Diagnosis of channelopathies affects quality of life and psychological status in patients and relatives

Background

Cardiac channelopathies are a group of inherited cardiovascular diseases with increased risk of sudden cardiac death in structurally normal hearts. The psychological status after their diagnosis has not been thoroughly studied.

Purpose

To establish health-related quality of life (QOL) and emotional response to the diagnosis of channelopathies in a cohort of patients and their families.

Methods

Adult patients with diagnosis of channelopathies and their relatives were eligible. After enrolment they were divided in 3 groups, according to the time of psychological evaluation: At diagnosis (T0), one year (T1), and 2 years after diagnosis (T2). Psychological evaluation was conducted through self-report questionnaires on QOL (SF-12), general anxiety (BAI), depression (BDI-II), perceived stress (PSS-10), post-traumatic stress (IES-R), and protective resilience resources (RSA).

Results

From August 2020 to April 2021, 64 patients (95% Brugada syndrome, 3% long QT syndrome, and 2% catecholaminergic polymorphic ventricular tachycardia) and 41 relatives were enrolled. A control group of 105 healthy subjects, matched to the study group regarding age, gender and level of education, was also enrolled.

Patients at T0 showed increased physical and reduced mental QOL; at T1, reduction of RSA; and at T2, reduction of RSA and increased BAI. A significant percentage of patients referred the occurrence of a traumatic event during their lifetime at T0, T1 and T2 (Figure 1). At T0 relatives presented high PSS-10 and a high proportion of them reported experiencing a traumatic episode during their lifetime. BAI score was high among relatives at T0, T1 and T2, reaching levels of concern 2 years after the diagnosis (Figure 2). Female gender independently predicted MCS-12 in patients at T0.

Conclusions

Diagnosis of channelopathies impact different areas of QOL and the psychological sphere in patients (QOL, resilience, anxiety and occurrence of traumatic events during lifetime) and relatives (anxiety, stress, and occurrence of traumatic events during lifetime), and at different moments after the diagnosis. Female gender was an independent predictor of worse mental QOL in patients at T0. Patients and their families should be involved in psychological counselling and psychoeducational interventions, taking into account their differences and the timing of psychological responses, in order to better support them in adjusting to their new life circumstances.

Effects of COVID-19 pandemic on cardiac surgery and practice. Did we hit the mark: strategy or casuality?

Background

COVID-19 pandemic is having a collateral health effect on delivery of surgical therapies and reports from management and maintaining surgical care are little.

Purpose

Investigate the impact of COVID-19 in our cardiac surgical ward and practice by scoping review of the last two years of activity, between 1st March 2019 and 28th February 2021.

Methods

Our Hospital is a private institution accredited with the National Health Service with a global volume load of 750 cardiac cases per year.

We analized the pre-pandemic and the ongoing pandemic period on volume activity, the capacity of satisfying the needs of cardiosurgical patient and the mortality rate.

Results

We observed a minimal cardiac surgery caseload decline of 14.8%, probably due to environmental factor, the absence of E.D. in our institute, the rapid re-organization pathways, the hospital surveillance, the supply of personal protective equipment, the informative measures to improve patient and personnel welfare.

In order to enhance the pshycological impact of this devastating event, we invited all the health workers to fill a questionnaire regarding concerns and worries about the risk of transmitting the infection to their families or to aquire it themselves.

Conclusion

During this devastating pandemic the rapid response in re-organization pathways and hospital surveillance allowed us to preserve the cardiac surgery volume of life-saving and non deferrable cases.

Redescription of the male of Ixodes festai Rondelli, 1926 (Ixodida: Ixodidae) on specimens from Sardinia (Italy)

Ixodes festai Rondelli, 1926 is a poorly known bird parasite tick. Its immature forms have not been described yet, while the adult forms only insufficiently, especially the male. In this note the presence of the male of Ixodes festai for the first time in Sardinia (Italy) is reported and a detailed redescription is provided. Morphometric data as well as photographs performed both with optical and electron microscope (ESEM FEI Quanta 200) are also shown.

Spirocerca lupi isolated from gastric lesions in foxes (Vulpes vulpes) in Sicily (Italy)

Spirocerca lupi (Rudolphi 1809) is a cosmopolitan nematode of dogs and wild carnivores. In the past it has been reported in Italy, mainly in southern regions and in Sicily, where the parasite was observed in foxes in 2005. The parasite typically produces nodular masses in the oesophagus and thoracic aorta. During the 2003-2004 hunting season, the authors investigated a total of 55 foxes (Vulpes vulpes) hunted or killed by car accidents in the provinces of Palermo and Agrigento. All the foxes were subjected to necropsy and 6 (9.16%) had S. lupi nodules located exclusively in the gastric wall. The nature of the nodules was determined by opening them and detecting the nematodes inside, which were identified as S. lupi. Some of the nodules were characterized anatomopathologically and histopathologically. The formation of the parasitic nodule in the stomach only suggests a deviation from the route commonly followed by the nematode to reach the oesophagus, the elective anatomical site for completion of its lifecycle. This survey gives a contribution to the epidemiology of this parasite which is severely outdated in Italy and highlights some distinctive features of the life cycle and parasite migration.

Endothelin 1 in migraine and tension-type headache

We determined the plasma levels of ET1, both interictally and ictally, in 50 migraine patients, 20 with aura (MPA) and 30 without aura (MPWA), comparing them with the levels of 40 age-matched tension-type headache patients (20 episodic and 20 chronic) (ETTHP and CTTHP) and the levels of a group of 20 healthy control subjects (CS). No statistically significant difference was evident between the mean ET1 plasma levels of MPA and those of MPWA, assessed in headache-free periods. The mean ET1 plasma levels of MPA and MPWA, assessed interictally, were significantly higher than those of CS. However, the values of plasma ET1 in ETTP and in CTTHP did not differ statistically from those of CS. MPA and MPWA ET1 plasma levels increased significantly within 2 h from the onset of attacks (p < 0.0001) and remained significantly higher between 4 and 6 h from the onset. The ET1 plasma levels of ETTHP and CTTHP assessed during attacks did not differ statistically from those of the same patients assessed in the headache-free periods. The increase in ET1 levels in MPA and MPWA patients when assessed ictally, suggests that this peptide is involved in the haemodynamic changes and vascular tone modifications observed during migraine attacks, particularly in the first phase of the ictal period.

Neuropeptide Y in juvenile migraine and tension-type headache

Neuropeptide Y (NPY) is widely distributed throughout sympathetic nerve endings where it is co-stored and co-secreted with noradrenaline. It is considered a marker of noradrenergic function. To determine the role of NPY in the pathogenesis of juvenile headache, we determined its plasma levels in two groups of young migraine patients (with and without aura), in a group of episodic tension-type headache patients and in a group of age and sex-matched healthy subjects. Significantly lower plasma levels of NPY were evident in the migraine patients with aura (P < 0.001) and, to a lesser extent, in the migraine patients without aura (P < 0.02), both assessed in the interictal period, with respect to the control group. Plasma NPY levels tended to significantly increase during attacks in migraine patients with aura (P < 0.0009). A less evident, though significant increase was also present during attacks in migraine patients without aura (P < 0.02). No significant variations were observed between headache-free periods and attacks in tension-type headache patients. Reduced NPY levels in the interictal period can be considered further evidence of the derangement of the sympathetic function in the course of migraine, particularly that with aura. The increase in NPY levels during migraine attacks could be an expression of sympathetic activation, even though the functional status of this system is less efficient.

Role of viruses in the etiopathogenesis of multiple sclerosis

Epidemiological studies performed to identify the possible cause of Multiple Sclerosis (MS) suggest that an environmental agent could be involved in its etiopathogenesis. For a long time it has been hypothesized that this agent was a virus, but until now no virus specific to MS has been consistently identified. Animal models indicate that the demyelination of the central nervous system can be induced by certain families of viruses, but the implication of this in the etiopathogenesis of MS has not been clearly demonstrated. Morbilliviruses were the most studied. Research on this subject arose from the observation of the similarity between the brain lesions occurring in MS and encephalitis caused by the measles virus (Subacute Sclerosing Panencephalitis). Antimeasles, antirubella, antiherpes zoster antibodies have been found in the blood and the cerebrospinal fluid of MS patients, but the relationship between this finding and the disease is not clear. It has recently been proposed that the pathogenetic immune response in the brain of MS patients might be directed predominantly towards antigens of a DNA virus, such as JCV. This preferentially infects glial cells and causes a demyelinating syndrome in immunodeficient subjects, called Progressive Multifocal Leucoencephalopathy. The target JC viral antigens in MS could be synthesized during transient viral reactivation. A recent hypothesis is that retroviruses may intervene in the etiopathogenesis of MS. Strong interest has been taken in HTLV-I after its identification in Tropical Spastic Paraparesis, a disease with certain similarities to MS. Serologic and polymerase chain reaction findings from various authors have suggested an association between this human retrovirus and MS. However more recent data are not consistent with this. Current experiments aimed at detecting retroviral particles in long-term cultured peripheral blood monocytes and cerebrospinal fluid mononuclear cells in MS could clarify whether these cells provide a reservoir for such viruses, with a latency of many years without expression at brain level.
