patients in the same age group with lower-normal counts of 150-325 × 10
/l. Risks for all female subgroups were <3%. check details Patients with high-normal platelet counts were most at risk of lung and colorectal cancers and, in general, had advanced-stage cancer at diagnosis.
Platelet counts at the high-normal range in males aged ≥60 years may be indicative of an underlying malignancy, and referral for further investigation should be considered.

KHARON is located in three distinct regions of the cytoskeleton the base of the flagellum, the subpellicular microtubules, and the mitotic spindle. To deconvolve the different functions for KHARON, we have identified two partner proteins, KHAP1 and KHAP2, which associate with KHARON. KHAP1 is located only in the subpellicular microtubules, whereas KHAP2 is located at the subpellicular microtubules and the base of the flagellum. Both KHAP1 and KHAP2 null mutants are unable to execute cytokinesis but are able to traffic GT1 to the flagellum. These results confirm that KHARON assembles into distinct functional complexes and that the subpellicular complex is essential for cytokinesis and viability of disease-causing amastigotes but not for flagellar membrane trafficking.
Menthol smokers (particularly African-Americans) have lower cessation success rates than non-menthol smokers. With bans being considered on characterising menthol flavour in cigarettes, data are needed regarding how switching to non-menthol cigarettes impacts cessation measures.
In this randomised pilot study, African-American menthol cigarette smokers interested in quitting smoking either continued smoking menthol cigarettes (n=60) or switched to non-menthol cigarettes (n=62) for a 1-month period prior to a cessation attempt. The primary endpoint was time to smoking lapse (ie, time from quitting until any smoking). Additional endpoints included time to smoking relapse (ie, number of days from quitting until the first of seven consecutive smoking days) and difference between groups in subjective measures.
After attempting to quit, the non-menthol cigarette group had indications of delayed time to lapse (HR 0.82; 95% CI 0.55 to 1.22; p=0.33) and time to relapse (HR 0.67; 95% CI 0.42 to 1.06; p=0.09), although these were not statistically significant.
