One of the most evaluated eye tracking tasks in schizophrenia (SZ) and bipolar disorder (BD) are smooth pursuit eye movements. They rely on the maintenance of slowly moving object on the fovea. While most of the studies evaluated tracking of a target that moves in the fronto-parallel plane, only two assessed vergence eye movements (VEM), which relies on the pursuit of object that moves in depth. The aim of our study was to compare VEM performance in SZ and BD. We evaluated 28 SZ patients, 32 BD patients and 25 healthy controls (HC). Participants underwent thorough optometric examination before eye tracking task. VEM were measured with the use of infrared eye tracker and dedicated vergence stimuli generator. SZ patients showed higher mean break and recovery points of fusion and shorter correct tracking time than HC. BD individuals revealed tracking accuracy deficits and higher number of saccades than HC. Compared to BD, SZ patients showed decrease of maximal convergence and divergence. Moreover, they presented tracking accuracy deficits of non-dominant eye: altered eyes positioning error during convergence and divergence gain. Exploratory analysis revealed significant gender differences between groups in terms of binocular VEM parameters. In this study we have recognized pattern of eye movement disturbances differentiating abovementioned groups. SZ patients showed decreased vergence tracking range with shorter tracking time and impaired accuracy of non-dominant eye, while BD patients showed higher number of saccades with decreased tracking accuracy. Neuroimaging studies are necessary to identify neuronal underpinnings of VEM impairments in SZ and BD.

Związki wyznaniowe w Polsce mogą być finansowane m.in. poprzez przekazywanie na ich rzecz darowizn. Darczyńca z tytułu dokonania darowizny może skorzystać z ulgi podatkowej. W sposób szczególny darczyńca może skorzystać z ulgi podatkowej z tytułu dokonania darowizny na kościelną działalność charytatywno-opiekuńczą prowadzoną przez kościelne osoby prawne. Podstawę normatywną tej ulgi podatkowej stanowią właściwe przepisy ustaw, które regulują sytuację prawną poszczególnych związków wyznaniowych, a nie ustawy podatkowe. Jednak przepisy wskazanych ustaw możliwość skorzystania z tej ulgi podatkowej uzależniają od spełnienia kilku warunków. Kościelna osoba prawna, na rzecz której dokonano darowizny, powinna wystawić darczyńcy pokwitowanie odbioru darowanej kwoty oraz w ciągu dwóch lat od jej uzyskania jest zobowiązana złożyć sprawozdanie z przeznaczenia wskazanej kwoty na działalność charytatywno-opiekuńczą. Ponadto, zgodnie z przepisami podatkowymi, potwierdzeniem wysokości darowanej kwoty powinien być dowód wpłaty darowizny na rachunek bankowy osoby obdarowanej. W praktyce spełnienie wskazanych warunków wywołuje wiele trudności. Świadczy o tym bogate orzecznictwo Naczelnego Sądu Administracyjnego, zwłaszcza dotyczące zagadnienia sprawozdania z przeznaczenia darowizny na działalność charytatywno-opiekuńczą kościelnej osoby prawnej. Naczelny Sąd Administracyjny w swoim orzecznictwie doprecyzowuje pojęcie sprawozdania z przeznaczenia darowizny na działalność charytatywno-opiekuńczą kościelnej osoby prawnej. Jednak, jak pokazuje praktyka, wyjaśnienia te są nadal niewystarczające. Religious organizations in Poland can be financed through donations. The donor may benefit from a tax relief for making a donation. In a special way, the donor may benefit from a tax relief for making a donation for church charity and welfare activities conducted by church legal entities. The normative basis for this kind of tax reliefs are the laws on the relation between the state and individual religious organizations, and not tax laws. However, according to the provisions, several conditions have to be fulfilled for the tax relief in question to be claimed. A church legal entity to which a donation has been made shall issue a receipt to the donor and shall submit a report on the use of the donation for charitable and protective purposes within two years of receiving a donation. In addition, according to the tax regulations, the amount of a donation should be confirmed by a relevant bank statement. In practice, the fulfilment of these conditions gives rise to many difficulties. This is evidenced by the rich case law of the Supreme Administrative Court, especially regarding the question of a report on spending a given donation on church charity and welfare activities. The case law of Supreme Administrative Court clarifies the concept of the report under discussion. However, as the practice has shown, it seems that these explanations are still insufficient.

Cel pracyW odniesieniu do choroby afektywnej dwubiegunowej (ChAD), dotychczasowe prace wskazują na zaburzenia ruchów sakadycznych, głównie pod postacią wydłużenia czasu reakcji (latencji) w testach prosakad i antysakad. Dotychczas nie przeprowadzono oceny ruchów wergencyjnych gałek ocznych u osób z ChAD. Głównym celem naszego badania jest ocena parametrów konwergencji (zbieżne ruchy gałek ocznych) w tej grupie klinicznej.MetodaDo badania włączono 30 pacjentów z ChAD w stanie remisji objawowej i 23 zdrowych ochotników. Uczestników poddano badaniu optometrycznemu oceniającemu punkt bliski konwergencji przy użyciu pręta fiksacyjnego. Badanie okulometryczne przeprowadzono przy pomocy okulografu wykorzystującego promieniowanie podczerwone z dedykowanym stymulatorem wergencji.WynikiPacjenci z ChAD wykazali istotnie większy średni błąd pozycji konwergencji do celu oraz większą liczbę wtrąceń sakadycznych w porównaniu do grupy kontrolnej. Analiza składowych głównych przeprowadzona na zmiennych okulometrycznych pokazała istotne różnice między pacjentami z ChAD a zdrowymi ochotnikami. Wykazano obecność istotnych korelacji między zaburzeniami ruchów wergencyjnych a liczbą wtrąceń sakadycznych.WnioskiPacjenci z ChAD ujawnili zaburzenia ruchów wergencyjnych gałek ocznych podobne do zaburzeń opisywanych w trakcie śledzenia bodźców poruszających się w płaszczyźnie czołowej. Podczas gdy zaburzenia wergencji były opisywane w innych zaburzeniach psychicznych, nasza praca po raz pierwszy obiektywnie zmierzyła to zjawisko w ChAD.

The aim of this chapter is to discuss the level of guarantee of religious freedom of prisoners, both in historical and legal perspective. The answer to the question of whether believers of different religions have similar access to religious services and similarly guaranteed right to practise their own religion, e.g. religiously motivated diet, has fundamental importance. The analysis of prisoners’ right to practise their own religion was conducted with regard to the constitutional principle of equality of rights of churches and other religious denominations, including the practice of their application.

Purpose The aim of the study was to analyze sonographic (US) renal findings in lithium-treated bipolar patients and to correlate them with renal function. Methods Renal US and renal function tests were performed on 120 patients with bipolar disorder. Ninety patients (30 males, 60 females), aged 36–82 years, had received lithium therapy for an average of 16 years, whereas 30 patients (10 males, 20 females), aged 35–85 years, who had never been exposed to lithium, served as controls. Results In the lithium-treated group, patients with macrocysts (22%) had poorer renal function with higher creatinine serum concentrations, lower estimated glomerular filtration rates, and lower urine specific gravity, compared with the patients without macrocysts. The US changes characteristic for lithium nephropathy (punctate hyperechoic foci, microcysts < 2 mm, and increased echogenicity) were seen in three patients. These patients had been treated with lithium for more than 20 years and had impaired renal function. Sixteen percent of patients in the control group had macrocysts; however, no correlation between their presence and impaired renal function was found. Conclusions The presence of macrocysts in the kidneys of lithium-treated bipolar patients is associated with impaired renal function. The US changes characteristic for lithium nephropathy are rare, and in our study, were only found in patients treated with lithium for 20 years or more. © 2016 Wiley Periodicals, Inc.

The principle of equal rights of religious communities is often taken issue in the jurisprudence of the Constitutional Court. It has been dealt with in the article. 25 paragraph 1. 1 of the Constitution of 2 April 1997. It is the hallmark for democratic secular States. It Guarantees respect for religious diversity and the world view of society. The basis of this principle is human dignity. The Constitutional Court has confirmed in its case-law that the right premise equal rights of churches and other religious communities should be defined a common feature. Therefore, equal rights of religious communities is equal treatment of operators of a specific feature in the same degree. As a consequence of the existence of this principle in the Polish legal system is to exclude the possibility of State religion, because the nexus one would be in the form of a privileged position ' religious association of the Church of the State. At the same time, this principle implies different treatment churches and religious communities, which do not have the common feature important. The current Constitution of 2 April 1997 introduces its content the principle of equality of religious communities as one of the many constitutional instantiation of the principle of equality. This position highlighted by the Constitutional Court in its judgment of 2 April 2003 (K 13/02), and then also repeated in its judgment of 14 December 2009. Therefore, the principle of equality of religious communities should be interpreted as a general principle of equality with regard to the whole of the acquis the jurisprudence of the Constitutional Court regarding the constitutional principle of equality. This indicates a single line of the jurisprudence in the interpretation of this principle.

In Poland, the right to organise lessons of religion in public kindergartens and schools belongs to religious organisations that have a definite legal status. This right stems from the right of parents to raise their children in accordance with their world view that may happen to be of religious character. Evidently, the exercise of the said right must be compliant with the constitutional principle of equality of religious organisations. The some proponents of the doctrine of law on religion call into question the compliance of particular legal solutions with the principle of equality with regard to teaching of religion in public schools. These solutions will include: description of qualifications of religion teachers, the development of curricula for religious instruction, limits as to the number of students for religion lessons to take place, and the right to exempt students from regular classes to take part in a retreat. Our analysis of the legal solutions relating to the right to arrange teaching of religion at public schools by religious organisations permits a conclusion that they are in conformity with the constitutional principle of equality of such entities.

Objectives We assessed kidney function in long-term lithium-treated bipolar patients compared with age-matched patients not taking lithium, including novel markers of kidney injury such as plasma neutrophil gelatinase-associated lipocalin (NGAL) and urinary beta-2 microglobulin (β2-MG) Methods The study comprised 120 patients with bipolar disorder of which 90 (30 males and 60 females) have been receiving lithium for 5–38 (mean 16) years, and 30 (10 males and 20 females) have never been exposed to lithium. Results Lithium-treated patients, both men and women, showed significantly higher plasma NGAL and urinary β2-MG and lower urine specific gravity and estimated glomerular filtration rate (eGFR), compared with patients not taking lithium. In these patients, serum NGAL did not correlate with any clinical feature or other parameter of kidney function. Urinary β2-MG correlated with serum creatinine and eGFR in the whole group of lithium-treated patients and in addition, in males, with duration of illness, duration of lithium treatment, and urine specific gravity. Conclusions Lithium treatment causes an impairment of kidney function reflected also by abnormal levels of novel markers of kidney injury. Of these, urinary β2-MG, as a marker of tubular function seems to be better predictor than serum NGAL in lithium-treated patients because it shows multiple clinical and biochemical correlations, especially in men.

Background Concerns about potential adverse effects of long-term exposure to lithium as a mood-stabilizing treatment notably include altered renal function. However, the incidence of severe renal dysfunction; rate of decline over time; effects of lithium dose, serum concentration, and duration of treatment; relative effects of lithium exposure vs. aging; and contributions of sex and other factors all remain unclear. Methods Accordingly, we acquired data from 12 collaborating international sites and 312 bipolar disorder patients (6142 person-years, 2669 assays) treated with lithium carbonate for 8–48 (mean 18) years and aged 20–89 (mean 56) years. We evaluated changes of estimated glomerular filtration rate (eGFR) as well as serum creatinine, urea–nitrogen, and glucose concentrations, white blood cell count, and body-mass index, and tested associations of eGFR with selected factors, using standard bivariate contrasts and regression modeling. Results Overall, 29.5% of subjects experienced at least one low value of eGFR ( 55; risk of ≥2 low values was 18.1%; none experienced end-stage renal failure. eGFR declined by 0.71%/year of age and 0.92%/year of treatment, both by 19% more among women than men. Mean serum creatinine increased from 0.87 to 1.17 mg/dL, BUN from 23.7 to 33.1 mg/dL, glucose from 88 to 122 mg/dL, and BMI from 25.9 to 26.6 kg/m2. By multivariate regression, risk factors for declining eGFR ranked: longer lithium treatment, lower lithium dose, higher serum lithium concentration, older age, and medical comorbidity. Later low eGFR was also predicted by lower initial eGFR, and starting lithium at age ≥ 40 years. Limitations Control data for age-matched subjects not exposed to lithium were lacking. Conclusions Long-term lithium treatment was associated with gradual decline of renal functioning (eGFR) by about 30% more than that was associated with aging alone. Risk of subnormal eGFR was from 18.1% (≥2 low values) to 29.5% (≥1 low value), requiring about 30 years of exposure. Additional risk factors for low eGFR were higher serum lithium level, longer lithium treatment, lower initial eGFR, and medical comorbidity, as well as older age.

We present the cases of five patients (two men aged 64 years and 79 years) and three women (aged 64 years, 65 years and 75 years) who have received lithium treatment for 40–45 years, with particular regard to kidney and thyroid functions, hypercalcaemia and cognition, in the context of disease course and overall functioning. Lithium was initiated in the early phase of the illness (in three patients within the first 2 years). In four patients, lithium concentration was between 0.60 and 0.65 mmol/l and in one patient, between 0.7 and 0.8 mmol/l. Four were very good lithium responders. One man had stage 3 chronic kidney disease, and the other stage 2/3 chronic kidney disease. All three women had asymptomatic stage 2 chronic kidney disease. One woman had severe thyroid dysfunction (Hashimoto’s disease) with extremely high levels of antithyroid peroxidase antibodies and antithyroglobulin antibodies and was receiving thyroxine. Serum calcium levels were normal or borderline in all five patients, and most cognitive functions were comparable to healthy persons of similar gender, age and years of education. All the patients were professionally active until 55–65 years and their family and social functioning were satisfactory. It was concluded that, in good lithium responders, ultra-long-term treatment with lithium enables good professional and psychosocial functioning, and the possible somatic side effects are manageable.

According to the current law religious denominations in Poland may exercise their rights in accordance with the principle of equality regardless of the form in which their legal status is regulated. The catalogue of rights that religious denominations are entitled to include the right to proceeding with concluding the marriage in accordance with the internal law of religious denominations which after the fulfilment of additional criteria will have civil effects. Using this law should be consistent with the constitutional principle of equality of religious denominations. In the current law only those religious denominations are entitled to this right, whose legal status is regulated on the basis of an international agreement or a separate law . This eliminates the possibility of applying for the right religious denominations whose legal existence is based on the entry into the Register of Churches and other religious denominations. Differentiation of these entities based on the only criterion, which is the form of their legal status regulation raises doubts as to its compatibility with the indicated constitutional principle of equality. Regardless of the form of legal status regulation any religious denomination, in accordance with the principle of equality, should be able to exercise right which another religious denomination is entitled to. In case if there are justifiable reasons the legal position of religious communities may be made differentiated. It should be emphasized that the form itself of regulation of religious denomination is not a sufficient criterion for introduction differentiation of the of the legal status of religious denominations. Therefore, it is necessary to change the law in order to ensure the implementation of the constitutional principle of equality of religious denominations also within the right to use the religious form of civil marriage contraction.

Począwszy od roku 1963 stosowanie litu stanowi najbardziej udokumentowany sposób postępowania długoterminowego w chorobie afektywnej dwubiegunowej (ChAD), zarówno dla zapobiegania epizodom depresyjnym, jak i maniakalnym, a także zmniejszania ryzyka samobójstwa. W ChAD czynność gruczołu tarczowego i osi podwzgórze-przysadka-tarczyca (PPT) ma istotne znaczenie dla patofizjologii, przebiegu klinicznego i leczenia tej choroby. Wpływ litu na gruczoł tarczowy stanowi jedno z najważniejszych działań niepożądanych długotrwałej terapii tym lekiem. Lit jest gromadzony w tarczycy w stężeniu 3 do 4 razy większym niż w osoczu, a w wyniku jego stosowania dochodzi do zmniejszenia produkcji i hamowania uwalniania hormonów tarczycy oraz zmian w procesach immunologicznych dotyczących tego gruczołu. Najczęstszymi objawami ubocznymi związanymi z działaniem długotrwałego stosowania litu na tarczycę jest wole i niedoczynność tarczycy. Rzadkim powikłaniem stosowania litu jest nadczynność tarczycy. Lit może też powodować wzrost autoimmunizacji tarczycy, zwłaszcza, jeśli jest ona obecna przed rozpoczęciem leczenia oraz zmiany strukturalne tego gruczołu. W artykule omówiono również postępowanie w opisanych wyżej powikłaniach oraz zasady monitorowania czynności tarczycy u osób otrzymujących długotrwałą terapię litem.

Objectives An important side effect of lithium therapy is an influence on thyroid function. It is unclear whether there is a significant association between thyroid function and duration of lithium administration. The aim of the present cross-sectional study was to measure levels of thyroid hormones and antibodies in patients with bipolar disorder receiving lithium for more than ten years. Methods The study was performed in 66 patients (21 males, 45 females) with bipolar mood disorder, receiving lithium for 10–44 (21 ± 9; mean ± standard deviation) years. Thyroid-stimulating hormone (TSH), free thyroxine (fT3), and free triiodothyronine (fT4) were measured by the microparticle enzyme immunoassay. Thyroid peroxidase (TPO) antibodies, thyroglobulin (TG) antibodies, and TSH receptor (TSH-R) antibodies were measured by the radioimmunoassay. Results Some features of hypothyroidism were found in ten (22%) female patients (seven received levothyroxine and three had increased TSH). No abnormality in thyroid hormones was found in male patients. A significant percentage of patients had abnormally high levels of anti-TPO, and anti-TG antibodies, which correlated with TSH and fT3 concentrations. There were no differences in thyroid function between patients receiving lithium for 10–20 years and those taking the drug for more than 20 years. Conclusions These results confirm the greater susceptibility of female subjects for disturbances of thyroid hormones during lithium therapy, with one-fifth of them showing some features of hypothyroidism. Abnormally high levels of anti-TPO and anti-TG antibodies were shown in a significant proportion of patients. However, in contrast to the effect of lithium on kidney function, our results do not show an association between the duration of lithium therapy and thyroid dysfunction.

We assessed kidney function in long-term lithium-treated bipolar patients compared with age-matched patients not taking lithium, including novel markers of kidney injury such as plasma neutrophil gelatinase-associated lipocalin (NGAL) and urinary beta-2 microglobulin (β2-MG) METHODS: The study comprised 120 patients with bipolar disorder of which 90 (30 males and 60 females) have been receiving lithium for 5-38 (mean 16) years, and 30 (10 males and 20 females) have never been exposed to lithium.Lithium-treated patients, both men and women, showed significantly higher plasma NGAL and urinary β2-MG and lower urine specific gravity and estimated glomerular filtration rate (eGFR), compared with patients not taking lithium. In these patients, serum NGAL did not correlate with any clinical feature or other parameter of kidney function. Urinary β2-MG correlated with serum creatinine and eGFR in the whole group of lithium-treated patients and in addition, in males, with duration of illness, duration of lithium treatment, and urine specific gravity.Lithium treatment causes an impairment of kidney function reflected also by abnormal levels of novel markers of kidney injury. Of these, urinary β2-MG, as a marker of tubular function seems to be better predictor than serum NGAL in lithium-treated patients because it shows multiple clinical and biochemical correlations, especially in men.

Long-term mood instability and fluctuations in mood are quintessential features of bipolar disorder; however a great majority of of mood rating scales are cross-sectional and focused on acute symptoms. NIMH Life Chart Methodology (NIMH-LCM) and ChronoRecord program on the contrary record the severity, duration and frequency of mood swings. Many bipolar patients need combined treatment and take multiple medications, which is associated with better treatment outcome but also with the increased risk of side effects. Treatment with drug combination negatively impacts the compliance of the patients. Simultaneous assessment of daily mood fluctuations and monitoring of life events and medications may help to optimize treatment and to better detect nuances of partial response. TacyJakJa.pl an Internet site, in which patients keep on-line diaries concerning their course of disease and treatment, makes this tool available to a large number of patients. Not only does it enable the patients to learn about mood disorders, but also it increases their involvement in their treatment.

Summary Background Lithium is the most effective therapeutic modality for the prevention of recurrences in bipolar disorder. An important adverse effect of lithium, especially with long-term treatment, is a possibility of a toxic effect on kidney function. Therefore, the aim of the study was to assess kidney function in a group of long-term lithium-treated patients. Material/Methods The study comprised 80 patients with bipolar mood disorder (26 male, 54 female), aged 60±11 years. They had been receiving lithium for 5–38 (16±9) years. Random urine sample was examined for albumin and creatinine excretion, and urinary albumin to creatinine ratio (UACR) was calculated. Specific gravity of the urine sample was recorded. Serum concentration of creatinine was measured and estimated glomerular filtration rate (eGFR) was calculated. Serum concentration of albumin was also measured. Results Decreased eGFR values 30 mg/g) were found in 25% of men and 12% of women, respectively. Serum albumin concentration >52 g/l was detected in 19% of patients (17% of men and 20% of women). Specific gravity of the urine, equal to or below 1.005, was recorded in 21% of men and 14% of women. Conclusions The results confirm the opinion that screening for the markers of kidney damage should be performed in long-term lithium-treated patients for identification of persons with impaired kidney function. Male sex seems to be the risk factor for the development of kidney damage during long-term lithium treatment.

Background Most bipolar patients experience a reduction in urinary concentrating ability within a few weeks of starting lithium treatment. This phenomenon may be connected with the effect of lithium on the glycogen synthase kinase-3beta (GSK-3β) present in the renal tubules. The GSK-3β gene is located on chromosome 3q13 and possesses a functional -50 C/T polymorphism. In the present study, we estimated this polymorphism in a group of long-term lithium-treated patients and assessed its association with various parameters of kidney function, including novel markers of kidney injury such as serum neutrophil gelatinase-associated lipocalin (NGAL) and urinary beta2-microglobulin (β2-MG). Methods The study comprised 78 patients with bipolar mood disorder (25 males, 53 females), aged 36 to 82 (60 ± 11) years. The mean duration of bipolar illness was 6 to 50 (24 ± 10) years, and the patients have been receiving lithium for 5 to 38 (16 ± 9) years. All the patients had the following features, regarded as the phenotypes of kidney functions measured: urine examination for specific gravity evaluation, serum creatinine concentration, and estimated glomerular filtration rate (eGFR) evaluation, as well as the serum concentrations of NGAL and urinary β2-MG. Genotyping of GSK-3β gene -50 C/T polymorphism was done by polymerase chain reaction analysis. Results and discussion Thirty-four patients (6 males, 28 females) had the T/T genotype, 37 patients (16 males, 21 females) had the T/C genotype, and 7 patients (3 males, 4 females) had the C/C genotype. Patients homozygous for C allele had significantly higher urine specific gravities (1.019 ± 0.008) compared to the remaining genotypes (1.013 ± 0.007) (p = 0.035), with no influence of the duration of lithium treatment. Other parameters of kidney function (serum creatinine, eGFR, serum NGAL, and urinary β2-MG levels) were not different between genotypes and, again, were not affected by the duration of lithium treatment. There was no correlation between urine specific gravity and other kidney function parameters. The results of our study indicate that the GSK-3β genotype may be connected with lithium-induced impairment of renal concentrating ability in long-term lithium-treated bipolar patients. Limitations of the study include small size of the sample, small number of C/C genotype patients, and a lack of multiple testing analysis of genotypic differences in various measures of kidney function.
