This study reports about 51 COVID-19 patients, mostly healthcare providers,(median age was 42
[25–71] years, and 45% were female, 33% had severe COVID-19 while the remaining 67% had moderate
COVID-19, percentage of hospitalisation was 57%). They underwent cardiopulmonary exercise stress
test 3 months after the second wave of the pandemic in Turkey (the latency time between evaluation
and diagnosis is not better specified).
Main findings : 1)Dyspnoea on exertion was the common clinical complaint of the patients. 2) The
peak VO2 values of COVID-19 survivors decreased, and simultaneously, their exercise performance
decreased due to peripheral muscle involvement. 3) the percentage of the maximum predicted VO2 max
value was lower in male than in female COVID-19 survivors; 4)there was a positive correlation
between the percentage of the predicted VO2 max value and the age. So, these results suggested that
COVID-19 significantly affects young men among COVID-19 survivors. |

This study reports about 81 COVID-19 patients (51 (63%) male, mean age 61±13 years, Mean Body Mass
Index 27.8±4.5kg/m^2). They were assessed at 6 weeks after hospital discharge. The main finding is
represented by the rate of change in cardiopulmonary function and psychological impairment after
hospitalization. The majority of COVID-19 patients had residual symptoms at the outpatient clinic 6
weeks after discharge, mainly dyspnea on exertion as assessed by NYHA class. Patients showed
relatively good psychological adjustment and limited prevalence of depression, anxiety, or PTSD
symptoms (ranging from 5-17%). A lower pulmonary diffusion capacity correlated with functional
status, dyspnea was found. DLCOc value was significantly lower in the ICU group versus the non-ICU
group (mean difference 12.5%P=0.01). Also, FEV1 and FVC were significantly lower in de ICU group
than in the non-ICU group (mean difference FEV1 14.9%;P<0.001; mean difference FVC 15.4%;P<0.001;
respectively). CT Severity index was significantly higher in the ICU group (15.6±5.2) compared
to non-ICU patients (10.8±3.6) (P<0.001). Patients with a higher NYHA class (2-3) had
significantly lower DLCOc values (75±17% vs 83±13%, P=0.040). |

This study reports about 30 severe COVID-19 patients requiring invasive mechanical ventilation in
ICU (mean age 66.06 years, 53.33% were male. ) equally randomized into the two groups: patients who
underwent photobiomodulation therapy combined with static magnetic field and placebo control group.
The length of ICU stay was not significantly different between the PBMT-sMF and placebo groups
(16.26 and 23.06 days, respectively). In contrast, PBMT-sMF was significantly associated with
reduced diaphragm atrophy, improved ventilatory parameters and lymphocyte count, and decreased
C-reactive protein levels and hemoglobin count. |

This study reports about 817 COVID-19 patients (mean age 44±17; 61.1%females).The mean interval
between initial positive PCR for SARS-CoV-2 and survey response was 68.4 days. Main findings :
persistent symptoms (>28 days) are common in patients after resolution of acute COVID-19 disease and
lead to impairment in the ability to participate in social roles (43.2%) and physical function (pain
17.8%, and fatigue 16.2%); PROMIS® scales reliably assess these symptoms and are comparable to
findings in other survey studies; post COVID impairments prevalence and characteristics were
influenced by being young (44 years), white (87%), and female (61%). |

This study reports about 42 COVID-19 patients with mild to moderate symptomatology in the acute
stage (patients with positive PCR test and/or antigen test results in the last forty days were in
home confinement). Subjects were random assigned to receiving either breathing exercises through
telerehabilitation tools (mean age 40.79 ± 9.84) or sedentary activities (mean age 40.32 ± 12.53).
The patients were assessed through video calls on the first and the seventh days. Thirty-eight
subjects, with nineteen in each group, completed the one-week telerehabilitation program.The main
finding is represented by the significant differences for all of the outcome measures in favor of
the experimental group. Breathing exercises through telerehabilitation appeared as a promising
strategy for improving outcomes related to physical condition, dyspnoea, and perceived effort among
people exhibiting mild to moderate COVID-19 symptoms in the acute stage. |

This study reports about 108 COVID-19 patients (mean age 55.6 ± 10.1 years, 45.4% female) undergone
PR as outpatients because of persistent symptoms after COVID-19 . The mean interval between hospital
discharge (or end of the acute phase in non-hospitalized patients) and beginning of PR was 69±75.3
days. Post-hoc analysis of outcome was performed in the three subgroups identified according to the
initial disease severity and the latency of rehab referral and (acute severe: 10.8±11.2 days; severe
after interval:120.6±70.2 days; mild after interval:142.9±55.1days). The main finding is represented
by the improvement with large effect sizes in exertional dyspnea, physical capacity, QoL, fatigue,
and depression observed in the overall group exposed to PR program. There was a trend toward greater
efficacy after ‘severe courses’ of COVID-19 and an earlier start of rehabilitation after the acute
phase of the disease. Results were not compared to a control group. |

This study reports about 47 COVID-19 hospitalized patients who were interviewed about the
persistence of olfactory/gustatory disorders complained of in the acute phase (mean age 34.53(10.82)
years with the most common age group affected as 20–29 years old; mostly females). They were
identified based on a clinical registry review of 435 COVID-19 cases. Patients with previous history
of changes in smell or taste sensation, severely ill at the time of admission, with history of
taking drugs at the time of COVID-19 infection that affect the smell or taste sensation were
excluded. The mean recovery for olfactory dysfunction was 12.1 days. At 6 weeks follow-up only 3
patients were still experiencing incomplete recovery of olfactory dysfunction, and 1 of gustatory
disfunction. |

This study reports about 119 COVID-19 patients (mean age 50.3 years, 44.5% male).They were assessed
up to 8 months of symptom onset. The main finding is represented by the rate of persistent fatigue,
loss of smell, loss of taste, exercise intolerance, and cognitive dysfunction in COVID19 patients up
to 8 months: Forty-nine percent of them had Post-acute sequelae (PASC) at any time during follow-up
(up to 8 months post infection). Ninety-three percent of hospitalized participants developed PASC,
while 23% of those not requiring hospitalization developed PASC. At 90–174 days post SARS-CoV-2
diagnosis, 67% of all participants had persistent symptoms (N = 37 of 55), and 85% percent of
participants who required hospitalization during initial infection (N = 20) still had symptoms.

On PFTs, lung volumes were overall preserved yet, mean percent predicted residual volume was

also mildly reduced (77.2 ± 16.5%). Patients reported residual breathlessness at the time of the
visit (VAS 19.8, p < 0.001). Patients with p/F below 200 during hospitalization had lower percent
predicted forced vital capacity (p=0.005), lower percent predicted total lung capacity
(p=0.012), lower DLCO (p < 0.001) and shorter 6MWT distance (p=0.004) than patients with higher
p/F. Approximately one month after hospital discharge, patients with COVID-19 can have residual
respiratory impairment, including lower exercise tolerance. The extent of this impairment seems
to correlate with the severity of respiratory failure during hospitalization. |

|
This study reports about 205 COVID-19 patients hospitalized in general wards (69.28 ± 17.52 years,
Charlson 3.74 ± 2.62, mean hospital stay 16.8 ± 13.0 days). The main finding is represented by a
high prevalence and burden of oropharyngeal dysphagia and malnutrition in patients hospitalized in
COVID-19 wards with a high rate of symptom persistence at 6 months . At admission, Barthel Index was
81.3 ± 30.3, dysphagia prevalence 51.7% (44.1% impaired safety of swallow); and 45.5% developed
malnutrition with a mean weight loss of 10.1 ± 5.0 kg during hospitalization. Dysphagia was an
independent risk factor for malnutrition during hospitalization, and hospitalization was prolonged
in patients with malnutrition compared with those without (21.9 ± 14.8 vs 11.9 ± 8.9 days,
respectively). Dysphagia was independently associated with comorbidities, neurological symptoms, and
low functionality. At 6-month follow-up, the prevalence of dysphagia was still 23.3% and that of
malnutrition only 7.1%. Patients with dysphagia at discharge showed reduced 6-month survival than
those without at discharge (71.6% vs 92.9%). In contrast, those with malnutrition at discharge did
not show 6-month survival differences compared to those without. The results suggest that optimizing
the management of malnutrition might shorten the hospitalization period but optimizing the
management of dysphagia will likely impact the nutritional status of COVID-19 patients and improve
their clinical outcomes and survival after hospital discharge. |

patient belong to 20-40 age group,35% belong to 40-60 age group while only 8% were 60 years and
above. No respondent was below 20 years of age). The main finding is represented by the high
prevalence of post covid symptoms: 87% patients developed one or more. Weakness was reported to be
most common problem (55%), followed by body ache (26%) and neuropsychiatric symptoms such as
difficulty in concentration and insomnia (22%). Every fifth patient reported that symptoms persisted
for more than 1 month. Though most of the respondents classified their symptoms as mild and moderate
(52.5% and 37.9% respectively), 47% of the symptomatic patients have to take some treatment for
these symptoms. |

This study reports about 76 COVID-19 patients assessed 4 months after acute illness (mean age was
49.6 ± 17.4, and 43.3% were male), 35 of which were outpatients with mild disease and 41 were
hospitalized due to COVID-19 (16 with critical disease requiring mechanical ventilation, 25 with
moderate-severe disease). The main finding is represented by the rate of persistent respiratory
symptoms (44 patients,58%) at 4-month follow-up. Significant pulmonary function impairment was
prevalent in 40 patients (52.6%) occurring among all disease severities. The most common cause was
reduced DLCOcSB (51.3%), followed by reduced TLC and FVC. The severity of the pulmonary function
impairment was significantly associated with mechanical ventilation. Further risk factors for DLCO
impairment were COPD, SARS-CoV-2 antibody-Titer, and in hospitalized patients CT score. Gas exchange
abnormalities were revealed upon cycle exercise in 1/5 of patients with mild disease courses and no
preexisting pulmonary condition. |

in the RD compared to the NRD group after, but not before, recovery. No difference was found between
the RD subjects who received corticosteroid as a treatment and those who did not. An increased risk
for severe forms of COVID-19 is estimated in RD patients. This risk is possibly attributable to a

This study reports about 279 COVID-19 patients (178 (63.8%) male, mean age 71 years). They were
assessed 90 days after discharge. The main finding is represented by the prevalence of fatigue
(8.9%)
followed by cough (4.3%), breathlessness (1.8%), dizziness (1.4%), myalgia (1.1%), loss of smell and
taste (0.8%), and chest discomfort (0.7%). There was no difference in the prevalence of persisting
symptoms between men and women. The prevalence of post-COVID-19 syndrome (two or more clinical
features) was significantly high among severe to critical illness patients (14% vs. 6%) when
compared with mild to moderate ilness patients (p = 0.50).

This study reports about 279 COVID-19 patients older than 65 (178 (63.8%) male, mean age 71 years),
who were interviewed 90 days after hospital discharge. Clinically, 58.4%) patients suffered from
mild/moderate disease, whereas 41.6% from severe/critical COVID-19. The main finding is represented
by the prevalence of fatigue (8.9%) followed by cough (4.3%), breathlessness (1.8%), dizziness
(1.4%), myalgia (1.1%), loss of smell and taste (0.8%), and chest discomfort (0.7%). There was no
difference in the prevalence of persisting symptoms between men and women. 23.6% patients reported
the presence of at least one clinical feature while 9.3% had two or more clinical features, with
this risk being greater among severe to critical illness patients compared with mild to moderate
ilness patients (14% vs. 6%) (p = 0.50). Most older adults retained their baseline functional status
after 90 days of recovery from acute COVID-19.

This study reports about 96 patients (median age 57; 55.2% females; 32.3% hospitalised)
systematically assessed at 5, 9, and 12 months after COVID-19 symptom onset.
The main findings are represented by: 1) At month 12, only 22.9% of patients were completely free of
symptoms and the most frequent symptoms were reduced exercise capacity (56.3%), fatigue (53.1%),
dyspnoea (37.5%), concentration problems (39.6%), problems finding words (32.3%), and sleeping
problems (26.0%). 2) Compared to patients without symptoms, patients with at least one long COVID
symptom at 12 months did not differ significantly with respect to their
SARS-CoV-2-antibody levels, but had a significantly reduced physical and mental life quality
compared to patients without symptoms. 3) Females showed significantly more neurocognitive symptoms
than males. 4) Several neurocognitive symptoms were associated with ANA titre elevations rendering
autoimmunity a potential cofactor in aetiology of long COVID. |

assessed at 3 months after hospital. The main finding is represented by a reduction of ventilatory
efficiency in 15% of participants and of breathing reserve <15% in 16% . Oxygen pulse <80% of
predicted was found in 18%. Dyspnea (mMRC ≥1) was reported by 38%. In participants treated at
ICU vs. non-ICU, mean peak (SD) VO2 % of predicted were 82 (15)% and 90 (17)% (p=0.004),
respectively. Ventilation, breathing reserve, and ventilatory efficiency were similar between
the ICU and non-ICU groups.. |

This study reports about 20 COVID-19 patients (age: 64.1 ± 9.9 years, 75% male) who participated in
unsupervised Pulmonary Rehabilitation (uns-PR) program for eight weeks. The main findings were that
after uns-PR significant improvement were observed in all outcome measures, during 6MWT (i.e.
systolic blood pressure, heart rate , oxygen saturation, dyspnea at the end of 6 MWT, distance ,
estimated O2 uptake, plasma antioxidant capacity, body composition parameters and muscle mass). The
authors support the implementation of unsupervised pulmonary rehabilitation programs in patients
following COVID-19 recovery, targeting the improvement of many aspects of long COVID-19 syndrome.

and 13 age-matched healthy controls (mean age 21 years in COVID patients, 27 years in control
subjects , 61% male in either group).They were assessed up to 25 days after testing positive for
SARS-CoV-2. The main finding is represented by higher systolic blood pressure, end systolic arterial
pressure, and rate pressure product in the SARS-CoV-2 group during exercise at 45%MVC compared with
controls; lower brachial artery BF and brachial artery vascular conductance at both 30%MVC .The
shear-induced dilation of the brachial artery
increased similarly across exercise intensities in the two groups, suggesting the decrease in
exercising blood flow may be due to microvascular impairments.

This study reports about a total 675 COVID-19 patients interviewed after 12 weeks of hospital
discharge (of which, 129 were high-risk pneumonia patients , mean age 57.1±12.9; 68%male; and 376
were low-risk pneumonia patients, mean age 59.3±16.2; 59%male), or after 12 weeks of confirmed or
suspected COVID (n=130 home treated subjects, mean age 46.8; ±12.9; 42%male).
The main findings is represented by the high prevalence of physical health and mental health
symptoms in hospital-treated patients following both ‘high-risk’ and ‘low-risk’ acute COVID
pneumonia and in community-referred patients. The most common was fatigue (50.3% of high- risk
patients, 46.8% of low risk, and 82.3%of community ). Pneumonia severity in the acute phase is not a
predictor of long COVID symptoms. |

This study reports about 146 subjects, 95 recovered from severe/critical COVID-19 (SPs), 51
recovered from mild/moderate disease (MPs). Volunteers who recovered from asymptomatic COVID-19 from
an isolation hotel (28) and uninfected healthy controls from the community (42) were recruited as
controls. COVID -19 subjects were assessed 3 months after hospital discharge. The SGRQ scores were
highest in the SPs, while APs had slightly higher SGRQ scores than those of HCs; 85.1% of SPs and
68.0% of MPs still had residual CT abnormalities, mainly ground-glass opacity (GGO) followed by
strip-like fibrosis at 3 months after discharge, but the pneumonic lesions were largely absorbed in
the recovered SPs or MPs relative to findings in the acute phase. Pulmonary function showed that the
frequency of lung diffusion capacity for carbon monoxide abnormalities were comparable in SPs and
MPs (47.1 vs. 41.7%), while abnormal total lung capacity (TLC) and residual volume (RV) were more
frequent in SPs than in MPs (TLC, 18.8 vs. 8.3%; RV, 11.8 vs. 0%). |
