Quantum-inspired optical coherence tomography using classical light in a single-photon counting regime.

Quantum optical coherence tomography (Q-OCT) presents many advantages over its classical counterpart, optical coherence tomography (OCT), provides an increased axial resolution, and is immune to even orders of dispersion. The core of Q-OCT is the quantum interference of negatively correlated entangled photon pairs which, in the Fourier domain, are observed by means of a joint spectrum measurement. In this work, we explore the use of a spectral approach in a novel configuration where classical light pulses are employed instead of entangled photons.

Analysis of the level of selected parameters of inflammation, circulating immune complexes, and related indicators (neutrophil/lymphocyte, platelet/lymphocyte, CRP/CIC) in patients with obstructive diseases.

Introduction: Chronic obstructive pulmonary disease (COPD) is an inflammatory disorder of the airways. An important element of COPD assessment is the evaluation of immune mechanisms involved in non-specific and specific response to ongoing inflammation.

Aim Of The Study: To evaluate the level of selected inflammatory and immunological parameters in patients with COPD, including C-reactive protein (CRP) and circulating immune complexes (CIC), as well as CRP/CIC index.

Comparison of temperature measurements in esophagus and urinary bladder in comatose patients after cardiac arrest undergoing mild therapeutic hypothermia.

Background: Mild therapeutic hypothermia (MTH) is a recommended method of treatment for comatose out-of-hospital cardiac arrest (OHCA) survivors. However, the proper site of temperature measurement in MTH is still not defined. The aim of this study was to compare temperature measurements in the esophagus and urinary bladder in comatose post-OHCA patients treated with MTH.

Determination of amino acids in urine of patients with prostate cancer and benign prostate growth.

Prostate cancer is the leading type of cancer diagnosed in men. Serum prostate-specific antigen levels and digital rectal exam are far from perfect when it comes to differentiation of patients with prostate cancer and benign prostatic hyperplasia. In this study, we attempt to determine whether amino acids can be used as prostate cancer biomarkers.

Unemployment in TB patients - ten-year observation at regional center of pulmonology in Bydgoszcz, Poland.

Background: Tuberculosis (TB) affects the poorest of the poor and is an example of a disease that can contribute to the "disease-poverty trap". The variable epidemiological situation is associated with social risk factors, such as unemployment, which may favor the occurrence of this disease. The aim of this study was to analyze unemployment as a factor that can influence the incidence and course of the disease.

Alcoholism and other socio-demographic risk factors for adverse TB-drug reactions and unsuccessful tuberculosis treatment - data from ten years' observation at the Regional Centre of Pulmonology, Bydgoszcz, Poland.

Background: Tuberculosis (TB) is one of the most dangerous infectious diseases and has one of the highest mortality rates. For decades a strong association has been evident between certain socio-economic factors and TB adverse events and failure of treatment, yet there is a limited quantity of literature available on this subject, especially in the Polish literature.

Material And Methods: We examined epidemiological data from 2025 TB patients treated at the Regional Centre of Pulmonology in Bydgoszcz, Poland between 2001 and 2010.

[The analysis of smoking tobacco of patients with tuberculosis--data from ten years observation in Regional Center of Pulmonology in Bydgoszcz].

Unlabelled: Tobacco smoking is recognised by the society as the the main problem of the public health in the world and as the factor of the risk of tuberculosis, it grew up last decades considerably, universally particularly in countries developing. That is why also our studies also represents in the clinical aspect the relationship between tuberculosis - as active disease and tobacco smoking.

The Method: The retrospective investigation comprised 2025 patients with tuberculosis in the period 10 years from Regional Center of Pulmonology in Bydgoszcz.

[Molecular diagnostic tests for thrombophilia in patients referred to genetic counseling clinic because due to recurrent pregnancy failure. One center's experience].

Unlabelled: The loss of three or more subsequent pregnancies before the end of the 22nd week is observed in 0.4-1% of women. Despite great advances in medicine, the causes of pregnancy failure (miscarriages, missed abortions and stillbirths), and the birth of a child or children with congenital abnormalities, are still not determined precisely

The Aim: The purpose of the research was to determine the association of polymorphisms and mutations of coagulation factors II and V genes, as well as methylenetethrahydrofolate reductase (MTHFR) gene polymorphism, with the course of pregnancy and the type of reproductive failure.
