Comparison of Benthos Diatoms Communities in the Spring and Estuary Sections of the Lucigia River
Diatoms communities in the Luciąża River identified
in two observation stations and, namely, in the station 2 located
in the village of Cieszancwice (spring section) and in the station
9 in the village of Przygłów (river estuary section) were compared
by means of the rank correlation method and Marczewski and
Steinhaus coefficient of similarities. There were also compared
diatoms communities in different periods in the same stations.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę

An attempt at determining the dependence between the number of dead or alive diatom cells and the season or water temperature
Sampling was done in one site established in the Luciąża River on for
occasions over the annual cycle. Observation data are presented in contingency tables,
and their significance tested with the χ² test. Results obtained testify to the dependence
of the numbers of dead and alive cells first of all on season, and also on water
temperature.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę
Morphological diversity of Pediastrum boryanum (Turp.) Menegh. and P. duplex Meyer in samples from Pond Okręt
Results of observing morphological diversity of P. boryanum and
P. duplex occurring in samples from Pond Okręt are presented. The same teratological
forms that were collected in the water body in 1968-1969 continued to inhabit it
also after over a dozen years, in 1984-1987.Zadanie pt.

Clinical course and outcome of SARS-CoV-2 infection in multiple sclerosis patients treated with disease-modifying therapies — the Polish experience
Introduction. The aim of this study was to report the course and outcome of SARS-CoV-2 infection in multiple sclerosis (MS) patients treated with disease-modifying therapies (DMTs) in Poland. A major concern for neurologists worldwide is the course and outcome of SARS-CoV-2 infection in patients with MS treated with different DMTs. Although initial studies do not suggest an unfavourable course of infection in this group of patients, the data is limited.Materials and methods. This study included 396 MS patients treated with DMTs and confirmed SARS-CoV-2 infection from 28 Polish MS centres. Information concerning patient demographics, comorbidities, clinical course of MS, current DMT use, as well as symptoms of SARS-CoV-2 infection, need for pharmacotherapy, oxygen therapy, and/or hospitalisation, and short-term outcomes was collected up to 30 January 2021. Additional data about COVID-19 cases in the general population in Poland was obtained from official reports of the Polish Ministry of Health.Results. There were 114 males (28.8%) and 282 females (71.2%). The median age was 39 years (IQR 13). The great majority of patients with MS exhibited relapsing-remitting course (372 patients; 93.9%). The median EDSS was 2 (SD 1.38), and the mean disease duration was 8.95 (IQR 8) years. Most of the MS patients were treated with dimethyl fumarate (164; 41.41%). Other DMTs were less frequently used: interferon beta (82; 20.70%), glatiramer acetate (42; 10.60%), natalizumab (35;8.84%), teriflunomide (25; 6.31%), ocrelizumab (20; 5.05%), fingolimod (16; 4.04), cladribine (5; 1.26%), mitoxantrone (3; 0.76%), ozanimod (3; 0.76%), and alemtuzumab (1; 0.25%). The overall hospitalisation rate due to COVID-19 in the cohort was 6.81% (27 patients). Only one patient (0.3%) died due to SARS-CoV-2 infection, and three (0.76%) patients were treated with mechanical ventilation; 106 (26.8%) patients had at least one comorbid condition. There were no significant differences in the severity of SARS-CoV-2 infection regarding patient age, duration of the disease, degree of disability (EDSS), lymphocyte count, or type of DMT used.Conclusions and clinical implications. Most MS patients included in this study had a favourable course of SARS-CoV-2 infection. The hospitalisation rate and the mortality rate were not higher in the MS cohort compared to the general Polish population. Continued multicentre data collection is needed to increase the understanding of SARS-CoV-2 infection impact on the course of MS in patients treated with DMTs
Effect of sewage cleaning station in Piotrków Trybunalski on diatomic associations of the Strawa river
Praca powstała w wyniku badań porównawczych zbiorowiska okrzemek
rzeki Strawy, prowadzonych w latach 1974— 1975, przed i po uruchomieniu
oczyszczalni ścieków w Piotrkowie Trybunalskim.
Zamieszczono spis gatunków okrzemek oraz tabelę przedstawiającą ogólną
liczbę jednostek taksonomicznych, w której podano również ich skład
ilościowy w 1 ml mikrobentosu.
Zbiorowiska okrzemek w badanych okresach porównano metodą korelacji
rang.This study was aimed at analysis of association of bentos diatoms of the Strawa
river, at a stand in Przygłów, in 1974 (before establishment of the sewage cleaning
station in Piotrków Trybunalski) and in 1975 (after establishment of the station).
Results of physico-chemical studies of the water of the Strawa river are reported.
In general, 237 taxons of diatoms were determined. Associations were compared by
the rank correlation method after Kadłubowska.
Within the period of investigations, no changes in the water purity class and
in the diatomic associations of the Strawa river were found.Zadanie pt.

Symptoms after COVID-19 infection in individuals with multiple sclerosis in Poland
(1) Background: To report and analyze the presence of residual symptoms after SARS-CoV-2 infection among Polish patients with multiple sclerosis (MS) treated with different disease-modifying therapies (DMTs). (2) Methods: The study included 426 individuals with MS treated with DMTs and confirmed SARS-CoV-2 infection from 12 Polish MS centers. The data were collected through to 31 May 2021. The information included demographics, specific MS characteristics, course of SARS-CoV-2 infection, and residual (general and neurological) symptoms lasting more than four and 12 weeks after the initial infection. The results were obtained using maximum likelihood estimates for odds ratio and logistic regression. (3) Results: A total of 44.84% patients with MS reported symptoms lasting between four and 12 weeks after the initial infection; 24.41% people had symptoms that resolved up to 12 weeks, and 20.42% patients had symptoms that lasted over 12 weeks. The most common symptoms were: fatigue, disturbance of concentration, attention, and memory, cognitive complaints, and headache. None of the DMTs were predisposed to the development of residual symptoms after the initial infection. A total of 11.97% of patients had relapse three months prior or after SARS-CoV-2 infection. (4) Conclusion: Almost half of individuals with MS treated with different DMTs had residual symptoms after SARS-CoV-2 infection. None of the DMTs raised the probability of developing post-acute COVID symptoms
