Heterozygous Family Hyperlipidemia within a Martial artist Aviator.
A wide range of therapeutic regimens, including single-inhaler triple therapies (SITTs), are now available for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Thus, an improved understanding of patient preferences may be valuable to inform physician prescribing decisions. This study was performed to assess the factors considered by patients when making decisions about their COPD treatments using qualitative techniques.

In the United Kingdom, United States and Germany, individual qualitative interviews (n=10 per country) and focus groups (1 per country; [United Kingdom, n=4; United States, n=6; Germany, n=6 participants]) were conducted. Interviews and focus groups were semi‑structured, lasting approximately 60 minutes, and focused on treatment preferences. Data were analyzed according to emerging themes identified from the interviews; qualitative thematic analysis of the data was performed using specialist software.

In interviews and focus groups, efficacy, ease of use, and lower frequency of use were favored attributes for current treatment, while side effects, medication taste, and more complex administration techniques were key dislikes. In interviews, most participants would consider a switch in medication, mainly for improved efficacy, but also to reduce medication frequency or following physician advice. Overall, efficacy and ease of use were the 2 most important attributes reported in interviews in all 3 countries.

Patients with COPD have preferences for certain attributes of medication, highlighting the multi-faceted nature of treatment effectiveness and the importance of the delivery device.These results were subsequently used to inform the design of a discrete choice experiment.

Alpha-1 antitrypsin deficiency (AATD) is caused by genetic variants in the
gene conferring risk of developing emphysema. The clinical expression of AATD-related emphysema mostly occurs in carriers of 2 deficient alleles. By DNA sequencing of
, numerous rare variants have been identified. Clarifying whether 2 mutations observed in 1 patient are on the same or distinct alleles has obvious clinical implications.

We studied 7 carriers of a rare variant, Leu353Phe_fsTer24, known to lead to undetectable serum levels of AAT. Two of them were also carriers of the S or Z allele. We developed an allele-specific DNA sequencing method to characterize the allelic background of the Leu353Phe_fsTer24 variant.

The Leu353Phe_fsTer24 variant was transmitted on the same allele as the M3 variant (E376D) in all patients. This mutation is thus named Q0
on the conventional PI system. We demonstrated that individuals harboring the E264V (S) and E342K (Z) mutations had them on distinct alleles from Q0
and are, thus, compound heterozygotes. The 7 Q0
carriers had AAT levels ranging from 0.18g/l to 0.82g/l. The lowest AAT serum levels were observed in compound heterozygotes (S/Q0
and Z/Q0
) suggesting higher risk of developing emphysema.

For the 7 patients, Leu353Phe_fsTer24 is transmitted on the M3 background and they are, thus, carriers of the Q0
allele. Allele-specific DNA sequencing was useful to distinguish 1 or 2 deficient alleles in carriers of 2 mutations. In rare cases, this method is important to understand the clinical significance of genetic variants found in

Classical frequentist statistics, including null-hypothesis significance testing (NHST), dominates nursing and medical research analysis. However, there is increasing recognition that null-hypothesis Bayesian testing (NHBT) merits inclusion in healthcare research analysis.

To recommend that researchers complement the P-value from NHST with a Bayes factor from NHBT in their research analysis.

Reporting the P-value and a Bayes factor clarifies results that may be difficult to interpret using the P-value alone.

NHBT offers statistical and practical advantages that complement NHST.

The application of near-infrared spectroscopy (NIRS) to determine the concentrations of tissue chromophores has typically relied on three alternative technological approaches continuous-wave, frequency-domain, and time-domain. It is often the case that uncertain and variable coupling of light into and out of the skin surface renders absolute measurements unreliable, and NIRS methods are mostly used to measure changes of chromophore concentrations and of physiological parameters such as blood volume and oxygenation.

The aim has been to investigate whether an approach based on a wavelength-modulated source may enable measurements to be acquired, which are independent of surface coupling and may facilitate derivation of absolute values of tissue parameters.

An analysis is performed using the modified Beer-Lambert law.

It is shown that the relative modulation in detected intensity resulting from a wavelength-modulated source could be used to estimate absolute concentrations of chromophores if unknown surface coupling losses and geometrical factors are insensitive to small changes in wavelength.

Wavelength modulated NIRS could be an effective tool for quantitative in vivo analysis of tissues, although it may be technically challenging.

To investigate the value of optic disc retinal nerve fiber layer (RNFL) thickness in the diagnosis of diabetic peripheral neuropathy (DPN).

Ninety patients with type 2 diabetes, including 60 patients without DPN (NDPN group) and 30 patients with DPN (DPN group), and 30 healthy participants (normal group) were enrolled. Optical coherence tomography (OCT) was used to measure the four quadrants and the overall average RNFL thickness of the optic disc. The receiver operator characteristic curve was drawn and the area under the curve (AUC) was calculated to evaluate the diagnostic value of RNFL thickness in the optic disc area for DPN.

The RNFL thickness of the DPN group was thinner than those of the normal and NDPN groups in the overall average ((101.07± 12.40) µm vs. (111.07±6.99) µm and (109.25±6.90) µm), superior quadrant ((123.00±19.04) µm vs. (138.93±14.16) µm and (134.47±14.34) µm), and inferior quadrant ((129.37±17.50) µm vs. (143.60±12.22) µm and (144.48±14.10) µm), and the differences were statistically significant.
